MEMS Microphone from United States
A MEMS microphone that converts sound waves into electrical signals using a semiconductor diaphragm and backplate, forming a capacitive transducer. It is a semiconductor-based transducer because it converts an acoustic phenomenon into an electrical signal, and it is supplied as a discrete component for audio devices.

Import Tips
• Classify MEMS microphones as semiconductor-based transducers if they consist of the MEMS element and basic packaging
• If the microphone includes an integrated amplifier or analog-to-digital converter, it may be an integrated circuit under 8542
• Provide the microphone's technical specifications to customs to confirm the classification
