Abstract

The invention provides an ultrasonic location system and an electronic device with a locating function. The ultrasonic location system is arranged in the electronic device in an integrated mode and comprises an ultrasound generating element, at least two ultrasound receiving elements and a control unit, wherein the ultrasound generating element is used for generating ultrasound waves, the ultrasound receiving elements are used for receiving reflected waves generated when the ultrasound waves meet a reflector, and the control unit is used for determining the spatial position and / or the moving speed of the reflector according to the frequency shift and / or the delay of the reflected waves. The ultrasonic location system and the electronic device with the locating function reduce requirements for an application environment.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of information processing, and more specifically, relate to an ultrasonic positioning system and an electronic device with a positioning function. Background technique [0002] In today's information age, various information devices have emerged as the times require: fixed telephones and mobile phones for voice transmission; servers and personal computers for information resource sharing and processing; various TV sets for video data display, etc. wait. With the popularity of smart phones, tablet computers and flat-panel TVs, human-computer interaction has gradually become a new highlight in terms of convenient operation of such devices. At present, although the main input methods of such devices are still keyboards (including keyboard remote controls used in TVs), capacitive touch, etc.; Input (such as Apple's Siri), and gesture recognition control (such as Samsung's Galaxy serie...
