Adjustable resonance chamber for musical instrument

Abstract

The invention provides an adjustable resonance chamber for a musical instrument, and relates to a component used for amplifying sound in the musical instrument. The resonance chamber comprises a top plate, a bottom plate, side plates, a spring clamp, magnets, a movable partition board and a tone tuning module. The top plate, the bottom plate and the side plates are connected together through the magnets to constitute a chamber body. The bottom plate is sleeved within a space between the side plates and can slide up and down to change an internal space of the chamber body. A long hole is formed in the top plate, and the magnets are arranged on the half front portion of the top plate. The movable partition board is arranged between the top plate and the bottom plate, a handle is arranged on the movable partition board and penetrates out from the long hole in the top plate, the movable partition board is composed of two boards, upper sides of the two boards are connected by hinges to form a herringbone shape, the handle is arranged at the top end of the movable partition board, the top of the movable partition board is further provided with the spring clamp, and bottom edges of the two boards are provided with idler wheels. The tone tuning module is arranged on the lower portion of the front of the top plate and is a wedge-shaped solid-core plate, wherein a fracture surface of the wedge-shaped solid-core plate gradually thickens. By means of changes of the thickness of the tone tuning module and moving of the partition board and the bottom plate, the resonance chamber can conveniently and flexibly change timbres and tones.
