ELECTRONIC WRISTWATCH WITH ALARM

PURPOSE:To allow the skin of a human body to sense information such as a time or an alarm by directly transmitting vibration to the skin, by projecting a part of the alarm connected to a vibration plate vibrated by the signal from an alarm signal generating part through the orifice of a back lid. CONSTITUTION:The signal sent out to a driving control part 33 from the frequency dividing part 12 of an electronic wristwatch with an alarm is set to frequency generating vibration which is optimum to sense the vibration plate of a vibrator 42 by the skin, for example, 1-60Hz. A piezoelectric element 51 being the vibrator and a vibration plate 52 secured to said element 51 are received in the orifice 54 provided to the back lid of the wristwatch and the vibration plate 52 is projected to the outside from the back lid 50 to externally transmit vibration. In this case, the signal from an alarm signal generating part 30 is applied to the piezoelectric element 51 through a drive part 41 from a lead wire 53. In addition, a part of te vibration plate 52 may be projected from the orifice 54 provided to the back lid 50 of the wristwatch.
