The housing 4 has a cavity 11 therein. The housing 4 has a first opening and a second opening, and the first opening and the second opening are respectively provided on different surfaces of the housing 4. Different electronic devices have shells 4 with different structures, and the components of the shells 4 are different, for example, the shells 4 may include a front shell, a rear cover, and a middle frame disposed therebetween, the front shell, the rear cover, and the middle frame together enclose an inner cavity, and the first opening may be disposed on the front shell, the rear shell, or the middle frame; the second opening can be arranged on the front shell, the rear shell and the middle frame, wherein the first opening and the second opening are arranged on different surfaces. For another example, the housing 4 may include a front cover and a rear cover, the front cover and the rear cover together enclose an inner cavity, the first opening may be disposed at the front shell, the rear shell, or an assembly gap between the front cover and the rear cover; the second opening can be arranged at the front shell, the rear shell and the assembly gap of the front cover and the rear cover. Wherein the first opening and the second opening should be provided on different surfaces. Of course, it will be understood by those skilled in the art that the electronic device may further have more openings communicating with the inner cavity, and the openings are disposed on at least two surfaces of the housing 4 to ensure working effects on different surfaces of the electronic device.

Mainboard 8, mainboard 8 set up in the casing 4, mainboard 8 has first through-hole 81, first through-hole 81 with form first passageway 91 between the first opening. Wherein the first channel 91 may be a channel formed between the housing and the middle frame 9. In another embodiment, the first channel may also be a first opening provided on the housing, the first opening communicating with the receiver. The first through hole 81 in the main board 8 may or may not be aligned with the first opening, and those skilled in the art will understand that the first through hole needs to have a communication channel with the first opening.

The telephone receiver assembly comprises a telephone receiver 2 and a telephone receiver support 1, the telephone receiver 2 is arranged on the mainboard 8, the telephone receiver 2 is opposite to the first through hole 81, and the telephone receiver support 1 is provided with a second through hole 12. The receiver 2 can be a one-way sound output receiver or a two-way sound output receiver. The bidirectional sound output receiver can effectively reduce the occupied space of the receiver in the electronic equipment. The one-way sound output telephone receiver is lower in cost. In the embodiments of the present application, a bidirectional speaker/receiver is taken as an example. The receiver support 1 surrounds the receiver to provide protection for the receiver 2. The receiver 2 is opposite to the first through hole 81, so that an outward sound hole gap of the receiver 2 can emit sound through the first through hole 81. It will be appreciated that the receiver 2 is provided on the main board 8 and the receiver support 1 is also provided on the main board 8. A second sound outlet 12 is provided on the receiver holder 1, and the second sound outlet 12 is used for discharging sound through the second sound outlet 12 from the other sound outlet gap of the receiver 2. Usually, the surface of the sound outlet hole of the receiver is also provided with a diaphragm.

The camera assembly 3 is arranged in the second opening, a first gap 5 is formed between the camera assembly 3 and the shell 4, and a second channel is formed between the first gap 5 and the second through hole 12. The camera assembly may be used for a front camera, a rear camera, a depth camera, etc., and the present application is not particularly limited. The camera assembly is arranged in the second opening, so that a larger movement space is provided for the camera assembly under the condition of zooming, and meanwhile, the space occupied by the camera assembly in the electronic equipment can be reduced. The camera module is connected with the shell in an abutting mode, so that the electronic equipment can be prevented from falling out in the using process of a user.

When the receiver 2 is a two-way receiver, the receiver 2 will emit sound from different sound emitting apertures of the receiver during use. The sound signal of the sound transmitted from the first pore is the first sound signal, and the first sound signal is the sound signal output from the first channel; the sound signal transmitted out of the second aperture is a second sound signal, and the second sound signal is a sound signal output from the second channel.

In the case of use of the receiver 2, the first sound signal is in phase opposition to the second sound signal. Therefore, under the condition that the first sound signal is transmitted to the outside of the electronic equipment through the first opening and the second sound signal is transmitted to the outside of the electronic equipment through the second opening, the phases of the first sound signal and the second sound signal are offset, and the effect of silencing is achieved.

To better illustrate that the phases of the first and second sound signals are cancelled out, so as to achieve the silencing effect, an example is given. Since λ is v/f, the propagation speed v of sound in air is 340 m/s, and f is f0, i.e. 400 hz. Where f0 is the resonance frequency of the electronic device when the receiver amplitude is maximum. The wavelength of the sound signal at f0 can be calculated to be 0.85 meter, the distance from the first sound signal of the receiver 2 to the surrounding user is a, and the distance from the second sound signal to the surrounding user is b. The difference a-b between the propagation paths of the first and second sound signals should be much less than 0.85 m so that the effect caused by the difference a-b is negligible, i.e. the propagation paths of the sound signals are not out of phase, so that the first and second sound signals need to be opposite in phase to each other in order to cancel the sound signals.

Specifically, the phase difference between the first sound signal and the second sound signal output by the receiver 2 is an odd multiple of 1/2 wavelengths, and the sounds cancel each other out, so that users around the electronic device cannot hear the content of the call, and the privacy of the users is well protected.

The camera assembly 3 comprises a camera and a decoration ring connected with the camera. The camera is decorated to circle usually around the camera, provides the protective capacities for the camera, prevents at the in-process that electronic equipment used that the camera from falling out. The camera decorative ring and the shell 4 are mutually abutted to form the first gap 5.

Optionally, the decorative ring is provided with a skirt 31, and the skirt 31 is provided with a third through hole 3121. The third through hole 3121 communicates with the second through hole 12, and the third through hole 3121 communicates with the first gap 5 to form the second passage. The third through hole 3121 is provided on a side of the skirt close to the camera, and a side of the skirt away from the camera is bonded to the housing 4. The third through hole 3121 is seted up through decorating the circle and is replaced and set up out the sound hole alone on electronic equipment's casing, can improve electronic equipment's water-proof effects.

A first sealing element 6 is arranged between the second through hole 12 and the third through hole 3121. The first sealing member may be waterproof foam or waterproof silicone, but it is understood by those skilled in the art that the first sealing member may also be other materials having waterproof effect. The present application is not particularly limited. In order to ensure that the sound signal can be transmitted to the outside of the electronic device through the second channel, the first sealing member does not shield the second through hole. In some embodiments, the first seal may overlie the second through hole, but the material selected may be a dust screen or other material having the ability to pass sound.

In some embodiments of the present application, the skirt 31 includes a first connection portion 311 and a second connection portion 312 connected to the first connection portion 311. The second connecting portion 312 is connected to the receiver holder 1, the first connecting portion 311 is connected to the bezel, and the third through hole 3121 is provided in the second connecting portion 312. The first connection portion and the second connection portion are generally perpendicular to each other. Of course, as can be understood by those skilled in the art, the first connection portion and the second connection portion may not be perpendicular to each other, and it is only necessary to ensure that the first connection portion and the second connection portion can enable the camera bezel to be connected to the housing of the electronic device.

Alternatively, the second channel includes a first channel portion formed between the first connection portion 311 and the housing 4 and a second channel portion formed between the second connection portion 312 and the housing 4, the first channel portion and the second channel portion communicating. The first channel portion and the second channel portion may not have the same size. In some embodiments, since the first channel portion is close to the camera, in order to ensure that there is no problem of poor waterproof effect caused by a large gap between the housing 4 and the camera, the first channel portion should be designed to have a small size. The second channel part is close to the telephone receiver, and under the condition that the telephone receiver plays sound, a larger space is beneficial to forming sound cavity resonance, so that the quality of sound signals of the telephone receiver is improved. When the sound signal passes through the first channel part, the first channel part is small in size and can play a role in gathering, so that the volume of the sound signal can be properly increased when the sound signal passes through the first channel part.

In an alternative embodiment, the electronic device further comprises a third sealing member, which is arranged between the second connection portion 312 and the housing 4, and the third sealing member 3122 forms part of the channel wall of the second channel. The third sealing member enables the second connecting portion of the skirt to be connected to the housing, and the second connecting portion is connected to the first connecting portion, so that it can be considered that the bezel of the camera module is connected to the housing. In order to enable the second sound signal to be transmitted out of the electronic device housing through the second channel as much as possible, the remaining channels, where the sound signal may be lost, need to be blocked. The third sealing member 3122 may be used as a blocking member. The third sealing member can effectively prevent the sound signal from being transmitted in the gap between the shell and the receiver support, thereby causing the loss of the sound signal. The material of the third sealing member 3122 may be sealing foam, PET film, or the like. It will be understood by those skilled in the art that the material of the third sealing member 3122 may also be other materials having a low sound-guiding rate, and the present application is not particularly limited. The cotton advantage that has the leakproofness good, quality is little and with low costs of sealed bubble, this application uses the cotton example of sealed bubble.

Optionally, the electronic device further comprises a second sealing member 7, which is disposed between the receiver support 1 and the main board 8. The second sealing member can effectively prevent the sound signal from being transmitted from the gap between the receiver support and the main board, so that the loss of the sound signal is caused. On the other hand, the sealing foam can play a certain waterproof and moistureproof function, and when the electronic equipment receives humid air or water, the sealing foam can form a certain sealing space between the receiver support and the mainboard, so that the electronic devices in the electronic equipment are protected, and the probability of damage is reduced.

In particular, at least a part of the second seal 7 is located between the receiver 2 and the main board 8. It will be understood by those skilled in the art that the second sealing member may be located entirely between the receiver and the motherboard, or only partially between the receiver and the motherboard, and the other part may provide a sealing function for the rest of the electronic devices on the motherboard. The material of the second sealing member 7 may be sealing foam, PET film, or the like. It will be appreciated by those skilled in the art that the material of the second sealing member 7 may also be other materials having a lower sound-guiding rate, and the present application is not particularly limited. The cotton advantage that has the leakproofness good, quality is little and with low costs of sealed bubble, this application uses the cotton example of sealed bubble.

In an alternative embodiment, the camera assembly 3 is provided with a projection 32, the projection 32 at least partially obstructing the first gap 5, the projection 32 being spaced from the housing 4.

In this embodiment, the projection 32 forms a shield directly above the opening of the second channel facing away from the cavity, and a slight opening is formed between the projection and the housing 4, so that the sound signal is guided out of the slight opening. Due to the small size of the opening, liquid can be prevented from entering the interior of the electronic device through the opening in the event that an amount of liquid surrounds the electronic device. The bulge forms to shelter from above the second channel, so that the sight of a user is sheltered from by the bulge under the condition of using the electronic equipment, the user cannot directly notice the second through hole, and the appearance integrity of the electronic equipment is improved. Meanwhile, the bending times of the second channel are increased, and the dustproof and waterproof performance of the second channel is improved. In addition, external pollutants of the electronic equipment are prevented from entering the second channel from the second opening, so that the service life of the sound outlet channel after the sound outlet channel is heightened is prolonged, and the times of maintenance and cleaning are reduced. Bending for many times can restrict more pollutants and get into back sound channel, also can not get into 4 insides and cause the pollution to receiver 2. The safety of the electronic equipment is improved.
