The image pickup device 60 can be used as an image pickup device of the terminal device 70. When image capture device 60 is in the first position, image capture device 60 is disposed in receiving cavity 73, and image capture device 60 is used as a rear camera of terminal device 70. When image pickup device 60 is rotated 180 ° from the first position to the second position, image pickup device 60 is used as terminal device 70 corresponding to the front camera as terminal device 70. In an embodiment, the image capturing device 60 may further include a battery and a motherboard, the receiver 10, the camera 61, and the battery are all connected to the motherboard, and the battery supplies power to the motherboard. The image acquisition camera can be in communication connection with the terminal equipment 70, and the image shot by the camera 61 is transmitted to the terminal equipment 70. Meanwhile, the terminal device 70 may also charge a battery in the image pickup device 60.

As shown in fig. 3, fig. 5 and fig. 8, the receiver 10 in the image capturing device 60 can be electrically connected to the terminal device 70, and the terminal device 70 can control the receiver 10 to make the receiver 10 emit sound. The image capturing device 60 includes a front side 651 and a back side 652, and when the image capturing device 60 is in the first position (as shown in fig. 3), the front side 651 of the image capturing device 60 faces the side of the terminal device 70 where the back side 72 is located, and the back side 652 of the image capturing device 60 faces the side of the terminal device 70 where the display surface 711 is located. When the image capturing device 60 is in the second position (as shown in fig. 5), the positions of the front side 651 and the back side 652 of the image capturing device 60 are interchanged, the front side 651 of the image capturing device 60 faces the side where the display surface 711 of the terminal device 70 is located, and the back side 652 of the image capturing device 60 faces the side where the back side 72 of the terminal device 70 is located. It will be appreciated that the first sound outlet 410 is located on the side of the image capturing device 60 where the back side 652 is located and the second sound outlet 420 is located on the side of the image capturing device 60 where the front side 651 is located.

As shown in fig. 3, 5 and 8, the receiver 10 of the present application has a function of generating sound on both sides, and may generate sound in a direction toward the first sound outlet 410, i.e., toward the back side 652 of the image pickup device 60, or may generate sound in a direction toward the second sound outlet 420, i.e., toward the front side 651 of the image pickup device 60. Thus, when the image pickup device 60 is in the first position, the first sound hole 75 of the terminal device 70 communicates with the first sound outlet hole 410 of the receiver 10, so that the sound of the receiver 10 emitted from the first sound outlet hole 410 can be heard from the side where the display surface 711 of the terminal device 70 is located. When the image pickup device 60 is in the second position, the first sound hole 75 of the terminal device 70 communicates with the second sound emitting hole 420 of the receiver 10, so that the sound emitted from the second sound emitting hole 420 of the receiver 10 can be heard from the side where the display surface 711 of the terminal device 70 is located. It is understood that the terminal device 70 can control the receiver 10 to only sound from the first sound outlet 410 when the image capturing device 60 is located at the first position, and the terminal device 70 can control the receiver 10 to only sound from the second sound outlet 420 when the image capturing device 60 is located at the second position, although in other embodiments, the first sound outlet 410 and the second sound outlet 420 can also sound simultaneously when the image capturing device 60 is located at the first position or the second position.

Through the arrangement, the telephone receiver 10 does not need to be arranged on the terminal device 70, the top of the terminal device 70 does not need to reserve an accommodating space for installing the telephone receiver 10, and only one sound hole (namely, the first sound hole 75) needs to be arranged on the top of the terminal device 70, so that a larger space can be reserved for the screen on one side of the display surface 711 of the terminal device 70, and the screen occupation ratio of the terminal device 70 is improved. And because the image acquisition equipment 60 can be used as the front camera 61 of the terminal equipment 70, the accommodating space for installing the telephone receiver 10 does not need to be reserved at the top of the terminal equipment 70, and the screen occupation ratio of the terminal equipment 70 is further improved. Meanwhile, no matter the image acquisition device 60 is in the first position or the second position, the telephone receiver 10 can sound towards the display surface 711, so that the terminal device 70 is more convenient to use. Through the technical scheme of the application, the comprehensive screen of the terminal equipment 70 can be better realized.

As shown in fig. 3, 5 and 8, the image capturing apparatus 60 includes a housing 62, and a second sound hole 621 and a third sound hole 622 are provided on the housing 62. When the image capturing device 60 is in the first position, and the second sound hole 621 is located between the first sound outlet 410 and the first sound hole 75, i.e. the first sound outlet 410 and the first sound hole 75 are connected through the second sound hole 621. When the image capturing device 60 is in the second position, and the third sound hole 622 is located between the second sound outlet hole 420 and the first sound hole 75, i.e., the second sound outlet hole 420 and the first sound hole 75 are connected through the third sound hole 622.

The housing 62 is provided with a first rubber ring 63 at an outward end of the second sound hole 621 to enable the first sound hole 75 and the second sound hole 621 to communicate sealingly when the image pickup device 60 is located at the first position. In this embodiment, the first rubber ring 63 is a silicone ring, and when the image capturing device 60 is located at the first position, the first rubber ring 63 is tightly pressed between the housing 62 and the bottom wall 731 of the receiving groove 73, so that no gap exists at the connection between the first sound hole 75 and the second sound hole 621, and the sound transmitted from the first sound output hole 410 by the receiver 10 is prevented from leaking at the connection between the first sound hole 75 and the second sound hole 621. Similarly, the housing 62 is provided with a second rubber ring 64 at the outward end of the third sound hole 622 to enable the first sound hole 75 and the third sound hole 622 to be in sealed communication when the terminal device 70 is located at the second position. The second rubber ring 64 can also function in the same way as the first rubber ring 63.

The first sound hole 75 includes a first sub hole 751 and a second sub hole 752 connected to each other, the first sub hole 751 is relatively close to the display surface 711, the second sub hole 752 is relatively close to the receiving groove 73, a center line of the first sub hole 751 is perpendicular to the display surface 711, and the second sub hole 752 is inclined with respect to the display surface 711 toward the bottom of the terminal device. The first sub-hole 751 is horizontally arranged in the left-right direction, and the second sub-hole 752 is inclined in the up-down direction. The first sound hole 75 includes a first aperture 753 on the side of the display face 711 and a second aperture on the slot bottom wall 731, the first aperture 753 being higher than the second aperture. It is understood that the first aperture 753, i.e., the first sub-hole 751 faces the aperture on the side of the display face 711, and the second aperture, i.e., the second sub-hole 752 faces the aperture on the side of the accommodating groove 73. To further provide the screen duty of the terminal device 70, the display screen 71 is made relatively larger, typically with the first aperture 753 being as close as possible to the edge of the top of the terminal device 70; while the second aperture 754 is at a distance from the top edge of the terminal device 70 to facilitate interfacing with the second sound hole 621 and the third sound hole 622. Therefore, the first sound hole 75 is arranged in the above manner, and the position of the first port 753 is higher than that of the second port 754, so that the screen occupation ratio is ensured, and the receiver 10 and the first sound hole 75 can be better matched, and a better sound transmission effect is obtained.

When the image capturing device 60 is in the first position, the second sound hole 621 is disposed obliquely with respect to the display surface 711, and an included angle between a center line of the second sound hole 621 and a center line of the second sub-hole 752 is greater than or equal to 150 °. This can avoid making the angle between the first sound hole 75 and the second sound hole 621 smaller, which is beneficial to transmit the sound emitted from the receiver 10 from the second sound hole 621 to the first sound hole 75. Similarly, when the image capturing device 60 is in the second position, the third sound hole 622 is disposed obliquely with respect to the display surface 711, and an angle between a center line of the third sound hole 622 and a center line of the second sub-hole 752 is greater than or equal to 150 °.

When the first voice coil 210 is energized with current, the first voice coil 210 can drive the first diaphragm 310 to vibrate under the action of the first magnetic circuit system 100, so as to generate sound, and then the sound is transmitted to the outside of the receiver 10 through the first sound outlet 410. Similarly, when the second voice coil 220 is energized, the second voice coil 220 can drive the second diaphragm 320 to vibrate under the action of the second magnetic circuit system 100, so as to generate sound, and then the sound is transmitted to the outside of the receiver 10 through the second sound outlet 420. Thus, when the receiver 10 needs the side of the first sound outlet 410 to generate sound, the first voice coil 210 can pass through the current to vibrate the first diaphragm 310 to generate sound; when the receiver 10 needs the side of the second sound outlet 420 to generate sound, the second voice coil 220 can pass current to vibrate the second diaphragm 320 to generate sound. Thus, with the above arrangement, it is possible for the receiver 10 to emit sound in two directions. It is understood that current may be simultaneously applied to the first voice coil 210 and the second voice coil 220 to simultaneously vibrate the first diaphragm 310 and the second diaphragm 320.
