Abstract:
1. A harmonica comprising: a comb having a plurality of mouthpieces displaced from one another in the longitudinal direction, each of said mouthpieces being disposed upstream or downstream of a corresponding one of said cell sets in a first transverse direction relative to the longitudinal direction in terms of flow of blown air or drawn air, and being registered with the corresponding one of said cell sets; a reed vibrating member which has an elongated valve member which extends in the longitudinal direction, which is disposed in said comb, and which is shiftable relative to said comb in the longitudinal direction between diatonic and chromatic positions, said elongated valve member including a plurality of valve units which are displaced from one another in the longitudinal direction, and which are interposed between said mouthpieces and said cell sets, such that, in the diatonic position, each of said valve units blocks the air flow from a respective one of said mouthpieces into said second upper and lower cells of a corresponding one of said cell sets, and such that, in the chromatic position, each of said valve units blocks the air flow from the respective one of said mouthpieces into said first upper and lower cells of the corresponding one of said cell sets.
