Product Evaluation:

 My overall thoughts on this product are very good, I am pleased with the outcome and am very happy with the sound quality and output. I did however want to make the unit more powerful by adding a 40W amplifier and and electro lumenesent wire to emphasize the 'Tron' brand identity a little more,
this would have dramatically halved the power supply life and, like the addition of the Electro Lumenesent wire would have meant an addition of an external power supply.
Although my finished unit is large, I don't feel this will effect it to much as a practical amplifier and speaker system as the use of a shielded speaker means it can be placed anywhere without interference and the sound quality more than compensates for it's size - and it still only requires 1x pp3 battery.

Brief.

Assignment:

‘MP3 players are very popular and are ideally suited for individual listening. Sometimes however it is useful to amplify sound

so that the device can be listened to without the restriction of headphones or a small group of people can listen to it

together.’

The above is a typical context taken from a GCSE Short Course specification.

Your task is to design and manufacture a prototype product in response to this context that incorporates the

given amplifier circuit. CAD/CAM is to be used extensively in the development of your prototype. This will be

a corporate 'freebie' used to promote the launch of one of the following new ventures:

•  an energy sports drink
•  a product to be used on the set of the movie TRON Legacy.
•  a high speed commuter rail network
•  a web based information service for the
• 2012 Olympics

Pro/ENGINEER and Corel Draw should be used to refine and develop the product’s shape, form and

function. The prototype product should be manufactured using CAM equipment (eg. laser cutter, Fused

Deposition Modeller, CNC router, sublimation printer etc') as the principal means of production.
