Angle determining method, electronic device, and chip system

An angle determining method, applied to a first electronic device, wherein the method comprises:

• sending first sound wave signals through a first group of loudspeakers;
• sending second sound wave signals through a second group of loudspeakers, wherein a time at which the first sound wave signals are sent through the first group of loudspeakers is different from a time at which the second sound wave signals are sent through the second group of loudspeakers, and/or wherein characteristics of the first sound wave signals are different from characteristics of the second sound wave signals;
• and
• receiving an actual angle between the first electronic device and a second electronic device from the second electronic device, wherein the actual angle is determined by the second electronic device based on a first possible angle value and a second possible angle value, the first possible angle value is determined based on a receiving result of receiving, through a microphone of the second electronic device, the at least two sound wave signals sent through the first group of loudspeakers, and the second possible angle value is determined by the second electronic device based on receiving, through the microphone of the second electronic device, the at least two sound wave signals sent through the second group of loudspeakers.

A first electronic device, comprising:

• a memory configured to store computer program code comprising computer instructions;
• a display;
• and
• one or more processors coupled to the memory and the display, wherein execution of the instructions by the one or more processors causes the electronic device to:
• send at least two sound wave signals through one or more loudspeakers;
• receive, through a microphone, at least two sound wave signals from a second electronic device, and determine a first receiving result of receiving the at least two sound wave signals;
• determine a first possible angle value between the second electronic device and the first electronic device based on the first receiving result;
• receive, from the second electronic device, a second possible angle value between the first electronic device and the second electronic device;
• determine an actual angle between the first electronic device and the second electronic device based on the first possible angle value and the second possible angle value, or send the first possible angle value to the second electronic device, and receive an actual angle between the first electronic device and the second electronic device from the second electronic device;
• and
• display the actual angle.
