A distributed network system may include a shared communication bus that operates in accordance with a communication protocol and a plurality of devices coupled to the shared communication bus. The communication protocol may define periods of time and an order by which each of the plurality of devices actively transmit data on the shared communication bus such that only one of the plurality of devices actively transmits data on the shared communication bus at a time to a remaining number of the plurality of devices through the shared communication bus. When the remaining number of the plurality of devices are not actively transmitting data, the remaining number of the plurality of devices may receive data via the shared communication bus so that bi-directional communication is established among the plurality of devices on the shared communication bus.

Multi-device synchronization of devices

In accordance with systems and methods of the present disclosure, an audio device may include an electrical terminal, an audio circuit, and a transducer load detection circuit. The electrical terminal may couple a transducer device to the audio device. The audio circuit may generate an analog audio signal, wherein the analog audio signal is coupled to the electrical terminal. The transducer load detection circuit may detect a load impedance of the transducer device when the transducer device is coupled to the audio device from characteristics measured at the electrical terminal.
