    摘要: An apparatus and a method for detecting vibration are disclosed. The apparatus comprises a housing, a magnetic structure forming a magnetic field in the housing, and a coil structure in the magnetic field, concentric of the magnetic structure. In response to external vibration, the coil structure and the magnetic structure are movable with respect to each other. The coil structure comprises at least two sets of coils overlapped in space, of which a first coil set is for detecting vibration and a second coil set is for applying control in accordance with a control signal.
