Is an EARPHONE JACK the same as EXTERNAL SPEAKER jack???

[[email protected]]

I have a small metal outdoor speaker that used to be used for paging
and general voice purposes. I was wondering if I plugged it into an
EARPHONE jack of a radio, tape player etc... as long as the jack sizes
were in sync if the speaker would work.

In other words, is an EARPHONE jack basically the same thing as an
EXTERNAL SPEAKER jack?

Thanks in advance

Usually (but not always) an "earphone" jack *IS* an "external speaker"
jack with a level-limiting resistor attached to it, while a true
"external speaker" jack is a straight shot from the final stage of the
amplifier. Which means that if you've got the level-limited type of
earphone jack *AND* an external speaker jack, the "speaker" one is going
to give you a louder output than the earphone jack at the same volume
setting on the knob.

Don't confuse either of them with a "line out" jack. A line out won't
drive a speaker (of any size) worth anything, since it's a fixed (and
very low) level output intended to be piped to at least one more
amplifier stage before hitting a speaker.
