An electronic device according to an embodiment of the application is described below in conjunction with fig. 1-3.

As shown in fig. 1, there is provided according to some embodiments of the present application an electronic device, including:

a middle frame 1, a microphone 2 and a decorative sheet 3.

The middle frame 1 is provided with an assembling groove 11, the assembling groove 11 is used for arranging the decorative sheet 3, the bottom surface of the assembling groove 11 comprises a first platform and a second platform, the first platform protrudes out of the second platform in a first direction, the first direction can be the direction from the bottom surface of the assembling groove 11 to the notch of the assembling groove 11, namely the bottom surface of the assembling groove 11 is step-shaped, and the first platform is higher than the second platform.

The microphone 2 is arranged in the middle frame 1, and the microphone 2 is used for picking up an audio signal outside the electronic equipment; the decorative sheet 3 is arranged in the assembling groove 11 and attached to the first platform, a first gap 8 is formed between the decorative sheet 3 and the second platform, and a second gap 9 is formed between the decorative sheet 3 and the side wall of the assembling groove 11. External sound signals of the electronic device can sequentially pass through at least part of the second gap 9, the first gap 8 and the inner part of the middle frame 1 and are finally transmitted to the sound receiving side of the microphone 2, so that a sound guide channel is formed between the sound receiving side of the microphone 2 and at least part of the second gap 9, namely the sound guide channel comprises the sound receiving side space of the microphone 2, the first gap 8 and at least part of the second gap 9.

Specifically, referring to fig. 2 and 3, the second gap 9 may be a gap formed between the peripheral side of the decorative sheet 3 and the peripheral side wall of the fitting groove 11 when the second gap 9 is an annular gap. In addition, the second gap 9 may be a partial gap formed between the decorative sheet 3 and a first sidewall of the mounting groove 11, the first sidewall being a sidewall of the mounting groove 11 close to the second platform, in which case the second gap 9 may be only a gap on the decorative sheet 3 side, and the same effect of sound transmission may be achieved.

The electronic device provided by the embodiment of the application forms a sound guide channel between the sound receiving side of the microphone 2 and at least part of the second gap 9 by arranging the first gap 8 at the bottom side of the decorative sheet 3 and forming the second gap 9 at the side surface of the decorative sheet 3. On the basis of ensuring the normal sound reception of the microphone 2 of the electronic equipment, the surface of the decorating part 3 is prevented from being provided with holes, and the appearance integrity of the electronic equipment is ensured.

Optionally, referring to fig. 1, the sound guiding channel further includes a third gap 10, and the third gap 10 is located in the middle frame 1 and communicates the sound receiving side of the microphone 2 and the first gap 8.

Specifically, since the microphone 2 is disposed in the middle frame 1, when the microphone 2 picks up an audio signal outside the electronic device, the audio signal outside the electronic device needs to pass through the second gap 9 and the first gap 8 first, and then pass through the third gap 10 in the middle frame 1 to the sound receiving side of the microphone 2. The third gap 10 improves the smoothness of the sound guide channel, and ensures the normal sound reception of the microphone 2.

Alternatively, referring to fig. 1, the third gap 10 is located in the orthographic projection of the decorative sheet 3 on the middle frame 1.

Specifically, since the microphone 2 is disposed in the middle frame 1, after the external sound signal of the electronic device passes through the second gap 9 and the first gap 8 in sequence, the external sound signal needs to be transmitted to the microphone 2 through the third gap 10 located in the middle frame 1. Since the second gap 9 is disposed between the decorative sheet 3 and the sidewall of the assembling groove 11, when the third gap 10 is located in the orthographic projection of the decorative sheet 3 on the middle frame 1, that is, the first gap 8 changes the sound guiding direction of the sound guiding channel, the third gap 10 and the second gap 9 may be disposed in a staggered manner, at this time, when looking from the outside to the inside of the electronic device along the second gap 9, only the solid structure of the middle frame 1 can be seen, and the devices inside the middle frame 1 cannot be seen, so that on one hand, the appearance consistency of the electronic device is ensured, and on the other hand, the interference of the impurities entering from the second gap 9 on the devices inside the middle frame 1 is avoided.

Alternatively, the width of said first gap 8, see fig. 1, ranges from 0.1 to 0.5mm, preferably from 0.2 to 0.4 mm.

Specifically, the first gap 8 may be understood as a distance between the decorative sheet 3 and the second platform, and when the decorative sheet 3 is attached to the first platform, a part of the bottom surface of the decorative sheet 3 may be specifically bonded to the first platform, and the remaining part of the bottom surface of the decorative sheet 3 is suspended above the second platform to form the first gap 8, so as to ensure that the sound guide channel of the microphone 2 is unobstructed. When the width of the first gap 8 is too small, the smoothness of sound when the microphone 2 picks up sound may be affected; because the decorative sheet 3 is suspended on the second platform to form a cantilever structure, when the width of the first gap 8 is too large, the stability of assembling the decorative sheet 3 is affected, and the service life of the decorative sheet 3 is reduced.

Alternatively, referring to fig. 1 and 3, the width of the second gap 9 ranges from 0.05 to 0.3mm, preferably from 0.1 to 0.2 mm.

Specifically, the second gap 9 may be understood as a distance between the decorative sheet 3 and a sidewall of the mounting groove 11, and when the decorative sheet 3 is disposed in the mounting groove 11, in order to ensure the mounting efficiency of the decorative sheet 3, it is generally necessary to leave a mounting gap between the decorative sheet 3 and the sidewall of the mounting groove 11, and the present application uses this mounting gap as the second gap 9 to ensure the smoothness of the sound guide channel of the microphone 2. When the width of the second gap 9 is too small, the size of the decorative sheet 3 may be larger than the size of the assembling groove 11 due to an error in the size of the decorative sheet 3, which causes waste of the decorative sheet 3 and reduces the assembling efficiency of the electronic device; when the width of the second gap 9 is too large, on one hand, it is inconvenient to stably install the decoration sheet 3, and on the other hand, too much foreign substances may enter the middle frame 1 from the second gap 9, which may affect the stable operation of the devices in the middle frame 1.

Alternatively, referring to fig. 1 and 2, the fitting groove 11 is provided at the top of the middle frame 1.

Specifically, since the assembling groove 11 is used for arranging the decorative sheet 3, when the assembling groove 11 is arranged at the top of the middle frame 1, the second gap 9 formed between the decorative sheet 3 and the side wall of the assembling groove 11 can be also located at the top of the middle frame 1, which is beneficial to the microphone 2 to collect more noise, further filter the noise and ensure the sound receiving quality of the microphone 2; on the other hand, the appearance integrity of the electronic equipment can be improved, and the appearance attractiveness of the electronic equipment is ensured.

Optionally, referring to fig. 1, the electronic device further includes a circuit board 4, the circuit board 4 is fixed in the middle frame 1, the sound receiving side of the microphone 2 is connected to the circuit board 4, and the circuit board 4 is provided with a sound receiving hole 41 communicated with the sound guide channel.

Specifically, the microphone 2, as an energy conversion device that converts a sound signal input from the outside of the electronic apparatus into an electric signal, may be electrically connected to the circuit board 4 and control the energy conversion thereof by the circuit board 4. The sound receiving hole 41 can be used as a part of the sound guide channel, so that the interference of the circuit board 4 to the sound receiving of the microphone 2 is avoided, and the sound receiving effect of the microphone 2 is ensured.

Optionally, referring to fig. 1, the electronic device further includes a protective layer 5, and the protective layer 5 is disposed between the circuit board 4 and the middle frame 1 and at least partially opposite to the acoustic hole 41.

Specifically, under the condition that the microphone 2 is electrically connected to the circuit board 4, the circuit board 4 needs to complete energy conversion control of the microphone 2 through a control chip on the circuit board 4, and a clean operating environment plays a key role in stable operation of the control chip. The protective layer 5 can well protect the sound receiving hole 41, and the protective layer 5 can be provided with a pore structure, so that the circuit board 4 and the microphone 2 can be clean in operating environment on the basis of not influencing the sound receiving effect of the microphone 2.

Specifically, the protective layer 5 may include at least one of a waterproof film and a dustproof mesh, the waterproof film may be a PI film, a PE film, a PVC film, or the like, and the waterproof film has a micro hole, so that external water may be prevented from flowing into the protective layer without affecting the sound reception of the microphone 2. The dust screen can be a PTFE dust screen, and micron-scale or even nano-scale pore channels can be arranged on the dust screen so as to achieve a good dust-proof effect. In addition, a sealing ring, such as a silica gel sealing ring or a foam sealing ring, can be arranged between the circuit board 4 and the middle frame 1 to ensure the sealing performance of the sound guide channel.

Optionally, referring to fig. 1, the electronic device further includes a screen 6, and the screen 6 is disposed on one side of the middle frame 1 in a covering manner. Specifically, one side of the middle frame 1 may be provided with a groove for facilitating the setting of the screen 6, and the screen 6 may be sealed and fixed in the groove through foam, and electrically connected to the circuit board 4, so as to ensure stable display of the screen 6.

Optionally, referring to fig. 1, the electronic device further includes a sealing cover 7, the sealing cover 7 is disposed in the middle frame 1 and is opposite to the sound receiving side of the microphone 2, and at least a part of the sound guide channel is formed between the sealing cover 7 and the microphone 2. The sealing cover 7 can protect the microphone 2 and the circuit board 4 on the one hand, and can ensure the sealing performance of the sound guide channel on the other hand, for example, the sealing cover 7 in fig. 1 is arranged, so that the sound signals in the sound guide channel are prevented from leaking from the gap between the screen 6 and the middle frame 1.

Optionally, the electronic device includes, but is not limited to, one of a smart watch, a cell phone, a tablet, an e-book reader, an MP3 player, an MP4 player, a computer, a set-top box, a smart television, and a wearable device.
