The invention discloses a method and system for verifying amplitude and temperature parameters of an electroacoustic converter simultaneously. The method comprises that frequency swept signal is input to the electroacoustic converter; the full-band gain of the frequency swept signal is adjusted till the tested amplitude maximum equals the maximal amplitude parameter Xmax, and the temperature of a coil at the moment is tested; and if the tested temperature of the coil is higher/lower than Tmax, the gain of the frequency swept signal in the frequency band over the gain improving frequency point is gradually decreased/increased till the tested coil temperature equals Tmax, the performance of the electroacoustic converter is tested after operation for a preset time and in the unchanged gain of the frequency swept signal, and the frequency of the gain improving frequency point is greater than the resonant frequency F0 of the electroacoustic converter. The method enables that the coil temperature reaches Tmax when the electroacoustic converter reaches the maximal amplitude Xmax, the limit vibration state of the electroacoustic converter is simulated more accurately, and a text result is more accurate and more reliable.
