Abstract

The disclosure provides an electronic device and a method for adjusting volume adapted for the device. The electronic device defines at least two work modes. The method includes steps: determining whether one of the at least two work modes is selected; detecting a pulse frequency of a user in real time when one of the at least two work modes is selected; determining whether the pulse frequency is less than a reference value; and if the pulse frequency is less than the reference value, adjusting a volume according the selected work mode.

Claims

1. An electronic device defining at least two work modes, comprising:

a selection unit to select a work mode of the at least two work modes;

a detection unit to detect a pulse frequency of a user in real time;

a comparison unit to compare the pulse frequency with a reference value; and

an audio control unit to adjust a volume according to the selected work mode when the current pulse frequency is less than the reference value.

2. The electronic device as recited in claim 1, wherein a pulse frequency of the user when sleeping is defined as the reference value.

3. The electronic device as recited in claim 1, wherein the at least two work modes comprises a sleep mode and a power mode, the audio control unit turns down the volume in the sleep mode and turns up the volume in the power mode.

4. The electronic device as recited in claim 1, wherein the detection unit is a pulse sensor.

5. A method for adjusting volume adapted for an electronic device, the electronic device defining at least two work modes, the method comprising:

determining whether one of the at least two work modes is selected;

detecting a pulse frequency of a user in real time when one of the at least two work modes is selected;

determining whether the pulse frequency is less than a reference value; and

if the pulse frequency is less than the reference value, adjusting a volume according the selected work mode.

6. The method for adjusting volume as recited in claim 5, wherein a pulse frequency of the user when sleeping is defined as the reference value.

7. The method for adjusting volume as recited in claim 5, wherein the at least two work modes comprise a sleep mode and a power mode, the method further comprising:

turning down the volume in the sleep mode and turning up the volume in the power mode.
