University Project

[Vettel]

Hi,



I am currently designing a iphone/ipod sound system for my final year project at university.

I have little to no audio knowledge so was wondering if I could get some advice on a few aspects of my project.

The idea behind my system is that it is to create a user experience were no matter what angle the user is to the system they will have the same experience from interacting with the interface to hearing the music. The system also includes a unique feature of sharing music between friend's iphones/ipods. The system would ideally be used on a coffee table or at a breakfast bar for example, where users will all be facing a different direction to it.

The system unit size is expected to be 330mm in diameter and 100mm in height (approx.)



Please excuse my audio knowledge naivety!

My original thoughts were to have a downward firing 6" sub with a bass reflex and five 1" speakers orbiting the sub in the same unit. Basically just using the same configuration as found in the harmon/kardon soundsticks but laid out in a different way. (http://www.harmankardon.com/EN-US/Pr...SOUNDSTICKS3AM)

Is this sensible and what do i need to take into account?

How hard or important is it to calculate the enclosure volume and port size for the sub? only needs to an approximation.

Any thoughts on the audio side would be greatly appreciated, open to any other audio design solutions too!

Thanks

How about a upward firing driver and a conical reflector?

I had been looking at an inverted cone with an upward firing driver, but due to styling issues and the low profile of the unit, i am not sure it would work well.

If i were to go with the 5 satelite speakers orbiting the woofer. would i need to put the satelite speakers in a seperate enclosure within the main enclosure?

Is this option suitable?

thanks for the help

Yes, you will need to protect the small drivers from the pressure inside the sub.
