Audio Switch
Audio switch box, used to expand the input/output capability of dual-channel audio analyzers. It can extend 2 input/output channels to any two of the 12 input/output channels, avoiding the need for cable plugging and unplugging due to interface changes during multi-channel product testing, thereby improving testing efficiency.

Artificial Ear 318
The EA01/02 artificial ear (318) simulates the acoustic characteristics of the human ear and is a device specifically designed to measure the acoustic performance of headphones, receivers, and telephone receivers. It fully complies with the requirements of IEC60318 and ITU-T P.51 standards and mainly includes the IEC60318 acoustic coupling cavity, 1/2-inch pressure field microphone and preamplifier, and base.

Artificial Ear Test Stand
The artificial ear testing kit is designed specifically for headphone testing and comes in two models: TF01 and TF02. TF01 is a 711 artificial ear kit, consisting of a testing stand and two 711 artificial ears (including soft ears), mainly used for testing earplug and in ear headphones. TF02 is a 318 artificial ear kit, consisting of a test stand and two 318 artificial ears (including tablets), mainly used for testing headphones. TF01 and TF02 need to be used in conjunction with the corresponding electroacoustic testing interface PA01 during the testing process. In addition, when paired with the artificial mouth AM02, they can also form a complete headphone acoustic testing kit, which can perform microphone testing in addition to headphone speaker acoustic testing.

Artificial Mouth AM02/02P/05
The AM02 series artificial mouth can accurately simulate the sound field generated by the human mouth in the near-field range, fully complying with international standards such as IEEE269 and ITU-T Rec. P51. It is specifically used for microphone acoustic characteristic testing of transmission and communication products such as telephones, mobile phones, and electroacoustic components. It has the characteristics of high stability and low distortion, making it an ideal sound source for microphone testing.
