Title:
ALARM DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP2017043214
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an alarm device for vehicle that can improve criminal prevention.SOLUTION: An alarm device for vehicle 10 includes a transducer 11, a first circuit 10A and a second circuit 10B. The transducer 11 has a vibrator attached to an object included in a vehicle 1, and converts vibration and an electrical signal in an alternate manner. The first circuit 10A applies an oscillation signal, which is an electrical signal, on the transducer 11, thereby causing the vibrator to vibrate. The second circuit 10B detects an abnormal state of the vehicle 1 based on a vibration signal, which is an electrical signal generated by the transducer 11. If the transducer 11 receives an oscillation signal from the first circuit 10A, then the transducer 11 causes the vibrator to vibrate according to the oscillation signal, make the object vibrate, and emit an audible alarm tone. If the vibrator vibrates with vibration of the object, the transducer 11 converts vibration of the vibrator to a vibration signal and outputs the vibration signal.SELECTED DRAWING: Figure 1
