The disclosed transducer the can transfer an audio signal into a full-spectrum tactile wave over a frequency of 10 Hz-2 KHz. Upper and lower springs of the transducer produce vibrations via a coil/magnet in a manner similar to a conventional speaker, but the transducer uses a novel arrangement of elements, such as two south-to-south coils and carbon fiber springs, so as to produce the vibrations tactilely. The transducers can be tuned for specific applications and can be attached or formed integrally with a support surface. When attached or incorporated into a chair, massage table or other human-support structure, the transducer creates a sonic environment that surrounds and permeates the body with vibration, providing a direct experience of mental desired states. When connected to any full fidelity sound system, a support structure, a full frequency response process promotes a state of relaxation in the listener.
