It may be caused by the leakage of the button or the circuit board, or by the adhesion of the switch button. You can check whether there is water in the switch. If it is ruled out that there is something wrong with the control panel.

The extended data Bluetooth speaker has its unique features: 1, which is widely used. The specifications of Bluetooth technology are unified all over the world. As long as there are Bluetooth adapters, many devices such as mobile phones, PDA's, wireless headsets, notebook computers, automobiles, medical equipment and computer peripherals can be easily connected to Bluetooth devices for data transmission or voice communication, which is widely used and has good compatibility.

2. Easy-to-operate Bluetooth technology is an instant technology, which does not need fixed infrastructure, and its installation and setting are simple, and it can be connected without cables. It is very convenient to use, and it can be put into use only by matching, and the operating threshold is low.

3. The transmission speed is faster. Compared with other modes such as infrared, Bluetooth transmission protocol has obvious advantages in speed. The theoretical maximum speed of Bluetooth 4.0 reaches Mbps, and faster speed can ensure higher sound quality, so that it has enough capacity to carry music with higher bit rate.

4. The transmission distance is moderate. The transmission distance of Bluetooth is generally within meters, which is just the size of a room, and it can transmit data through a partition wall, which is very suitable for home environment.
