A waterproof ring 10 is adhesively fixed at the connection between the upper housing 1 and the lower housing 2 with the waterproof glue being polyurethane glue. Advantages: Since polyurethane glue has excellent elasticity and anti-aging properties, it can adapt to the deformation of various substrates, effectively preventing leakage. It also has good adhesion, can be closely combined with various substrates to form a dense waterproof layer. In addition, polyurethane glue also has excellent anti-ultraviolet properties, and can maintain a lasting waterproof effect in areas with strong sunlight. Meanwhile, the waterproof ring 10 adhesively fixed at the connection between the upper housing 1 and the lower housing 2 with polyurethane glue can also prevent the corrosion of the connection by the sweat of the user over a long time and the damage to the interior caused by the entry, thus enabling the device to have a good waterproof effect.

[0026] Furthermore, a dust-proof membrane net 12 is fixedly installed in the inner cavity of the auricle part 11, and the outer wall of the dust-proof membrane net 12 is closely attached to the inner wall of the auricle part 11. Advantages: The dust-proof membrane net 12 can filter and block dust and impurities from the outside world. At the same time, setting the outer wall of the dust-proof membrane net 12 to be closely attached to the inner wall of the auricle part 11 can prevent the occurrence of gaps and the invasion of dust and cause damage. Meanwhile, a tissue can also be used to wipe and clean the dust and impurities blocked and filtered by the dust-proof membrane net 12, thereby being able to improve the service life of the device.

[0027] Furthermore, a Bluetooth headset includes the Bluetooth headset waterproof structure as described in any one of the above.

[0028] In the specific implementation of the present utility model, first, by aligning and inserting the two mounting blocks 9 in the second elliptical cover 7 inside the lower housing 2 into the corresponding mounting grooves 5, it is convenient to closely fit and connect the lower housing 2 and the upper housing 1. After the lower housing 2 and the upper housing 1 are connected, the sealing ring 6 and the waterproof film 8 can also be squeezed and fitted, tightly fitting and waterproofing the connection between the lower housing 2 and the upper housing 1, preventing water from entering and damaging the device. At the same time, the polyurethane glue at the connection between the lower housing 2 and the upper housing 1 has excellent elasticity and anti-aging properties, can adapt to the deformation of various substrates, effectively prevent leakage, and it also has good adhesion, can closely combine with various substrates to form a dense waterproof layer. In addition, the polyurethane glue also has excellent anti-ultraviolet performance, can maintain a lasting waterproof effect in areas with strong sunlight. At the same time, the waterproof ring 10 adhesively provided at the connection between the upper housing 1 and the lower housing 2 by the polyurethane glue can also prevent the sweat of the user from corroding the connection and entering the interior and causing damage over a long time, so that the device has a good waterproof effect. And through the dust-proof membrane net 12, dust and impurities from the outside can be filtered and blocked. At the same time, by closely fitting the outer wall of the dust-proof membrane net 12 with the inner wall of the auricle part 11, it can prevent gaps from occurring and dust from invading and causing damage. At the same time, a tissue can be used to wipe and clean the dust and impurities filtered and blocked by the dust-proof membrane net 12, thereby improving the service life of the device.
