Dynamic and condenser microphone capsules are often used in different applications due to differences in their acoustic structure, working principle, and material composition.
Dynamic Microphone Capsule Features
- Generally, dynamic microphone capsules are larger in size, heavier, and have lower sensitivity.
- They typically do not require circuit coordination and can complete audio transmission with just simple amplification circuitry, making them cost-effective.
- Although the frequency response range is narrower, it is sufficient for the human voice range, with rich low frequencies, more distortion, and a generally warmer sound quality.
- Dynamic microphone capsules are passive devices, so there is no concept of signal-to-noise ratio (SNR), and they are more resistant to interference.
- They are highly adaptable to various temperature and humidity environments and are better at resisting vibrations.
Condenser Microphone Capsule Features
- Condenser microphone capsules are generally smaller, lighter, and have higher sensitivity, with relatively lower costs for individual units.
- They require circuit coordination, including different power supply methods, for polarization, impedance conversion, and audio amplification.
- Condenser capsules have more complex circuitry, which makes them more expensive to use. They offer flat frequency response with a wider range.
- Low frequencies can sound dry, high frequencies are more delicate, with less distortion. Overall sound is more accurate, and the SNR varies depending on the circuit configuration.
- Condenser capsules are more susceptible to interference and less resilient to environmental changes like temperature and humidity, as well as vibrations.
In summary, dynamic microphone capsules do not require power supply, polarization, or impedance conversion circuitry, making them more cost-effective and efficient in production compared to condenser microphone capsules.
