Description

Wipe the string device

Technical field

The utility model relates to a kind of wiping string device, is meant especially a kind ofly to wipe the strings of musical instruments and produce the wiping string device of sound equipment.

Background technology

Bowed stringed instrument, bowed stringeds instrument such as urheen, matouqin, violin and violoncello particularly, its sounding principle is to use bow hair friction string on the bow and sounding, the player will bend with string puts and meets at right angles, make the string vibration with suitable speed and pressure pulling string again, and, amplitude can be changed and volume is changed, thereby bring up beautiful melodious and changeable string music sound by speed or pressure that change is pulled the bow; The tonequality of this string music and tone color change mysterious, and to play the impression of giving the people live outstanding dark with shock listening to, and the electronic music that general absolutely not electronics synthesized instrument, audiotape, CD, DVD MP3 player are provided can be compared.

Yet want the wonderful live play of music appreciating man often to be subjected to the restriction of multiple external factors such as economy, space-time, so produced the various music performance apparatus that personalize; And the music performance apparatus that generally personalizes is to use real instrument bodies such as traditional guitar, piano, drum to pass through music performance apparatus, electro-mechanical device for example, produce effects such as wiping string, manipulate the strings or knock, make musical instrument send the sound, to reach the Presence of playing live as true man.

The advantage of the above-mentioned music performance apparatus that personalizes is that the music of playing out is the former sound of hundred-percent musical instrument, therefore the telepresenc that has performance, and itself promptly is full of enjoyment the music performance apparatus operation, also can build good entertainment atmosphere at the scene, moreover, but music performance apparatus mostly is the robotization performance greatly because this class personalizes, it can import and store music score in advance by computing machine, and can not be subjected to the human factor influence by automatic continuous performance of computer control music performance apparatus, and can play for a long time, this is again that the advantage that is beyond one's reach is drilled at the true man scene.The music performance apparatus that personalizes of at present known bowed stringed instrument mainly is to utilize a set reciprocating mechanism to drive bow to do front and back or side-to-side movement, makes the bow hair friction string on the bow and sends music; Yet, this bow that drives by reciprocating mechanism is during the stroke latter end of, reciprocating cutter and conversion direction of motion, because the relation of mechanical component motional inertia can cause the state that the string running is stagnated of wiping, especially can't produce fully especially at the dead point of movement travel (dead point) and wipe the string sound equipment, this result will cause music rhythm to take off bat, the error of melody accuracy in pitch, even play discontinuous disappearance.

The utility model content

Fundamental purpose of the present utility model is to provide a kind of wiping string device, to control this wiping string device freely and then to produce the high-quality playing effect that personalizes.

The disclosed wiping string of the utility model device comprises:

One belt wheel group is arranged on this pedestal, and comprises a driving wheel and a follower at least;

One wipes the string band, is set around between the driving wheel and follower of aforementioned belt wheel group;

One rotary drive assembly is used to drive the driving wheel rotation of this belt wheel group;

Above-mentioned follower is located on the slide, and the guide rail setting of the corresponding said base of this slide also articulates a displacement drive assembly, and this displacement drive assembly is used to drive described slide along described guide rail slippage, and then drives the string of a musical instrument of described wiping string band friction bowed stringed instrument.

Above-mentioned wiping string device, continuous and stable good wiping string running can be provided, and can wipe the friction velocity of string device and string or pressure with the sound equipment of generation different frequency and amplitude by regulation and control, bring up beautiful changeable string music sound, and have the advantage that mechanism is simple, volume is little and with low cost.

Particularly, this wiping string band is to be placed through between two strings of a musical instrument of this musical instrument; This wiping string band is a fiber harness, and its fiber material is selected from Baima dodds, unexpected rival's dodds or polyamide (Polyamide) ... Deng, but the material ranges of implementing is not exceeded with previous materials.

Particularly, this rotary drive assembly is an electro-motor; This rotary drive assembly can be selected program-controlled step motor (Step Motor) or pulse wave motor (Pulse Motor) for use, with the rotating speed of regulating and control this belt wheel group and this wiping string band or turn to, changes frequency or the amplitude of wiping the string sound equipment.

Particularly, this displacement drive assembly is selected from solenoid valve, cylinder, oil hydraulic cylinder or by screw rod (worm screw) gear train of step motor control etc., but the scope of implementing is not exceeded with the aforementioned displacements driven unit.

Particularly, this displacement drive assembly is a closed type or open type direct-acting electromagnetic valve.

Particularly, this belt wheel group more comprises tension adjustment wheel, can be in order to regulate and control the tension force of this wiping string band.
