I'm looking to use a single small 2W 20mm x 40mm rectanglular speaker (http://www.maplin.co.uk/p/2w-mylar-and- ... 40mm-n99fu
) in a robot I'm building. I was wondering if someone could point me in the right direction for a amplifier to use- amplifying the audio jack output from the Pi to a reasonable level. I'm looking for something reasonably good quality, able to output speech (probably espeak) and recorded sounds from Sonic Pi, possibly also music though this is not the aim of the robot. I would like it to be as small as possible really as space is somewhat limited, and preferably less than £10.
I've found this:

but as I have no experiance with amplifiers, I don't know if it would be a good choice.
Thank you very much, forumgoers!
