AI Technical Summary
Technical Problem
In compact electronic devices, the formation of a resonant cavity negatively impacts microphone performance, especially when the gaps between housing components are closed, leading to a decrease in frequency response.
Method used
By placing damping materials and resonators, such as Helmholtz resonators, near the microphone, the resonance effect can be improved, the formation of resonant cavities can be prevented, and the microphone performance can be improved at multiple frequencies.
Benefits of technology
It effectively reduces or eliminates the negative impact of the resonant cavity on the microphone, improving the microphone's frequency response and audio quality.
