<P>PROBLEM TO BE SOLVED: To prevent degrading of accuracy in vibration detection even when an electronic component vibrating the board and a vibration detection sensor are mounted on the same board. <P>SOLUTION: An electronic device includes a board in which electronic components can be mounted on a first mounting surface and a second mounting surface being the rear surface to the first surface; a vibration detection sensor that is mounted on the first mounting surface of the board, and a vibrating electronic component that is mounted on the second mounting surface of the board and vibrates by being applied with a voltage. The vibrating electronic component is mounted on the second mounting surface of the board while avoiding an area just behind the area where the vibration detection sensor is mounted. <P>COPYRIGHT: (C)2012,JPO&INPIT |
