Electronic device and related sound leakage prevention method

An electronic device, comprising:

• a memory storing computer programming instructions;
• and
• one or more processors coupled to the memory, wherein the one or more processors are configured to execute the computer programming instructions to cause the electronic device to performs a sound leakage prevention method by:
• when the electronic device is in a call, displaying a first interface on a display of the electronic device, receiving and responding to a preset operation of a user on a preset area in the first interface, and displaying a second interface, and receiving and responding to a touch operation on a first control in the second interface;
• receiving an initial audio signal through an audio processing unit of the electronic device, and determining a first-type audio signal and a second-type audio signal based on the initial audio signal, wherein the first-type audio signal includes M first audio signals, and the second-type audio signal includes N second audio signals;
• sending the first-type audio signal to a first-type array element of the electronic device, and sending the second-type audio signal to a second-type array element of the electronic device, wherein one audio signal corresponds to one array element, and wherein the first-type array element includes M first array elements, the second-type array element includes N second array elements, and M and N are integers greater than 0;
• outputting M first sound wave signals through the M first array elements in the first-type array element based on the corresponding first audio signals;
• and
• outputting N second sound wave signals through the N second array elements in the second-type array element based on the corresponding second audio signals, wherein the N second sound wave signals are used for superimposition and cancellation with the M first sound wave signals at a plurality of location points in a first preset area.
