Abstract: The present disclosure relates to a diaphragm that may be used with a mechanical-to-acoustical transducer. The diaphragm may include a layer of optically clear film, a damping layer and another layer of optically clear film. The damping layer may be an adhesive. The diaphragm may also comprise two optically clear films, optionally including a damping layer, wherein the films indicate a desired coefficient of linear thermal expansion in one or both of the machine and transverse directions.

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.
