DIY Wi-Fi audio system

Hello dear readers andthe inhabitants of our site!
Surely many of you often listen to music. But to keep the phone connected to the speakers with wires is not always convenient.
In this article, the author of the YouTube channel Vladimir Natynchik will tell you how to make the speakers wireless.

Many use Bluetooth modules for this, but their range is about 5 meters, and the quality is poor. The author suggests using a system for transmitting and decoding audio over Wi-Fi. The range will be about 50 meters. This homemade product is very easy to manufacture.

Materials
— 
- 5V power supply
- wires
- Insulation tape.

Instruments, used by the author.
- screwdrivers
-, nippers.

Manufacturing process.
So, the author has acquired a small Wi-Fi audio module. It has very good characteristics. The built-in audio card allows you to decode audio with such 24bit / 192kHZ sampling. Moreover, the total distortion is not more than 0.009%. The system also supports the following formats FLAC / AAC + / ALAC / MP3 / APE / WAV. Online music services are also supported. In addition to the board, cables for connecting the signal and power are included.



Vladimir will install it in his columns. You can make a separate module. He disassembles the main column in which the amplifier is installed.



Next, you need to find the power wires after the fuse and switch. They will need to connect a 5 volt power supply.



The author crashed into 220 Volt power wires, soldered them to the power supply. Then I soldered the wire from the receiver kit to the block output.



I carefully insulated the power supply board, and found the inputs of the left and right channels on the board.

Soldered the wires to the signal inputs of the column, connected the connectors to the receiver board.



Before assembling the column, I checked the performance of the system.


To play music from the phone, he installed the Muzo app. The program detected the receiver, and connected to it. Now you can listen to music!





Thanks to Vladimir for the interesting idea of ​​installing the receiver!


All good mood, good luck, and interesting ideas!

Good afternoon, Vladimir! Yes, the idea is very interesting, and the way to solve this idea that you found also deserves respect! In general, everything is clear, for me one detail remained unclear, because you did not specify it. Please inform: are acoustic systems (speakers) connected to each other in the design? I suspect that there is an output (double wire) from the main one (the column where the PSU, UZCh -2 channels, WiFi receiver, etc. blocks are located) for connecting the second column to the UHF! Please confirm or refute my guess. If my suspicion is correct (the columns are connected to each other by a signal wire), please write / state: are there any thoughts / ideas for further improvement of this design. I mean the following connection diagram: the speakers are connected to the gadget via wifi, each speaker (column) has its own built-in power bank and UHF, as well as a receiver of audio and control signals. And each speaker has a single cord - a connection to a variable network (220 volts). Thus, EXPAND MOBILITY AND INDEPENDENCE OF EACH SPEAKER. Really looking forward to your reply.
Sincerely, Alexey

The author has done a good job for newcomers in 2000 Is not it easier to buy a whistle for 100r?
