Description

Technical Field

[0001] The invention relates to a music box, in particular to a music box capable of arranging music. Background Art

[0002] The music box is a mechanical musical instrument that can play music automatically and is deeply loved by people. The traditional music box is mainly composed of a spring, a drum and a reed. The reed is cut into steel comb-shaped teeth of equal width and different lengths. The surface of the drum is provided with a plurality of protrusions arranged according to the music. Its main working principle is: when the spring is tightened, the spring drives the drum with protrusions on the surface to rotate. When the reed passes through the protrusions arranged according to the music, the protrusions pluck the reed, so that the reed vibrates at the set vibration frequency and emits the set sound.

[0003] The mainspring and reed of the music box are simple to make, but the arrangement and combination of the protrusions on the drum (i.e. the music score) generally needs to be welded to the drum by professional craftsmen, which is difficult and time-consuming. Once the welding is completed, it is difficult to disassemble, which means that the music of the music box cannot be changed and is relatively simple. In addition, the working cycle is limited due to the diameter limitation of the drum, and the duration of the music played is also affected. Summary of the invention

[0004] In order to solve the deficiencies in the above-mentioned prior art, the present invention provides a music box that can be arranged, which is relatively easy to manufacture and can achieve the purpose of adjusting the music, thereby playing more music and extending the playing time.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: an arrangeable music box, comprising a base plate and a soundboard, wherein the soundboard is fixed on the base plate, and the soundboard comprises a plurality of reeds which are spaced side by side and have different masses, the arrangeable music box also comprises a support frame and a plurality of plectrums, wherein the support frame is fixed on the base plate, a plurality of plectrums are spaced side by side in the support frame, and a driving mechanism for driving the plectrums to touch the corresponding reeds is also arranged in the support frame.

[0006] A transversely distributed fixed shaft is fixed in the support frame, and a plurality of the plectrums are rotatably connected to the fixed shaft, and one end of each plectrum has a provoking portion in a triangular structure, and one end of each spring is provided with a touching portion in a triangular structure. When the driving mechanism drives the plectrum to rotate around the fixed shaft, the provoking portion contacts the touching portion. In this structure, the plectrum is rotatably connected to the fixed shaft, and the driving mechanism is used to drive the plectrum to rotate around the fixed shaft. The distance between the front end of the plectrum and the fixed shaft is smaller than the distance between the rear end of the plectrum and the fixed shaft, which is conducive to the lever principle. Only a small force is needed to drive the provoking portion of the plectrum to contact the touching portion of the spring, so that the spring vibrates and sounds. The provoking portion and the touching portion are both triangular structures, which is conducive to the inclined surface between the two and the upward and downward displacement of the provoking portion.

[0007] The driving mechanism includes a first guide wheel, a second guide wheel, a tape, a permanent magnet and a mounting column. A plurality of chambers for accommodating the paddles are provided in the support frame, and the plurality of chambers are independent of each other. The first guide wheel and the second guide wheel are rotatably arranged in the chambers respectively, and the first guide wheel and the second guide wheel are distributed up and down. The tape is wound between the first guide wheel and the second guide wheel, and the other end of the paddle is fixed to the tape. The mounting column is arranged to pass through from top to bottom and is vertically connected in the support frame. An electromagnetic coil is also arranged in the mounting column. The permanent magnet is located in the mounting column and is coaxially distributed with the mounting column. The permanent magnet is also fixed to the tape. In this structure, each pick is located in an independent chamber, and the width of the chamber is 0.1-0.2mm larger than the thickness of the pick, which can prevent the pick from shifting left and right and play a better limiting role. The tape is wound between the first guide wheel and the second guide wheel. A vertically distributed first through hole is opened at the rear of the pick, and a vertically distributed second through hole is opened on the permanent magnet. The tape is passed through the first through hole and the second through hole and fixed to the pick and the permanent magnet. The pick and the permanent magnet are respectively located on both sides of the first guide wheel. When the permanent magnet moves upward, the tape is driven to rotate counterclockwise, and the tail of the pick When the pick moves downward, the plucking part moves upward, plucking the touch part, causing the reed to make a sound. When the permanent magnet moves downward, it drives the tape to rotate clockwise, the tail of the plucking piece moves upward, the plucking part moves downward, and plucking the touch part again causes the reed to make a sound, and this is repeated. The lifting and lowering of the permanent magnet is based on the principle of electromagnetism. When power is applied to both ends of the electromagnetic coil, a magnetic field is generated, which is beneficial to the principle of like repels like and unlike attracts like. The permanent magnet can move vertically in the mounting column, and after changing the direction of the current, the permanent magnet can move in the opposite direction, thereby realizing the lifting and lowering movement of the permanent magnet.

[0008] A bearing is fixed in each of the plectrums, and the inner ring of the bearing is coaxially fixed with the fixed shaft. The advantage is that the plectrums can be smoothly driven to rotate around the fixed shaft.

[0009] The provoking part has a first inclined surface and a second inclined surface, and the first inclined surface and the second inclined surface are connected by a first arc surface, and the angles between the first inclined surface and the second inclined surface and the horizontal plane are both between 15° and 30°. In this structure, the first inclined surface and the second inclined surface are transitionally connected by the first arc surface, which is conducive to contact with the touch part on the one hand, and can slide smoothly after contact on the other hand. The angles between the first inclined surface and the second inclined surface and the horizontal plane are both between 15° and 30°, so that the separation of the provoking part and the touch part is smoother and the wear is less.

[0010] A resonance box is fixed on the bottom plate, and the resonance box has a resonance cavity that runs through the left and right sides. The soundboard also includes a connecting piece that is integrally made with the reed, and the connecting piece is horizontally fixed on the upper surface of the resonance box and is in direct contact with the resonance box, and the reed extends out of the resonance box. In this structure, the resonance box is made of metal material and is in direct contact with the connecting piece, which can amplify the sound of the reed according to the principle of resonance, and the reed extends out of the resonance box, which makes it easy to pluck the reed.

[0011] The width of the touch portion is smaller than the width of the spring sheet, and the touch portion has a third slope and a fourth slope, the third slope and the fourth slope are connected by a second arc surface, and the angles between the third slope and the fourth slope and the horizontal plane are both between 2°-8°. In this structure, the width of the touch portion is smaller than the width of the spring sheet, and is equal to the thickness of the provoking portion, so that it is convenient to precisely dock with the provoking portion. The third slope and the fourth slope are transitionally connected by the second arc surface, which is conducive to contact with the provoking portion on the one hand, and can slide smoothly after contact on the other hand. The angles between the third slope and the fourth slope and the horizontal plane are both between 2°-8°, so that the separation of the provoking portion and the touch portion is smoother and less worn.

[0012] The width of each reed is equal, and each reed is provided with a tuning hole of the same specification, and the distances between adjacent reeds are equal. In this structure, the width of the reed and the distances between adjacent reeds are equal, which is conducive to processing and manufacturing, and the tuning holes on each reed are also consistent, which greatly reduces the manufacturing process.

[0013] The length of the reed increases from left to right. In this structure, since the width of each reed is equal and the length increases from left to right, the mass of each reed is different, so different sounds can be produced. Compared with the traditional method of increasing the thickness, this structure is easier to implement and the processing is also more convenient.

[0014] The bottom plate is provided with adjustable feet around its periphery. In this structure, the setting of the adjustable feet is conducive to adjusting the height of the bottom plate.

[0015] Compared with the prior art, the advantages of the present invention are that multiple picks correspond to multiple reeds one by one, and the driving mechanism is used to drive the picks to touch the corresponding reeds. Compared with the traditional processing of the roller with protrusions, the manufacturing difficulty is greatly reduced, and each reed can make a sound independently, the playable songs can be adjusted at will, and the playing time is also extended.

In this structure, the paddle 4 is rotatably connected to the fixed shaft 32, and the driving mechanism 5 is used to drive the paddle 4 to rotate around the fixed shaft 32. The distance between the front end of the paddle 4 and the fixed shaft 32 is smaller than the distance between the rear end of the paddle 4 and the fixed shaft 32. This is beneficial to the lever principle, and only a small force is needed to drive the provoking portion 41 of the paddle 4 to contact the touching portion 22 of the reed 21, so that the reed 21 vibrates and makes a sound.
