Abstract: Techniques for providing multiple power supplies in electronic devices are disclosed. According to one aspect of the present invention, an appropriate power supply is provided only to accommodate a volume setting. In other words, there are at least two power supplies, one with a low voltage and the other with a high voltage. The high voltage power supply is only applied when there is a need to accommodate a volume setting. Thus the power consumption of the amplifiers is well controlled. As a result, the designs of the device and heat dissipation therein can be simplified and lowered in cost.

Abstract: An example method includes detecting a connection between a dock interface of a first zone player and a portable device, the dock interface providing communication between the portable device and a second zone player, wherein the second zone player is part of a first set of zones in a playback network that does not include the first zone player; responsive to the detection, transmitting data to cause the second zone player to modify parameter(s) of the second zone player according to a zone scene; responsive to the detection, determining that the portable device was playing a media item; and causing, via the dock interface, playback of the media item from the portable device by the first zone player and the second zone player while the second zone player is in the second set of zones.

Abstract: Systems, methods, apparatus, and articles of manufacture to control audio playback devices via a playback network including a dock interface are disclosed. An example dock includes a docking connection to enable a portable playback device to be connected to the dock and a network communication interface to enable the portable playback device to connect to a playback network via the dock, the network communication interface to provide content from the portable playback device to at least one network playback device for playback of the content via the playback network.
