Latest Patents

One of Yu Du's latest patents is for a digital microphone noise attenuation device. This innovative digital microphone includes circuitry designed to minimize noise caused by idle tone frequency components in the digital signal output. In stereo mode and other scenarios where interference may occur between multiple microphones, each device features a digital output with a corresponding idle tone frequency. One of these frequencies is offset to shift noise components outside the desired frequency range, thereby improving sound clarity.

Another notable patent is for an acoustic assembly that incorporates an acoustically permeable membrane. This acoustic device features a motor housed within a non-porous elastomeric membrane that spans an acoustic path defined by a sound port. The motor can be a MEMS transducer, which generates an electrical signal in response to an acoustic signal. The membrane is designed to prevent contaminants from entering while allowing acoustic signals to propagate with minimal loss.
