Wireless Speaker That Connects in 0.0000000001 Seconds!

For those who feel like pairing wireless speakers can be really time consuming, you need to make this wireless speaker that connects in 0.000000000001 seconds (basically instantly). Although it doesn't use Bluetooth or WiFi, it works for every smartphone, tablet, etc. To build this system, you will need an audio amplifier; I used a PAM 8403 (it's very cheap), transformer coil, and any speakers (your choice)!

Let's get started! Beforehand, I recommend watching the video above so you will know what I am talking about!

Step 1: What's The Problem With Bluetooth?

DELAY!

Pairing a wireless piece of headphones to a smartphone takes a lot of time. And sometimes there's a weird pitch shift, and latency is always a big NO-NO! You also have to recharge the small battery.

Step 2: How It Connects In 0.000000001 Seconds!

Every digital wireless system has delay due to various factors like medium, range, processing, etc. But this delay can be reduced by use of analog transmission methods.

This system works similarly to an electrical transformer; the supplied high voltage is converted into a magnetic field. This magnetic flux gets induced onto the secondary coil and generates voltages in proportion to the coil's turns ratio.

The coil inside the smartphone speakers acts as a primary coil and our external coil receives the signals. This signal is very small, so we need an amplifier to be able to drive bigger speakers. You can connect ear buds or loudspeakers, and similarly can extract audio from any speaker source, e.g., smartphone, tablet, tv, as long as it has speakers! And it doesn't require pairing since it's analog and just does the job of re- amplification; it connect's in 0.0000000001 seconds!

Step 3: How To Make

Parts you will need to buy:

• Winding Wire

• PAM8403

• Speakers

1. You will need a coil which you can easily get from old power supply transformers, or just wind it yourself.

2. To boost the small audio a signal amplifier is required. I used a class D PAM8403, but any amplifier will work fine, even your home theater (just make sure volume is low)!

3. Connect the speakers at output and bridge the right and left channel input. Connect the coil and supply the voltage, and it's ready!

4. You may need to put a capacitor in parallel with the voltage source, because this amplifier will draw more current for higher amplitudes. So to keep it running continuously, add a 2200uf capacitor.

Step 4: Can You Get Superpowers With It?

Yeah! If someone challenged you to guess the music they're listening to, you can guess the music by simply holding the coil over earphones and listening to the music clearly!

There's even more!!! Listening to electromagnetic waves is a whole new world. You may never have experienced this but might be familiar with interference created by calls with speakers! Just try scanning different parts of your smartphone and you may be able to listen to what's going on inside the CPU, RAM, network chips, etc.
