Abstract
The utility model discloses a sound amplifying resonance device, wherein a string sheet 4 is tightly fixed on a support table 8 by a steel plate spring 5, one end of a musical capo 2 is abutted on a musical plate 1, the other end of the musical capo 2 is fixed on the string sheet 4 and a resonance sheet 3 is connected to middle of the musical capo 2. The utility model has the advantages of easy taking of materials, abundant resources, low cost, little possibility of being damaged and small size, and has sufficient volume and beautiful tone color; boa skin can be completely replaced, large-scale industrialized manufacture can be realized.
Description
Affiliated technical field
The present invention relates to a kind of is the sound amplification sympathetic response device of source of sound with the string.
Technical background
The musical instrument that with the string is source of sound comprises bowed instrument, hammered string instrument and plucked string instrument.String is very desirable sounding body, when the fixing string in two ends vibrates, and originally whole string synchronous vibration, the sound that sends is called fundamental tone.After the whole string synchronous vibration, vibration wave transmits along tangential two ends, and in the end points reflection that is hampered, two row reflection waves can meet at the mid point of string.Because this two row reflection wave equal and opposite in direction, direction are opposite, so the mid point of string will transfixion, this is called standing wave phenomena on physics, and actionless point is called standing wave node.Standing wave node is called the overtone point in music.Owing to the mid point transfixion that two row reflection waves meet and make string at the mid point of string, the vibration of string at this moment just is divided into two sections to be carried out, the vibration frequency height one times, the sound that sends is called overtone.Can infer, the transmission of the vibration wave of string and reflection also can continue, and can produce more standing wave node and overtone.The vibration frequency of these overtones is doubled and redoubled, be called first overtone, second overtone, the 3rd overtone ... " general " has many meanings, the meaning of " overtone " is exactly an additional sound on the basis of fundamental tone, and these " additional sounds " can make the string sound rich and varied, magnificent interesting to listen to.
Because string is thinner, the energy of its vibration is very little, must amplify the sympathetic response device with sound and amplify.Sound amplifies the sympathetic response device and is broadly divided into two kinds of forms: the box and covering type of sympathetic response, the former is as Zheng, violin, guitar etc., the latter such as trichord, urheen etc.The box sympathetic response device of sympathetic response is actually a watertight aircase, and the natural vibration frequency of this watertight aircase and the natural frequency of string are close, and string vibration just the causing sympathetic response of watertight aircase is resonated in other words.Sound reflects to form echo back and forth in casing simultaneously, after string stops vibration, can also hear that casing is continuing pronunciation.This phenomenon is in the big musical instrument of resonant tank, as more obvious on violoncello, the contrabass.
The covering type sympathetic response then is to utilize the animal skins of tightening to realize.The animal skins of tightening is very responsive to vibration, and just beaing gently can be sent very big sound, can understand this phenomenon from the small drum in Xinjiang.A slight qin tube is coverd with the boa skin and also can be obtained very big sound equipment, and its whole secrets are just on that piece boa skin.Boa leatherware after tightening has extraordinary elasticity, and more more responsive than other animal skins to vibration, very little power just can it be vibrated, and very big amplitude is arranged.The boa skin is very thin, yet very tough and tensile, is very rare pronunciation material.This performance of boa skin is that the life habit of boa uniqueness brings up, boa realizes creeping by the twisting health, for hunting and escaping danger, it must twist health in fast and flexible ground, this just requires its skin must be very thin, and simultaneously, long-term creeps, through tempering of jungle gravel, it is very tough and tensile that its skin becomes again.Be subjected to the protection of law because boa has belonged to animals on the brink of extinction today, makes us must abandon using the boa skin.The research that replaces the boa skin in recent years is many, replaces the boa skin as metal skin, but this simple substituting certainly will be caused volume deficiency, problem that tone color is not good enough.
Summary of the invention
The purpose of this utility model provides that a kind of rich material resources, cost are low, long service life, echo effect is arranged, sound with enough volumes and fine tone color amplifies the sympathetic response device.Simultaneously, use the utility model little, guaranteed the playing technique and the song of original musical instrument existing musical instrument general structure and profile change.
The technical scheme that its technical matters that solves the utility model adopts is: string sheet 4 is tightened by leaf spring 5 and is fixed on the supporting station 8, and leaf spring 5 withstands on the support plate 6.Sound column 2 one ends head on soundboard 1, and the other end is fixed on the string sheet 4, and resonance plate 3 is connected the centre of sound column 2.Resonance plate 3 is no less than 1.Soundboard 1 is the sheet metal of 500-650 degree annealing.Soundboard 1 is tabular or corrugated.
The beneficial effects of the utility model are: draw materials conveniently, and aboundresources, cost is low, and not fragile, volume is little, has enough volumes and fine tone color, can substitute the boa skin fully, and can realize large-scale industrial production.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a partial structurtes synoptic diagram of the present utility model.
Among the figure: 1. soundboard, 2. sound column, 3. resonance plate, 4. string sheet, 5. leaf spring, 6. support plate, 7. screw, 8. supporting station.
Embodiment
Leaf spring 5 has been tightened string sheet 4, has formed one and has drawn a bow, and string sheet 4 is equivalent to bowstring.When string drove soundboard 1 vibration, soundboard 1 can vibrate on string sheet 4 by compressing sound column 2.Because 4 pairs of vibrations of string sheet are very responsive, very little power just can make it vibration, and this just makes soundboard 1 can drive sound column 2 vibrations very like a cork.The vibration of sound column 2 can drive resonance plate 3 again and vibrate together, and the vibration of resonance plate 3 feeds back to soundboard 1 by sound column 2 again, produces the general effect of echo, has strengthened sympathetic response, has beautified tone color.
