Claims

[Scope of utility model registration request]

A variable resonator device comprising a case having a resonance chamber attached to a duct through which engine intake or exhaust air flows, and a tuning pipe having one end opened into the duct and the other end opened inside the resonance chamber. A movable member capable of changing an inner diameter is provided at one end of the tuning pipe, and further includes an actuator that displaces the movable member to change the inner diameter of the one end of the tuning pipe. Variable resonator device.
