Brief
Designed and handmade this speaker project for BANG & OLUFEN to understand how the speaker works and how to arrange electronics components.
Term Project
Duration: 14 weeks
Tool: Craft Making, Branding
Year: 2022
It is a high-end brand from Danish, making audio products, television sets, and telephones
Use metal and wood to make speakers and always use silver, black and gold colors. It looks warmer and is suitable to put at home.
The Overall shape is round and Clean. Due to the cost of production, the premium materials used to manufacture its speakers, and the audio quality, the speakers are quite expensive.
Ideation Sketches
Mockup 1&2
At first I was just studying how to make the shape of the speaker good, but I couldn't find a good way to hollow out the inside.
Mockup 3&4&5
Then I put handle at the side and try to mill the whole thing by hand
After added on the front piece
I tried to hand sand the inside
Mockup 6&7
Use Mockup 5 to vaccum form this
Starting with the seventh model, I cut the model in half at the beginning and then used the mill to hollow out the inside, but because of the size of the problem is not very good mastery, so the drill through
Mockup 8
The first time to complete a better model is to first cut the appearance of the model, then cut the back half into two halves, and measure the distance to the two piece mill hollow. Then the two pieces are bonded together with bondle.Then make a template to connect the front panel together. But the internal because there is not a good measure of size, the internal mill is very uneven
Mockup 9
The second time to complete a better model. But I still didn't measure the data very well, resulting in the side walls being penetrated. And when making the front piece, the middle part was cut away during the router because the passive driver was too close.
Mockup 10&11
The third time to complete a better model. Because the back piece is cut into two halves only after cutting the whole main form, resulting in the whole is not very even and looks asymmetrical
The fourth time to complete a better model. Because the measurement is incorrect, the PCB board cannot be put inside. But I changed the way to cut the back piece so it looks more symmetrical.
Final Model Making
Prepare the templates
Cut a whole form into three parts first, then bond the three parts and cut the whole main form through the drawing. Next, hollow out the back piece with a mill machine and glue the two halves together with epoxy. Use the template to cut the button and the left and right sides as needed. Use the cutting face template to locate the screws
Add two layers primer and send it into very smooth surfaces without any small holes and prepare to spray the paint
For the final painting part, I used Tamiya Mica Metallic paint to give the speaker a more luxurious look. Then, I sprayed it with clear paint to make it even shinier.
After I cut the foam part and sprayed it, I put the driver in it and started to make the front masking part. I first cut a 1/4in acrylic plate and prepared the black denim. After spraying the spray glue on the acrylic board, put the acrylic board on the flat denim. Then use scissors to cut along the edge of the acrylic board, and use super glue a little bit to fold the excess fabric inward and stick it to the back of the acrylic board. Put the acrylic board with the glued fabric on the front foam piece is the last step
Assembly
Tighten each part with screws, install the buttons, and stick the logo and other details label
· All components can be perfectly fixed inside the sound
· Every button works properly
· The shape of the stereo and the masking of the front panel make the music reverberation excellent
