Abstract
A device for enhancing enjoyment of electronically reproduced music including a chair with liquid-filled bladders coupled to transducers such as electromagnetic driver assemblies responsive to audio-frequency electrical signals. A diaphragm of elastic sheet material provides support for part of the bladder and part of the transducer. Bladders and transducers are located in the seat and back of the chair, and the transducers move the liquid in the bladders, so that movement of the liquid can be felt by a user sitting in the chair. The electrical signals are preferably filtered to pass only bass frequencies to the transducers.
