Harvard scientists create a transparent gel speaker reproduces a better sound quality than current systems. Technology can revolutionize the sound reproduction in the future.
Is it hard to believe? The transparent gel disc in the photo above is a fully functional speaker connected to a mobile phone. The loudspeaker is active cancellation system external sound and produces sound with greater clarity than current systems. If you like to customize the details of sound, this technology will allow better equalization.
Harvard scientists pioneered the application of ionic conductivity in an artificial muscle capable of producing sound.
Developed by a team from the School of Engineering and Applied Sciences at Harvard, Jeong Yun-Sun and Christoph Keplinger (pictured), knew ionic materials do not react well to high voltage, therefore, they introduced a layer of rubber between the two sheets of transparent conductive gel saltwater created, allowing the system to operate at high voltage.
The voltage conducted through the gel causes vibrations in the rubber of the sound reproducing apparatus sent from mobile phones or other devices.
The amazing thing is that the sound emitted frequencies from 20Hz to 20,000 Hz, ie the spectrum audible to the human ear. Watch the demo in the video below:
Clearly, this experiment can be improved in the future commercially phones, smartphones, TVs, etc.. The important thing is that the chances are increasing that arise innovations like this.
