Description

Piano for children

Technical Field

The invention relates to the technical field of children music education toys, in particular to a piano for children.

Background

Nowadays, more and more parents have their children receive good music education from childhood. The piano is a musical instrument which can enlighten the intelligence of children, and the learning piano has the advantages of improving the personal culture and culture quality of the children, developing the intelligence, cultivating the harmony, cultivating the appreciation power of the children on music and exercising the endurance and the confidence of people.

A piano is generally required for children to learn the piano, but the cost of the piano is relatively high, so that many parents can select a piano for children to cultivate the interest of the children, and then decide whether to convert the piano into formal learning.

The piano produces sound by pressing down the keys by the player, and the keys pull a small mallet arranged in the piano and then strike the steel wire to produce sound. However, most of the toy pianos on the market at present are electronic toy pianos.

The electronic toy piano mainly adopts the combination mode of plastic casing and electronic components, plays music sound through the button. The whole sound production process depends on a simple frequency division analog circuit, so the keyboard has no dynamics and string hitting feeling, the sound is mechanical and monotonous, and the simulation effect cannot be really achieved.

There are a few toy pianos for children, which use ferromanganese bars as sound producing devices, and strike the ferromanganese bars through striking members connected by key driving, to produce striking sounds. However, when the piano key is pressed, the key may collide with the component to which the piano key is mounted during the movement, and noise is generated, which affects the quality of sound.
