The operating voltage requirement for electret microphone capsules (also known as electret mic elements or mic heads) typically depends on the specific model, design, and specifications set by the manufacturer.
Generally, the normal operating voltage range for electret microphone capsules is between 1.0V and 10V, with 2V to 5V being the most commonly used range in various electronic products.
It's essential to note that different models and brands of electret microphone capsules may have unique voltage requirements. Therefore, when choosing and using a capsule, you should refer to the manufacturer's product specifications or datasheet to ensure you supply the correct voltage.
Additionally, electret microphone capsules usually require a bias voltage to keep their internal circuitry operational. This bias voltage can either be provided by an external circuit or generated by an integrated circuit within the mic element itself.
In summary, while the required voltage range for electret microphone capsules varies depending on their model, design, and manufacturer's specifications, ensuring the correct voltage is applied is crucial to avoid damage or performance issues.
