Abstract: An electronic component for an electronic device with a locking function and an unlocking method thereof are provided. The unlocking method includes: receiving a first sound extraction request by a first processing circuit when the electronic device is in a locked mode; determining, by the first processing circuit, whether a first voice input signal is received after receiving the first sound extraction request; determining, by the first processing circuit when the first processing circuit receives the first voice input signal, whether first voice data included in the first voice input signal matches first preset voice data; and transmitting, by the first processing circuit, the first voice input signal to the second processing circuit when the first voice data matches the first preset voice data, to trigger the second processing circuit to determine whether second voice data included in the first voice input signal matches second preset voice data.
