Headphone Acoustic Testing Solution
The headphone electroacoustic testing system is a highly accurate, flexible, and scalable integrated electroacoustic testing platform. The core service covers the entire process of headphone research and development, targeting core requirements such as circuit debugging, acoustic structure optimization, and performance boundary verification during the research and development stage, to achieve precise quantification of audio and acoustic performance indicators, problem localization, and parameter iteration. Different from the "compliance judgment" of the mass production quality inspection system, it focuses more on "deep analysis, flexible debugging, and multi scenario verification", and is the core R&D support equipment for headphones from scheme design to mass production implementation.
A2B Car Microphone Testing Solution
The car microphone is the core component for car voice interaction (navigation, voice control, communication), active noise cancellation (ANC), and in car sound field acquisition. Its audio performance directly determines the speech recognition rate, noise resistance, and communication clarity. By using the high-performance audio analyzer independently developed by Aptec, combined with acoustic testing accessories such as electroacoustic testing interface, artificial mouth, standard microphone, and sound calibrator, the acoustic characteristics of the microphone can be tested.
A2B Automotive Power Amplifier Audio Testing Solution
With the development of car audio towards multi-channel, intelligent, and digital directions, coupled with the complex environment inside the car and the popularization of new bus technology, car amplifier audio testing is facing new challenges in channel synchronization, bus adaptation, distortion control, and other aspects. ·Multi channel and synchronous testing: The power amplifier has up to 32 output channels, which places extremely high demands on the number of acquisition channels and synchronization of the testing equipment. ·Digital bus testing adaptation: With the widespread popularity of car audio buses such as A2B, new demands have been put forward for interface adaptation of testing equipment. ·Nonlinear distortion: Currently, mainstream D-class amplifiers are susceptible to nonlinear distortion caused by inductive components, requiring precise measurement of THD+N at different powers and frequencies, which further demands the performance of testing equipment.
A2B In-Vehicle Audio Test Solution
The ABTEC Ax audio analyzer, with its high cost performance, outstanding system performance, and extensive expansion capabilities, comprehensively covers all audio testing scenarios, making it the preferred testing equipment for both consumer and professional audio products. For automotive infotainment testing, the audio analyzer can complete core audio performance tests when paired with filters; by integrating with FM/AM signal generators and other signal sources, it enables full-scenario testing.
