1. A vibration sensor comprising:
a pressure generating element for generating pressure differences between a first volume and a second volume in response to vibrations of the vibration sensor, the first and second volumes being acoustically sealed from each other, wherein the pressure generating element includes a moveable element that is configured to interact directly with air of the first and second volumes; and
a pressure transducer for measuring pressure differences between the first and second volumes, wherein the pressure transducer and the pressure generating element are arranged in parallel relative to the first and second volumes, wherein the pressure generating element and the pressure transducer are arranged adjacent to each other such that the pressure generating element and the pressure transducer are directly exposed to portions of the first and second volumes.
