Audio concept
Audio HW architecture
The functional core of the audio hardware is built around two ASIC’s: Cellular Modem ASIC D2800 and the
mixed signal EM ASIC N2200.
There are four audio transducers:
• Dynamic earpiece (part of UI/Slide module)
• 2 Dynamic speakers
• Electret microphone
In addition to the audio transducers, N2200 also provides an output for the dynamic Vibra component. All
galvanic audio accessories are connected to the AV-connector. Bluetooth audio module, that is connected to
Cellular Modem ASIC D2800 supports Bluetooth audio functionality. For some audio applications, part of the
processing is done on application processor ASIC D4800, for example for Music Player.
