Microphone Quality Control

ECMIC implements strict microphone quality control processes based on ISO 9001 standards, ensuring consistent quality, stable acoustic performance, and reliable performance for electret, MEMS, and dynamic microphone capsules.

Microphone Quality Assurance Process

Our quality management system covers incoming material inspection, production process control, and final product verification. These procedures help maintain stable microphone capsule performance and consistency throughout mass production.

Incoming Quality Control

Incoming Quality Control (IQC) inspections verify raw materials and components before production to ensure compliance with required specifications.

Process Quality Control

Process Quality Control (IPQC) monitors manufacturing procedures to maintain production stability and consistent microphone capsule performance.

Outgoing Quality Control

Outgoing Quality Control (OQC) verifies finished microphone capsules before shipment to ensure reliability and product consistency.

Microphone Acoustic Testing and Performance Verification

Acoustic testing is a critical part of ECMIC's microphone quality control process. Professional testing equipment is used to verify sensitivity, frequency response, impedance, background noise, and polar patterns.
