Hi guys,
Here's some pictures of my iPod amp I built a year ago. It's based on a very simple circuit based on Toshiba TA7368P IC which works well at a supply range of 2v-9V providing around 1W max. I used 4 x AA 700mAh rechargeable batteries. Everything built inside a telephone surge protection box and the unit can be charged just like a mobile phone. Charger use LM317.
The driver is an 8Ω,3" full range speaker(Panasonic) that has good over all frequency response. However I used an extra tweeter piezo driver(without parallel coil) inside the assembly box for high frequency clarity..
