[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 4, a high-capacity parallel microphone that is resistant to radio frequency interference, comprising:

[0023] An elastic hoop 1 is fixedly connected to a placement box 2, a receiver 3 is placed in the placement box 2, the receiver 3 is electrically connected to a connecting line 4, and the end of the connecting line 4 away from the receiver 3 is electrically connected to a microphone head 5, wherein the receiver 3 and the microphone head 5 adopt anti-RF interference chips in the prior art, and the microphone head 5 adopts a large-capacity parallel microphone in the prior art.

[0024] The elastic hoop 1 adopts an elastic hoop body structure with an opening, which is convenient for use.

[0025] The top of the placement box 2 is long and open, which is convenient for taking and placing the receiver 3 and routing the connecting line 4.

[0026] The wire-winding mechanism includes a rotating rod 7, a clamping assembly and a winding drum 11. The rotating rod 7 is rotatably connected to one side of the placement box 2. The rotating rod 7 extends into the placement box 2 and one end is coaxially fixedly connected to the winding drum 11 and is connected to the clamping assembly. One end of the clamping assembly rests on the receiver 3, and the other end rests on the winding drum 11. The middle part of the connecting wire 4 is wound around the winding drum 11.

[0027] One end of the connecting line 4 close to the microphone head 5 is fixedly connected with a mounting clip 6, wherein the mounting clip 6 is clamped on an object near the sound-emitting position, wherein the mounting clip 6 adopts an existing spring clip.

[0028] One end of the rotating rod 7 away from the receiver 3 passes through the placement box 2 and is fixedly connected with a handle 13 .

[0029] The clamping assembly includes a rotating sleeve 8, a rotating ring 9 and a squeezing spring 10. The rotating sleeve 8 and the rotating ring 9 rotate coaxially and are slidably connected to the rotating rod 7. The squeezing spring 10 is fixedly connected between the rotating sleeve 8 and the rotating ring 9. The side of the rotating sleeve 8 away from the squeezing spring 10 abuts against the receiver 3, and the side of the rotating ring 9 away from the squeezing spring 10 abuts against the winding reel 11.

[0030] The rotating sleeve 8 and the rotating ring 9 are both fixedly connected with anti-skid pads 14 on opposite sides thereof. The anti-skid pads 14 are made of rubber.

[0031] A winding groove 12 is coaxially formed in the middle of the winding drum 11, wherein the middle of the connecting wire 4 is wound in the winding groove 12, and the winding drum 11 is elastic.

[0032] The operating principle of the utility model is now described as follows:

[0033] When in use, by turning the handle 13, the rotating rod 7 is rotated and adjusted, and the rotating rod 7 rotates to drive the winding drum 11 to rotate, thereby winding and releasing the connecting wire 4, so that the connecting wire 4 extending out of the placement box 2 is left with the required length;

[0034] After the length adjustment of the connecting wire 4 is completed, the rotating sleeve 8 is pressed against the receiver 3 under the elastic force of the squeezing spring 10, forming a squeezing and fixing effect on the receiver 3, preventing the receiver 3 from loosening and detaching from the placement box 2, and improving the stability of the receiver 3 during work; at the same time, the squeezing spring 10 makes the rotating ring 9 press against the winding drum 11, so that the winding drum 11 is deformed to form a squeezing and fixing effect on the connecting wire 4 in the winding groove 12, preventing the connecting wire 4 from loosening and affecting the normal use of the user;

[0035] Finally, the microphone head 5 is clamped on an object near the sound-generating position, such as the collar of the user, by means of the mounting clip 6, and the elastic hoop 1 is clamped around the neck of the user.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
