Found an Audio Sonic 'Moving Studio' body warmer with two speakers. It sounds like a pair of bad headphones but it has the cool factor (or the nerd factor??) . Can't find any info on the web. Maybe it was a local (Dutch) product, especially made for some kind of event? More detailed pictures: check the thumbnails.
Those speakers remind me of the ones in the Parcel boombox bags https://www.google.com/search?q=par...WrSxUIHYpwC-wQ_AUoAnoECAsQBA&biw=1680&bih=907
Nice! I saw a guy on Shark Tank who made jackets, somehow he patented the inner holes for headphones and USB cords in jackets, supposedly over here nobody can put in those holes.
They remind me of the very rubbish ones I screwed to the parcel shelf of my Morris Marina Coupe, yes it was baby poo beige (was there another colour?)
A similar product was launched in Greece when I was a teen (looong time ago, early 80s) ! Good find !!
For anyone who doesn't know what a Morris Marina Coupe in baby poo beige looks like My Father actually bought two four door Marinas new. The first was in Navy Blue but was obviously well camouflaged as two different people drove into it. The second was a dark red and had luxury features including velour seats and a radio. Fast forward to the 1980s Ford Capri (a European cope inspired by the Ford Mustang) was in "Tuscan Beige" which was close to the collour of most corrugated cardboard. Definitely not my first choice in colour but it was a good price. I had a much larger better vertsion of those speakers in the doors. The previous owner had cut a large (possibly 6") hole in the passenger door panel only to find there obviously wasn't enough clearance to fit the speaker he wanted and still wind down the window. After much research I found that Panasonic made a very shallow speaker of the same diameter so I bought a pair of those and finished the job connecting them to a nice Pioneer car radio cassette. Most youngsters will never experience the "fun" of fitting your own car stereo.
Sorry to get a little off topic but that Morris looks like a crappy copy of the Chevrolet Vega. The Vega's suffered from the same tin worm the English had and it's extremely rare to see one today. In hindsight the Vega isn't as bad looking as most of the crappy two door hatches from the 70's. I think USA Cars had a little extra space everywhere so you could fit speakers front and rear pretty easily.
...or 1967-1972 Opel Kadett B... one like that in „grannie‘s underpant-blue“ was my first car back in 1985
Blame me for the scope creep There were a few uses of "active surface" speaker technology around that time, I recall there was talk of wearable versions, did any of it happen?
I was thinking that the Chevrolet Vega looked like the first Opel Manta https://en.wikipedia.org/wiki/Opel_Manta#/media/File:Opel_Manta_Garmisch.jpg Not that surprising as they were both GM products. I'm thinking that your Kadett did well to last that long. My first car was a pea green MK1 Ford Escort that was rusting away at 8 years old. With the Capri I posted a picture of, I used to respray the sills every year. Even then, at 11 years old, when the picture was taken, it had had to have the front suspension mounts plated and welded.
