Patent ID: 7981064

Claim:
A method of inducing tactile stimulation of musical tonal frequencies in a cushioned transducer interface comprising: providing a transducer that generates vibrations in response to an electrical signal that is encoded with said musical tonal frequencies, such that said vibrations have a frequency that corresponds to said musical tonal frequencies; providing a first diaphragm disposed on a first side of said transducer that is mechanically coupled to said transducer so that said vibrations are transferred from said transducer to said diaphragm; providing a first foam layer that is capable of transmitting said vibrations having frequencies corresponding to said musical tonal frequencies; placing said first diaphragm in contact with said first foam layer to transfer said vibrations from said diaphragm to said first foam layer to induce the application of said tactile stimulation in a user that correspond to said musical tonal frequencies; wherein the providing a first diaphragm comprises providing the first diaphragm constructed of a composite material and that has spiral openings that extend to an edge of said first diaphragm to create lateral openings in the edge of the first diaphragm and to create elongated members.
