The system includes one or more tactile audio transducers. A processor is configured to generate signals that drive the transducers in to generate audio waves in the medium when the transducers are applied to the medium and cause displacement of the mass or reformation of the mass. The method includes applying one or more tactile audio transducers to the medium; and driving one or more of the tactile audio transducers to generate audio waves in the medium to cause displacement of the mass or reformation of the mass. ## Claims ### Claim 1 A system for displacing or reforming a mass within a body medium comprising: (c) one or more tactile audio transducers; (d) a processor configured to generate signals that drive the transducers in a predetermined fashion to generate audio waves in the medium when the transducers are applied to the medium and cause displacement of the mass or reformation of the mass. ### Claim 2 (depends on 1) The system according to claim 1, wherein one or more of the transducers are adapted to be applied to a surface overlying the medium. ### Claim 3 (depends on 1) The system according to claim 1, wherein one or more of the transducers are adapted to be embedded or implanted in the medium. ### Claim 4 (depends on 1) The system according to claim 1, wherein one or more of the audio waves is a symmetric wave. ### Claim 5 (depends on 1) The system according to claim 1, wherein one or more of the audio waves is an asymmetric wave selected from one of the group consisting of: (d) a waveform having a rapid buildup of pressure followed by a slower release of pressure; (e) a wave train in which a first time interval of constant first pressure is followed by a second time interval of a second pressure, the second pressure being lower than the first pressure. and (f) a waveform in which buildup of the wave is complex and comprises a modulated attack form and modulated release. ### Claim 6 (depends on 1) The system according to claim 1, comprising a plurality of transducers wherein the transducers are positioned in an array producing a synergetic effect on the mass based on relative positions of the transducers in order to focus the waves on the mass. ### Claim 7 (depends on 1) The system according to claim 1, comprising a plurality of transducers wherein the transducers are positioned in an array producing a synergetic effect on the mass based on relative positions of the transducers applying asymmetric waveforms in order to induce directional movement of the mass. ### Claim 8 (depends on 1) The system of according to claim 1, wherein the transducers are incorporated into a wearable device. ### Claim 9 (depends on 1) The system according to claim 1, wherein one or more of the transducers are adapted to be positioned separated from the body, and the system further comprises one or more rigid elements that convey the audio waves from the transducer to the medium. ### Claim 10 (depends on 1) The system according to claim 1, wherein one or more of the signals include entertainment media. ### Claim 11 (depends on 1) The system according to claim 1, comprising a single transducer. ### Claim 12 (depends on 1) The system according to claim 1, wherein one or more of the transducers are embedded in a furniture item. ### Claim 13 (depends on 1) The system of claim 1, wherein one or more of the transducers are adapted to be applied onto the medium. ### Claim 14 (depends on 1) The system according to claim 1, wherein one or more of the transducers are adapted to be applied onto a body surface and one or more of the transducers is activatable to generate the waves in a direction parallel to the body surface. ### Claim 15 (depends on 1) The system according to claim 1, wherein one or more of the transducers are adapted to be applied onto a body surface and one or more of the transducers is activatable to generate the waves in a direction perpendicular to the body surface. ### Claim 16 (depends on 1) The system according to claim 1, wherein the system is configured to activate the transducers at two or more frequencies and waveforms to maintain or manipulate the medium or materials within the medium. ### Claim 17 A method for displacing or reforming a mass within a body medium comprising: (c) applying one or more tactile audio transducers to the medium; and (d) driving one or more of the tactile audio transducers to generate audio waves in the medium to cause displacement of the mass or reformation of the mass.
