A Chair as a speaker : Rumble Seat
The main enclosure houses a powerful subwoofer, two mid-range speakers and four tweeters. Several Rumble Seats can be linked together to allow a group of people to enjoy each other's music and create unity through sound.

I know that a student of Keio University created a chair for conversation while ago. It tranforms human conversation into pulse in real-time, and it makes chair swing. We are able to feel other person's impassiveness or tension.It might be interesting if it can let us know throb each other.
