Abstract
A wireless ear phone and a sound broadcasting method thereof are provided. The wireless ear phone includes a first signal sensor, an electromagnetic signal transmitter, a second signal sensor and a controller. The first signal sensor generates an environment light detection result by detecting an environment light. The electromagnetic signal transmitter transmits an interruptible electromagnetic signal. The second signal sensor is disposed on a transmission path of the interruptible electromagnetic signal, and the second signal sensor generates an electromagnetic signal detection result by detecting whether the interruptible electromagnetic signal or the environment light is received. The controller enables or disables an operation of sound broadcasting of the wireless ear phone according to the electromagnetic signal detection result. When the wireless ear phone is put into an ear of a user, the transmission path is cut-off by the ear of the user.
