Claim:
1. An earphone wire control device, comprising: a switching unit, a first signal generating unit, a second signal generating unit and a microphone; wherein the switching unit and the first signal generating unit are connected in series to form a first path; wherein the switching unit and the second signal generating unit are connected in series to form a second path; the first path, the second path and a microphone path where the microphone is located are connected in parallel; wherein the switching unit switches between the first path and the second path: and wherein when the switching unit turns on the first path, the microphone path is short-circuited, the first signal generating unit generates a recording start signal and cuts off the first path after generating the recording start signal; when the switching unit turns on the second path, the microphone path is short-circuited, the second signal generating unit generates a recording stop signal and cuts off the second path after generating the recording stop signal.
