Micro-Speaker Multipoint Tool (MMT)

  • Advanced miro-speaker modeling
  • Coping with irregular Vibration modes
  • Automatic post-processing
  • Complete Parameter set
  • Separation of enclosure and air load
  • Pure mechanical parameters
MMT

The MMT module performs the post-processing of the results of multiple LPM measurements performed on micro-speakers to increase the accuracy of the parameter identification. Spatial averaging of the voice coil displacement measured at multiple points on the diaphragm compensates for rocking modes and other irregular vibration. Additional measurements performed in vacuum and in the final enclosure show pure mechanical parameters of the transducer separated from the acoustical elements. An advanced creep model (Ritter) is supported, which models the significant visco-elastic behavior of micro-speakers. 

Requirements

- Distortion Analyzer 2 hardware

- dB-Lab Software

- LPM Module

- Power amplifier

- Laser

- PC

It is recommended to use coating spray for micro-speakers and tweeters with transparent and shiny diaphragms.
