Multifunctional sound system with microphone code display and verification

Abstract

The present invention discloses a multi-function sound system with a function of displaying and verifying a microphone code. The multi-function sound system comprises a microphone and an audio mixer. The microphone is internally provided with a super audio signal generation circuit, a microphone code generation circuit, a microphone code serial output circuit, a microphone code display circuit, a first modulation circuit, an electroacoustic converter, a pickup device, a pickup processing circuit, a comparison detection circuit, a second demodulation circuit, a wireless receiving circuit, a microphone channel conduction state display circuit, a microphone code read serial output circuit, a second modulation circuit and a wireless transmit circuit. The audio mixer is provided with a signal allocation circuit, a filter amplification circuit, a first demodulation circuit, a filter circuit, an audio signal processing circuit and a microphone code read display circuit that are connected with a microphone input interface. The sound system disclosed in the present invention can display the microphone channel conduction state continuously in real time, so that both a tuner and a user of the microphone can see the microphone channel conduction state conveniently, so as to discover and eliminate the fault.

Description

technical field [0001] The invention relates to the technical field of audio equipment, in particular to a multifunctional audio system with microphone code display and verification. Background technique [0002] Audio system equipment is the most widely used media equipment, especially in education, business, entertainment, exhibition and other industries. [0003] The audio system mainly includes microphones, mixers, power amplifiers and speakers, etc. There is often a problem with the audio system currently in use: the person using the microphone starts to speak, but finds that the microphone cannot produce sound, which affects the quality of the performance, delays time, and appears This situation is what the tuner is most worried about, but this kind of performance accident is hard to avoid, no matter how much preparation is done in advance, this kind of situation will still happen. [0004] The common reasons for the microphone not making sound are: the person using t...

Problems solved by technology

[0003] The audio system mainly includes microphones, mixers, power amplifiers and speakers, etc. There is often a problem with the audio system currently in use: the person using the microphone starts to speak, but finds that the microphone cannot produce sound, which affects the quality of the performance, delays time, and appears This kind of situation is what the tuner is most worried about, but this kind of performance accident is hard to avoid, no matter how much preparation is done in advance, this kind of situation will still happen

Although the tuner can do sufficient debugging work before the start, it is difficult to avoid failures due to the large number of people in an event, time constraints, and many people are not familiar with the use of microphones.

[0005] When the tuner is testing the microphone, he usually inputs a sound signal at the microphone end, and then listens to see if there is any sound output from the speaker, but it is impossible to test like this after the program starts, and the tuner cannot detect the microphone leading to the mixer Therefore, if there is a problem with the microphone after the program starts, and it cannot be found in time, there will be a situation where the microphone does not make sound, which will affect the normal progress of the sound reinforcement, waste time, affect the effect, and sometimes cause irreparable Loss
