Beryllium PVD dynamic driver in an ultra high density ceramic enclosure.

SKULyra Category

Integrating a custom 8.5mm beryllium PVD transducer into a tuned high mass ceramic enclosure is a powerful combination.  The Lyra delivers a natural and dynamic sound–exceptional high-frequency extension, silky smooth mids, and deep, powerful bass response. A sound, free from grain and harshness.

Neodymium rare earth magnets, the strongest type of permanent magnet commercially available are utilized in the Lyra’s dynamic driver.  This powerful and compact magnet  ( 3.8mm x 1.2mm x 1.3mm) provides the magnetic field for the voice coil’s operation.

The Lyra’s enclosure material is an ultra high-density ceramic, Zirconium Oxide Ceramic (ZrO2).  Used as an acoustic chamber, the physical properties of this ceramic carry excellent detail.  Less distortion extended high frequency and a natural tonality.  It minimizes vibrations that could distort the driver’s sound if left unchecked.  It is a complex multi-stage process to produce each earphone enclosure.  The sintering process alone is 1400 degrees C for 72 hours in which the parts harden and shrink.  The mixing of the ceramic material, granulation, injection molding and debinding all are required before the sintering process can begin.  Afterward, each component is polished, assembled and examined for quality assurance of the final enclosure.
