Design and Simulation of the Microphone with Side-holes
Yuan Ning-yi · Journal of Jiangsu Polytechnic University · 2003
The microphone with side-holes was designed and simulated.On one hand,the hole made on side decreased the initial stress,and increased the mechanical sensitivity of the diaphragm.On the other hand,the side-hole reduced the lacuna damp,and enlarged the frequency range according to flat frequency response,without the hole in back-plate.Different from the microphone with back hole,the soft back-plate would be completely avoided in side-hole design.
