A kind of tws earphone system, tws earphone and earphone charging box

Abstract

The invention discloses a TWS earphone system, which includes an earphone body with an elastic lock tongue and a positioning groove used to limit the position of the earphone body. The positioning groove is fixed with a lock component and an elastic pad; when the elastic lock tongue is pressed down to the first position , the elastic lock tongue is locked with the buckle assembly and the earphone body is in contact with the elastic pad, and the earphone body is positioned; when the elastic lock tongue is pressed down to the second position, the elastic pad restores elastic deformation to assist the elastic lock tongue to move up until Disengage from the lock assembly, and the earphone body is released. The locking force generated when the elastic lock tongue is locked with the buckle assembly and the elastic force applied to the earphone body by the elastic pad jointly define the position of the earphone body, avoiding the use of buckle force to limit the earphone body in one direction, avoiding the laying of magnets, reliable positioning and occupying space Therefore, the TWS earphone system provided by the present invention can improve structural compactness and positioning reliability. The invention also discloses a TWS earphone and an earphone charging box.

Description

technical field [0001] The invention relates to the technical field of earphones, in particular to a TWS earphone system. The invention also relates to a TWS earphone and an earphone charging box. Background technique [0002] TWS earphones, that is, true wireless stereo earphones, use Bluetooth connections instead of physical wires, which are more convenient to use and are favored by consumers. [0003] Existing TWS earphones are usually equipped with a charging box with both charging and storage functions. The TWS earphone has a charging contact pin, and the charging box has a power supply contact pin that offsets the charging contact pin. Given that the contact area between the charging contact pin and the power supply pin is usually Smaller, in order to achieve stable charging, it is usually necessary to fix the TWS earphones in the charging box. However, there are still some defects in the fixing method of the existing TWS earphones: [0004] The charging box usually ...

AI Technical Summary

Problems solved by technology

[0004] The charging box usually includes an upper shell and a lower shell that are pivotally connected to each other. There is a positioning slot between the upper shell and the lower shell to limit the position of the TWS earphone. Considering that consumers can easily take the TWS earphone, the shape of the positioning slot is The cavity size is usually slightly larger than the overall size of the TWS earphone, so that the positioning groove cannot reliably define the position of the TWS earphone. Although the TWS earphone can still be re-defined by extrusion during the fastening process of the upper shell, the extrusion force can only TWS earphones are limited in one direction, and there is still a risk of shaking for TWS earphones, and the positioning reliability is relatively poor;

[0005] Furthermore, magnets with different polarities are set between the positioning groove of the charging box and the TWS earphones, which facilitates the positioning of the TWS earphones by magnetic attraction. In order to achieve reliable positioning, it is usually necessary to distribute a large area of ​​magnets. The large size makes the structure of the charging box not compact, and the magnets distributed in a large area may still cause the risk of misalignment of the TWS earphones, affecting the reliability of positioning
