Abstract
Official abstract text for this publication.
A microphone includes a microphone base that has a first surface and a second surface. The microphone also includes a microelectromechanical system (MEMS) device coupled to the first surface of the microphone base. The microphone also includes a cover coupled to the first surface of the microphone base, such that the cover divides the first surface into a covered portion where the cover encloses the MEMS device, and a non-covered portion extending away from the cover. The microphone also includes one or more pads on the uncovered portion of the first surface of the base. The microphone also includes a port extending through the base from the first surface to the second surface.
First claim
Opening claim text (preview).
What is claimed is: 1 . A microphone, comprising; a microphone base, the microphone base having a first surface and a second surface; a microelectromechanical system (MEMS) device coupled to the first surface of the microphone base; a cover coupled to the first surface of the microphone base, such that the cover divides the first surface into a covered portion where the cover encloses the MEMS device, and a non-covered portion extending away from the cover; one or more pads on the uncovered portion of the first surface of the base; and a sound port extending through the base from the first surface to the second surface. 2 . The microphone of claim 1 , further comprising an integrated circuit disposed on the covered portion of the first surface. 3 . The microphone of claim 1 , wherein the first surface and the second surface are parallel and do not intersect. 4 . The microphone of claim 1 , wherein the second surface remains uncoupled to a customer device. 5 . The microphone of claim 1 , wherein the one or more pads is coupled to a customer device. 6 . The microphone of claim 1 , further comprising a barrier over the sound port. 7 . The microphone of claim 1 , wherein the sound port has a diameter greater than 1 mm. 8 . The microphone of claim 1 , wherein the microphone is disposed within a customer device such that the device is disposed as a top port device within the customer device.
