1. Display apparatus, comprising:
- a first elongate member;
a display member;
means supporting said first elongate member and said display member for relative movement with respect to one another, in response to an external perturbation, from a stable substantially vertical orientation to an unstable activate orientation;
an electrically responsive sound transducer; and
circuit means, responsive to relative movement of said first elongate and display members to said unstable activate orientation, for energizing said transducer to produce audible sound.

Abstract
Transducer apparatus (10) responsive to external perturbations is disclosed having an electrically responsive transducer circuit (12) energized when a display member (18) and an elongate member (20) move from a gravity determined quiescent orientation (30A) therebetween to an external perturbation driven activate orientation (30B therebetween. In various embodiments, the members are respectively responsive to air movement and acceleration. In one embodiment, the elongate member carries a first electrical contact (21) to abut a second electrical contact (22) carried by the display member.
