Diaphragm and back-electret microphones are two common types of microphones, each with distinct characteristics in terms of structure, sound quality, feedback suppression, cost, and applications.
1. Structure
The diaphragm microphone captures sound by channeling it through the diaphragm to the electromagnetic coil at the back, whereas the back-electret microphone directs sound directly to the front electromagnetic coil.
2. Sound Quality
Diaphragm microphones typically offer more transparent and detailed sound quality compared to back-electret microphones. They excel in capturing subtle details and a broad dynamic range, making them popular choices in recording studios and professional performance settings.
On the other hand, back-electret microphones are better suited for high-volume environments such as stage performances and large concerts, where their sound is brighter and more direct.
3. Feedback Suppression
Thanks to their structure, diaphragm microphones are less sensitive to sounds from the rear, providing better feedback suppression in settings like stage performances where high feedback can be an issue.
Back-electret microphones, being relatively more sensitive, are more susceptible to feedback from rear sounds.
4. Cost and Applications
Diaphragm microphones are generally more expensive, making them suitable for professional recording and performance environments. Back-electret microphones are comparatively more affordable and are well-suited for standard recording and stage performance scenarios.
Note: When selecting a microphone type, it's essential to consider the specific application and setting requirements. Each type has unique characteristics and usage contexts, so choosing the right one depends on your needs.
