[0030] Figures 1 to 6 It is the accompanying drawing of the present invention.

[0031] This embodiment provides a wind noise-proof earphone device, see Figures 1 to 6 , comprising a housing 10, a first sound pickup hole 11 and a second sound pickup hole 12 arranged on the same side of the housing 10. The first sound pickup hole 11 and the second sound pickup hole 12 are connected through a channel 13, and the channel 13 is connected to a microphone 14. The first sound pickup hole 11 and the second sound pickup hole 12 are arranged along the axial direction of the device, and the channel 13 is arranged along the lateral direction of the device, so that the first sound pickup hole 11 and the second sound pickup hole 12 are connected to each other. The shell 10 is designed in an arc shape on one side of the first sound pickup hole 11 and the second sound pickup hole 12. The hole directions of the first sound pickup hole 11 and the second sound pickup hole 12 intersect with the arc-shaped shell 10, and there is a certain distance between the first sound pickup hole 11 and the second sound pickup hole 12, which can be understood as a symmetrical setting. In this way, when wind enters from the first sound pickup hole 11 and the second sound pickup hole 12, they intersect through the channel 13. Since the first sound pickup hole 11 and the second sound pickup hole 12 have sound interference at the channel 13, a resonance and sound elimination phenomenon is generated, so as to filter out the high-frequency sound in the wind noise.

[0032] Specifically, the first sound pickup hole 11 and the second sound pickup hole 12 are interconnected through the channel 13. When wind enters from the first sound pickup hole 11, it can flow into the second sound pickup hole 12 through the channel 13, and the wind entering the second sound pickup hole 12 can also flow into the first sound pickup hole 11 through the channel 13. In this way, the two interconnected first sound pickup holes 11 and the second sound pickup holes 12 can weaken the wind energy, thereby further reducing the wind energy entering the through hole 171. Furthermore, an acoustic mesh 15 is provided between the through hole 171 and the channel 13. The acoustic mesh 15 can further weaken or eliminate the wind energy. Finally, the wind energy reaching the microphone 14 is very small, so as to achieve the effect of eliminating wind noise.

[0033] Preferably, an acoustic mesh 15 is provided between the microphone 14 and the channel 13. The acoustic mesh 15 is made of damping material and can further reduce wind energy effectively.

[0034] The microphone 14 is fixed to a circuit board 16 provided therein, and the circuit board 16 is fixed in the housing 10 . The microphone 14 is fixed to the circuit board 16 in the form of a patch and is arranged close to the channel 13 .

[0035] The microphone 14 is wrapped with a silicone sleeve 17. The silicone sleeve 17 is connected to the channel 13 through a through hole 171. The acoustic mesh 15 is arranged between the through hole 171 and the channel 13. The silicone sleeve 17 is sealed and connected to the circuit board 16 so that the microphone 14 will not be disturbed by external sounds.

[0036] Specifically, the housing 10 is provided with a first mounting position and a second mounting position. The first mounting position is provided with a first mounting member 18, and the second mounting position is provided with a second mounting member 19. The first mounting member 18 is provided with a first hole to form a first sound pickup hole 11. The second mounting member 19 is provided with a second hole to form a second sound pickup hole 12.

[0037] A connecting member 20 is provided inside the housing 10. The connecting member 20 is arranged close to the first mounting member 18 and the second mounting member 19, so that the channel 13 is formed between the connecting member 20 and the first mounting member 18 and the second mounting member 19. Preferably, the connecting member 20 is a plastic member so that the first mounting member 18 and the second mounting member 19 can be isolated from each other to avoid short circuit.

[0038] The first mounting member 18 and the second mounting member 19 are metal members and are electrically connected to the circuit board 16 so that the first mounting member 18 and the second mounting member 19 serve as positive and negative electrodes to charge the device and exchange data, mainly for DC charging and AC signal communication.

[0039] The first mounting member 18 and the second mounting member 19 are both provided with an extension portion 181 , and the extension portion is electrically connected to the circuit board.

[0040] Preferably, the cross-sectional area of ​​the first sound pickup hole 11 and the second sound pickup hole 12 is greater than 0.6 mm 2 The first sound pickup hole 11 and the second sound pickup hole 12 may be circular, elliptical, racetrack-shaped, rectangular or other shapes.

[0041] Preferably, the volume of the channel 13 is less than 12 mm 3 .

[0042] Preferably, the acoustic mesh 15 is made of damping material.

[0043] Preferably, the channel 13 is a cavity structure.

[0044] The earphone device with wind noise protection and charging has better call effect, active noise reduction, and realizes the transmission of AC and DC signals with external devices.

[0045] Compared with the prior art, the first sound pickup hole 11 and the second sound pickup hole 12 of the present invention are interconnected through the channel 13 to guide and eliminate the wind noise energy and achieve the purpose of eliminating the wind noise. The structure is simple and the wind noise elimination effect is obvious. At the same time, the structure has the functions of DC charging and AC signal communication and has various functions.

[0046] The above examples are only used to further illustrate the technical content of the present invention, so that readers can understand it more easily, but they do not mean that the implementation of the present invention is limited to this. Any technical extension or re-creation made according to the present invention is protected by the present invention. The protection scope of the present invention shall be subject to the claims.
