Description

Technical Field

[0001] The present invention relates to the technical field of microphones, and particularly to a microphone with telescopic directional sound pickup. Background Art

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

[0003] In terms of cleaning, the microphone grille, as the primary gateway for sound to enter, is extremely prone to adsorbing impurities such as dust and hair in the air during daily use. Through actual tests, these impurities can cause the attenuation of sound during transmission to increase by 20%-30%, making the originally clear sound become blurred and distorted. Currently, the vast majority of microphones rely on manual cleaning, which has many drawbacks. Manual cleaning requires users to regularly disassemble the microphone from the device and then use tools such as brushes and wet cloths for cleaning. This operation process is cumbersome, and in actual use, there are often situations where users fail to clean it in a timely manner, thereby affecting the normal performance of the microphone.

[0004] In terms of angle adjustment, traditional microphones mostly adopt a simple angle adjustment method with a limited adjustment range or require an additional adjustment bracket. Taking the conference scenario as an example, different speakers are located in different positions. For microphones with a limited adjustment range, it is difficult to flexibly and accurately capture the voices of each speaker. For microphones that rely on additional adjustment brackets, not only are they time-consuming and laborious during installation and adjustment, but in some environments with limited space, they may not be effectively arranged, ultimately resulting in the loss or weakening of some sound signals. Summary of the Invention

[0005] In order to overcome the above-mentioned drawbacks, the present invention provides a microphone with telescopic directional sound pickup.

[0006] The technical solution is as follows: A telescopic and directionally sound-picking microphone includes a base, a controller, a stabilizing plate, a connecting block, a sleeve, a telescopic rod, and a socket block.

The right end of the telescopic rod is rotatably connected to the socket block. The microphone is clamped on the socket block and electrically connected to the controller. It further includes a support block, a hose, an airbag, a one-way valve, an air pipe, and an extrusion assembly. The front ends of the connecting block and the socket block are respectively connected to the support block. The hose is connected between the support blocks. The upper end of the hose is connected to an annular air pipe. The air pipe is installed inside the microphone, and the nozzle of the air pipe faces the mesh cover of the microphone. The middle of the inner bottom of the base is connected to the airbag. The lower end of the hose penetrates through the inside of the base and is connected and communicated with the airbag.

The front and rear ends of the tension spring are respectively connected to the extrusion plates on the same side. The right end of the top of the extrusion plate is designed with an outwardly flared structure. The socket block abuts against the extrusion plates on both sides.

[0008] Furthermore, it further includes a second motor and a third motor. The second motor is connected to the left end inside the sleeve. The second motor is a double-shaft motor, and its output shafts on the front and rear sides penetrate through the sleeve and are connected to the connecting block. The third motor is installed at the right end of the telescopic rod. The third motor is also a double-shaft motor, and its output shafts on the front and rear sides are both connected to the socket block. The second motor and the third motor are both electrically connected to the controller.

[0009] Furthermore, it further includes a first motor, a rotating shaft, a magnet, a connecting ring, an elastic pull rope, and a tension spring. The first motor is installed on the left side inside the base and is electrically connected to the controller. The output shaft of the first motor is coaxially connected to the rotating shaft. Vertical sliding grooves are opened on both sides inside the rotating shaft. Connecting rings are slidably connected to the sliding grooves. Elastic pull ropes are connected to the tops of the connecting rings. The tops of the elastic pull ropes penetrate through the top of the rotating shaft and are fixedly connected to the bottom of the stabilizing plate. A magnet is connected to the middle of the bottom of the stabilizing plate. A magnet is also connected to the middle of the top of the rotating shaft. The two magnets are magnetically adsorbed to each other. Tension springs are sleeved in the sliding grooves. The upper and lower ends of the tension spring are respectively connected to the connecting ring and the corresponding positions inside the rotating shaft.

[0010] Furthermore, it further includes suction cups and piston plates. Suction cups are installed at the four corners of the bottom of the base. Independent chambers are respectively arranged on the front and rear sides inside the base. Piston plates are slidably connected to each chamber. Air holes are symmetrically opened on the left side wall of the base. These air holes are respectively communicated with the corresponding chambers. The piston plates are connected to the corresponding extrusion plates.

[0011] Further, it also includes gears, engaging teeth, and buffer springs. Gears are coaxially connected to the output shafts of the second motor and the third motor, and gears are also circumferentially connected to the outer side of the rotating shaft. Inside the connecting block, chutes are symmetrically arranged respectively near the output shafts on both sides of the second motor. Engaging teeth are slidably connected inside the chutes, and buffer springs are connected between each engaging tooth and the inside of the connecting block. Similarly, inside the socket block, chutes are symmetrically arranged respectively near the output shafts on both sides of the third motor. Engaging teeth are slidably connected inside the chutes, and buffer springs are also connected between the engaging teeth and the inside of the socket block. Inside the left side of the base, chutes are symmetrically arranged before and after near the output shaft of the first motor. Engaging teeth are slidably connected inside the chutes, and buffer springs are also connected between the engaging teeth and the inside of the base. Each gear is equipped with two engaging teeth to cooperate with it, and all the engaging teeth are engaged with the gears at the corresponding positions.

[0012] Further, the two sides of the part of the engaging tooth that is engaged with the gear are designed as inclined planes.

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

[0014] Advantages of the present invention: 1. With the coordinated operation of the first, second, and third motors, the microphone can achieve full-range adjustment in horizontal, front-back, and up-down tilt angles, adapt to diverse sound collection scenarios, and accurately capture sound signals.

[0015] 2. Before the microphone is used, the extrusion assembly automatically operates, and the extrusion airbag sprays air to the mesh cover to efficiently remove dust and ensure the sound collection quality.

[0016] 3. The combined action of multiple structures ensures stability. The suction cup automatically adsorbs the platform to fix the base. The elastic pull rope and the tension spring cooperate to prevent the sleeve and the telescopic rod from breaking due to collision and tipping. The engaging teeth and the gear cooperate to stably position the microphone.

[0017] 4. The protective sleeve, support rod, shock-absorbing spring, and damper work together to effectively offset the up-and-down vibrations during the use of the device, reduce environmental interference, and ensure the stability of sound transmission.

[0018] 5. When manually adjusting the socket block, the sleeve, and the connecting block, the engaging teeth can easily cross over the gear under the action of the buffer spring and the inclined plane, achieving convenient fine adjustment without the assistance of power components.

Detailed implementation manners

[0031] The present invention will be specifically described below in conjunction with the accompanying drawings.

[0032] Embodiment 1: A telescopic and directionally sound-pickup microphone, as Figures 1-7 shown, includes a base 1, a controller 101, a stabilizing plate 102, a connecting block 103, a sleeve 104, a telescopic rod 105, a socket block 106, a support block 201, a hose 202, an airbag 203, a one-way valve 204, an air pipe 205, and an extrusion assembly. A controller 101 is installed on the left side of the base 1, serving as the control center of the entire device for controlling and adjusting the related functions of the microphone. A stabilizing plate 102 is installed on the top left side of the base 1. The stabilizing plate 102 is connected to a connecting block 103 at the top. The connecting block 103 is rotatably connected to a sleeve 104. A telescopic rod 105 is slidably connected inside the sleeve 104. The right end of the telescopic rod 105 is rotatably connected to a socket block 106. A microphone 107 is snap-connected to the socket block 106 and is electrically connected to the controller 101. Support blocks 201 are respectively connected to the front ends of the connecting block 103 and the socket block 106. A hose 202 is connected between the support blocks 201. The upper end of the hose 202 is connected to an annular air pipe 205. The air pipe 205 is detachably installed inside the microphone 107, and the nozzle of the air pipe 205 faces the mesh cover of the microphone 107 to achieve the cleaning function of the mesh cover of the microphone 107. The middle of the inner bottom of the base 1 is connected to an airbag 203. The lower end of the hose 202 penetrates through the inside of the base 1 and is connected and communicated with the airbag 203. A one-way valve 204 is connected to the top left side of the airbag 203. The one-way valve 204 penetrates 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, thus ensuring the one-way flow of air inside the airbag 203. An extrusion assembly is provided inside the base 1 for performing an extrusion operation on the airbag 203.

[0033] As Figure 4 , Figure 5 and Figure 7 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 inside the base 1. The extrusion plates 301 are slidably connected to the front and rear sides inside the base 1. The extrusion plates 301 are slidably connected to the guide rod 302. The extrusion plates 301 are in close contact with the front and rear sides of the airbag 203 to effectively extrude the airbag 203. A 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 plates 301 on the same side. The right end of the top of the extrusion plate 301 is designed with an outwardly flared structure. The socket block 106 abuts against the two extrusion plates 301, and the tension spring 303 is in a stretched state.

[0034] As Figure 3As shown, it further includes a second motor 108 and a third motor 109. The left end inside the sleeve 104 is bolted with the second motor 108. The second motor 108 is a dual-axis motor, and the output shafts on its front and rear sides penetrate through the sleeve 104 and are connected to the connecting block 103. The right end of the telescopic rod 105 is bolted with the third motor 109. The third motor 109 is also a dual-axis motor, and the output shafts on its front and rear sides are both connected to the socket 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, first place it on the platform. The microphone 107 can be turned on and off through the controller 101, thus realizing the function of receiving 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, operate the controller 101 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 part and the connected sleeve 104 to rotate upward and stand up, thereby driving the telescopic rod 105, the socket block 106 and the microphone 107 to lift upward. After lifting to the appropriate position, the second motor 108 can be turned off first. Then, according to the actual use requirements, the telescopic rod 105 can be slid up and down in the sleeve 104 by operation, so as to adjust the height of the telescopic rod 105, and further adjust 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 inclination angles, so that the angle of the microphone 107 can be accurately aligned with the mouth position of the speaker to achieve the best sound reception effect. In the initial state, the socket block 106 presses the pressing plate 301. When the socket block 106 stands up with the telescopic rod 105, the tension spring 303 that was originally in a stretched state loses the external force, and then rebounds and resets, driving the pressing plate 301 to move inward. During the process of the pressing plate 301 moving inward, it will squeeze the airbag 203, so that the air in the airbag 203 enters and circulates into the trachea 205 through the hose 202, and finally sprays from the nozzle of the trachea 205 onto the mesh cover of the microphone 107. The dust attached to the mesh cover is discharged outward through the jet action of the gas, thereby realizing the automatic cleaning function of the mesh cover of the microphone 107 before use. The hose 202 is elastic, and during the process of adjusting the position of the microphone 107, the hose 202 will not limit the movement of the sleeve 104 and the telescopic rod 105. When the microphone 107 is used up, operate the controller 101 to start the second motor 108 and the third motor 109 again to fold the microphone 107 back to the initial state. During this process, the socket block 106 will come into contact with the eight-shaped structure at the right end of the pressing plate 301 again. As the socket block 106 moves, it will push the pressing plate 301 to move outward, and the tension spring 303 will be stretched accordingly. After the pressing plate 301 moves outward, it will release the extrusion of the airbag 203, and the airbag 203 will rebound and return to its original state under its own elastic action. At the same time, during the rebound process of the airbag 203, a negative pressure is formed inside it, and the external air will be pumped into the airbag 203 through the one-way valve 204 to store air for the next use, so as to realize the cleaning function of the mesh cover of the microphone 107 again.

[0036] Embodiment 2: On the basis of Embodiment 1, asFigure 3 and Figure 10 As shown in Figure 10 , it further includes a first motor 1021, a rotating shaft 1022, a magnet 601, a connecting ring 602, an elastic drawstring 603 and a tension spring 604. The first motor 1021 is installed on the left side inside the base 1 by bolts and is electrically connected to the controller 101. The output shaft of the first motor 1021 is coaxially connected with the rotating shaft 1022. Vertical chutes are provided on the front and rear sides inside the rotating shaft 1022, and the connecting rings 602 are slidably connected to the chutes. Elastic drawstrings 603 are connected to the tops of the connecting rings 602. The tops of the elastic drawstrings 603 penetrate through the top of the rotating shaft 1022 and are 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 adsorbed to each other to achieve the stable connection between the stabilizing plate 102 and the rotating shaft 1022. Tension springs 604 are sleeved in the chutes, and the upper and lower ends of the tension springs 604 are connected to the corresponding positions inside the connecting rings 602 and the rotating shaft 1022 respectively, and the tension springs 604 are in a slightly compressed state, which ensures that the elastic drawstrings 603 have enough tension to stabilize the stabilizing plate 102.

[0037] When it is necessary to adjust the connecting block 103 and the sleeve 104 horizontally to adjust 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 drives the stabilizing plate 102 and the connecting block 103 to rotate through the adsorption of the two magnets 601, so as to drive the sleeve 104, the telescopic rod 105, the socket 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, since the heights of the sleeve 104 and the telescopic rod 105 are relatively high, the center of gravity above the device may be unstable. If the sleeve 104 and the telescopic rod 105 are accidentally collided, the elastic drawstring 603 will play an important role. At this time, the stabilizing plate 102 will have a certain angular inclination change on the rotating shaft 1022. The elastic deformation of the elastic drawstring 603 provides a certain amount of movement space for the stabilizing plate 102 and the microphone 107, while the elastic force of the tension spring 604 can play a buffering and supporting role to ensure that the sleeve 104 and the telescopic rod 105 will not fall and break due to external forces. When the external force disappears, under the combined action of the adsorption force of the magnet 601, the tension of the elastic drawstring 603 and the elastic force of the tension spring 604, the stabilizing plate 102 can return to the initial position and fit tightly with the rotating shaft 1022, ensuring that the device returns to a stable working state.

[0038] As Figure 5 and Figure 7As shown, it also includes a suction cup 401 and a piston plate 402. Suction cups 401 are installed at the four corners of the bottom of the base 1 for achieving a tight fit with the placement platform. Independent chambers are respectively arranged on the front and rear sides of the base 1. A piston plate 402 is connected to each chamber in a sliding and sealing 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 respectively communicated with the corresponding chambers to provide channels for the air in and out of the chamber. The piston plate 402 is fixedly connected to the corresponding extrusion plate 301 by a rigid connector to ensure that the two can move synchronously.

[0039] When using the device, first place the base 1 steadily on the platform. At this time, the suction cup 401 is in close contact with the surface of the platform. When the telescopic rod 105 and the sleeve 104 need to drive the microphone 107 to stand up and put it into use, the sleeve block 106 will no longer press against the extrusion plate 301 with this action. The movement of the extrusion plate 301 will simultaneously drive the piston plate 402 to move inward. During the process of the piston plate 402 moving inward, a negative pressure will be formed between the suction cup 401 and the platform, and the air between the two will be sucked into the corresponding chamber. As the air is continuously sucked away, a vacuum state is gradually formed between the suction cup 401 and the platform. The strong atmospheric pressure enables the suction cup 401 to be tightly adsorbed on the platform, thereby achieving the base 1 The automatic fixation significantly improves the overall stability of the device. At the same time, the air pushed inward by the piston plate 402 will be discharged to the outside through the air hole 403, ensuring that the piston plate 402 can move normally in the chamber and avoid obstacles caused by air pressure problems. When the microphone 107 is used and needs to be folded and stored, the sleeve block 106 is operated to re-press the extrusion plate 301, forcing the extrusion plate 301 to move outward. The movement of the extrusion plate 301 will drive the piston plate 402 connected thereto to move outward synchronously. In the process of the piston plate 402 moving outward, the air in the chamber will be pushed back into the suction cup 401, destroying the vacuum state between the suction cup 401 and the platform. At this time, the adsorption effect of atmospheric pressure on the suction cup 401 disappears, and the base 1 can be normally removed from the platform, which is convenient for the storage and re-movable use of the device.

[0040] like Figure 8 and Figure 9As shown in the figure, it further includes a gear 501, a locking tooth 502 and a buffer spring 503. Gears 501 are coaxially connected to the output shafts of the second motor 108 and the third motor 109, respectively. The outer side of the rotating shaft 1022 is also surrounded and connected with a gear 501. Inside the connecting block 103, chutes are symmetrically arranged at positions close to the output shafts on both sides of the second motor 108. Locking teeth 502 are slidably connected in the chutes. A buffer spring 503 is connected between each locking tooth 502 and the inside of the connecting block 103. Similarly, inside the socket block 106, chutes are symmetrically arranged at positions close to the output shafts on both sides of the third motor 109. Locking teeth 502 are slidably connected in the chutes. Buffer springs 503 are also connected between the locking teeth 502 and the inside of the socket block 106. Inside the left side of the base 1, chutes are symmetrically arranged before and after at a position close to the output shaft of the first motor 1021. Locking teeth 502 are slidably connected in the chutes. A buffer spring 503 is also connected between the locking teeth 502 and the inside of the base 1. Each gear 501 is equipped with two locking teeth 502 for cooperation. All the locking teeth 502 are engaged with the gears 501 at corresponding positions. The two sides of the part of the locking tooth 502 engaged with the gear 501 are designed as inclined planes, which is beneficial for the locking tooth 502 to smoothly cross the gear 501 under specific circumstances.

[0041] During the operation of the device, the operation of the first motor 1021 can drive the rotation of the rotating shaft 1022, thereby adjusting the horizontal angle of the connecting block 103 and synchronously adjusting the horizontal angle of the microphone 107; the operation of the second motor 108 can drive the rotation of the sleeve 104, thereby adjusting the front and rear positions of the overall sleeve 104 and the telescopic rod 105, and the third motor 109 can drive the rotation of the socket block 106 to adjust the up and down inclination angle between the socket block 106 and the microphone 107. When the first motor 1021, the second motor 108 and the third motor 109 stop operating, their output shafts are in a relaxed state. At this time, due to the engagement between the locking teeth 502 and the gear 501, the rotation of the gear 501 can be effectively restricted, so that the position of the microphone 107 can be in a stable state, ensuring 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, the user can manually adjust the socket block 106, the sleeve 104 and the 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 well cross over the teeth of the gear 501 under the elastic action of the buffer spring 503 and the structural characteristics of its own inclined plane. Specifically, when an external force manually applied 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 slide upward along the inclined plane to cross over the teeth, thereby realizing a slight manual adjustment. After these components stop rotating, the buffer spring 503 restores its deformation and pushes the locking teeth 502 to engage with the gear 501 again. The locking teeth 502 can quickly and accurately engage into the tooth grooves 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] As Figure 1 and Figure 11 shown, it further 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. The bottom of the protective sleeve 701 is symmetrically and slidably connected to the support rods 702 on the left and right. These support rods 702 serve as the feet of the entire device and can stably support on the platform. A damper 704 is installed on the upper side of each support rod 702, and the telescopic end of the damper 704 is connected to the corresponding position inside the protective sleeve 701. A shock-absorbing spring 703 is sleeved on each support rod 702, and 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 effectively play its role.

[0043] During the use of the device, when vibrations occur due to external factors, the shock-absorbing spring 703 and the damper 704 will work together to counteract the vibration force in the up and down directions. Specifically, when the device generates an upward vibration, the base 1 and the protective sleeve 701 will slide upward relative to the support rod 702. At this time, the shock-absorbing spring 703 is compressed, and it will store the energy generated by the vibration and convert it into elastic potential energy. At the same time, the telescopic end of the damper 704 will also contract accordingly, and the damping medium inside the damper 704 will generate resistance to hinder the rapid contraction of the telescopic end, thereby consuming a part of the vibration energy. When the device generates a downward vibration, the base 1 and the protective sleeve 701 will slide downward relative to the support rod 702, and the shock-absorbing spring 703 will gradually recover its deformation and release the previously stored elastic potential energy. The telescopic end of the damper 704 will extend, and similarly, the resistance generated by the damping medium will consume a part of the vibration energy to prevent the device from shaking significantly due to vibration.
