Problems solved by technology

[0003] The springs and reeds of the above-mentioned music box are easy to make, but the arrangement and combination of protrusions on the drum (that is, the musical score) generally needs to be completed by professional hand-made workers who weld small iron cores on the drum, which is difficult and labor-intensive. , once the welding is completed, it is difficult to disassemble, which means that the repertoire of the music box is unchangeable, relatively single, and the working cycle is limited due to the limitation of the diameter of the drum, and the duration of the repertoire is also affected

Embodiment 1

[0025] Embodiment 1: As shown in the figure, a musical music box that can be composed includes a bottom plate 1 and a soundboard 2. The soundboard 2 is fixed on the bottom plate 1, and the soundboard 2 includes a plurality of reeds 21 that are spaced side by side and have different qualities. , the musical music box that can be composed also includes a support frame 3 and a plurality of plectrums 4, the support frame 3 is fixed on the base plate 1, and a plurality of plectrums 4 are arranged side by side in the support frame 3 at intervals, and the support frame 3 is also provided with a drive for driving The plectrum 4 touches the driving mechanism 5 corresponding to the reed 21 .

Embodiment 2

[0026] Embodiment 2: As shown in the figure, other structures are the same as Embodiment 1. The difference is that a fixed shaft 32 distributed laterally is fixed in the support frame 3, and a plurality of paddles 4 are respectively rotatably connected to the fixed shaft 32. , and one end of each plectrum 4 has a provocative portion 41 in a triangular structure, and one end of each reed 21 is provided with a touch portion 22 in a triangular structure. When the driving mechanism 5 drives the plectrum 4 to rotate around the fixed shaft 32 , the provocative part 41 is in contact with the touch part 22 . In this structure, the plectrum 4 is rotatably connected to the fixed shaft 32, and the driving mechanism 5 is used to drive the plectrum 4 to rotate around the fixed shaft 32, and the distance between the front end of the plectrum 4 and the fixed shaft 32 is smaller than that The distance between the shaft 32 is conducive to the principle of leverage, and only a small force can d...

Embodiment 3

[0030] Embodiment 3: As shown in the figure, other structures are the same as Embodiment 2, the difference is that the provocative part 41 has a first slope 43 and a second slope 44, and the first slope 43 and the second slope 44 pass through the second slope. An arc surface 45 is connected, and the included angles between the first slope 43 and the second slope 44 and the horizontal plane are both within 15°-30°. In this structure, the first inclined surface 43 and the second inclined surface 44 are transitionally connected through the first arc surface 5, on the one hand, it is beneficial to contact with the touch portion 22, and on the other hand, it can slide down smoothly after contact. 43 and the second inclined surface 44 have an included angle range of 15°-30° with the horizontal plane, so that the separation of the provocative portion 41 and the contact portion 22 is relatively smooth, and the wear is relatively small.

Abstract

The invention discloses a music box capable of arranging music. The music box comprises a bottom plate and a soundboard, the soundboard is fixed to the bottom plate and comprises a plurality of reeds which are distributed side by side at intervals and are different in mass, the music box further comprises a supporting frame and a plurality of poking pieces, the supporting frame is fixed to the bottom plate, and the poking pieces are arranged in the supporting frame side by side at intervals. A driving mechanism used for driving the poking pieces to touch the corresponding reeds is further arranged in the supporting frame. The music box has the advantages that the manufacturing difficulty is low, the purpose of adjusting the tracks is achieved, more tracks can be played, and the playing time is prolonged.

Description

technical field [0001] The invention relates to a music box, in particular to a music box which can compose music. Background technique [0002] Music box is a kind of mechanical pronunciation musical instrument, and it can play music automatically, is very popular among people. The traditional music box is mainly composed of springs, drums and reeds. The reeds are cut into steel comb-shaped racks of equal width and different lengths. The surface of the drum is provided with multiple protrusions compiled according to the music. The working principle is: when the mainspring is tightened, the mainspring drives the roller with protrusions on the surface to rotate, and when the reed passes through the protrusions programmed according to the movement, the protrusions move the reed, so that the reed moves according to the setting. Vibrates at the vibration frequency and emits the set sound. [0003] The springs and reeds of the above-mentioned music box are easy to make, but the...
