Mobile Phone Testing

The FLEXUS FX100 is a state-of-the-art audio test system that meets all the requirements of today's high-volume mobile phone production. The FX100 provides a detailed view of the voice quality and thus the constancy of the mobile phones manufactured.

The total test time for a comprehensive test with the FLEXUS Audio Analyzer is typically below one second. FX100 supports all standard audio-acoustic measurement functions and the sophisticated rub & buzz detection of mobile phone transducers.

Components / Subassembly Test

Testing the quality of the transducers, microphones or subassemblies is important to reduce the failure rate at the final test. Sorting out defective modules at this early stage is much more efficient than rejecting the costly completed phones at the end of the production line.

The audio quality test typically comprises following measurements:
  • Frequency response
  • Impedance response
  • Sound pressure level (SPL)
  • Microphone sensitivity
  • Rub & Buzz of transducers

Final Acoustic Testing

The FX100 Audio Analyzer is ideally suited for the acoustic testing of transducers and microphones of mobile phones. The optional Rub and Buzz detection ensures a 100% correlation to the human ear, so making tests by human operators obsolete. It is the first solution that enables the manufacturers to conduct a reliable automated quality test. The system includes phantom power supply for the measuring microphone. The typical test cycle time is < 1 second incl. a patented noise cancellation algorithm that immunizes the measurement process against factory noise.

The audio quality test typically comprises of the following measurements.
  • Frequency response
  • Sound pressure level (SPL)
  • Microphone sensitivity
  • Rub & Buzz of transducers
