Description

Technical Field

[0001] The utility model relates to the technical field of waterproof structures, in particular to an earphone waterproof structure. Background Art

[0002] Headphones are an audio output device that converts audio signals into sound and transmits it to the user's ears. Headphones are usually composed of speakers, drivers, microphones, wires, etc., and can be connected to various audio devices such as mobile phones, computers, tablets, etc. through plugs. The waterproof structure design on the headphones is to ensure that the headphones can work normally in humid or underwater environments, while protecting the internal circuits from moisture damage.

[0003] Most common methods for waterproof structures on earphones use rubber gaskets or O-rings to fit the interfaces and connecting parts tightly to the shell to prevent moisture penetration. However, this method does not provide a waterproof component at the speaker hole of the earphone, which makes it easy for moisture to enter the interior of the earphone from the speaker hole and cause damage to the internal circuit board. Furthermore, we disclose an earphone waterproof structure to meet the actual demand for traditional earphone waterproof structures that do not provide a waterproof component at the speaker hole, which makes it easy for moisture to enter the interior of the earphone from the speaker hole and cause damage to the circuit board. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide an earphone waterproof structure to solve the problem that the traditional earphone waterproof structure does not have a waterproof component at the speaker hole, which makes it easy for moisture to enter the earphone from the speaker hole and cause damage to the circuit board.

[0005] Based on the above purpose, the utility model provides an earphone waterproof structure, including an earphone shell, one end of the earphone shell is clamped with an earphone cover, a waterproof component is arranged inside the earphone cover, the waterproof component includes a waterproof sound-transmitting plate threadedly connected to the inside of the earphone shell, the lower end of the earphone shell is fixedly connected with a drain valve, and a one-way valve assembly is arranged inside the drain valve.

[0006] Preferably, a waterproof layer is provided on one end surface of the waterproof sound-permeable board, and the waterproof layer is made of polyurethane material.

[0007] Preferably, the waterproof sound-permeable board is filled with a sound-absorbing layer, and the sound-absorbing layer is made of mineral wool material.

[0008] Preferably, a plurality of sound-permeable holes are evenly spaced apart on an end surface of the waterproof and sound-permeable board that is away from the waterproof layer.

[0009] Preferably, buckle grooves are provided at the upper and lower ends of the outer side of one end surface of the waterproof sound-permeable plate.

[0010] Preferably, the one-way valve assembly comprises a piston slidably connected inside the drain valve, and a sealing gasket is provided on the upper end surface of the piston.

[0011] Preferably, notches are provided on the outer sides of the upper ends of the pistons, and through holes are provided at the plurality of notches.

[0012] Preferably, a connecting hole is provided inside the piston, and the connecting hole is communicated with the plurality of through holes.

[0013] Preferably, a telescopic spring is fixedly connected to the upper end of the inner wall of the internal connecting hole of the piston, and the lower end of the telescopic spring is fixedly connected to the drain valve.

[0014] Preferably, a handle is fixedly connected to one side of the middle portion of the lower end of the earphone shell, and a speaker assembly is arranged inside the earphone shell and the earphone cover.

[0015] Beneficial effects of the utility model:

[0016] 1. The waterproof structure of the earphone is provided with a waterproof component at the speaker hole of the earphone. The waterproof layer on the sound board prevents moisture from entering the earphone from the speaker hole and causing damage to the earphone circuit board. The sound-absorbing layer can absorb and reduce the reflection and echo of the sound, thereby improving the sound transmission effect and the sound quality of the earphone.

[0017] 2. The waterproof structure of the earphone prevents external liquid from entering the earphone through the one-way valve assembly, and can quickly drain the liquid when it is contained in the earphone. When the earphone contains liquid, the weight of the liquid causes the telescopic spring to move downward, and the piston slides downward accordingly. The liquid is discharged from the drain valve through the through hole on the piston. After discharge, the piston moves upward again due to the action of the telescopic spring, and the sealing gasket fits against the inner wall of the drain valve, so external liquid is not easy to enter, which greatly improves the practical performance of the earphone.
