Abstract

The invention discloses a microphone device capable of conducting adapterization from long distance, which comprises two microphones and a casing, wherein the two microphones are connected in parallel and then are placed into the casing; a front voice inlet hole is arranged in front of the casing, and a rear voice inlet hole is arranged in the side surface of the casing. Compared with the existing devices capable of conducting adapterization from long distance, in the invention, the high directionality of the microphone is realized, simultaneously, the physical dimension is greatly reduced, and no signal processing and algorithms are needed in the realization process, therefore, the record device is simple in structure, small and exquisite in dimension, low in cost and easy to realize.

Description

technical field

[0001] The invention relates to the technical field of sound pickup devices, in particular to a microphone device for long-distance sound pickup. Background technique

[0002] With the pilot promotion of triple play nationwide, the integration of computer network, telecommunication network and cable TV network has become a trend and has preliminary development and application. If you want to integrate the computer network and the telecommunications network on the TV, you need the TV to have the function of long-distance recording, that is, you can easily communicate with the other party at the position of watching TV.

[0003] For ordinary recording devices, while the microphone records the target voice signal, it will also record the environmental noise signal. Due to the long recording distance, the signal-to-noise ratio of the microphone recording will be insufficient, thus making the recorded sound blurred. Intelligibility is poor. Therefore, it is nece...
