Microphone shield system |
摘要 |
A microphone shield system captures sound in adverse conditions. The system includes a microphone positioned within an enclosure. A membrane stretched across a portion of the enclosure passes signals within a selected frequency range. The membrane may block or attenuate signals above and/or below the frequency range to pass a desired sound with little surrounding interference.
