Abstract
A microphone includes a housing unit, a capsule unit mounted on the housing unit, a noise-counteracting unit electrically connected to the capsule unit with opposite electrical polarity, and a damping unit connected to the housing unit. The capsule unit generates a primary electrical signal composed of a primary signal part attributed to an acoustic wave and a secondary signal part attributed to a first mechanical wave which is generated due to vibration of the housing. The noise-counteracting unit generates a secondary electrical signal attributed to the first mechanical wave and having an electrical polarity opposite to that of the primary electrical signal, so that the secondary electrical signal may counteract the secondary signal part of primary electrical signal. The damping unit generates a second mechanical wave to counteract the first mechanical wave when the first and second mechanical waves are transmitted to the capsule unit.
