Abstract: A thermal protecting device of a speaker is provided. The thermal protecting device includes an amplifier and a temperature detecting unit. An input end of the amplifier receives an audio reference signal, an output end of the amplifier provides an audio output signal to the speaker. The temperature detecting unit receives an audio input signal to provide the audio reference signal, and detects an operation temperature of the speaker to determine an amplitude of the audio reference signal. The amplitude is inversely proportional to the operation temperature.

Abstract: A speaker includes a sound box, a speaker module, and a heat pipe. The sound box includes a first opening and a second opening. The speaker module is hermetically connected to the first opening. The heat pipe is hermetically connected to the second opening. The heat pipe includes a first end and a second end. The first end is located in the sound box. The second end is exposed to the second opening. The speaker module is fixedly connected to at least part of an outer wall of the heat pipe. In the speaker, a hollow heat pipe is fixedly connected to the speaker module, and vibration of the speaker module drives air in the heat pipe to flow to dissipate heat from the heat pipe. Further, the cold heat pipe carries heat away from the speaker module through heat transfer, thereby dissipating heat from the speaker.
