In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is described in further detail.Should be appreciated that embodiment described herein, only in order to explain the present invention, does not limit protection scope of the present invention.
Each Blu-ray player has maximum and minimum value that can output volume, i.e. volume control range, and common value is 0-100.
The method for controlling volume of Blu-ray player of the present invention, relates to four volumes altogether: max volume (max volume), output volume (volume), earpiece volume (earphones volume) and opening sound volume (power on volume).The volume of exporting when wherein output volume refers to Blu-ray player normal play, the volume of exporting when earpiece volume refers to plugged earphone, the output volume of acquiescence after opening sound volume refers to start shooting.Traditional Blu-ray player does not add differentiation to this three, and unified control, causes and change a kind of occasion, and volume is with regard to inappropriate situation.This method is separately controlled these three kinds of volumes, meets user's demand.Max volume is equivalent to a threshold value, to avoid the excessive infringement of output volume and opening sound volume user's the situation such as loudspeaker.The concrete control procedure of this method as shown in Figure 1, comprises the following steps.
Step s101, the volume control range of determining Blu-ray player, max volume and output volume, and obtain earpiece volume in the time having earphone to insert Blu-ray player, in the time that starting shooting, obtains Blu-ray player opening sound volume;
Step s102, judge the size of described output volume, in the time being greater than described max volume, turned down, make it be no more than described max volume;
Step s103, when there being earphone to insert when Blu-ray player, cancel the restriction of described max volume, in described volume control range, regulate earpiece volume;
Step s104, in the time that Blu-ray player is started shooting, using the volume before shutdown as opening sound volume, or the volume that user is arranged is as opening sound volume, the opening sound volume arranging as user while being greater than described max volume, is turned down, makes it be no more than described max volume.
For max volume, user on Blu-ray player, click max volume this, eject corresponding window, user carries out the setting of max volume, this value is decided to be max_vol, default value is 100, when user regulates max volume, if when current max_vol is less than output volume, output volume vol also diminishes as max_vol, in like manner opening sound volume, if the max_vol that user arranges is less than the opening sound volume that user oneself arranges, opening sound volume also diminishes as max_vol.
Output volume vol is the most basic volume control, and the output volume acquiescence from 0 to 100 of disc player, is still subject to the control of max volume, vol>=0 and vol<=max_vol.
