Description

Technical Field

[0001] This invention relates to the field of microphone technology, and more particularly to a telescopic directional microphone. Background Technology

[0002] In the field of modern audio acquisition, the microphone, as a core device, plays a direct and decisive role in audio quality. As application scenarios become increasingly diverse, such as professional recording studios, conference rooms, outdoor interviews, and live broadcasts, the requirements for microphone functionality are becoming increasingly stringent.

[0003] In terms of cleaning, the microphone grille, as the primary barrier for sound entry, easily attracts dust, hair, and other impurities from the air during daily use. Actual tests have shown that these impurities can increase sound attenuation by 20%-30%, turning originally clear sound into muffled and distorted sound. Currently, most microphones rely on manual cleaning, a method with many drawbacks. Manual cleaning requires users to periodically remove the microphone from the device and clean it with tools such as brushes and damp cloths. This process is cumbersome, and in practice, users often fail to clean it in a timely manner, thus affecting the microphone's normal performance.

[0004] Regarding angle adjustment, traditional microphones often employ simple angle adjustment methods with limited ranges, or require additional adjustment brackets. Taking a conference setting as an example, different speakers are positioned in different locations. Microphones with limited adjustment ranges struggle to capture the voice of each speaker flexibly and accurately. Microphones relying on additional adjustment brackets are not only time-consuming and labor-intensive to install and adjust, but may also be difficult to place effectively in space-constrained environments, ultimately leading to the loss or weakening of some sound signals. Summary of the Invention

[0005] To overcome the aforementioned drawbacks, the present invention provides a telescopic directional microphone.

[0006] The technical solution is as follows: A telescopic directional microphone includes a base, a controller, a stabilizing plate, a connecting block, a sleeve, a telescopic rod, and a socket block. The controller is installed on the left side of the base, and the stabilizing plate is installed on the top left side of the base. The connecting block is connected to the top of the stabilizing plate. The sleeve is rotatably connected to the connecting block, and the telescopic rod is slidably connected inside the sleeve. The socket block is rotatably connected to the right end of the telescopic rod. The microphone is snapped onto the socket block and electrically connected to the controller. The microphone also includes a support block, a hose, an air bladder, a one-way valve, an air tube, and a compression assembly. The front end of the connecting block and the front end of the socket block are respectively connected to the support block. A hose is connected between the support blocks. The upper end of the hose is connected to an annular air tube. The air tube is installed inside the microphone, and the nozzle of the air tube faces the microphone's mesh cover. An air bladder is connected to the middle of the bottom of the base. The lower end of the hose passes through the inside of the base and is connected and communicates with the air bladder. A one-way valve is connected to the top left side of the air bladder and passes through the top of the base. A compression assembly is provided inside the base.

[0007] Furthermore, the extrusion assembly includes an extrusion plate, a guide rod, and a tension spring. The guide rod is connected to the right side of the base, and the extrusion plates are slidably connected to both sides of the base. The extrusion plates are slidably connected to the guide rods. The extrusion plates are in close contact with the front and rear sides of the airbag. A tension spring is sleeved on the guide rod. The front and rear ends of the tension springs are connected to the extrusion plates on the same side, respectively. The top right end of the extrusion plate has an outward octagonal structure design, and the sleeve block abuts against the extrusion plates on both sides.

[0008] Furthermore, it also includes a second motor and a third motor. The second motor is connected to the left end of the sleeve. The second motor is a dual-axis motor. Its front and rear output shafts pass through the sleeve and are connected to the connecting block. The third motor is installed on the right end of the telescopic rod. The third motor is also a dual-axis motor. Its front and rear output shafts are both connected to the sleeve block. Both the second motor and the third motor are electrically connected to the controller.

[0009] Furthermore, it also includes a first motor, a rotating shaft, a magnet, a connecting ring, an elastic cord, and a tension spring. The first motor is installed on the left side inside the base and is electrically connected to the controller. The rotating shaft is coaxially connected to the output shaft of the first motor. Vertical grooves are opened on both sides inside the rotating shaft. A connecting ring is slidably connected in each groove. An elastic cord is connected to the top of each connecting ring. The top of the elastic cord passes through the top of the rotating shaft and is fixedly connected to the bottom of the stabilizing plate. A magnet is connected to the middle of the bottom of the stabilizing plate, and a magnet is also connected to the middle of the top of the rotating shaft. The two magnets are magnetically attracted to each other. A tension spring is fitted in each groove. The upper and lower ends of the tension spring are connected to the corresponding positions inside the connecting ring and the rotating shaft, respectively.

[0010] Furthermore, it also includes suction cups and piston plates. Suction cups are installed at the four corners of the bottom of the base. Independent chambers are set on the front and rear sides of the base. A piston plate is slidably connected in each chamber. Air holes are symmetrically opened on the left side wall of the base. These air holes are connected to the corresponding chambers. The piston plate is connected to the corresponding extrusion plate.

[0011] Furthermore, it also includes gears, locking teeth, and buffer springs. Gears are coaxially connected to the output shafts of both the second and third motors, and gears are also connected around the outside of the shafts. In the connecting block, symmetrical grooves are provided near the output shafts on both sides of the second motor, and locking teeth are slidably connected in the grooves. Each locking tooth is connected to the inside of the connecting block with a buffer spring. Similarly, in the sleeve block, symmetrical grooves are provided near the output shafts on both sides of the third motor, and locking teeth are slidably connected in the grooves. Each locking tooth is also connected to the inside of the sleeve block with a buffer spring. On the left side of the base, symmetrical grooves are also provided front and back near the output shaft of the first motor. Locking teeth are slidably connected in the grooves, and buffer springs are also connected to the inside of the base with the locking teeth. Each gear is equipped with two locking teeth that engage with it, and all locking teeth engage with the gears at the corresponding positions.

[0012] Furthermore, the part of the tooth that engages with the gear has beveled surfaces on both sides.

[0013] Furthermore, it also includes a protective sleeve, support rods, shock-absorbing springs, and dampers. Protective sleeves are connected to both the front and rear side walls of the base. Support rods are symmetrically and slidably connected to the bottom of the protective sleeves. A damper is installed on the upper side of each support rod. The telescopic end of the damper is connected to the corresponding position inside the protective sleeve. A shock-absorbing spring is fitted on each support rod. The upper and lower ends of the shock-absorbing spring are connected to the limiting boss on the support rod and the inner surface of the bottom of the protective sleeve, respectively.

[0014] The beneficial effects of this invention are as follows: 1. With the coordinated operation of the first, second and third motors, the microphone can be adjusted in all directions, including horizontal, forward and backward and vertical tilt angles, to adapt to various sound recording scenarios and accurately capture sound signals.

[0015] 2. Before using the microphone, the squeezing component operates automatically, squeezing the airbag to spray air onto the mesh cover, effectively removing dust and ensuring sound quality.

[0016] 3. Multiple structures work together to ensure stability. The suction cup automatically attaches to the platform and fixes the base. The elastic rope and tension spring work together to prevent the sleeve and telescopic rod from breaking due to collision. The locking teeth and gears work together to stabilize the microphone position.

[0017] 4. The protective sleeve, support rod, shock-absorbing spring and damper work together to effectively counteract the vertical vibration during use, reduce environmental interference, and ensure sound transmission stability.

[0018] 5. When manually adjusting the socket block, sleeve and connecting block, the cleat easily passes over the gear under the action of the buffer spring and the inclined plane, realizing convenient fine adjustment without the need for power components. Attached Figure Description

Detailed Implementation

[0031] The present invention will now be described in detail with reference to the accompanying drawings.

[0032] Example 1: A telescopic directional microphone, such as... Figures 1-7 As shown, the device includes a base 1, a controller 101, a stabilizing plate 102, a connecting block 103, a sleeve 104, a telescopic rod 105, a connecting block 106, a support block 201, a hose 202, an airbag 203, a one-way valve 204, an air tube 205, and a compression assembly. The controller 101 is mounted on the left side of the base 1, serving as the control center of the entire device for controlling and adjusting the microphone's functions. A stabilizing plate 102 is mounted on the top left side of the base 1. A connecting block 103 is connected to the top of the stabilizing plate 102. A sleeve 104 is rotatably connected to the connecting block 103. A telescopic rod 105 is slidably connected inside the sleeve 104. A connecting block 106 is rotatably connected to the right end of the telescopic rod 105. A microphone 107 is snapped onto the connecting block 106 and electrically connected to the controller 101. The front end of the connecting block 103 and the front end of the connecting block 106 are respectively connected... A support block 201 is connected to the base 1, and a flexible tube 202 is connected between the support blocks 201. The upper end of the flexible tube 202 is connected to an annular air tube 205. The air tube 205 is detachably installed inside the microphone 107, and the nozzle of the air tube 205 faces the mesh cover of the microphone 107 to achieve the function of cleaning the mesh cover of the microphone 107. An airbag 203 is connected to the middle of the bottom of the base 1. The lower end of the flexible tube 202 passes through the interior of the base 1 and is connected to and communicates with the airbag 203. A one-way valve 204 is connected to the top left of the airbag 203. The one-way valve 204 passes through the top of the base 1, and external air can enter the airbag 203 through the one-way valve 204, while the air inside the airbag 203 cannot be discharged through the one-way valve 204, thereby ensuring the one-way flow of air inside the airbag 203. A squeezing component is provided inside the base 1 to realize the squeezing operation of the airbag 203.

[0033] like Figure 4 , Figure 5 and Figure 7 As shown, the extrusion assembly includes an extrusion plate 301, a guide rod 302, and a tension spring 303. The guide rod 302 is welded to the right side of the base 1. The extrusion plate 301 is slidably connected to both the front and rear sides of the base 1. The extrusion plate 301 is slidably connected to the guide rod 302. The extrusion plate 301 is in close contact with the front and rear sides of the airbag 203 so as to effectively extrude the airbag 203. The tension spring 303 is sleeved on the guide rod 302. The front and rear ends of the tension spring 303 are respectively connected to the extrusion plate 301 on the same side. The top right end of the extrusion plate 301 has an outward octagonal structure design. The sleeve block 106 abuts against the extrusion plates 301 on both sides, and the tension spring 303 is in a stretched state.

[0034] like Figure 3As shown, it also includes a second motor 108 and a third motor 109. The second motor 108 is bolted to the left end of the sleeve 104. The second motor 108 is a dual-axis motor, and its front and rear output shafts pass through the sleeve 104 and are connected to the connecting block 103. The third motor 109 is bolted to the right end of the telescopic rod 105. The third motor 109 is also a dual-axis motor, and its front and rear output shafts are both connected to the sleeve block 106. The second motor 108 and the third motor 109 are both electrically connected to the controller 101.

[0035] During the use of the device, it is first placed on the platform. The microphone 107 can be turned on and off by the controller 101, thereby realizing the function of recording sound through the microphone 107. In the initial state, the microphone 107 is in a folded state. When it is necessary to lift the microphone 107, the controller 101 is operated to start the second motor 108. Since the output shaft of the second motor 108 is connected to the connecting block 103 and the main body of the second motor 108 is connected to the sleeve 104, the rotation of the output shaft of the second motor 108 will drive the main body and the sleeve 104 connected to it to rotate upward and stand up, thereby driving the telescopic rod 105, the connecting block 106 and the microphone 107 to lift upward. After being lifted to a suitable position, the second motor 108 can be turned off first. Then, according to the actual use needs, the telescopic rod 105 can be operated to slide up and down in the sleeve 104 to adjust the height of the telescopic rod 105, thereby adjusting the height position of the microphone 107. At the same time, the controller 101 can also be operated to start the third motor 109. Since the output shaft of the third motor 109 is connected to the socket block 106, the rotation of its output shaft can drive the socket block 106 and the microphone 107 to adjust the front and rear tilt angles, so that the angle of the microphone 107 can be accurately aligned with the speaker's mouth position to achieve the best sound reception effect. In the initial state, the socket block 106 presses down on the compression plate 301. When the socket block 106 rises with the telescopic rod 105, the tension spring 303, which was originally in a stretched state, loses its external force and rebounds to its original position, causing the compression plate 301 to move inward. During the inward movement of the compression plate 301, it compresses the airbag 203, causing the air inside the airbag 203 to enter through the hose 202 and flow into the air tube 205. Finally, the air is sprayed from the nozzle of the air tube 205 onto the microphone 107 mesh cover. The jetting action of the gas expels the dust adhering to the mesh cover, thus achieving the automatic cleaning function of the microphone 107 mesh cover before use. The hose 202 has... During the adjustment of the microphone 107 position, the flexible hose 202 does not restrict the movement of the sleeve 104 and the telescopic rod 105. After the microphone 107 is used, the controller 101 is operated again to activate the second motor 108 and the third motor 109, folding the microphone 107 back to its initial state. During this process, the socket block 106 will re-engage with the figure-eight structure on the right end of the compression plate 301. As the socket block 106 moves, it will push the compression plate 301 to move outward, and the tension spring 303 will be stretched accordingly. After the compression plate 301 moves outward, it will release the pressure on the airbag 203, and the airbag 203 will rebound and return to its original shape under its own elasticity. At the same time, during the rebound of the airbag 203, a negative pressure is formed inside, which will draw external air into the airbag 203 through the one-way valve 204 to store air for the next use, so as to achieve the cleaning function of the microphone 107 mesh again.

[0036] Example 2: Based on Example 1, such as Figure 3 and Figure 10 As shown, it also includes a first motor 1021, a rotating shaft 1022, a magnet 601, a connecting ring 602, an elastic pull rope 603, and a tension spring 604. The first motor 1021 is bolted to the left side of the base 1 and is electrically connected to the controller 101. The rotating shaft 1022 is coaxially connected to the output shaft of the first motor 1021. Vertical grooves are opened on the front and rear sides of the rotating shaft 1022. The connecting ring 602 is slidably connected in each groove. The top of the connecting ring 602 is connected to the top of the elastic pull rope 603, and the top of the elastic pull rope 603 extends through the top of the rotating shaft 1022. It is fixedly connected to the bottom of the stabilizing plate 102. A magnet 601 is welded to the middle of the bottom of the stabilizing plate 102, and a magnet 601 is also welded to the middle of the top of the rotating shaft 1022. The two magnets 601 are magnetically attracted to each other, thereby achieving a stable connection between the stabilizing plate 102 and the rotating shaft 1022. Each groove is fitted with a tension spring 604. The upper and lower ends of the tension spring 604 are connected to the corresponding positions inside the connecting ring 602 and the rotating shaft 1022, respectively. The tension spring 604 is in a slightly compressed state, which ensures that the elastic pull rope 603 has enough tension to stabilize the stabilizing plate 102.

[0037] When it is necessary to adjust the horizontal direction of the connecting block 103 and the sleeve 104, thereby adjusting the horizontal angle of the microphone 107, the controller 101 can be operated to start the first motor 1021. The output shaft of the first motor 1021 rotates, driving the connected rotating shaft 1022 to rotate synchronously. The rotating shaft 1022, through the attraction of two magnets 601, drives the stabilizing plate 102 and the connecting block 103 to rotate, thereby driving the sleeve 104, the telescopic rod 105, the connecting block 106, and the microphone 107 to rotate, realizing the adjustment of the horizontal orientation of the microphone 107. During the use of the microphone 107, the... Due to the relatively high height of the sleeve 104 and telescopic rod 105, the center of gravity of the device may be unstable. In the event of an accidental collision with the sleeve 104 and telescopic rod 105, the elastic cord 603 will play a crucial role. At this time, the stabilizing plate 102 will tilt at a certain angle on the rotating shaft 1022. The elastic deformation of the elastic cord 603 provides some room for movement for the stabilizing plate 102 and the microphone 107, while the elastic force of the tension spring 604 acts as a buffer and support, ensuring that the sleeve 104 and telescopic rod 105 will not tip over or break due to external forces. When the external force disappears, under the combined action of the attraction force of the magnet 601, the tension of the elastic cord 603, and the elastic force of the tension spring 604, the stabilizing plate 102 can return to its initial position and fit tightly against the rotating shaft 1022, ensuring that the device returns to a stable working state.

[0038] like Figure 5 and Figure 7As shown, it also includes suction cups 401 and piston plates 402. Suction cups 401 are installed at the four corners of the bottom of the base 1 to achieve a tight fit with the placement platform. Independent chambers are provided on the front and rear sides of the base 1. Each chamber is connected to the piston plate 402 in a sliding seal manner to ensure the airtightness of the chamber during the movement of the piston plate 402. Air holes 403 are symmetrically opened on the left side wall of the base 1. These air holes 403 are interconnected with the corresponding chambers to provide channels for the air to enter and exit the chambers. The piston plate 402 and the corresponding extrusion plate 301 are fixedly connected by rigid connectors to ensure that the two can move synchronously.

[0039] When using this device, first place the base 1 stably on the platform. At this time, the suction cup 401 is in close contact with the platform surface. When it is necessary to use the telescopic rod 105 and the sleeve 104 to lift the microphone 107 upwards for use, the socket block 106 will no longer press against the extrusion plate 301. The movement of the extrusion plate 301 will synchronously drive the piston plate 402 to move inwards. During the inward movement of the piston plate 402, a negative pressure will be formed between the suction cup 401 and the platform, drawing the air between them into the corresponding chamber. As the air is continuously drawn out, a vacuum state gradually forms between the suction cup 401 and the platform. The strong atmospheric pressure allows the suction cup 401 to adhere tightly to the platform, thereby achieving the lifting of the base 1. The automatic fixing significantly improves the overall stability of the device. Simultaneously, the air compressed by the piston plate 402 pushing inward is discharged to the outside through the air hole 403, ensuring the piston plate 402 can move normally within the chamber and avoiding obstruction due to air pressure issues. When the microphone 107 is finished and needs to be folded for storage, the sleeve block 106 is operated to re-press the compression plate 301, forcing the compression plate 301 to move outward. This movement of the compression plate 301 drives the piston plate 402 connected to it to move outward synchronously. During the outward movement of the piston plate 402, the air in the chamber is pushed back into the suction cup 401, breaking the vacuum between the suction cup 401 and the platform. At this time, the atmospheric pressure's adsorption effect on the suction cup 401 disappears, and the base 1 can be normally removed from the platform, facilitating the storage and reuse of the device.

[0040] like Figure 8 and Figure 9As shown, it also includes gears 501, locking teeth 502, and buffer springs 503. Gears 501 are coaxially connected to the output shafts of both the second motor 108 and the third motor 109. Gears 501 are also connected around the outside of the rotating shaft 1022. In the connecting block 103, symmetrical grooves are provided near the output shafts on both sides of the second motor 108. Locking teeth 502 are slidably connected in the grooves. Each locking tooth 502 is connected to the inside of the connecting block 103. Similarly, in the sleeve block 106, symmetrical grooves are provided near the output shafts on both sides of the third motor 109. Locking teeth 502 are slidably connected in the grooves. A buffer spring 503 is also connected between the tooth 502, the locking tooth 502 and the sleeve block 106. On the left side of the base 1, near the output shaft of the first motor 1021, there are also symmetrical sliding grooves. The locking tooth 502 is slidably connected in the sliding groove. The locking tooth 502 is also connected to the base 1. Each gear 501 is equipped with two locking teeth 502 to cooperate with it. All locking teeth 502 are engaged with the gear 501 at the corresponding position. The part of the locking tooth 502 that engages with the gear 501 has two beveled surfaces on both sides, which is conducive to the locking tooth 502 smoothly passing over the gear 501 under certain conditions.

[0041] During device operation, the operation of the first motor 1021 drives the rotating shaft 1022 to rotate, thereby adjusting the horizontal angle of the connecting block 103 and achieving synchronous adjustment of the horizontal angle of the microphone 107. The operation of the second motor 108 drives the sleeve 104 to rotate, thereby adjusting the front-to-back position of the sleeve 104 and the telescopic rod 105 as a whole. The third motor 109 drives the connecting block 106 to rotate, adjusting the vertical tilt angle of the connecting block 106 and the microphone 107. When the first motor 1021, the second motor 108, and the third motor 109 stop running, their output shafts are in a relaxed state. At this time, due to the engagement of the locking teeth 502 and the gear 501, the rotation of the gear 501 is effectively restricted, so that the position of the microphone 107 can be kept stable. This ensures that the position will not change due to slight external interference during use. If a slight adjustment of the position of the microphone 107 is required... At this time, the user can manually adjust the socket block 106, sleeve 104 and connecting block 103 individually without starting the first motor 1021, the second motor 108 and the third motor 109. When these components rotate, the locking teeth 502 can pass over the teeth of the gear 501 well under the elastic action of the buffer spring 503 and the structural characteristics of its own inclined surface. Specifically, when the external force applied manually causes the components to rotate, the locking teeth 502 are squeezed by the teeth of the gear 501, the buffer spring 503 is compressed, and the locking teeth 502 gradually slides upward along the inclined surface to pass over the teeth, thereby realizing slight manual adjustment. When these components stop rotating, the buffer spring 503 returns to its deformation and pushes the locking teeth 502 to re-engage with the gear 501. The locking teeth 502 can quickly and accurately embed into the tooth groove of the gear 501, providing good stability for the microphone 107 again and ensuring that the device can still work stably after manual adjustment.

[0042] like Figure 1 and Figure 11 As shown, the device also includes a protective sleeve 701, a support rod 702, a shock-absorbing spring 703, and a damper 704. Protective sleeves 701 are connected to both the front and rear side walls of the base 1. Support rods 702 are symmetrically and slidably connected to the bottom of the protective sleeve 701. These support rods 702 serve as the legs of the entire device, providing stable support on the platform. A damper 704 is installed on the upper side of each support rod 702. The telescopic end of the damper 704 is connected to the corresponding position inside the protective sleeve 701. A shock-absorbing spring 703 is fitted onto each support rod 702. The upper and lower ends of the shock-absorbing spring 703 are tightly connected to the limiting boss on the support rod 702 and the inner surface of the bottom of the protective sleeve 701, respectively, ensuring that the shock-absorbing spring 703 can function effectively.

[0043] During the use of the device, when vibrations occur due to external factors, the damping spring 703 and the damper 704 work together to counteract the vertical vibration forces. Specifically, when the device vibrates upwards, the base 1 and protective sleeve 701 slide upwards relative to the support rod 702. At this time, the damping spring 703 is compressed, storing the energy generated by the vibration and converting it into elastic potential energy. Simultaneously, the telescopic end of the damper 704 also contracts accordingly. The damping medium inside the damper 704 generates resistance, hindering the rapid contraction of the telescopic end, thereby consuming some vibration energy. When the device vibrates downwards, the base 1 and protective sleeve 701 slide downwards relative to the support rod 702. The damping spring 703 gradually recovers its deformation, releasing the previously stored elastic potential energy. The telescopic end of the damper 704 extends, and again, the resistance generated by the damping medium consumes some vibration energy, preventing the device from shaking significantly due to vibration.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
