It will be appreciated that terminal 1000 can be a mobile terminal such as a cell phone, a notebook computer, etc., although terminal 1000 can also be a stationary terminal such as a desktop computer, etc.
As shown in fig. 1 to 3, a microphone assembly 100 according to an embodiment of the present invention may include a microphone 1, a shield 2, and a cover 3.
Specifically, the shield case 2 houses the microphone 1. For example, the shielding case 2 is a metal member, the microphone 1 is fixed on and electrically connected to a circuit board (not shown), and the shielding case 2 covers the microphone 1 on the circuit board to play a role of shielding electromagnetic waves, thereby playing a role of preventing interference.
Specifically, as shown in fig. 1 to 3, the shield case 2 is provided with a sound transmission hole 21 penetrating therethrough in the thickness direction thereof, and the diaphragm of the microphone 1 is disposed adjacent to the sound transmission hole 21, for example, the diaphragm of the microphone 1 is disposed adjacent to the sound transmission hole 21 and facing the sound transmission hole 21. Therefore, external sound can be transmitted to the vibrating diaphragm of the microphone 1 through the sound transmission hole 21, so that the sound receiving effect of the microphone 1 is improved.
A connection portion 22 is provided on a side surface (for example, a lower surface shown in fig. 1 to 3) of the shield case 2 remote from the microphone 1, and the connection portion 22 is provided around the sound transmission hole 21.

As shown in fig. 1 to 3, the cover 3 is provided with a sound receiving hole 31, that is, the cover 3 is provided with a sound receiving hole 31 penetrating through the cover in the thickness direction, and the sound receiving hole 31 is arranged opposite to the connecting portion 22. For example, as shown in fig. 1, the center axis of the sound receiving hole 31 and the center axis of the connecting portion 22 are collinear with the center axis of the sound transmitting hole 21. Of course, it is understood that the center line of the sound receiving hole 31 and the center line of the sound transmitting hole 21 may deviate from each other by a certain distance or have an included angle therebetween, so long as the sound receiving hole 31 is guaranteed to be opposite to the connecting portion 22. Thereby, the sound outside the cover 3 can be transmitted to the microphone 1 through the sound receiving hole 31, the connection portion 22, and the sound transmitting hole 21 in this order.
As shown in fig. 1-3, the connection portion 22 extends into the sound receiving hole 31. Thus, the axial direction of the receiving hole 31 is the same as the axial direction of the portion of the connecting portion 22 that extends into the receiving hole 31.
One of the connecting portion 22 and the receiving hole 31 is provided with an annular projection 4 which abuts against the other. That is, the connecting portion 22 extends into the sound receiving hole 31, and when the annular projection 4 is provided on the outer peripheral wall of the connecting portion 22, the annular projection 4 is stopped against the inner peripheral wall of the sound receiving hole 31, and when the annular projection 4 is provided on the inner peripheral wall of the sound receiving hole 31, the annular projection 4 is stopped against the outer peripheral wall of the connecting portion 22. Therefore, the sealing performance between the cover body 3 and the shielding cover 2 is improved, the occurrence of the air leakage problem is avoided, and the shielding cover is simple in structure, convenient to assemble and beneficial to improving the production efficiency.
According to the microphone assembly 100 provided by the embodiment of the invention, the annular bulge 4 is arranged, so that the tightness between the cover body 3 and the shielding cover 2 is improved, the occurrence of the air leakage problem is avoided, the structure is simple, the assembly is convenient, and the production efficiency is improved.
Alternatively, as shown in fig. 1 to 3, the inner peripheral wall of the connecting portion 22 is flush with the side wall of the sound-transmitting aperture 21. Of course, it should be understood that the inner peripheral wall of the connecting portion 22 may not be flush with the side wall of the sound transmission hole 21, for example, the inner diameter of the connecting portion 22 is larger than the inner diameter of the sound transmission hole 21.
In some alternative embodiments of the invention, as shown in fig. 1-7, the outer peripheral wall of the connecting portion 22 is provided with an annular protrusion 4, the annular protrusion 4 abutting against the inner peripheral wall of the sound receiving hole 31. Alternatively, the annular projection 4, the connecting portion 22 and the shield case 2 are integrally formed, whereby simplification of the production process, reduction of the production cost, and improvement of the strength of the annular projection 4 are facilitated.
Alternatively, the annular projection 4 is provided with a guide slope 41 provided on a side of the annular projection 4 remote from the shield case 2, the guide slope 41 extending in a direction from the shield case 2 to the cover 3 toward a direction remote from the inner peripheral wall of the sound receiving hole 31. So that the guide slope 41 can serve as a guide when the connection portion 22 is inserted into the sound receiving hole 31.
Of course, in other alternative examples, the annular protrusion 4 is provided on the inner peripheral wall of the sound receiving hole 31, the annular protrusion 4 is stopped against the outer peripheral wall of the connecting portion 22, and the annular protrusion 4 and the cover 3 are integrally formed. Further, the annular projection 4 has a guide slope provided on a side of the annular projection adjacent to the shield case 2, the guide slope extending toward the distal connection portion 22 in a direction from the cover 3 to the shield case 2.
Further, referring to fig. 2, in a direction from the shield case 2 to the cover 3, the wall thickness of the connection portion 22 is gradually reduced, and the annular projection 4 is provided at an end of the connection portion 22 remote from the shield case 2. For example, as shown in fig. 2, the wall thickness of the connecting portion 22 gradually decreases in the top-to-bottom direction, and the annular projection 4 is provided at the lower end of the outer peripheral wall of the connecting portion 22. Thus, not only is the insertion of the connecting portion 22 into the sound receiving hole 31 facilitated for assembly, but also the elastic deformability of the annular projection 4 is facilitated to be improved, thereby improving the sealability.
In some alternative embodiments of the present invention, the annular protrusions 4 are plural, and the plural annular protrusions 4 are disposed at intervals in the axial direction of the sound receiving hole 31. For example, a plurality of annular projections 4 are provided on the outer peripheral wall of the connecting portion 22, the plurality of annular projections 4 are disposed at intervals in the axial direction of the sound receiving hole 31, and each annular projection 4 abuts against the inner peripheral wall of the sound receiving hole 31. For another example, a plurality of annular protrusions 4 are provided on the inner peripheral wall of the sound receiving hole 31, the plurality of annular protrusions 4 are provided at intervals in the axial direction of the sound receiving hole 31, and each annular protrusion 4 abuts against the outer peripheral wall of the connecting portion 22. Thereby, it is advantageous to realize multi-layer sealing, thereby improving the sealing effect.
According to some alternative embodiments of the invention, as shown in fig. 4, the annular protrusion 4 extends in a zigzag shape in the circumferential direction of the sound receiving hole 31. That is, the annular projection 4 extends in a zigzag manner in the entire circumferential direction of the sound receiving hole 31. For example, as shown in fig. 4, when the annular projection 4 is provided on the outer peripheral wall of the connecting portion 22, since the circumferential direction of the portion of the connecting portion 22 located in the sound receiving hole 31 is the same as the circumferential direction of the sound receiving hole 31, the annular projection 4 extends in a zigzag shape in the entire circumferential direction of the connecting portion 22. For another example, when the annular projection 4 is provided on the inner peripheral wall of the sound receiving hole 31, the annular projection 4 extends in a zigzag manner in the entire circumferential direction of the sound receiving hole 31.
In other embodiments, as shown in fig. 5, the annular projection 4 extends in a wavy manner in the circumferential direction of the sound receiving hole 31. Alternatively, in other embodiments, as shown in fig. 6, the annular projection 4 is formed by arranging a plurality of sequentially connected n-shaped structures in the circumferential direction of the sound receiving hole 31.
Of course, the annular projection 4 may have other extending shapes, for example, as shown in fig. 7, in the circumferential direction of the sound receiving hole 31, the annular projection 4 extends linearly as long as it can be ensured that the annular projection 4 is always located between the connecting portion 22 and the sound receiving hole 31 and plays a sealing role in the entire circumferential direction of the sound receiving hole 31.
According to some embodiments of the present invention, as shown in fig. 7, the central axis of the annular protrusion 4 and the central axis of the sound receiving hole 31 form an angle therebetween, in other words, the central axis of the annular protrusion 4 and the central axis of the portion of the connecting portion 22 located in the sound receiving hole 31 form an angle therebetween, that is, the annular protrusion 4 is disposed obliquely with respect to the cross section of the sound receiving hole 31 and the cross section of the portion of the connecting portion 22 located in the sound receiving hole 31. For example, as shown in fig. 7, the annular protrusion 4 is provided on the outer peripheral wall of the connecting portion 22, a is the central axis of the annular protrusion 4, b is the central axis of the portion of the connecting portion 22 located in the sound receiving hole 31, and the angle between a and b is c, and c satisfies: c is more than 0 and less than 90 degrees. Thus, the structure is simple.
In some embodiments of the invention, as shown in fig. 3, the portion of the connection portion 22 located within the sound receiving hole 31 minus the portion of the connection portion 22 corresponding to the annular projection 4 is referred to as a connection segment. That is, the portion of the connecting portion 22 located in the sound receiving hole 31, from which the portion of the connecting portion 22 corresponding to the annular projection 4 is removed, has the remaining portion as a connecting section, and the foam 5 is provided between the connecting section and the inner peripheral wall of the sound receiving hole 31. Therefore, the sealing effect is improved, and the sealing effect is further improved.
According to some embodiments of the invention, the annular projection 4 is a rubber or silicone piece. For example, when the annular projection 4 is provided on the above-described connection portion 22, a groove is provided on the outer peripheral wall of the connection portion 22, and the annular projection 4 is sleeved on the connection portion 22 and is restrained in the groove, thereby preventing displacement of the annular projection 4 during installation.
