V. New description: [New technical field] This creation is about plucking devices, especially those that can be driven by a mechanical structure to emit a string-like sound. [Prior Art] According to the known, the anthropomorphic performance device is different from the general electronic synthetic instrument tape, CD, DVD MP3, and player. It is a real instrument using a traditional guitar, piano, drum, and the like. The main body uses a performance device, such as an electromechanical device, to generate a plucking string, a thief tapping, and the like, so that the music is rotated, thereby achieving a live effect such as live performance; and the anthropomorphic performance device has the advantage of playing Music, 100% of the instrument's original sound 'not like the synthetic sound produced by the electronic device makes people feel "false", in addition, the anthropomorphic performance | except for the presence of the performance: the performance of the performance device itself is full of fun, but also In Lin, a good atmosphere is created, which is unmatched by CD, DVD, and _ electronic playback devices. Moreover, since most of the humanized performance devices can be played automatically, they can be pre-loaded by fine The music of the person and the age, and the automatic performance of the performance through the electrogram performance device without being affected by human factors, and Lin Chang _ performance, which is live live performance Unable to reach advantage. It is known that the anthropomorphic performance device of the traditional stringed instrument mainly uses a set of pneumatic plucking devices to make the instrument produce a sound. The part of the bribe string mechanism is to take care of the plucked copper fishing, and use the copper hook to hook or release the string. The operation is to produce the effect of plucking the string; and the actuated plucking device is not only complicated in structure, large in volume, but also requires fine air pumping wire during the operation of the M378468 (4) force _, noise generated during the operation of the ridge green It often interferes with the performance of the instrument. In addition, the _actuated copper fishing is slower in the reverse displacement, so there is often a situation in which the beat of the melody can not keep up with the beat. [New content] The author of this creation provides a kind of _ device, which is a set of programmable stepping motors (Step Mot (8) as the age operation _ force source, to read the rate of plucking operation of the plucking string] to meet the performance requirements of the (four) beat music. Moreover, it has the advantages of machine-single, small size and low cost, which can improve the unfavorable characteristics of the conventional gas transmission string device. According to the present creation, the plucking device mainly comprises a base, a turning drive, and a a string arrangement; wherein the base is provided with a fixing member such as a screw or a clamp, etc., so that the base can be fixed on the instrument body and adjacent to a position near the string; the swing driver is mounted on the base And having a drive shaft extending to the plucking position; the chord is attached to the drive shaft and has an elastic chord contact edge; by controlling the steering, rotation angle and rotational speed of the drive shaft of the yaw drive, To manipulate the string to dial the string of the instrument to produce the sound. In particular, the swing driver is selected from a programmable stepper motor or a pulse motor (Pulse Motor), etc. of The circumference is not limited to the aforementioned components. In particular, the stringing mechanism of the pivoting shaft on the driving shaft is disposed between the two strings of the musical instrument, so that the string dial can freely dial any one of the two strings. It is 'the string is elastic sheet, and its string contact edge is pointed, ore or scalloped, oval, melon or teardrop. In particular, the material of the string is selected from plastic, Metal, metal alloy, glass fiber, etc., but the material range of the implementation is not limited to the above materials. In particular, it further includes a creel that can be fixed on the instrument body and can be coupled with the end of the aforementioned transmission shaft to gain The stability of the drive shaft. This will further clarify the other functions and technical features of this creation, which can be realized by the skilled person after reading the description in the text. [Embodiment] The plucking device of the present invention is arranged on a guitar string set. A preferred embodiment is used. The base 2 of the plucking device is fixed on the body of the guitar 1 and spans the guitar string group. Above' and there is a complex array on the base 2 The swivel drive 3 'here, the swivel drive 3 is a stepper motor that is small in size and high in torque output and programmable, so that the stepping motor can be controlled by a pre-programmed pulse signal. Steering, cornering, and rotating speed operation, and the turning actuators 3 each have a driving shaft 31 extending along the guitar string 12 and positioning the driving shaft just between the strings 12; The 4 series is pivoted to the drive shaft 31, and the chord contact edge 41 at the end of the chord 4 is just in contact with the chord 12 on both sides, so that it can be rotated or swung together with the drive shaft to toggle the two sides. a string, and the end of the string 4 is a flexible sheet configuration, and a material such as Celluloid material can be selected, and the string contact edge 41 at the end of the string is in the shape of a melon to ensure the string The pitch characteristics. 5 When operating according to the component structure, the stepping motor of the swinging drive g 3 is operated by a pre-programmed program, and the rotation of the stepping motor is rotated or oscillated, for example, using the stepping motor to sigh (four) The characteristics of the high torque output enable the recording 4 to correctly oscillate the angle (orphan) to pluck the string to emit a specific sound. The stepping motor can be used to control the positive and negative rotations, so it is placed in the middle of the chord line 12. The string dial 4 can balance the operation of the two-string line, so that the assembly components of the dialing device can be simplified, and the installation cost can be saved. In addition, the function of the flapping speed of the stepping motor can also be utilized to The speed of the string can accurately play the beat of the music, and the speed of the chord can be controlled by the motor to avoid the sound of the plucking string, so that the music line produces a small sound (ie, the sound size). ). Further, as in the second embodiment of FIG. 4, the general structure and operation mode of the plucking device are the same as those of the first-real one, and the main structural difference is that a set of pedestal 5' is also provided. Above the guitar string set and fixed on the body of the guitar i, and the shaft frame 5 is provided with a shaft hole 51 to be axially coupled with the end of the transmission shaft 31, thereby improving the stability of the transmission shaft and the string structure. Sex. The present invention is not limited to the above-described forms, and it is obvious that with reference to the above description, there can be more improvements and variations in technical equivalence, such as: the material of the aforementioned string 4 and the shape and thickness of the string contact edge 41 at the end thereof. The selection can be determined according to the characteristic sounds that the plucking operation is intended to be. The plastic chord is suitable for nylon strings. The metal chord is very hard and rigid. It is more suitable for metal strings. Differences in degree characteristics can be used to produce different tones and sound quality;
