MG Electronics introduces a powerful, new, lightweight Megaphone. Energy Efficient and Ultra-Loud! Piezo Dynamic technology is a revolutionary technique that allows a megaphone to operate more efficiently and with less weight than ever before. Piezo Dynamic Technology utilizes full-sized diaphragms and ceramic wafers to create the full-frequency response and loudness of voice coil speakers, without the use of heavy, cumbersome magnets as in conventional megaphones, significantly reducing weight and current draw.
