Abstract
A transducer generates acoustic energy. The transducer is suitable for incorporation into any device that needs sound reproduction capability, including devices with generally rectangular geometries such as cell phones, PDAs, and portable gaming devices. The transducer includes a displaceable membrane with a deformable corner. The deformable corner may extend the frequency range over which the transducer generates acoustic energy without distortion. The deformable corner may be part of a membrane periphery around the displaceable membrane. The membrane periphery may be square, triangular, or may take any other polygonal shape.
Claims20
A transducer comprising:
- a displaceable membrane;
- a deformable corner coupled to the displaceable membrane, the membrane periphery comprising the deformable corner;
- and
- an intermediate membrane between the displaceable membrane and the deformable corner, and where the intermediate membrane has a first thickness, and at least a portion of the membrane periphery has a second thickness different than the first thickness.
A transducer comprising;
- a displaceable membrane;
- a deformable corner;
- and
- an intermediate membrane between the displaceable membrane and the deformable corner;
- where the displaceable membrane, the deformable corner, and the intermediate membrane are formed from a single sheet of membrane material.
A transducer comprising:
- a displaceable membrane;
- and
- a membrane periphery coupled to the displaceable membrane;
- where the membrane periphery comprises a deformable corner comprising crests configured to facilitate deformation of a portion of the membrane periphery.
