[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this utility model, not all embodiments.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0032] Example 1:

[0033] Please see Figures 1 to 2 The microphone capsule fixing structure of this utility model is used for the headset of an earphone, including: a microphone shell 2; and a microphone capsule silicone base 1, which is disposed inside the microphone shell 2. The microphone capsule silicone base 1 is provided with a mounting hole 11 for mounting the microphone capsule 3, and both ends of the microphone capsule silicone base 1 are provided with buffer tension arms 12; wherein, the microphone shell 2 is provided with a positioning mechanism 23 that matches the buffer tension arms 12, and the buffer tension arms 12 are fixed on the positioning mechanism 23.

[0034] Specifically, the microphone capsule 3 is positioned within the mounting hole 11 of the microphone capsule silicone base 1. The microphone capsule silicone base 1 serves to fix, limit, and protect the microphone capsule 3, preventing external structures from directly pressing on it. Simultaneously, the silicone properties of the microphone capsule silicone base 1 also provide shock absorption. The microphone capsule 3 is fixed within the microphone housing 2 via the microphone capsule silicone base 1, ensuring that the microphone capsule 3 does not directly contact the microphone housing 2, thus preventing external vibrations from affecting the microphone's sound pickup quality. The buffer tension arm 12 is fixed to the positioning mechanism 23 of the microphone housing 2. The buffer tension arm 12 extends away from the microphone capsule 3. The microphone capsule silicone base 1 is fixed to the microphone housing 2 via the buffer tension arms 12 at both ends, ensuring that the mounting hole 11 of the microphone capsule silicone base 1 does not directly contact the microphone housing 2. The buffer tension arm 12 utilizes the soft properties of silicone to provide cushioning, effectively reducing vibrations transmitted to the microphone capsule 3 and minimizing the impact on its sound pickup performance.

[0035] Example 2:

[0036] This embodiment is a further structural optimization of the silicone base 1 for the microphone head of this utility model. Please refer to [link / reference]. Figure 3 and Figure 4 .

[0037] In some embodiments, the buffer tension arm 12 includes an extension 121 and a support column 122, the support column 122 being disposed on one end of the extension 121 away from the silicone base 1 of the microphone head; the positioning mechanism 23 includes a snap-fit ​​fixing hole 231 that matches the extension 121; wherein, the width of the support column 122 is greater than the width of the extension 121, and the support column 122 abuts against the outer side of the snap-fit ​​fixing hole 231.

[0038] Specifically, the buffer tension arm 12 is fixedly connected to the microphone shell 2 via the support column 122. The extension 121 on the buffer tension arm 12 increases the distance between the microphone head and the fixed position on the microphone shell 2. Both the buffer tension arm 12 and the microphone head silicone base 1 are made of silicone. The flexibility of silicone allows the extension 121 to reduce vibrations from the microphone shell 2, preventing wind noise from affecting the sound reception. The extension 121 of the buffer tension arm 12 can deform under force, thereby adjusting to match the length of the audio cable inside the microphone shell 2, preventing the audio cable from being overly tight or loose, which could cause poor sound reception.

[0039] During assembly, the extension 121 of the buffer tension arm 12 is adapted to the snap-fit ​​fixing hole 231 of the positioning mechanism 23, and the two cooperate to achieve snap-fit ​​fixing. The bracket column foot located at the end of the extension 121 is used to abut against the outer side wall of the snap-fit ​​fixing hole 231 to increase the static friction between the structures and prevent the buffer tension arm 12 from snapping off.

[0040] In some embodiments, the extension 121 is provided with a positioning notch 123, which is located near the bracket column foot 122 and is used to engage with the locking hole 231 for limiting.

[0041] Specifically, the buffer tension arms 12 at both ends of the silicone base 1 of the microphone head are provided with positioning notches 123. The positioning notches 123 are located at the connection between the extension 121 and the support column 122. The positioning mechanism 23 is provided with snap-fit ​​fixing holes 231 at the position opposite to the positioning notches 123.

[0042] Understandably, during the assembly process, the positioning notch 123 on the buffer tension arm 12 is inserted into the snap-fit ​​fixing hole 231 in the positioning mechanism 23. The positioning notch 123 is used to limit and fix the buffer tension arm 12, which can prevent the positioning mechanism 23 from sliding horizontally along the extension 121, thereby achieving the overall fixation of the silicone base 1 of the microphone head.

[0043] For ease of connection, in some embodiments, the support column 122 protrudes at the end in an arc shape.

[0044] Specifically, the support column 122 protrudes towards the end, and the support column 122 plays a stabilizing role. Its arc-shaped protrusion design can better realize plug-in installation and also plays a guiding role.

[0045] To increase the protection strength of the microphone head, in some embodiments, guide protection edges 111 are provided on both sides of the opening edge of the mounting hole 11, and the guide protection edges 111 are convex in the direction away from the mounting hole 11.

[0046] Specifically, guide guard edges 111 are added to the openings on both sides of the mounting hole 11. The guide guard edges 111 protrude away from the mounting hole 11, and the protruding part has a rounded corner structure. They serve as guides during the installation of the microphone head 3, facilitating assembly. The guide guard edges 111 increase the safety distance of the mounting hole 11, preventing external components from directly contacting the mounting hole 11 and thus squeezing the microphone head 3 and affecting the sound reception. The guide guard edges 111 also enhance the structural strength.

[0047] In some embodiments, the guide guard edge 111 is provided with a first wire groove 13, which connects to the mounting hole 11. The end of the buffer tension arm 12 is provided with a second wire groove 14, which extends toward the first wire groove 13. Specifically, the silicone base 1 of the microphone head is provided with a wire groove to facilitate the routing of the audio lead wire, preventing the audio lead wire from protruding and causing incomplete coverage of the tuning cotton 22 during installation, resulting in uneven sound pickup.

[0048] In this embodiment, the extension 121 of the buffer tension arm 12 can reduce vibrations from the microphone shell 2. The buffer tension arm 12 can also prevent the audio lead from being overly tight or loose, which could cause poor sound reception. The microphone silicone base 1 is connected by engaging the positioning notch 123 with the snap-fit ​​fixing hole 231. A wire groove is provided on the microphone silicone base 1 to facilitate the routing and installation of the audio lead of the microphone 3, and to prevent the tuning cotton 22 from squeezing the audio lead and creating gaps, thereby affecting the sound reception quality of the microphone 3.

[0049] Example 3:

[0050] This embodiment further optimizes the structure of the mithril 2 based on the above embodiments. Please refer to [link to relevant documentation]. Figure 5 and Figure 6 .

[0051] In some embodiments, the microphone capsule fixing structure further includes tuning cotton 22 and a vent 21. The vent 21 is opened on one side of the microphone shell 2, and one side of the tuning cotton 22 covers the inside of the vent 21, while the other side abuts against the opening of the mounting hole 11.

[0052] Specifically, the microphone shell 2 has a vent 21 on the side near the microphone head 3 used for sound reception, and a tuning cotton 22 is placed inside the vent 21. One side of the tuning cotton 22 covers the vent 21, and the other side of the tuning cotton 22 abuts against the opening of the mounting hole 11, thus covering the microphone head 3 inside the mounting hole 11 and preventing the microphone head 3 from jumping out of the mounting hole 11 or tilting or flipping. The positioning mechanism 23 also abuts against the tuning cotton 22, effectively preventing the tuning cotton 22 from tilting during assembly. The positioning mechanism 23 can prevent the tuning cotton 22 from squeezing the microphone head 3 during installation, enhancing the effective airflow of sound. The setting of the tuning cotton 22 can effectively reduce the impact of wind noise from the external environment.

[0053] In some embodiments, ventilation holes 21 are provided on both opposite sides of the microphone shell 2, and an open cavity is formed between the ventilation holes 21 on both sides of the microphone shell 2.

[0054] Specifically, the mounting hole 11 is a through hole, and the microphone head 3 is embedded in the mounting hole 11, so that the microphone head 3 can pick up sound in both opposite directions. The microphone shell 2 adopts a split design, consisting of a microphone shell upper cover 24 and a microphone shell lower cover 25 that are inserted and fitted together. Both the microphone shell upper cover 24 and the microphone shell lower cover 25 are provided with vent holes 21, which are positioned opposite to the microphone head 3, increasing the pickup range of the microphone head 3. Understandably, in order to avoid the tuning cotton 22 not being placed properly during production and assembly, the protrusion 27 of the microphone shell upper cover 24 and the column 26 of the microphone shell lower cover 25 can be inserted and fitted together to achieve pre-fixation of the microphone shell 2 assembly. The edges of the microphone shell upper cover 24 and the microphone shell lower cover 25 are spliced ​​together and then connected by ultrasonic fastening. Compared with traditional screw fastening and glue bonding methods, this improves production efficiency, and the ultrasonic fastening has better sealing performance, which can prevent external sound from entering the microphone shell 2 from the connection point, thereby affecting the sound reception effect.

[0055] In some embodiments, a tuning mesh 4 and a microphone shell steel mesh 5 are sequentially provided on the outer side of the vent 21.

[0056] Specifically, the microphone shell 2 has a tuning mesh 4 on the outside of the vent 21. The tuning mesh 4 can adjust the microphone's pickup angle and sensitivity distribution, reduce the sound intensity difference caused by different pickup directions, and ensure that the sound from multiple directions can be picked up relatively consistently, making the transmitted sound more natural and realistic.

[0057] In addition, a microphone shell steel mesh 5 is provided outside the tuning mesh 4. The microphone shell steel mesh 5 can work together with the tuning mesh 4 to further optimize the acoustic performance of the microphone. It can also act as an isolation barrier to prevent the external environment from impacting and bumping the headset, increasing the strength of the overall structure. The microphone shell steel mesh 5 can also prevent the incoming wind from blowing directly onto the ventilation hole 21, reducing the generation of wind noise.

[0058] For better sound reception and structural strength, in some embodiments, both the microphone shell steel mesh 5 and the tuning mesh 4 protrude outward in an arc shape.

[0059] Specifically, the microphone shell steel mesh 5 covers the outside of the tuning mesh 4. Both of them bulge outward in an arc shape. The raised structure can increase the structural strength of the microphone shell steel mesh 5, and also make the open cavity formed by the tuning mesh 4 larger, with better sound flow, which can reduce the impact of sound reflection and resonance on sound reception.

[0060] In this embodiment, the tuning mesh 4 is first pre-fixed to the microphone shell 2 using a snap-fit ​​structure, and then together with the microphone shell steel mesh 5, it is fixed to the microphone shell 2 with glue, increasing the stability of the overall structure. Both the microphone shell steel mesh 5 and the tuning mesh 4 protrude outward in an arc shape. The raised structure not only increases the overall strength but also makes the sound flow within the open cavity space better. Moreover, the microphone shell steel mesh 5 and the tuning mesh 4 can filter and reduce wind, effectively reducing the impact of wind noise on the headset. The vent holes 21 of the mesh structure can increase the sound entry area, making the sound pickup more natural and clear. The mounting hole 11 in the silicone base 1 of the microphone capsule adopts a through structure, and the bidirectional opening allows the microphone capsule 3 to have a larger sound pickup range. Furthermore, the microphone shell 2 adopts a split design, which facilitates the assembly of the tuning cotton 22. The tuning mesh 4 and the microphone shell 2 form an open cavity, preventing external wind from blowing directly onto the vent 21, which can effectively reduce wind noise. The tuning mesh 4 can adjust the microphone's pickup angle. The microphone shell steel mesh 5 can work with the tuning mesh 4 to optimize the sound pickup performance. The microphone shell steel mesh 5 is also used to prevent external impacts and bumps.
