Abstract
An alerting device for a selective call receiver (100) efficiently generates a tactile vibration alert and an audible alert simultaneously. A vibrator motor (15) includes a modified eccentric weight (14) which becomes an efficient air mover upon being rotated about the axis (13). Integral to the eccentric weight (14) is a sound producing orifice (28). The orifice (28) generates an audible alert in response to air moving either across or through the orifice (28). The audible alert can be selectively enabled by the selective call receiver user, or by the message type received.
