Panasonic has developed a loudspeaker using a diaphragm that is made with plant opals in bamboo leaves for the first time in the industry to improve sound quality. The new Bamboo Plant Opal Loudspeaker can reproduce clear sound with low distortion, thanks to the use of the hard, plant opal materials occurring in bamboo for the diaphragm.

Audio loudspeakers need to reproduce high sound quality with low distortion in wide frequencies range. Therefore, loudspeaker diaphragm materials need to be lightweight and have high rigidity, in order to improving the acoustic velocity and prevent unnecessary resonance.

Panasonic used diaphragms made of resin containing bamboo fibers and bamboo charcoal. The diaphragm in the loudspeaker now uses an additional bamboo-derived material - hard, needle-shaped plant opals in bamboo leaves, resulting to accurate reproduction of audio as close as posible to the original sound, and less distortion compared to the company's existing loudspeakers.



The new loudspeaker is suitable for automotive and home audio systems and will be available on March 1.
