Description
Technical Field
The invention relates to the technical field of mobile terminals, in particular to a terminal sound inlet and outlet structure and a mobile terminal.
Background
The microphone of the mobile phone is used as an input source of the mobile phone to provide a function of recording sound, and the loudspeaker is used as an output structure of the sound to provide a function of outputting the sound. The loudspeaker and the microphone are located on a mainboard of the mobile phone and are sealed inside the mobile phone shell, so that a small hole needs to be formed in the position, opposite to the microphone, of the mobile phone shell, external sound can enter the microphone through the small hole, internal sound can be transmitted out of the mobile phone, and the small hole is called a microphone in-out sound hole.
Taking the microphone sound entering design as an example, when the microphone sound entering is considered, the sealing performance of the microphone needs to be considered, that is, the sound entering range of the microphone cannot be too large, which is a situation that sound inside a mobile phone easily enters the microphone, and this is not desired by designers in the microphone sealing performance design.
In combination with the above two considerations, the existing microphone sound inlet hole design adopts a small hole formed on the casing at the position opposite to the microphone, so that the sound inlet is ensured to be normal and the sealing property is ensured. However, this design has a major drawback that once the microphone sound inlet hole is blocked for some reason, the sound cannot be recorded, thereby affecting the functions of the mobile phone, such as communication, recording, etc. For example, when a user holds the mobile phone, a holding gesture that the fingers block the sound inlet hole may occur, and most commonly, the mobile phone is held by the small finger from the bottom of the mobile phone when the user makes a call, and the position of the mobile phone is just held at the sound inlet hole of the microphone. In this case, the microphones cannot record sound, and particularly in the process of calling, due to the existence of the dual-microphone noise reduction algorithm, if one of the two microphones does not record sound, the phenomenon of no sound in the upstream of the calling occurs, namely, the opposite party cannot hear the sound; similarly, there is a case where the microphone sound inlet hole is blocked by a foreign substance, and the effect of this case is the same as the above case.

Wherein the decoration hole 5 and the sound inlet hole 1 are separated by the isolation baffle 2, and the sound inlet hole 1 and the decoration hole 6 are separated by the isolation baffle 3. Keep apart separation blade 2 and keep apart separation blade 3 and be in the enclosed condition under the same circumstances of both ends atmospheric pressure, when keeping apart separation blade 2 or keep apart the atmospheric pressure in separation blade 3 both sides different, then because the atmospheric pressure is poor, keep apart the separation blade and can open towards one side that atmospheric pressure is low.
The sound inlet hole 1, the decorative hole 5 and the decorative hole 6 are not blocked, and when a person speaks, the air pressures on the left side and the right side of the isolation blocking piece 2 and the isolation blocking piece 3 are equal, so that the isolation blocking piece 2 and the isolation blocking piece 3 are in a closed state, and sound can enter from the sound inlet hole 1.
The sound inlet hole 1 is blocked, the decorative holes 5 and 6 are not blocked, when a person speaks, the air pressure on the left side of the isolation blocking piece 2 is larger than the air pressure on the right side (because the sound inlet hole 1 is not fed, and the decorative holes 5 are fed), and the isolation blocking piece 2 is opened towards the sound inlet hole 1.
The decorative hole 6 is blocked, when a person speaks, the air pressure at two sides of the isolation blocking piece 2 is the same, and the isolation blocking piece 2 is in a closed state; the air pressure at the left side of the isolation separation blade 3 is larger than the air pressure at the right side, and the isolation separation blade 3 is opened towards the right side. Since only the sound inlet hole 1 is facing the microphone, the opening of the isolating shutter 3 does not affect the sound inlet hole 1.
As shown in fig. 5, the isolation barrier includes an upper barrier 21 and a lower barrier 22, the upper barrier 21 and the lower barrier 22 are connected by a film 23, the upper barrier 21 is adhered to the inner wall of the outer shell or the outer wall of the inner shell, and the lower barrier 22 is bent along the film 23 relative to the upper barrier 21 under atmospheric pressure, so that an airflow channel is formed between the lower barrier 22 and the outer wall of the inner shell or the inner wall of the outer shell.
As another optional structure, the isolation blocking piece comprises an upper blocking piece and a lower blocking piece, the upper blocking piece is hinged to the lower blocking piece, the upper blocking piece is bonded to the inner wall of the outer shell or the outer wall of the inner shell, and the lower blocking piece rotates relative to the upper blocking piece along the hinge under atmospheric pressure, so that an airflow channel is formed between the lower blocking piece and the outer wall of the inner shell or the inner wall of the outer shell to communicate with the hole adjacent to the sound inlet hole.
The terminal business turn over sound structure that this embodiment was realized sets up the isolation separation blade through the both sides at the sound inlet hole or go out the sound hole, and the first half of isolation separation blade is fixed, and lower half and first half folding joint when the sound inlet hole is blocked, and the latter half of isolation separation blade is opened under the atmospheric pressure effect, advances the sound from other decoration holes on sound inlet hole next door, therefore the sound inlet hole is blockked the problem that influences the sound effect and can be solved by user or foreign object.
