Notebook audio test
The laptop has experienced the process from being bulky, black and white, and color screen to reduced volume, lighter weight, and increased functional memory. As the laptop has more and more applications, better sound quality of the laptop and Mic call effects are also required. The latest generation of laptops has gradually added a series of features, such as call noise reduction stereo surround sound. In order to meet the new requirements for audio testing of laptops, CRY Sound's latest laptop test solutions include highly automated test fixtures and cabinets, which can easily, quickly and stably test the audio characteristics of laptops.

Highly automated testing
Speaker test
CRY6151B connects to a laptop and makes it sound via WiFi → microphone collects the signal → the signal is input into the CRY6151B for analysis via the MIC interface
Microphone test
CRY6151B outputs signal, makes the mouth simulator sound via the MOUTH interface → the laptop MIC acquires signals → the signals are connected to CRY6151B for analysis by the laptop via WiFi
Fan noise test
CRYSOUND establishes a connection with a laptop through a network cable, and controls the laptop cooling fan to run in the fast or slow mode → the microphone collects fan noise signals → input signals to CRY6151B through the MIC interface for analysis
Laptop headset audio port test
CRY6151B is connected to the laptop through a network cable. The laptop is controlled to enable the audio interface to output signals, which are directly inputted into CRY6151B for analysis through the LIN IN L/R interface through the headset audio cable
