There is a power amplifier loop inside the Bluetooth speaker, and the working heat is a normal phenomenon.
As long as the fever is not enough to interfere with work, it should not matter. In fact, any electronic device at work, will heat up, this is a normal phenomenon.
Generally, there is more heat with a power amplification loop, and less heat without a power amplification loop.
Loudspeaker hot is a normal phenomenon need to heat dissipation solution heating method:
< br >
1. Use appropriate volume not too much;
< br >
2. Pay attention to the temperature of the use environment, do not use it in a high temperature environment for a long time. Pay attention to the air circulation around the speaker, and properly reduce the temperature of the use environment.
The capacity of the battery is small, and the charging current is large, and it will heat up.
