Abstract

An accessory for mounting on the receiver of a personal paging system. The receiver is normally worn below ear level and the accessory increases the sound of the paging signals reaching ear level.

Claims

1. An accessory for a personal paging device adapted to be worn below ear level by a user, said device having a case of generally rectangular cross section containing radio receiving apparatus including a speaker for emitting an audio paging signal and a grille in an upper part of an outer side wall of the case through which the signal is emitted, said accessory comprising an open ended member of generally rectangular cross section slidably fitting over said case, the lower end of said member fitting tightly against the said outer side wall below and adjacent said grille, and said member having a wall opposite and spaced outwardly from said grille diverging outwardly and upwardly at an acute angle to said outer side wall for increasing the intensity of the sound at ear level of the paging signals emitted from the upper end of said accessory.

2. An accessory for a personal paging device adapted to be worn below ear level by a user, said device having a case of generally rectangular cross section containing radio receiving apparatus including a speaker for emitting an audio paging signal and a grille in an upper part of an outer side wall of the case through which the signal is emitted, said accessory comprising an open ended member of generally rectangular cross section slidably fitting over said case, the lower end of said member fitting tightly against the said outer side wall below and adjacent said grille, and said member having an open topped upper section opposite and offset outwardly from said grille and diverging upwardly at an acute angle for increasing the intensity of the sound at ear level of the paging signals emitted from the upper end of said accessory.
