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..
Audioguru.is right (as usual) there is much you can do to improve the sound quality.However I 'm NOT critisising your work.I've built a stereo amp for mp3 playback (at the moment I;m using it to play via the 2 rear speakers in my Volvo)allthough Uncle scrooge(my best friend) doesn't like the TDA 2003 IC,I've used them in my amp.& the sound quality is excellent,plus it does not need a pre-amp.The signal from the mp3 player is more than adequate for satisfactory results.you can populate the components on a small peice of strip board,& use a 2200uF Cap to save space.If you want the circuit let me know. tblo163
Hi Transistor,
I think you posted some "music" from India. It had no bass frequencies.
Your music is very different from our music. Even the instruments are very different.
