Small loudspeaker options?

I'm looking for a small, lightweight loudspeaker to attach to my quad. Ideally it would have options for uploading audio, that could be triggered via a servo switch.

Anyone know something that would work?

Maybe something like this? There seem to be plenty of similar speakers at Dealextreme.

Wow, that's neat! LOL - how much fun would it be to mount one of these on a heli, and play Flight of the Valkeries at full volume while flying it around the neighborhood on a Saturday afternoon when everyone is out washing their cars, mowing grass, etc.

Even better, have the motors play the Flight of the Valkiries themselves:

Motor Music - Brushless motor controller for Quadrotor UAV (4 min 24 sec)


Brushless and stepper motors can make some nice music, specially if you have more than one.
The second thing I'm going to do when I finish my CNC router is something like this:
CNC Music Factory - MIDI to gcode (2 min 55 sec)

i have an old pair of those


for their size they have a pretty good sound. If you strip them down and power them from the flight battery you could bring them to less that 100g i think.

the UHF LRS receivers that I make have built-in driver to connect speakers or LEDs/igniters.
Microcontroller generates random tones in 14-30kHz band, frequency jumps 2-3times per second, output power is few watts out of cheap($3) ebay tweeter speakers that wegh about 11gram each
Cats and dogs panic when they hearultrasound but dogs get used quick(2-3minutes), I get strong headache , one friend also hates the tones and another friend(old guy) barely hears them.
Pictured tweeters can deliver 4-5watts (not 500!)

Just a minor point: The piece is called "The Ride of the Valkyries"

It would be great to play this from the sailplane...

Enjoy!

Wagner - Die Walküre: "The Ride of the Valkyries" (Boulez) (10 min 54 sec)
