Automatic playing device applied to plucked stringed musical instrument

Abstract

The invention discloses an automatic playing device applied to a plucked stringed musical instrument, which comprises a base fixed relative to a musical instrument body, a control system and a plucking mechanism controlled by the control system. The plucking mechanism is arranged on the base and comprises a plurality of plucking assemblies controlled by the control system; each plucking assembly is transversely arranged at a sound cavity of the musical instrument body, each plucking assembly comprises a steering engine arranged on the base, a connecting arm driven by the steering engine, a limiter relatively fixed with the musical instrument body and a plectrum arranged at the end part of the connecting arm, the connecting arm comprises a swing arm positioned at the tail section, the limiter is hinged with the swing arm, and the plectrum is arranged at the end part of the swing arm. The bottom end of the plectrum is close to the corresponding string, so that when the steering engine controls the connecting arm to swing, the swing arm is limited by the limiter to swing back and forth and drives the plectrum to move along a first track to pluck the string, and the first track comprises a pendulum track. The automatic playing device provided by the invention is convenient to assemble, and has the advantages of fast string plucking response and high precision.

Description

technical field [0001] The invention relates to a performance device, in particular to an automatic performance device applied to a plucked string instrument. Background technique [0002] Existing plucked stringed instruments such as guitar, erhu or pipa are usually played by plucking the strings. With the development of machine intelligence and automation, robot technology has gradually been applied to the above-mentioned plucked stringed instruments in recent years. [0003] The existing plucking instrument robot achieves the purpose of plucking strings by setting a corresponding plucking cylinder and bracket group at each string. When plucking a string, two plucking cylinders and several specific The angle and length of the bracket are realized, the structure is relatively complicated, the installation and positioning of the bracket are difficult, and the purchase and maintenance costs are high. At the same time, the use of cylinders for string picking has the disadvanta...

Problems solved by technology

[0004] In order to overcome the problems of relatively complicated structure of the existing automatic playing device, difficulty in installation and positioning of the bracket, and slow response speed of picking strings, an embodiment of the present invention provides an automatic playing device for plucked string instruments, including The fixed base also includes a control system and a string picking mechanism controlled by the control system, the string picking mechanism is arranged on the base, and the string picking mechanism also includes a plurality of string picking mechanisms controlled by the control system Each string assembly is arranged laterally at the sound chamber of the instrument body, and each string assembly includes a steering gear arranged on the base, a connecting arm driven by the steering gear, and a musical instrument. The relatively fixed limiter of the body and the paddle set at the end of the connecting arm, the connecting arm includes a swing arm at the end, the limiter is hinged with the swing arm, and the paddle is set at the end of the swing arm , the bottom end of the pick is close to the corresponding string, so that when the steering gear controls the swing of the connecting arm, the swing arm is limited by the limiter to swing back and forth, driving the pick along the first trajectory movement to pluck the strings, the first trajectory comprising a pendulum trajectory
