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: Acoustic transducers may, in certain aspects, include a curved diaphragm and an actuator coupled to the curved diaphragm to cause movement of the curved diaphragm. In certain embodiments, the curved diaphragm has at least one free edge. The left and right edges of the curved diaphragm may be associated with auxiliary supports. The acoustic transducer can be a multi-pole loudspeaker wherein a curved diaphragm radiates the sound energy in a modified dipole pattern. The curvature of the radiating surface of the transducer reduces sound cancellation from sound energy reflected by nearby surfaces.

Abstract: The invention generally relates to acoustic transducers. In certain aspects, the acoustic transducer includes a diaphragm and a piezoelectric actuator coupled to the diaphragm to cause movement of the diaphragm. In certain aspects, the transducer also includes a member that limits bending of the actuator.

Abstract: The invention generally relates to acoustic transducers. In certain aspects, the acoustic transducer includes a diaphragm and an actuator. In further aspects, the acoustic transducer includes a connector having a planar proximal end that tapers to a distal end. The proximal end may be coupled to the diaphragm and the distal end coupled to the actuator, such that the actuator causes movement of the diaphragm. In additional aspects, the acoustic transducer includes a connector having a proximal end that couples to the diaphragm and a distal end that couples to the actuator. The proximal end of the connector can include a damping element. In other aspects, the diaphragm includes a connector, in which the connector tapers to a distal end that is configured to mate with the actuator such that the actuator causes movement of the diaphragm.

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.

Abstract: An acoustic transducer is disclosed that is capable of converting mechanical motion into acoustical energy may include a diaphragm and a support on one portion of the diaphragm. An actuator may then be provided that is operatively coupled to a second portion of the diaphragm. The support and actuator may be configured to be environmentally responsive to surrounding conditions of, e.g., heat and/or humidity which may then substantially maintain the diaphragm's acoustic performance.
