The smart speaker is a product of a speaker upgrade. It is a tool for home consumers to use voice to surf the Internet, such as on-demand songs, online shopping, or understanding the weather forecast. It can also control smart home devices, such as opening curtains and setting refrigerators. Temperature, let the water heater heat up in advance, etc. But what should we do if we want to apply for EMC testing for this wireless smart product? Let's take a look together!

What is EMC testing?

EMC testing is also called electromagnetic compatibility (EMC), which refers to the comprehensive evaluation of the electromagnetic field interference (EMI) and anti-interference ability (EMS) of electronic products. It is one of the most important indicators of product quality. The measurement of electromagnetic compatibility is determined by The test site and test equipment are composed. The purpose of EMC testing is to detect the influence of electromagnetic radiation generated by electrical products on the human body, the power grid in public places, and other electrical products that work normally.

Smart speaker EMC test items-EMI (electromagnetic interference) test + EMS (electromagnetic sensitivity) test

EMI test items include:
