摘要
A selective call receiver includes a vibrator (206) for generating alerts. The vibrator (206) includes a housing (402), a flexible member (2) within the housing (402) and coupled thereto, and a moving member (404) coupled to the flexible member (2) for movement about an equilibrium position, the moving member (404) including a permanent magnet (410). An actuator includes an electromagnet (412) for causing the permanent magnet (410) and the moving member (404) to move at a first frequency for generating an audible alert and at a second frequency for generating a sub-audible or tactile alert. The movement at the second frequency is substantially transferred to the housing (402) for generating the sub- audible or tactile alert.
