Abstract

The utility model relates to a marimba. The marimba comprises a marimba base, a vertical support, marimba boards and sound tubes, wherein the vertical support is mounted on the bottom surface of the marimba base; the plurality of sound tubes are hung in the marimba base; each marimba board is mounted above each sound tube through an elastic fixing part in a contraposition manner; the plurality of marimba boards form a bass part, an alto part and a pitch part; upwardly curved bent parts are integrally formed at the lower end parts of the sound tubes in contraposition with the bass part; and a piston plate is coaxially mounted in each bent part. The marimba has a simple structure and is low in cost; owing to the additional arrangement of the bent part at the lower end of the sound tube in contraposition with the bass part, the total length of the sound tubes can be designed longer, and the marimba can cover a wider range to achieve more abundant expressive force; and the piston plates coaxially mounted in the bent parts can be adjusted to change the tone of the sound tubes at the bass part, and to further improve the playing effect of the marimba.

Description

Marimba

Technical field

The utility model belongs to the percussion instrument apparatus field, especially a kind of marimba.

Background technology

Malin's crust is a kind of African xylophone that is derived from, and structure has very big difference with general European xylophone.Though the kind of Malin's crust is a lot, but its basic structure is the same, include qin seat, vertical rack, qin plate, sound pipe, vertical rack is installed in the bottom surface of qin seat, hang in the qin seat and be provided with a plurality of sound pipes, each sound pipe top all is equipped with the qin plate by the flexible fastening piece contraposition, and a plurality of qin plates constitute basso, alto and high line.During performance, people's utilization is hit mallet and is knocked the qin plate, sounding under qin plate and the acting in conjunction of sound pipe, but because the sound length of tube of basso phase contraposition is longer, and the height of vertical rack can not improve arbitrarily, so basso can't contain low tone color, this has just limited the range that marimba showed, and is unfavorable for itself and modern cooperating of playing an instrument.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, cost is low and range is wide, the basso tone color is adjustable marimba is provided.

The purpose of this utility model is achieved through the following technical solutions:

A kind of marimba, comprise qin seat, vertical rack, qin plate, sound pipe, vertical rack is installed in the bottom surface of qin seat, hang in the qin seat and be provided with a plurality of sound pipes, each sound pipe top all is equipped with the qin plate by the flexible fastening piece contraposition, a plurality of qin plates constitute basso, alto and high lines, it is characterized in that: described and basso the sound pipe bottom one of contraposition are mutually made the kink that is bent upwards, the interior coaxial installation one piston sheet of each kink.

And end cap is installed in the upper end of described kink, and the end that the coaxial piston rod that installs in end cap, this piston rod stretch in the kink connects the piston sheet.

And the outside surface of described a plurality of kinks installs a reinforcement jointly.

Advantage of the present utility model and beneficial effect are:

The utility model is simple in structure, cost is low, described and basso the sound pipe bottom one of contraposition are mutually made the kink that is bent upwards, the adding of this kink makes very long that the total length of sound pipe can do, and makes marimba can contain bigger range, and expressive force is abundanter.And the adjustment of coaxial mounted piston sheet has realized that the tone color of basso sound pipe sounding changes, and has improved the playing effect of marimba in each kink.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of kink piston sheet.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.

A kind of marimba, shown in Fig. 1～2, comprise qin seat 3, vertical rack 6, qin plate 1, sound pipe 4 and castor 8, vertical rack is installed in the bottom surface of qin seat, hang in the qin seat and be provided with a plurality of sound pipes, each sound pipe top all is equipped with the qin plate by flexible fastening piece 2 contrapositions, a plurality of qin plates constitute basso, alto and high line, innovation of the present utility model is: with basso mutually the sound pipe bottom one of contraposition make the kink 5 that is bent upwards, coaxial installation one piston sheet 13 in each kink.

Above-mentioned piston sheet has been realized moving up and down in kink by a thrust unit 7, in the present embodiment, the structure of thrust unit is as shown in Figure 2: end cap 12 is installed in the upper end at kink, the coaxial sleeve pipe 11 that installs in end cap, the end that the coaxial piston rod 10 that installs in this sleeve pipe, this piston rod stretch in the kink connects the piston sheet.

During use, the player grasps handle 9, moves up or down piston rod, and piston rod drives the piston sheet and moves, for guarantee tone color accurately, in the outer rim of piston sheet sealing ring 14 is installed.

In the present embodiment, install a reinforcement 15 jointly at the outside surface of a plurality of kinks.First sound pipe that kink is installed is than the low G that octave is later of central C.

The utility model is simple in structure, cost is low, the adding of kink makes very long that the total length of sound pipe can do, make marimba can contain bigger range, expressive force is abundanter, and the adjustment of coaxial mounted piston sheet has realized that the tone color of basso sound pipe sounding changes, and has improved the playing effect of marimba in each kink.

Claims

1. marimba, comprise qin seat, vertical rack, qin plate, sound pipe, vertical rack is installed in the bottom surface of qin seat, hang in the qin seat and be provided with a plurality of sound pipes, each sound pipe top all is equipped with the qin plate by the flexible fastening piece contraposition, a plurality of qin plates constitute basso, alto and high lines, it is characterized in that: described and basso the sound pipe bottom one of contraposition are mutually made the kink that is bent upwards, the interior coaxial installation one piston sheet of each kink.

2. marimba according to claim 1 is characterized in that: end cap is installed in the upper end of described kink, and the end that the coaxial piston rod that installs in end cap, this piston rod stretch in the kink connects the piston sheet.
