ELECTRONIC DEVICE AND METHOD FOR TRIGGERING FUNCTION OF ELECTRONIC DEVICE

摘要

An electronic device includes a sound collecting unit and a processor. The processor determine whether continuous sound signals collected by the sound collecting unit includes a first alternating portion, a direct portion, and a second alternating portion in sequence. The processor further determines whether a first duration of the direction signals portion falls within a first preset time range, and determines whether a second duration of each of the first alternating portion and the second alternating portion falls within a second preset time range. The processor then triggers a function of the electronic device when the first duration falls within the first preset time range, and the second duration falls within the second preset time range. A related method is also disclosed.
