[0029] Embodiment 1
[0030] like Figure 1-4 An automatic playing device shown in the figure comprises: a fixing base 1; a driving motor 11, a first striking assembly 2, a second striking assembly 3, a third striking assembly 4 and a fourth striking assembly 5 are fixedly arranged on the fixing base 1; a rotating shaft 12 is also rotatably arranged on the fixing base 1; the rotating shaft 12 is transmission-connected with the driving end of the driving motor 11; a first cam which can abut against the control end of the first striking assembly 2, a second cam which can abut against the control end of the second striking assembly 3, a third cam which can abut against the third striking assembly 4 and a fourth cam which can abut against the fourth striking assembly 5 are fixedly arranged on the rotating shaft 12.
[0031] Specifically, in the present application, the driving motor 11 is used to control the playing speed. The driving end of the driving motor 11 is connected to the rotating shaft 12. Each time the rotating shaft 12 rotates one circle, one measure of music can be played. By controlling the rotation speed of the driving motor 11, the playing speed of the striking assembly can be controlled accordingly. The driving motor 11 drives the cam to rotate, and the cam can push the striking assembly upward. When the cam rotates to other positions, the striking assembly falls, and the percussion instrument can be struck. By specifically setting the shape of the cam, the striking assembly above can be controlled to complete the corresponding striking action.
[0032] In summary, the present application proposes an automatic performance device, which can play a specific percussion score by controlling the rotation speed of the rotating motor, and can play different scores by adjusting the shape of the cam on the rotating shaft 12. Compared with the existing mechanical music box, it has a wider performance capability. The driving motor 11 can also be electrically connected to other control components to make the performance speed of the device cooperate with other musical instruments.

[0034] Furthermore, the first striking assembly 2 includes a first base 21 and a first connecting seat 22; the first base 21 is fixedly connected to the fixed seat 1, and the first connecting seat 22 is rotatably connected to the first base 21; a first top column 23 that can abut against the first cam is slidably provided on the first base 21; the top end of the first top column 23 abuts against the first connecting seat 22; a first drumstick 24 for striking the closed cymbals is also fixedly provided on the first connecting seat 22.
[0035] Furthermore, the second striking assembly 3 includes a second base 31 and a second connecting base 32; the second base 31 is fixedly connected to the fixed base 1, and the second connecting base 32 is rotatably connected to the second base 31; a second top column 33 that can abut against the second cam is slidably provided on the second base 31; the top end of the second top column 33 abuts against the second connecting base 32; and a first pedal 34 for striking the bass drum is also fixedly provided on the second connecting base 32.
[0036] Furthermore, the third striking assembly 4 includes a third base 41 and a third connecting base 42; the third base 41 is fixedly connected to the fixed base 1, and the third connecting base 42 is rotatably connected to the third base 41; a third top column 43 that can abut against a third cam is slidably provided on the third base 41; the top end of the third top column 43 abuts against the third connecting base 42; a second pedal 44 for striking a spare bass drum or a spare cymbal is also fixedly provided on the third connecting base 42.
[0037] Furthermore, the fourth striking assembly 5 includes a fourth base 51 and a fourth connecting seat 52; the fourth base 51 is fixedly connected to the fixed seat 1, and the fourth connecting seat 52 is rotatably connected to the fourth base 51; a fourth top column 53 that can abut against a fourth cam is slidably provided on the fourth base 51; the top end of the fourth top column 53 abuts against the fourth connecting seat 52; a second drumstick 54 for striking the snare drum is also fixedly provided on the fourth connecting seat 52.
[0038] Specifically, in the present application, the first striking assembly is used to strike the cymbals to achieve the sound of "times". Four abutment blocks are evenly arranged on the first cam, so that the sound of "times, times, times" can be emitted when the first cam rotates one circle. The second striking assembly is used to strike the bass drum, and the bass drum is struck by stepping on the pedal. Therefore, the second striking assembly is provided with a second pedal 44, and the second cam is provided with an abutment block. When the rotating shaft 12 rotates one circle, the bass drum will be struck once to make a "dong" sound. The fourth striking assembly 5 is used to strike the snare drum. The snare drum is small in size and is usually struck with a drumstick. The fourth cam is provided with an abutment block, so when the rotating shaft 12 rotates one circle, the snare drum will be struck once to make a "da" sound. And because the abutment block on the fourth cam is opposite to the abutment block on the second cam, when the rotating shaft 12 rotates one circle, the sound of "dong times, da times" will be emitted once. Among them, the sound of "times" is always there, but it will be covered by the drum sound.
[0039] In the present application, the drumsticks and pedals can use sensors to sense the lifting of the striking components to transmit electrical signals and connect to external audio equipment to play sound effects. The device can also be directly deployed on a drum set to perform actual physical striking to produce related sounds. These external connection structures are technical means that should be known to technical personnel in this field, and therefore will not be described in detail in the present application.
[0040] Furthermore, the third striking component 4 is used for backup, and can strike the cymbals to produce harmony, or strike the drums to produce harmony, and can also be disabled.
[0041] Furthermore, the first striking assembly 2 and the fourth striking assembly 5 have the same rotation direction; the second striking assembly 3 and the third striking assembly 4 have the same rotation direction; and the first striking assembly 2 and the second striking assembly 3 have the same rotation direction.
[0042] Furthermore, the first striking assembly 2 and the fourth striking assembly 5 have the same rotation direction; the second striking assembly 3 and the third striking assembly 4 have the same rotation direction; and the first striking assembly 2 and the second striking assembly 3 have opposite rotation directions.
[0043] Specifically, because the bass drum pedal can be stepped on by the toe or the heel, the setting directions of the second percussion component and the third percussion component can be adjusted according to actual needs.
[0044] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the claims of the present invention and the scope of equivalent technologies, the present invention is also intended to include these changes and modifications.
