Bone conduction single vibrator test
1、Overview:
Bone conduction is a way for sound waves to travel to the inner ear, traveling through the vibrations of the skull to allow yourself to hear sounds. Compared with ordinary human ears hearing the sound of the outside world through air transmission, bone conduction can achieve the noise filtering effect of air conduction in audio transmission.
1.1、Overview of bone conduction single vibrator
Bone conduction single vibrator is an important hearing method except air conduction transmission. Based on this method, many bone conduction hearing devices have been manufactured.
Then, for the performance test of the bone conduction single vibrator, we have a complete system from the software test algorithm to the hardware test equipment, which can quickly and accurately present the data of the bone conduction vibrator test items in a visualized manner.
2、Bone Conduction Single Vibrator Application Test:
Bone conduction single oscillator test items are: frequency response, thd, sensitivity, impedance, polarity, Rub&Buzz, etc.

2.2、Bone conduction monomer test link
Here is an example of bone conduction monomer test link:
The STINGER single-axis audio test platform pushes the signal to make the single-axis vibrator vibrate, and the ACC 1821 single-axis accelerometer cooperates with the custom fixture to collect the vibration signal to the PM 8023 audio data collector, and then transmits the collected signal back to the STINGER single-audio test platform for testing signal analysis.
