Abstract:
Do you know how a plane of material makes a sound? One person?may imagine that the whole plane moves quickly back and forth.?Another may imagine that only a part of it vibrates. You will be?surprised when you first use our system! As a wave induces an?undulating pattern on a string, a bending vibration induced by three?vibrators propagates on the plane and a beautiful two dimensional?pattern appears on the diaphragm. A sound that is emitted from?each part of the plane interferes with the other sounds, and the total?sound obtains beam-like directivity.
