  • Apparatus, system, and method for managing audio accessories
    Patent number: 12288006
    Abstract: A portable communication system includes a remote speaker microphone (RSM) accessory (102) coupled to a portable radio and further coupled to a secondary audio accessory (SAA) (108). The RSM accessory (102) includes a user interface toggle switch (120) that toggles between a first mode of operation and a second mode of operation. Toggling to the first mode of operation selectively routes receive audio from the portable radio to a speaker (112) of the RSM accessory, while generating and routing a periodic audio artifact from the RSM to the SAA (108) for play out at a speaker (316) of the secondary accessory. The received audio is played out of the RSM speaker (112) in parallel with the periodic audio artifact being played out of the secondary accessory speaker (316).

  • BATTERY MODULE FOR COMMUNICATION DEVICES HAVING AN ACCESSORY INTERFACE
    Publication number: 20160360022
    Abstract: A battery module for a portable communication device having a controller. In one embodiment, the battery module includes a battery accessory interface having a positive terminal, an identifying terminal, and a negative terminal. A voltage regulator is connected to the positive terminal of the battery accessory interface and configured to output a voltage on the positive terminal in response to a control signal. An addressable switch is connected to the identifying terminal of the battery accessory interface. The addressable switch is configured to communicate with the controller and generate the control signal based on input from the controller and the identifying terminal.
