Description

Technical Field

[0001] This utility model relates to the field of microphone technology, specifically a bone conduction silicon microphone. Background Technology

[0002] The sound of your own voice when you speak is completely different from the sound of a recording of yourself speaking on your phone and then played back on the phone. The sound has changed. This difference is mainly caused by the lack of bone conduction (including cavity) information. In other words, the process of a person speaking and listening to themselves involves two stages: air conduction sound pickup and bone conduction sound pickup.

[0003] Bone conduction, as discussed here, uses the skull as a sound transmission medium. Bone conduction technology is divided into bone conduction loudspeaker technology and bone conduction microphone technology. Bone conduction loudspeaker technology converts alternating audio electrical signals into mechanical vibrations, which are then transmitted through the skull to the auditory nerve to produce the sensation of hearing.

[0004] However, traditional bone conduction silicon microphones can only be placed close to the human head to meet the needs of sound conduction, which results in a single application mode. But users' working environments are not static, which means that the microphone cannot adapt to diverse working environments. Utility Model Content

[0005] The purpose of this invention is to provide a bone conduction silicon microphone to solve the problems mentioned in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bone conduction silicon microphone, comprising a bone conduction microphone, a ventilation slot on one side of the bone conduction microphone, a U-shaped frame one and a U-shaped frame two fixedly connected to one side of the bone conduction microphone, a connecting frame and two plug-in plates provided between the U-shaped frame one and the U-shaped frame two, a mounting plate one provided inside the U-shaped frame one, a bolt rotatably connected to the mounting plate one, a nut threaded on the outer side of the bolt, a plurality of pin rods fixedly connected to one side of the mounting plate one, and a sealing component provided between the mounting plate one and the bone conduction microphone.

[0007] Preferably, the two plug-in plates are fixedly connected to the top and bottom of the connecting frame, respectively, and the connecting frame has multiple plug holes on one side.

[0008] Preferably, the second U-shaped frame has multiple insertion holes on one side, and the first U-shaped frame has two storage slots on one side. The bolts and nuts are both located inside one of the storage slots, and the nuts are fixedly connected to the first U-shaped frame.

[0009] Preferably, one of the needle bars is disposed inside another storage slot, one end of the needle bar is fixedly connected to a supporting short shaft, and the other multiple needle bars are disposed inside a U-shaped frame.

[0010] Preferably, a circular groove is provided on one side of the U-shaped frame, and an internal hexagonal fitting is fixedly connected to the end of the bolt away from the second U-shaped frame, with the internal hexagonal fitting located on one side of the circular groove.

[0011] Preferably, the U-shaped frame has a U-shaped guide groove inside, and the mounting plate is inserted into the U-shaped guide groove.

[0012] Preferably, the sealed component includes a barrier plate disposed inside the ventilation slot and fixedly connected to the bone conduction microphone, and a filter screen is fixedly installed on the barrier plate.

[0013] Preferably, a blocking plate is provided on one side of the filter screen, and two mounting plates are fixedly connected between the blocking plate and the mounting plate one. A guide frame is sleeved on the outside of the two mounting plates two, and the guide frame is fixedly connected to the bone conduction microphone.

[0014] Preferably, an ear hook is fixedly connected to one side of the connecting frame.

[0015] Preferably, there are two connecting frames, and a headband is fixedly connected between the two connecting frames.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In this application, a connecting frame can be quickly installed on one side of the bone conduction microphone. Depending on the headband or ear hook installed on one side of the connecting frame, the bone conduction microphone can enter different usage states. Furthermore, the connecting frame and the bone conduction microphone are installed together by bolts and multiple pins. Even if there is relative movement between the connecting frame and the bone conduction microphone, it is difficult for the bolts to rotate, thus ensuring the firmness of the installation between the bone conduction microphone and the connecting frame.

[0018] 2. In this application, there are two mounting plates 2 that are fixedly connected between the blocking plate and the mounting plate 1 in the sliding connection of the bone conduction microphone. When the mounting plate 1 moves, the blocking plate moves through the mounting plate 2. After the blocking plate moves, one side of the filter screen is no longer blocked, and external air can enter the bone conduction microphone, so that the bone conduction microphone enters the sound wave reception state.

[0019] 3. When using this application, control the rotation of the bolt. When one end of the bolt and one end of the multiple needle rods pass through the end of the insertion hole, stop operating the internal hexagonal fitting. At this time, the bolt and multiple needle rods are mostly located on the side of the U-shaped frame away from the U-shaped frame. The user can pass the parallel bolt and multiple needle rods through the clothing and hang the bone conduction microphone on the clothing. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example: Figures 1-7 As shown, this utility model provides a technical solution for a bone conduction silicon microphone, including a bone conduction microphone 1. A ventilation slot 17 is provided on one side of the bone conduction microphone 1. A U-shaped frame 1 2 and a U-shaped frame 2 3 are fixedly connected to one side of the bone conduction microphone 1. A connecting frame 20 and two plug-in plates 21 are provided between the U-shaped frame 1 2 and the U-shaped frame 2 3. A mounting plate 1 7 is provided inside the U-shaped frame 1 2. A bolt 8 is rotatably connected to the mounting plate 1 7. A nut 6 is threaded on the outside of the bolt 8. A plurality of pin rods 10 are fixedly connected to one side of the mounting plate 1 7. A sealing component is provided between the mounting plate 1 7 and the bone conduction microphone 1.

[0030] Specifically,

[0031] Example 1: Without the connector 20 installed, the bone conduction microphone 1 is an in-ear microphone, and the bone conduction microphone 1 achieves bone conduction effect by contacting the human body.

[0032] Example 2:

[0033] A plug-in plate 21 is fixedly installed at the top and bottom of the connecting frame 20. The plug-in plate 21 is hollow and has multiple plug holes 22 on one side of the connecting frame 20. After aligning the plug-in plate 21 with the gap between the U-shaped frame 2 and the U-shaped frame 3, the connecting frame 20 is pushed between the U-shaped frame 2 and the U-shaped frame 3. At this time, the two plug-in plates 21 and the multiple plug holes 22 correspond one-to-one with the multiple plug holes 13 on one side of the U-shaped frame 3.

[0034] Because a U-shaped guide groove 25 is provided inside the U-shaped frame 2, the mounting plate 7 inside the U-shaped frame 2 is inserted into the U-shaped guide groove 25, and the movement of the mounting plate 7 is limited and guided by the U-shaped guide groove 25; two storage slots 5 are provided on one side of the U-shaped frame 2, and the bolt 8 and nut 6 are both set inside one of the storage slots 5. The nut 6 is fixedly connected to the U-shaped frame 2, and the end of the bolt 8 away from the U-shaped frame 3 is fixedly connected to an internal hexagonal fitting 9. The internal hexagonal fitting 9 is set inside the storage slot 5 and is in contact with and fits against the U-shaped frame 2; one of the multiple needle rods 10 fixedly installed on the mounting plate 7 is set inside the other storage slot 5, and the support short shaft 11 fixedly connected to one end of the needle rod 10 is in contact with and fits against the U-shaped frame 2. Under the support of the internal hexagonal fitting 9 and the support short shaft 11, the mounting plate 7 moves horizontally under the guidance of the U-shaped guide groove 25.

[0035] Furthermore, a circular groove 4 is provided on one side of the U-shaped frame 2, and an internal hexagonal fitting 9 is provided on one side of the circular groove 4. After inserting an external hexagonal wrench into the internal hexagonal fitting 9 through the circular groove 4, rotating the external hexagonal wrench will cause the internal hexagonal fitting 9 and the bolt 8 fixedly connected to the internal hexagonal fitting 9 to rotate. The bolt 8 moves towards the U-shaped frame 2 3 under the action of the nut 6. The bolt 8 is rotatably connected to the mounting plate 1 7. The rotation of the bolt 8 is not affected by the mounting plate 1 7. The movement of the bolt 8 drives the mounting plate 1 7 to move synchronously, and the multiple pin bars 10 fixedly connected to the mounting plate 1 7 move synchronously.

[0036] After the operator controls the internal hexagonal component 9 to rotate for a period of time using an external hexagonal wrench, the operation is stopped, so that the needle bar 10 and the bolt 8 remain inside the socket 13 through the connector plate 21 and the second socket 22, but one end of the needle bar 10 and the bolt 8 does not move out of the socket 13. At this time, the bolt 8 and multiple needle bars 10 restrict the position of the connecting frame 20 and the connector plate 21, and fix the connecting frame 20 between the U-shaped frame 2 and the second U-shaped frame 3.

[0037] Example 3: Based on Example 2, if the connecting frame 20 is pre-fixed to one side by an ear hook 24, then the ear hook 24 and the bone conduction microphone 1 form an ear hook microphone.

[0038] Example 4: Based on Example 2, if the connecting frame 20 is one of the two connecting frames 20 that are fixedly connected to both ends of the headband 23, the other connecting frame 20 is installed with the other bone conduction microphone 1 using the same method, and the headband 23 can be worn on the head, so that the two bone conduction microphones 1 and the headband 23 form a headband microphone.

[0039] In summary, the bone conduction microphone 1 of this application can be quickly mounted on one side with a connecting bracket 20. Depending on the headband 23 or ear hook 24 mounted on one side of the connecting bracket 20, the bone conduction microphone 1 can enter different usage states. Furthermore, the connecting bracket 20 and the bone conduction microphone 1 are mounted together by bolts 8 and multiple pins 10. Even if there is relative movement between the connecting bracket 20 and the bone conduction microphone 1, it is difficult for the bolts 8 to rotate, thus ensuring the firmness of the installation between the bone conduction microphone 1 and the connecting bracket 20.

[0040] Example 5: Based on Example 2, when the mounting plate 7 moves, the barrier plate 19 in the sealed assembly is located inside the ventilation slot 17 of the bone conduction microphone 1 and is fixedly connected to the bone conduction microphone 1. A blocking plate 15 is provided on one side of the filter screen 18 fixedly installed on the barrier plate 19. Two mounting plates 14 are fixedly connected between the blocking plate 15 slidably connected to the bone conduction microphone 1 and the mounting plate 7. During the movement of the mounting plate 7, the blocking plate 15 is moved by the mounting plates 14. After the blocking plate 15 moves, one side of the filter screen 18 is partially unblocked, and external air can enter the bone conduction microphone 1, so that the bone conduction microphone 1 enters the sound wave reception state.

[0041] Guide frames 16 are fitted on the outer sides of the two mounting plates 14. The guide frames 16, which are fixedly connected to the bone conduction microphone 1, limit the movement of the mounting plates 14 and ensure the stability of the movement of the mounting plates 14 and the blocking plate 15.

[0042] Example 6:

[0043] Without installing the connecting bracket 20 between U-shaped frame 1 2 and U-shaped frame 2 3, the internal hexagonal wrench is used to control the rotation of the internal hexagonal component 9, causing the bolt 8 to rotate. When one end of the bolt 8 and one end of the multiple needle rods 10 have passed through the end of the insertion hole 13, the operation of the internal hexagonal component 9 is stopped. At this time, the bolt 8 and the multiple needle rods 10 are mostly located on the side of U-shaped frame 2 3 away from U-shaped frame 1 2. The user can pass the parallel bolt 8 and the multiple needle rods 10 through the clothing and hang the bone conduction microphone 1 on the clothing.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
