The invention relates to a
wireless earphone with an otacoustic function, which comprises a main frame and two ear hanging pieces. The earphone also comprises a
digital signal processor, a
servo end
wireless transmitting module and a
servo end
wireless receiving module, wherein the
digital signal processor is electrically connected with the
servo end wireless transmitting module and the servo end wireless receiving module; the two ear hanging pieces comprise a
microphone, a
loudspeaker, a guest end wireless transmitting module and a guest end wireless receiving module respectively, the guest end wireless transmitting module is electrically connected with the
microphone and the guest end wireless receiving module is electrically connected with the
loudspeaker; and the
microphone can receive sound
waves from the outside world and change the sound
waves into electronic signals which are then transmitted to the
digital signal processor through the guest end wireless transmitting module and the servo end wireless receiving module, and then the processed electronic signals are transmitted to the
loudspeaker to be converted into the sound
waves through the servo end wireless transmitting module and the guest end wireless receiving module.
