Abstract

Provided are a method and device for adjusting a call volume and a mobile terminal, wherein the method includes detecting gravity location information of a terminal when a given detection time is reached, and adjusting a current call volume in accordance with a given volume adjustment rule when the gravity location information and gravity location information obtained by last detection are separately located on two sides of a pre-set gravity zero line. The application of the present disclosure solves a problem in the related art that a user in a call using a left ear and a right ear alternatively usually needs to continuously adjust volume of an earphone manually because there is a hearing difference between the left ear and the right ear, which results in much inconvenience when answering a call, and thus the call volume during a call can be automatically adjusted, a performance of the mobile terminal is enhanced and user experience is improved.

2. The method according to claim 1 , further comprising: before adjusting the current call volume in accordance with the given volume adjustment rule,
judging whether a distance between the terminal and a user's head exceeds a pre-set distance threshold in a period of time from last detection time to this detection time, and adjusting the call volume of the terminal in a situation that the distance exceeds the pre-set distance threshold.

3. The method according to claim 1 , wherein the two sides of the gravity zero line comprise a left-side area and a right-side area of the gravity zero line, wherein values in the left-side area and the right-side area are not positive simultaneously, or values in the left-side area and the right-side area are not negative simultaneously.
