PURPOSE:To capture and report the generated vibration in all directions positively, by engaging a vibration aiding member to an object which detects the vibration. CONSTITUTION:The detecting body 1 is a spherical body and rolled in a detecting container 2. A microphone 3 is attached to the outer surface of the container 2. A shock absorbing structure is constituted by a spring 6 for the container 2 and a disk 7. The container 2 is eccentrically attached to the disk 7. The sensing structure, wherein the contact sound of the sensing body 1 and the container 2 is used as an input signal, is obtained in this way. |
