Nice forum folks. I'm glad to of found a resource like this.
Please excuse my lack of technical understanding within this post... allow me to explain:
I have a small active speaker. Its size is only about 0.3Lt.
Here are the specs that are screen printed on the back:
Generic brand, Made in China.
Inputs: 5.0VDC & 3.5mm Stereo Jack.
Output: 3.7v = 1000mAh (the only actual output is the speaker)
Li-ion Fixed Batt inside.
The original battery only lasted 20 mins and it was not possible to charge and play music at the same time.
I then replaced the original battery with a soldered-in Nokia cellphone battery. I'm sure some tiny circuit board glued to the battery got lost in the swap somehow.
Now, the sounds just cuts out when I put any voltage into the audio mini-jack (specifically: low frequency transients cause the cut outs).
What I want to do is fix it so that it just works like it should!
My questions are;
1. Must I replace the hacked-in Nokia (750mAh-ish) battery with 1000mAh or more?
2. Does it sound like I've lost a capacitor when I replaced the old battery?
3. What (easily at hand) cap / diode / transistor must I use to fix it properly and what would the circuit look like (presume it's needed between the batt & amp) ?
4. Can I just remove the battery and rely on the 5VDC wallwart?
Please Help!
