Fengyun Liao

Fengyun Liao is a Shenzhen-based inventor who has a total of 100 patents under his name. His latest inventions cater to audio technology, with emphasis on sound suppression and bone conduction speakers.

One of his latest patents is the "Systems and methods for suppressing sound leakage", which describes a speaker that is designed with at least one sound guiding hole that leads the sound wave inside the housing through to the outside of the housing. This guided sound wave is utilized to interfere with the leaked sound wave, helping effectively suppress the sound leakage. The effectiveness of this interaction is greatly dependent on the distance between the sound guiding hole and the portion of the housing.

Another noteworthy invention by Liao is the "Bone conduction speaker and compound vibration device thereof". This patent introduces a bone conduction speaker comprising a vibration conductive plate and vibration board, which are intricately aligned using at least two adjustable first and second rods that converge to the center of their respective torus structures. The vibration conductive plate is fixed with the vibration board, and the second torus has a fixed voice coil that is driven by the magnetic system, providing an overall compound vibration device with a flatter frequency response and broader sound.

Fengyun Liao was affiliated with SHENZHEN SHOKZ CO., LTD. and Shenzhen Voxtech Co., Ltd. where he collaborated with many fellow inventors, including Xin Qi and Lei Zhang.
