Patent ID: 8617089

Claim:
A method of inducing tactile stimulation of musical tonal frequencies using a rigid diaphragm structure comprising: providing said rigid diaphragm structure; forming at least one first curved structure in a portion of said rigid diaphragm structure, said first curved structure having a curvature and thickness that causes said first curved structure to have a resonant, sympathetic frequency that responds to a first set of predetermined musical tonal frequencies; forming at least one second curved structure in a portion of said rigid diaphragm structure, said second curved structure having a curvature and thickness that causes said second curved structure to have a resonant, sympathetic frequency that responds to a second set of predetermined musical tonal frequencies that is different from said first set of predetermined musical tonal frequencies; attaching a first transducer to said rigid diaphragm structure that vibrates in a frequency range that corresponds to said first set of predetermined frequencies; attaching a second transducer to said rigid diaphragm structure that vibrates in a frequency range that corresponds to said second set of frequencies.
