Abstract: The present disclosure relates to a balanced armature receiver (100) including a housing having a diaphragm comprising a movable paddle (116) disposed in the housing and separating the housing into a back volume (112) and a front volume (110) defined partly by space between a ceiling of the housing and the diaphragm, wherein the paddle is oriented non-parallel to the ceiling. A sound port (142) in the housing acoustically couples the front volume to an exterior of the housing, wherein the sound port is located on an end wall between the diaphragm and the ceiling. A motor disposed in the back volume includes a coil magnetically coupled to an armature having an end portion movably disposed between magnets retained by a yoke and coupled to the paddle.

Abstract: A diaphragm assembly disposed in a receiver and includes a support structure. The support structure is generally rectangular and has a length that extends along a longitudinal axis. The support structure has a width that is generally perpendicular to the longitudinal axis. The length is greater than the width. The assembly includes a paddle and a membrane, and the membrane extends over and being supported by the support structure and paddle. A gap is disposed between the paddle and the support structure. A plurality of tabs extend across the gap and connecting the paddle and support structure. The tabs are located along the length of the support structure and extend outward from the longitudinal axis across the gap. The tabs move in a twisting motion and not bending motion as the paddle moves.
