[0046] Please refer to Figure 6 to Figure 13 As shown, an embodiment of the present invention further provides an automatic playing device, which includes a control system, and also includes the string pressing mechanism described in the above-mentioned first embodiment, and the control system is at least used to control the motor and the driving device. .

[0047] The plucking mechanism of the existing automatic playing device 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 several brackets with specific angles and lengths are realized, the structure is relatively complex, the bracket installation and positioning are difficult, and the purchase and maintenance costs are high. Tonal accuracy.

[0048] As another purpose of the present invention, in order to solve the technical problems of the above-mentioned plucki...

Abstract

The invention discloses a string pressing mechanism and an applied automatic playing device. The string pressing mechanism comprises a bracket body fixed relative to a musical instrument body, and further comprises a plurality of string pressing components arranged above the strings, each of the string pressing components It includes a motor and a first slide rail installed on the bracket body, a chord pressing module slidably arranged on the first slide rail, and a belt assembly driven by the motor. The belt assembly includes a belt and a pulley, and the first The slide rail and the belt are arranged parallel to the strings, the string pressing module is connected with the belt, the motor controls the belt to adjust the stroke of the string pressing module in the length direction of the strings, and each string pressing module The group includes a driving device, a module body, and a string pressing unit corresponding to the number of strings arranged on the module body, and the driving device is used to drive the string pressing unit to press the corresponding strings. The automatic playing device applies the string pressing mechanism. The invention saves the cost of production materials and reduces the difficulty of structural assembly.

Description

technical field [0001] The invention relates to a performance device, in particular to a string pressing mechanism and an automatic performance device using the same. Background technique [0002] Existing stringed instruments such as guitars or lutes are usually played by plucking and pressing the strings. With the development of machine intelligence and automation, robotics has gradually begun to be applied to the above stringed instruments in recent years. [0003] The existing string-pressing instrument robot provides a cylinder mounting base, and a string-pressing cylinder corresponding to each string of each fret of a stringed instrument such as a guitar is arranged on the cylinder mounting base, and a string-strike is arranged at the output end of the string-pressing cylinder. Pad, hitting or pressing the strings by the up and down movement of the string pressing cylinder. The above structure has the advantage of rapid response, but the disadvantage is also very obvi...
