Abstract

A removable case for a mobile communications device includes an opening that aligns with a microphone port that is built into the device. The case includes a windscreen that is sealed across the opening of the case. The windscreen is designed to reduce wind noise, air blasts, vocal plosives, and other noise. Other embodiments are also described and claimed.

Claims

1. An apparatus, comprising:

a removable case for a handheld mobile communications device having a windscreen sealed across an opening of the case, wherein the opening aligns with a microphone port that is built into the device.

2. The apparatus of claim 1, wherein the case is formed from at least one of plastic, acrylic, polycarbonate, silicon, or rubber.

3. The apparatus of claim 1, wherein the windscreen has a structure that includes at least one of a mesh structure, a foam structure, or a feather-like structure.

4. The apparatus of claim 1, wherein the windscreen is adhesively attached to an interior side of the case so as to extend across the opening.

5. The apparatus of claim 1, wherein the windscreen is embedded in a wall of the case so as to extend across the opening.

6. The apparatus of claim 1, wherein the windscreen is molded integrally into the case so as to extend across the opening.

7. The apparatus of claim 1, wherein the windscreen reduces susceptibility of a microphone to wind noise.

8. The apparatus of claim 1, wherein the windscreen prevents moisture, dirt, or dust from entering the microphone port.

9. A removable case for a handheld mobile communications device, comprising:

an opening that aligns with the device'"'"'s built-in microphone port; and

a windscreen that fills the opening.

10. The removable case of claim 9, wherein the case is formed from at least one of plastic, acrylic, polycarbonate, silicon, or rubber.

11. The removable case of claim 9, wherein the windscreen has a structure that includes at least one of a mesh structure, a foam structure, or a feather-like structure.

12. The removable case of claim 9, wherein the windscreen is adhesively attached to an interior side of the case so as to extend across the opening.

13. The removable case of claim 9, wherein the windscreen is embedded in a wall of the case so as to extend across the opening.

14. The removable case of claim 9, wherein the windscreen is molded integrally into the case so as to extend across the opening.

15. The removable case of claim 9, wherein the windscreen reduces susceptibility of a microphone to wind noise.

16. The removable case of claim 9, wherein the windscreen prevents moisture, dirt, or dust from entering the microphone port.

17. A method, comprising:

forming a removable case for a handheld mobile communications device, wherein the removable case includes an opening that aligns with the device'"'"'s built-in microphone port; and

incorporating a windscreen into the case, wherein the windscreen fills the opening of the case.

18. The method of claim 17, wherein forming the case includes forming the case from at least one of plastic, acrylic, polycarbonate, silicon, or rubber.

19. The method of claim 17, wherein incorporating the windscreen includes incorporating a structure that includes at least one of a mesh structure, a foam structure, or a feather-like structure.

20. The method of claim 17, wherein incorporating the windscreen includes adhesively attaching the windscreen to an interior side of the case so as to extend across the opening.

21. The method of claim 17, wherein incorporating the windscreen includes embedding the windscreen in a wall of the case so as to extend across the opening.

22. The method of claim 17, wherein incorporating the windscreen includes integrally molding the windscreen into the case so as to extend across the opening.

23. The method of claim 17, wherein the windscreen reduces susceptibility of a microphone to wind noise.

24. The method of claim 17, wherein the windscreen prevents moisture, dirt, or dust from entering the microphone port.
