Hello Friends!!
In this instructables I'm going to make a portable as well as a very cheap bluetooth speaker. I had an 1 dollar speaker laying around with dead battery and a not working speaker, so I thought it'll be best to salvage parts from it and make something similar. The module was perfect so here I'm using it make this fun weekend project.

Supplies

So here is the list of everything we need to make this tiny speaker.(All the links are only for indian users. If you're from other countries then copy paste the components name in your search engine to find the best match. )
1. Cheap bluetooth speaker for module ( recycle or buy from here https://www.amazon.in/dp/B092SSKD37/ref=cm_sw_r_cp_apa_glt_fabc_E75NTEG7M83BFKP743CP).
2. 500mah lithium-ion cell (I used from old rc chopper).
3. 1.2 inch 2 watt speaker (buy here https://www.amazon.in/dp/B071VPVGZJ?ref=ppx_pop_mob_ap_share).
4. Small plastic container (recycle).
5. Screws for support (local store).
6. Holding loop.

Making the Enclosure

So for making the enclosure I'm recycling a small plastic container. As shown in the above images the containers colour is white so I don't need any spray paint or vinyl wrap to decorate it. U can use something to paint it but I like the white colour so here I'm not going to paint it. I cut a hole on the bottom of the container to fit the speaker and I cut the top completely to fit the circuit. The size of the circuit is just same as the diameter of the container so here the circuit will work as the base of the speaker.

Adding Electronics

So once we complete making our enclosure, it's time for some electronics. So for the bluetooth and amplifier module I am using the circuit from a cheap bluetooth speaker as I've already mentioned. For power I'm using a 500mah lithium-ion cell salvaged from an old rc chopper. For the speaker I'm using a 1.2 inch 2 watt speaker I bought from amazon for $1. We don't need any diagram as it's written in the circuit board where to connect the battery and the speaker. So I simply soldered them in place and the module started working as normal. I desolder the switch and aux, usb and the card holder from the module to fit inside the box. After that I cut some holes to place the micro USB port and then popped the speaker over it.

Gluing Everything in the Enclosure

I glued the speaker on top with fevikwik and then placed the module on bottom and fit it in place with hotglue. I also covered open places with hot glue to seal it. Make sure to place the micro USB in proper way to charge it.
