Micro Suspension Part Measurements

This Spotlight reference article details a simple and fast procedure for testing the diaphragm used in microspeakers, headphones, tweeters, and microphones. Meaningful information comparable to Stiffness KMS and Mechanical Resistance RMS of the Thiele-Small (T-S) parameters is the basis for tuning the production process and for communication between transducer manufacturers and soft parts suppliers. This article was originally published in Voice Coil, January 2016.

Measurement and Perception of Irregular Loudspeaker Defects

June 8, 2015 by Wolfgang Klippel and Robert Werner

Measurement and Perception of Irregular Loudspeaker Defects

Loudspeaker defects caused by manufacturing, aging, overload, or climate impact generate a special kind of irregular distortion commonly known as rub & buzz, which is highly audible and intolerable for the human ear. This article, originally published in Voice Coil, June 2011, discusses how to measure and detect those defects.
