Abstract
A method and system for testing a temperature tolerance limit of a loudspeaker. The method includes: selecting a test signal, and determining a test output voltage as a rated voltage of the loudspeaker, so that the loudspeaker reaches a rated amplitude; determining a gain boosting frequency point according to a resonant frequency of the loudspeaker; performing a plurality of tests for the loudspeaker, and in each test controlling the test signal to maintain the gain constant in a frequency band lower than the gain boosting frequency point and increase the gain in a frequency band higher than the gain boosting frequency point, testing and recording a temperature of the loudspeaker till the loudspeaker fails, and recording a temperature at the time of the failure; and determining a highest temperature that is tolerable by the loudspeaker before the loudspeaker fails.
