A method and system (50) for inducing multi-frequency vibrations in a vibration propagating structure, for example a seat (52), is disclosed. The system is comprised of an acoustic vibration transducer unit (12) mounted on a relatively flat and rigid surface (54′) such that the direction of movement of an actuating element in the unit is parallel to the surface. When the unit is driven by an amplified low frequency audio signal a person sitting in the seat experiences vibrations. Additionally, a series of vibration propagating structures, for example a row of seats at a movie theatre, can be connected in series via vibration-propagating members (60) between adjacent seats thereby allowing a single acoustic vibration transducer unit to propagate vibrations to all connected seats.

What is claimed is: 1. A method of inducing multi-frequency acoustic vibrations in a vibration-propagating structure, comprising: positioning an elongate vibrating member generally parallel to and in physical contact with the structure; and producing in said elongate vibrating member the multi-frequency acoustic vibrations by deflecting an actuating element within and coaxial to said elongate vibrating member, wherein the actuating element induces the multi-frequency acoustic vibrations having frequencies and magnitudes related to those present in an input signal, the multi-frequency acoustic vibrations propagating both through said elongate vibrating member and the structure in physical contact with said elongate vibrating member to induce in the structure the multi-frequency acoustic vibrations, wherein the multi-frequency acoustic vibrations are inaudible. 2. A method of inducing multi-frequency acoustic vibrations in a series of vibration-propagating structures, comprising: positioning an elongate vibrating member in physical contact with a first one of the structures and in a direction generally parallel to the series of structures, said direction constituting a direction of propagation of the multi-frequency acoustic vibrations; interconnecting each pair of mutually adjacent structures of the series through an elongate vibration-propagating member generally parallel to said direction of propagation; producing in said elongate vibrating member the multi-frequency acoustic vibrations by deflecting an actuating element within and coaxial to said elongate vibrating member, wherein the actuating element induces the multi-frequency acoustic vibrations having frequencies and magnitudes related to those present in an input signal; and propagating the multi-frequency acoustic vibrations in said direction of propagation from said elongate vibrating member, the first structure, and the other structures of the series through said elongate vibration-propagating members, wherein the multi-frequency acoustic vibrations are inaudible. 3. A system for inducing multi-frequency acoustic vibrations in a vibration-propagating structure, comprising: an elongate vibrating member for being positioned generally parallel to and in physical contact with the structure; an actuating element within and coaxial to the elongate vibrating member; and a generator of the multi-frequency acoustic vibrations connected to said elongate vibrating member; wherein, in operation, said generator produces the multi-frequency acoustic vibrations in said elongate vibrating member by deflecting the actuating element within said elongate vibrating member, wherein the actuating element induces the multi-frequency acoustic vibrations having frequencies and magnitudes related to those present in an input signal, and the multi-frequency acoustic vibrations propagate both through said elongate vibrating member and the structure in physical contact with said elongate vibrating member to induce in said structure the multi-frequency acoustic vibrations, wherein the multi-frequency acoustic vibrations are inaudible. 4. A vibration inducing system as defined in claim 3, wherein said generator is mounted within said elongate vibrating member to form an elongate acoustic vibration transducer unit. 5. A vibration inducing system as defined in claim 4, wherein: the vibration-propagating structure comprises a seating unit with cushions; and said elongate acoustic vibration transducer unit is adapted to be positioned parallel to and transversally of said seating unit between said cushions of said seating unit. 6. A vibration inducing system as defined in claim 4, wherein: the vibration-propagating structure comprises a seating unit with a backrest having a rear face; and said elongate acoustic vibration transducer unit is fastened horizontally and transversally to said rear face of said backrest, said elongate vibrating member extending generally parallel to said rear face of said backrest. 7. A system for inducing multi-frequency acoustic vibrations in a series of vibration-propagating structures, comprising: an elongate vibrating member for being positioned in physical contact with a first one of the structures and in a direction generally parallel to the series of structures, said direction constituting a direction of propagation of the multi-frequency acoustic vibrations; an actuating element within and coaxial to the elongate vibrating member; a generator of said multi-frequency acoustic vibrations connected to said elongate vibrating member; an elongate vibration-propagating member for interconnecting each pair of mutually adjacent structures of the series, said elongate vibration-propagating member being generally parallel to said direction of propagation; wherein, in operation, said generator produces the multi-frequency acoustic vibrations in said elongate vibrating member by deflecting the actuating element within said elongate vibrating member, wherein the actuating element induces the multi-frequency acoustic vibrations having frequencies and magnitudes related to those present in an input signal, and the multi-frequency acoustic vibrations propagate in said direction of propagation from said elongate vibrating member, the first structure, and the other structures of the series through the elongate vibration-propagating members, wherein the multi-frequency acoustic vibrations are inaudible. 8. A vibration inducing system as defined in claim 7, wherein said the elongate vibrating member is cylindrical. 9. A vibration inducing system as defined in claim 7, wherein said generator is mounted within said elongate vibrating member to form an acoustic vibration transducer unit. 10. A vibration inducing system as defined in claim 7, wherein said elongate vibration-propagating members are tubular. 11. A vibration inducing system as defined in claim 7, wherein: the vibration-propagating structures each comprise a seating unit with a backrest having a rear face; and said elongate vibrating member is fastened to said rear face of said backrest of one of said seating units corresponding to said one structure, said elongate vibrating member extending generally parallel to said direction of propagation of the multi-frequency acoustic vibrations. 12. A vibration inducing system as defined in claim 7, wherein: the series of vibration-propagating structures comprises a row of seating units each having a backrest with a rear face; and said elongate vibration-propagating members each interconnect said rear faces of said backrests of two adjacent seating units corresponding to one pair of mutually adjacent vibration-propagating structures, said elongate vibration-propagating members extending generally parallel to said direction of propagation of the multi-frequency acoustic vibrations.
