BOSTON: Engineers at the Massachusetts Institute of Technology (MIT) have invented a loudspeaker as thin and flexible as paper that can be easily glued to various surfaces other than a wall and turned into a large loudspeaker.
Compared to existing loudspeakers, this "paper loudspeaker" requires only 10% power.

Ordinary speakers and loudspeakers use an electromagnetic (electromagnetic) effect, but this new speaker uses a "piezoelectric effect".
In a piezoelectric effect, when electricity is passed through a particular substance, it begins to vibrate, while when the substance is pressed, it begins to generate electricity.
The paper loudspeaker invented at MIT vibrates at the slightest electric current, which produces sound.
For better performance, the loudspeaker surface is perforated from time to time with hair-thin holes that allow it to stick out and emit sound. That is, its performance is maintained.
From "Metavers" to extremely short hearing aids and from the music industry to aerospace engineering, this thin loudspeaker can be used in countless fields.
For example, to reduce the internal noise of the cockpit in passenger planes, a layer of loudspeakers can be installed on the walls of the cockpit which will calm the interior of the cockpit by emitting sound waves which cancel the noise.
This and a vast world of unknown and unknown applications awaits these thin and flexible loudspeakers.
Note: Details of this research are published online in the latest issue of the research journal "I Triple e-Transactions on Industrial Electronics".
