Abstract

A single-end fixed musical instrument is characterized in that the sounder including a pole, a bar or a board is fixed on a single end while the other end can freely stroke, the musical interval is adjusted by the length, the thickness and the hardness of the sounder, the sounder can be hard and can be wood, metal, ceramics, glass or jade, in which the key point is that the sounder must be integral with the strut-beam grillage except that the metal can be welded, and the musical instrument can be either large or small from basketball frame to music box, and the tone space has no limit.

Description

Inelastic single-ended fixed musical instrument

Coming a minute kind musical instrument with fixation, is to stand in the method that a kind of new visual angle and new thinking are examined musical instrument closely, and it generally can be divided three classes most of musical instruments.

(1), both-end fixed class, chord crying musical instrument in the world is the both-end fixed class mostly, as piano, guitar, urheen, Chinese lute, hard qin, dulcimer or the like, the unified feature of this kind musical instrument is, the pronunciation string all is a both-end---is that two is fixed, do not have free end, and string all is soft, can be crooked, resilient.

(2), empty end fixed class, so-called empty end promptly is not real fixing, or it is false fixing to say so, but want the limited activity of energy, this kind musical instrument is the body crying musical instrument entirely, as clock, single sonorous stone, Malin's crust, bamboo-board musical instrument, gong or the like, their characteristics are, their not to sling, will hang exactly and cushion, so that can freely tremble pronunciation, their entity almost is hard, inelastic entirely.

(3), single-ended fixed class, single-ended fixing, as the term suggests promptly one fixing, one is the free end pronunciation, mouth organ, accordion, clarinet, lock, sheng, a reed pipe wind instrument, music box, dialing spring box, comb all be this type of, mostly this kind musical instrument is the spring kind musical instrument, just patent---the hard string qin that will announce recently of the author, just added the string class to them, this kind musical instrument pronunciation spring or string are resilient entirely, at present, do not see inelastic single-ended fixed class musical instrument as yet.

Yet if the author finds the body crying musical instrument single-ended fixing when the hard string qin of development, equally can pronounce, as being fixed up xylophone is single-ended, it has just become atypical xylophone, has become a kind of qin that can add audio amplifier, the xylophone in past is only to divide into a long tube at soundboard, because the sound tube is not connected with soundboard, the effect of sympathetic response is matter so just, and audio amplifier is just different, it is can be close-connected, so the sympathetic response works very well.But also can a plurality of audio amplifiers as floor, the stack sympathetic response, thus obtain abundant more tone color, think of outstanding singer and use the sympathetic response together of nasal cavity, head cavity, thoracic cavity, abdominal cavity, just be not difficult to have understood the advantage of a plurality of audio amplifiers.And also can press from both sides one deck sound film in the audio amplifier, to change the in the past single practice with soundboard.The author adopts this method in the audio amplifier of hard string qin, unexpectedly obtained very marvellous tone color, this finds that just the sound film really than the tone color of soundboard, enrich manyly, has also confirmed bionical superior, because the many animals of nature, cry as frog, sandfly worm, katydid, cicada, katydid, cricket, field cricket can be so pleasing to the ear beautiful, and what be their employings entirely is the pronunciation of sound film, although the author's sound film only is a Rice ﹠ peanut milk, the rice paper of starching, but it is effective undoubtedly.

Certainly, will xylophone single-ended fixedly be relatively bothersome, only allowing soundboard closely be connected with the strutbeam grillage won't do, but to allow them itself be an integral body, naturally these need carve the soundboard support to come on a chunk of wood together, it is just much easy to handle to change metal into, except monoblock cast, also can weld or the spiral shell button is tightened, glass, pottery, jade and timber are the same, and soundboard and support also must be same one, and this is that wave mechanics determines, fortunately these materials, it is whole not so difficult to allow them become.

The benefit of single-ended fixed class musical instrument is, musical instrument is changeable, the musical instrument of same range, can be little to resembling music box, can arrive the framework of basketball again greatly, just use material, on length, thickness, soft or hard, adjust, because interval or say that frequency is to be decided by single-ended fixing chord member, soundboard, the length of sound bar, thickness, these variablees of soft or hard.

List a formula can for the frequency of cylindrical chord member here.

V is a frequency, and R is the straight warp of cylinder, and L is a length, and H is a hardness,

Be a single-ended fixing constant,

Be that Greek alphabet of the fluctuation scholar Schrodinger that uses, obscure, added one zero circle for unlikely.

In fact, this formula is of little use, because will regulate interval, can also increase the weight of the chord member head, or levigate root turns down sound, and vice versa.So we only need know, the chord member of equal length, thick more sound is high more, thin more sound is low more, or the chord member of equal length, thickness, be that soft sound is low, hard pitch has just become, grasped these knowledge, it is very easy making a single-ended fixed class musical instrument, such as the iron ladder of the children of kindergarten being climbed object for appreciation, transforms a little and welds, just can be made into one and can climb object for appreciation, can hit the dual-purpose equipment of playing music again.Since single-ended fixing, be that a bar is an interval, thereby not limited by range, want to adorn several octaves, with regard to several octaves, furthermore can also be back to dress, one side high pitch, on one side bass, convenient two hands, this past both-end or empty end musical instrument can't be compared, and at least, have only covered flexible and nonelastic with regard to single-ended musical instrument letter, just undoubtedly gene mutation at last, we know, the evolution of all things in the world is relevant with turning to of causing of sudden change invariably.

Below, provide an embodiment with regard to a single-ended fixed class brandreth qin.

Fig. 1: the front elevation that is a brandreth qin

Its acceptance of the bid (1) be tuning rod, tuning rod can be tubulose, strip, column or other shape.Mark (2) is strutbeam trestle or frame plate, and this also can adopt arbitrary shape.What mark (3) is a wooden soundboard, and plank only as sympathetic response, does not have good, here crux is tuning rod and the preferably monoblock cast of strutbeam trestle, hardness between them, density, proportion are understood because of consistent like this, and it is pure to pronounce, and can't cast, can weld, outlying rural area does not have condition, can adopt the extrusion of African dialing spring box yet, but this method is too backward, and last resort should not be used.

Because aufbauprinciple is very simple, other is then needless to say among the figure.

Claims (1)

1, a class by single-ended fix the pronunciation inelastic musical instrument.
