Self detection and correction method for electroacoustic system

Abstract

The invention provides a self detection adjustment method for electro acoustic system fit to any situation. Wherein, a self detection module build-in IC or DSP sends testing signal to be treated by a circuit element and transmitted by a audio sending device; at least one audio receiver takes over and sends the signal to connected circuit element for conversion into digital signal, then send back to self detection module for comparing the correlativity between send testing signal and back digital signal and optimizing the circuit parameter; then comes the next detection and adjustment for next parameter; if can not adjust, it sends testing failure alarm.

Description

technical field [0001] The invention relates to a self-testing and correcting method of an electro-acoustic system, in particular to a method for self-testing and automatically adjusting the electro-acoustic system in any occasion. Background technique [0002] With the development and popularization of science and technology, communication equipment such as telephones have become necessary for every household. Due to their low price, most of them will be replaced directly if there is a fault. However, if high-priced products such as conference phones have poor reception or Noise and other problems, not only the maintenance cost is expensive, but the maintenance equipment also costs more than 10,000 yuan. Whether it is sent for repair or repaired by itself, the cost is not small, which makes the user feel that it is too much. [0003] In the prior art, the internal circuits of these communication devices must be tested when they are semi-finished products, that is, before as...
