CIMERA® multilayer composite materials can be used for flat or formed loudspeaker diaphragms such as plates, cones or domes. CIMERA® allows very high stiffness even for flat and slightly formed structures.
Most important requirements for loudspeaker diaphragms:
- High break-up frequency / wide “pistonic” range
- High damping / no peaks in SPL response
- Low weight for high sensitivity or magnet cost saving
- High temperature resistance
Solid materials show high stiffness OR high damping - CIMERA® sandwich materials combine both!
