Abstract

A coaxial speaker tweeter temperature protection method, a coaxial speaker tweeter temperature protection system, and a computer-readable storage medium are provided. The coaxial speaker tweeter temperature protection method is applied to a coaxial speaker including a tweeter and a woofer, including steps of acquiring a woofer real-time temperature, performing calculation on the woofer real-time temperature and a pre-processed input signal through a tweeter temperature prediction algorithm to predict a tweeter real-time temperature in a current state, where the pre-processed input signal is a signal acquired after processing a sound effect algorithm on an input audio signal, etc. Compared with the related art, the coaxial speaker tweeter temperature protection method, the coaxial speaker tweeter temperature protection system, the electronic device, and the computer-readable storage medium provide better temperature protection for the tweeter, reliability of which is better.
