Abstract
A loudspeaker comprising a resonant panel-form member adapted to produce an acoustic output and a vibration exciting system on the panel-form member and adapted to apply bending wave energy thereto, characterized in that the vibration exciting system is adapted to apply a bending couple to the panel-form member.
Claims22
A loudspeaker comprising:
- a panel-form member mounted on a suspension;
- and
- a vibration exciting system mounted on the panel-form member;
- the vibration exciting system being adapted to apply bending wave energy to the panel-form member and cause resonance, thereby producing an acoustic output;
- wherein the suspension acts as a pivot, thereby supporting the panel-form member in a simple fashion and causing nodal lines corresponding to the resonance of the panel-form member to move towards an edge of the member as compared to a generally corresponding but resiliently or freely edge-suspended panel-form member;
- the vibration exciting system being positioned so as to bridge across several of said nodal lines.
