Patent ID: 8682384

Claim:
A volume adjusting method for a mobile terminal, comprising the following steps of: acquiring a noise pressure signal from surroundings of the mobile terminal, and converting the noise pressure signal acquired in an analog form into a noise pressure signal value of a digital form once every 200 milliseconds; comparing a volume value corresponding to the acquired noise pressure signal with a volume control value currently set in the mobile terminal; adjusting the volume control value of the mobile terminal according to the comparison result; and controlling a volume level of the mobile terminal according to the volume control value that has been adjusted; wherein an analog-to-digital conversion is carried out once every 200 milliseconds on the noise pressure signal; wherein the noise pressure signal is continuously acquired 5 times every 200 milliseconds to obtain five noise pressure signal values; and a maximum value and a minimum value are removed to calculate an average value of the left three values as a noise pressure signal value of the current surroundings.
