Abstract
The utility model discloses a melodica, comprising a bottom case, a sound hole board, a mouthpiece, sealing skin, and keys. The sound hole board and the bottom case below form a closed sound chamber. An end of the sound chamber is communicated with the mouthpiece. The sound hole board is provided with a plurality of sound grooves, and a sound reed is disposed under each sound groove. The sealing skin is covered on the sound hole board, and the sealing skin is provided with slots corresponding to the sound grooves of the sound hole board. A plurality of keys are arranged on the slots in a one-to-one correspondence manner. The keys are movably connected with the bottom case through pivots. The bottom case and the mouthpiece are molded in an integrated injection manner. The sound hole board is disposed on the bottom case. The sound hole board forms the sound chamber with the bottom case. The sealing skin on the sound hole board seals the sound chamber. The keys are pressed on the sealing skin, and sealing with the sound grooves of the sound hole board and fitting with the sound grooves are better. Thus, the melodic is simple in structure, and has better tone quality.
Description
Technical field
the utility model relates to musical instrument field, is specifically related to a kind of melodica.
Background technology
Melodica is a kind of blowing instrument that has keyboard, in musical instrument classification, with mouth organ same class, all belongs to the blowing instrument of free spring.The keyboard that has similar piano above melodica, there is blow gun on side, can when playing, blow, and therefore also can be considered the keyboard instrument that can play wind instruments.Melodica is because volume is little, and lightly easily carries, and plays wind instruments easy to learnly, in music education, is popular.Mostly composition structure in the sealing sound chamber of melodica is to be formed by the sealing strip of drain pan, grill and grill surrounding at present, and sealing effectiveness is not good, and tonequality is bad, and part is many, and assembling is complicated.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of simple in structure, the melodica that tonequality is better.
The utility model is achieved through the following technical solutions:
Melodica, comprise drain pan, grill, blow gun, sealing skin and key, the drain pan of described grill and below surrounds sealing sound chamber, one end, sound chamber is communicated with blow gun, offers a plurality of pronunciation grooves on grill, and each pronunciation groove below is provided with tone reed, sealing skin covers grill top, on it, offer notch with the pronunciation groove correspondence position of grill, notch top is a plurality of keys of corresponding arrangement one by one, and key is flexibly connected with drain pan by fulcrum.
The further improvement project of the utility model is, below, described key middle part is provided with fulcrum bar, and fulcrum bar is set with spring, and spring is fixedly connected with drain pan; Described a plurality of key activity is installed on a transverse axis, and transverse axis two ends are fixed on drain pan.Thereby key pressed steadily, musical note discharges stable.
The utility model further improvement project is, one end riveted joint of described tone reed or be welded on the grill inwall of pronunciation groove one end, and it is contrary that tone reed opening direction and key are pressed extreme direction.Qin is strong separated with tone reed maximum space, and musical note discharges more smooth and easy.
The utility model further improvement project is that described sealing skin is that ethylene-vinyl acetate copolymer material is made.The sealing skin of this kind of material, sealing effectiveness is better, discharges tonequality more.
The utility model further improvement project is that described sound cavity wall is smooth wall.The unblocked power of air pressure stroke being blown into, plays wind instruments more laborsavingly, and tonequality is better.
The utility model further improvement project is that, for the ease of the little child play of mouth type, described blow gun end face is flat rectangle.
The utility model further improvement project is that the outer peripheral face of described blow gun is round and smooth arc, can not scratch lip, and face interlock is more comfortable.
The utility model further improvement project is, comprises the shell being comprised of upper casing and lower casing, and the button position of blow gun and key is exposed to outside shell, takes conveniently, and prevent that dust from entering in qin body while playing wind instruments, and outward appearance is beautiful more simultaneously.
The utility model further improvement project is that, for the melodica musical note that overlaps casing is discharged completely, on the upper casing of the strong top of described qin, spaced apart being provided with released sound groove.
While playing wind instruments, by blow gun, in sound chamber, blow, in sound chamber, form air pressure, press down one of them key one end, the other end has been lifted up, and air-flow is through grill, and reed vibration, discharges musical note.
The utility model compared with prior art, has following obvious advantage:
The utility model drain pan and blow gun integrated injection molding are shaped, and grill is arranged on drain pan, and grill and drain pan form sound chamber, the sealing skin of grill top is by the sealing of sound chamber, and key is pressed on sealing skin, better with the sealing of pronunciation groove, the laminating of grill, therefore simple in structure, tonequality is better.This kind of melodica compact conformation, comprises that volume is small and exquisite from " 5,6,7,1,2,3,4,5,6,7,1,2 " totally 12 scales, and the enough underage child study of scale is used.
