material vibration modes (also called cone breakup) are the major reason for reproduction errors in diaphragm based loudspeaker transducers. material vibration modes are chaotic phenomena. the modes are not gradual phenomena.
they manifest as a sudden and drastic change in material behavior.
they are hard to predict. they are
impossible to model or simulate with presently available modeling
programs.
There is a solution to the problem of material vibration modes in loudspeaker diaphragms. i use a proprietary vibratory analysis technology
to map the material vibration modes of loudspeaker diaphragms under
dynamic conditions. this new technology allows me to determine
the origin or starting point of every material vibration mode on a
transducer's diaphragm and to provide clients with a map of the critical areas on any cone type diaphragm or dust cap.
using that map, cone breakup can be controlled. i can provide clients with corrective designs utilizing the most efficient and effective method and technique for controlling cone breakup (patent pending). the effectiveness of my vibratory analysis technology and vibration mode control techniques have met the most stringent standard of science: independent verification.
the revolution in sound reproduction
has begun. you will see whisper cone designs appearing
in more and more loudspeakers. for more information please examine the supporting documents provided on the documents page of this web site. if interested in more information on how controlling material vibration modes can improve performance in your cones, dust caps, assembled transducers or loudspeakers, please contact me.
