Embodiment 1

[0016] refer to figure 1 and figure 2 , a kind of arc polyphonic structure thumb piano component described in this embodiment, comprises amplifying box 1, and the top of described amplifying box 1 is respectively provided with first support column 2, second support column 3, third support column from left to right The supporting column 4 and the fourth supporting column 5, and the first supporting column 2, the second supporting column 3, the third supporting column 4 and the fourth supporting column 5 are all fixed on the top of the loudspeaker box 1 by fixing screws 6, the first supporting column The tops of a support column 2, the second support column 3, the third support column 4 and the fourth support column 5 are arc-shaped structures, which increase the comfort of playing. The first support column 2, the second support column 3 A plurality of lower unison keys 7 are all plugged into the cylinder of the third support column 4, and the right side lower surface of the l...

Embodiment 2

[0018] refer to figure 2 , On the basis of Embodiment 1, in order to achieve the purpose of reducing the pitch deviation that occurs when playing for a long time, this embodiment has carried out an innovative design, specifically, the first support column 2, the second support column 3, the first support column The tops of the three support columns 4 and the fourth support column 5 are all provided with limit projections; each lower unison key 7 and the upper unison key 8 are limited by the limit projections, so that each lower unison key 7 and the upper unison key There will be no horizontal shaking between the 8 keys, reducing the pitch deviation that occurs when playing for a long time

[0019] Principles of use and advantages: the tops of the first support column 2, the second support column 3, the third support column 4 and the fourth support column 5 are arc-shaped structures, so that the sequence of the lower unison key 7 and the upper unison key 8 Arranged in an arc,...

Abstract

The invention discloses an arc-shaped polyphonic structure thumb musical instrument component which comprises a sound amplifying box, and the top of the sound amplifying box is provided with a first supporting column, a second supporting column, a third supporting column and a fourth supporting column from left to right. The first supporting column, the second supporting column, the third supporting column and the fourth supporting column are fixed to the top of the loudspeaker box through fixing screws, and as a preferable technical scheme, the tops of the first supporting column, the second supporting column, the third supporting column and the fourth supporting column are of arc-shaped structures. A plurality of lower homophone keys are inserted into column bodies of the first supporting column, the second supporting column and the third supporting column, and a plurality of upper homophone keys are inserted into a column body of the second supporting column. By the adoption of the structure, the linear layout mode of the keys at present is improved, the tone sequences of the lower homophone keys and the upper homophone keys are arranged in an arc shape, the piano is suitable for movement of thumbs, and the conditions of soreness and fatigue of the muscles of the thumbs cannot occur when the piano is played for a long time.

Description

technical field [0001] The invention belongs to the field of musical instruments, in particular to a thumb piano component with a curved polyphonic structure. Background technique [0002] Most existing thumb pianos are made up of a piano seat, a bracing frame, a key fixing member, and a key. The thumbqin can emit multiple tones, and the different tones are generated from the positions of the sound stop points of the keys, and the sound stop points are fixed places between the keys and the key fixing members. The sound stop points are located at different positions where the key and the key fixing member are fixed, and in combination with the length of the key, sounds of different tones are produced. [0003] The keys of the thumb pianos in the market are arranged in a straight line. Since the human thumb has a certain arc when playing the piano, the thumb piano with a straight line layout will make the thumb feel uncomfortable when played for a long time. Conducive to the...
