Now it is your choice where you want to cut the cord. Just be sure that there is some cord left before the headphone jack so as to be sure that there won't be any problem with the signal.

Step 3: The End

Remember that before you make fun of someone that is not a native English speaker.

its kind of strange that manufacturers would choose to use the headphones as the fm antenna and not the big grounding contacts on the board, the only problem with this is if you have a phone or mp3 player that switches from speaker to headphones when a jack is inserted, in which case this would cancel out the sound.

nice and simple though! i give it 5*s.

the headphone cord doesn't pick up anything, the antenna is inside of your mp3 player picks it up, and i pods, surprisingly enough, dosent have any internal radio

It may be that way but when I cut all the headphone cord from a pair of apple headphones the signal was lost.

The Iphone headphones have a different mini-phono jack than regular headphones.

Iphone uses a FOUR connector jack, where as normal headphones use a 3-connector.

You'll have the same problem using the jack from some of the older wired cell-phone headsets.
Basically, you end up either NOT making contact, or making overlapping contact, inside the jack...

Likewise, if you try to use normal headphones on an iphone/ipod... you'll end up with sound out of one ear only, usually.

Is this a joke?

arv_christos (author)rimar20002011-07-13

Is there any specific reason why this ible could be a joke?

Because a piece of cord in the earplug does not converts an audio signal to RF signal. Your instructables was named "FM transmiter..." at first. Now you changed the tittle, that change changes the thing. Pardon if I offendded you.

The Android "FM RADIO" application won't turn on, without earphones plugged in.

This is partially because it uses the headphone cord to act as a secondary FM antenna(the cellular antenna is the "primary" but is low gain, because of the size, and the fact that FM is on the very edge of the frequency range it was designed to receive)

I WOULD suggest a longer length of cord though. The longer the dangle, the better the reception... up to 0.92 meters in length(for 101.9FM).
That's the 5/8ths wavelength measure... optimal for FM reception.

I think you mean FM receiver

Bongmaster (author)randofo2011-07-13

to be fully correct he's making a FM antenna

arv_christos (author)randofo2011-07-13

Thanks for the correction. You know I am from greece and I am not a native english speaker
