Abstract: The exemplary embodiments herein provide an assembly for transmitting vibrations to a helmet worn by a user, including an annular element adapted to adhere to an outer surface of the helmet. The exemplary embodiments also include an assembly which rotationally connects with the annular element and comprises a bottom housing having a floor, teeth near the floor which engage with the annular element, and a sidewall extending upwardly around the circumference of the circular base unit. The embodiments further include a top housing having an outer sidewall that fits outside of the sidewall of the bottom housing and a plurality of apertures in a top surface; a pressure transducer placed atop the floor; and a mechanical user interface placed above the PCB and having at least one button which extends upwardly and through one of the apertures on the top surface of the top housing.

Abstract: The exemplary embodiments herein provide a device for conversation between users during activity comprising a pair of arms which are substantially symmetrical about a central axis. Each arm preferably has a first portion which rests behind the head and below the occipital bone of the skull of a user, a second portion extending forwardly from the first portion and towards the ear of a user, a third portion which extends upwardly and away from the second portion, wrapping over the top of the ear of a user and also extending inwardly towards the central axis of the device, and a fourth portion which extends downwardly from the third portion and increases in cross-section area as it approaches a bottom cavity which contains a vibration exciter.
