[0002] The speaker is the terminal of the entire audio system. Its function is to convert audio electrical energy into corresponding sound energy and radiate it into space. The speaker is mainly composed of speakers (speaker units), cabinets, crossovers, sound-absorbing materials and other components. Bluetooth speakers can be connected to devices through Bluetooth modules for wireless control of the speakers.

[0003] Speakers produce sound through vibration. When working, the internal electronic components will generate a certain amount of heat. The accumulated heat inside the speaker will produce a higher temperature. Excessive temperature will easily accelerate the aging of the internal components of the speaker, which is not conducive to the long-term use of the speaker. Utility Model Content
