Title:
ANNUNCIATOR
Document Type and Number:
WIPO Patent Application WO/1998/057761
Kind Code:
A1
Abstract:
An annunciator capable of annunciating by means of both sound and vibration, which is provided with an annunciating unit (2) equipped with a first vibrating body which generates acoustic waves when the body is driven at an audible frequency by means of a first actuating signal and a second vibrating body which generates bodily sensible vibrations when the body is driven at a low frequency of several 100 Hz or lower by means of a second actuating signal and connected to an annunciating signal generating circuit (5) through a switch (59). The annunciating signal generating circuit (5) is equipped with a signal generating circuit (57) for sound which generates the intermittent first actuating signal that is repeatedly turned on and off at regular time intervals, a signal generating circuit (58) for vibration which generates the intermittent second actuating signal that is repeatedly turned on and off at regular time intervals, and a synchronous circuit (56) which shifts the turning-on periods of the first and second driving signals generated from the circuits (57) and (58) from each other. This constitution can prevent the abrupt increase of the power consumption of the annunciator.
