Abstract

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.

Claims

1. An electronic device comprising:

a sound collecting unit; and

a processor to determine whether continuous sound signals collected by the sound collecting unit comprises a first alternating portion, a direct portion, and a second alternating portion in sequence, determine whether a first duration of the direction signals portion falls within a first preset time range, determine whether a second duration of each of the first alternating portion and the second alternating portion falls within a second preset time range, and trigger 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.

2. The electronic device as described in claim 1, wherein the first preset time range is 100 ms-2.5 s, and the second preset time range is 100 ms-2.5 s.

3. The electronic device as described in claim 1, wherein the first preset time range is 200 ms-500 ms, and the second preset time range is 200 ms-500 ms.

4. The electronic device as described in claim 1, wherein the processor is further to determine whether a frequency of each of the first alternating portion and the second alternating portion is greater than a preset value when the second duration falls within the second preset time range, and trigger a function of the electronic device when the frequency of each of the first alternating portion and the second alternating portion is greater than the preset value.

5. The electronic device as described in claim 4, wherein the preset value is 300 Hz.

6. The electronic device as described in claim 4, wherein the preset value is 800 Hz.

7. The electronic device as described in claim 1, further comprising:

a filtering and magnifying circuit to filter and magnify the sound signals collected by the sound collecting unit; and

a decoding circuit to decode the magnified sound signals and output the decoded sound signals to the processor.

8. An electronic device comprising:

a sound collecting unit;

a storage unit to store reference signals, the reference signals comprising a first reference alternating portion, a reference direct portion, and a second reference alternating portion in sequence; and

a processor to determine whether continuous sound signals collected by the sound collecting unit comprises a first alternating portion, a direct portion, and a second alternating portion in sequence, determine whether a first difference between durations of the reference direct portion and the direct portion falls within a first preset time range, whether a second difference between durations of the first reference alternating portion and the first alternating portion falls within a second preset time range, and whether a third difference between durations of the second reference alternating portion and the second alternating portion falls within the second preset time range, and trigger a function of the electronic device when the first difference falls within the first preset time range, and the second difference and the third difference falls within the second preset time range.

9. The electronic device as described in claim 8, wherein the processor is further to determine whether a first frequency difference between the first reference alternating portion and the first alternating portion falls within a preset frequency range, and whether a second frequency difference between the second reference alternating portion and the second alternating portion falls within the preset frequency range, and trigger a function of the electronic device when the first frequency difference and the second frequency difference fall within the preset frequency range.

10. A method for triggering a function of an electronic device, the electronic device comprising a sound collecting unit, the method comprising:

determining whether continuous sound signals collected by the sound collecting unit comprises a first alternating portion, a direct portion, and a second alternating portion in sequence;

determining whether a first duration of the direction signals portion falls within a first preset time range, and whether a second duration of each of the first alternating portion and the second alternating portions falls within a second preset time range; and

triggering 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.

11. The method as described in claim 10, wherein the first preset time range is 100 ms-2.5 s, and the second preset time range is 100 ms-2.5 s.

12. The method as described in claim 10, wherein the first preset time range is 200 ms-500 ms, and the second preset time range is 200 ms-500 ms.

13. The method as described in claim 10, further comprising:

determining whether a frequency of each of the first alternating portion and the second alternating portion is greater than a preset value when the second duration falls within the second preset time range; and

triggering a function of the electronic device when the frequency of each of the first alternating portion and the second alternating portion is greater than the preset value.

14. The method as described in claim 13, wherein the preset value is 300 Hz.

15. The method as described in claim 13, wherein the preset value is 800 Hz.
