Description

Terminal sound inlet and outlet structure and mobile terminal

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.

While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.

Claims

1. A terminal sound inlet and outlet structure comprises an inner shell and an outer shell, wherein the inner shell is arranged in the outer shell, and the outer wall of the inner shell is tightly attached to the inner wall of the outer shell; the edges of the inner shell and the outer shell are provided with a row of openings, the positions of the openings on the edges of the inner shell and the outer shell correspond to each other, the row of openings at least comprises 3 openings, and a microphone is placed in one opening; the method is characterized in that: an isolation baffle is arranged between the open pore for placing the microphone and the open pores on the two sides of the open pore, the periphery of the isolation baffle is in sealing contact with the outer wall of the inner shell and the inner wall of the outer shell respectively, and when atmospheric pressure difference is formed between the open pore for placing the microphone and the adjacent pore, the isolation baffle is extruded by atmosphere and forms an airflow channel with 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.

2. A terminal sound inlet and outlet structure according to claim 1, characterized in that: the isolation baffle is made of leather.

3. A terminal sound inlet and outlet structure according to claim 1, characterized in that: the isolation separation blade is a metal sheet with the thickness less than 0.5 mm.

4. A terminal sound inlet and outlet structure according to claim 1, characterized in that: the isolation blocking piece is a flexible plastic piece.

5. A terminal in-out sound structure according to any one of claims 1-4, characterized in that: the sealing strips are wrapped around the isolation separation blades, the sealing strips on one side of the isolation separation blades are fixedly bonded with the inner wall of the outer shell or the outer wall of the inner shell, and the isolation separation blades are deformed and distorted under atmospheric pressure and form airflow channels with the outer wall of the inner shell or the inner wall of the outer shell.

6. A terminal in-out sound structure according to claim 3 or 4, characterized in that: the isolation blocking piece comprises an upper blocking piece and a lower blocking piece, the upper blocking piece is connected with the lower blocking piece through a film, the upper blocking piece is bonded with the inner wall of the outer shell or the outer wall of the inner shell, and the lower blocking piece is bent along the film relative to the upper blocking piece 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 the sound inlet hole and the hole adjacent to the sound inlet hole.

7. A terminal in-out sound structure according to claim 3 or 4, characterized in that: 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 a 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 the sound inlet hole and the hole adjacent to the sound inlet hole.

8. A terminal sound inlet and outlet structure according to claim 1, characterized in that: a groove is formed in the bottom edge of the inner shell, and the row of holes are formed in the groove.

9. A terminal sound inlet and outlet structure according to claim 1, characterized in that: the bottom edge of the inner shell is provided with another row of holes, and the inner sides of the holes are provided with loudspeakers.

10. A mobile terminal, characterized in that the mobile terminal is provided with a terminal in-out sound structure according to any one of claims 1-9.
