What Is a Microphone Capsule?
A microphone capsule is the sensing element that converts sound into an electrical signal. In embedded audio — voice assistants, conferencing, hearing aids, wireless headsets and smart devices — the capsule choice drives sensitivity, signal-to-noise ratio (SNR) and frequency response, which together decide how cleanly the device picks up speech.
SHENGQUN manufactures microphone capsules and modules as an OEM / ODM supplier. The line includes MEMS capsules with 62 dB SNR, electret condenser capsules from 6–34 mm, and dynamic/condenser capsules rated around -30 dB sensitivity.
Specifications to Compare
- Signal-to-noise ratio (SNR). Higher SNR means quieter background hiss — a key spec for voice assistants.
- Sensitivity. Typical capsule sensitivity around -30 dB determines output level vs. amplifier gain.
- Size and package. MEMS capsules are very small; electret condensers range from 6–34 mm.
- Directivity. Omnidirectional vs. cardioid/bidirectional patterns for the target placement.
- Terminal type. SMD packages for automated assembly vs. leaded capsules for manual mounting.
How to Select a Microphone Capsule Supplier
- Define the voice capture target. Far-field vs. near-field, desired SNR and sensitivity.
- Set the mechanical envelope. Acoustic hole, package height and wiring/terminal.
- Choose MEMS vs. electret condenser. Match technology to assembly and cost targets.
- Validate with samples. Record real speech in your device and enclosure.
- Confirm compliance and supply. RoHS/REACH and long-term availability for your product lifecycle.
