Audio alarm system for vehicle use
First Claim
1. An audio alarm system adapted to be installed in a vehicle, the vehicle having a set of sensors disposed thereon, each of the sensors detecting presence of an associated event, said audio alarm system comprising:
- a control unit adapted to be connected electrically to the sensors and configured to generate a set of control signals, each of the control signals being generated by said control unit in response to detection of the presence of the associated event by a corresponding one of the sensors;
an audio processing unit having a set of alarm sound data stored therein, the alarm sound data being distinguishable from each other and corresponding respectively to the control signals, said audio processing unit being connected electrically to said control unit and, in response to the control signal received from said control unit, selecting the corresponding one of the alarm sound data; and
a loudspeaker connected electrically to said audio processing unit and operable so as to generate an audible alarm output corresponding to the alarm sound data selected by said audio processing unit.

Abstract
An audio alarm system is adapted to be installed in a vehicle, which has a set of sensors disposed thereon. Each of the sensors detects the presence of an associated event. The audio alarm system includes a control unit configured to generate a set of control signals, each of which is generated in response to detection of the presence of the associated event by a corresponding one of the sensors. An audio processing unit has a set of alarm sound data stored therein. The alarm sound data are distinguishable from each other and correspond respectively to the control signals. In response to the control signal received from the control unit, the audio processing unit selects the corresponding one of the alarm sound data. A loudspeaker generates an audible alarm output corresponding to the alarm sound data selected by the audio processing unit.

7. An audio alarm system for a vehicle having a set of sensors disposed thereon, each of the sensors detecting presence of an associated event, said audio alarm system comprising:
-
a main terminal adapted to be installed in the vehicle, said main terminal generating an audible alarm output in response to detection of the presence of the event associated with any one of the sensors when said main terminal is armed, said main terminal including a control unit adapted to be connected electrically to the sensors and configured to generate a set of control signals, each of the control signals being generated by said control unit in response to detection of the presence of the associated event by a corresponding one of the sensors, an audio processing unit having a set of alarm sound data stored therein, the alarm sound data being distinguishable from each other and corresponding respectively to the control signals, said audio processing unit being connected electrically to said control unit and, in response to the control signal received from said control unit, selecting the corresponding one of the alarm sound data, and a loudspeaker connected electrically to said audio processing unit and operable so as to generate the audible alarm output that corresponds to the alarm sound data selected by said audio processing unit; and
a remote controller operably associated with said main terminal to control arming and disarming of said main terminal. - View Dependent Claims (8, 9, 10, 11, 12, 13)
