Default Distributed Mode Loudspeaker vs Vibration Panel Technology

Default Distributed Mode Loudspeaker vs Vibration Panel Technology. Is there a difference?

I'm doing my best to educate myself on distributed mode loudspeakers, with the goal of building hidden, hifi quality speakers in my house, either in the form of the wall itself, or as artwork panels suspended from the ceiling or mounted on the wall.

I'm new to DIY, so forgive me for my naivitae. I originally came across DML with Tech Ingredients review of DML panel options in this informative Youtube video.

It seems these speaker work best when the panel is suspended in air and not affixed to anything. There are also expensive "invisible speakers" out there sold that are built into the drywall and use the wall as the loudspeaker. These are sometimes called "Vibration Panel Technology," I believe is the same thing, but I am not sure.

What I am unclear about is how these speaker perform well when connected to the entire wall and not suspended?

If you know of projects in which people have built DML or other speakers that either use the wall as the speaker or can be affixed to the wall or suspended like artwork, I would appreciate seeing those projects.

I think you mean 'vibration speaker technology's, but yes they are referencing the same thing -- a panel of some kind being driven by an attached 'exciter'.
