[0002] With the development of globalization and the increasing frequency of international communication, mastering a foreign language has become an essential skill in modern society. Listening practice is a crucial step in improving language comprehension. Traditional listening training methods typically use audio tapes or digital audio files, with students listening to the recordings and then completing corresponding written tasks, such as note-taking or dictation.
[0003] However, when doing listening and writing exercises, students often encounter some practical difficulties. When students are doing listening and writing exercises, once a writing error occurs, they need to use an eraser or other tools to manually erase the wrong part.

[0059] The working principle of a hearing device with an erasing function is as follows: the user can use the writing pen 800 to write, and the display 150 can play the standard writing content. When a writing error is made, or when there is other need to erase the writing on the surface of the writing board body 140, the user can pull up the writing pen 800 and pull the pull rope 720 outward, eventually making the power block 510 contact with the conductive column 400, powering the drive member 200, and using the cleaning eraser 210 to wipe the writing board body 140.
