Description

Technical Field

[0001] This utility model relates to the field of microphone technology, specifically to a microphone with shock absorption function. Background Technology

[0002] A microphone is an energy conversion device that converts sound signals into electrical signals. Microphones can be classified into dynamic, condenser, electret, and the recently emerging silicon micro-microphones. In addition, there are liquid microphones and laser microphones. Most microphones are electret condenser microphones, which work by using a polymer diaphragm with permanent charge isolation.

[0003] A search revealed Chinese Patent Publication No. CN219068327U, which discloses a microphone with a shock-absorbing structure. The microphone body includes a microphone shell and a base. The microphone shell has multiple connection ports, and one end of the shell has a grip connected to the base. The grip has a shock-absorbing component with an air outlet channel. A mounting cavity is located inside the grip, and a fan bracket is fixed within the cavity. A fan is fixed to the fan bracket. The grip has an air inlet and an air outlet, with a dustproof mesh fixed at the air inlet. A plug is located on the grip and inserts into the air outlet, connecting the air outlet and the air outlet channel. This novel microphone features a shock-absorbing base, making it more stable and durable when handled. However, the top of the microphone is typically a mesh structure, allowing dust from the air to enter and affect the internal components, thus impacting the sound quality. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a microphone with shock absorption function, which has the advantages of preventing dust from entering. It solves the problem that the top of the microphone is usually a mesh structure, and dust in the air enters the microphone from the top of the microphone, which will affect the components inside the microphone cavity and thus affect the microphone sound quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a microphone with shock absorption function, comprising a microphone body, an elastic pad covering the outer surface of the microphone body, a dust-blocking mesh covering the top of the microphone body, a replacement mechanism for easy replacement of the dust-blocking mesh on the top of both sides of the elastic pad, and a shock absorption mechanism for reducing the vibration of the microphone body on the lower surface of the microphone body.

[0006] The replacement mechanism includes cavities formed at the top of the left and right sides of the elastic pad. Threaded rods are rotatably connected to the upper and lower ends of the opposite sides of the inner walls of the cavities via bearings. The outer surfaces of the two threaded rods are threaded to the same movable plate. The two threaded rods are connected by a belt drive. A driven bevel gear is fixed to the outer surface of the lower threaded rod, and the driven bevel gear meshes with a driving bevel gear. A drive rod is fixed to the inner cavity of the driving bevel gear. Insertion blocks are fixed to the top of the opposite sides of the movable plates at both ends. Insertion slots are formed at the bottom of both sides of the ash-blocking mesh.

[0007] Furthermore, each of the elastic pads has a locking hole on its front side, and the size of the inner cavity of the locking hole is adapted to the buttons and display screen on the outer surface of the microphone body.

[0008] Furthermore, the cross-sectional shape of the dust-blocking mesh is inverted U-shaped, and a guide hole is provided on the upper surface of the cavity. The size of the inner cavity of the guide hole is adapted to the size of the movable plate.

[0009] Furthermore, a slider is fixed to the lower surface of the movable plate, and a groove is formed on the lower surface of the cavity, allowing the slider to move horizontally in the inner cavity of the groove.

[0010] Furthermore, the size of the inner cavity of the insertion slot is adapted to the size of the insertion block, and the left and right ends of the outer surface of the elastic pad are provided with fixing slots. The front of the drive rod passes through the fixing slot and extends into the inner cavity of the fixing slot and is fixed with a handle.

[0011] Furthermore, the shock absorption mechanism includes a rubber block fixed to the lower surface of the microphone body. The lower surface of the rubber block has three grooves, and a spring buffer rod is fixed to the inner top wall of the groove. A base is provided on the lower side of the rubber block, and the lower surface of the spring buffer rod is fixedly connected to the base.

[0012] Furthermore, limiting grooves are provided at both ends of the lower surface of the rubber block, and limiting sleeve rods are fixed on the side of the limiting grooves opposite to the base. The limiting sleeve rods are nested fixed rods and inner rods.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. This microphone with shock absorption function can block dust on the outer surface of the dust-blocking mesh, effectively preventing dust from entering the microphone and reducing its impact on sound quality. The included replacement mechanism allows users to easily replace the dust-blocking mesh regularly, protecting the lifespan of the microphone itself.

[0015] 2. This microphone with shock absorption function has a base on the lower surface of the microphone body. The base can be used to place the microphone body stably. The combination of rubber blocks and spring buffer rods can effectively isolate and buffer the vibration of the microphone body, preventing the microphone body from making a loud noise when placed on the table, and avoiding discomfort to the surrounding people.

Detailed Implementation

[0021] 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.

[0022] Please see Figure 1 In this embodiment, a microphone with shock absorption function includes a microphone body 1. An elastic pad 2 is fitted on the outer surface of the microphone body 1. A dust-blocking mesh 3 is provided on the top outer surface of the microphone body 1. The top of both sides of the elastic pad 2 is provided with a replacement mechanism 4 for easy replacement of the dust-blocking mesh 3. A shock-absorbing mechanism 5 is provided on the lower surface of the microphone body 1 for reducing the vibration of the microphone body 1.

[0023] The elastic pad 2 has a card hole on its front side. The size of the inner cavity of the card hole is adapted to the button and display screen on the outer surface of the microphone body 1. The cross-sectional shape of the dust blocking mesh 3 is inverted U-shaped. The dust blocking mesh 3 is made of nanomaterial. By setting the dust blocking mesh 3, dust can be blocked on the outer surface of the dust blocking mesh 3, which can effectively prevent dust in the air from entering and thus avoid affecting the sound quality of the microphone.

[0024] Please see Figure 2 To facilitate the user's periodic replacement of the dust-blocking mesh 3, the replacement mechanism 4 in this embodiment includes cavities 401 located at the top of the left and right sides of the elastic pad 2. The upper and lower ends of the opposite sides of the left and right walls of the cavity 401 are rotatably connected to threaded rods 402 via bearings. The outer surfaces of the two threaded rods 402 are threadedly connected to the same movable plate 403. The two threaded rods 402 are connected by a belt drive. A driven bevel gear 404 is fixed to the outer surface of the lower threaded rod 402. The rotation of the driven bevel gear 404 causes the lower threaded rod 402 to rotate. The rotation of the lower threaded rod 402 can be driven by the belt to rotate the upper threaded rod 402. The threaded rod 402 rotates, and the rotation of the two threaded rods 402 causes the movable plate 403 threadedly connected to its surface to move. The driven bevel gear 404 meshes with the driving bevel gear 405. The inner cavity of the driving bevel gear 405 is fixed with a drive rod 406, which can rotate. The rotation of the drive rod 406 drives the rotation of the driving bevel gear 405. The rotation of the driving bevel gear 405 causes the driven bevel gear 404 meshing with its surface to rotate. The top of the movable plates 403 at both ends of the left and right ends is fixed with a plug-in block 407. The bottom of both sides of the dust blocking mesh 3 is provided with a plug-in groove 408.

[0025] The upper surface of the cavity 401 is provided with a guide hole, the size of which is adapted to the size of the movable plate 403. A slider is fixed on the lower surface of the movable plate 403, and a groove is provided on the lower surface of the cavity 401. The slider moves horizontally in the inner cavity of the groove. The slider fixed at the bottom of the movable plate 403 moves to the left in the inner cavity of the groove, which can limit the movement of the movable plate 403, so that the movable plate 403 can only move in a straight line.

[0026] In this embodiment, the size of the inner cavity of the insertion slot 408 is adapted to the size of the insertion block 407. Fixing slots are provided at both ends of the outer surface of the elastic pad 2. The front of the drive rod 406 passes through the fixing slot and extends into the inner cavity of the fixing slot and is fixed with a handle.

[0027] It is understandable that when the movable plate 403 moves, its top moves within the cavity of the guide hole, and drives the plug-in block 407 to move until the two plug-in blocks 407 are pulled out from the cavity of the plug-in slot 408 on the left and right sides of the dust blocking mesh 3. This releases the limit on the dust blocking mesh 3, allowing the dust blocking mesh 3 to be removed and replaced, thus protecting the service life of the microphone body 1.

[0028] Please see Figures 3 to 4 To prevent the microphone body 1 from making a loud noise when placed on the table, the shock absorption mechanism 5 in this embodiment includes a rubber block 501 fixed to the lower surface of the microphone body 1. The lower surface of the rubber block 501 has three grooves 502. A spring buffer rod 503 is fixed to the inner top wall of the groove 502. A base 504 is provided on the lower side of the rubber block 501. The lower surface of the spring buffer rod 503 is fixedly connected to the base 504. The microphone body 1 is placed on the table through the base 504. When the base 504 contacts the table, the base 504 will exert an upward force on the spring buffer rod 503, causing the spring buffer rod 503 to shorten, which can be used to absorb and disperse the impact force.

[0029] The rubber block 501 has limit grooves at both ends of its lower surface. Limiting sleeve rods are fixed on the side of the limit grooves that are opposite to the base 504. The limiting sleeve rods are nested fixed rods and inner rods.

[0030] Understandably, the rubber block 501 can absorb the impact force, making the impact force transmitted to the microphone body 1 smaller and preventing damage to the microphone body 1. Then, the spring buffer rod 503 rebounds and moves the base 504 downward, which can stabilize the microphone body 1 on the table. This achieves effective isolation and buffering of the vibration of the microphone body 1, preventing the microphone body 1 from making a loud noise when placed on the table, and avoiding discomfort to the surrounding people.

[0031] The working principle of the above embodiments is as follows:

[0032] (1) The dust-blocking mesh 3 can block dust on its outer surface, effectively preventing dust from entering and thus avoiding affecting the microphone's sound quality. To facilitate the periodic replacement of the dust-blocking mesh 3, the drive rod 406 can be rotated during replacement. The rotation of the drive rod 406 drives the rotation of the active bevel gear 405. The rotation of the active bevel gear 405 causes the driven bevel gear 404 meshing with its surface to rotate. The rotation of the driven bevel gear 404 causes the lower threaded rod 402 to rotate. The rotation of the lower threaded rod 402 can be driven by a belt to rotate the upper threaded rod. The threaded rod 402 rotates, causing the movable plate 403, which is threadedly connected to its surface, to move. At this time, the slider fixed at the bottom of the movable plate 403 moves to the left in the inner cavity of the slide groove, which limits the movement of the movable plate 403, so that the movable plate 403 can only move in a straight line. When the movable plate 403 moves, its top moves in the inner cavity of the guide hole, and drives the plug-in block 407 to move until the two plug-in blocks 407 are pulled out from the inner cavity of the plug-in groove 408 on the left and right sides of the dust blocking mesh 3. This releases the limitation on the dust blocking mesh 3, so that the dust blocking mesh 3 can be removed and replaced.

[0033] (2) After the user uses the microphone body 1, the microphone body 1 can be placed on the table through the base 504. When the base 504 contacts the table, the base 504 will generate an upward force on the spring buffer rod 503, which will shorten the spring buffer rod 503 and can be used to absorb and disperse the impact force. Then the rubber block 501 can absorb the impact force, so that the impact force transmitted to the microphone body 1 is smaller, and the microphone body 1 is not damaged. Then the spring buffer rod 503 rebounds and the base 504 moves downward, which can stabilize the microphone body 1 on the table.
