Referring to fig. 3, fig. 3 is a schematic diagram illustrating a split of an electronic device according to an embodiment of the present disclosure. The housing 140 of the electronic device 100 has a first receiving cavity such as first receiving cavity 142 and a second receiving cavity such as second receiving cavity 144. The volume of the first receiving chamber 142 is smaller than the volume of the second receiving chamber 144. The first receiving cavity 142 is formed by one end of the housing 140 being recessed toward the inside of the housing 140, or the first receiving cavity 142 penetrates one end of the housing 140. Wherein the telescoping device 120 is positionable within the first receiving cavity 142 and slidable within the first receiving cavity 142 to effect a switch between a retracted state and an extended state. Wherein a circuit board 180, a battery, etc. of the electronic device 100 may be disposed in the second receiving cavity 144.

It can be understood that, when a user needs to take a picture, the retractable device 120 can be pushed out from the first receiving cavity 142 and be extended. When the user does not need to take a picture, the retractable device 120 can be accommodated in the first accommodating cavity 142 and forms a retracted state.

The receiver 122 has a limited volume in the rear cavity because it is limited by the first receiving cavity 142 during the process of transmitting sound. In some embodiments, the applicant of the present application extends the back cavity of the receiver 122 to the outside of the electronic device 100, and communicates with the outside air, so as to increase the effective back cavity volume of the receiver, and improve the audio performance of the receiver 122. That is, the edge position of one end of the housing 140 is set to be in a leakage state, or a small hole or a gap is left on the surface position of the telescopic device 120 to be communicated with the outside air, so that the receiver 122 can also use a part of the space outside the electronic device 100 as a back cavity, thereby increasing the effective back cavity volume of the receiver 122 and improving the audio performance of the receiver 122.

However, the front and back cavities of the receiver 122 are all conducted to the outside air, and the phases of the sound waves in the front and back cavities are opposite, which easily causes the problem of short circuit, resulting in poor audio performance. And foreign substances are liable to enter the electronic apparatus 100.

Based on this, in the embodiment of the present application, the back cavity acoustic wave, that is, the acoustic wave generated by the back surface of the vibrating diaphragm of the receiver 122, is conducted into the casing 140, the cavity (the second receiving cavity 144) in the casing 140 of the electronic device 100 is used to expand the back cavity, and the whole cavity (the second receiving cavity 144) in the casing 140 is isolated from the outside, so that there is no problem of short circuit with the front cavity acoustic wave, that is, the acoustic wave generated by the front surface of the vibrating diaphragm of the receiver 122. Meanwhile, a leakage position does not need to be arranged on the shell 140, and the possibility that foreign matters enter the electronic equipment 100 is reduced.

As shown in fig. 3, the housing 140 is provided with a first through hole 146, the first through hole 146 is formed at a bottom position of the first receiving chamber 142, and the first receiving chamber 142 and the second receiving chamber 144 are communicated through the first through hole 146. So that the sound emitted from the receiver 122 can be transmitted to the second receiving chamber 144 through the first through hole 146 and transmitted to the outside of the electronic device 100 through the housing 140.

Referring to fig. 4, fig. 4 is a schematic exploded view of a telescopic device according to an embodiment of the present disclosure. The telescopic device 120 may further include a face case 121, a bottom case 123, a decoration 125, a receiver pad 127, and a gasket 128.

The second through hole 1212 may communicate with the first receiving groove 1214 for placing the receiver 122, and the receiver 122 may transmit the sound signal directly through the second through hole 1212. The receiver 122 can transmit the sound signal thereof to the second receiving cavity 144 through the second through hole 1212 and the first through hole 146, so as to transmit the sound through the housing 140.

To increase the effect of communication between the first through hole 146 and the second through hole 1212. A gasket 128 is arranged between the telescopic device 120 and the shell 140, the gasket 128 is made of flexible materials, and the gasket 128 can deform under pressure. The shim 128 is disposed around the first through hole 146 and the second through hole 1212. When the telescopic device 120 is received in the first receiving cavity 142, the telescopic device 120 may press the gasket 128 to deform the gasket 128, thereby sealing the first through hole 146 and the second through hole 1212. Thereby preventing the sound wave from spreading.

In some embodiments, the gasket 128 is secured at one end within the first receiving cavity 144, or the gasket 128 is secured to the bottom of the first receiving cavity 144, such as by gluing. The gasket 128 is disposed around the first through hole 146. The telescopic device 120 is provided with a placement groove 1211, the placement groove 1211 is formed around the second through hole 1212, and the other end of the gasket 128 is received in the placement groove 1211. The positioning groove 1211 is used to limit the gasket 128.

It should be noted that one end of the spacer 128 may also be fixed to the retractor 120, such as by gluing. The shim 128 is disposed around the second through hole 1212. The placement groove is provided on the housing 140, or the placement groove is provided at the bottom of the first receiving groove and is provided around the first through hole 146, and the gasket 128 can be received in the placement groove on the housing 140.
