Abstract
A kind of noiseless matouqin, be characterized in, noiseless matouqin has a scroll head, scroll head connects fingerboard, fingerboard connects qin case, scroll head installs two pegs, boom plate installed by qin case, boom plate hangs with two strings, two strings are respectively stretched in before fingerboard in a peg, in qin case, elastic plate and sensor holder are installed, elasticity installs bridge before pole, two strings are pressed in bridge, after elastic plate, contact is installed, sensor installation on sensor holder, contact pressure on a sensor, mounting circuit boards in qin case, sensor is connected with circuit board by wire, in qin case, battery is installed, battery is connected with circuit board by wire, mounting receptacle on circuit board, socket is inserted with plug, plug is by wire frames connecting with headphone, string reclines bow.The utility model is used for beginner's exercise, and this noiseless matouqin is changed by acoustic-electric, and practitioner is by headphone monitor playing effect, and the external world can't hear the sound drawing qin, thus avoids the generation of the phenomenon that disturbs residents.
Description
Technical field
The utility model relates to a kind of national musical instruments, and especially a kind of only have practitioner to hear when practising and the external world can't hear the noiseless matouqin of sound.
Background technology
Matouqin is widely current in the pastoral area of Inner Mongolia Autonomous Region and farming-pastoral region, is also used by many professionals.The sound of matouqin is melodious soft and graceful, and during performance, sound is very interesting to listen to.But beginner is when practising, and monotony, even sometimes occurs hoarse sound, thus become neighbourhood noise, even produce the phenomenon that disturbs residents.
Summary of the invention
For solving the above problems, the utility model provides a kind of noiseless matouqin, and this noiseless matouqin is changed by acoustic-electric, and practitioner is by headphone monitor playing effect, and the external world can't hear the sound drawing qin.
The technical scheme that the utility model technical solution problem adopts is: invent a kind of noiseless matouqin, be characterized in, noiseless matouqin has a scroll head, scroll head connects fingerboard, fingerboard connects qin case, scroll head installs two pegs, boom plate installed by qin case, boom plate hangs with two strings, two strings are respectively stretched in before fingerboard in a peg, , in qin case, elastic plate and sensor holder are installed, before elastic plate, bridge is installed, two strings are pressed in bridge, after elastic plate, contact is installed, sensor installation on sensor holder, contact pressure on a sensor, mounting circuit boards in qin case, sensor is connected with circuit board by wire, in qin case, battery is installed, battery is connected with circuit board by wire, mounting receptacle on circuit board, socket is inserted with plug, plug is by wire frames connecting with headphone, string reclines bow.
The beneficial effects of the utility model are, the utility model is used for beginner's exercise, and this noiseless matouqin is changed by acoustic-electric, and practitioner is by headphone monitor playing effect, and the external world can't hear the sound drawing qin, thus avoid neighbourhood noise and the generation of the phenomenon that disturbs residents.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Accompanying drawing 1 is the front view of the present embodiment, and accompanying drawing 2 is left views of the present embodiment.
1 scroll head in figure, 2 pegs, 3 fingerboards, 4 earphones, 5 bows, 6 strings, 7 qin casees, 8 bridges, 9 boom plates, 10 plugs, 11 batteries, 12 sockets, 13 circuit boards, 14 sensor holders, 15 sensors, 16 contacts, 17 elastic plates.
Embodiment
As shown in Figures 1 and 2, scroll head 1 connects fingerboard 3, fingerboard 3 connects qin case 7, scroll head 1 installs two pegs 2, qin case 7 is installed boom plate 9, boom plate 9 hangs with two strings 6, two strings 6 are each to be stretched in before fingerboard 3 in a peg 2, , in qin case 7, elastic plate 17 and sensor holder 14 are installed, elastic plate 17 installs bridge 8 above, two strings 6 are pressed in bridge 8, elastic plate 17 installs contact 16 below, sensor installation 15 on sensor holder 14, contact 16 is pressed on sensor 15, mounting circuit boards 13 in qin case 7, sensor 15 is connected with circuit board 13 by wire, in qin case 7, battery 11 is installed, battery 11 is connected with circuit board 13 by wire, mounting receptacle 12 on circuit board 13, socket 12 is inserted with plug 10, plug 10 is by wire frames connecting with headphone 4, string 6 reclines bow 5.
Matouqin playing method with traditional during exercise is identical, earphone 4 is worn on ear by practitioner, pull bow 5, bow 5 and string 6 rub, string 6 produces vibration, string 6 by vibration passing to bridge 8, bridge 8 vibration passing is to elastic plate 17, elastic plate 17 and bridge 8, string 6 forms vibrational system jointly, elastic plate 17 has the effect to vibration mode shaping, elastic plate 17 by the contact 16 at rear portion by vibration passing to sensor 15, vibration is changed into electric signal by sensor 15, electric signal is delivered to circuit board 13 by wire, after electric signal shaping is amplified by circuit board 13, through socket 12, plug 10 and wire are delivered to earphone 4, transform electrical signals is become sound by earphone 4, make practitioner can monitor the effect of oneself drawing qin.Because the surface area of string 6, bridge 8 and elastic plate 17 is all less, the sound produced when vibrating is very faint, and the external world almost can't hear the sound drawing qin, thus avoids neighbourhood noise and the generation of the phenomenon that disturbs residents.
