Description

technical field [0001] The invention relates to the field of early childhood education, in particular to an electronic sound-producing water canvas. Background technique [0002] At present, children usually use colored pens to paint, but because children are lively and active, it is very easy to scribble everywhere with colored pens, and it will be very troublesome to clean and manage at that time. In order to solve this problem, magnetic drawing boards and touch LCD drawing boards are usually used for children to draw. However, the display of magnetic drawing boards is very rough, and touch LCD drawing boards generally have small screens, resulting in high cost and easy damage to large screens. In terms of water canvas, there is currently a water canvas on the market, as long as it is stained with water, the corresponding pattern can be displayed, which solves the problem of children scribbling, and the water canvas can be set to a large size, and the cost is relatively lo...

[0002] At present, children usually use colored pens to paint, but because children are lively and active, it is very easy to scribble everywhere with colored pens, and it will be very troublesome to clean and manage

In order to solve this problem, children usually use magnetic drawing boards and touch LCD drawing boards to draw pictures, but the display of magnetic drawing boards is very rough, and touch LCD drawing boards generally have smaller screens, resulting in high cost and easy damage to large screens.

In terms of water canvas, there is currently a water canvas on the market, as long as it is stained with water, the corresponding pattern can be displayed, which solves the problem of children scribbling, and the water canvas can be set to a large size, and the cost is relatively low, but children It is just random painting on the water canvas, and it does not have the function of prompting and guiding children to paint and motivating children to learn, which greatly reduces the fun
