Embodiment Construction
[0025] The present invention provides a method for self-detection and correction of an electro-acoustic system, wherein the electro-acoustic system can be divided into figure 1 A one-to-one system of one speaker to one microphone shown, and figure 2 A one-to-many system of one loudspeaker to plural microphones is shown. In a one-to-one system, the detectable parameter items of the self-test module 10 include gain (Gain), sensitivity (Sensmvity), phase delay (Phasedelay) and frequency response (Frequency response); in a one-to-many system, the The parameter items detectable by the self-inspection module 10 include gain difference (Gain difference), sensitivity difference (Sensitivity difference), phase delay difference (Phase delay difference) and frequency response difference (Frequency response difference); the detection of gain parameters can maintain Program the linear relationship between the gain amplifier and the circuit, and make sure that its parameter values are w...
