Is Building a Radio Transmitter for Wireless Earphones a Feasible Solution?

[daniel_i_l]

I wanted to get wireless (bluetooth) earphones for my mp3 player but when I checked I found that they were way out of my price range (bluetooth earphones for phones with bluetooth are relatively cheep, but for a regular mp3 player they're expensive ~ 200 dollars).
So I had an idea: I can make a radio transmitter that plugs into where my earphones normally plug in and make it transmit the music at some AM frequency up to about a meter - and then make a tiny radio receiver for that frequency only which I connect to some earphones. The I just have to plug the transmitter into the mp3 and the music will be transmitted to the earphones.
Now, I've never actually built a transmitter before (just the receiver) though I'm pretty sure I know how. So my question is - do you think that this is a feasible solution to the problem? Would it be possible to build a transmitter that didn't substantially lower the sound quality? Are there better solutions to this problem?
Thanks.

How about some fm radio headphones and a fm modulator like they sell for playing mp3's in your car. It would all be < $50 I would think.

Hello,

Thank you for sharing your idea for building wireless earphones. It is always exciting to see individuals coming up with creative solutions to everyday problems.

In terms of feasibility, your idea could potentially work. However, there are a few factors to consider. First, the range of the transmitter may not be as far as you anticipate. AM frequencies typically have a shorter range compared to Bluetooth technology, so you may need to be within a few feet of the transmitter for it to work effectively.

Additionally, you mentioned that you have never built a transmitter before. Building a functioning transmitter can be a complex task, and it is important to understand the technical aspects and safety precautions involved. I recommend doing thorough research and perhaps consulting with an expert in this field before attempting to build one on your own.

Regarding sound quality, it is possible that the transmitter could affect the sound quality of the music. This is because AM frequencies are more susceptible to interference and can pick up other signals, leading to distortion. However, with proper design and shielding, it may be possible to minimize this impact.

There are other solutions to your problem, such as purchasing a Bluetooth adapter for your MP3 player or investing in a more affordable pair of Bluetooth earphones. It may also be worth considering the long-term cost and effort of building and maintaining a transmitter compared to purchasing a ready-made solution.

Overall, your idea shows great creativity and problem-solving skills. However, it is important to thoroughly research and understand the technical aspects before attempting to build a transmitter. I wish you the best of luck with your project.

Best regards,
