Corrugated loudspeaker

Listening to music is a very pleasant thing, but for people with poor hearing, what is easy in the eyes of ordinary people is their dream. As a result, some people are now working on new ways to make people feel sound, such as by looking or touching. This corrugated speaker is through the vibration of music to stimulate the deaf brain waves to make it active, through this way to enjoy the beauty of music. As the melody vibrates, the needles on the speakers move up and down, and deaf people can feel the music by looking at it or putting their hands on it.
