摘要： An electronic device, such as a selective call receiver, includes a housing (302) for the electronic device preferably having a rigid member (304) fixedly integrally attached thereto and extending therefrom, the rigid member constructed to cooperatively connect with a rotatable body (308) and to secure the rotatable body (308) to the housing (302) while allowing the rotatable body (308) to rotate about the rigid member (304), a circuit supporting substrate (301) arranged within the housing (302) coupled thereto, and an alerting device (300) for providing a vibratory alert. The alerting device (300) includes coils (320) on the circuit supporting substrate (301) arranged about the rigid member (304), with each coil (322) capable of being selectively energized. The alerting device (300) also includes a body (308) including magnetic material, preferably including a wedge-shaped mass (314), the body (308) rotatable about the rigid member (304) in a plane substantially parallel to the circuit supporting substrate (301) for directly generating vibrations in the housing (302) via the rigid member (304). Lastly, a selective energizing device (400) selectively energizes the coils (320) to rotate the body (308), to provide the vibratory alert.
