Description

The invention relates to the production of plucked musical instruments.

The purpose of the invention is to provide the possibility of obtaining a tool with specified frequency characteristics.

FIG. 1 shows a plucked musical instrument assembly; in fig. 2 - tool body, horizontal section.

The pinch musical instrument contains the body formed by the side 1 and the decks 2, the neck 3 with the pegs 4, the stand 5 and the strings 6. The side 1 is made integral. Parts 7–9 of the sides 1 are joined to each other at the points where its concave parts transition into convex angles from 0 ° to 2 liters / 3 with the vertices f, e, c, b directed inward of the body. The tool has inserts 10 for joining the sheath parts 7-9.

A pinch musical instrument is manufactured as follows.

In the section a, b, the tool has an integral part 8 of the shell convex with respect to the longitudinal axis of the body, and its curved end is connected with the concave part 7 of the shell. In the tangent of L, the tangents at the end of the first and beginning of the second parts of the shells form a given angle, l.

In the section be, of the concave second part 7 of the shell and the third cd, the end of the second part 9 of the shell is joined to the curved end of the convex third part of the shell and form at a point with an angle made up of tangents at the end of their connection

In the section de and ef, the curved end of the convex part of the shell de is connected to the concave part of the shell ef at the point /. A predetermined angle is formed, l.

Similarly, the end of the concave part of the shell ef is connected with the curved end of the convex part of the shell fa, thus forming at the point f the angle f4еС,

Meng angles ff f2, fz, f4, as well as giving different sizes of convex, concave, receive various forms of the device.

At the points b, c, e, f, the ends of the parts of the shells are fastened with inserts 10, for example wooden

At constant values of the volume and shape of the middle part, bounded by the concave parts of the shells, be and ef. the shape and volume of the upper part change (increase or decrease) due to the elongation of the amb, anf, cgd, dhe portion

Claims (2)

1. A pinch musical instrument containing a body formed by the shells and decks, a neck with pegs, a stand and strings, characterized in that providing the possibility of obtaining a tool with specified frequency characteristics, the shell is made of composite, while the concave parts of the shells are joined with convex at an angle, the apex of which is directed inside the tool body and the angle of the joint is in the range of up to 0 ° to 2p / 3. 2. A tool according to claim 1, characterized in that the angle between the shells is sealed by an insert. FIG A
