Abstract

The invention relates to a drive-by-wire earphone for portable electronic equipment and a method for realizing drive-by-wire. The drive-by-wire earphone comprises an earphone connector, an earphone control part and an earphone receiving part which are connected by wires, wherein the earphone connector is provided with four pins, namely a common port ground wire, a microphone audio cable, a right channel wire and a left channel wire from a position close to a wire end in turn; the microphone audio cable are connected in series with a microphone and the two ends of the microphone are connected in parallel with a key so as to form a microphone control circuit; and at least one group of function control circuit formed by serially connecting a resistor with a key switch is connected in parallel beside the microphone control circuit. The invention can save the production cost, can realize functions of the drive-by-wire earphone simultaneously, such as music play control, volume control, get through and hang up, start and stop of a radio and radio station search by increasing or decreasing frequency, and can be realized on any mobile phone platform.

Description

technical field [0001] The invention relates to a wire-control technology of a portable electronic device, more specifically, a wire-control earphone for a portable electronic device and a method for realizing wire-control. Background technique [0002] At present, 2.5mm / 3.5mm interface earphones are one of the most common earphones on the market, used for listening to music, listening to radio, answering calls and so on. In 2009, the state promulgated new standards, stipulating that from September 1st, the headphone jacks of mobile phones will be unified as round-headed 2.5mm and 3.5mm headphones. It can be seen that 2.5mm / 3.5mm interface earphones will become more common in the future and become an indispensable product for users of portable electronic devices. 2.5mm / 3.5mm wire-controlled earphones means that the user can control music playback and volume adjustment, connect and hang up the phone, start and stop the radio, increase and decrease frequency search stations a...
