[0046] Please refer to Figure 6 to Figure 13 As shown, the embodiment of the present invention also provides an automatic playing device, including a control system, and also includes the string pressing mechanism described in the first embodiment above, 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 the strings by setting a corresponding plucking cylinder and bracket group at each string. When plucking a string, two plucking cylinders that cooperate with each other are usually required. And some brackets with specific angles and lengths are realized. The structure is relatively complicated, the installation and positioning of the brackets are difficult, and the purchase and maintenance costs are high. pitch accuracy.

[0059] As an improvement to the strumming mechanism of the second embodiment above, in this embodiment, a first lifting mechanism is also provided between the "I"-shaped fixing frame and the steering gear mounting seat, and the "" Each horizontal bracket of the "glyph limiter is provided with a second lifting mechanism on both sides of the vertical bracket. The first lifting mechanism is used to raise or lower the height of the steering gear, and the second lifting mechanism is used to raise or lower the horizontal The height of one or both sides of the stand to change the height of the picks. Exemplarily, when the control system controls the first lifting mechanism below the steering gear mounting seat of any pizzicato assembly to rise, at the same time controls the second elevating mechanism on the side of the transverse bracket corresponding to the pizzicato assembly to rise, so as to lift the corresponding The height of the plectrum of the plucked string assembly reduces t...

Abstract

The invention discloses a string pressing mechanism and an automatic playing device using the same. The string pressing mechanism comprises a support body which is fixed relative to a musical instrument body, and also comprises a plurality of string pressing assemblies disposed above strings. Each string pressing assembly comprises a motor, a first sliding rail, a string pressing module and a beltassembly, the motor and the first sliding rail are installed on the support body, the string pressing module is arranged on the first sliding rail in a sliding mode, the belt assembly is driven by the motor and comprises a belt and a pulley, the first sliding rail and the belt are parallel to strings, and the string pressing module is connected with the belt. The motor controls the belt to adjustthe stroke of the string pressing modules in the length direction of the strings, each string pressing module comprises a driving device, a module body and string pressing units arranged on the module body, the number of the string pressing units corresponds to the number of the strings, and the driving devices are used for driving the string pressing units to press the corresponding strings. Theautomatic playing device applies the string pressing mechanism. The production material cost is saved, and the structural assembly difficulty is reduced.

Description

technical field [0001] The invention relates to a playing device, in particular to a string pressing mechanism and an automatic playing 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, robot technology has gradually begun to be applied to the above-mentioned 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 set on the cylinder mounting base, and the string-pressing cylinder is set at the output end of the string-pressing cylinder. The pads are used to strike or press the strings by the up and down motion of the string pressing cylinder. The above-mentioned structure has the advantage of quick response, but t...
