<p>A percussion output device (10) is assembled from a shell (12) having an open end (12b) and a closed end (12a) that provides an inert striking plate and that defines a conduit (24) therein. A mallet member such as a ball (26) is disposed in the conduit (24) in the shell (12) near the open end (12b) of the shell (12). The ball (26) can travel through the conduit (24) to the closed end (12a). An impeller such as the signal-emitting end of a length of shock tube (14) is disposed in the open end (12b) of the shell (12). A signal emitted from the impeller, e.g., from shock tube (14), impels the ball (26) towards the closed end (12a), generating a percussion output that can be used to initiate percussion-sensitive devices. The device (10) is self-contained in that no projectile or explosive or pyrotechnic signal is released from the shell (12).</p> |
