Ricoh MP C3004 - Helmholtz Silencer

Helmholtz silencer
The Helmholtz silencer applies the resonance phenomenon called the "Helmholtz resonance" to emit a
sound having reverse phase of the motor frequency by resonance and cancel the motor noise.
On this machine, it is located on the controller box side to reduce the noise. The BCU [B] is mounted on
the mold [A] of the Helmholtz silencer.
