Default Amplifier casing design

Hi everyone,

For my study Industrial Design Engineering I am doing my bachelor assignment at a company that develops several electronical parts for amplifiers. They sell these electronics to different companies that actually develops amplifiers. To show potential clients the quality of these components they have also made a demo-amplifier. At this moment it is just a PCB with plugs for the input and output. Now it is my job to design a casing so it looks like an actual amplifier.

At this moment I have made several concepts which all have interesting looks. Now I have to select a final concept that I will further develop. To select the final concept I ask input from the company. But it is also interesting to know what the end-user (you) will think, because if the amplifier would be in the stores the end-user has to buy it. So I attached my 4 concepts and I would like to hear your opinion. Which amplifier is your favorite (and why?). Note that these concepts are only the basic shape with some details. I did not focus on the user interface yet since that is a design on its own.

I hope you could give me some good input, also feel free to give suggestions, this can always give new insights.

Thank you in advance!

Hi, I don't understand the above, can you clarify?

Hi Scottjoplin,

Well as you can see in the attachement of my post (I hope that the photo is visible, because i'm not sure if it uploaded correctly) you can see that the 4 models don't have so many knobs and it is not clear how to for example turn the amplifier on or off or select a different channel. Everything that has to do something with the interaction with the user of the product is called the user interface (the knobs, the screen, etc.)

But every concept that I have drawn can have a wide variety of user interfaces (for example: put the volume button, to the right instead on the left, use a touch screen instead of a physical knob) So I don't want to distract people when looking at the drawing. I only want to specify now on the overall shape of the amplifier. Once I have chosen a final concept I will focus on the user interface; what knobs will I use, where will I put them etc.

Did I answer your question?

I like #2 and #4
This is due to their form factor (width vs height) and so looks nice

However most of what design work will depend on the functional demands placed on the casing eg heatsinking

Yes, that's what I was thinking, how the other controls will affect the overall appearance

Number one based purely on looks for me. +1 on the ventilation and cooling requirements being considered at this stage.

Number 1.

I'd like that more if the display portion was thick - recessed as per the drawing but extending out flush with the front of the case.

Bonus points for getting the display in the central depth to give it a 'floating' look.

Yes you're right the overall controls will indeed change the appearance and it might be difficult to give a opinion that is not biased on the controls. However it can be very time consuming to make multiple interfaces for every concept. So first I want to find the overall shape, I hope the (lack of) controls that are on the concepts now are not to distracting?

I believe in 'form follows function'
Work out the user interface you need, then the shape will follow as the best way to implement that user interface, and the other requirements like heat dissipation.
I have a Harmon Kardon amplifier that was "styled" first then the user interface had to fit the supposedly "stylish" front.
It's terrible to use, for instance inconvenient to read the tiny print on controls - apparently easy to read labels weren't "stylish", and other similar poor user interface problems.
I selected it based on the electronics but the usability is so poor I consider it one of the worst products I have owned.
Please don't make more products like this, there's already too many.
Read Victor Papanek!

Best wishes
David
