What are the microphone directivity

According to the conversion principle, microphones are generally divided into moving coil, capacitor, electret, aluminum ribbon and other types. This is the first issue we must consider when choosing a microphone, because different types of microphones have their unique performance and purpose, and the sound quality produced Not the same.

Dynamic microphones: Usually dynamic microphones have low noise, no need to feed power, easy to use, stable and reliable performance, and relatively cheap, but their transient response and high-frequency characteristics are not as good as condenser microphones. If you are a beginner, and the sound reception environment is poor, and the noise is loud, choosing a dynamic microphone is more appropriate.

Condenser microphone: Condenser microphone has the advantages of ultra-high sensitivity, fast transient response, extremely wide frequency response, ultra-low touch noise, etc., but it is relatively intolerant and afraid of falling and tide. If you have a very good radio environment and need to record high-quality vocal audio, then choose a condenser microphone.

Ribbon microphones: Most of the ribbon microphones do not require external power supply, and can record clear but slightly dim sound. They are often used artistically in recording studios. However, ribbon microphones are generally very fragile and their output is generally relatively low. Small, so it is better to use with a pre-amplifier.

Electret microphones: Electret microphones are widely used in handheld devices due to their low cost and miniaturization. Electret microphones with integrated FET preamplifiers can provide high performance. However, its output signal is relatively weak, and its ability to handle the maximum sound pressure is also weak.
