Semi-Automatic Speaker Testing Solution

Product Details
Inquiry

Bluetooth terminal is a test system independently designed and developed by Aopuxin for testing Bluetooth terminals. It can accurately test the acoustic abnormal sound of the speaker unit. It also supports the use of open-loop test methods, using USB/ADB or other protocols to directly retrieve the internal recording files of the product for voice testing.It is an efficient and accurate test tool suitable for sound testing of various Bluetooth terminal products. By using the abnormal sound analysis algorithm independently developed by Aopuxin, the system completely replaces the traditional manual listening method, improves the test efficiency and accuracy, and provides a strong guarantee for the improvement of product quality.

SIN PERFORMANCE

Improve test efficiency

Compared with traditional manual testing,semi-automated testing can significantly improve the speed and efficiency of testing.

Flexibility and scalability

Allows developers to quickly adjust testing strategies as testing requirements change,while also facilitating the introduction of new testing features and technologies.

Improve accuracy

Using Opxin’s self-developed abnormal sound analysis algorithm, accurate testing of speaker units can be achieved. Accurately identify abnormal components in the sound,and at the same time, use the open-loop test method to further enhance the accuracy ofthe test.

Strong applicability

It is suitable for the sound test of various Bluetooth terminal products, whether it is headphones, speakers or other Bluetooth audio devices, you can get accurate test

TYPICAL TEST INDICATORS

Typical test index

Frequency response	It is an important parameter of power amplifier to reflect the processing ability of different frequency signals
Distortion curve	Total harmonic distortion, abbreviated as THD. The curve results are obtained by analyzing the higher harmonic distortion of the signal.
Abnormal sound factor	Abnormal sound refers to the squeaking or buzzing sound of the product during the working process, which can be judged by this indicator.
Single point value	The value at a certain frequency point in the result of the frequency response curve is generally used as a data point at 1kHz. It can effectively measure the working efficiency of the speaker under the same input power.
