Some manufacturers use speakers and others use devices that vibrate but make no noise. I was wondering if anyone could help me with this. I am looking for the devices that make no noise but create vibrations. I am told that the vibrations go through a liquid crystal type medium which the cushion is filled with. Any help would be appreciated. Thank You David ------- End of Forwarded Message
