Abstract

The utility model relates to a xylophone. The utility model is characterized in that the xylophone is composed of a base 1, sound sheets 2 and positioning pieces 3, wherein the base 1 is a trapezoidal frame, two positioning holes 21 which form a shape like the inverted Chinese character 'tu' are arranged on the sound sheets, the sound sheets 2 are installed on the base by the positioning piece through the positioning holes, the positioning pieces 3 and the base 1 are integrally connected, a gap is reserved among the positioning pieces 3 and the sound sheets 2, and the lengths of adjacent sound sheets 2 are successively increased or successively reduced. The utility model has the advantages of compact structure, convenient manufacture and low price. Besides, the euphonic music can be played when the xylophone is struck.

Description

Xylophone

The utility model relates to a kind of percussion instrument, particularly a kind of xylophone.

Traditional xylophone body volume is bigger, carrying inconvenience, and processing, installation, debugging work load are big, and cost is also higher.

The purpose of this utility model provides a kind of xylophone of compact conformation, have simple for production, advantage such as price is cheap.

A kind of xylophone comprises body, hammer, it is characterized in that body is made of base 1, tablet 2, keeper 3, base 1 is a ladder-shaped frame, is made up of slanted bar 11 and crosspiece 12, and tablet 2 is arranged on the base 1, have two pilot holes 21 on each tablet, keeper 3 is installed in tablet 2 on the base 1 by pilot hole 21, and keeper 3 is connected as a single entity with base 1, leaves the gap between keeper 3 and the tablet, each adjacent tablet 2 its length increases progressively successively, or successively decrease successively; Pilot hole 21 is inverted convex shape, leave the axial clearance between the top of keeper 3 and tablet 2 bottoms and be not less than 4mm, keeper 3 radially and the gap between the tablet 2 be not less than 0.7mm, keeper 3 adopts screws, perhaps rivet etc., the upper sideline of tablet 2 transversal section is a camber line.Base and tablet all adopt timber to make, and tablet is the parts of pronunciation, and low, the short pronouncing frequency height of pronouncing frequency that tablet is long is arranged in order by its length, when impacting, can play melodious music, liked by children.

Fig. 1 is the design's an xylophone body structural representation.

Fig. 2 is the AA sectional drawing of Fig. 1.

Fig. 3 is the BB sectional drawing of Fig. 1.
