Abstract
An alarm tone generating circuit for generating and controlling the intensity of an alarm tone during radio paging operations in a radio paging receiver, as the power supply voltage of a battery varies over time. The alarm tone generating circuit for a radio paging receiver includes: a power supply for supplying an operational power supply voltage of the radio paging receiver to components circuits thereof; a power supply detection signal generator for detecting variations of the operational power supply voltage over time and for generating a power supply detection signal; and an alarm tone level controller for controlling, in response to the power supply detection signal, the intensity of the alarm tone generated during radio paging operations of the radio paging receiver.
