PROBLEM TO BE SOLVED: To provide a vibration detector capable of removing noise due to an air-borne sound.SOLUTION: In the vibration detector for detecting vibration by touching an object, switch means SW1, SW2 for actuating a vibration detection element 2 when touching the object, and stopping operation when separated from the object are provided. When the vibration detector is separated from the object, operation of the vibration detection element is stopped by the switch means, and thereby an air-borne sound is never picked up, and when the vibration detector touches the object, detection operation is performed by actuating the vibration detection element by the switch means. Consequently, noise due to air-borne sound can be removed. |
