Abstract
The utility model discloses a kind of low Hu and resonant tank, comprise body and pull the bow, body is primarily of qin bar, resonant tank forms, qin bar lower end connects resonant tank, before resonant tank, vibration membrane is housed, draw and play on adjusting knob that string upper end is fixed on scroll head, lower end is fixed on bottom resonant tank by bridge, draw and play string jacking and be suspended on resonant tank vibration membrane, be provided with papery qin rete in described resonant tank, between vibration membrane and papery qin film, be provided with sound column, sound column one end jacking is on vibration membrane, and the other end is connected with papery qin film.Bow pulls string to vibrate vibration membrane by bridge, papery qin rete is transmitted to by sound column, produce synchro-resonance, amplify through resonant tank, volume doubles, this synchro-resonance mode, overcomes that vibration membrane vibration noise is large, the low toughness of papery qin film, shortcoming that volume is little, has played the advantage of papery qin film low-frequency vibration.Both combine, send sympathetic response have a low and deep voice, mellow and full, low Hu is had give great volume, the U.S. advantage of tonequality.
Description
Technical field:
The utility model relates to musical instrument, specifically refers to a kind of low Hu and resonant tank.
Background technology:
The low Hu of present use, resonant tank is made up of qin cylinder, vibration membrane, vibration membrane wraps in qin cylinder one end, vibration membrane is equipped with bridge, draw and play string jacking and be suspended on resonant tank epithelium, bow pulls string to be empathized by bridge vibration membrane, and this article qin has 2 deficiencies: 1, the sound noise that single vibration epithelium sends at resonant tank is large, lower tone; 2, bass during the sympathetic response sound sent lacks, volume is little.
The utility model object is to provide a kind of low Hu, and middle bass range scope can be expanded, and not only middle bass tonequality is good for the sympathetic response sound sent, noiseless, and gives great volume, bright melodious.Another object of the utility model is to provide a kind of resonant tank for low Hu.
The utility model object realizes like this, this low Hu, comprise body and pull the bow, body is primarily of qin bar, resonant tank forms, qin bar lower end connects resonant tank, before resonant tank, vibration membrane is housed, draw and play on adjusting knob that string upper end is fixed on scroll head, lower end is fixed on bottom resonant tank by bridge, draws to play string jacking and be suspended on resonant tank vibration membrane, papery qin film is provided with in described resonant tank, be provided with sound column between vibration membrane and papery qin film, sound column one end jacking is on vibration membrane, and the other end is connected with papery qin film.
Be provided with multilayer papery qin film in described resonant tank, be provided with sound column between vibration membrane with papery qin film and be connected, be provided with sound column between adjacent layer papery qin film and connect.
For a resonant tank for above-mentioned low Hu, comprise casing, before resonating body, be surrounded by vibration membrane, papery qin film is provided with in described resonant tank, be provided with sound column between vibration membrane and papery qin film, sound column one end jacking is on vibration membrane, and the other end is connected with papery qin film.
Owing to being provided with papery qin film in this low Hu Suoshu resonant tank, be provided with sound column between vibration membrane and papery qin film, sound column one end jacking is on vibration membrane, and the other end is connected with papery qin film.Bow pulls string to vibrate vibration membrane by bridge, vibration membrane vibration is transmitted to papery qin film by sound column, papery qin film is made to produce synchro-resonance, resonance sympathetic response sound amplifies through resonant tank, volume doubles, and this vibration membrane, papery qin film synchro-resonance mode, overcome the shortcoming that vibration membrane vibration noise is large, the low toughness of papery qin film, the shortcoming that volume is little, played the advantage of papery qin film low-frequency vibration.Both combine, and the sympathetic response sent has a low and deep voice, mellow and full, low Hu are had give great volume, the U.S. advantage of tonequality.

Embodiment:
This low Hu, comprise body and pull the bow, body is primarily of qin bar 12, resonant tank 4 forms, qin bar 12 lower end connects resonant tank 4, resonant tank 4 (qin cylinder) is equipped with vibration membrane 1 above, there is sound window 6 below, draw and play string 10 upper end and be fixed on the adjusting knob on scroll head, lower end is fixed on bottom resonant tank 4 by bridge 9, fingerboard is contained on qin bar 12, draw and play string 10 jacking and be suspended on resonant tank vibration membrane 1, papery qin film 5 is provided with in described resonant tank 4, sound column 8 is provided with between vibration membrane 1 and papery qin film 5, sound column one end 2 jacking is on vibration membrane, the sound column other end 7 is connected with papery qin film 5.Papery qin film 5 is by qin film frame 3 with screw or be adhesively fixed and fix in resonant tank 4 (qin cylinder), and sound column 8 is contained in the middle of papery qin film 5.Vibration membrane useful chemical epithelium, leather film etc. are made.
Be provided with multilayer papery qin film 5 in described resonant tank 4, be provided with sound column 8 and be connected between vibration membrane 1 with papery qin film 5, be also provided with sound column 8 between adjacent layer papery qin film 5 and connect, sound column 8 has conducted vibration, makes multilayer papery qin film 5 produce synchro-resonance.
Be provided with sound column 8 synchro-resonance structure between vibration membrane 1 and papery qin film 5 in the utility model resonant tank, also can be widely used on the percussion instrument of the national musical instruments such as urheen, leather Hu and drum class.
