RADIO SELECTIVE CALLING RECEIVER

摘要

PURPOSE:To make the size of the receiver small, to realize thin profile and to exclude noise sound due to mechanical vibration by employing a sound of non-audible frequency for a reception notice means in the radio selective calling receiver. CONSTITUTION:A carrier of a receiver uses a switch 9 to select a reception notice means comprising a sounder 8 and when the carrier carries the receiver, a bottom 102 of the receiver is in close contact with the body of the carrier and when the receiver receives a call arrived to itself, the sounder 8 is vibrated at a non-audible frequency and the air vibration transmits through slits 103 to provide sound wave vibration and the carrier of the receiver senses the reception of the call.
