发明名称 Electronic timepiece
摘要 A timepiece has a time set mode and another time-related mode. It comprises a logic circuit for recognizing the time set mode and an electroacoustic transducer responsive to the logic circuit for providing a particular sound in succession when the timepiece is in the time set mode. The present timepiece makes it easy for the user, especially a blind or weak-eyed person, to recognize that the time set mode is in effect.
