1. A collar unit device comprising:

  • a receiving cavity;

    a metal electrode probe, wherein at least one elastomeric ring encircles the metal electrode probe, wherein the metal electrode probe comprises a first end and a second end;

    the receiving cavity for receiving the metal electrode probe, the receiving the metal electrode probe comprising securing the metal electrode probe to the collar unit device, wherein the at least one elastomeric ring mechanically isolates the metal electrode probe from the receiving cavity;

    the metal electrode probe for detecting vibrations of one or more acoustic events and transferring the vibrations of the one or more acoustic events to a piezoelectric element;

    a grommet component for positioning the piezoelectric element, the positioning including receiving the piezoelectric element in a securing feature of the grommet component, the positioning including an upper portion of the grommet component contacting a surface of a printed circuit board assembly, the positioning including a lower portion of the grommet component mating with a housing feature on an interior surface of the collar unit device, wherein the upper portion contacting the printed circuit board assembly and the lower portion mating with the housing feature comprises locating the grommet component in a secured position;

    the grommet component in the secured position providing a force on the piezoelectric element to maintain contact between the piezoelectric element and the first end of the metal electrode probe;

    the piezoelectric element for receiving the vibrations of the one or more acoustic events, the receiving the vibrations including generating an electrical signal proportional to the frequency and magnitude of the vibrations;

    at least one processor located on the printed circuit board assembly for receiving and processing the electrical signal.
