Abstract: An audio appliance includes an oscillatable diaphragm, a first heat-dissipation unit, a second heat-dissipation unit, and a control unit. The first heat-dissipation unit dissipates heat at a first rate and the second heat-dissipation unit dissipates heat at a second rate. The control unit can receive an indication of a temperature of the first heat-dissipation unit and an indication of a temperature of the second heat-dissipation unit. The control unit provides oscillation control of the oscillatable diaphragm to maintain the temperature of the first heat-dissipation unit below a first threshold and/or to maintain the temperature of the second heat-dissipation unit below a second threshold. The control unit can provide the oscillation control responsive to each of the indication of the temperature of the first heat-dissipation unit and the indication of the temperature of the second heat-dissipation unit exceeding a respective threshold.

Abstract: Methods and systems provide control of media synchronization using time stamp pairs. In an embodiment, a first device may request a time stamp from a second device. The first device may determine any de-synchronization between the first and second devices based on the requested time stamp and characteristics of the request. The first device may define a rate scalar based on the determined de-synchronization. A sample rate conversion may be performed for the first device based on the rate scalar such that the outputs of the first device and the second device are synchronized.

Abstract: In one embodiment, a device-side audio handling input/output unit (DIO) of a microphone writes audio data generated by the microphone into a ring buffer. A system-side audio handling I/O unit (SIO) receives a request from a software program to consume past audio data from the ring buffer. The SIO provides the past audio data from the ring buffer to the software program. Other embodiments are also described and claimed.

Abstract: Techniques are disclosed for transmitting an announcement to one or more devices. In one example, a first device receives a first message that includes an announcement, the announcement associated with a voice that spoke the announcement. The first device may determine the announcement from the first message, and then identify one or more devices for receiving the announcement. The one or more devices may have a particular device type of a plurality of different device types comprising at least a mobile device. The first device may determine a network path through which a second message is transmitted based at least in part on the location of a second device. In accordance with a determination that the second device is located within a local area network associated with a home environment, the first device transmits the second message over the local area network. In accordance with a determination that the second device is located away from a local area network associated with a home environment, the first device transmits the second message over the wide area network.

Abstract: In one aspect a device-side audio handling input/output unit (DIO) of a hardware device writes audio data generated by the hardware device within a ring buffer. An input provided by a user for activation of a software program is received, and a notification that the software program is ready to accept the audio data is generated. A system-side audio handling input/output unit (SIO) additionally provides past audio data from the ring buffer to the software program. Other aspects also are described.

Abstract: Method of audio power reduction and thermal mitigation using psychoacoustic techniques starts by receiving a decoded audio signal in a reproduction system. Decoded audio signal is a signal that is decompressed and to be played back by a speaker. A masking curve is generated based on psychoacoustic models and the decoded audio signal. The masking curve is applied to the decoded audio signal to remove unheard frequencies and to generate a power-reduced audio signal. Other embodiments are also described.
