Abstract
A pad for musical wind instruments with improved acoustic qualities. The acoustical improvement is achieved by providing a superior sound reflecting surface on the film or skin of the pad that engages with the tonehole. A lubricant for the sealing surface of the pad to prevent the pad from sticking to the tonehole rim. An outer retaining ring used to fasten the film to the pad while an inner collar supports the film and helps to create a smooth pad with a flat surface.
Claims20
A pad assembly, receivable within a cup, for removable engagement with the tonehole rim of a musical instrument comprising:
- a compliant disc shaped cushion disposed in said cup;
- a film layer adjacent to said cushion for engaging said tonehole;
- said film having a hard coating.
A method for bonding a hard layer of material to the tonehole engaging pad surface of a musical wind instrument, comprising the steps of:
- coating a layer of film with an adhesive;
- applying a layer of hard material to the adhesive so that it bonds to said film;
- positioning the combination of said film and said hard material so that they cover the cushion of said pad on the side of said cushion that engages with the tonehole of said instrument.
A pad assembly, receivable within a cup, for removable engagement with the tonehole rim of a musical instrument comprising:
- a rigid disc for insertion into said cup, said disc having a first surface adjacent to said cup, an opposite second surface adjacent to a cushion, and a circumferential edge between said first and second surfaces;
- a film layer in contact with said cushion for sealing engagement with said tonehole rim;
- said disc having an outer peripheral collar for insertion into said cup;
- said outer peripheral collar being juxtaposed laterally to the outside of said edge and said film;
A pad assembly, receivable within a cup, for removable engagement with the tonehole rim of a musical instrument comprising:
- a rigid disc for insertion into said cup, said disc having a back surface adjacent to said cup, an opposite front surface adjacent to a cushion, and a circumferential edge between said front and back surfaces;
- a film layer in contact with said cushion for sealing engagement with said tonehole rim;
- said disc having first and second coaxial collars for insertion into said cup;
- said first collar being an outer peripheral collar and said second collar being an inner collar;
- said outer peripheral collar being juxtaposed laterally to the outside of said edge and said film;
