*raises hand*
Audio engineer here- This design would present zero challenges to picking up enough audio signal. There is plenty of exposed grill mesh to plant a transducer behind, and for its perceived intended purpose (voice mainly, at a reasonable proximity) would certainly fulfill its duties as a transducer housing.
Even more importantly in the success of actually bringing this design to market is not the audio performance that might be achieved with the design, but it is more about the visual allure of the object. Packaging sells, regardless of performance and specs.
I love the design of old generation microphones, the mechanics of how they were put together, the purpose of each component. The look was derived from its use, and the outward appearance was driven mostly by the requirements of achieving the best audio capture. Nowadays with transducer tech that can achieve great performance in small packages, a designer can house the guts in pretty much any package they want to and get acceptable performance for 90% of the users.
So, with this design, I think it would have a real opportunity at production simply from the fact that it looks good. The packaging could be made to look good. Audio performance could be made to accomodate a podcaster, webcaster, casual tutorial creator. Add a 1/4 20 screw mount underneath and you have a nice looking vocal mic that can be mounted on a stand. If you wanted to go old school, create a shock mount for studio or live use. The design is versatile and could be adapted in many ways. I do really think this has potential, more so than a lot of devices out there.
Nicely done, sir.
