I think it's a speaker.  See if you get a little click if you put an
ohmmeter across the terminals.

I was imagining a label on it, saying "Der Loudenspeaker ist nicht
fur gefingerpoken."  Loosely translated that would mean "no user
serviceable parts inside."

Subject: [AMRadio] What's A "Isophon Lautsprecher"?


Hmmm...What I have here is 2 small packages about 3 inches square
and 1 inch deep. The label on each one says "Isophon Lautsprecher St
HB 7  S228". Inside each package is a 1/2 inch thick bakelite and
aluminum assembly with a grille on one side and 2 wires on the
other. The label on the back of each of these is the same as on the
package. Molded into the back of each one is "Made in Germany".
Hmmm...it doesn't say "made in West Germany" and it is too old to be
made in post-USSR-breakup Germany. So I conclude that these were
made in pre-war Nazi Deutschland.

Anyone? Any Guesses? Any referrals to someone who might know? These
were found in an estate in a paper Cameradio bag on which was
written "electro-static".

Any that's all the clues I've got to give you. Any help appreciated.
Thanks.
