Method of retrofitting a harmonica

摘要

A harmonica with a tube plate that provides production of sweeter, clearer notes with a minimum of skill. The tube plate has a plurality of tubes and sits over the reeds and the comb under the cover plate, a tube coupled with each air chamber in the comb. The tubes form tunnels with the air chambers, enhancing reverberation and separating the sound waves emanating from the reed in each chamber. The tube plate can be added to a conventional harmonica. The harmonica has a plurality of reed units, each reed in a separate unit. Each reed unit is individually replaced when a reed requires replacement or when modification of the harmonica key is desired. The reed units can replace a reed plate in a conventional harmonica.

1. A method of retrofitting a harmonica having a comb having a mouthpiece side and having an opposing front side, a reed plate mounted onto the comb, a cover plate secured to the comb with a plurality of fasteners, the comb having a plurality of individual air chambers, each extending substantially between the mouthpiece side and the front side, using a tube plate having a mouthpiece side and an opposing front side, the tube plate having a pair of opposing ends and includes a plate portion that is substantially planar at the opposing ends, the tube plate having a plurality of tubes extending between the mouthpiece side and the front side of the tube plate and tapered toward the mouthpiece side of the tube plate and the plurality of tubes are closed at the mouthpiece side of the tube plate, comprising the steps of:
removing the cover plate from the comb by un-securing the plurality of fasteners; positioning the tube plate against the reed plate and over the comb with the front side of the tube plate aligned with the front side of the comb, wherein each of the plurality of tubes is aligned with one of the plurality of individual air chambers; and securing the tube plate against the comb by trapping the tube plate between the comb and the cover plate by re-securing the cover plate to the comb using the plurality of fasteners.
