Abstract: There is provided a noise reduction headset having multi-microphone and a noise reduction method. One embodiment of the headset includes a headband and headset bodies respectively connected to both ends of the headband, wherein the headset further includes a microprocessor and at least three microphones disposed on an outer surface of the headset body; the microprocessor is configured to select the microphone closest to a target sound source as a main microphone according to a comparison of sound signals picked up by respective microphones, select the microphone farthest from the main microphone as an auxiliary microphone according to a preset relative position of respective microphones, and execute a noise reduction algorithm by using a first sound signal picked up by the main microphone and a second sound signal picked up by the auxiliary microphone as inputs of the noise reduction algorithm so as to realize noise reduction. According to the embodiment, the noise reduction performance can be ensured under the condition that the user does not wear the headset normally.

Abstract: A linear vibration motor, comprising a stator assembly and a vibrator assembly. The stator assembly comprises a housing (1) having a receiving cavity, a magnet (2) located in the receiving cavity and jointly fixed to the housing (1), and a central magnetic yoke (3) of which at least one end is jointly fixed to the housing (1). The magnet (2) comprises a hollow portion (21) extending along the vibration direction of the vibrator assembly. The vibrator assembly comprises a coil (4) and a mass block (9). When the vibrator assembly vibrates, the coil (4) vibrates along with the vibrator assembly and is inserted into the hollow portion (21) of the magnet (2). The central magnetic yoke (3) runs through the coil (4). An resilient support member (5) is configured to suspend the vibrator assembly in the receiving cavity of the housing (1). According to the linear vibration motor, the magnetism of the magnet can be utilized to the greatest extent, thereby improving the efficiency of utilizing the magnetic line of force of the magnet by the coil, the central magnetic yoke functions as a guide shaft, thereby ensuring the vibration coaxiality of the vibrator assembly.

Abstract: A positioning method and an electronic device are provided. The method comprises: acquiring azimuth angle data collected by a first sensor and acceleration data collected by a second sensor respectively (101); judging whether a turning event occurs at a current moment based on the azimuth angle data and the acceleration data (102); and if a turning event occurs, generating a positioning request to acquire position data of the current moment based on the positioning request for positioning and displaying (103). In the method, the positional change caused by a turning action is identified and positioned, so that a motion trajectory displayed in a map reflects the actual movement more truly.

Abstract: A near-eye display device and an eye tracking system for the near-eye display device are provided. The eye tracking system includes a processor, a control analysis device, an LED illuminating device, a DMD display device and an IR camera. The processor outputs a video signal corresponding to a video displayed on the near-eye display device to the control analysis device. The control analysis device generates an LED synchronization signal and a corresponding subfield display signal. The LED illuminating device drives an LED to emit light, and transmits the light emitted from the LED into the DMD display device. The DMD display device reflects the light into a lens to form an image, and projects the image onto an eye. The IR camera captures an eye image. The control analysis device acquires the eye image and analyzes the eye image to obtain gaze point information.
