HEADPHONE CONNECTOR, HEADPHONE PLUG, HEADPHONE AND ELECTRONIC DEVICE

摘要

FIELD: physics.;SUBSTANCE: headphone connector comprises a connector body, in which the headphone jack is formed, and a plurality of the ground terminals, which are located in the headphone jack and contact the section located on the headphone plug, when the headphone plug is inserted into the headphone jack. Herewith the plurality of the ground terminals are located uniformly along the circumferential direction of the headphone jack, and each of the ground terminals comprises a common ground structure on the inner headphone jack wall, a head section, which contacts with the headphone plug, when the headphone plug is inserted into the headphone jack, and a resilient mechanism is inserted between the common ground structure and the head section. Furthermore, the head section of each of the ground terminals is a spherical metal structure, and the common ground structure is an annular metal structure located on the inner headphone jack wall.;EFFECT: reducing the headphone crosstalk coming from the main device board such as a smart terminal, by increasing the contact area of the ground terminals between the headphone plug and the headphone connector, that reduces the contact resistance between the headphone plug and the headphone connector.;7 cl, 10 dwg
