Abstract: Embodiments are provided for components configured for audio playback. According to certain aspects, a transducer includes dual voice coils disposed in a magnet section, whereby the magnet section generates an electromagnetic field that causes the dual voice coils to actuate in response to an applied audio signal. The transducer further includes a diaphragm coupled to the dual voice coils that actuates according to the dual voice coils and produces audio output. In some implementations, the transducer may be disposed within a cutout area of an electronic device, whereby the transducer is secured to the electronic device via a roll-surround suspension.

Abstract: An electrostatic speaker is described that includes a curved diaphragm positioned between two electrically conductive plates. According to aspects, the curved diaphragm has an “S-shape” and is configured to electrostatically move between the conductive plates. In particular, the curved diaphragm may generally roll between the two conductive plates so as to move from left to right with respect to ends of the conductive plates and push air in a direction toward ends of the conductive plates, thus generating acoustic output. In some implementations, the configuration of the electrostatic speaker reduces a biasing voltage required for the conductive plates.
