Detailed implementation manners

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. The described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0035] Therefore, the detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the claimed present utility model, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0036] Embodiment 1:

[0037] Please refer to the attached Figure 1-3, the sound receiving mechanism of the present utility model includes a sound head 1, a directional component 2, and an auxiliary component 3; the directional component 2 includes a headgear 21 and a directional member 22, and the directional member 22 is arranged in an annular array along the outer edge of the headgear 21; a receiving cavity 211 adapted to the sound head 1 is provided inside the headgear 21, and the sound head 1 is embedded in the receiving cavity 211; the auxiliary component 3 is connected to the directional member 22. Preferably, there are 4 directional members 22, which can effectively balance the forces acting on the four directions of the headgear 21.

[0038] In the sound receiving mechanism 100 of this embodiment, the sound head 1 is placed in the receiving cavity 211, so that the headgear 21 positions and restricts the sound head 1. Then, the directional members 22 are arranged in an annular array along the outer edge of the headgear 21, so that the directional members 22 can balance the forces acting on the headgear 21 in all directions, ensure the stability of the placement of the headgear 21, and further avoid the phenomenon of the sound head 1 being skewed, ensure the stability of the placement of the sound head 1 and good sound reception performance, avoid the phenomenon of howling and irritating the hearing, and further improve the user's comfort and facilitate the continuous use of the operator.

[0039] In addition, the connection between the directional member 22 and the auxiliary component 3 is a fixed connection. Through the setting of connecting the directional member 22 and the auxiliary component 3, the directional member 22 and the auxiliary component 3 move synchronously, thereby ensuring the stability of the connection of the directional member 22, ensuring the relative static state of the positions between the sound head 1, the directional component 2, and the auxiliary component 3, and improving the stability of the sound head 1.

[0040] In the sound receiving mechanism 100 with this structure, the overall structure design is simple. The positioning component is used to avoid the phenomenon of the sound head 1 being skewed, and accordingly, the phenomenon of howling can be avoided, ensuring the normal operation of the sound receiving mechanism 100 and guaranteeing the quality of the sound receiving mechanism 100. And because the improved structure is simple, it is convenient to manufacture, has strong practicability, effectively ensures the durability of the sound receiving mechanism 100, and correspondingly improves the customer's satisfaction.

[0041] Embodiment 2:

[0042] The difference between this embodiment and Embodiment 1 is as follows. Please refer to Figure 4 , the auxiliary component 3 of this embodiment includes a support portion, and the support portion includes a plurality of brackets 311 arranged in an annular array; the brackets 311 are connected to the directional members 22. Preferably, there are 4 brackets 311. By fixedly connecting each directional member 22 to the corresponding bracket 311, the connection independence of the plurality of directional members 22 is ensured, the stability of the directional members 22 is ensured, and further the stability of the headgear 21 is ensured.

[0043] In some embodiments, the head cover 21 is an elastic head cover 21. Preferably, the elastic head cover 21 can be made of silicone material, so that the head 1 can be inserted into the head cover 21 by stretching the head cover 21, which not only improves the convenience of inserting the head cover 1 into the head cover 21, but also provides a certain degree of protection for the fixation of the head cover 21 due to the flexibility of the silicone material, avoiding wear caused by hard contact.

[0044] For details, see Figure 5 The head cover 21 includes a cover body 214, a first limiting ring 212 and a second limiting ring 213. The first limiting ring 212 is connected to one end of the cover body 214, and the second limiting ring 213 is connected to the other end of the cover body 214. The cover body 214, the first limiting ring 212 and the second limiting ring 213 are arranged to form a receiving cavity 211. The first limiting ring 212 and the second limiting ring 213 can limit the two ends of the sound head 1, thereby ensuring the stability of the sound head 1 embedded in the receiving cavity 211 and ensuring the normal operation of the sound head 1.

[0045] It can be understood that the assembly process of the sound head 1 is as follows: first, the welded sound head 1 is inserted into the accommodating cavity 211, and then the sound head 1 is welded to the main PCBA. The assembly is simple and the sound head 1 has good stability.

[0046] In some embodiments, the directional member 22 is an elastic directional member 22. Preferably, the elastic directional member 22 can be made of silicone material. In this way, by utilizing the softness of silicone, the directional member 22 can reduce the vibration of the sound head 1, avoid excessive tension or relaxation of the lead wire of the sound head 1, provide a good directional effect for the sound head 1, further avoid the howling phenomenon, and ensure the continuous use of the sound head 1.

[0047] For details, see Figure 5 The directional member 22 includes a traction foot 221 and a connecting block 222, wherein the traction foot 221 is fixedly connected to the connecting block 222; the traction foot 221 is connected to the outer edge of the head cover 21, and the connecting block 222 is connected to the auxiliary component 3. In this way, the directional member 22 is similar to a spider web, and the traction foot 221 can effectively buffer the force of the head cover 21, thereby reducing the vibration of the sound head 1 and ensuring the connection stability of the lead wire of the sound head 1. The stability of the head cover 21 and the traction foot 221 is ensured by the connecting block 222, thereby ensuring the continuous normal use of the sound head 1. The directional member 22 has a simple structure, is easy to manufacture, and has strong practicality.

[0048] In some embodiments, a connection hole 2221 is provided in the middle of the connection block 222. Figure 6, the bracket 311 includes a frame body 3111 and a connecting column 3112, and the connecting column 3112 is connected to the upper end of the frame body 3111; the connecting column 3112 passes through and is connected to the connecting hole 2221. In this way, the connecting block 222 and the bracket 311 are connected and fixed, and the assembly is convenient. Pull the connecting block 222 to the upper end of the connecting column 3112, align the connecting hole 2221 with the connecting column 3112, and make the connecting hole 2221 sleeved on the connecting column 3112, so as to realize the connection between the two. The assembly operation is easy and convenient, and it is convenient for subsequent maintenance operations. In order to further strengthen the stability of the connecting block 222 and the connecting column 3112, UV glue can be applied between the connecting column 3112 and the connecting hole 2221 for fixation.

[0049] In some embodiments, please refer to Figure 7 , the auxiliary component 3 further includes a housing 32, and the housing 32 is sleeved on the sound head 1, the directional component 2 and the support part. A windproof cotton 321 is arranged between the inner wall of the housing 32 and the support part. Through the arrangement of the housing 32, a certain protection effect can be provided for the internal structure of the sound receiving mechanism 100, thereby improving the rigidity of the sound receiving mechanism 100, effectively avoiding the internal components from being affected by external factors, and increasing the durability of the sound receiving mechanism 100. And by arranging the windproof cotton 321, the influence of the external wind speed on the sound head 1 can be avoided, and the sound quality of the sound received by the sound head 1 can be guaranteed.

[0050] In addition, through the arrangement of the bracket 311, the phenomenon that the windproof cotton 321 is skewed and squeezes the sound head 1 can be effectively avoided, thereby avoiding hindering the effective flow of air and improving the sound quality of sound reception.
