I am quite happy with the finished speaker however there were some stumbling blocks along the way with regards machining the back of the speakers as aforementioned in the blog. Overall this exercise was very informative as I have grown a much better understanding of how to draw on Creo and CorelDraw as a means to generating a physical outcome.
Creo in particular was very useful as it enabled me to assemble parts to investigate if all drawings would complement each other in terms of size and fixtures. It also provided a realistic interpretation of how the finished product would look through the rendering tool which also allows a the product to be placed in a scene.Cad/CAM is a useful method of manufacturing parts as it produces the required parts accurately and in a shorter period of time than one would accomplish by doing it by hand.
I believe this speaker achieved the theme of having a contemporary feel by subtly incorporating a modern twist on a retro design. Overall the speaker was relatively cheap to manufacture in comparison to its potential retail price. The approximate price breakdown is as follows:
Oak: £12.00
Jelatong: £5.00
0.5mm Acrylic: £2.00
3mm Acrylic: £1.80
12v 1000mA Power supply: £14.99
On/Off Switch: £2.00
Rapid prototype of switch holder: £5.00
Briwax: £9.00
Total: £51.79
Even though I would not like to count the man hours put into the design and manufacture of this project I thoroughly enjoyed it as I was able to incorporate almost all manufacturing methods available in the workshop. The equipment used are as follows:
Flatbed router
CNC
Rapid prototyping
Lazer Cutter
Wood turning lathe
Band Saw
Milling Machine
Pillar Drill
Vacuum Former
Chisels
Bar Clamps
Wood Files
Spray Booth
Sand paper
The design of the top speaker shell allows it to be turned through a distance of 360 degrees from the base which allows users to maximise the sound no matter which part of the room the are in.
