Acoustics troubleshooting
Introduction to acoustics troubleshooting
Acoustics design ensures that the sound is detected correctly with a microphone and properly radiated to
the outside of the device by the speaker. The acoustics of the phone include three basic systems: earpiece,
stereo integrated handsfree (IHF) and a microphone (for noise cancelling).
The sound reproduced from the earpiece readiates through a single hole on the front cover (A-cover). The
sound reproduced from the IHF speaker radiates from the sound holes located on the lower left and right
side respectively, found in the bottom part of the phone.
For a correct functionality of the phone, all sound holes must be always open. When the phone is used, care
must be taken not to close any of those holes with a hand or fingers. The phone should be dry and clean,
and no objects must be located in such a way that they close any of the holes.
