Both listening and reading machines and point reading machines are electronic products of preschool education.

The principle of point reading machine is that in the process of making pronunciation files, the "latitude and longitude position" corresponding to the book content is preset for pronunciation files. The user puts the textbook on the tablet of the machine, and points the words, pictures, numbers and other contents on the book with a special pen, and the machine will make corresponding sounds. The listening and reading machine is a teaching machine that integrates HIFI speakers with dozens of classic textbooks of Chinese studies, hundreds of Suzuki all-around music and Chinese classical music, as well as English Shakespeare's English classics, moral education stories, fairy tales, Chinese and English nursery rhymes and encyclopedia knowledge. Just plug it in, turn it on, and enjoy the feeling of being with your master. If you want to listen, please use the remote control according to the catalogue.
