The CES was the official launch of the Clark Synthesis Tactile Sound Transducer, more informally known as the Buttkicker Shaker. The function of the device is to allow people to feel the virtual reality of movies. Located on the floor beneath a person’s seat, the device hooks up to a television or home theater and works by transforming the sound of, say, an explosion, into vibrations.

According to Curtis Clark, president, Clark Synthesis, the product consists of a plastic disc or dome. A voice transducer is located on one side of the dome and a magnetic structure on the other. An input signal acts to deflect the disc against itself, creating the vibrations felt by the user.

The dome is made out of an ABS/PBT blend. The material was chosen because of its frequency response.

“We used to make the dome out of polycarbonate and it gave more response to higher frequencies,” says Clark. “With this product, people like the lower frequency response you get with the ABS/PBT blend.”
