Abstract

The invention discloses an earphone interface compatible with a microphone function. The earphone interface comprises an earphone socket (2) and a seal device (3); a microphone (6) is arranged in the seal device (3), and the earphone socket (2) and the seal device (3) are fixedly mounted on a printed circuit board (1) respectively; a sound transmission hole (4) is formed in the earphone socket (2) close to the seal device (3); a sound picking hole (5) matched with the sound transmission hole (4) is formed in the seal device (3) close to the earphone socket (2). According to the invention, the sound transmission hole in the earphone interface is used as the sound picking hole for denoising MIC, so that the double-microphone denoising function is achieved without arranging additional sound picking hole in a cellphone casing, and the machining difficulty of the cellphone casing is reduced; the earphone interface does not affect the functions of the cellphone including anti-dust, anti-static and the like, is easy to implement, and is suitable for various cellphones.

Description

technical field [0001] The invention relates to an electronic product, in particular to an earphone interface compatible with a microphone function. Background technique [0002] A mobile phone, also known as a mobile phone, is a portable phone terminal that can be used in a wide range. The development of mobile phones is rapid. In just 40 years, mobile phones have developed into the 4G era. In addition to the most basic calling functions, current mobile phones can also be used to send and receive emails and short messages, surf the Internet, play games, take pictures and watch movies. Now, mobile phone has become a very important tool in people's life. [0003] However, when people use the functions of mobile phones, they are often troubled by some problems, such as: sudden power failure without charging conditions, small capacity of mobile phones, sudden failure of touch screen and noise, etc. Among them, noise has the most impact on people. frequently. Noise exists du...
