In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] The utility model provides a microphone assembly for a head-mounted device, which can be a helmet-type device or a headphone-type device. The microphone assembly in the utility model includes a microphone rod 3, a microphone head, a connector 2 and a mounting seat 1, wherein the main function of the microphone head is to convert the sound signal into an electrical signal, the microphone head is located inside the microphone rod 3, and a through hole is provided on the microphone rod 3 for the sound to reach the microphone head. The electrical signal of the microphone head can be transmitted to an external device by wire or wirelessly. The specific structure of the microphone head is not described in detail in this article, please refer to the current technology.

[0040] In the utility model, the microphone rod 3 has a first end and a second end along its length direction, and the first end is provided with a microphone head. As mentioned above, the microphone head is located inside the microphone rod 3. A through hole is provided on the microphone rod 3. In order to prevent dust and other impurities from entering the microphone rod 3 and affecting the operation of the microphone head, a sponge cover 7 can be sleeved on the first end, and the sponge cover 7 can be further tied and connected with the microphone rod 3 by elastic ropes and other components.

[0041] The second end of the microphone rod 3 has a connector 2, and the microphone rod 3 is rotatably connected to the mounting seat 1 through the connector 2. The microphone rod 3 and the connector 2 can be an integrated structure, and of course the microphone rod 3 and the connector 2 can be a split structure, and the whole formed by the two can rotate relative to the mounting seat 1. The utility model shows a specific embodiment in which the microphone rod 3 and the connector 2 are split structures. The rotation axis of the connector 2 and the mounting seat 1 has an angle with the length direction of the microphone rod 3, and usually, the angle between the two is approximately 90°.

[0042] The mounting seat 1 in the utility model has a matching surface 1a on the side away from the microphone rod 3, and the matching surface 1a is adapted to the shell of the head-mounted device. The shape of the matching surface 1a depends on the corresponding position of the shell. For example, when the matching position on the shell is a curved surface, the matching surface 1a is a curved surface that matches the curved surface at the corresponding position of the shell; when the matching position on the shell is a plane, the matching surface 1a is a plane. The mounting seat 1 also has a mounting structure fixedly connected to the shell of the head-mounted device. In the case where the microphone is connected to an external device by wire, the cable 9 connecting the microphone passes through the microphone rod 3, the connector 2 and the mounting seat 1, and then enters the shell 200 from the threading hole of the shell 200, so that the cable 9 can be prevented from being exposed outside the microphone assembly. Among them, the through hole inside the connector 2 can be roughly L-shaped, and a slope 21a can be set at the junction of the L-shaped structure so that the cable can turn smoothly and facilitate the assembly of the cable.

[0043] The connecting body 2 and the mounting seat 1 can both be made of relatively light materials, such as plastic materials.

[0044] The microphone assembly of the utility model is provided with a mounting seat 1, and a microphone rod 3 is rotatably mounted on the mounting seat 1 through a connector 2. The mounting seat 1 has a mating surface 1a that matches the housing of the head-mounted device, and the mating surface 1a and the housing can be fitted and installed to minimize the gap between the two. The mounting seat 1 can be directly fixed to the housing through a mounting structure provided thereon, so that the rotation of the microphone rod 3 in the microphone assembly does not need to rely on the housing 200, and the components in the microphone assembly can be assembled in advance, thereby improving the efficiency of assembling the head-mounted device, and the housing only needs to be provided with a structure that matches the mounting structure, and the housing structure is simple.

[0045] In the present invention, the mounting structure can be an internal threaded hole, which can be directly processed on the mating surface 1a of the mounting seat 1. Of course, the internal threaded hole is formed by pre-embedded screw sleeves and other components inside the mounting seat 1. A through hole can be set on one side of the shell, and the threaded portion of the screw component 8 can pass through the shell from one side of the shell 200 and connect to the internal threaded hole, so that the connection and fixation of the microphone assembly and the shell are realized. In this fixing method, the screw component and other connecting parts will not be exposed to the outside, thereby improving the appearance of the device.

[0046] In a specific embodiment, the connecting body 2 has a rotating shaft 23 protruding toward the mounting seat 1, and the mounting seat 1 is provided with a first through hole. At least part of the shaft section of the rotating shaft 23 is located inside the first through hole and rotates with the peripheral wall of the first through hole; in addition to rotating with the rotating shaft 23, the first through hole can also serve as a passage for the connection microphone harness to pass through. The microphone assembly also includes a limiter for limiting the rotating shaft 23 from escaping from the first through hole.

[0047] In this embodiment, the manner in which the connecting body 2 is rotatably connected to the mounting seat 1 is relatively simple.

[0048] In a specific embodiment, the limiting member includes a retaining spring 6, which is disposed on the end of the rotating shaft 23 extending out of the first through hole. Specifically, an annular groove may be disposed on the rotating shaft 23, and the retaining spring 6 is fixed to the annular groove. The retaining spring 6 may be a standard part, and no additional design or processing is required. The inner diameter and outer diameter of the retaining spring 6 may be reasonably set according to the application structure, as long as it can avoid slipping out of the first through hole. The retaining spring 6 has a simple shape, light weight, reliable limiting, and is easy to install.

[0049] The clamping ring 6 may be provided with a clamping hole for the clamping ring 6 , that is, the clamping ring 6 is a clamping ring with an opening, which further facilitates the installation and removal of the clamping ring 6 .

[0050] In a specific embodiment, a groove 14 is further provided on the side of the mounting base 1 away from the microphone rod 3, the groove 14 is coaxial with the first through hole, and the clamp spring 6 is located inside the groove 14. In this embodiment, the outer diameter of the clamp spring 6 is larger than the diameter of the first through hole and smaller than the diameter of the groove 14. After the clamp spring 6 is installed, it is located inside the groove 14, which not only further reduces the space occupied by the component, but also allows the clamp spring 6 to be installed and removed from one side of the groove 14.

[0051] Of course, the installation method of the clamping spring 6 is not limited to the description herein, and the clamping spring 6 can also be installed inside the first through hole. In addition to the clamping spring 6, the limiting member can also be a pin or a pin shaft.

[0052] In a specific embodiment, the microphone assembly further includes a damping component, which is installed between the connector 2 and the mounting base 1, and is used to provide rotational damping between the connector 2 and the mounting base 1. The damping component provides rotational damping, so that when the connector 2 rotates relative to the mounting base 1, under the action of the rotational damping, the connector 2 can be rotated and stopped at any position, thereby adjusting the position of the microphone rod 3, so that the microphone head is facing the user's mouth, and improving the flexibility of the use of the microphone assembly.

[0053] In a specific embodiment, the damping component includes at least one elastic damping ring 4, each elastic damping ring 4 is sleeved on the rotating shaft 23 and is tensioned between the rotating shaft 23 and the first through hole. The inner ring of the elastic damping ring 4 is interference fit with the rotating shaft 23, and the outer ring is interference fit with the first through hole. The microphone rod 3 is rotated and stopped at any position through the interference fit between the parts, and the rotation is reliable and stable, the structure is simple, and the weight is relatively light.

[0054] The elastic damping ring 4 may be an annular column, so that the contact area between the rotating shaft 23 and the first through hole is relatively large, and a large rotation damping can be formed. The material of the elastic damping ring 4 may be a wear-resistant material PE, and the wear-resistant material can increase the service life of the elastic damping ring 4. The number of the elastic damping ring 4 may be one, or two or more, depending on the rotation damping required by the component.

[0055] In a specific embodiment, the rotating shaft 23 includes a first shaft section 231 and a second shaft section 232 connected to each other, the diameter of the second shaft section 232 is smaller than that of the first shaft section 231, the first through hole includes a large diameter hole section 12 and a small diameter hole section 13, and the elastic damping ring 4 is installed between the first shaft section 231 and the large diameter hole section 12 by interference fit. In this embodiment, the size of the large diameter hole section 12 is relatively large, which is conducive to installing the elastic damping ring 4 with a larger size and improving the strength of the elastic damping ring 4 to a certain extent. In addition, the size of the small diameter hole section 13 is relatively small, which can also improve the use strength of the mounting seat 1 to a certain extent.

[0056] In this embodiment, the limiting components such as the retaining spring 6 are connected to the second shaft segment 232 .

[0057] The connector 2 has a second through hole 21 inside, and the second end of the microphone rod 3 includes a first section 31 with a polygonal cross section. The first section 31 can be a rectangular cylinder, that is, the cross section of the first section 31 is rectangular. Of course, the first section 31 can also be a triangular cylinder, and the cross section of the first section 31 is triangular. Of course, the cross section of the first section 31 can also be a pentagon or a hexagon or other polygons. Correspondingly, the second through hole 21 includes a polygonal hole section 212 that is inserted and matched with the first section, so that when the first section is inserted and matched with the polygonal hole section 212, the microphone rod 3 and the connector 2 cannot rotate relative to each other in the circumferential direction, which is convenient for the microphone rod 3 to be quickly positioned and accurately installed in the circumferential direction.

[0058] In addition, the microphone assembly further comprises a locking member, which locks the axial position of the connecting body 2 and the microphone rod 3. Under the action of the locking member, the first section 31 cannot escape from the polygonal hole section 212, and the microphone rod 3 is prevented from loosening and falling off.

[0059] Of course, the microphone rod 3 also includes a second section 32 connected to the first section 31, the second section 32 is connected to the side of the first section 31 close to the microphone head, the second section 32 can be a cylindrical section, the diameter of the second section 32 is larger than the first section 31, the second through hole 21 also includes a positioning hole section 211 located outside the polygonal hole section 212 and connected thereto, when assembled, the second section is at least partially located inside the positioning hole section 211, and the annular end 321 of the second section 32 facing the first section 31 abuts against the bottom wall 2111 of the positioning hole section 211. Of course, the second section 32 and the positioning hole section 211 can be interference fit. In this embodiment, the bottom wall 2111 of the positioning hole section 211 can play a role in axial positioning of the microphone rod 3 inserted into the second through hole 21 of the connector 2, which is convenient for quick assembly.

[0060] In a specific embodiment, the locking component can be a pin 5, the hole wall of the polygonal hole section 212 is provided with a third through hole, the peripheral wall of the first section 31 is provided with a notch 311, and the pin 5 is inserted into the third through hole and the notch 311. In this embodiment, the pin 5 can be completely located inside the connector 2, improving the appearance of the microphone assembly.

[0061] In the utility model, the third through hole includes a first hole section 22 and a second hole section connected to each other. The first hole section 22 is a receiving groove that penetrates the first shaft section 231 and forms an outwardly opening groove on the peripheral wall of the first shaft section 231. The receiving groove can be an arc groove, which is easy to process. The pin includes a first segment 54 and a second segment 51 connected to each other. The first segment 54 is opposite to the first shaft section 231, and the first segment 54 cooperates with the receiving groove. The first segment 54 of the pin is as completely located as possible inside the receiving groove or after the first segment 54 is installed in the receiving groove, it forms a complete outer surface with the first shaft section 231, as long as it does not affect the installation of the elastic damping ring 4.

[0062] The second hole segment extends from the first shaft segment 231 to the polygonal hole segment 212, and the end of the second segment 51 is inserted into the microphone rod 3. The cross-section of the second hole segment is a non-circular structure. For example, the second hole segment can be a waist-shaped hole. The second segment 51 cooperates with the second hole segment, so that the second segment 51 and the second hole segment cannot rotate relative to each other in the circumferential direction, and then the pin shaft cannot rotate inside the third through hole, thereby improving the axial locking effect of the pin shaft on the microphone rod 3.

[0063] In a specific embodiment, the surface of the first section 54 of the pin facing away from the receiving groove further has a take-out hole 52. When the pin needs to be taken out, the wave member can be inserted into the take-out hole 52 to take the pin out in the axial direction.

[0064] The first segment 54 may further include a convex buckle 53 for engaging with a concave buckle inside the receiving groove to limit the pin from axially escaping from the third through hole.

[0065] In a specific embodiment, one of the two opposite end surfaces of the mounting seat 1 and the connecting body 2 is provided with a protrusion 11, and the other is provided with an arc-shaped groove 24. When the connecting body 2 rotates relative to the mounting seat 1, the protrusion 11 slides within the range of the arc-shaped groove 24. By setting the length of the arc-shaped groove 24, the rotation range of the connecting body 2 can be limited. This article shows that the angle of the arc-shaped groove 24 is 160 degrees.

[0066] Under the premise of not affecting the use strength of the connector 2, a weight-reducing groove 25 may be further provided on the end surface of the connector 2.

[0067] The utility model also provides an assembly process of a head mounted device, which is as follows:

[0068] First, adjust the directions of the microphone rod 3 and the connector 2 to ensure that the notch 311 of the microphone rod 3 is in the same direction as the rotating shaft 23 of the connector 2, and then insert the first section 31 of the microphone rod 3 into the polygonal hole section 212 of the connector 2 until the annular end face 321 of the microphone rod 3 fits with the bottom wall 2111 of the positioning hole section 211 of the connector 2, and then insert the second section 51 of the pin 5 into the first hole section 22 of the connector 2 until the convex buckle 52 of the pin 5 fits with the concave buckle of the connector 2. At this time, the second section 51 of the pin 5 has been inserted into the notch 311 of the microphone rod 3 to lock the microphone rod 3 in the connector 2. In this process, a small amount of yellow glue is applied to the first hole section 22 and the second through hole 21 of the connector 2 to reinforce the connection between the connector 2 and the microphone rod 3 and the pin 5 to form a connector assembly.

[0069] Insert the two elastic damping rings 4 into the large diameter hole section 12 of the mounting seat 1, then adjust the direction of the connector assembly and the mounting seat 1, ensure that the arc groove 24 of the connector 2 is opposite to the protrusion 11 of the mounting seat 1, and then buckle the connector assembly into the small diameter hole section 13 of the mounting seat 1 until the large end face of the cone of the connector 2 fits with the end face of the mounting seat 1, use the circlip pliers to pull the circlip 6 open, and then insert the circlip 6 from the end face of the rotating shaft body 23 of the connector 2 into the groove of the rotating shaft body 23, take out the circlip pliers, and complete the assembly of the microphone assembly; place the microphone assembly at the corresponding mounting hole position outside the helmet shell 200, adjust the position, align the hole position, ensure the position of the microphone rod 3 on the helmet shell 200, ensure that the outer curved surface of the helmet fits with the matching surface of the microphone assembly, and then install the screw assembly (screw component) inside the helmet, and the screw assembly locks the embedded nut 15 of the mounting seat 1.

[0070] When in use, put the helmet equipped with the microphone assembly on the head, turn the microphone rod 3 by hand to make the microphone rod 3 rotate relative to the mounting seat 1 until the microphone head of the microphone rod 3 rotates to the vicinity of the mouth, then gently bend the gooseneck tube by hand until the positions of the microphone rod 3 and the mouth are suitable for talking; when taking off the helmet, turn the microphone rod 3 by hand to make the microphone rod 3 rotate along the mounting seat 1 until the microphone rod 3 rotates to the maximum rotation position on the top of the helmet, and then take off the helmet.
