Introduction: Portable Bluetooth Speaker

Hello fellow speaker builders! This is not my first speaker build, it began when i was young, my first few speakers were not that great and full of neon lights. With each build the quality improved and the speakers began to look more stylish. I build this speaker when i was 19, it was a very hard and complex build but I have learned a lot. Unfortunately I have not documented the entire build. I am from Holland, so there can be some misspellings in my English.

Components i used:

- TA2020 12-15V amp

- Tangent speakers

- Battery 12V 7.2Ah

- Marmitek Boomboom 75 Bluetooth Audio receiver

- Usb Charger(to charge my iPhone)

- Crossover

- Speaker front cover(not in the pictures)

Step 1: Frame and Bending Wood

The first step was creating a frame as shown on the image. Then I bended wood around the frame, 2 pieces of (i think it was) 0,5 mm that i soaked in water for a few hours, I never bended wood before so this was a very hard and annoying job.

Step 2: Components and Wiring

Then I placed all the components into the speaker. I also fitted the Bluetooth receiver in the top of the frame, which was also very hard because I had to place the circuitboard with the button and still maintain the shape of the speaker which resulted in filling the gaps with filler or putty. Then I drilled all the holes in the mounting dish for all the connectors on the backside and then I wired everything.

Step 3: Sanding Down and Painting

The final step was sanding the speaker so i could paint it. This was a very time consuming job, I'm a bit of a perfectionist so I wanted it to be perfect. Then I painted the whole thing, first with primer and then with white paint. I have never painted before so this was also new to me. It took me seven coats for the result that I wanted, between each coat dry and wet sanding. I'm happy with the result, I'll hope you like it to!

    Nice build with an interesting design, where all too many just go for a plain square box. I am missing a few pictures of the build as it is coming along...
    Here are a few pics of the designs I am currently working on.

    Thx, unfortunately I didn't take a lot of pictures during this build. My next build is gonna be more documented. Awesome looking design you've got there, my next build is also gonna be a cylindrical shape.

    The tapered and curved shape I think is good for a speaker. Minimum parallel surfaces in the interior space mean the enclosure would not suffer much from standing wave reflections which can be a problem with rectilinear box designs.

    I love the shape, it's very unique and modern! On the flip side I imagine it might be a bit wobbly when playing low frequency sounds. Did you notice anything like that?

    Thx! You are right, the first time I played this speaker the low frequency were not that great. At first I stuffed the speaker with only wool, this resulted in echo(reverb, reverberation) in the case. Then I put damping material into the case(see picture) which makes the speaker sounds great. The sound of the speaker is at his best when placed a few inches from a wall.
