Product Overview

The Comprehensive Audio Test System integrates an audio interface, power amplifier, and signal conditioning module into a single platform, providing a complete solution for electroacoustic testing.

Equipped with 4 input channels and 4 output channels, the system supports simultaneous audio signal generation and acquisition. It features low noise, ultra-low distortion, and excellent frequency stability. When combined with host computer test software and acoustic measurement algorithms, it enables fast and accurate measurement of key acoustic parameters for a wide range of electroacoustic products.

The system is suitable for both laboratory R&D and automated mass-production testing.

Specifications

Application Scenarios

- Acoustic performance testing of TWS earbuds, headphones, and wired earphones

- Acoustic parameter testing of smart speakers, loudspeakers, receivers, and microphones

- Acoustic testing of mobile phones, intercom systems, and automotive voice terminals

- Algorithm verification for noise-cancelling microphones and speech recognition devices

- Performance evaluation and R&D testing of electroacoustic devices

- In-line acoustic testing for automated consumer electronics production lines

Recommended System Configuration

The instrument can be used together with soundproof test enclosures, artificial mouths, self-developed test speakers, standard measurement microphones, and other acoustic accessories to form a complete acoustic testing system.

Typical Test Process

Audio Test System outputs a test signal → Sound source generates the acoustic signal → DUT receives or reproduces the signal → Audio Test System acquires the DUT output signal → Host computer software automatically analyzes and calculates the required acoustic parameters.

Customization

Expansion Explanation

The standard 4-input, 4-output configuration meets most conventional electroacoustic testing requirements.

For applications requiring additional channels, higher output power, special interfaces, or other customized hardware configurations, tailored solutions are available based on specific test requirements.
