Damping spring
Abstract:
Embodiments disclosed in the present disclosure relate to vibration transducers. Such a transducer includes an electromagnet having a conductive coil. The conductive coil is configured to be driven by an electrical input signal to generate magnetic fields. The transducer further includes a magnetic diaphragm that is configured to mechanically vibrate in response to the generated magnetic fields. Additionally, the transducer includes a pair of cantilevered arms formed from damping steel. The cantilevered arms couple the magnetic diaphragm to a frame. The magnetic diaphragm vibrates with respect to the frame when the electromagnet is driven by the electrical input signal. Additionally, the pair of flexible support arms are connected to opposing sides of the magnetic diaphragm.
