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.

Abstract: Embodiments are provided for an improved peripheral speaker. The peripheral speaker includes an exterior casing enclosing one or more drivers. The exterior casing further has a channel formed therein such that the channel is sized to removably secure an electronic device. The exterior casing is equipped with a connector lead which partially defines the cavity and that connects the one or more drivers to a port of the electronic device. The one or more drivers output audio according to an audio signal transmitted from the electronic device via the connector lead.

Abstract: Embodiments are provided for mutually authenticating a pair of electronic devices. According to certain aspects, the electronic devices may connect to each other via an out-of-band communication channel. The electronic devices may each output audio signals and detect audio signals output by the other electronic devices. Based on timestamps associated with audio output and detection events, each of the electronic devices may calculate relevant time and distance parameters, and transmit the calculated parameters to the other electronic device via the out-of-band communication channel. The electronic devices may compare the calculated parameters to determine mutual authentication.
