Description
Technical field
A kind of string device that draws relates to the parts of musical instrument.
Background technology
Traditional stringed musical instrument only back and forth spurs on string with bow and plays.Form is single, is not easy to musical instrument is transformed.
The utility model content
This practical purpose provides a kind of mode of rolling friction of utilizing and carries out the device that string music is played.
Originally draw the string device by power part, control assembly and draw the string parts to constitute; Power part comprises belt, belt pulley; Control assembly comprises backguy, spring, lever, swing arm, support; Draw the string parts to comprise axle, transmission of power wheel, friction wheel; Belt is contained on the belt pulley, and belt passes the middle part of support, and walks around the top of support; Swing arm is contained on the support through hinge axis, and lever links to each other with swing arm, backguy pass support above, link to each other with the outer end of lever, spring is contained between lever and support, and backguy is placed in one; The two ends of axle are equipped with transmission of power wheel and friction wheel respectively, and axle passes swing arm, and by bearings, the transmission of power wheel is positioned at the belt below, and friction wheel is positioned at the top of string.
Originally draw the working method of string device to be: belt pulley rotates provides power.Upwards backguy, pull lever drives swing arm deflection, and while axle, transmission of power wheel and also deflection thereupon of friction wheel above that makes the transmission of power wheel contact with the belt of its top, and rotates.The transmission of power wheel drives axle and friction wheel rotates.Friction wheel contacts through the mutual string of deflection, and friction with it, produces the effect that bow draws string.Originally draw the string device to be fit to be contained on the keyboard instrument with the string sounding,,, enrich its playing mode so that it is transformed like piano.
