Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is the process flow diagram of volume adjusting method embodiment 1 of the present invention.As shown in Figure 1, the method comprises:
Step 101: when having detected sound signal and input or output, obtain the change of distance information between electronic equipment and the user;
When having detected sound signal and input or output, when for example the user uses electronic equipment to carry out voice call, can trigger step 101.
Can adopt range sensor to obtain distance between electronic equipment and the user, with the distance that gets access to after the change of distance with change before the distance that gets access to subtract each other, can obtain the change of distance value between electronic equipment and the user.Change of distance information is the carrier of expression change of distance value.Because in this programme, be that the angle with information flow is described, so the electric signal of the expression change of distance value in the transmission course is called change of distance information.Range sensor can be the sensor of finding range by light wave or sound wave.The principle of range sensor can be by emission short especially light pulse or acoustic signals, and measures this light pulse or acoustic signals from being transmitted into the time that is reflected by the object, by the survey time calculate and object between distance.
Among the application, can also adopt image acquisition units to obtain distance between electronic equipment and the user.The mobile phone that for example has camera, camera are exactly image acquisition units.The image that can arrive according to camera collection obtains the distance between electronic equipment and the user.For the electronic equipment with image acquisition units, the image calculation electronic equipment that collects by image acquisition units and the distance between the user can be saved as electronic equipment and set up the cost that range sensor improves.
Step 102: judge that whether change of distance value that described change of distance information represents is greater than zero; If so, execution in step 103; Otherwise, execution in step 104;
By can knowing in the step 101, the change of distance value be by the distance that gets access to after changing with change before the distance that gets access to subtract each other and obtain.Therefore, when the change of distance value greater than zero, represent that then the distance between electronic equipment and the user has increased; When the change of distance value less than zero (being negative value), represent that then the distance between electronic equipment and the user has reduced.
Step 103: the volume that increases described electronic equipment; Described volume comprises output volume, and/or the input volume;
Output volume, in the time of can being user's displaying video or audio frequency, the volume of the sound of electronic equipment output also can be user when carrying out voice call, the volume of the sound of electronic equipment output.The input volume can be that the user is when carrying out voice call, by the volume of the equipment such as microphone to the sound of electronic equipment import and export.
To increase output volume as example:
When having detected sound signal and input or output, obtain the change of distance information between electronic equipment and the user.Can adopt the distance between range sensor detected electrons equipment and the user, and obtain change of distance information.After the distance between electronic equipment and the user increases, if keep the original volume of electronic equipment, then the volume heard of user will reduce.Adopt this step, can call the volume control interface according to the change of distance value, increase the volume of described electronic equipment, the volume approximate constant that the user is heard.
The principle that increases the input volume is similar to above-mentioned principle, can make in the voice call process volume approximate constant that the user of the equipment of the other end receives.
Step 104: the volume that reduces described electronic equipment.
To reduce output volume as example:
After the distance between electronic equipment and the user reduces, if keep the original volume of electronic equipment, then the volume heard of user will increase.Adopt this step, can reduce the volume of described electronic equipment according to the change of distance value, the volume approximate constant that the user is heard.
The principle that reduces to input volume is similar to above-mentioned principle, can make in the voice call process volume approximate constant that the user of the equipment of the other end receives.
In sum, the volume adjusting method that present embodiment provides, by obtaining the change of distance information between electronic equipment and the user, the changing value of adjusting the distance is judged, regulate output and/or the input volume of electronic equipment according to judged result, can regulate the volume of electronic equipment according to the distance between electronic equipment and the user, thereby can make the user hear the sound that volume is relatively constant.
