Description

Technical Field

[0001] The utility model belongs to the technical field of liquid crystal writing tablets, and specifically relates to a writing tablet with a special-shaped shell structure and having recording and playing functions. Background Art

[0002] A liquid crystal writing tablet is a product that combines a liquid crystal display and touch screen technology. By using a special electromagnetic pen (electromagnetic technology), an ordinary writing pen, or a finger (pressure or resistance technology), writing can be freely performed on the liquid crystal screen. When it is necessary to clear the written characters, only need to press the clear key.

[0003] The existing liquid crystal writing tablets generally realize painting through a painting pen, a drawing board, a control chip, and a liquid crystal screen. For example, a children's drawing board disclosed in the applicant's prior application CN213150063U includes a painting pen and a drawing board. The drawing board includes a top cover, a bottom case, a liquid crystal screen, a control chip, a metal sheet, and a power supply device. The top cover and the bottom case are installed together to form a shell. The shape of the shell lacks attraction to children. At the same time, since children have relatively small palms, there is a risk that the drawing board is easy to drop and break when held.

[0004] The prior art CN214586302U discloses a handwriting liquid crystal board, which includes a liquid crystal membrane, a front shell, a rear cover, a PCB board provided with a circuit, a power supply device, a control button, and a handwriting pen. The liquid crystal membrane is embedded in the front shell, the rear cover is installed at the bottom of the front shell, and the rear cover is located below the liquid crystal membrane. A writing area is provided on the front shell. This device also has the problem that the shell cannot attract children, and there is a risk that the writing tablet is easy to drop due to the lack of a holding structure on the shell.

[0005] In order to solve the above problems, the applicant proposes a writing tablet, which can not only conveniently erase handwriting traces, but also has a recording function and can play audio through a speaker inside the writing tablet. At the same time, since the shell has a protruding shape, and the protruding shape has a cartoon image, it is easy to attract the attention of children. Summary of the Utility Model
