A dynamic microphone head, also known as a dynamic mic capsule, has several notable characteristics:
- Simple Structure and Stable Performance: It has a straightforward design, stable performance, and does not require a DC power supply to operate.
- Durability: The diaphragm is resistant to pressure, durable, and can withstand wear and tear.
- Good Directionality and Low Noise: It features excellent directionality and low noise, which helps in capturing sound from a specific direction.
- Feedback Resistance: Due to its relatively low sensitivity, the dynamic mic head is less prone to feedback.
- Natural Sound Quality: Compared to condenser microphones, dynamic microphones produce a natural, warm, and slightly muffled sound, making them advantageous in certain applications.
- High SPL Handling: It can handle high sound pressure levels, allowing it to manage loud volumes without being easily damaged.
- Flat Frequency Response: It offers a good frequency response, with a flat amplitude-frequency curve within the 50-15000Hz range.
- However, dynamic microphone heads also have some limitations. For instance, they are less sensitive to high-frequency details, which can result in insufficient high-frequency pickup.
- Additionally, the transient response of dynamic microphones is relatively slow, which might not capture rapidly changing sound details effectively.
Overall, dynamic microphone heads play a crucial role in applications such as recording drum kits in studios, karaoke microphones in KTVs, and live sound reinforcement. When choosing and using a dynamic mic head, it's essential to balance and consider these characteristics based on specific needs and scenarios.
