Abstract: Disclosed are a method, system and controller for simultaneously verifying amplitude and temperature parameters of an electrical-acoustic conversion device, including: inputting a sweep signal to the electrical-acoustic conversion device; testing the amplitude of the electrical-acoustic conversion device while adjusting the gain of the whole frequency band of the sweep signal until the maximum value of the tested amplitude is a maximum amplitude parameter Xmax, and testing the temperature of a voice coil at this moment; and if the tested temperature of the voice coil at this moment is higher or lower than Tmax, gradually reducing/increasing the gain of the sweep signal in the frequency band above a gain improvement frequency point until the tested temperature of the voice coil is Tmax, and then maintaining the gain of the sweep signal for a predetermined period of time and then testing the performance of the electrical-acoustic conversion device.
