摘要： Described herein are an ultrasonic positioning system integrated in an electronic device, and a method using the same. The ultrasonic positioning system comprises an ultrasound generator, two or more ultrasound receivers, and a control unit. Said ultrasound generator is configured to generate an ultrasound wave. Said two or more ultrasound receivers are configured to receive a reflected ultrasound wave produced by reflection of the ultrasound wave by an object in a field. Said control unit is configured to determine a position and/or a speed of the object using a frequency shift or a delay or both of the reflected ultrasound wave relative to the ultrasound wave. The ultrasonic positioning system provides gesture recognition and non-contact control of the device based on the ultrasonic positioning function of the device.

摘要： The present application provides an intelligent device, an intelligent speaker, and a method and system for controlling the same. The intelligent device includes a first sound detection module configured to detect a first sound signal directly reaching the first sound detection module; an angle determination module configured to determine a time difference between the receiving time of the first sound signal and the receiving time of the second sound signal, and determine a relative angle between the intelligent device and the intelligent speaker based on a distance between the first sound detection module and the second sound detection module and the time difference; and a transmitting module configured to transmit a notification message containing the relative angle to the intelligent speaker, so that the intelligent speaker directionally transmits a sound to the intelligent device based on the relative angle. Directional sounding based on relative angle calculation is realized.
