Veho 360 Speaker as replacement for Piezo

John Kauffman

I teach retired guys and many can't hear well. That dilutes the FREQOUT part of the course.
I'd like to use the Veho 360 Speaker to replace the piezo.
I know this is not just a swap-out. What do I need between a STAMP pin sending a FREQOUT and the Veho 360 Speaker 1/8 jack in? I'm guessing an audio amp on a single chip, but not sure at all.

(Don't say "switch to Prop BOE" - that is coming next year! )

Thanks.

Veho is an amplified speaker, powered by an internal LiPo, recharged via USB. Plenty loud, so you won't need any more amplification. Probably just an electrolytic cap connecting the BS2 pin to the Veho. BTW, if you need lots of them, there are cheap Veho clones from CEbay China: http://www.ebay.com/itm/Mini-Hamburger-Portable-3-5MM-Speaker-for-iPod-iPhone-/320627713681?pt=Other_MP3_Player_Accessories&hash=item4aa6e6a691
