[0002] A compact microphone, also known as a portable microphone, is a lightweight, easy-to-carry recording device. Due to its compact size and weight, compact microphones have become the first choice for many recordists and podcasters.

[0003] In the existing small microphone, there is a microphone body, a sound collection hole is arranged on one side of the microphone body, the sound collection hole is used to collect external sound, and the whole device mainly collects sound through the sound collection hole, and a clamping body is arranged on the side of the microphone body close to the sound collection hole, the clamping body generally includes a first clamping plate and a second clamping plate, the first clamping plate and the second clamping plate are connected by a connecting rod, and a torsion spring is arranged on the outer wall of the connecting rod for providing force when clamping the first clamping plate and the second clamping plate, and the clamping body makes it possible to fix the microphone body to a collar or the like, but due to its own weight, the sound collection hole on the existing microphone body usually cannot be aligned with the mouth after being clamped with the collar. If the sound collection hole is not aligned with the mouth, the clarity and details of the sound may be affected, causing the sound to sound fuzzy or unclear, and when the sound collection hole deviates from the mouth by too large an angle, the sound may be distorted or deformed.

[0004] Therefore, it is necessary to provide a new small microphone to solve the above technical problems. Utility Model Content

[0013] Compared with the related art, the small microphone provided by the utility model has the following beneficial effects:

[0014] The device is provided with a pushing plate, an elastic member and a movable rod. By rotating the microphone body, the position of the sound collection hole on the microphone body is aligned with the mouth. The pushing plate is pushed by the clamping body. The movement of the pushing plate drives the movable rod to the inside of the limiting hole set on the microphone body. In this process, the movement of the movable rod drives the limiting plate to move, and the movement of the limiting plate achieves a compression effect on the elastic member. The movable rod enters the inside of the limiting hole to achieve a fixing effect between the clamping body and the microphone body. The clamping body is clamped on the collar. When the angle of the microphone body needs to be adjusted again, the microphone body can be rotated again by loosening the clamping body. The device can make the sound collection hole on the microphone body align with the mouth, and reduce the probability of sound distortion, thereby improving the accuracy of the sound recorded by the microphone.

[0025] The limiting device includes a fixed block 11, a pushing plate 13, a movable rod 14 and a limiting plate 15, one end of the movable rod 14 movably passes through the fixed block 11, one end of the movable rod 14 close to the fixed block 11 movably extends to the inside of the limiting hole 5, one end of the movable rod 14 away from the limiting hole 5 is fixedly passed through the limiting plate 15, the outer wall of the limiting plate 15 is movably connected to the inner wall of the fixed block 11, one side of the limiting plate 15 is fixedly connected with an elastic member, one end of the elastic member away from the limiting plate 15 is fixedly connected to the inner wall of the fixed block 11, one end of the movable rod 14 away from the limiting plate 15 is fixedly connected to one side of the pushing plate 13, one end of the pushing plate 13 away from the movable rod 14 is movably connected to one side of the clamping body, the elastic member is a spring 10, one end of the spring 10 is fixedly connected to one side of the limiting plate 15, and one end of the spring 10 away from the limiting plate 15 is fixedly connected to the inner wall of the fixed block 11;

[0026] The clamping body includes a first clamping plate 7, a second clamping plate 8 and a connecting rod 12. The first clamping plate 7 and the second clamping plate 8 are connected by the connecting rod 12. The outer wall of the connecting rod 12 is provided with a torsion spring 9. The opposite ends of the torsion spring 9 are movably connected to the adjacent sides of the first clamping plate 7 and the second clamping plate 8 respectively.

[0029] When the device is in use, the first clamping plate 7 and the second clamping plate 8 need to be separated first. At this time, since the movable rod 14 loses its driving force, the movable rod 14 leaves the limiting hole 5 under the action of the limiting plate 15 and the spring 10. At this time, the microphone body 1 can be rotated. After being rotated to a suitable position, the collar is placed between the first clamping plate 7 and the second clamping plate 8. By loosening the first clamping plate 7 and the second clamping plate 8, the first clamping plate 7 and the second clamping plate 8 are moved in adjacent directions by the action of the torsion spring 9, so that the movable rod 14 is pushed back to the inside of the limiting hole 5, thereby fixing the position of the microphone body 1.
