Even though the single shock absorber can effectively reduce the noise and satisfy most of users, but noise could happened when users use microphones in extreme conditions.
While driving a car on rough roads, it shakes badly. The passengers feel the shakes because of the inertial forces, so often a suspension system is added between the car and tires. The suspension is like a spring. Its elasticity property helps balance the shaking car and decrease the vibrating energy. Based on this motion pattern, we add double shock absorbers between the capsule and handle. When the shakes occur, the system keeps the microphone in a balance status, and minimizes vibrations. In addition, the absorbers are screwed onto the handle, so the absorbing function is less affected even the microphone is used improperly.
The shock absorbers are made of soft elastomer, to make the shock absorbers with elasticity, considering the hardness while choosing materials.
