Microphone with internal damping |
摘要 |
Method and apparatus are disclosed for damping the resonance frequency in a microphone. The method and apparatus of the invention involve providing an elastomeric frame to support the backplate. The elastomeric frame forms a substantially air tight seal around the backplate. A hole is formed in the backplate and a cover having an opening therein is placed over the hole in the backplate. The frequency response of the microphone may then be controlled by precisely controlling the size, shape, and/or location of the opening in the cover overlaying the hole. The cover may also serve as an electrical contact to other components in the microphone. |
