In this instructable, I will show you how to make a simple headphone adapter for any TV with an audio ouput.
Items you will need:
- TV with an audio output
- RCA to 3.5mm adapter cable
- any FM transmitter with a 3.5mm stereo plug
- any portable FM radio tuner with a headphone jack
To do this, your TV must have an audio output (usually located on the rear AV panel of your TV)
Step 2: RCA to 3.5mm Adapter
You need one these adapter cables to connect the FM transmitter to your TV's audio output.
These things cost about $3.00 USD at RadioShack.
Step 3: FM Transmitter
You need an FM transmitter of any kind, but it must have a 3.5mm stereo plug.
The 3.5mm stereo plug on the FM transmitter will plug into the RCA to 3.5mm adapter cable, which in turn plugs into the audio output of your TV.
You can buy one of these from Amazon.com for under $10.00 USD.
Step 4: Portable FM Radio Tuner
You need a portable FM radio tuner of any kind, as long as it has a headphone jack (they all do, just saying...)
I guess you could use a full size radio with a headphone jack, but that would be pretty bulky...
You can buy one of these from Amazon.com for about $15.00 USD.
Step 5: Diagram
This diagram will show you how to hook everything up. It'll all make sense, it's very simple.
Once you're done connecting everything, just use your portable FM radio to tune into the proper frequency on your FM transmitter.
Use the volume control on your portable FM radio to set the volume to a comfortable level.
There you go! Have fun!
P.S.: You can also do this with a Bluetooth transmitter and Bluetooth headphones. As long as the Bluetooth transmitter has a 3.5mm stereo plug, it's the exact same concept!
