[0002] A microphone, also known as a transducer or microphone, is an energy conversion device that converts sound signals into electrical signals. A directional microphone is a type of sound pickup device that is directionally selective and is specifically designed to accurately capture sound from a specific direction while suppressing background noise from other directions.

[0003] For example, utility model CN213186460U discloses a microphone with adjustable directionality. This utility model controls the rotation of a rotating column through multiple rotating components, allowing the rotating column to rotate at a certain angle, ranging from 0° to 45°. The rotation of the pickup element is indirectly controlled by the rotating column, allowing the pickup element to rotate and adjust the pickup direction, thereby improving the pickup effect. However, it can usually only adjust the orientation of the pickup element, and it is not convenient to adjust its pickup tilt angle, resulting in certain limitations in pickup. Utility Model Content

[0004] The purpose of this invention is to provide a microphone with an adjustable pickup angle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable microphone, comprising a directional microphone body and an adjustment component.

The output shaft of the first motor is connected to the worm gear, and the worm gear is engaged with a worm wheel on one side. The adjustment shaft is fixed inside the worm wheel.

[0006] Furthermore, the adjusting shaft is fixedly connected to the support frame, and the adjusting shaft is rotatably connected to the side plate.

[0007] Furthermore, a steering assembly is connected to the bottom of the side plate, and the steering assembly includes a base plate and a connecting sleeve. The base plate is fixed to the bottom of the side plate, and the connecting sleeve is installed at the bottom outer end of the base plate.

[0008] Furthermore, the steering assembly also includes a base and a second motor, with the base rotatably connected to the inside of the connecting sleeve, and the second motor housed inside the upper end of the base.

[0009] Furthermore, the steering assembly also includes a gear and a gear ring, the output shaft of the second motor is connected to the gear, and a gear ring meshes with one side of the gear, and the gear ring is fixedly connected to the base plate.

[0010] Furthermore, a limiting groove is provided on the inner side of the bracket, and a protrusion is slidably connected inside the limiting groove, and the protrusion is fixedly connected to the directional microphone body.

[0011] Furthermore, a positioning component is provided on the top of the directional microphone body, and the positioning component includes a fixing ear, a pin, a lever, and a compression spring.

[0013] This invention provides a microphone with an adjustable pickup angle, which has the following advantages:

[0014] 1. By adjusting the components, this utility model allows for precise pickup of the directional microphone body when the pickup angle needs to be adjusted. The first motor drives the worm gear to rotate, which in turn drives the adjustment shaft to rotate, thus adjusting the pitch angle of the directional microphone body. In conjunction with the second motor, the base plate is rotated via gears and a gear ring to change the orientation of the directional microphone body. This enables precise pickup of sound at a specific angle, further expanding the range of applications of the device. Furthermore, the self-locking structure of the worm gear and worm wheel can improve the stability after adjustment.

[0015] 2. This utility model, through the setting of the positioning component, allows the pin to avoid the support frame when the toggle is moved during assembly. At this time, the limiting groove and the protrusion quickly limit the position between the support frame and the directional microphone body. After releasing the toggle, the compression spring will push the toggle under the limiting of the fixing ear, causing the pin to be inserted into the positioning hole, quickly assembling the directional microphone body and the support frame. Similarly, when storing, the pin can be separated from the positioning hole simply by moving the toggle, so that no other tools are needed during disassembly, improving the convenience of use.

The adjustment component 3 is located on one side of the support frame 2 and includes a side plate 301, a side cover 302, a first motor 303, a worm gear 304, a worm wheel 305, and an adjustment shaft 306. The side cover 302 is mounted on one side of the side plate 301, and the first motor 303 is fixed to the bottom of the side cover 302. The output shaft of the first motor 303 is connected to... A worm gear 304 is provided, with a worm wheel 305 meshing on one side. The self-locking structure of the worm gear 304 and worm wheel 305 improves stability after adjustment. An adjusting shaft 306 is fixed inside the worm wheel 305. The adjusting shaft 306 is fixedly connected to the support frame 2 and rotatably connected to the side plate 301. When it is necessary to adjust the pickup angle of the directional microphone body 1, the first motor 303 can drive the worm gear 304 to rotate, which in turn causes the worm wheel 305 to drive the adjusting shaft 306 to rotate, thus adjusting the directional microphone's pickup angle. The tilt angle of the microphone body 1 is adjustable. A steering assembly 4 is connected to the bottom of the side plate 301. The steering assembly 4 includes a base plate 401 and a connecting sleeve 402. The base plate 401 is fixed to the bottom of the side plate 301, and the connecting sleeve 402 is installed at the outer bottom end of the base plate 401. The steering assembly 4 also includes a base 403 and a second motor 404. The base 403 is rotatably connected inside the connecting sleeve 402, and the second motor 404 is installed inside the upper end of the base 403. The connecting sleeve 402 can be adjusted to the bottom. The base 403 and the base plate 401 are connected. The steering assembly 4 also includes a gear 405 and a gear ring 406. The output shaft of the second motor 404 is connected to the gear 405, and the gear ring 406 is meshed on one side of the gear 405. The gear ring 406 is fixedly connected to the base plate 401. The second motor 404 drives the base plate 401 to rotate through the gear 405 and the gear ring 406, changing the orientation of the directional microphone body 1, thereby enabling precise sound pickup at a specific angle and further expanding the range of use of the device.

[0022] like Figure 2 and Figure 3As shown, a limiting groove 5 is formed on the inner side of the support frame 2, and a protrusion 6 is slidably connected inside the limiting groove 5. The protrusion 6 is fixedly connected to the directional microphone body 1. The limiting groove 5 and the protrusion 6 are used to quickly limit the position between the support frame 2 and the directional microphone body 1.

The compression spring 704 will push the lever 703 under the limit of the fixing ear 701, causing the pin 702 to be inserted into the positioning hole 705, so as to quickly assemble the directional microphone body 1 and the bracket 2.

[0023] In summary, when using this adjustable pickup angle microphone, firstly, according to... Figure 1 , Figure 2 and Figure 3 The structure shown illustrates that during assembly, moving the toggle block 703 causes the pin 702 to avoid contact with the support frame 2. At this time, the limiting groove 5 and the protruding strip 6 quickly limit the movement between the support frame 2 and the directional microphone body 1. Upon release, the compression spring 704, limited by the fixing ear 701, pushes the toggle block 703, causing the pin 702 to insert into the positioning hole 705, quickly assembling the directional microphone body 1 and the support frame 2. Then, during use, when it is necessary to adjust the pickup angle of the directional microphone body 1, the first motor 303 can be activated via the controller, causing it to drive the worm gear 304 to rotate. This allows the worm gear 305 to drive the adjustment shaft 306 to rotate, adjusting the tilt angle of the directional microphone body 1. Then, the second motor 404 inside the base 403 can be activated as needed, causing it to drive the base plate 401 to rotate via the gear 405 and gear ring 406, thus changing the orientation of the directional microphone body 1. This enables precise sound pickup at specific angles, further expanding the range of applications of the device. Finally, when storing, simply moving the lever 703 will separate the pin 702 from the positioning hole 705, eliminating the need for other tools during disassembly and improving ease of use.
