3722 Silicon Microphone

The 3722 Silicon Microphone is engineered for consistent and clear sound performance in compact devices. With an omni-directional pickup pattern, wide 100Hz–10kHz frequency response, and high 130dB SPL handling, it captures detailed audio even in high-volume environments. Its small 3.76 × 2.24 × 1.1mm footprint is perfect for space-constrained designs, making it an excellent choice for wearables, voice-controlled systems, and miniaturized electronics.

 

• With a remarkable sensitivity range of -39 to -45 dB, the recorder assures absolutely perfect audio recordings.
• Omni-Directional Directivity captures sound from all directions, therefore creating a harmonic and balanced audio experience.
• Its frequency range, 100Hz to 10000Hz, makes it suitable for many different kinds of recording purposes.
• A small-scale design Its 3.76 x 2.24 x 1.1 mm measurements fit tiny electrical components exactly.
• Sound Pressure Level: The sound pressure level (SPL) could reach a maximum of 130dB if one wants clear sound even in loud circumstances.
• Thanks to a signal-to---- Noise ratio of 56dB, you might get amazing audio output with little background noise interference.

 

TWS (True Wireless Stereo Earbuds) The 3722 Silicon Microphone is a compact, cost-effective solution tailored for TWS earbuds. With its ultra-small 3.76 × 2.24 × 1.1mm footprint and omnidirectional pickup, it enables clear voice capture regardless of earbud orientation. Its wide 100–10,000Hz frequency response and sensitivity range of -39 to -45dB deliver reliable performance in voice commands and call scenarios. The microphone's high 130dB SPL handling makes it resistant to distortion during loud inputs, perfect for dynamic environments.

Camera / Video Device In camera and video applications, the 3722 Silicon Microphone provides dependable, space-saving audio capture. Its high maximum SPL of 130dB ensures distortion-free sound even in noisy scenes, while the omnidirectional directivity captures consistent audio from multiple directions. Ideal for compact devices such as webcams, action cams, and wearable cameras, it balances cost-efficiency with solid performance for voice and ambient sound recording.
