Abstract

One of the problems with today's voice pagers is broadcasting the received message in a private environment, such as, meetings, restaurants, or presentations and distracting other people's attentions. Another problem is the inabil- ity to listen to the message in a noisy environment. The existing solution to these problems is to use an earplug and an earphone jack.

RECESSED EARPHONE WITH AUTOMATIC SELECTION FOR VOICE PAGERS

by Mostafa Hedayatnia

   One of the problems with today's voice pagers is broadcasting the received message in a private environment, such as, meetings, restaurants, or presentations and distracting other people's attentions. Another problem is the inabil- ity to listen to the message in a noisy environment. The existing solution to these problems is to use an earplug and an earphone jack.

   The use of an external earphone poses several problems. First and foremost, the external earphone's is long and very hard to carry and etore for easy accessibility. Secondly, the external earphone is easily misplaced or forgotten in today's active and often hectic life style.

   The proposed solution is a Recessed Earphone [l] with an automatic selection with a retractable wire system [2] inside the housing, as shown in the Figures. Pulling out the earphone from its place would disconnect the speaker [3] and the message could be heard only through the earphone. Different mechanisms can be used for automatic selection of the earphone/speaker such as, a spring loaded switch 141, which has been illustrated in the Figures below. This switch includes a spring [S], and a plunger with conductive [6] and non-conductive [7] segments.
