It is reported that the U.S. Trademarks and Patent Office today issued an Apple new earphone patent application. This headset can reduce noise and identify user speech.
According to Apple, the headset is wired, with a variety of sensors built in, including an accelerometer and two microphones. The sensor is specifically designed to detect vibrations generated by the user. Whether it is a voiced sound produced by the user's vocal cords or an unvoiced sound that is not generated using the vocal cords, the sensors can be detected through vibrations in the tissues and bones. After the acceleration sensor is triggered, the detected vibration data is integrated into the front and rear microphones to determine the user's state and form a noise suppression system. After the collected speech data is processed by the noise reduction circuit, the background noise can be eliminated by an effective beamforming technique.
In addition, the Macbook already uses similar beamforming microphone technology, and Earpods headsets already have the ability to support this technology.
The silicon powder is used as a raw material, and the desired shape is first formed by a usual molding method, and preliminary nitriding is performed in a nitrogen gas at a high temperature of 1200 ° C, and a part of the silicon powder is reacted with nitrogen to form silicon nitride, and the entire billet is then formed. The body already has a certain strength. Then, a second nitriding is carried out in a high temperature furnace at 1350 ° C to 1450 ° C to form a silicon nitride. A silicon nitride having a theoretical density of 99% can be obtained by a hot press sintering method.
