Abstract

The invention discloses an earphone socket and a realization method thereof. Because a first GND (Ground) pin, an MIC (Microphone) pin, a right sound channel pin and a first left sound channel are arranged at one side of a U port matched with the earphone socket from outside to inside in sequence, the first GND pin is connected with a reference ground and a second GND pin which is symmetrical to the first GND pin is arranged at the other side of the U port, the ESD (Electronic Static Discharge) protection of the earphone socket can be improved. The second GND pin is connected to an interrupt pin of a mobilephone baseband chip, wherein the interrupt pin is used for detecting inserted and pulled-out interrupt of an earphone, and the POP noise caused by inserting in and pulling out the earphone can be overcome by the interrupt pin.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to an earphone jack and its implementation method. Background technique [0002] As an accessory device of a mobile phone, earphones are generally equipped with earphones, through which users can easily listen to music, answer calls, listen to FM and so on. At present, the design of the headphone socket on the mobile phone is also designed according to the standard 3.5-inch headphone. It will bring some ESD (Electro-Static discharge: electrostatic discharge) problems. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] The object of the present invention is to provide a kind of earphone socket and its realization method, it can improve the ESD protection of earphone socket, prevent the mobile phone baseband chip from being damaged by electrostatic discharge; And can overcome the POP noise that earphone p...
