Views: 13<\/p>\n

Not long ago researchers at MIT have shown a loudspeaker that is thinner than a sheet of paper. It has a thickness of a few microns and the novelty is the way it has to generate the sound.<\/p>\n\n\n\n

Until now, the speakers we know have a membrane that vibrates and produces sound waves. In this new case it is a piezoelectric material where there are small domes that vibrate individually when the electric current passes through them, and these domes measure one sixth of the thickness of a human hair.<\/p>\n\n\n\n

Being so small, they are very sensitive to the passage of current and therefore sounds are generated with much lower consumption than current speakers. On the order of a tenth.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Once the prototype is made, it remains to be seen the quality of the sound in all frequencies (especially those that are audible) to find practical applications in different markets.<\/p>\n\n\n\n

In the following video you can see a small demonstration: https:\/\/dai.ly\/x8ae1yq<\/a><\/p>\n\n\n\n

Size and consumption are two very important advantages, but the quality of the sound it provides is essential for some types of market.<\/p>\n\n\n\n

Being so fine, it can be adapted to any type of surface, both straight and curved, thus increasing the number of its possible applications.<\/p>\n\n\n\n

It seems ideal for use in closed places such as cars, planes, etc... in which it is important to reduce environmental noise, since this is achieved by applying a sound signal in phase opposition to that of ambient noise, and here quality is not the most important.<\/p>\n\n\n\n

It could also be useful in some devices that have very little power to drive a speaker. But I don't see it competing with a home audio system with good bass quality.<\/p>\n\n\n\n

At the moment it is a very interesting development, and it remains to be seen how far it can go in its practical applications. But again, it is interesting.<\/p>","protected":false},"excerpt":{"rendered":"
