Mobile Phone Testing
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
