Possibly some form of high frequency loud speaker (tweeter), but I am not saying that with any confidence. What do you think it is? Where is it?

Looks like an annunciator or horn etc.

Google says it's a "jogger".

Surface transducer.

It's a reverse loudspeaker.

The voice coil is attached to a weight while the relatively light magnet is mounted to a panel. The recoil from moving the weight shakes the panel to which it is bolted, and the panel radiates the sound - or vibration.

"jogger" is a fair description.

Never heard of such a thing! I imagine they sound crap!

I never said they sounded good. :grinning:

OK, so I had some difficulty remembering the device that this discussion brought to mind. After a couple of sleeps, it came to me.

It was the "Aura Interactor". Possibly worth more now as a legacy item!

Wikipedia cites:

uses Aura's patented electromagnetic actuator technology to convert bass sound waves into vibrations

which of course, simply refers to one of the transducers under discussion here.

And I'm pretty sure I have (at least) one - somewhere. :sunglasses:
