Rotary audio plug assembly and electronic device with rotary audio plug

Abstract

The invention discloses a rotary audio plug assembly and an electronic device with a rotary audio plug. The rotary audio plug assembly comprises the audio plug, a pivotal shaft and a plurality of electric connecting lines, wherein the audio plug is provided with a plurality of pins, the pins include the microphone pin, the ground wire pin and at least one sound track pin, a first contact element is arranged at the end of the audio plug, the first contact element is electrically connected with one of the pins, one end of the pivotal shaft is arranged on the first contact element so that a storage space can be limited between the pivotal shaft and the first contact element, all the electric connecting lines are stored in the storage space and wound around the pivotal shaft, and the electric connecting lines are electrically connected with the pins one to one. According to the rotary audio plug assembly, the electric connecting lines are small in the range of motion, the space needed for rotation of traditional leads is omitted, the size of the electronic device is reduced, the phenomenon that electric connecting lines are broken due to motion can be avoided, and reliability of the function of the audio plug is ensured.

Description

technical field [0001] The invention relates to the field of electronic products, in particular to a rotary audio plug assembly and electronic equipment with the rotary audio plug. Background technique [0002] Such as Figure 9 As shown, the connection between the audio plug 2' and the PCB board 1' in the existing earphones is realized by welding the lead wire 7' on the PCB board 1'. During the rotation of the audio plug 2', there will be Drive the movement of the lead wire 7', and the lead wire 7' is always in the bending movement, which will cause the lead wire 7' to break and cause damage to the function, and in order to ensure the movement of the lead wire 7', it is necessary to reserve a large space 8', causing the product The size is larger. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] Therefore, an object of the present invention is to provide a rotar...
