Description

Spring needle assembly, earphone charging box and audio device Technical Field The application relates to the technical field of electronic equipment, in particular to a spring needle assembly, an earphone charging box and an audio device. Background The spring needle on the earphone charging box is used as a charging contact point for the charging box to be electrically connected with the earphone, and when the earphone is placed in the charging box, the spring needle is contacted with the earphone to provide current required by charging for the earphone. In the related art, the spring pin may be jammed, so that when the earphone is put into the charging box, the charging box cannot charge the earphone. Disclosure of utility model The present application aims to solve at least one of the technical problems existing in the prior art. Therefore, the application provides the spring needle assembly, the earphone charging box and the audio device, which can reduce the condition that the spring needle is blocked, so that the charging box can charge the earphone more stably. An embodiment of a latch needle assembly according to the first aspect of the present application includes: The head of the needle is used for being electrically connected with the earphone, and a containing cavity penetrating through the back of the needle is formed in the needle; The guide piece is partially penetrated in the accommodating cavity and is used for being electrically connected with the circuit board, and the needle head is movably arranged on the guide piece; the elastic piece is arranged in the accommodating cavity, one end of the elastic piece is abutted to the needle head, and the other end of the elastic piece is abutted to the guide piece.
