Abstract
A movable diaphragm comprises a layer having a disc shape with undulating waves that extend from an inner diameter to an outer diameter. The layer is to be offset from a stationary surface and displaced toward the stationary surface, the displacement of the layer to effectively cause a respective compression and rarefaction of air between the layer and the stationary surface to an external environment. An annular surround is to seal outer edge portion of the layer to a transducer component, the surround having compliant properties to allow the displacement of the layer relative to the stationary surface and the transducer component without breaking the seal. The undulations increases an effective surface area of the layer to lower an overall size of the transducer that would otherwise be needed for a low frequency speaker.
