“Buzz Buttonz” is a tradmarked name for padded disks, placed adjacent to the human body, which convert sound into tactile vibration. The disks are designed to oscillate within specific frequency ranges in order to resonate with different body structures. For example, the chest responds best to frequencies around 500Hz; the spine responds best to frequencies around 80 Hz (or even lower, below auditory range). The “buttons” (4 and 6 inch in diameter) are powered by a 12v amplifier receiving a Bluetooth signal.
A couple patents are now pending, and I have a limited number or prototypes that are being test-marketed. If you are interested in obtaining a prototype, contact me by email at firstname.lastname@example.org. Put “Buzz Buttonz” in the heading.
