Latest Patents

One of Zhen Dong's notable inventions is the **Compact Low-Frequency Wave Absorption Device**. This device employs the rotational translation of an inertial mass rotor to provide damping for low-frequency noise and vibrations. The axial component translates the linear movement of a displaceable member into the rotational movement of the rotor, creating an inertial amplification effect. This innovative approach allows for a compact assembly designed to capture and absorb light ultra-low frequency resonances efficiently.

Another significant invention is the **Soft Acoustic Boundary Plate**, which introduces a soft boundary structure with a resonator capable of receiving sound or vibration. This resonator establishes resonance in conjunction with the incoming sound or vibration, leading to a reflection characterized by a pi phase factor. The soft boundary, located in proximity to the resonator structure, collaborates effectively to attenuate sound or vibration, illustrating Zhen Dong's expertise in acoustic attenuation technology.
