Abstract

The invention discloses a percussion instrument with a sound cavity. The percussion instrument comprises an instrument frame main body and a percussion hammer, wherein a top surface of the instrumentframe main body is provided with an instrument piece; the knocking hammer comprises a spherical hammer body arranged at the front end of the knocking hammer, a knocking rod is fixed to the middle of the spherical hammer body, and the tail end of the knocking rod is designed to be semicircular; the piano frame main body comprises a bottom plate, side plates are fixed at the periphery of the bottomplate, and the side plates and the bottom plate form a sound cavity with an upward opening; the top of the sound cavity is provided with a plurality of musical instrument sheets through musical instrument nails. Due to the arrangement of the sound cavity, sound waves generated when the piano piece is knocked can touch the inner wall of the sound cavity and then return to the air, the sound waves rotate in the sound cavity to form a simulated echo state, and the sound generated when the piano is knocked is more lively, mellower and more pleasant to hear.

Description

technical field [0001] The invention relates to the technical field of percussion instruments, in particular to a percussion instrument with a cavity.
