Description

Charging box, TWS Bluetooth headset adapted to the charging box, and components thereof

technical field

The present application relates to the field of wireless earphones, and in particular, to a charging box, a TWS Bluetooth earphone adapted to the charging box, and components thereof.

Background technique

TWS in the TWS Bluetooth headset is the abbreviation of True Wireless Stereo, which is translated as true wireless stereo. The realization of this technology is based on the development of chip technology. Technically speaking, it means that the mobile phone is connected to the main speaker, and then the main speaker is wirelessly connected to the slave speaker through Bluetooth, so as to realize the true wireless separation of the left and right channels of Bluetooth. When the slave speakers are not connected, the master speakers return to mono sound quality. TWS technology has been applied to the field of Bluetooth headsets, so it has also spawned the current hot new product-TWS Bluetooth headsets.

Compared with ordinary bluetooth earphones, TWS true wireless bluetooth earphones have the following advantages: 1) No wired connection is required, and the left and right earphones form a stereo system through bluetooth, which improves listening to songs, calls, and wearing; 2) External true wireless bluetooth earphones The method of wire connection is completely abandoned, and the host can work alone, and hands-free calls can be mastered; 2) It is ergonomic, natural and comfortable to wear, and there will be no problem of entanglement of the earphone wire in the past.

Since the TWS bluetooth earphones do not need a wired connection, the left and right earphones form a stereo system through bluetooth, which improves listening to songs, calls, and wearing them. Production has repeatedly been in short supply.

Usually TWS Bluetooth headsets are also equipped with a charging box. This often involves judging whether the headset is out of the box or in the box, so as to control accordingly. At present, most of the mainstream charging box in and out detection methods are mechanical switch type or HALL type using Hall element. Among them, the mechanical switch type often uses a light touch switch. When the earphone is placed in the box, the switch will be pressed to determine whether the box is in the box or into the box; the HALL type adopts the magnetic sensor detection method, and puts a magnet in a specific position in the earphone. When the earphones are put into the box, the magnets will be close to or away from the HALL element to make different changes, so as to determine whether the box is in the box or not.

The mechanical switch type is easier to implement in the charging box where the TWS Bluetooth headset is placed horizontally, but it is difficult to implement in the charging box where the TWS Bluetooth headset is placed vertically. The HALL type is placed in the charging box of the TWS Bluetooth headset vertically. Due to the small space for the headset, if there are many magnets, it is easy to interfere with the HALL components, which is difficult to achieve.

Therefore, it is necessary to solve the above-mentioned deficiencies in the in-out-box detection of the TWS Bluetooth headset by the charging box.

Referring to FIG. 1A , a schematic diagram of a scene of a TWS Bluetooth headset placed horizontally according to an embodiment is shown. Referring to FIG. 1B , it is a schematic diagram of a scene of the vertically placed TWS Bluetooth headset described in an embodiment of the application. Specifically, the mechanical switch type is easier to implement in the charging box where the TWS Bluetooth headset is placed horizontally, but the accommodation cavity space for placing the headset in the charging box where the TWS Bluetooth headset is placed vertically is often narrow, and the contact between the headset and the mechanical switch The situation cannot be determined, and it is easy to cause the mechanical switch to fail, resulting in judgment errors. For example, when the earphone is put into the charging box, the earphone does not trigger the mechanical switch because the corresponding position is not pressed, or the mechanical switch delays switching or does not trigger the bomb after the earphone is taken out because the mechanical switch has been under force for too long. verb: move. All of the above situations will cause the judgment error of the mechanical switch, which will affect the normal use of the TWS Bluetooth headset. Therefore, the vertical placement of the TWS Bluetooth headset in the charging box is often ineffective and difficult to achieve.

The HALL type is placed in the charging box of the TWS Bluetooth headset vertically. Due to the small space of the headset, if there are many magnets, placing magnets in a specific position in the headset will easily interfere with the HALL components, which is difficult to implement.

In order to solve the above problems, the present application proposes a charging box, a TWS Bluetooth headset adapted to the charging box, and components thereof.

As shown in FIG. 2, it shows a schematic structural diagram of a charging box and a TWS Bluetooth headset adapted to the charging box in an embodiment of the present application. As shown in the figure, the figure includes: the charging box 1 and the TWS Bluetooth headset 2 .

Charging case 1

The charging box 1 includes: a box body 11, and a accommodating cavity 111 adapted to the structure of the TWS Bluetooth headset 2 is arranged in the box body 11; / The infrared light sensing component 1111 in the box-in state, which generates signals of different levels according to whether infrared light is detected.

The box body 11 is provided with a charging circuit; the bottom of the accommodating cavity 111 is provided with a connector assembly 112, which is respectively electrically connected to the positive and negative electrodes of the charging circuit.

The MCU module is respectively connected with the infrared light sensing component 1111 and the charging circuit, and is used to receive the level signal generated by the infrared light sensing component 1111, and control the on-off of the charging circuit accordingly.

In the present application, in order to solve the insensitivity of the mechanical switch and the additional interference caused by the HALL element, the present application proposes a method of detecting infrared light, specifically the infrared light sensing component 1111 .

In an embodiment of the present application, the infrared light sensing component 1111 includes: an infrared light emitting diode and an infrared sensing tube; the infrared light emitting diode and the infrared sensing tube are symmetrically disposed on the inner wall of the accommodating cavity 111 respectively. on two opposite positions at the same level.

In the present application, the infrared light emitting diode is used to generate infrared light after being activated, and the infrared induction tube is used to detect the infrared light. In addition, in order to ensure the accuracy of detection, the infrared light emitting diode and the infrared induction tube are arranged on the inner wall of the accommodating cavity 111 at two symmetrical opposite positions at the same horizontal height.

It should be noted that, since the space of the accommodating cavity 111 is relatively small, the infrared light emitting diode and the infrared induction tube can be a sheet-shaped infrared light emitting sheet or an infrared sensing sheet. Or the infrared light emitting diode and the infrared induction tube are embedded in the inner wall of the accommodating cavity 111, which does not affect the overall space of the accommodating cavity 111, and does not affect the emission and detection of infrared light.

In this embodiment, the present application uses a combination of an infrared light emitting diode and an infrared induction tube to realize the detection of the TWS Bluetooth headset 2 entering and leaving the box. When the infrared diode emits infrared light, the infrared induction tube receives the infrared light. When the TWS Bluetooth headset 2 is put into the charging box 1, the infrared light will be blocked by the TWS Bluetooth headset 2, and the infrared induction tube cannot receive the infrared light. Based on this, the movement of the TWS Bluetooth headset 2 into and out of the box is detected. .

It should be noted that, in the present application, the diameter of the accommodating cavity 111 is set to match the diameter of the TWS Bluetooth headset 2 , that is, the diameter of the accommodating cavity 111 is close to or slightly larger than the diameter of the TWS Bluetooth headset 2 . To ensure that when the TWS Bluetooth headset 2 is put into the accommodating cavity 111, the infrared light emitted by the infrared diode will not be detected by the infrared induction tube due to refraction or reflection.

In an embodiment of the present application, the connector assembly 112 is a Pogo Pin connector assembly or a pin connector assembly, and the connector assembly 112 is arranged on the TWS Bluetooth headset 2 put into the box body 11 . The connector assembly 221 is adapted to the Pogo Pin connector assembly, and the Pogo Pin connector assembly is a contact type connector.

In this embodiment, the MCU module is electrically connected to the charging circuit, because the infrared light sensing component 1111 generates signals of different levels when infrared light is detected and extrauterine light is not detected. For example, when the TWS Bluetooth headset 2 is placed in the charging box 1, the TWS Bluetooth headset 2 will block the infrared light emitted by the infrared light emitting diode, and the infrared induction tube cannot detect the infrared tube light, and a high-level signal can be generated at this time; on the contrary, if When the TWS Bluetooth headset 2 is taken out from the charging box 1, the TWS Bluetooth headset 2 will not block the infrared light emitted by the infrared light emitting diode, and the infrared induction tube can detect the infrared tube light, and a low-level signal can be generated at this time. The MCU module can have different level signals as the judgment of the TWS Bluetooth headset 2 being out of the box or in the box, so as to control the on-off of the charging circuit to reduce unnecessary power consumption.

In this application, the charging box 1 has two structural embodiments, one is that the TWS Bluetooth headset 2 serves as the cover of the charging box 1, and the other is that the charging box 1 corresponds to the box. The body 11 is also provided with a cover body 12 .

By arranging the Hall element 113 at the edge of the entrance of the accommodating cavity 111, and correspondingly arranging the magnet 211 on the TWS Bluetooth headset 2, on the one hand, the distance between the Hall element 113 and the magnet 211 is changed. The Hall element 113 is turned off or turned on; on the other hand, the magnetic force between the Hall element 113 and the magnet 211 is also used to make the TWS Bluetooth headset 2 It serves as the cover 12 of the charging case 1 as described in FIG. 2 .

It should be noted that, the Hall element 113 is electrically connected to the MCU module, so that the MCU module can obtain the state of the Hall element 113 being disconnected or turned on, thereby further enabling the charging The box 1 determines whether the TWS Bluetooth headset 2 is out of the box or in the box.

In this embodiment, by disposing a Hall element 113 at the edge of the entrance of the accommodating cavity 111, and correspondingly disposing a magnet 121 on the TWS Bluetooth headset 2, the distance between the Hall element 113 and the magnet 121 is determined by the distance between the Hall element 113 and the magnet 121. The change causes the Hall element 113 to be turned off or turned on.

It should be noted that, the Hall element 113 is electrically connected to the MCU module, so that the MCU module obtains the state that the Hall element 113 is disconnected or turned on.

It should be noted that, because the MCU module, the charging circuit, and the communication module below are not limited to specific structures, the above-mentioned Fig. 2, Fig. 3, Fig. 4A, and Fig. 4B are not drawn, but it should be understood that all The MCU module, the charging circuit, and the communication module are present in the charging box 1 described in this application.

As shown in FIG. 5 , a schematic diagram of a module of the charging case described in an embodiment of the present application is shown. Corresponding to the first embodiment or the second embodiment, the charging box further includes a communication module 503, and the MCU module 504 can also implement control functions corresponding to different situations. As shown in the figure, the infrared sensing component 501 , the charging circuit 502 , and the communication module 503 are respectively electrically connected to the MCU module 504 .

Specifically, please refer to the schematic circuit diagram of the infrared sensing assembly shown in FIG. 6. As shown in the figure, the infrared sensing assembly 501 includes: an infrared light emitting diode, an infrared sensing tube, a plurality of resistors, and a triode.

Specifically, the charging box 1 further includes: a communication module 503 for communicating with the TWS Bluetooth headset;

The MCU module 503 is also used to turn on the infrared light sensing component 501 when it is detected that the Hall element 113 as shown in FIG. 2 or FIG. 3 is turned on; The level signal determines whether the infrared light is detected; if the infrared light is not detected, the charging circuit 502 is turned on to discharge, and a standby command is sent to the TWS Bluetooth headset; if detected For the infrared light, send a running command to the TWS Bluetooth headset;

And/or, when it is detected that the Hall element 113 as shown in FIG. 2 or FIG. 3 is disconnected, it is judged whether it detects the infrared light according to the level signal generated by the infrared light sensing component 501; if When the infrared light is detected, the infrared light sensing component 501 is turned off, and the charging circuit 502 is disconnected; if the infrared light is detected, the charging circuit 502 is turned on for discharging, and the charging circuit 502 is turned off. Send a standby instruction to the TWS Bluetooth headset.

In this embodiment, the communication module 503 is mainly used to communicate with the TWS bluetooth headset, and more specifically, through the MCU module 504, to send a motor command or a running command to the TWS bluetooth headset.

The communication module 503 can be one or more wireless communication methods and combinations thereof. Communication methods include: Internet, CAN, intranet, wide area network (WAN), local area network (LAN), wireless network, digital subscriber line (DSL) network, frame relay network, asynchronous transfer mode (ATM) network, virtual private network (VPN) ) and/or any one or more of any other suitable communication networks.

In this embodiment, it can be seen from the above that whether the infrared light sensing component 501 detects infrared light, it can be indirectly judged that the TWS Bluetooth headset is in and out of the box. On or off state, based on this, the MCU module 504 can implement functions corresponding to different scenarios.

Referring to FIG. 2 or FIG. 3 , for example, firstly, it is determined whether the cover body 12 as shown in FIG. 2 is opened or not according to the on or off state of the Hall element 113 , or corresponding to the first embodiment ( Corresponding to FIG. 3 ), it is to determine whether the TWS Bluetooth headset 2 serving as the cover 12 in FIG. 2 is turned on.

Assuming that the Hall element 113 is turned on at this time, it can be judged that the cover body 12 is open at this time, then in the actual scene, the next step may be to put in the TWS Bluetooth headset 2 for charging or take out the TWS Bluetooth headset 2 for use. If it is accurate, the infrared light sensing element 1111 needs to be turned on, and it is determined whether the infrared light is detected according to the level signal generated by the infrared light sensing element 1111 .

If the infrared light is not detected, it can be determined that there is the TWS Bluetooth headset 2 in the box body 11, that is, the TWS Bluetooth headset 2 is in the box state, then the charging circuit is turned on to perform Discharge, and send a standby command to the TWS Bluetooth headset 2 to reduce the power consumption of the TWS Bluetooth headset 2 .

If the infrared light is detected, it can be determined that the TWS Bluetooth headset 2 does not exist in the box body 11, that is, the TWS Bluetooth headset 2 is in an out-of-box state, and a running instruction is sent to the TWS Bluetooth headset 2, to get it to work.

For another example, assuming that the Hall element 113 is disconnected at this time, it can be judged that the cover 12 is closed at this time, then in the actual scene, the next step may be the TWS Bluetooth headset 2 has been charged or has been charged. Take out the TWS Bluetooth headset 2 for use. Since the infrared light sensing component 1111 is still in an open state (except when leaving the factory), in order to judge accurately, it is necessary to judge whether the infrared light sensing component 1111 detects the infrared light at this time. .

If the infrared light is detected, it means that the TWS Bluetooth headset 2 is out of the box at this time. In order to reduce the unnecessary power consumption of the infrared light sensing component 1111 and the charging circuit, the infrared light sensing component is turned off. 1111, and disconnect the charging circuit, because when it is judged that the cover 12 is open, a power-on command has been sent to the TWS Bluetooth headset 2 when it is out of the box, so no power-on command is sent here.

If the infrared light is not detected, it means that the TWS Bluetooth headset 2 is in the box state at this time, then the charging circuit is turned on for discharging, and a standby command is sent to the TWS Bluetooth headset 2 to make The TWS Bluetooth headset is on standby.

The above functions can be performed by the MCU module, that is, the needs and judgments of daily use between the TWS Bluetooth headset 2 and the charging box 1 can be basically realized.
