Abstract
Systems and apparatuses are provided for vibration confinement and stress management in a loudspeaker. In one embodiment, the loudspeaker comprises a diaphragm that extends from an inner diaphragm region (e.g., dome or cone-shaped) to an outer diaphragm region, wherein the outer diaphragm region bends at a defined angle (e.g., between about 45 degrees and about 135 degrees) relative to the inner diaphragm region. The loudspeaker also comprises a suspension member extending from an inner suspension region to an outer suspension region, the inner suspension region overlapping and attaching with the outer diaphragm region. The bend in the diaphragm isolates the inner diaphragm region from spurious vibrations in the suspension member.
