Abstract: An apparatus with embedded water detection and heater includes a substrate including a number of conductive traces and a lid including multiple electrodes. Each electrode is coupled to at least one of the conductive traces through vias. A sensor is placed inside a cavity of the lid and is electrically coupled to one or more conductive traces of the substrate. A gel at least partially fills the lid and covers the sensor. The presence of water on the apparatus is detected by measuring a dielectric permittivity between at least two of the plurality of electrodes, and the electrodes can generate heat to eliminate the water.

Abstract: An electro-acoustic transducer has an acoustic diaphragm and a voice-coil. The diaphragm defines a first major surface. A flange extends from the diaphragm in a direction opposite the first major surface. The voice-coil has a first plurality of windings positioned adjacent to the acoustic diaphragm and a second plurality of windings positioned distally from the acoustic diaphragm. The flange overlaps the first plurality of windings. The flange and the windings can be adhesively bonded with each other to form a lap joint. The lap joint can transfer force from the voice-coil to the diaphragm.
