Description

A kind of random variable tone mouth organ

Technical field

The utility model belongs to a kind of musical instrument, particularly a kind of random variable tone mouth organ.

Background technology

At present, in traditional tongue musical instrument, modal is chromatic harmonica, but this musical instrument is little with volume, the solo that is easy to carry, (instrumental) ensemble, is more suitable for recreating by oneself and is subjected to people's favor deeply.It is by formations such as upper cover plate, upper and lower inflexion plate, sound lattice, reeds, the player by blow, inspiratory flow drives reed vibrations pronunciation, utilization is blown, long and short, strong, the weak control sounding of inspiratory flow size and length, the conversion of the conversion of tone, high bass utilizes inflexion plate control when playing wind instruments.Though by behind its playing technique on top of, solo or accompaniment smoothly, along with the continuous development of playing technique, it can not adapt to the needs of performance.

Summary of the invention

The utility model has overcome the defective of above-mentioned existence, and purpose is for the mouth organ in the tongue musical instrument can adapt to the changeable needs of playing of arranging performances, and provides a kind of playing method simple, is adapted at the changeable random variable tone mouth organ that uses when playing of arranging performances.

The random variable tone mouth organ content Description of the utility model:

The random variable tone mouth organ of the utility model, it is characterized in that: be by skeleton, soundboard, reed, shell, sound lattice, blowing strip, on arrange the sound lattice, arrange sound lattice, upper sounding board and lower soundboard down and constitute, skeleton, soundboard, reed, shell, sound lattice and blowing strip fitted together constitute random variable tone mouth organ; Skeleton is trapezium structure, and the top of skeleton is provided with blowing strip, and both sides are sound lattice, and reed is arranged between upper sounding board and the lower soundboard; Putting in order of reed scale on the upper sounding board of the row's of being arranged on sound lattice is: C ^#, D ^#, F, G, A, B, C ^#, D ^#, F, G, A, B, C ^#, D ^#, F, G, A, B, C ^#, D ^#, F, G, A, B, C ^#, D ^#, F, G; The putting in order of reed scale that is arranged on down on row's sound lattice lower soundboard is: C, D, E, F ^#, G ^#, A ^#, C, D, E, F ^#, G ^#, A ^#, C, D, E, F ^#, G ^#, A ^#, C, D, E, F ^#, G ^#, A ^#, C, D, E, F ^#

The utlity model has volume small and exquisite, be convenient for carrying, learn easily, arbitrarily variable tone mouth organ can become the guitar companion, boasts the song that arbitrarily blows out any accent from bullet with guitar.

Fig. 2 is the expansion synoptic diagram that puts in order of each scale reed on the soundboard

Among the figure: the 1st, skeleton, the 2nd, soundboard, the 3rd, reed, the 4th, shell, the 5th, sound lattice, the 6th, blowing strip, the 7th, last row's sound lattice, the 8th, following row's sound lattice, the 9th, upper sounding board, the 10th, lower soundboard.

Embodiment

The random variable tone mouth organ of the utility model is achieved in that to do below in conjunction with accompanying drawing and specifies.See Fig. 1, Fig. 2, arbitrarily variable tone mouth organ be by: skeleton 1, soundboard 2, reed 3, shell 4, sound lattice 5, blowing strip 6, on arrange sound lattice 7, arrange sound lattice 8, upper sounding board 9 and lower soundboard 10 down and constitute, skeleton 1, soundboard 2, reed 3, shell 4, sound lattice 5 and blowing strip 6 fitted together constitute random variable tone mouth organ.Skeleton 1 is trapezium structure, and the top of skeleton 1 is provided with blowing strip 6, and both sides are sound lattice 5, and reed 3 is arranged between upper sounding board 9 and the lower soundboard 10.Putting in order of reed 3 scales on the upper sounding board 9 of the row's of being arranged on sound lattice 7 is: C ^#, D ^#, F, G, A, B, C ^#, D ^#, F, G, A, B, C ^#, D ^#, F, G, A, B, C ^#, D ^#, F, G, A, B, C ^#, D ^#, F, G; The putting in order of reed 3 scales that is arranged on down on row's sound lattice 8 lower soundboards 10 is: C, D, E, F ^#, G ^#, A ^#, C, D, E, F ^#, G ^#, A ^#, C, D, E, F ^#, G ^#, A ^#, C, D, E, F ^#, G ^#, A ^#, C, D, E, F ^#

The playing method of the random variable tone mouth organ of the utility model and common mouth organ are basic identical, because skeleton is trapezium structure, the top of skeleton is provided with blowing strip, both sides are sound lattice, switch hole up and down by last lower lip, switch sound hole up and down and reach the effect of playing wind instruments whole tone and arbitrarily modifying tone, reach the effect of playing wind instruments whole tone and arbitrarily modifying tone by switching sound hole up and down, its two soundboards are consistent with the dimensions of common standard 20 octals, just done comprehensive change for pitch and the sound order of the reed that modifies tone, be different from any common mouth organ and no keynote variable tone mouth organ, can be in impromptu band, the song that occasions such as Karaoke are arbitrarily played wind instruments any accent, various accent all are a kind of methods of blowing of form, meet the music rule rise also easy especially, be that its range of 20 octals exceeds one and half octaves (common three octaves than common 20 octals equally, arbitrarily variable tone mouth organ is four and half octaves) as the gang that plays the guitar, just can become real guitar companion with going up the mouth organ frame, boast the song of arbitrarily blowing any accent from bullet with guitar, have: volume is small and exquisite, be convenient for carrying, learn easily, arbitrarily variable tone mouth organ can become the guitar companion, boasts the song that arbitrarily blows out any accent from bullet with guitar.
