Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

Example:

The embodiment of the utility model provides a multifunctional bluetooth headset, as shown in Figure 1, comprising: a housing, a main circuit board, a 3.5mm audio interface socket, a lithium battery and a micro charging interface, the main circuit board is installed in the housing, 3.5 The mm audio interface base and the micro charging interface are installed on the edge of the shell. The main circuit board is equipped with a Bluetooth main chip and a power amplifier that are electrically connected in turn. The lithium battery is installed in a battery holder on the main circuit board to supply power for the entire main circuit board. , the Bluetooth main chip decodes the received Bluetooth audio signal and outputs it to the power amplifier, the power amplifier is connected to the 3.5mm interface female socket, and the micro charging interface is electrically connected to the battery holder for charging the lithium battery. Bluetooth main chip adopts GPS Bluetooth chip.

The Bluetooth main chip decodes the Bluetooth audio signal and processes the audio signal to the power amplifier. After the power amplifier is amplified, it outputs to the 3.5mm audio interface female socket. The 3.5mm audio interface female socket can be connected to various external amplification devices, and can also be connected to earphones alone.

There is a spring clip on the back of the shell, which can make the bluetooth headset clipped on the collar or strap of the clothes, which is easy to carry. The back of the shell can also be integrally molded with a splint, forming a gap between the splint and the back of the shell, the root of the splint is fixed on the back of the shell, and the free end of the splint can be opened.
