Description

a thumb piano

technical field

The present application relates to the technical field of musical instruments, and in particular, to a thumb piano.

Background technique

The thumb piano in the prior art is composed of a number of shrapnel of different lengths, and the shorter the shrapnel, the higher the pitch; each shrapnel takes the center C, the longest shrapnel in the middle, as the lowest tone, and the center is placed in the center on the principle of first left and then right. The two sides of C are arranged in the order of the scale of DEFGABCDEFGAB, that is, the order of the scales of the shrapnel from left to right in the two octaves is: BGECAFDCEGBDFA, and so on; The connection line is V-shaped; when tuning, the pitch of each shrapnel can be adjusted by changing the distance between the bridge and the toggle end of the shrapnel by hitting the shrapnel with a tuning hammer.

However, the above technical solutions have the following defects:

(1) Each shrapnel on the existing thumb piano is installed in the depression hole provided on the bridge, and the tuning is achieved by hitting the shrapnel with a tuning hammer; wherein, when the toggle end of the shrapnel The shorter the distance to its corresponding pressing hole, the higher the pitch of the shrapnel; however, when the tuning hammer is beating a shrapnel, since all shrapnel are installed on the same bridge; therefore, when the tuning hammer is beating a certain shrapnel, the When a certain shrapnel vibrates, it will easily cause the resonance of other shrapnel, and cause other shrapnel to shift their positions at the same time. As a result, each shrapnel needs to be tuned repeatedly. This process is not only time-consuming, but also When the user hits the shrapnel, the distance that the shrapnel moves each time is inconsistent due to the problem of inability to accurately control the strength of each beating. Therefore, the existing thumb piano also has the problem that it cannot be accurately tuned.

(2) Thumb pianos in the prior art are usually 5th, 7th, 10th, and 17th tones, and they are all composed of whole tones, without semitone keys, resulting in an incomplete range of sound, and it is impossible to play musical scores with semitones.

In conclusion, the thumb piano in the prior art still needs to be further improved.

The part of the shrapnel overlaps up and down, that is: the fixed end of the diatonic scale shrapnel is installed between the limiting part and the locking part of the second nut, and the free end of each diatonic scale shrapnel extends along its corresponding let the reed grass; therefore , this setting reduces the distance between the free end of the diatonic scale shrapnel and the free end of the chromatic scale shrapnel, which is convenient for the user to play and improves the user's experience; in addition, the setting of the limiter also plays a supporting role.

4. By passing the first fastener through the first assembly hole provided on the fixed end of the diatonic scale shrapnel and the second assembly hole provided on the first nut, the diatonic scale shrapnel can be fixed on the piano cavity .

5. By passing the second fastener through the third assembly hole provided on the fixed end of the chromatic scale shrapnel and the fourth assembly hole provided on the second nut, the chromatic scale shrapnel can be fixed on the piano cavity. .

6. By installing the first metal strip and the second metal strip on the first assembling groove on the first nut and the second assembling groove on the second nut, respectively, the diatonic scale shrapnel and the chromatic scale shrapnel are respectively pressed and installed. The way above the first metal strip and the second metal strip facilitates the sound of the diatonic scale shrapnel and the chromatic scale shrapnel.

7. By setting the corresponding sound name marks on both the diatonic scale shrapnel and the chromatic scale shrapnel, the user can quickly get started when playing to distinguish the pitch of each shrapnel.

8. By making the outer surface of the chromatic shrapnel black, so that the user can quickly distinguish the diatonic shrapnel and the chromatic shrapnel when playing, this setting not only improves the overall beauty of the thumb piano, but also improves the quality of the thumb piano to a certain extent. The design is close to the piano to enhance the user's experience.
