The shape and size of the receiving groove 110a can be customized according to the shape and size of the microphone 120 to increase the applicable range of the microphone assembly structure 100. The number of the accommodating grooves 110a may be one or more, the number of the microphones 120 and the number of the pressing elements 130 are the same as the number of the accommodating grooves 110a, and when the number of the accommodating grooves 110a is more, each pressing element 130 elastically presses the corresponding microphone 120, so that the sound emitting surface 123a of each microphone 120 presses against the sound emitting side 110b of the corresponding accommodating groove 110a, which is not specifically limited herein.

The microphone 120 is accommodated in the accommodating groove 110 a. Specifically, referring to fig. 5 and 6, the microphone 120 includes a mounting plate 121, a microphone body 122, and an elastic sleeve 123, where the mounting plate 121 is a metal plate to enhance the structural strength of the microphone 120, the mounting plate 121 is connected to the microphone body 122, the elastic sleeve 123 is sleeved on the microphone body 122 and covers one side of the microphone body 122 opposite to the mounting plate 121, a sound emitting surface 123a is formed on one side of the elastic sleeve 123 away from the mounting plate 121, the sound emitting surface 123a is provided with a sound passing hole 123b opposite to the sound emitting hole 110c, and the sound passing hole 123b is also opposite to the sound emitting position of the microphone body 122.

The number of the microphone bodies 122 may be one or more, the number of the elastic sleeves 123 is the same as that of the microphone bodies 122, and fig. 1 shows a case where the number of the microphone bodies 122 is two. The material of the elastic sleeve 123 can be various, and the material of the elastic sleeve 123 can be other elastic materials such as silicone rubber, etc., which is not limited herein.

The pressing element 130 is at least partially elastic and is mounted on the housing 110, and the pressing element 130 is used for elastically pressing the microphone 120, so that the sound emitting surface 123a of the microphone 120 presses against the sound emitting side 110b. Obviously, the pressing element 130 is configured to elastically press against a side of the mounting plate 121 of the microphone 120 opposite to the microphone body 122, and thus, by virtue of the structural strength of the mounting plate 121, the microphone 120 is ensured not to be damaged when the pressing element 130 acts on the microphone 120 for a long time.

There are various ways of providing the pressing member 130 with elasticity at least partially, the pressing member 130 may be elastic at the middle part, and the pressing member 130 may also be elastic at the position connected with the housing 110. Preferably, the entire pressing member 130 has elasticity, so that the pressing member 130 can be elastically deformed.

The material of the pressing member 130 can be various, the material of the pressing member 130 can be set by referring to the material of the elastic sleeve 123, and the material of the pressing member 130 can also be elastic metal, such as spring steel, beryllium copper alloy, and the like, and is not limited specifically herein. The number of the pressing members 130 may be one or more, the number of the pressing members 130 is the same as the number of the microphone bodies 122, and when the number of the pressing members 130 is multiple, each pressing member 130 elastically presses the position of the mounting plate 121 opposite to the corresponding microphone body 122, so as to ensure the sealing property of the sound outlet surface 123a of each elastic sleeve 123.

Through the above technical solution, when the microphone 120 is mounted to the housing 110, firstly, an acting force away from the sound-emitting side 110b is applied to the pressing member 130, and the pressing member 130 is elastically deformed, so that the pressing member 130 is spaced from the microphone 120 in the process of inserting the microphone 120 into the accommodating groove 110 a; then, the microphone 120 is inserted into the receiving groove 110a from the notch of the receiving groove 110 a; then, the biasing force applied to the biasing member 130 is released, and the biasing member 130 springs back to elastically bias the microphone 120 by its own resilient force, so that the sound emitting surface 123a of the microphone 120 is biased against the sound emitting side 110b. With the arrangement, the sealing performance of the sound outlet surface 123a of the microphone 120 can be ensured, and the sound outlet hole 110c can be effectively prevented from being blocked, so that the sound outlet effect of the microphone 120 is ensured.

When the microphone 120 is detached from the housing 110, first, an acting force away from the sound-emitting side 110b is applied to the pressing member 130, and the pressing member 130 is elastically deformed so that the pressing member 130 is spaced apart from the microphone 120; then, the microphone 120 is pulled out from the accommodating groove 110a, so that the microphone 120 can be detached. With this arrangement, it is possible to prevent the microphone 120 and the pressing member 130 from being worn when the microphone 120 is detached.

Referring to fig. 2 and fig. 4, it can be understood that the pressing member 130 may be located on a side of the receiving groove 110a away from the sound outlet 110c, the pressing member 130 may also be located between a groove wall of the receiving groove 110a facing the sound outlet 110c and partially bent to a side of the receiving groove 110a away from the sound outlet 110c, and the pressing member 130 may also be located on the same side of the receiving groove 110a as the sound outlet 110c and partially bent to a side of the receiving groove 110a away from the sound outlet 110c, however, compared with the pressing member 130 located at other positions and partially bent to a side of the receiving groove 110a away from the sound outlet 110c, the pressing member 130 located on a side of the receiving groove 110a away from the sound outlet 110c can simplify the structure of the pressing member 130, and facilitate the pressing of the pressing member 130 to elastically the pressing microphone 120. In view of this, in an embodiment of the present invention, the pressing element 130 is located on a side of the receiving groove 110a far away from the sound outlet 110c.

Referring to fig. 2, it is considered that if the pressing element 130 is mounted on the surface of the housing 110 adjacent to the notch of the receiving cavity 110a, the mounting plate 121 partially extends from the receiving cavity 110a for the pressing element 130 to elastically press, so that the pressing element 130 is protruded from the housing 110, resulting in a larger size of the microphone assembly structure 100 and being disadvantageous to the integration of the pressing element 130 in the housing 110. In view of this, in order to integrate the pressing element 130 into the casing 110, in an embodiment of the present invention, the casing 110 forms the yielding opening 110d and the pressing element 130 at a position where the receiving groove 110a faces the groove wall of the sound hole 110c, and the pressing element 130 is located in the yielding opening 110 d. In this way, the pressing member 130 can be integrated with the housing 110 while reducing the size of the microphone assembly structure 100, and the pressing member 130 and the housing 110 can be integrated with each other.

Specifically, the yielding opening 110d is disposed through a side of the notch close to the accommodating groove 110a, so as to apply an acting force to the pressing member 130, so that the pressing member 130 is elastically deformed. And the two opposite side walls of the abdicating opening 110d are spaced from the pressing part 130, so that the fingers can be more conveniently extended into the abdicating opening 110d to apply an acting force to the pressing part 130.

It should be noted that, when the pressing element 130 is provided in plural, the yielding opening 110d may be one, plural pressing elements 130 are located in the same yielding opening 110d, the yielding opening 110d may also be plural, and each pressing element 130 is located in the corresponding yielding opening 110d, which is not limited herein.

In other embodiments, the pressing element 130 may also be a separately provided structural element and is installed in the abdicating opening 110d, and in this case, the installation manner of the pressing element 130 may be other installation manners such as welding, bonding, clamping, fastening, and the like, which is not limited herein.

Referring to fig. 2 and 4, there are many types of the pressing member 130, in an embodiment of the present invention, the pressing member 130 includes a fixing section 131, a pressing section 132, and a force-bearing section 133 connected in sequence; the end of the fixing section 131 far from the abutting section 132 is connected to the housing 110, the abutting section 132 protrudes toward the sound outlet hole 110c and is disposed in an arc shape, so that the abutting section 132 exceeds the fixing section 131 and the stressed section 133 in the direction close to the sound outlet hole 110c, and one side of the abutting section 132 close to the sound outlet hole 110c is used for elastically abutting against the microphone 120, so that the sound outlet face 123a of the microphone 120 abuts against the sound outlet side 110b. With such an arrangement, on one hand, the elastic pressing strength of the pressing member 130 against the microphone 120 can be ensured; it is also convenient to space the force-bearing segment 133 from the microphone 120 to facilitate the application of force to the force-bearing segment 133.

Specifically, the fixing section 131, the abutting section 132 and the force-bearing section 133 are sequentially arranged along the direction from the groove bottom to the notch of the accommodating groove 110a, so that the operation of the pressing member 130 is facilitated. In other embodiments, the fixing section 131, the abutting section 132 and the force-bearing section 133 may also be sequentially disposed along a direction parallel to the bottom of the receiving groove 110 a.

Moreover, the length of the abutting section 132 in the axial direction of the sound outlet hole 110c is equal to the length of the stressed section 133 in the axial direction of the sound outlet hole 110c, and the length of the abutting section 132 in the axial direction of the sound outlet hole 110c is also greater than the length of the fixing section 131 in the axial direction of the sound outlet hole 110c, so that the connecting position of the abutting piece 130 and the casing 110 is thin, and the abutting piece 130 is convenient to elastically deform under the action of an external force. The difference between the axial length of the abutting section 132 in the sound outlet hole 110c and the axial length of the fixing section 131 in the sound outlet hole 110c may be other length values such as 0.05mm, 0.1mm, and the like.

In other embodiments, the pressing element 130 may also be provided with other elastic elements such as a spring, an elastic arm, and the like.

Referring to fig. 2 and 4, in order to enhance the elastic pressing strength of the pressing member 130 against the microphone 120, in an embodiment of the present invention, the pressing member 130 has a pressing portion 130a for elastically pressing the microphone 120; when the pressing member 130 is in a natural state, a projection of the pressing member 130a in a direction from the notch of the accommodating groove 110a to the groove bottom is located in the groove bottom of the accommodating groove 110a, and a length of the overlapping portion in the axial direction of the sound emitting hole 110c may be other length values such as 0.1mm, 0.05mm, and the like, which is not specifically limited herein.

Specifically, the pressing portion 130a is an end of the pressing section 132 close to the sound outlet 110c.

Referring to fig. 2 and 4, when the pressing member 130 presses the sound outlet surface 123a of the microphone 120 against the sound outlet side 110b, the microphone 120 is not limited in the direction from the groove bottom to the notch of the accommodating groove 110a, and thus the stability of inserting the microphone 120 into the accommodating groove 110a cannot be ensured. In view of this, in order to ensure the stability of the microphone 120 inserted into the accommodating groove 110a, in an embodiment of the present invention, a side of the microphone 120 facing away from the sound outlet 110c is provided with a limiting concave portion 120a, and the pressing member 130 is provided with a limiting convex portion 130b for cooperating with the limiting concave portion 120a. With this arrangement, by means of the matching between the limit concave part 120a and the limit convex part 130b, the microphone 120 can be limited in the direction from the groove bottom to the notch of the accommodating groove 110a, and the stability of inserting the microphone 120 into the accommodating groove 110a is ensured.

Specifically, the limiting concave part 120a is disposed on a side of the mounting plate 121 opposite to the microphone body 122 and is configured as a limiting groove, so that the limiting concave part 120a is conveniently formed. In other embodiments, the limiting recess 120a may also be formed by a ring-shaped structural member surrounding the side of the mounting plate 121 opposite to the microphone body 122. The number of the limiting protrusions 130b is the same as that of the limiting recesses 120a, and each of the limiting recesses and the limiting protrusions may be one or more, which is not particularly limited herein.

Referring to fig. 2 and 4, in an embodiment of the present invention, an interval between two groove walls of the accommodating groove 110a in the axial direction of the sound outlet hole 110c is greater than an interval between two sides of the microphone 120 in the axial direction of the sound outlet hole 110c. With this arrangement, when the microphone 120 is inserted into the housing groove 110a, a gap can be formed between the sound emitting surface 123a and the sound emitting side 110b of the microphone 120, and the sound emitting surface 123a of the microphone 120 is effectively prevented from being deformed by interference of the groove wall of the housing groove 110a and becoming clogged with the sound. In addition, in combination with the setting of the pressing part 130a, the pressing part 130a can effectively compensate for a difference between a distance between two groove walls of the accommodating groove 110a in the axial direction of the sound outlet hole 110c and a distance between two sides of the microphone 120 in the axial direction of the sound outlet hole 110c, so as to ensure the elastic pressing strength of the pressing part 130 to the microphone 120.

The difference between the distance between the two groove walls of the accommodating groove 110a in the axial direction of the sound outlet hole 110c and the distance between the two sides of the microphone 120 in the axial direction of the sound outlet hole 110c may be other length values such as 0.1mm, 0.05mm, and the like, and is not particularly limited herein.

In other embodiments, the distance between the two groove walls of the receiving groove 110a in the axial direction of the sound outlet hole 110c may be equal to the distance between the two sides of the microphone 120 in the axial direction of the sound outlet hole 110c.
