Abstract
A microphone includes a housing including a substrate and a cover disposed over the substrate, the housing including a sound port between the interior of the housing and the exterior of the housing. The microphone also includes a microelectromechanical systems (MEMS) transducer and an integrated circuit (IC) positioned within the housing and mounted on a common surface of the housing, where the MEMS transducer is electrically connected to the IC, and the IC is electrically connected to a conductor on the substrate. The microphone further includes an encapsulating material covering the IC, and an encapsulating material confinement structure disposed between the MEMS transducer and the IC, where the encapsulating material confinement structure at least partially confines the encapsulating material around the IC.
