Hi,
I found some spearkers my brother wasn't using for his w810i sony walkman phone, they attached to the phone via tha phones standard connection. There was really good sound from them for the size and I thought it would be cool if I could use them on my ipod/discman etc.
So I got an old pair of cheap headphones, cut off the wires, cut off the connection to the phone speakers, and soldered the wires together. To my joy it worked, I have never done anything like this before, not even soldered anything!
But the reason I am posting is the sound is nowhere as loud as it was with the phone.
Could anybody give any suggestions how I can get the sound output louder? Is it possible the phone was providing power/amplification to the speakers somehow?
These are the speakers and phone:

Thanks,

Really Ipods etc are only intended to drive headphones. If you want to use speakers, you need powered ones with built in amplifiers designed for such devices. The original Sony would have had a higher output, enabling it to drive an un-powered speakers directly. Sorry no amount of playing around will make this setup any louder. You live and learn!. Keep at it.

I don't think the phone will have enough power to handle the speakers.

One question:

Do you need batteries to operate the speakers ?

If yes, most probably your connections are not correct.

It will be helpful if you can post a drawing of what you have made.

Added after 3 minutes:

Oh, my mistake.

I did not understand your post the first time.

If you say there is sound but not too loud, then GrandAlf is correct (Sorry)

Anyway it will be helpful if you post a picture of your connections.


Cheers.
 

Well what I have is just soldered 2 wires together so there's no point showing a pic of that! But I'll show a pic of the original connection circuit, which is what was replaced with a headphone jack.
It has capacitors, I think I may have seen somewhere they can amplify sound is that right?
In the pic the 4 connections at the top are where the speaker wire originally attached.
 

The capacitors are for DC blocking, just allows AC speaker signal through. This circuit will NOT amplify. As stated before you will need battery or mains amplified speakers if you want to go in that direction.
