Unitized housing for silent and tone pager alerting system

摘要

A housing for an alerting system within a selective call radio receiver exhibits substantial space saving characteristics by incorporating both a low profile vibrator motor for silent alerting and a tone generator for audio alerting. The housing comprises a rigid material defining first and second chambers adjacent and separated by a common wall of the housing, the first chamber containing the low profile vibrating motor, the second chamber containing the tone generator, the housing defining a first port therein for omitting an audio tone from the second chamber and at least one other port therein for providing power to the low profile vibrating motor and the tone generator.
