Эта резина проводя ток может свободно расширяться и сжиматься для излучения звука.<br /><br />Точнее резиновый «динамик» состоит из куска непроводящей резины, зажатой между двумя резиновыми электродами. При подаче на электроды напряжения в виде аудиосигнала, статическое электричество заставляет резиновую пластину излучать звуковые волны. Ранее компания разработала гибкие сенсорные датчики. Идея резиновых динамиков возникла из результатов развития нового направления разработок компании: материалы для искусственных мышц. <br /><br />Многие сегодня используемые тонкие динамики относятся к пьезоэлектрическому типу, их основной недостаток – слабая эффективность при излучении низких частот (НЧ). Резиновые динамики наоборот позволяют эффективно излучать НЧ диапазон акустических волн. Впрочем, у компании Tokai Rubber пока нет конкретных планов по развитию акустической составляющей своего производства и бизнеса.<br /><br /><div align="center"><!--dle_image_begin:http://www.hdtv.ru/uploads/posts/2012-10/1350624224_ruber1.jpg|--><img src="http://www.hdtv.ru/uploads/posts/2012-10/1350624224_ruber1.jpg" alt="В Японии сделали полностью резиновый громкоговоритель" title="В Японии сделали полностью резиновый громкоговоритель"  /><!--dle_image_end--></div>
