[0002] Wireless headphones have the wire in the middle replaced by radio waves. They are connected from the audio port of the computer to the transmitter, which then sends the radio waves to the headphones at the receiving end. The receiving end is equivalent to a radio. There are three known types of wireless headphones. One is Bluetooth headphones, the second is infrared headphones, and the third is 2.4G.
[0003] Existing Bluetooth headsets only have a single heat dissipation hole for mainboard heat dissipation, so that the headset mainboard is in contact with the outside air to achieve heat exchange. Since there is no device at the heat dissipation hole to promote air circulation, the heat emitted by the mainboard cannot be quickly dissipated. Over a long period of time, the mainboard temperature will be too high and the components on the mainboard will be damaged to varying degrees.
[0004] In the prior art, the Bluetooth headset mainboard is fixed inside the headset, receives signals for the Bluetooth headset, and transmits the signals to the speaker to achieve sound propagation. However, the mainboard is located inside the headset and is not well protected. Although the outer shell is closely connected, there is still a gap. Once an accident occurs, the headset as a whole falls into the water, and the mainboard is damaged after contacting the water, resulting in damage to the entire headset. Utility Model Content

[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1.

The upper shell is aligned with the top of the lower shell so that the circular plate can be perfectly inserted into the circular grooves opened at both ends of the upper shell, so that the card plate inside the upper shell corresponds to the card plate position inside the lower shell, so that the upper shell and the lower shell are perfectly combined. After the lower shell and the upper shell are fitted, no matter encountering sandstorm weather or falling into water, due to the relative sealing between the circular groove and the circular plate, and the relative sealing between the arc groove and the arc bar, external sand or water cannot enter the interior of the device, which has the effect of safety protection of the motherboard.
[0013] 2. The wireless headset motherboard integrated device realizes rapid cooling of the motherboard by arranging micro-fans, air vents and other structures. When the motherboard is working, heat is generated. A heat sink is installed at the bottom of the motherboard. The heat is concentrated on the heat sink and dissipated. The air outlet pipe is located below the heat sink. When the heat is dissipated from the heat sink, the micro-fan is started to generate suction at one end of the air intake pipe to absorb the dissipated heat into the interior of the micro-fan. Then the micro-fan dissipates the internal heat through the air outlet pipe. The hot air is blown into the heat pipe through the hole block. After the hot air dissipates the heat through the capillary, it returns to the air intake pipe from the heat pipe to achieve cooling, which has the effect of rapid cooling.
