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.
Claims24
A device that converts a mechanical motion into acoustic energy, the device comprising:
- a multi-layer diaphragm, wherein at least one of the layers is a damping layer that is positioned between two other layers;
- at least one support;
- and
- at least one mechanical-to-acoustical transducer including a distal portion coupled to the diaphragm and a proximal portion coupled to the support, wherein movement of the transducer causes movement of the diaphragm in a direction that is generally transverse to the direction of the movement of the transducer.
A device that converts a mechanical motion into acoustic energy, the device comprising:
- a curved multi-layer diaphragm, wherein at least one of the layers is a damping layer that is positioned between two other layers;
- at least one support;
- and
- at least one mechanical-to-acoustical transducer including a distal portion coupled to the diaphragm and a proximal portion coupled to the support, wherein movement of the transducer causes movement of the diaphragm in a direction that is generally transverse to the direction of the movement of the transducer.
A device that converts a mechanical motion into acoustic energy, the device comprising:
- a multi-layer diaphragm, wherein at least one of the layers functions as both an adhesive and a damping layer that is positioned between two other layers;
- at least one support;
- and
- at least one mechanical-to-acoustical transducer including a distal portion coupled to the diaphragm and a proximal portion coupled to the support, wherein movement of the transducer causes movement of the diaphragm in a direction that is generally transverse to the direction of the movement of the transducer.
