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.

1. An electronic device comprising:
a sound collecting unit; and a processor to determine whether sound signals collected by the sound collecting unit comprises a first portion, a second portion, and a third portion in sequence in a continuous time period, the first portion and the third portion being generated when a human being exhales: the processor further to determine whether a first duration of the second portion falls within a first preset time range, wherein the first duration of the second portion indicates an interval between two exhalations; the processor further to determine whether a second duration of each of the first portion and the third portion falls within a second preset time range, and further to determine whether a frequency of each of the first portion and the third portion is greater than 300Hz when the second duration falls within the second preset time range, a function of the electronic device being triggered when the first duration falls within the first preset time range, and when the second duration falls within the second preset time range, and the frequency of each of the first portion and the third portion being greater than 300Hz.
