Apparatus including two housings and a piezoelectric transducer

An apparatus comprising:

• a first housing;
• a speaker coupled to the first housing;
• a hinge coupled to the first housing, the hinge including a cam mechanism;
• a second housing coupled the first housing via the hinge, wherein the first housing has a closed position when the first housing is substantially adjacent to the second housing and the first housing has an open position when a portion of the first housing is substantially away from the second housing;
• a microphone coupled to the second housing;
• a first piezoelectric element coupled to the second housing, wherein the first piezoelectric element is substantially in contact with the first housing when the first housing is in the closed position;
• a user interface coupled to the second housing;
• and
• a controller coupled to the first piezoelectric element and the user interface, the controller configured to drive the piezoelectric element to cause the first housing to vibrate against the second housing when the first housing is in the closed position and the controller is configured to drive the piezoelectric element to provide tactile feedback in response to user activation of the user interface.
