    Abstract: An alerting device which has an alerting unit (2) with a built-in vibrator resonated when receiving a driving signal and a signal generating circuit (5) which supplies a driving signal to the alerting unit (2). The signal generating circuit (5) generates the driving signal Dv whose frequency varies within a certain frequency range containing the resonance frequency of the vibrator and supplies the driving signal Dv to the alerting unit (2). The variation width of the frequency of the driving signal is predetermined in accordance with the variation width of the resonance frequency which is caused by the tolerances of the factors determining the resonance frequency. Further, the driving signal has an alternating rectangular or sinusoidal waveform and its frequency varies within a range of 1.37 - 2.98 Hz periodically. By the alerting device, a sufficient alerting effect can be obtained regardless of the variation of the resonance frequency of the vibrator.

    Abstract: This invention includes a square wave signal generating circuit 20 for generating a square wave signal whose frequency changes; a MOS transistor 12 which is turned on/off on the basis of the square wave signal to supply a driving current to a vibrator 14; and a frequency shift detecting circuit 24 for detecting a frequency shift between the square wave signal from the square wave generating circuit and a resonance frequency of the vibrator. The shift in the frequency generated by the square wave generating circuit is trimmed by a signal detected by the frequency shift detecting circuit.

    Abstract: The present invention relates to a method for driving an electrodynamic vibration device for outputting a vibration signal with a predetermined vibration strength for a mobile telecommunication means, whereby the electrodynamic vibration device is driven by an alternating current driving signal. The driving signal comprises time successive sinewave signals of varying periods, whereby the variation of the periods is set so, that the duration of each alternating current signal with constant period is shorter than 25 ms.
    Further, the present invention relates to a driving means (2) for driving an electrodynamic vibration device for outputting a vibration signal with a predetermined vibration strength for a mobile telecommunication means for carrying out this method.

    Abstract: A vibration-generating device that operates always following up the mechanical resonance point is disclosed. A vibration-generating device (1) is constituted by a vibration-generating unit (2) that comprises a magnet (11) and an electromagnetic coil (13) both fixed floatingly by a spring member (12), and the electromagnetic coil (13) is driven by a square-wave to generate vibrating power. The vibration-generating device (1) has a drive control unit (10) that monitors the driving voltage of the electromagnetic coil (13) at regular time intervals, increases the driving frequency of the electromagnetic coil (13) when the induced voltage waveform of the driving voltage increases with time and decreases the driving frequency of the electromagnetic coil (13) when the induced voltage waveform decreases with time. As a result, since the driving frequency of the electromagnetic coil (13) can be changed to the resonance frequency of the vibration-generating unit (2), the driving of the electromagnetic coil can always follow up the mechanical resonance point, and a large vibrating power can be obtained.

    Abstract: A relatively high voltage is developed across a buzzer (11) by placing a resistance in the discharge path of a buzzer, e.g., by shunting one or more Zener diodes or LEDs (14) across a switching transistor (12), the switching transistor being connected in series with the buzzer between a voltage potential and ground. Alternatively, the buzzer is shunted with a resistive element, with or without series connected reversed biased diode. The result is a higher audio output without a corresponding increase in power consumption.
