A handset microphone includes: a microphone unit, a first switch for turning on or off the output from the microphone unit, and a second switch for enabling or disabling the output from the microphone unit; the first and second switches have contacts operated by a magnetic field; the contact of the first switch is closed and short-circuits the output terminals while the first switch is being affected by the magnetic field; and the contact of the second switch is opened and disconnects one of the output terminals while the second switch is being affected by the magnetic field.
