Problems solved by technology

[0002] Most of the existing language learning machines use traditional audio tapes as the teaching material carrier. It is difficult to find the content to be learned when using them, and the audio tapes are often turned upside down and easily jammed, and even the transmission parts are damaged, so the service life is short.
In addition, MP3 players are audio-visual entertainment products that mainly play music. They can convert tape teaching materials into MP3 format to use MP3 players for learning, but they store data in MP3 format, and each minute of content takes up about 1M. If it is used to store teaching materials, it requires a huge storage capacity, so the cost is expensive

Description

【Technical field】 [0001] The invention relates to a digital language learning machine, in particular to a digital language learning machine with the functions of repetition, follow-up, comparison, MP3 and the like. 【Background technique】 [0002] Most of the teaching materials used in existing language learning machines are traditional audio tapes. It is difficult to find the content to be learned during use, and the audio tapes are often tossed up and down and easily jammed, and even the transmission parts are damaged, so the service life is short. In addition, the MP3 player is an audio-visual entertainment product that mainly plays music. It can convert the tape textbooks into MP3 format to use the MP3 player for learning, but it stores data in the MP3 format, and the content of each minute takes up about 1M. If it is used to store teaching materials, it requires a huge storage capacity, so the cost is expensive. 【Content of invention】 [0003] The technical problem to...
