New description: [New technical field] This creation is about a kind of string-scissing device, especially a kind of string-scissing device that can sing the strings of an instrument to produce sound. [Prior Art] According to the 'bow-stringed instrument', especially the bowed string instruments such as a Hu, Ma Tauqin, violin and cello, the principle of sound is to use the bow hair on the bow to rub the strings and make a sound. The ## will put the bow and string into At right angles, the strings are pulled at the appropriate speed and pressure to vibrate the strings. By changing the speed or pressure of the bow, the amplitude can be changed to change the volume, resulting in a beautiful and melodious string sound; The sound quality and the change of the sound of the strings are mysterious. The feelings and shocks of listening to the live performances are especially deep, which is not comparable to the electronic music provided by general electronic synthetic instruments, tapes, CDs, DVD MP3 players; however In order to appreciate the musician's exquisite live performance, in addition to the cost of the time, it will be limited by many external factors such as time and space. Yu Yu has appealed to various anthropomorphic performance devices to be created; and the general anthropomorphic performance device is Using a real musical instrument body such as a guitar, a piano, a drum, or the like, by means of a performance device, such as an electromechanical device, generating a _, a dialing, etc. Sounds, according to which to achieve the live performance of the live field _ field effect; the advantage of this anthropomorphic performance device is that the music played is 100% of the original sound of the instrument, so the performance of the performance is very impressive. For fun, the village Wei field creates a good atmosphere. Moreover, since most of these anthropomorphic performances can be played automatically, they can be pre-entered and stored by a computer and automatically played continuously through a computer controlled performance 3 device. It is not affected by human factors and can be played for a long time, which is an advantage that cannot be achieved by live performances. The anthropomorphic performance device of the currently known bowed string instrument mainly uses a set of reciprocating mechanisms to drive the bow for front and rear or left and right movement, thereby causing the bow on the bow to rub the strings and make a sound; however, the levee borrows The bow driven by the reciprocating mechanism during the end of the stroke of the forward and complex movements and the direction of the change of motion, due to the inertia of the mechanical components, will cause the squeaking operation to stagnate, especially at the dead point of the motion stroke. It is completely impossible to produce a string sound, which will result in the beat of the music, the melody pitch error, or even the lack of continuous play. [New content] Therefore, the main purpose of the present invention is to provide an improved squealing device which can provide continuous and stable squeegee operation, and can control the friction or pressure of the chord device and the string.

Wherein, the motor 5 is selected to be small in size and high in torque, and is programmable to be a stepping motor. Therefore, the pre-programmed pulse signal can be used to control the steering and speed operation of the stepping motor; Paste 6 uses a normally open type direct acting solenoid valve. According to the foregoing components, the programmable stepping motor 5 is controlled by a program programmed by the county to drive the driving wheel 2 to drive the cleaning band ring 4 and the driven wheel 3 to rotate, so that the outer side of the ring string 4 is rotated. Rubbing the first string % of the instrument to produce a string sound; in addition, the coil of the normally open type direct-acting solenoid valve 5 (not shown) can be energized to generate electromagnetic force, so that the contact 61 62 is close to the static iron and is not shown in the drawing. The solenoid valve 5 is in a closed valve state, and the movable iron core 61 makes the sliding seat 7 and the passive wheel 3, and the cleaning string ring 4 is inside. The second string 92 of the side frictional instrument produces another type of sound, and then the electromagnetic force disappears when the power is off. The dynamic state of the spring 62 is restored to the position of the spring 62. The moving iron core 61 resets the sliding seat 7 and the driven wheel 3, and the cleaning stringing ring 4 generates a stringing sound by the first string 91 of the outer frictional instrument so that the string cleaning device is between the two strings 91 and 92. Selectively rubbing the string to operate; 曰 In addition, M378467 also uses the programmable characteristics of the stepper motor 5, _ control the speed or steering of the rubbing band ring 4 Variable wiping operation state of the string, the string data to adjust the wipe bass sound (i.e., frequency) and / or the size of the sound (i.e., amplitude). Referring to the second embodiment of the fourth embodiment, the tension adjusting wheel 8' is added to the structure of the foregoing embodiment to make the rim of the adjusting wheel 8 and the sling band ring* roll-fit; The adjustment _ 8 is pivoted to the group-displaceable profile 8 and the slider phantom can be adjusted by the screw drive mechanism (or the blade drive mechanism) 82, and the position of the adjustment wheel 8 can be adjusted by using the adjustment_ The tension of the string winding ring 4 is adjusted, thereby ensuring that the winding of the string winding ring 4 and the string cleaning operation are normal. In summary, the creation of the string cleaning device has the advantages of simple mechanism, small size and low cost, and it has many breakthrough effects, for example: the creation can be through the overtones. Speed or steering, to change the fresh or vibration of the string sound, the paving sound f, and create a rich rhythm; and the county belt ring can provide continuous and awkward silk operation, to create a smooth flow County audio, avoiding the rhythm age, melody pitch error or playing discontinuity = Missing 'other' The continuous string rubbing operation of the rubbing string loop can produce an infinite sustain (SUS (four) effect, showing a new performance technique, breaking through the tradition Performance restrictions. This creation is not in the above-mentioned form. It is very dependent on the above explanations that there can be more technical improvements and changes. Therefore, any modification of this creation made under the spirit of marriage creation Or the changes should still be included in the scope of this creative intent.
