By adopting the above structure, the utility model, can produce simple and honest tone quality.

Description

A kind of novel thumb piano

Technical field

This utility model relates to musical instruments technical field, particularly a kind of novel thumb piano.

Background technology

Thumb piano is a kind of traditional instrument being derived from Africa, generally comprises resonance chamber, wooden square backing plate and 1-2 row and is with elastic steel disc. Bimanual thumb is pressed steel disc and is decontroled, sends sound by vibrating, and is mainly used in vocal accompaniment. The steel disc of existing thumb piano is solid construction. The tone color that the thumb piano of this structure is played is comparatively limpid, it is impossible to produce simple and honest tone color.

Utility model content

Problem to be solved in the utility model is the deficiencies in the prior art parts, it is provided that a kind of thumb piano that can produce simple and honest tone color.

This utility model is by realizing by the following technical solutions.

Manufacture and design a kind of novel thumb piano, including being with elastic steel disc body, wooden square backing plate and resonance chamber, the left part of described steel disc body is oppressed above semicircle sleeper and metal cylinder by press strip and wood screw, the left part making steel disc body keeps tense situation, described semicircle sleeper is into a single integrated structure with the left part upper end of wooden square backing plate, described metal cylinder is arranged in the arc groove of the right part upper end of wooden square backing plate, of the present utility model it is mainly characterized by: the right part of described steel disc body is made up of upper half and lower half, described upper half is into a single integrated structure with steel disc body, the lower end edge length direction of upper half is provided with upside of ellipse connected in star, before described upside of ellipse connected in star, the lower end edge length direction of the wall thickness part at rear two ends is respectively equipped with elongated slot.

The length dimension of described lower half is identical with the length dimension of upper half and width dimensions respectively with width dimensions, the upper end edge length direction of lower half is provided with lower half oval-shaped groove, the upper end edge length direction of the wall thickness part at the forward and backward two ends of described lower half oval-shaped groove is respectively equipped with into a single integrated structure long raised line, and described long raised line adopts strong viscose glue to be adhesively fixed and fixes in elongated slot.

Described upside of ellipse connected in star and the right-hand member of lower half oval-shaped groove are provided with the plug of oval projection, by adopting the gluing fixing plug of strong viscose glue, make to form oval closed cavity between half and lower half.

This utility model, owing to adopting said structure, can produce simple and honest tone color.
