Vacuum Measurement Kit

  • Get precise mechanical parameters
  • Separate mechanical system from acoustical system
  • Investigate impact of radiation impedance and air load
  • Scanning of mechanical vibration
  • Remove acoustical damping

Electro-acoustical transducers, such as loudspeaker drivers, micro-speakers, headphones and microphones, are measured in a vacuum to identify properties and the parameters of the electro-mechanical system directly while the effect of air is eliminated. The Vacuum Measurement Kit meets the special requirements in the loudspeaker application, such as a flat vessel to accommodate loudspeaker drive units of large diameter, air sealed terminals to feed the electrical stimulus and a planar glass plate for laser scanning.
