Title:
ELECTROMAGNETIC BUZZER CONTROLLER FOR MOUNTING IN VEHICLE
Document Type and Number:
WIPO Patent Application WO/2006/103795
Kind Code:
A1
Abstract:
An electromagnetic buzzer controller for mounting in a vehicle, comprising a main switch (SW1) for selectively setting an alarm mode for security and a normal mode that is set after the alarm mode is cancelled, a sensor (7) for detecting inclination, vibration or impact of a vehicle, and a control circuit (6) for opening/closing, depending on setting of the main switch (SW1), a conduction path from a power supply to an electromagnetic buzzer. The control circuit (6) controls power supply such that, when an inclination etc. of the vehicle are detected by the sensor (7) while the alarm mode is set, the conduction path to the electromagnetic buzzer (3) is closed to emit a sound for alarm, and when a horn switch (SW2) is closed while the normal mode is set, the conduction path to the electromagnetic buzzer (3) is closed to emit a sound for safety confirmation, thereby the sound for alarm and the sound for safety confirmation are caused to be different. Thus, the sound of the electromagnetic buzzer used for ordinary safety confirmation and sound for alarm functioning as a security device are made to be different from each other so that they can be identified from each other.
