Fold switch
The detection of the position of the fold is made through a Hall sensor and an IHF magnet. The magnet is
positioned on the top board.
When the fold is opened, the applied magnetic field is high. This is sensed by an internal switch, also
connected to GND. When the fold is closed, the Hall sensor is fluxed by magnetic field.

Audio concept
The functional core of the audio hardware is built around RAP3GS and N2200 AVILMA.
N2200 provides an interface for the transducers and the AV connector.
There are three audio transducers:
• 2 dynamic speakers (IHF and earpiece)
• 1 microphone module
N2200 also provides an output for the vibra motor.
All external audio accessories are connected to the specific audio connector.
