Title: Radio selective calling receiver
Inventor: TADA KENICHI
IPC: H04W88/02
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To reduce fluctuation in vibration strength of a call notice vibrator even when a voltage of a DC power supply is fluctuated. SOLUTION: When a decoder 5 detects a calling, the decoder starts a call notice to a square signal generator 51. The started square wave signal generating circuit 51 generates a square wave signal Vs, a differentiation circuit 6 differentiates the square wave signal Vs to generate a differentiation signal Vf. When a voltage of the differentiation signal Vf is higher than a DC voltage Vp of a DC power supply 4, a comparator 7 produces a comparison signal Vc to turn on a transistor(TR) 9. When the TR 9 is turned on, a vibrator 10 connected between the DC power supply 4 and a collector of the TR 9 receives a square wave vibration drive signal to produce vibration. When the Dc voltage Vp is reduced, since a period for the differentiation signal Vf higher than the DC voltage Vp gets longer, the switch period of the TR 9 is increased and vibration drive power of the vibrator 10 is compensated.
