Abstract:
1. An apparatus comprising: a frame having a first side and a second side opposite the first side, wherein the first side and the second side of the frame are opposing sides that bound a longest dimension of a transducer, the transducer comprising: an electromagnet including a conductive coil surrounding a ferrous core, wherein the conductive coil is configured to be driven by an electrical input signal to generate magnetic fields, wherein the electromagnet is mounted to the frame; a magnetic diaphragm that is configured to mechanically vibrate in response to the generated magnetic fields; and a first flexible support arm and a second flexible support arm that elastically couple the magnetic diaphragm to the frame such that the magnetic diaphragm vibrates with respect to the frame when the electromagnet is driven by the electrical input signal, wherein the first flexible support arm extends from the frame at a location proximate the first side of the frame, to a side of the magnetic diaphragm proximate the second side of the frame, wherein the second flexible support arm extends from the frame at a location proximate the second side of the frame, to a side of the magnetic diaphragm proximate the first side of the frame, and wherein each of the first and second flexible support arms extend along the longest dimension of the transducer, adjacent respective opposing sides of the magnetic diaphragm that are free of connection to either of the flexible support arms.
