Abstract
A mobile communication device includes first and second housing sections movably connected so as to move relative to one another between open and closed positions. The first and second housing sections each include protected surfaces that overlap when the first and second housing sections are in the open position. A distributed mode speaker is disposed on one of the protected surfaces to protect the distributed mode speaker from damage.
