First of all, it's not an audiophile, it's interesting to spend less than 10 yuan to do it, pass the time.
The finished product effect has not yet increased the battery module
Component module 1: 4 euros 3W small speaker, bought on a treasure, can be purchased with a red envelope, an average of 1.5 yuan for a speaker, because my ears are more sensitive, I don't like loud sounds, so choose a small power.
You can buy one that works well, and I'm also transitioning
Component module two: Bluetooth module, you can choose MH38 5W+5W small power amplifier board, buy this is to consider changing to a larger speaker in the later stage, you can take a look, the price is OK, about 5/6 yuan, with red envelopes can be lower!
Component module three: cavity, I considered this, and then I chose a single-hole button box, which is quite thick, the key is that it didn't cost money, haha!
APT's button box is really thick, and it's not cheap to buy, so it's good to use it as a cavity
The box is really good, but it's too difficult to open the hole, and there is no tool to take advantage of, so it can only be broken a little bit, and the back equipment is equipped to buy decorative stickers and metal mesh decorations, so it is understandable that it is difficult to open!
Start the stationary assembly:
Glue and seal it, otherwise it will be too ugly
Install the Bluetooth board, close the cover, the glue gun is really a good thing, just stick it directly.
This hole is very ugly, let's decorate it later
The first part has been completed, repeat the second part.
