Remote pickup microphone

This creation is about a field of microphone technology, especially a long-distance pickup microphone.

According to the pilot promotion of triple play in the whole country, the integration of computer network, telecommunication network and cable TV network has become a trend and has initial development and application. If you want to integrate the computer network and the telecommunication network on the TV, you need the TV to have the function of long-distance recording, that is, you can easily communicate with each other while watching TV.

For an ordinary recording device, when the microphone records the target voice signal, the ambient noise signal is also recorded. Because the recording distance is long, the signal-to-noise ratio of the microphone recording is insufficient, so that the recorded sound is blurred. Incomprehensible. Therefore, it is required that the recording device can "pick" the signal, pick up the target signal, and suppress the environmental noise signal. The principle of long-distance pickup is: using the high directivity of the recording device, pointing to the target sound signal, and the sound signal reaching the recording device in other directions will be suppressed, thereby increasing the signal-to-noise ratio to achieve long-distance recording, that is, long-distance recording. It is achieved through the high directivity of the microphone.

Although the microphone on the market has realized the long-distance pickup effect to a certain extent, in the actual use process, due to many aspects, it will still find that it still fails to achieve the best use effect and work efficiency, and it picks up The sound effect is still not very good, and the sound discrimination is low.

Therefore, in view of the lack of prior art, the main purpose of the present invention is to provide a long-distance pickup microphone, in order to provide a microphone with high sound discrimination and long-distance pickup effect, thereby enabling the user to use during use. Pick up at a long distance to improve the sound discrimination.

The two circuit boards are disposed in the metal casing.

Further, the metal casing has a hollow cylindrical shape, and one end side wall extends inward to form a step, and the first circuit board abuts against the step.

Further, the first circuit board is circular.

Further, the second circuit board is square.

Further, one end of the second circuit board is provided with two first basic legs, and the first basic leg is electrically connected to the first circuit board.

Further, the single head is cylindrical.

The metal casing 10 has a hollow cylindrical shape, and an opening is formed at each end of the metal casing 10. The sidewall of one end of the metal casing 10 extends inward to form a step 11; in this embodiment, the metal The outer casing 10 is a copper outer casing. The first circuit board 20 is mounted in an opening of one end of the metal casing 10 and abuts against the step 11. The first circuit board 20 is circular. The second circuit board 30 is mounted in the metal casing 10, and the second circuit board 30 is square. Two first base legs 301 are disposed on one end of the second circuit board 30, and the two first base legs 301 are electrically connected to the first circuit board 20. The unitary head 40 is mounted in the other end opening of the metal casing 10. The unitary head 40 has a cylindrical shape. The inner end surface of the unitary head 40 is provided with a plurality of second base legs 401, and the second base leg 401. It is electrically connected to the foregoing second circuit board 30.

The assembly process of the remote range pickup microphone of the present invention is as follows: First, the first circuit board 20 is connected to the first base leg 301 of the second circuit board 30, and then the second unit of the single tone head 40 is The base pin 401 is connected to the second circuit board 30, and then the component that combines the first circuit board 20, the second circuit board 30 and the single sound head 40 is placed in the metal casing 10, so that the The first circuit board 20 is abutted against the step 11 of the metal casing 10. The single head 40 is fixedly coupled to the other end of the metal casing 10 to complete the assembly.

Referring to the fourth to sixth figures, the specific structure of the second preferred embodiment of the present invention is substantially the same as the specific structure of the first preferred embodiment, and the difference is A plurality of through holes 101 are defined in the side wall of the metal casing 10A.
