Abstract

The present disclosure provides an impedance device and a system for simulating an impact of a head on a vibration of a vibration unit. The impedance device may include a mass part, an elastic part, and a fixing part. The mass part is connected to the fixing part through the elastic part. The fixing part is a hollow structure, the fixing part includes an opening. The elastic part is located at the opening and is connected to the fixing part. The elastic part forms a cavity with the fixing part. An elastic coefficient of the elastic part of a vibration direction in which the mass part vibrates relative to the fixing part in a range of 600 N/m~5000 N/m.
