The terminology used in the description presented herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, in one aspect, a headset 1000 is provided. The headphone 1000 includes two headphone units 200 and a headband 100, the two headphone units 200 are respectively provided at both ends of the headband 100, and when worn, the headband 100 spans both sides of a user's head, and the two headphone units 200 are respectively located near both ears of the user. The earphone unit 200 includes an earmuff assembly 201, a driver and an earmuff assembly 202, etc., the earmuff assembly 201 is used for being connected with the headband 100 and is provided with an acoustic outlet, the driver is arranged in the earmuff assembly 201 and is used for vibrating and sounding so as to enable sound waves to be transmitted from the acoustic outlet, and the earmuff assembly 202 is arranged on one side of the earmuff assembly 201, provided with the acoustic outlet, and is used for covering or partially covering the ears of a user so as to enable the sound waves to be transmitted towards the auricle meatus of the user.

It is apparent that the above-described headset 1000 generally has a large volume, and some of the headset 1000 has a folding function for easy storage and accommodation. Therefore, the headset 1000 has an unfolded state for wearing and a folded state for easy storage, and in the folded state, the headset 1000 occupies a smaller space and is more convenient to carry. Conventionally, by folding the headphone unit 200 with respect to the headband 100, the structure of the headphone 1000 is made more compact, reducing space occupation. However, in the related art, the folding positioning angle of the earphone unit 200 is single, and the connection between the earphone unit 200 and the headband 100 is loose, so that the user experience is poor.

In view of this, referring to fig. 1 and 2, another aspect of the present application proposes a headband 100, where the headband 100 includes a frame 10 and two sets of folding assemblies 30. The whole of the frame body 10 is arc-shaped, and two groups of folding assemblies 30 are respectively connected with two ends of the frame body 10. It will be appreciated that, taking the example that the headband 100 is applied to the headphone 1000, when the user wears the headphone 1000 on his/her head, the headband 100 is in a worn state, the curved frame body 10 encloses a wearing space 101 located in the middle, and a part of his/her head (wearing part) is located in the wearing space 101 to be fitted with the headband 100. The frame body 10 is a main body structure of the headband 100, and is used for providing a mounting position and support for components such as the folding assembly 30, and the frame body 10 in an arc-shaped arrangement can be attached to the head of a user when the headset 1000 is worn, so that a good wearing effect is achieved. The folding assembly 30 is used to mount the earphone unit 200 on the headband 100, and the headband 100 secures the earphone unit 200 to the head of a user.

The frame 10 and the folding component 30 may be made of one or more materials selected from metal, plastic, leather, etc., which is not limited in the embodiment of the present application.

Referring to fig. 2 in combination, the folding assembly 30 includes a slide arm 31 and an eardrum link 33, the slide arm 31 being coupled to the frame body 10, the eardrum link 33 rotatably coupling one end of the slide arm 31 away from the frame body 10 and being used to couple the earphone unit 200 (the eardrum assembly 201) so that the earphone unit 200 can swing with the eardrum link 33 with respect to the frame body 10.

In one embodiment, the end of the frame 10 is provided with a mounting cavity (not shown) extending and an opening communicating with the mounting cavity, the sliding arm 31 is slidably disposed in the mounting cavity, and has an end portion exposed outside the mounting cavity all the time through the opening, and the ear shell connector 33 is rotatably connected with one end of the sliding arm 31 exposed outside the mounting cavity. It will be appreciated that the sliding arm 31, when slid within the mounting cavity, moves the concha connector 33 and the earpiece unit 200 together. To conform to the shape of the frame 10, the mounting cavity may optionally be configured to extend in an arc shape, and the sliding arm 31 may also be configured in an arc shape so as to be capable of sliding in the mounting cavity along the field. In this way, the sliding arms 31 provided in a sliding manner allow the length of the headband 100 to be varied, thereby improving the usability of the headband 100. In the folded state, the sliding arm 31 can be located mostly within the mounting cavity, thereby further reducing the volume of the headset 1000 when stowed.

Referring to fig. 1 to 3, the earmuff connector 33 has a substantially rod shape, one end of which is connected to the earmuff assembly 201, and the other end of which forms a connection end 331, and the connection end 331 is rotatably connected to the slide arm 31 to have a rotation axis S. The end of the sliding arm 31 away from the frame body 10 is provided with a connecting groove 3131, and the connecting end 331 is located in the connecting groove 3131. Optionally, the headband 100 further includes a shaft pin 35 passing through the sliding arm 31 and the connection end 331, and the side wall of the connection groove 3131 and the connection end 331 are provided with through holes for the shaft pin 35 to pass through, and the connection end 331 can rotate around the shaft pin 35 relative to the sliding arm 31. When the connection end 331 is rotated, the earmuff connector 33 as a whole can be rotated into the wearing space 101 or away from the wearing space 101. It will be appreciated that when the ear shell connector 33 is far from the wearing space 101, the ear shell connector 33 is in an unfolded state, the earphone unit 200 is not in the wearing space 101, and the wearable headset 1000 is used at this time, and when the ear shell connector 33 is in the wearing space 101, the ear shell connector 33 is in a folded state, and the earphone unit 200 is folded and stored in the wearing space 101, so that the space volume of the headset 1000 when stored can be reduced, and the portable headset is convenient to carry.

In the embodiment of the application, one of the inner side of the connecting groove 3131 and the connecting end 331 is provided with a first limiting portion 50, and the other is provided with at least two second limiting portions 70. Illustratively, the first limiting portion 50 may be disposed at an end of the sliding arm 31 and proximate to the connecting slot 3131, and the at least two second limiting portions 70 may be disposed at a spaced apart location on the concha connector 33 and proximate to the connecting end 331. When the ear shell connector 33 is in the unfolded state, the first limiting part 50 is clamped with one of the second limiting parts 70, so that the connection and fixation of the ear shell connector 33 and the sliding arm 31 are tighter, the ear shell connector 33 can be more firmly kept relatively fixed with the sliding arm 31, the unfolded state is kept, the headset 1000 is convenient for a user to use, when the ear shell connector 33 is in the folded state, the first limiting part 50 is clamped and fixed with the other second limiting part 70, the ear shell connector 33 can be kept in the folded state, the structure is more compact, and the occupation space of the headset 1000 is prevented from being enlarged due to the fact that the ear shell connector 33 is loose during storage.

The first limiting portion 50 and the second limiting portion 70 may adopt a mode of adapting a protrusion to a limiting groove, adapting a magnetic attraction piece, and the like, which is not limited in the embodiment of the present application. Of course, the first limiting portion 50 and the second limiting portion 70 are not limited to be connected in a folded state and an unfolded state, and the earshell connector 33 can realize a more reliable hovering effect under a plurality of angles by providing a plurality of second limiting portions 70.

In this way, the first limiting part 50 and the at least two second limiting parts 70 are respectively arranged on the earmuff connector 33 and the sliding arm 31, so that the earmuff connector 33 can stably hover at least in a plurality of places such as an unfolding state and a folding state, the structure of the folding assembly 30 is more compact, the movement and hovering of the earmuff connector 33 relative to the sliding arm 31 are more reliable, the loosening phenomenon is reduced or avoided, and the user experience is improved.

Further, in the embodiment of the present application, the connection end 331 is in interference fit with the connection groove 3131. Even though the connection end 331 is interference fit with the connection groove 3131, a margin for rotation of the connection end 331 in the connection groove 3131 is maintained by a sufficient external force (a force acting on the earphone unit 200 or the earbud connector 33 to swing the earbud connector 33). In the case that the connecting end 331 is in contact with the inner wall of the connecting groove 3131 at any position in the swinging range, the headset 1000 connector can maintain a relatively stable posture relative to the sliding arm 31, the possibility of loosening is reduced, and the structure is more compact and firm.

In this way, the connection end 331 of the ear shell connector 33 is in interference fit with the connection groove 3131 of the sliding arm 31, so that the ear shell connector 33 is tightly connected with the sliding arm 31, and the possibility of loosening is reduced on the premise of not affecting the rotation of the connection end 331 relative to the connection groove 3131.

To achieve an interference fit with the connection end 331, the connection groove 3131 has opposite sidewalls that grip the connection end 331. The opposite side walls of the connecting groove 3131 are spaced apart and define a notch of the connecting groove 3131, and the connecting end 331 extends into the connecting groove 3131 from the notch of the connecting groove 3131. The connecting groove 3131 may be integrally defined by the slide arm 31, or the slide arm 31 may be provided as a separate structure.

Referring to fig. 3 to 5, in some embodiments of the present application, the sliding arm 31 includes a main body 311 and a spring 313. The main body 311 is slidably connected to the frame 10 and is disposed in a substantially arc shape, the main body 311 is slidable along the mounting cavity, and has an end portion exposed outside the mounting cavity, and the elastic piece 313 is connected to the end portion.

In some alternative constructions, the spring plate 313 itself defines the attachment slot 3131. For example, the elastic piece 313 is substantially U-shaped, and the bottom thereof is fixedly connected to the main body 311, and two side portions are formed to clamp two opposite side walls of the connecting section, thereby forming the connecting groove 3131. In this way, the two side walls of the connecting slot 3131 can clamp the connecting end 331 under the action of self elasticity, so that interference fit between the connecting slot 3131 and the connecting end 331 is realized.

Referring to fig. 3, a connecting slot 3131 is disposed at an end of the main body 311 away from the frame 10, and the elastic piece 313 is fixed inside the connecting slot 3131 and contacts the connecting end 331. For example, the elastic piece 313 may be in a sheet shape, and one end of the elastic piece is fixed on the bottom wall of the connecting slot 3131, and is spaced from one of the side walls of the connecting slot 3131. The elastic piece 313 can elastically deform and is abutted against one side of the connecting end 331 due to elasticity of the elastic piece, and the other side of the connecting end 331 is pressed against the side wall of the connecting groove 3131 under the elastic action, so that interference fit is realized.

Alternatively, referring to fig. 4, in an embodiment, the elastic piece 313 includes a fixing segment 3133 and two limiting segments 3135. The fixed segment 3133 is connected to the groove bottom wall of the connecting groove 3131. For example, the fixing segment 3133 and the bottom wall of the connecting slot 3131 are provided with hole structures, and the fixing segment 3133 is fixed to the bottom wall of the connecting slot 3131 by a screw penetrating through the fixing segment 3133. Of course, the fixing segment 3133 may be connected to the bottom wall of the connecting slot 3131 by a snap fit or an insert, which is not limited herein. The two limiting segments 3135 are respectively connected to opposite sides of the connecting segment, so that the elastic sheet 313 is generally in a "U" shape. The edges of the two spacing segments 3135 define notches of the attachment slot 3131 such that the attachment end 331 can pass through the notches of the attachment slot 3131 to be interference fit with the attachment slot 3131. As shown, the two limiting segments 3135 are each provided with a through hole, and the shaft pin 35 passes through the connecting end 331 and the two limiting segments 3135, so that the connecting end 331 can rotate around the shaft pin 35 relative to the elastic sheet 313. Alternatively, by forming the two spacing segments 3135 into a substantially "eight" shape, such that the distance between the two spacing segments 3135 increases gradually in a direction approaching the fixed segment 3133, and when the connection end 331 is disposed in the connection slot 3131, the two spacing segments 3135 can clamp the connection end 331, thereby achieving an interference fit between the connection end 331 and the connection slot 3131.

In order to improve the assembly precision, in this embodiment, the two limiting segments 3135 are symmetrically arranged, so that when the elastic change occurs, the deformation of the two limiting segments 3135 is relatively consistent, the alignment precision is ensured, and the damage to the service life of the elastic sheet 313 due to the asymmetric deformation is avoided. One end of the fixed segment 3133 is further extended to be provided with a positioning protrusion, the bottom wall of the connecting groove 3131 is provided with a positioning groove, and the positioning protrusion is positioned in the positioning groove so as to improve assembly accuracy and assembly efficiency, limit displacement of the fixed segment 3133, further improve stability of the elastic piece 313 and avoid loosening phenomenon when the connecting end 331 and the connecting groove 3131 are matched.

Optionally, the elastic piece 313 is a metal piece, has high structural strength, can be elastically deformed, and has long service life. The elastic sheet 313 can be of an integral structure, is convenient to process, and has good structural integrity.

In this embodiment, on the one hand, the elastic piece 313 can realize a tighter clamping effect on the connecting end 331, further avoiding loosening, on the other hand, the elastic piece 313 is arranged in the connecting groove 3131, the connecting end 331 stretches into the connecting groove 3131 to be connected with the connecting groove 3131 in an adapting manner, so that the space of the folding assembly 30 is saved, the structure is more compact, and the main body 311 plays a role in shielding and protecting the elastic piece 313 and the eardrum connecting piece 33, so that the appearance is more concise and attractive.

Referring to fig. 4, in some embodiments, the first limiting portion 50 is disposed on at least one side wall of the connecting slot 3131, and the at least two second limiting portions 70 are disposed on the connecting end 331 and disposed around the rotation axis S, and it can be appreciated that the connecting end 331 rotates around the rotation axis S relative to the sliding arm 31. Of course, it is understood that the first limiting portion 50 and the second limiting portion 70 are disposed on the side wall on the same side of the connecting end 331 so as to be matched with each other.

Specifically, the first limiting portion 50 is disposed on the elastic piece 313, and when the elastic piece 313 has two limiting segments 3135, at least one limiting segment 3135 is provided with the first limiting portion 50, and at least two second limiting portions 70 are disposed at a side of the connecting end 331 facing the elastic piece 313 (limiting segment 3135) at intervals. That is, any of the limiting segments 3135 may be provided with the first limiting portion 50, and the connecting end 331 is provided with at least two second limiting portions 70 towards one side of the limiting segment 3135 provided with the first limiting portion 50, or both limiting segments 3135 are provided with the first limiting portion 50, and correspondingly, both sides of the connecting end 331 are also provided with at least two second limiting portions 70 so as to be matched with both limiting segments 3135. In this way, when the connecting end 331 and the connecting groove 3131 are in interference fit, the connecting end 331 is in a specific position, such as when the earmuff connector 33 is in a folded state or an unfolded state, the connecting end 331 is in limit fit with the elastic piece 313 (the limit section 3135), the limit fit of the connecting end 331 and the elastic piece is tighter due to the clamping force of the interference fit, so that the stability and the reliability of hovering of the earmuff connector 33 at the specific position can be further improved, loosening is further avoided, damping sense is provided when the connecting end 331 rotates relative to the connecting groove 3131, and user experience is improved. In addition, with interference fit and spacing adaptation integration at the adaptation connection of shell fragment 313 and link 331, the structure integrated level is higher, and is compacter, and shell fragment 313 (spacing section 3135) sets up in the side of link 331, and not set up at the top of link 331 to can more save space, make folding subassembly 30's outward appearance more pleasing to the eye, occupation space is littleer.

It is conceivable that if the sliding arm 31 is integrally formed with the first limiting portion 50, and the sliding arm 31 needs to be made of a material having sufficient strength for material selection and machining, the first limiting portion 50 needs to be easily formed, have a certain elasticity, and have a long service life, which is certainly difficult, especially in the case that the first limiting portion 50 has a complex structure. According to the technical scheme provided by the embodiment of the application, the first limiting part 50 is integrated on the elastic piece 313, and the elastic piece 313 and the main body 311 are arranged in a split mode, so that different materials can be selected for the elastic piece 313 and the main body 311, the processing design can be performed in a targeted mode, the production and the processing are facilitated while the design requirements are met, and the production efficiency is improved.

Of course, in other embodiments, the first limiting portion 50 may be disposed on the connecting end 331, and at least two second limiting portions 70 may be disposed on at least one side wall of the connecting slot 3131, so as to still perform the above-described functions and effects. The following embodiment is explained taking the side wall of the connecting slot 3131 provided with the first limiting portion 50 and the connecting end 331 provided with at least two second limiting portions 70 as an example.

Referring to fig. 4 and 5, in an embodiment, the first limiting portion 50 is a limiting protrusion, the second limiting portion 70 is a limiting groove, and when the first limiting portion 50 is in limiting fit with the second limiting portion 70, the limiting protrusion is located in the limiting groove, or when the connecting end 331 rotates, the first limiting portion 50 and the second limiting portion 70 are out of limiting fit, and the limiting groove moves relative to the limiting protrusion along with the rotation of the connecting end 331 until the other limiting groove is in limiting fit with the limiting protrusion.

In this embodiment, the shape of the limiting protrusion may be selected from a circular shape, a square shape, etc., and because the size of the elastic piece 313 is smaller, in order to increase the range of the limiting protrusion within a limited size, the limiting protrusion may extend to the edge of the elastic piece 313 (the limiting segment 3135), which is also convenient for processing. The shape of the limiting groove corresponds to the limiting convex part, so that when the limiting convex part is positioned in the limiting groove, the inner wall of the limiting groove can play a good limiting role on the limiting convex part, the connection tightness degree is improved, and looseness is avoided. Each second limiting portion 70 is provided with at least one limiting groove, and at least two limiting portions are provided with at least two limiting grooves. The rotation axis S of the connection end 331 coincides with the central axis of the shaft pin 35, and opposite side walls of the connection groove 3131 have elasticity such that a distance between the side walls can be elastically varied. When the connecting end 331 rotates, the current limit groove in limit fit with the limit protrusion rotates relative to the limit protrusion, the limit protrusion is abutted to the wall surface of the connecting end 331, which is not provided with the limit groove, the elastic sheet 313 deforms more, the clamping effect on the connecting end 331 is stronger, and the connecting end 331 has damping sense without loosening when rotating, so that the user experience is better. The at least two limiting grooves are disposed at intervals around the rotation axis S, so that the first limiting portion 50 can be adapted to the second limiting portion 70 at different positions by rotating the connecting end 331. But this embodiment selects spacing adaptation form of spacing convex part and spacing recess to use, and simple structure is effective and easily processing, can effectively promote efficiency, reduces processing cost.

With reference to fig. 4 and 5, in an embodiment of the present application, the number of the first limiting portions 50 is two, the number of the second limiting portions 70 is three, and the two first limiting portions 50 and the three second limiting portions 70 are all disposed around the rotation axis S. For convenience of description, the two first limiting portions 50 are respectively identified as a first limiting protrusion 51 and a second limiting protrusion 53, and the three second limiting portions 70 are respectively identified as a first limiting groove 71, a second limiting groove 73 and a third limiting groove 75. In this embodiment, in the unfolded state, the first and second limiting protrusions 51 and 53 are located in the first and second limiting grooves 71 and 73, respectively, and in the folded state, the first limiting protrusion 51 is located in the second limiting groove 73, and the second limiting protrusion 53 is located in the third limiting groove 75. In this way, the technical solution of the embodiment of the present application can increase the contact area between the connection end 331 and the connection groove 3131, and improve the connection reliability.

As shown in fig. 2 and 5, in the embodiment of the present application, at least two second limiting portions 70 are defined to be spaced around the rotation axis S, and two adjacent second limiting portions 70 form an included angle α with respect to the rotation axis S, and satisfy the relationship that α is 85 ° or more and 100 °. If the angle α is greater than 100 °, the earphone unit 200 may interfere with the headband 100 when the ear shell connector 33 is in the folded state, and if the angle α is less than 85 °, the earphone unit 200 may not be well received in the wearing space 101 when folded, resulting in a larger volume of the headset 1000, which is inconvenient to receive. Therefore, in order to facilitate storage and ensure that other structures are not interfered, the application limits the angle to be more than or equal to 85 degrees and less than or equal to 100 degrees, wherein alpha is selected from 90 degrees, 95 degrees, 98 degrees and the like.

The above embodiment explains a specific arrangement of the first stopper 50 and the at least two second stoppers 70 on one side of the connection end 331.
