Disclosed is a watch with a microphone. The watch includes a watch body and a voice input part. The watch body includes a control unit, an interface unit, a signal amplifying unit, a power supply, a power-supply transmission coil unit, a signal reception coil unit and a power-supply transmission unit. The voice input part includes the microphone, a signal transmission coil unit, a power-supply reception coil unit and a power-supply reception unit. When voice signals are input, an initial work voltage is provided to the microphone by the power supply so as to convert the voice signals into electrical signals which are then coupled to the control unit via the signal transmission and reception coil units and thus corresponding functions are executed. The electrical signals are also coupled to the power-supply reception unit via the power-supply transmission and the power-supply reception coil units so as to supply power to the microphone. Through use of the watch with the microphone, the voice signals and voltage signals are transmitted through coupling of the coil units so that power is supplied to the microphone and thus a technical problem that the thickness of the watch is increased correspondingly when the microphone is added and that the electricity of a cell of the watch is consumed when the microphone is driven to work is solved.
