detailed description

The utility model will be further described below in conjunction with specific embodiments and accompanying drawings.

As shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, it is a guitar structure embodiment one of the utility model that can be played automatically. Ordinary guitars can play wonderful melodies because of the combined effect of people's two hands plucking different strings and pressing the strings according to the score. The scheme adopted by the utility model is to adopt a mechanical fingering device and a mechanical string picking device to replace two hands of people. The solution of the first embodiment includes the neck 1 and the upper bridge 11 located at the head end of the neck 1, the resonance box 2 and the panel 21 forming the resonance box 2, and the lower bridge 12 located on the panel 21, which is fixed tightly on the upper piano. Six strings 3 between size 11 and bottom size 12. On the neck 1, on the top of the strings 3, that is, on the left side of the strings 3 shown in FIG. The upper end 43 of 4 is fixed on the head end of the neck 1, and the lower end 44 of the fingerboard 4 is fixed on the panel 21 of the resonance box 2. Have a plurality of strip-shaped through holes 13 on the neck 1, as shown in Figure 3, each described strip-shaped through-hole 13 is respectively positioned at the position between two frets on the fingerboard 4, on the neck 1 is provided with several mechanical fingering devices 5, wherein each strip-shaped through hole 13 is provided with a row of six mechanical fingering devices 5 respectively pointing to the six strings 3 between the fingerboard 4 and the neck 1. The mechanical fingering device 5 comprises a base 52, a telescopic finger 51, an electromagnet 53, and a rebound mechanism 54. The telescopic finger 51 runs through the base 52 and one end thereof is fixedly connected with the rebound mechanism 54. 53 reciprocates in the base 52 under the on/off state, and the stroke of the telescopic finger 51 can pass through the bar-shaped hole 13 to press the string 3 between two adjacent frets when stretched out. When the retractable fingers 51 are retracted, they can leave the strings 3 without touching the strings 3 . In this way, when the electromagnet 53 receives an electric signal, it will generate a magnetic force to push the telescopic finger 51 to generate a displacement, thereby passing through the strip-shaped through hole 13 to press the strings. When the electromagnet 53 cuts off the electric signal, the rebound mechanism 54 will generate a rebound force Drive telescopic finger 51 retraction and leave string; So some mechanical fingering devices fixed on the neck 1 are different because of the position, and the pitch that its telescopic finger presses string produces is different, just as staff presses string. On the top of the lower piano code 12, on the panel 21 of the resonance box 2, a mechanical string picking device 6 is fixedly arranged. 61 are all driven by a micromotor (not shown in the figure) by a speed reduction mechanism (not shown in the figure) by the gear 64 that is fixed on the picking wheel 61 and rotate around the fixed shaft 65; The signal works to drive the deceleration mechanism and the gear 64 and the string wheel 61 to rotate at a certain angle to realize the strings, as shown in Figure 5 and Figure 6; in this way, the six micro-motors receive different electrical signals and will drive the six strings. The string wheel implements different actions to pluck the strings, just like human hands plucking the strings. The mechanical picking device 6 is mounted on a fixed frame 7 , and the fixed frame 7 is fixedly mounted on the panel 21 of the resonance box 2 .

In this way, the existing technology of using a microcomputer to convert musical notes into electrical signals transmits different electrical signals to the mechanical fingering device through wires to achieve fingering pressing similar to that of a musician, and transmits different electrical signals to the mechanical picking device to achieve fingering. It is similar to the plucking of different strings of a musician to produce sound, thereby realizing the automatic performance of the guitar.

As shown in Figure 7, it is the second embodiment of the utility model. The second embodiment differs from the first embodiment in that the mechanical picking device 6 is located above the lower bridge 12 and below the panel 21 of the resonance box 2 . The through holes on the neck 1 are a plurality of circular through holes, and each telescopic finger corresponds to a circular through hole.

The above are only preferred embodiments of the utility model, and are not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included within the scope of the claims of the present utility model.
