COMPACT VIBRATION SENSOR

The present invention relates to a vibration sensor comprising a carrier substrate comprising a first surface and a second surface, a suspension member and a moveable mass secured thereto, wherein the moveable mass and/or at least part of the suspension member is/are adapted to vibrate when the vibration sensor is exposed to external vibrations, a read-out arrangement for detecting vibrations of the moveable mass and/or at least part of the suspension member, and a signal processor for at least processing an electric signal from the read-out arrangement, wherein the moveable mass forms a first projected area on a plane defined by the carrier substrate, and wherein the signal processor forms a second projected area on the plane defined by the carrier substrate, and wherein the first and second projected areas are, at least partly, spatially overlapping in the plane defined by the carrier substrate. The present invention further relates to a hearing device comprising such a vibration sensor, and use of the vibration sensor for voice recognition in a hearing device.
