<p><P>PROBLEM TO BE SOLVED: To provide a glass breaking sound detection device reducing parts count and the number of installation processes, and reducing cost. <P>SOLUTION: The device is equipped with a sound sensor 2 comprising a speaker of an audio device 4 mounted in a vehicle A and a glass breaking sound detection circuit 3 for detecting if the sensor signal inputted from the sound sensor 2 is the breaking sound of a glass G of the vehicle. Consequently, the additional sound detection means (a microphone) is not required, and the parts count and the number of installation processes can be reduced. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
