Abstract
Described herein are systems, devices, and methods for generating a synchronized time value for a wireless speaker having a first timer and a second timer. In some embodiments, the systems, devices, and method may include reading a first timer value associated with the first timer, wherein the first timer is synchronized with a wireless network. Further, a first timer value associated with the second timer may be read. The first timer value associated with the second timer may be correlated to the first timer value associated with the first timer to generate the synchronized time value for the wireless speaker.
Claims20
A method for maintaining speaker group information at a host device having a processor and memory, the method comprising:
- receiving a speaker group identifier from a first speaker, wherein the speaker group identifier identifies a speaker group having one or more speakers;
- and
- storing the speaker group identifier within the memory.
The method according to claim 2, further comprising:
- generating a second speaker group identifier;
- and
- providing the second speaker group identifier to the first speaker.
A method for maintaining speaker group information at a first speaker having a processor and memory, the method comprising:
- receiving a first speaker group identifier from a first host device, wherein the first speaker group identifier identifies a speaker group having one or more speakers;
- and
- storing the first speaker group identifier within the memory.
A speaker comprising:
- a speaker driver;
- one or more circuits configured to provide an audio signal to the speaker driver;
- an internal power supply including:
- a charge storage device configured to supply power to the one or more circuits, and
- a first charging coil configured to receive power from an electromagnetic field and charge the charge storage device;
- and
- a housing enclosing at least a portion of the speaker driver, the one or more circuits, and the internal power supply.
