An automatic playing device applied to plucked stringed instruments

Abstract

The invention discloses an automatic playing device applied to a plucked stringed musical instrument, comprising a base relatively fixed with the instrument body, a control system and a plucking mechanism controlled by the control system. The plucking mechanism is arranged on the base, and the plucking mechanism The mechanism also includes a plurality of plucking components controlled by the control system, each plucking component is laterally arranged at the sound cavity of the instrument body, and each plucking component includes a steering gear set on the base, a connecting arm driven by the steering gear, A limiter relatively fixed to the instrument body and a pick set at the end of the connecting arm, the connecting arm includes a swing arm located at the end section, the limiter is hinged with the swing arm, the pick is arranged at the end of the swing arm, and the bottom of the pick The end is close to the corresponding strings, so that when the steering gear controls the swing of the connecting arm, the swing arm limiter restricts the reciprocating swing, and drives the pick piece to move along the first track to pick the string, and the first track includes the pendulum track. The automatic playing device of the present invention is easy to assemble, and has the advantages of quick response to plucking and high precision.

Description

technical field [0001] The present invention relates to a performance device, in particular to an automatic performance device applied to a plucked stringed musical instrument. Background technique [0002] Existing plucked 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 begun to be applied to the above plucked instruments in recent years. [0003] The existing plucked instrument robot achieves the purpose of plucking by arranging a corresponding plucking cylinder and a bracket group at each string. When plucking a string, it is usually necessary to cooperate with two plucking cylinders and a number of specific plucking cylinders. The angle and length of the bracket are realized, the structure is relatively complex, the bracket installation and positioning are difficult, and the purchase and maintenance costs are high. At the same time, the use of ...

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
