Abstract:
An acceleration-sensing system for sensing acceleration in a three-dimensional manner, said acceleration-sensing system comprising:a first acceleration-sensing unit sensing acceleration in a two-dimensional manner along first and second directions that are perpendicular to each other, wherein the first acceleration-sensing unit comprises a first electromagnetic converting element and a first magnetic force-generating part movable along the first and the second directions in accordance with acceleration; a second acceleration-sensing unit sensing acceleration in a one-dimensional manner along at least a third direction that is perpendicular to said first and second directions, wherein the second acceleration-sensing unit comprises a second electromagnetic converting element and a second magnetic force-generating part movable along the third direction in response to the acceleration; and a circuit board on which said first and second acceleration-sensing units are mounted.
