Abstract
A coaxial speaker protection method, a coaxial speaker protection system, a coaxial speaker protection device, and a coaxial speaker protector are provided. The coaxial speaker protection method includes modeling a temperature of a tweeter to obtain a tweeter voltage-temperature transfer function, modeling a temperature and an amplitude of a woofer to obtain a woofer voltage-amplitude-temperature transfer function, modeling a coaxial device having the tweeter and the woofer to obtain a thermal conduction function of the coaxial device, predicting a temperature at a next moment of the tweeter according to temperature information fed back by a current at a previous moment of the tweeter, etc. The tweeter and the woofer are protected through a feedforward manner, so that sound quality of a coaxial speaker is improved.
