Thinkgeek’s $150 Bluetooth Communicators are based on 3D scans of a prop communicator; pair it with your phone and clip it to your belt: when you get a ring, the psychedelic hypno-disc in the middle will spin prettily, flick it open and start talking.
It’s also a cosplay prop, with 20 sfx from the show that it can produce on demand. Works great as a streaming audio speaker, too, with a 36mm speaker.
