Power control for speaker devices in a wireless media system

A wireless speaker device, comprising:

• a communication circuit;
• an audio processing circuit;
• one or more memories;
• and
• at least one processor each coupled to at least one of the one or more memories and configured to perform operations comprising:
• determining that a host device communicatively coupled to the wireless speaker device via a wireless network is in an active state;
• in response to determining that the host device is in the active state:
• transitioning the wireless speaker device to a connected state;
• transitioning the communication circuit of the wireless speaker device to a first state of the communication circuit;
• and
• transitioning the audio processing circuit of the wireless speaker device to a first state of the audio processing circuit;
• determining that the host device is in an inactive state, wherein determining that the host device is in the inactive state comprises:
• sending at least one data packet to the host device;
• and
• determining that no response to the at least one data packet was received from the host device;
• in response to determining that the host device is in the inactive state:
• transitioning the communication circuit of the wireless speaker device to a second state of the communication circuit that is different than the first state of the communication circuit, wherein the communication circuit consumes less power in the second state of the communication circuit than the first state of the communication circuit;
• and
• transitioning the audio processing circuit of the wireless speaker device to a second state of the audio processing circuit that is different than the first state of the audio processing circuit, wherein the audio processing circuit consumes less power in the second state of the audio processing circuit than the first state of the audio processing circuit.

A non-transitory computer-readable medium having instructions stored thereon that, when executed by at least one computer processor of a wireless speaker device, cause the at least one computer processor to perform operations comprising:

• determining that a host device communicatively coupled to the wireless speaker device via a wireless network is in an active state;
• in response to determining that the host device is in the active state:
• transitioning the wireless speaker device to a connected state;
• transitioning a communication circuit of the wireless speaker device to a first state of the communication circuit;
• and
• transitioning an audio processing circuit of the wireless speaker device to a first state of the audio processing circuit;
• determining that the host device is in an inactive state, wherein determining that the host device is in the inactive state comprises:
• sending at least one data packet to the host device;
• and
• determining that no response to the at least one data packet was received from the host device;
• in response to determining that the host device is in the inactive state:
• transitioning the communication circuit of the wireless speaker device to a second state of the communication circuit that is different than the first state of the communication circuit, wherein the communication circuit consumes less power in the second state of the communication circuit than the first state of the communication circuit;
• and
• transitioning the audio processing circuit of the wireless speaker device to a second state of the audio processing circuit that is different than the first state of the audio processing circuit, wherein the audio processing circuit consumes less power in the second state of the audio processing circuit than the first state of the audio processing circuit.
