Microphone shield system
View Patent ↗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.
1. A microphone shield system comprising:
a microphone enclosure;
an enclosure neck extending from the microphone enclosure;
a membrane stretched across the enclosure neck; and
a membrane support positioned across the enclosure neck.
2. The microphone shield system of claim 1 , where the membrane is stretched by an inflated pressure, where the inflated pressure exceeds an atmospheric pressure.
3. The microphone shield system of claim 1 , the membrane comprising a mechanically stretched membrane.
4. The microphone shield system of claim 1 , the membrane comprising a mechanically stretched membrane inflated above atmospheric pressure.
5. The microphone shield system of claim 1 , where the membrane support comprises a wire mesh support.
6. The microphone shield system of claim 1 , where the membrane passes about 100 Hz to about 10 KHz.
7. The microphone shield system of claim 1 , where the membrane passes about 300 Hz to about 5 KHz.
8. The microphone shield system of claim 1 , further comprising a foam layer positioned above the membrane.
9. The microphone shield system of claim 1 , further comprising a fastener coupled to the membrane that attaches the membrane to the microphone enclosure above the membrane support.
10. A microphone shield system comprising:
a microphone enclosure;
an enclosure neck extending from the microphone enclosure; and
a membrane stretched across the enclosure neck by an inflated pressure, where the inflated pressure exceeds an atmospheric pressure.
11. The microphone shield system of claim 10 , further comprising a membrane support positioned across the enclosure neck.
12. The microphone shield system of claim 11 , the membrane support comprising a wire mesh support.
13. The microphone shield system of claim 10 , where the membrane passes about 100 Hz to about 10 KHz.
14. The microphone shield system of claim 10 , where the membrane passes about 300 Hz to about 5 KHz.
15. The microphone shield system of claim 10 , further comprising a foam layer positioned above the membrane.
16. The microphone shield system of claim 10 , where the inflated pressure is greater than or equal to an expected environmental pressure.
17. A microphone shield system comprising:
a microphone enclosure;
an enclosure neck extending from the microphone enclosure; and
a membrane stretched across the enclosure neck, the membrane comprising a mechanically stretched membrane inflated above atmospheric pressure.
18. The microphone shield system of claim 17 , further comprising a membrane support positioned across the enclosure neck.
19. The microphone shield system of claim 18 , where the membrane support comprises a wire mesh support.
20. The microphone shield system of claim 17 , where the membrane passes about 100 Hz to about 10 KHz.
21. The microphone shield system of claim 17 , where the membrane passes about 300 Hz to about 5 KHz.
22. The microphone shield system of claim 17 , further comprising a foam layer positioned above the membrane.
23. The microphone shield system of claim 17 , where the mechanically stretched membrane is inflated above an expected environmental pressure.
