Abstract

A piano comprises a body, an iron framework, sound boards, strings, a string striker, a sound stop machine and a keyboard, which is characterized in that the iron framework is composed of the main and the secondary iron frameworks in which two structures are mutually symmetric. The backs of the frameworks are opposite and fixed through a plurality of joint levers. The strings are respectively arranged on the facades of the main and the secondary iron frameworks. The sound boards are respectively arranged on the dorsal of the main and the secondary frameworks, and a sound post is arranged between the sound boards. A code bridge is arranged between the string and the board. The string striker and the sound stop machine are corresponded to the strings of the main iron framework. The strings on the secondary iron framework are provided with the rear sound stop machine, and a link gear is arranged between the rear sound stop machine and the sound stop machine of the string striker. With the adoption of the utility model, the piano sound quality and sound effects can be improved, and the weight of the piano can be reduced as well.

Description

A kind of piano

One, technical field

The utility model relates to a kind of piano.

Two, background technology

The keyboard instrument that piano is a kind of range broadness, expressive force is abundant, mainly contain upright piano and horizontal piano, but its basic structure all is made up of casing of piano, back frame, iron skeleton, soundboard, string, hammered string instrument, keyboard and pedal system, iron skeleton and soundboard are even to be fixed on the back frame, string is arranged on the iron skeleton, by the gavel strike string of keyboard percussion hammered string instrument; Because the vibration of string is struck a chord soundboard, and improve the piano volume; For satisfying performance requirements such as piano sound and accuracy in pitch stability, its iron skeleton adopts cast iron to make, and the back frame is thick wooden one-tenth framework, thereby the qin body is heavier.

Three, summary of the invention

The purpose of this utility model is to improve the tonequality and the acoustics of piano, alleviates the qin body weight.

For achieving the above object, the technical solution adopted in the utility model is:

The utility model comprises qin body, iron skeleton, soundboard, string, hammered string instrument, sound stopping device and keyboard, be characterized in that described iron skeleton is made up of the symmetrical iron skeleton of major-minor two block structures, the iron skeleton back side is fixed relatively and by several connecting links, described string is located at the front of major-minor iron skeleton respectively, described soundboard is located at the dorsal part of major-minor iron skeleton respectively, be provided with sound column between the soundboard, be provided with a yard bridge between string and the soundboard; Described hammered string instrument and sound stopping device are corresponding with the string of main iron skeleton, and the string of described secondary iron skeleton is provided with the back sound stopping device, is provided with link gear between back sound stopping device and the hammered string instrument sound stopping device.

The utility model design feature is:

1, the utility model is set up a cover string on secondary iron skeleton, and the musical note of the string on every string and the main iron skeleton is identical, can cause string sympathetic response on the secondary iron skeleton during string vibration on the main iron skeleton, thereby overtone increases, the tonequality of raising piano.

2, the utility model is set up a soundboard at secondary iron skeleton dorsal part, can improve the volume of piano, constitutes sound box bodies simultaneously between qin body and the soundboard jointly, can improve the acoustics of piano.

3, the utility model major-minor iron skeleton is fixed as framed structure by pitman shaft, the major-minor iron skeleton can be repealed by implication because of the stress that fixing string produces, can guarantee that piano in performances such as tonequality, accuracy in pitch are stable, also saves heavy back frame simultaneously, alleviate the weight of piano.

Four, description of drawings

Described in detail below in conjunction with the utility model embodiment accompanying drawing:

Fig. 1 is the utility model embodiment upright piano structural representation;

Fig. 2 is the horizontal piano structural representation of the utility model embodiment.

Five, embodiment

See figures.1.and.2, the utility model comprises qin body 1, iron skeleton 2, soundboard 3, string 4, hammered string instrument 5 and keyboard 6, be characterized in that described iron skeleton 2 is by the symmetrical iron skeleton 2,2 of major-minor two block structures ' form, the iron skeleton back side is fixed relatively and by several connecting links 7, described string 4 be located at respectively major-minor iron skeleton 2,2 ' the front, described soundboard 3 be located at respectively major-minor iron skeleton 2,2 ' dorsal part, be provided with sound column 8 between the soundboard 3, be provided with yard bridge 9 between string 4 and the soundboard 3; Described hammered string instrument 5 and sound stopping device 52 are corresponding with the string 4 of main iron skeleton 2, described secondary iron skeleton 2 ' string be provided with the back sound stopping device 10, be provided with link gear 11 between back sound stopping device and the hammered string instrument sound stopping device.

With reference to Fig. 1, described hammered string instrument 5 is made up of sound mallet 51, sound stopping device 52 and link gear 53; Described back sound stopping device 10 is formed by ending sound 12, armed lever 13, axostylus axostyle 14 and retracing spring 15, and described online structure 11 is to be made of on line, and two ends are connected with the armed lever of hammered string instrument sound stopping device armed lever with the back sound stopping device respectively.
