Abstract

The utility model relates to a piano with a new type structure, belonging to the field of s musical instrument making technology. The utility model aims at enabling the timbre of a music box to be widely applied and expanding the music expression of a Mbira. The piano with reeds mainly comprises the reeds and soundboards, wherein the reeds are arranged in a piano manner, one ends of the reeds are fixedly arranged on the soundboards, and the other ends of the reeds are pulled by the fingers to emit notes of corresponding pitches so as to play songs with various melodies. Compared with the music box and the Mbira, the range of the piano can be expanded to more than five octaves, so that the piano can play more songs; compared with the piano in the prior art, the piano with the reeds is low in cost, relatively small in volume, small in occupying space, and convenient to carry.

Description

A kind of shell fragment piano

Technical field

The utility model relates to a kind of piano of Novel structure, belongs to musical instrument manufacturing technology field.

Background technology

Thumb piano (Mbira) is distributed widely in Africa, and the various places title is different, such as Kalimba, and Sanza, Kangombio, Leekembay etc.The sounding body of Mbira partly be exactly above resilient metal strip different in size one by one, the below then uses wood or bottle gourd as resonant tank.Mbira has a lot of different shapes, and the number of steel bar also not necessarily.

Music box is invented by the Swiss in 1796, and its pronunciation part is comprised of cylinder and reed two parts.The manufacture skill of music box is consummate, and its limpid, bright tonequality is brought beautiful enjoyment to people.The music box major part partly is comprised of power source (power sources such as clockwork spring or crank), sound cylinder, soundboard, damping, base plate, gear train etc.Principle is that power drives the sound cylinder uniform rotation that there is small embossment on the surface, can stir reed when projection process soundboard sound bar, makes reed send the sound of setting by the vibration frequency vibration of setting.A salient point on the sound cylinder is the equal of note on the music score, and the sound cylinder is done uniform rotation, and one has enough to meet the need and can play out one section melody.

Piano is a kind of keyboard instrument that is derived from the western classicality music, is comprised of 88 keys and metallic cord soundboard.The player affects the piano the inside wrapping the gavel of carpet by pressing the key on the lower keyboard, then knocks the steel wire string and sounds.

The thumb piano is similar to the principle of sound of music box, but thumb piano bond number is less, and key rehearsal mode differs, and has limited it and has played more melody.Music box is to have set fixing sound cylinder, is merely able to play fixing melody.

Summary of the invention

The utility model creates a kind of new-type piano, and its occurring principle and music box are similar, and playing mode and thumb piano are similar.

To achieve these goals, the utility model is arranged shell fragment according to the mode of piano, and shell fragment one end is fixed on the soundboard, and like this, finger is stirred shell fragment, just sends the note of the corresponding pitch of shell fragment natural frequency, the song that can eject various melody.About shell fragment, the material that can selector sum of fundamental frequencies rate requires is made shell fragment, and the profile of processing shell fragment, and its natural frequency is met the requirements.

The utility model is with respect to music box, thumb piano, and the range of shell fragment piano can be extended to five more than the octave, can play more song; With respect to piano, it is with low cost, and volume takes up room little with respect to small and exquisite, is easy to carry.

Description of drawings:

Fig. 1 is the shell fragment Pareto diagram of a unit, and 1 is shell fragment, and 2 is the shell fragment depression bar, and 3 is screw, and 4 are shell fragment pillow bar, and 5 is soundboard.

Fig. 2 is the shell fragment piano figure of five octaves.

Fig. 3 is the shell fragment piano figure of six octaves.

Embodiment

The present invention is further illustrated below by specific embodiment, and its purpose is to help better to understand content of the present invention, but the protection domain that these specific embodiments do not limit the present invention in any way.

A kind of new-type piano, by mainly being comprised of shell fragment 1 and soundboard 5, an end of shell fragment is fixed on the soundboard 5 by depression bar 2 and screw 3, and adjusting screw can be regulated fixing elasticity, and pillow bar 4 plays a part to support shell fragment, with the other end perk of shell fragment.

Soundboard can also connect resonant tank or directly be the panel of resonant tank.

The pitch of shell fragment is relevant with factors such as the length of shell fragment, thickness, shape, materials, specific to a shell fragment, can become flexible the screw on shell fragment both sides, regulates its length of stretching out and makes it to reach accurately pitch.During performance, finger is stirred the unfixed end of shell fragment, makes shell fragment send the vibration of its natural frequency, and transfers vibrations on the soundboard and speak.

Fig. 1 provides 2 kinds of arrangement modes, and common feature is to arrange identical in the pitch of piano key: there are 7 keys at the front row, and pitch is followed successively by and is C, D, E, F, G, A, B from left to right; Rear row has 5 keys, and pitch is followed successively by #C, #D, #F, #G, #A from left to right.Can not run on the front-seat depression bar during rear row's key vibration.In two kinds of arrangement modes: the mode on the left side is in order to make the shell fragment end that stretches out concordant; Be convenient to play, the mode on the right is saved material, makes relatively simple.Dual mode respectively has quality, uses as the case may be.

Fig. 2 is the shell fragment piano of five octaves, and its key is arranged by the right figure mode of Fig. 1.

Fig. 3 is the shell fragment piano of six octaves, and its key is arranged by the right figure mode of Fig. 1, is arranged in two row, with respect to the mode of Fig. 1, and the span about two row keys have shortened, and take full advantage of the position of soundboard.

Claims

1. shell fragment piano, it is characterized in that: it mainly is comprised of shell fragment and soundboard, and its button is shell fragment, and shell fragment is rehearsed according to the mode of fingerboard; Shell fragment one end is fixed on the soundboard, stir the other end can send shell fragment frequency pitch and drive soundboard resonance.

2. piano as claimed in claim 1, it is characterized in that: the material of shell fragment is selected from metal, plastics, timber or other resilient material; Shell fragment be shaped as sheet, shaft-like or the two assembly.
