5.00 Ipod Amplifier





Introduction: 5.00 Ipod Amplifier

5.00 IPOD (portable audio whatever) Amplifier.

I found these at Big lots and picked up a couple, they are 5.00 and you can remove the portable battery powered amplifier to use on whatever you choose.

It runs off 4 AAA Batteries and you can make the lil battery powered speakers sound like a lil boom box.

Step 1:

Inside there is a lil amp ran to a single speaker. Its screwed in from behind.

Step 2:

Remove the amp:

Carefully cut around the amp, once you can get your hand behind it you can unscrew it.

You also need to cut the wire going to the speaker.

The 1st time I did this I really over cut, you can just go around the amp and then have a descent carry case left over.

Be careful not to cut the wire closer then you want to, it runs up in the case. (up and left)

Step 3:

I used a 3.5mm Stereo Plug and ran the wire the formally went to the speaker and soldered it to a 3.5mm Stereo Plug to run to portable speakers.

I also just rolled up the other wire that will run to the IPOD, it has the green shrink wrap on it.

There is a "share port" but it is not amplified.

The unit runs off 4 AAA Batteries.

Step 4:

I have a lil case that holds my IPOD and the amp together, I have the speaker out so I can run it where its needed.
On my bicycle I hang it from the mirror and its a great lil wanna be boombox.

Step 5:

Ive made 2 now, the 2nd just to clean it up and for 5.00 figured a back up is good. I saw similar units at Frys starting at 50.00. And I think Frys is usually the cheaper option.

    Hey there! I bought the same item at Big Lots and made it into an amplifier. Works great when cutting the grass listening to my mp3 player!

    i can buy 5.00 $ amplifier  in the internet ????

    I tried using a microphone as an input to be amped and it didn't work. Anyone know why?

    Microphones only push a few milivolts, these amps expect at least 300mV from what is essentially a line or headphone output.

    This amplifier is meant to boost a signal thats already somewhat strong. A microphone provides absolutely no signal at all. You need to connect it to a preamp to make a signal, then connect it to another amp to make it loud.

    Not sure that Ill explain correct or even am correct ... I think something would need to "push" that initial sound from the Mic, for what Im doing the IPOD is powered and its pushing the sound. This is added inline to boost what is already there. If there is no initial push I think it cant power the mic.

     how loud would this amp being if I hooked it up to a car speaker?

    It depends on the speaker's specifications (particularly the sensitivity, or SPL). 95dB SPL is twice as loud as 85dB SPL. Most car speakers I've seen don't specify their sensitivity.

    How many speakers can u plug in?

    As many as you want, but that won't make it give you more sound (maybe the illusion of it), and if you load the amp down too much with too many speakers (dropping the load impedance too far), you could damage the amplifier if it doesn't have overload protection (usually shutdown).

    For more sound, you need to push more power (higher output amp) or more sensitive speakers. Pushing 1W of power into a 93 dB 1W/1m SPL (sound pressure level)speaker would sound about the same as pushing 10W of power into a 83 dB 1W/1m SPL speaker (of the same physical cone size).

    I have noticed that a smaller speaker will sound louder when it really isn't, due to the harsher sound it makes compared to a larger speaker which would be heard better in a greater area without actually sounding loud
