Smartphone/tablet PC audio test
Smartphones and tablet PC are integrated with entertainment, office and other uses. Such equipment contains a variety of acoustic devices, such as speaker, receiver, noise-reduction MIC and call MIC. The performance of acoustic devices will significantly affect the user experience. Thus, the audio testing of smartphones and tablet PC becomes extremely important. How to quickly and efficiently test so many acoustic devices in a smartphone has become a major challenge for mobile phone manufacturers.

Speaker testing
The smartphone communicates with the host computer through the USB interface to produce sounds → the microphone collects the signals → signals are input via the MIC into CRY6151B analyzer for analysis.
Smartphone transmitter testing
CRY6151B uses the MOUTH interface to output signals and make the mouth simulator sound → the smartphone MIC collects sounds → USB interface connects to the host to obtain data for analysis.
Smartphone receiver testing
A piece of pure tone is played on the mobile phone's call end to make the phone receiver sound → the high-leak artificial auricle and receiving sound signals → signals are transmitted to CRY6151B via the MIC interface for analysis.
