Post by thread:[EE] mini speaker

Im looking for miniature speakers, such as what might fit into a keyfob. Granted I've told my client...your not going to get much out of them being that small but they want me to look... Anyone have experience with really tiny ones?

I've played with some tiny speakers intended for use in cell-phones but they appear to require an acoustic resonator to have any decent volume. I quit playing with them after I found that out. On the other hand - some cell-phone speakers DO get pretty loud. Might be worth checking out. dwayne -- Dwayne Reid <spam_OUTdwaynerTakeThisOuTplanet.eon.net> Trinity Electronics Systems Ltd Edmonton, AB, CANADA (780) 489-3199 voice (780) 487-6397 fax http://www.trinity-electronics.com Custom Electronics Design and Manufacturing

(plastic cone) (Best quality, but a bit larger than common keyfobs). Larger headphone drivers used as speakers in novelty keyfob gadgets (not the in ear bud type). (plastic cone). Poor o/p The possibly ceramic type used in Mobile phones. The larger diameter ceramic disc in novelty keyfobs and greeting card tunes. Most efficient, but limited and erratic frequency response with resonances.
