[0043] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0044] like Figures 1 to 3As shown, this embodiment provides a microphone fixing mechanism, which includes a housing 100, a circuit board 200, a sealing member 400 and a fixing member 500, wherein the housing 100 is provided with a limiting groove 110; the circuit board 200 is at least partially inserted in the limiting groove 110; the microphone 300 is arranged on the circuit board 200; at least part of the sealing member 400 is located on the side of the microphone 300 away from the circuit board 200; the fixing member 500 is located on the side of the circuit board 200 away from the microphone 300; the part of the circuit board 200, the microphone 300, the sealing member 400 and the fixing member 500 located in the limiting groove 110 form an assembly member 600; at least in the front-to-back direction, the assembly member 600 is interference-fitted in the limiting groove 110; at least one of the sealing member 400 and the fixing member 500 is made of silicone or rubber. In this embodiment, the sealing member 400 and the fixing member 500 are both made of silicone.

[0045] With the aid of the above-mentioned assembly relationship, the assembly part 600 can be detachably installed in the limiting groove 110. In the front-to-back direction, one of the sealing part 400 and the fixing part 500 can undergo elastic deformation, so that under the action of external force, the size of the assembly part 600 in the front-to-back direction can be changed. When the size of the assembly part 600 in the front-to-back direction is smaller than the size of the limiting groove 110 in the front-to-back direction, the assembly part 600 can be easily removed from the limiting groove 110, and the microphone 300 can be repaired separately, thereby avoiding the microphone 300 being scrapped and replaced together with the shell 100 after being damaged, thereby reducing the maintenance cost.

[0046] The seal 400 has a sealing groove, the opening of which faces the circuit board 200, and the seal 400 is sleeved on the outside of the microphone 300. Exemplarily, the seal 400 includes an end sealing portion and a peripheral sealing portion provided on the end sealing portion, the end sealing portion is provided at one end of the microphone 300 away from the circuit board 200, and the peripheral sealing portion is provided around the circumference of the microphone 300. The above arrangement can fully protect the end and circumference of the microphone 300, thereby ensuring the waterproof and moisture-proof performance of the microphone 300.

[0047] The diaphragm of the microphone 300 is located at one end of the microphone 300 away from the circuit board 200. To adapt to this structure, in this embodiment, the sealing member 400 is provided with a sound receiving hole 410 connected to the sealing groove. The sound receiving hole 410 is directly opposite to the diaphragm of the microphone 300. The side wall of the limiting groove 110 has an avoidance portion 130 at the sound receiving hole 410, and the sound receiving hole 410 is connected to the outside through the avoidance portion 130. The above arrangement enables the sound receiving hole 410 to enter the sound receiving hole 410 through the avoidance portion 130, and finally trigger the diaphragm of the microphone 300. It should be noted that the microphone 300 in this embodiment is an omnidirectional microphone 300.

[0048] In order to improve the convenience of assembling the microphone 300, in some embodiments, a guide surface 510 is provided at one end of the fixing member 500, and the guide surface 510 is inclined forward from top to bottom. This arrangement allows the fixing member 500 to be installed in the last step, that is, the microphone 300 with the seal 400 and the circuit board 200 are first placed in the limiting groove 110, and then the fixing member 500 is inserted into the gap between the circuit board 200 and the limiting groove 110, so that the circuit board 200, the microphone 300 and the seal 400 are pressed forward, so that the assembly member 600 is interference-fitted in the limiting groove 110; at the same time, due to the existence of the guide surface 510, when the fixing member 500 is inserted, the portion with a smaller thickness having the guide surface 510 enters the limiting groove 110 first, and in the process of the fixing member 500 continuing to enter the limiting groove 110, the thickness gradually increases, which makes the insertion of the fixing member 500 more convenient.

[0049] The circuit board 200 is a flexible circuit board 200. The flexible circuit board 200 is relatively soft and easily deformed. It may also be damaged under the extrusion. Therefore, in this embodiment, the microphone fixing mechanism also includes a support member 700. The support member 700 is arranged between the circuit board 200 and the fixing member 500, and at least part of it is located in the limiting groove 110. The support member 700 is plate-shaped and made of a material with strong supporting strength such as plastic or metal. The support member 700 has a high hardness and will not be deformed under the extrusion of the fixing member 500 and the sealing member 400, which is conducive to ensuring the shape of the circuit board 200 and reducing the probability of damage.

[0050] Along the extension direction of the support member 700, two opposite side walls of the limiting groove 110 are each provided with an avoidance groove 120, and the avoidance grooves 120 are both connected to the limiting groove 110, and the two ends of the support member 700 are respectively located in the corresponding avoidance grooves 120. In this embodiment, the extension direction of the support member 700 is the left-right direction, and the direction is perpendicular to the front-to-back direction of the connection line of the sealing member 400 and the fixing member 500. With the arrangement of the above structure, the two ends of the support member 700 are limited so that deflection does not occur, thereby improving the position stability of the circuit board 200 and the microphone 300 arranged on the circuit board 200; at the same time, the arrangement of the avoidance groove 120 also provides a position guide for the installation of the assembly part 600, effectively improving the assembly efficiency.

[0051] The shell 100 includes a shell bottom 1101 and a limiting edge 1102 protruding upward from the shell bottom 1101. The shell bottom 1101 also has a limiting protrusion 1103 protruding upward. The limiting protrusion 1103 and the limiting edge 1102 form a limiting groove 110. The shell 100 and the cover body cooperate to form the outer shell of the product. The cover body is provided with an annular groove. The limiting edge 1102 is annular and can be inserted into the annular groove. The above arrangement enables the formation of the limiting groove 110 with the help of the limiting edge 1102 structure, reducing the manufacturing difficulty and cost.

[0052] At least the portion of the limiting edge 1102 surrounding the limiting groove 110 is arc-shaped and protrudes forward. The side of the sealing member 400 away from the circuit board 200 is a planar structure, and a gap is formed between the planar structure and the arc-shaped limiting edge 1102, and the gap forms the avoidance portion 130, and there is no need to separately set the avoidance portion 130, thereby further reducing the manufacturing difficulty and cost of the limiting groove 110.

[0053] To facilitate the removal of the fixing member 500, in some embodiments, a notch 140 is provided at the position where the limiting protrusion 1103 abuts against the fixing member 500. The operator can insert a tool such as a screwdriver into the limiting groove 110 through the notch 140 and abut against the fixing member 500. Since the fixing member 500 is made of silicone, the tool can be partially sunk into the fixing member 500 and then moved away from the shell bottom 1101 to facilitate the fixing member 500 to be pulled upward from the limiting groove 110. The tool may or may not pierce the fixing member 500.

[0054] In the left-right direction, of the fixing member 500 and the sealing member 400, at least the width W1 of the fixing member 500 is smaller than the width W2 of the limiting groove 110. This arrangement ensures that the fixing member 500 will not be restricted on both sides during the process of being installed into the limiting groove 110, thereby facilitating the installation into the limiting groove 110 and improving the assembly efficiency of the fixing member 500.

[0055] In this embodiment, the circuit board 200 includes a main board 210 and split boards 220 disposed at both ends of the main board 210, at least part of the main board 210 is perpendicular to the split boards 220, and at least part of the split boards 220 is inserted into the limiting groove 110. Two microphones 300 are provided, and the two microphones 300 are disposed on the two split boards 220. Two fixing members 500 are respectively disposed corresponding to the two split boards 220. This arrangement enables two microphones 300 to be installed on one circuit board 200, which is conducive to improving the sound reception effect, and even if one microphone 300 is damaged, it does not affect normal use.

[0056] Regarding the relative position relationship in various directions, in this embodiment, the limiting groove 110 extends in the up-down direction, and the up-down direction, the left-right direction, and the front-back direction are perpendicular to each other.

[0057] This embodiment also provides a camera device, including the microphone fixing mechanism in the above embodiment. With the arrangement of the microphone fixing mechanism, the assembly 600 can be easily disassembled from the housing 100, thereby reducing the subsequent maintenance cost.

[0058] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
