Embodiment
In order to make the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail, and obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
In order to solve the television sound volume existed in prior art increase suddenly time, under the prerequisite of special key not increasing the control terminals such as remote controller, the technical problem fast controlling volume cannot be realized, a kind of method that the embodiment of the present invention provides television sound volume to regulate and device, under the prerequisite of special key not increasing the control terminals such as remote controller, detect the electrical power value from the voice signal of signal source by power detector; When receiving volume adjusting control command, judging whether volume adjusting control command is used to indicate and volume is reduced, if so, then judging whether the electrical power value detected is greater than the average electrical power value of setting; If the electrical power value detected is greater than average electrical power value, then electrical power value is adjusted, the electrical power value after adjusting is made to be average electrical power value, and then realize the volume control operations more quickness and high efficiency of user, such as when user selects " volume-", just can obtain the volume oneself wanted by a key operation, thus promote Consumer's Experience.Average power content in the embodiment of the present invention can control custom according to the volume of different user group and carry out dynamic conditioning, and then meets the volume adjusting demand of different user.
A kind of television volume regulating method provided the embodiment of the present invention below and device are described in detail.
A kind of television volume regulating method that the embodiment of the present invention as shown in Figure 1 provides, comprising:
Step 101, volume of reception regulating control command;
Step 102, detects the electrical power value of the voice signal from signal source;
Step 103, judges whether volume adjusting control command is used to indicate and volume is reduced, if so, then judge whether the electrical power value detected is greater than the average electrical power value of setting;
Step 104, if the electrical power value detected is greater than average electrical power value, then adjusts electrical power value, makes the electrical power value after adjusting be average electrical power value.
In said method flow process, volume of reception regulating control command can be user selects by control terminals such as the remote controllers of TV the user instruction that triggers during volume adjusting, and such as, user clicks " volume-" button of television set.Also can be the voice regulating command etc. that user is issued by speech recognition system.
In the step 102 of said method flow process, detect the electrical power value of the voice signal from signal source, include but not limited to, detect the electrical power value of voice signal after amplifying and processing from signal source.
Average electrical power value for setting in said method process step 103 can be arrange a default value before TV dispatches from the factory, this default value is applicable to most of user, this average electrical power value can control custom according to the volume of different user and dynamically update, preferably, by with under type step of updating 103 setting average electrical power value:
Obtain the electrical power value of the voice signal from signal source detected in very first time length; Calculate the mean value of the electrical power value of the voice signal from signal source detected in very first time length; If the mean value of the electrical power value of voice signal is not equal to average electrical power value, then average electrical power value is updated to the mean value of calculating.
Such as, definition very first time length is 60 seconds, if user does not carry out volume operation within the time of 60 seconds, obtains the electrical power value of the voice signal from signal source detected in 60 seconds; The mean value calculating the electrical power value detected in 60 seconds is 2W; If the average electrical power value stored before these 60 seconds is 1.5W, then the average electrical power value of storage is updated to 2W, that is, as long as TV is always at open state, just can upgrades an average electrical power value every 60 seconds.The needs meeting different user or varying environment scene in real time can be ensured like this.
Optionally, the embodiment of the present invention can also revise according to the frequency information of the voice signal of signal source the average electrical power value determined in above-described embodiment, includes but not limited to under type:
Detect the frequency from the voice signal of signal source; Obtain the frequency of the voice signal from signal source detected in very first time length; Add up the frequency distribution of the voice signal from signal source detected in very first time length; Described average electrical power value after upgrading according to described frequency distribution and the correction of voice signal equal loudness contour, the correction value of average electrical power value can set suitable algorithm based on the equal loudness contour of voice signal and obtain.This kind of mode combines sound frequency, can adapt to being accustomed to ear of user better.
The equal loudness contour ISO226 of the voice signal of up-to-date test in 2003 as shown in Figure 2, abscissa is the frequency of sound, and ordinate is the acoustic pressure of sound.As can be seen from Figure 2, keep acoustic pressure constant, under different frequency, the loudness that people's ear subjectivity is heard is different, in Fig. 2, each curve represents the equal loudness contour of a loudness value, the loudness value of any point namely on same curve is identical, and the sound that the curve people ear that loudness value is high is heard is louder.The unit definition of the loudness of sound is phon, and i.e. " side ", loudness value is larger, and representative voice is louder.Figure comprises the equal loudness contour of threshold (threshold sound intensity value 0 side), 20 sides, 40 sides, 60 sides, 80 sides, 100 sides (dotted portion is discreet value).
In order to make volume adjusting more accurate, the embodiment of the present invention is also connected electrically in the frequency values of the power detector between process amplifier and loud speaker to voice signal by inside television and detects, based on the frequency distribution of voice signal, using the equal loudness contour of voice signal as with reference to factor, the average electrical power value after upgrading is revised.If the average electrical power value stored described in controller is sometime 2.5W, after this moment, the mean value of the electrical power value of the voice signal from signal source that 60 seconds internal power detectors detect is 2W, if do not consider other factors, then average electrical power value should be updated to 2W.If also detected that the high-frequency band of 3-4kHz in the frequency distribution of voice signal was in the majority in these 60 seconds, according to the equal loudness contour of voice signal, the loudness value of the high-frequency band of 3-4kHz is comparatively larger than standard loudness value, that is, relative to most of user, under less electrical power, just can obtain larger loudness, therefore, if consider the frequency of voice signal, then average electrical power value may should be updated to 2.2W, show that the loudness of the voice signal in these 60 seconds is larger.These are after 60 seconds, if power detector monitors electrical power value be greater than this average electrical power value, then electrical power value is adjusted to average electrical power value by control treatment amplifier.
Step 103 for said method flow process can realize in the following ways: judge whether volume adjusting control command is used to indicate and volume reduced, if so, then judge receiving the electrical power value detected in the second time span after volume adjusting instruction and whether be greater than the average electrical power value of setting.
If be greater than described average electrical power value receiving the electrical power value detected in the second time span after volume adjusting instruction, then described electrical power value is adjusted, make the electrical power value after adjusting be described average electrical power value.
After electrical power value is adjusted, also comprise:
According to the adjusting range between the electrical power value before the electrical power value after adjustment and adjustment, and output sound value when receiving volume adjusting control command, determine target output sound value;
Amplitude of variation between output sound value according to target output sound value and when receiving volume adjusting control command, determines target display volume value, and controls display-object display volume value.
Such as, second time span is set to 0.5 second, user watches certain TV play, the volume value 30 of whole set of television, the average electrical power 0.2W of now inside television storage, now break for commercialsy, audio input signal increases suddenly, and after advertisement play for 1 second, user's perceived sounds is too large, and find remote controller, click " volume-" key.After inside television receives the volume reduction instruction of user, detect that the average electrical power of the voice signal of 0.5 second inserting advertisement increases to 2W instantaneously, the average electrical power of the voice signal therefore broken for commercialsy is greater than electrical power mean values 0.2W, by controlling the electrical power of the voice signal of signal source to decay to 0.2W, when the electrical power of the voice signal of signal source decays to 0.2W by 2W, the volume that loud speaker exports is reduced to desired value, in order to the volume value after the decay that user can be made to see display shows, the volume value as calculated display shown needs to drop to 15, therefore can control display display volume value suitable is at present 15.
In above-described embodiment, step 102 also can comprise: detect from signal source voice signal without amplify process before electrical power value, and based on the signal source detected voice signal without amplify process before electrical power value, perform said method flow process, television sound volume is regulated, identical technique effect can be reached.
In above-described embodiment, be used to indicate volume down hour when receiving volume adjusting control command, the electrical power value of the voice signal detected when receiving volume adjusting control command and the average electrical power value of setting are compared, if the electrical power value detected is greater than average electrical power value, then electrical power value is adjusted, the electrical power value after adjusting is made to be average electrical power value, because average electrical power value controls custom according to the volume of user to carry out arranging or dynamic conditioning, such as in setting-up time section, volume is set to certain output sound value according to user, detect in this setting-up time the electrical power of the voice signal of the signal source of audio frequency and video of televising, the mean value of the electrical power of voice signal in this setting-up time is defined as average electrical power value.Therefore, by the logic control of said method flow process achieve user one key operation just can intelligence volume is reduced to user expect volume value, make the volume control operations more quickness and high efficiency of user, thus promote Consumer's Experience.
Average power content in the embodiment of the present invention can control custom according to the volume of different user group and carry out dynamic conditioning, and then also can meet the volume adjusting demand of different user.

Step S4: adjust electrical power value, makes the electrical power value after adjusting be average electrical power value;
Step S5: carry out volume according to the volume adjusting step-length preset and increase adjustment, make output sound value increase a volume unit; Such as, if user is pressed out " volume+" by button, then routinely the mode of " volume+" is carried out volume and is increased operation.
Step S6: carry out the little adjustment of volume down according to the volume adjusting step-length preset, make output sound value reduce a volume unit.Such as, user is watching a ball game, and complete machine volume value is 35, the electrical power 0.2W of television sound signal.But to night, have a rest to not affect household, user presses " volume-" key.Now, can judge that the mean value of the electrical power of voice signal is not more than average electrical power value, conventionally carry out volume and reduce operation.User presses continuously " volume-" key, until volume value drops to 5, user feels to reach requirement, stops key, and is now about 0.0002W compared with the electrical power value of the voice signal of small volume.Through after a period of time, such as 60 seconds, the average electrical power value of system storage can be updated to 0.0002W).After this, then the situation that the sound having advertisement or zapping to cause increases suddenly, user still can realize " key control ".
