The invention relates to an anti-monitoring active noise reduction structure for a built-in gyroscope of a mobile phone. The structure comprises a shielding sheet covering the gyroscope, a combined permanent magnet is arranged in the center of the top of the shielding sheet, a rolling sliding ball is arranged on the lower side of the combined permanent magnet, a plurality of inclined guide rails which are evenly distributed along the circumference are arranged below the rolling sliding ball, the ends, facing the center, of all the inclined guide rails are connected to the lower portion of the rolling sliding ball, the lower side of each inclined guide rail is provided with a guide electromagnet used for attracting the corresponding combined permanent magnet to move towards the outward end of the corresponding inclined guide rail, and the outward end of each inclined guide rail is provided with a vibration piece assembly. The anti-monitoring active noise reduction structure for the built-in gyroscope of the mobile phone is reasonable in design, simple in structure and high in safety, and the anti-monitoring active noise reduction structure covers the gyroscope, counteracts a human voice signal by sending out an anti-phase wave of the human voice signal, eliminates interference of the human voice signal on the gyroscope, and achieves the anti-monitoring purpose.
Description
technical field [0001] The invention relates to the technical field of mobile phones, in particular to an anti-monitoring active noise reduction structure for a built-in gyroscope in a mobile phone. Background technique [0002] The human voice signal of the mobile phone will interfere with the built-in gyroscope, causing the gyroscope to vibrate. By obtaining the vibration signal of the gyroscope and reversely restoring and reconstructing the voice information and audio signal through the algorithm, the human voice signal can be successfully stolen to achieve the purpose of monitoring. In the current situation, there is no good way to deal with this situation. Contents of the invention [0003] In view of this, the object of the present invention is to provide a safe, reliable, and practical anti-monitoring active noise reduction structure for the built-in gyroscope of a mobile phone, which can eliminate the interference of human voice signals to the gyroscope and achieve...
