The embodiment of the invention discloses an earphone control device. The earphone control device comprises a micro control unit (MCU), an earphone and an analog switch. The input end of the MCU and the input end of the earphone are connected to an earphone socket of a terminal device in parallel, and the MCU is used for supplying power through a left microphone of the earphone socket and further used for performing two-way communication between the MCU and the terminal device through a right microphone of the earphone socket and a left / right channel. The analog switch is arranged on a sound channel line of the earphone, a general purpose input / output (GPIO) port of the MCU is connected with a switch control unit of the analog switch, and the switch control unit is used for turning on or turning off the analog switch according to switching signals of the GPIO port.
Description
technical field [0001] The embodiment of the present invention relates to the field of computer and communication technologies, and in particular to an earphone control device. Background technique [0002] With the development of computer and communication technology and the popularization of communication products, smart terminals have become an indispensable communication and entertainment tool for users, and have irreplaceable functions in people's daily life. For example, users usually use smart phones to answer calls or listen to music. [0003] As an important accessory of the smart terminal, the earphone plays a very important role in the application of the smart terminal. The existing four-segment earphone wire control has the function of one button or multiple buttons. For example, when the user uses the headset to make a call, he can answer or hang up through the buttons of the four-segment earphone wire control. When listening to music, the buttons of the four-...
