1. A speaker temperature protection method, applied to a device comprising a power amplifier and a combination device comprising a speaker and a motor, comprising:
creating a target transfer function based on a first real-time temperature of the speaker and a first real-time fusion voltage relative to the combination device;
obtaining a first predicted temperature of the speaker based on the target transfer function, and determining a target gain according to the first predicted temperature of the speaker and a first fusion power relative to the combination device; and
performing gain processing on an original audio signal input to the combination device based on the target gain, so as to provide temperature protection for the speaker.
