Efficiently reducing motor noise.
Available in a wide range of types, these dampers reduce motor noise and protect microphones.
Today’s video recording devices, such as digital still cameras and video cameras, are becoming more and more compact, and the sensitivity of their built-in microphones is increasing. This raises the importance of taking measures against internal noise generation. Yamauchi uses a wide range of materials to provide optimal microphone dampers for your products.
Controlling the hardness of the rubber material makes it possible for vibration-resistant dampers and insulators to effectively suppress vibration. Yamauchi sets the hardness in fine 5-degree steps across a wide hardness range of 3 to 60 (A). When selecting materials, the resonance point can also be freely controlled, so even after the component shape has been decided and the mold has been produced, tuning is still applicable to approach the ideal characteristics.
Products with excellent audio characteristics require countermeasures against a wide frequency range. Yamauchi grades its materials across a wide dynamic viscoelasticity range(tan δ)of 0.1 to 0.8. Covering this wide frequency range effectively suppresses vibration magnification.
