ABSTRACT:
A multifunctional transducer diaphragm may be configured as audio speaker system for displays wherein the multifunctional transducer diaphragm is capable of polarizing light transmitted therethrough and can convert mechanical motion into acoustical energy. In a related embodiment, a display panel system may comprise a multifunctional display screen comprising a single multifunctional transducer diaphragm capable of polarizing light which converts mechanical motion into acoustical energy, simultaneously providing both display screen and audio speaker functionalities.
