Selective call receiver having audible and tactile alerts

An apparatus comprising:

• a housing;
• a flexible member within the housing and coupled thereto;
• a moving member coupled to the flexible member for movement about an equilibrium position;
• and
• piezo-electric actuator means coupled to the flexible member for causing the flexible member to flex thereby causing the moving member to move, the flexible member flexing at a first frequency or a second frequency for causing the moving member to move at the respective first and second frequency to generate an audible alert and a sub-audible or tactile alert, respectively, the movement at the second frequency being transferred to the housing for generating the sub-audible or tactile alert.

A selective call receiver comprising:

• receiver means for receiving a message;
• controller means coupled to the receiver means for presenting the message, the controller means also initiates an alert signal;
• and
• alert means coupled to the controller means for presenting one of an audible alert or a sub-audible or tactile alert in response to the alert signal, the alert means further comprising:
• a housing;
• a flexible member within the housing and coupled thereto;
• a moving member coupled to the flexible member for movement about an equilibrium position, the moving member including a permanent magnet;
• a diaphragm coupled to the moving member and located within the housing for generating the audible alert in response to movement of the moving member;
• and
• actuator means coupled to the moving member for causing the moving member to move at a first frequency for generating the audible alert and at a second frequency for generating the sub-audible or tactile alert, the actuator means including electromagnet means for causing the permanent magnet and the moving member to move, the movement at the second frequency being substantially transferred to the housing for generating the sub-audible or tactile alert.
