Abstract
An apparatus (100) including two housings and a piezoelectric transducer is disclosed. The apparatus may include a first housing (110), a hinge (115) coupled to the first housing, and a second housing (140) coupled the first housing via the hinge. The first housing can have a closed position when the first housing is substantially adjacent to the second housing and the first housing can have an open position when a portion of the first housing is substantially away from the second housing. The apparatus can also include a first piezoelectric element (130) coupled to the second housing where the first piezoelectric element can be substantially in contact with the first housing when the first housing is in the closed position. The apparatus can further include a user interface (140) coupled to the second housing and a controller (150) coupled to the first piezoelectric element and the user interface. The controller can drive the first piezoelectric element to cause the first housing to vibrate against the second housing when the first housing is in the closed position. The controller can also drive the first piezoelectric element to provide tactile feedback in response to user activa…
