[0031] As a technical optimization of this utility model, by setting up the water channel 17, when it rains during outdoor wear, the water on the surface of the headphone frame 1 can be quickly drained through the water channel 17, improving the waterproof effect. By setting up the elastic memory metal column 18, the strength and service life of the headphone frame 1 are improved. By setting up the silicone skin-friendly layer, the comfort of the user when wearing it is improved.

[0032] The working principle and usage process of this utility model are as follows: By placing the speaker body 6 inside the middle shell 3 and the outer shell 4, the middle shell 3 and the outer shell 4 completely surround and protect the speaker body 6, reducing the contact between the speaker body 6 and water. At the same time, by setting a sealing gasket 5, the gaps at the connection are sealed to further improve the waterproof effect. By setting a hydrophobic groove 8, rainwater dripping onto the outer shell 4 can be quickly drained out to prevent rainwater from adhering. By setting a sound insulation layer 9, which is made of polyester fiber sound-absorbing material, it has excellent sound absorption performance and can absorb noise from the surrounding environment and internal noise, improving the overall sound quality of the headphones. By setting a waterproof sound-permeable component 10, the sound emitted by the speaker body 6 is filtered to improve the sound quality, while the inner side of the speaker body 6 is protected to prevent sweat and rainwater from entering the middle shell 3 from the inside and contacting the speaker body 6. This achieves the advantages of improving the waterproof effect of the headphones, preventing water damage to the headphones when using them outdoors or in daily life, improving the sound quality of the headphones, and making them more convenient for users.
