<p>The present invention provides a method and a device for automatically adjusting sound volume, wherein the method includes: detecting and acquiring magnitude of a current flowing through a loudspeaker and/or an earphone; quantizing the acquired magnitude of the current to acquire a quantized value of current audio; adjusting sound volume according to a comparison result between the quantized value of the current audio and a audio value which is set by a user. With the present invention, sudden change of sound volume caused by the change of music files or different music types can be effectively avoided, so as to protect hearing of the user and avoid the user from being frightened due to extremely high sound volume, thereby improving user experience.</p> |
