<P>PROBLEM TO BE SOLVED: To provide an impact and acoustic sensor that can detect both of impact and acousmato. <P>SOLUTION: An impact and acoustic sensor 1 includes: a first and a second piezo electric elements 16, 20 stored in a package 2; and a wiring structure. The first and second piezo electric elements 16, 20 are arranged such that they are deformed in a reversed-phase with respect to acousmato input and the same phase with respect to vibration input, and the wiring structure is configured such that output signals from the first and second piezo electric elements are supplied independently. <P>COPYRIGHT: (C)2012,JPO&INPIT |
