HARMONICA REED PLATE AND HARMONICA

Abstract

The present invention discloses a harmonica reed plate and a harmonica, and belongs to the field of musical instruments. The harmonica reed plate has different thicknesses by controlling reed slots. Specifically, a groove with fixed depth is milled on the opposite surface of the target reed slot for fixing the reeds so that the reeds obtain an optimal vibration thickness different from the thickness of the original material after fixation to customize an equivalent reed plate thickness for each reed slot (reed) without the need to select a compromised thickness to take into account all the reed slots like the traditional harmonica reed plate. The harmonica prepared by the above harmonica reed plate can realize the optimal vibration mode of bass and treble at the same time on one reed plate, and can control the deviation of timbre, volume and pitch, which is more conducive to playing.
