DETAILED DESCRIPTION OF THE INVENTION

[0023] The present invention will be further described below in conjunction with the drawings and embodiments.

[0024] Please refer to the attached Figures 1-4 , a wireless earphone with a thin-walled and light-transmitting LED lamp in an embodiment of the present invention.

[0025] The wireless earphone with a thin-walled and light-transmitting LED lamp includes: a housing 10, and a control circuit board 30 and a lamp cover 20 disposed inside the housing 10. An LED lamp 32 is provided on the control circuit board 30, the LED lamp 32 is placed inside the lamp cover 20, the material of the lamp cover 20 is an elastic material, and the lamp cover 20 is squeezed between the control circuit board 30 and the inner side wall of the housing 10. A light guide hole 21 is formed in the lamp cover 20, and a light-transmitting groove 13 is formed in the inner side wall of the housing 10 at a position corresponding to the light guide hole 21, and the light-transmitting groove 13 and the outer side wall of the housing 10 form a thin wall 12 for light transmission.

[0026] The present invention utilizes the elastic lamp cover 20, which is squeezed between the control circuit board 30 and the inner side wall of the housing 10, so as to achieve sealing between the lamp cover 20 and the control circuit board 30, preventing the light of the LED lamp 32 from overflowing from the gap between the lamp cover 20 and the control circuit board 30 and affecting the effect of light positioning and transmission. And, a light guide hole 21 is formed in the lamp cover 20, the light guide hole 21 corresponds to the thin wall 12, and the light of the LED lamp 32 can be transmitted through the light guide hole 21 from the thin wall 12. The structure is simple, there is no need to punch holes in the housing 10, and there is no need to apply glue for installation and sealing. The present invention only needs to align the lamp cover 20 with the LED lamp 32, place the LED lamp 32 inside the lamp cover 20, and then use the control circuit board 30 and the housing 10 to clamp and fix the lamp cover 20 and achieve sealing. The installation is convenient, the cumbersome operation is reduced, the production efficiency can be improved, and the problem of glue overflow and light shielding affecting light transmission can be prevented without applying glue, and the problem of light transmission of existing colored earphones can also be solved.

[0027] Specifically, in this embodiment, the material of the lamp cover 20 is silicone or rubber or plastic with resilience.

[0028] The material of the housing 10 is a material that is easy to transmit light, such as ABS plastic, etc. In addition, the material of the housing 10 can also be a material that can transmit light when the thin wall 12 is thin to a certain extent, such as POM plastic, PBT plastic, etc.

[0029] In order to make the thin wall 12 light-transmitting, the thickness of the thin wall 12 is controlled within 0.2 - 0.6 mm, preventing the thin wall 12 from being easily punctured when the thickness is too thin, and also preventing the thick wall 12 from affecting the light-transmitting property. Optimally, the thickness of the thin wall 12 is 0.35 mm.

[0030] To facilitate the alignment and installation of the lamp cover 20, a limiting cavity 14 is provided inside the housing 10, and the lamp cover 20 is placed inside the limiting cavity 14 to achieve positioning. Therefore, in the present invention, the lamp cover 20 can be first placed inside the limiting cavity 14, and then the control circuit board 30 is locked inside the housing 10 by screws, and the lamp cover 20 is pressed between the housing 10 and the control circuit board 30, thereby achieving sealing.

[0031] In an embodiment, a sound guide cover 15 is formed inside the housing 10. A sound pickup component 33 is provided on the side of the control circuit board 30 away from the LED lamp 32. A through hole 31 communicating with the sound guide cover 15 is opened at the sound pickup port of the control circuit board 30 corresponding to the sound pickup component 33, and a sound guide hole 11 communicating with the sound guide cover 15 is opened on the housing 10. In this way, external sound can enter the sound pickup component 33 through the sound guide hole 11 and the through hole 31, thereby achieving sound pickup. Specifically, the sound pickup component 33 is a MIC component.

[0032] To make the structure of the Bluetooth headset of the present invention more compact, a surrounding wall 16 is provided inside the housing 10, and the limiting cavity 14 is composed of the housing 10, the surrounding wall 16 and the sound guide cover 15. Using the sound guide cover 15 to cooperate to form the limiting cavity 14 can reduce the volume of the Bluetooth headset.

[0033] The above are only the embodiments of the present invention. It should be noted here that for those of ordinary skill in the art, improvements can be made without departing from the creative concept of the present invention, but these all belong to the protection scope of the present invention.
