Wireless blue-tooth earphone

A wireless blue-tooth earphone being chargeable by a charging case, the charging case being equipped with a plurality of conductive pieces, comprising:

• an earphone shell having an accommodating space penetrating through a lower portion of the earphone shell, one end of a peripheral surface of the earphone shell being recessed inward to form a recess;
• an earplug assembled to a bottom of the earphone shell;
• a speaker unit accommodated in a front end of the accommodating space;
• a circuit board assembly being accommodated in a rear end of the accommodating space and being connected with the speaker unit, a lower surface of the circuit board assembly being equipped with a plurality of elastic elements arranged next to the recess;
• and
• a contact assembly fastened in the recess, the contact assembly having a plurality of conducting elements arranged in the recess, the plurality of the conducting elements including a positive conduction part, a negative conduction part, and a conduction component located between the positive conduction part and the negative conduction part, the positive conduction part, the negative conduction part and the conduction component being fastened in the recess, the positive conduction part, the conduction component and the negative conduction part being juxtaposed from one side of the recess to the other side of the recess, the plurality of the elastic elements being electrically connected with the plurality of the conducting elements, the positive conduction part having a positive camber structure extended along an extending direction of the one side of the recess, and the negative conduction part having a negative camber structure extended along an extending direction of the other side of the recess, the conduction component having a circular camber structure, the positive camber structure being covered to an inner wall of the one side of the recess, the negative camber structure being covered to an inner wall of the other side of the recess, the circular camber structure being arranged in a middle of the recess and being located between the positive camber structure and the negative camber structure, the positive camber structure, the circular camber structure and the negative camber structure resisting against the plurality of the conductive pieces of the charging case.
