PURPOSE:To mount a microphone for aural pickup in an electronic watch by forming the microphone by utilizing a watch module. CONSTITUTION:A module 2 associated with a watch circuit, an electromechanical converter and an automatic tuner, etc. is mounted in a watch case 1. A microphone 1 for aural pickup having an electret type capacitor microphone and the like formed by utilizing the part of the moudle 2 is integrally associated with the module 2. When a time signal sound from a radio or the like is, for example, vibrated through a protection cover 8 at an elastic thin film 7, the sound thus produced by the vibration is transmitted to a microphone 5. The output signal from the microphone 5 is fed as a control signal to a time correcting circuit or the like. Thus, the microphone can be readily mounted at the small watch such as electronic wrist watch or the like. |
