Portable Bluetooth speakers for 20 bucks and 30 minutes. Do it yourself
The idea of having portable Bluetooth acoustics has long given me no peace. However, the price / quality ratio still did not come to a reasonable, and still leaves much to be desired. There are some excellent models on the market that deserve to be bought, such as the JBL Voyager portable speaker. True, the price here is too high - about $ 220. But I don’t really want to overpay only for the eminent brand.

Getting started.
Short plan:
Selection of components.
1. One of the most important characteristics of portable speakers, in my opinion, are size and weight. Based on these mandatory criteria, we will look for the most popular and inexpensive model of multimedia acoustics. Ok, google) After analyzing the characteristics, the choice fell on the Sven 315 speakers. For a price of about $ 8, we get very compact speakers with high-quality multimedia sound. A huge number of positive reviews confirm this. ( http://market.yandex.by/product/6226111/reviews?hid=91107&track=tabs )
Admire, here they are ( http://www.sven.fi/ru/catalog/multimedia_2.0/315.htm )
Specifications:
2. The next component is the Bluetooth module. A cursory examination of the sites www.dx.com and www.aliexpress.com found suitable modules for $ 6-7 ( http://www.dx.com/s/bluetooth+audio+receiver+module ). However, an ad on the local flea market site suddenly found an option that could be picked up as early as tomorrow for $ 10. I didn’t really want to wait for the parcels from the Chinese friends, and I purchased what was. My version ( Bluetooth Music Receiver Adapter Audio Adapter Audio Stereo a2dp 30 pin )
This adapter is designed to connect to legacy docking stations with a 30-pin Apple connector. To pair newer i-gadgets (with a lightning connector) or Android gadgets via Bluetooth.
3. And the last component is a lithium-ion battery. Everything is simple here. Since the power of our speakers comes from a standard USB cable (5V), then we take any portable charger with USB output and a capacity for how much money.

Here the more battery power, the longer the music plays.
Assembly.
First of all, we need to parse the SVEN 315. I used the video instruction.
Then we disassemble the Bluetooth module, remove the card. This is only needed for my specific 30-pin model (for boards ordered from http://www.dx.com/s/bluetooth+audio+receiver+module this is not required).
Having disassembled the column, shorten the audio input wire and solder it to the Bluetooth module. We also branch and solder + 5v power from USB.
Fasten the inside with all thermoplastic glue so that nothing dangles.
After installation can be checked. We connect the speakers via USB to a portable charger. And we pair with the phone.
That's all.
We have turned out great budget portable speakers with which you can safely go on a picnic with friends.
