Producing low-frequency sounds from thin speakers, such as piezoelectric and film type, has always been a difficult task for manufacturers. Offering a solution, Tokai Rubber Industries has come up with an ultra-thin and elastic speaker made from artificial muscles that can produce low frequencies better than the speakers produced in the past.
Developed as a part of company’s new line, materials for artificial muscles, the rubber speaker places a piece of non-conductive rubber between two rubber electrodes that produce static electricity to expand the sheet. The frequent expansion and restorative force of the rubber sheet produces better sound waves even at low frequencies.
