The microphone sensing element has a circular or polygonal diaphragm with a plurality of perforated springs suspended above the front side of a conductive substrate. The diaphragm is aligned above one or more back holes in the substrate having a front opening smaller than the diaphragm. In one embodiment, a continuous perforated spring surrounds the diaphragm and has a shape that conforms to the diaphragm. A plurality of perforated beams connects the spring to rigid pads that anchor the movable diaphragm and spring. In another embodiment, there is a plurality of perforated springs having double or triple folding configurations and a plurality of perforated beams connecting the diaphragm to rigid pads. Also disclosed is a scheme to integrate the silicon microphone sensing element with CMOS devices on a single chip.

Abstract: A loudspeaker driver has a diaphragm connected to a surrounding frame by a roll suspension which extends around the diaphragm and within the frame. The roll suspension connects the outer edge of the diaphragm to the inner edge of the frame and flexes as the diaphragm is displaced to and fro axially relative to the frame. In order to provide for better integrity of the roll suspension during its displacement, and reduce unwanted deformation and concomitant distortion, the suspension roll is provided with pleats extending across the roll suspension transversely to the direction of axial movement of the diaphragm to create a series of undulations (peaks and troughs) around the perimeter of the roll suspension. In transverse cross-section, the roll suspension is parabolic. The roll suspension varies continuously between each peak and adjacent trough. Preferably, outer surfaces of each peak and adjacent trough merge to a common point on the outer edge of the roll, while their inner surfaces merge to a common point on the outer edge of the roll, such that the peaks and troughs effectively disappear.

Abstract: An ultra low frequency transducer or subwoofer for automotive speaker systems with a rectangular or square or otherwise polygonal diaphragm. The basket of the transducer has a correspondingly polygonal front, which preferably is sized to be substantially coextensive with the front of the speaker housing or cabinet. In this way, air displacement in the subwoofer is maximized for a given size of enclosure, and thus so is the loudness of the speaker. The preferred diaphragm is concave, and the transducer preferably includes a convex surround with pleated corners. For increased durability, trusses are formed in the diaphragm.
