Electret Microphones

Engineered to perfection, our ECM and miniature electret microphones offer exceptional clarity and precision, with custom options to match your unique product requirements.

Tight Sealing

Advanced automated sealing technology ensures each microphone component is tightly sealed, effectively preventing external noise interference and enhancing product stability and reliability.

Secure Soldering

Precision soldering techniques ensure each solder joint is secure, reducing the risk of poor contact and disconnection, guaranteeing long-term stable operation.

Multi-Interface Support

Our production line supports traditional pin soldering and can also provide solder joint and wire interfaces based on customer requirements, adapting to different design needs.

Quality Standards & Assurance

21 Parameter Tests

We conduct 21 parameter tests to ensure the highest quality standards are met.

18 Quality Control Steps

18 quality control steps provide products you can trust, with a defect rate controlled at less than 0.1%.

Durability and Stability Testing

Products undergo rigorous testing, including 12 hours of aging at 80°C, 1-meter drop tests, and salt spray and humidity tests, ensuring product stability.

Mean Time To Failure (MTTF)

Mean Time To Failure (MTTF) <10PPM, ensuring high product reliability.

Eco-Certifications

Eco-friendly materials are uniformly sourced, compliant with ROHS standards.

Customization Options

Sensitivity Customization

The ability to generate voltage under unit sound pressure is a key parameter. Custom range: -22dB to -70dB.

Frequency Customization

The frequency range that the audio system can reproduce within the allowed amplitude. Custom range: 20Hz to 20KHz.

Signal-to-Noise Ratio (S/N) Customization

The ratio of MIC sensitivity to its inherent noise under the same conditions. S/N should generally not be lower than 70dB.

Testing Options

High-Temperature Testing
