Proposed are an earphone wire control device, an earphone, and a voice recording system and method. When a first path is connected through a switch unit (1), a microphone path is short-circuited, and a first signal generation unit (2) generates a recording startup signal, and cuts off the first path after generating the recording startup signal, so as to connect the microphone path; and when a second path is connected through the switch unit (1), the microphone path is short-circuited, and a second signal generation unit (3) generates a recording stopping signal, and cuts off the second path after generating the recording stopping signal. The embodiments of the present invention achieve that voice information can be recorded when a user presses down a key of a wire control device, thereby enhancing the earphone operability and laying a foundation for promoting the combination of an earphone with other devices. |
