Description

Technical Field

[0001] The invention relates to the technical field of children's music education toys, and in particular to a children's piano. Background Art

[0002] Nowadays, more and more parents let their children receive good music education from an early age. Piano is an instrument that can greatly inspire children's intelligence. The benefits of learning piano are that it can improve children's personal accomplishment and cultural quality, develop intelligence, cultivate coordination, cultivate children's appreciation of music, and exercise people's endurance and confidence.

[0003] If children want to learn piano, they generally need a piano. However, the cost of a piano is relatively high, so many parents will choose a children's piano to cultivate their children's interest and then decide whether to convert it into formal learning later.

[0004] The piano produces sound by the player pressing a key, which moves a small mallet provided in the piano, and then strikes a steel wire to produce sound. However, most of the toy pianos on the market are electronic toy pianos.

[0005] Electronic toy pianos mainly use a combination of plastic shells and electronic components to play music by pressing keys. The entire sound-generating process relies on a simple frequency-dividing analog circuit, so the keyboard has no strength or string-strike feeling, and the sound is relatively mechanical and monotonous, which cannot truly achieve the simulation effect.

[0006] There are a small number of children's toy pianos that use ferromanganese bars as sound-generating components, which produce percussion sounds by hitting the ferromanganese bars through the percussion components connected to the keys. However, when the piano keys are pressed, the keys will collide with the components on which the piano keys are installed during the movement, producing noise and affecting the sound quality. Summary of the invention

[0007] In view of the above-mentioned technical problems, the present technical solution provides a children's piano that can effectively solve the above-mentioned problems.

[0008] The present invention is achieved through the following technical solutions:

[0009] A children's piano comprises a piano frame, one side of the piano frame is provided with piano keys, and the other side is provided with a sound cavity; the piano keys extend to the inner side of the sound cavity after passing through a partition; in the sound cavity, a sound-generating device for generating sound by striking the piano keys is provided on the upper side of the piano keys, and a sound cavity cover is detachably fixed on the top of the sound-generating device; the sound-generating device comprises a group of sound tubes, and the sound tubes are fixedly mounted on a sound tube bracket through gaskets; the sound tubes comprise a plurality of metal hollow tubes arranged in sequence, and the plurality of metal hollow tubes are arranged in a structure according to musical temperament with different lengths; the gasket is provided with slots corresponding to the metal hollow tubes, and the plurality of metal hollow tubes are installed and fixed in the plurality of slots at intervals; a piano key mounting seat is installed between the piano keys and the bottom plate of the piano frame, and soft pads for eliminating noise are provided on the piano key mounting seat, the bottom surface of the partition and the bottom plate of the piano frame at the parts that contact the piano keys when they move.

[0010] Furthermore, the sound pipe bracket includes end brackets arranged at left and right ends, and the front and rear sides of the bottom of the end bracket are fixed as a whole by connecting rods; the bottom surface of the gasket is fixed on the connecting rod, and the top surface of the gasket is higher than or equal to the top surface of the end bracket. A fixing plate with multiple sound holes is arranged on the upper side of the gasket, and the left and right ends of the fixing plate are respectively fixed on the top surface of the end bracket.

[0011] Furthermore, the gasket includes an upper gasket and a lower gasket, and the upper gasket and the lower gasket are respectively provided with grooves at the positions where the metal hollow tube is installed, and the metal hollow tube is installed in the grooves and fixed in a limited position.

[0012] Furthermore, the gasket is an integral structure, and is provided with through holes at positions where the metal hollow tubes are installed, and the metal hollow tubes are installed and fixed in the through holes.

[0013] Furthermore, the piano key includes a key and a striking device, and the key and the striking device are connected by a rotating shaft. The inner side surface of the piano key mounting seat is provided with a suspended step, and the starting end of the striking device is clamped on the lower side of the step; an arc-shaped protrusion is provided at the position where the striking device acts on the metal hollow tube, and the arc-shaped protrusion strikes the metal hollow tube to produce a sound.

[0014] Furthermore, the piano key mounting seat is fixed to the bottom plate of the piano frame by fasteners, and the soft cushion is fixed to the piano key mounting seat or the bottom plate of the piano frame by adhesive.

[0015] Furthermore, an elastic card is provided on the bottom edge of the inner side of the partition, and a plurality of contact pieces acting on the piano keys are provided on the elastic card. The bottom surface of the contact piece is connected to the top surface of the piano key. When the piano key is pressed, the contact piece can assist the piano key to rebound to its original position.

[0016] Furthermore, one end of the piano cover is connected to one end of the piano frame through a hinge; a support column is installed at the other end of the piano cover and the other end of the piano frame through a hinge; and a limiting hole acting on the support column is provided on the inner surface of the piano cover.

[0017] Furthermore, a limit rope is arranged on the inner side surface of the piano cover, and the other end of the limit rope is fixed on the sound cavity cover plate.

[0018] Furthermore, a buffer pad is provided on the inner surface of the piano cover which contacts the top surface of the piano frame.

[0019] (III) Beneficial effects

[0020] Compared with the prior art, the children's piano proposed by the present invention has the following beneficial effects:

[0021] (1) In the technical solution, the partition is arranged so that the partition and the piano frame form a sound cavity, and the sound-generating device is installed in the sound cavity. When the striking device strikes the sound-generating device, the sound waves emitted will rotate in the sound cavity, forming a simulated echo state; thus, the sound quality of the piano is more ethereal and mellow, and at the same time, the duration of the sound is increased, making the sound of the piano more pleasant to the ears.

[0022] (2) In this technical solution, soft pads for eliminating noise are provided on the piano key mounting seat, the bottom surface of the partition and the bottom plate of the piano frame, where the piano keys are in contact with them when they are moving, so that noise can be eliminated and the sound of the piano can be clearer. Furthermore, the provision of the soft pads can provide a certain buffering force when the keys are pressed, which can relatively reduce the impact of the reaction force on the child's hands, making it easier for the child to play and increasing the child's comfort during the playing process.

[0023] (3) In the technical solution, the key is connected to the striking device, so that the key drives the striking device to strike the sound-generating device, which can increase the strength of the keyboard strikes and simulate the feeling of striking the strings of a real piano.

[0024] (4) The sound-generating device in the technical solution uses an arrangement of aluminum alloy hollow tubes as a sound-generating component. The different lengths of the aluminum alloy hollow tubes are used to achieve the correspondence of different tones and melodies. The aluminum alloy hollow tubes are fixed on a sound tube bracket, and the sound tube bracket is fixed on the bracket of the generating device. Together with the piano case and the percussion device, the sound-generating device for a toy piano for children is formed. The structural design is reasonable and can be used as a similar piano instrument. It uses an aluminum alloy tube as a sound-generating component, and can adjust the sound quality by punching holes. It can be used as a sound-generating device for a toy piano for children. It is practical, low-cost and has a long service life.

[0025] (5) In this technical solution, the metal hollow tubes are separated by gaskets, which can effectively isolate the metal hollow tubes. At the same time, the metal hollow tubes are also effectively isolated from the sound pipe bracket and the fixing plate. This prevents the metal hollow tubes from contacting each other, and the metal hollow tubes from contacting the sound pipe bracket and the fixing plate, which are materials with greater hardness. This effectively avoids collisions between the three and produces noise. This can effectively improve the sound quality of the central control metal tube. This plays an auxiliary role in improving the sound quality of the piano's generator. BRIEF DESCRIPTION OF THE DRAWINGS
