Consult Fig. 1, Fig. 1 is the flow chart of volume adjusting method one execution mode of the present invention.The method comprises:
Step S110: mobile terminal receives the original sound signal grabbing from audio playing device that audio playing device sends.
Particularly, a sound collector can be set at the sound place of sending of audio playing device.The original sound signal that audio playing device sends is collected by sound collector immediately.Sound collector collects after original sound signal, returns to audio playing device.Audio playing device sends to mobile terminal by modes such as bluetooth or the Internets by original sound signal.The original sound signal grabbing from audio playing device that the corresponding reception audio playing device of mobile terminal sends.
Be appreciated that audio playing device is the playback equipment on intelligent appliance, for example, can be arranged on the playback equipment on intelligent television, also can be arranged on the playback equipment on intelligent sound box.
Step S120: mobile terminal, when audio playing device does not have voice output, gathers the noise signal of environment.
Particularly, because not at every moment having sound, broadcasts audio playing device, so, can, when audio playing device does not have voice output, gather the noise signal of environment.For example, when described audio playing device does not have voice output, gather the voice output signal of described audio playing device and the audio input signal of described mobile terminal; The audio input signal of described mobile terminal is deducted to the voice output signal of described audio playing device, thereby obtain the noise signal of environment.
Step S130: the original sound signal that mobile terminal collection audio playing device sends is the attenuates sound signal of mobile terminal institute perception while transferring to mobile terminal.
Particularly, audio playing device is play after original sound signal, and original sound signal is transmitted in air, because original sound signal is lossy in the process of propagating, so original sound signal decays in transmitting procedure, and the distance of transmission is far away, decay larger.Mobile terminal is carried by user conventionally, and now, the position at mobile terminal place is the position at user place.So the signal that mobile terminal collects is the signal of original sound signal after overdamping, i.e. what attenuates sound signal, and mobile terminal collected is the attenuates sound signal of mobile terminal institute perception and voice signal sizableness that user hears.
Step S140: the attenuation of the sound for compensating sound playback equipment that mobile terminal obtains according to original sound signal and attenuates sound calculated signals.
Particularly, original sound signal is deducted to attenuates sound signal, can obtain the attenuation of sound.The attenuation of described sound can be for determining the compensation rate to sound.
Step S150: mobile terminal should regulate the volume of audio playing device according to the attenuation of sound and the noise signal inquiry volume table of comparisons to obtain, and sends to audio playing device.
Particularly, mobile terminal carries out decision-making according to the attenuation of sound and noise signal, to obtain the volume that should regulate audio playing device.Usually, if the attenuation of sound is larger, should must be larger by the volume adjusting of audio playing device, if the attenuation of sound is less, should must be less by the volume adjusting of audio playing device; If noise signal is larger, should must be larger by the volume adjusting of audio playing device, if noise signal is less, should must be less by the volume adjusting of audio playing device.And, can on the impact size of user's uppick volume, both shared weights be set according to the attenuation of sound and noise signal.Usually, the attenuation of sound is larger on the impact of user's uppick volume, so, can its weight be arranged more greatly, and noise signal be less on the impact of user's uppick volume, so, can its weight be arranged littlely.For convenient, realize, can make a volume table of comparisons, the described volume table of comparisons stored sound attenuation, noise signal and with the attenuation of sound, the volume of the corresponding audio playing device of noise signal.After determining the attenuation and noise signal of sound, by the inquiry volume table of comparisons, can obtain the volume of audio playing device.
Be understandable that, step S120 and step S130 are to there is no dividing of precedence between step S140, in other execution mode, also can first perform step S130, perform step again S120 and step S140, or first perform step S130 and step 140, then perform step 120 etc.
In such scheme, mobile terminal receives the original sound signal grabbing from audio playing device that audio playing device sends, attenuates sound signal when gathering again original sound signal that audio playing device sends and transferring to mobile terminal by space, then, according to the attenuation of original sound signal and attenuates sound signal acquisition sound.Mobile terminal also, when audio playing device does not have voice output, gathers the noise signal of environment, and according to the volume of the attenuation of sound and noise signal adjusting audio playing device.Due to the communication between mobile terminal and audio playing device, can adopt the methods such as bluetooth or the Internet, not need to adopt same communication protocol also can realize communication, thereby can adjust neatly the volume that audio playing device is exported.
And, mobile terminal is carried by user conventionally, so, the attenuation that mobile terminal obtains approximates the attenuation of listening to the original sound signal that audio playing device sends for user in its position, and the noise signal that mobile terminal obtains approximates the noise signal of hearing in its position for user.When customer location is moved, mobile terminal autocommand audio playing device regulates volume, improves the flexibility of volume adjusting.
Consult Fig. 2, Fig. 2 is the flow chart of another execution mode of volume adjusting method of the present invention.The method of present embodiment comprises:
Step S210: mobile terminal receives the original sound signal grabbing from audio playing device that audio playing device sends.
Particularly, a sound collector can be set at the sound place of sending of audio playing device.The original sound signal that audio playing device sends is collected by sound collector immediately.Sound collector collects after original sound signal, returns to audio playing device.Audio playing device sends to mobile terminal by modes such as bluetooth or the Internets by original sound signal.The original sound signal grabbing from audio playing device that the corresponding reception audio playing device of mobile terminal sends.
Be appreciated that audio playing device is the playback equipment on intelligent appliance, for example, can be arranged on the playback equipment on intelligent television, can be arranged on the playback equipment on intelligent sound box yet, the present invention does not do concrete restriction.
Step S220: mobile terminal, when audio playing device does not have voice output, gathers the noise signal of environment.
Particularly, refer to Fig. 3, because audio playing device not at every moment has sound, broadcast, for example, as shown in FIG., t1 is between moment t2 constantly, and audio playing device does not have sound to broadcast, so, as shown in Figure 4, can be at moment t1 to the moment of the t3 between t2 and t4 constantly, gather the noise signal of environment twice constantly, and double sampling noise signal is averaging, to obtain the noise signal of environment.
Be understandable that, the number of times that gathers the noise signal of environment can arrange as required, for example, can be 3 times, 4 times or more, and the present invention does not do concrete restriction.
Step S230: the original sound signal that mobile terminal collection audio playing device sends is the attenuates sound signal of mobile terminal institute perception while transferring to mobile terminal.
Particularly, see also Fig. 5 and Fig. 6, audio playing device is play after original sound signal 110, original sound signal 110 is transmitted in air, because original sound signal 110 is lossy in the process of propagating, so, original sound signal 110 decays in transmitting procedure, and the distance of transmission is far away, decay larger.Mobile terminal is carried by user conventionally, and now, the position at mobile terminal place is the position at user place.So, the signal that mobile terminal collects is the signal of original sound signal 110 after overdamping, be attenuates sound signal 120, and the voice signal sizableness heard of the attenuates sound signal 120 for the perception of mobile terminal institute that collects of mobile terminal and user.From the contrast of Fig. 6 and Fig. 5, also can find out, the amplitude of the original sound signal 110 shown in amplitude ratio Fig. 3 of the attenuates sound signal 120 shown in Fig. 4 is little.

Particularly, refer to Fig. 7, original sound signal 110 is deducted to attenuates sound signal 120, can obtain the attenuation of sound.In another embodiment, if original sound signal 110 differs far away with the amplitude of attenuates sound signal 120, also can carry out convergent-divergent to the original sound signal 110 grabbing from audio playing device, and zoom to attenuates sound signal 120 and there is maximum likelihood, thereby obtain convergent-divergent voice signal, then, convergent-divergent voice signal is deducted to attenuates sound signal 120, thereby obtain the attenuation of sound.The attenuation of described sound can be for determining the compensation rate to sound.
Step S250: mobile terminal receives the light intensity of the environment at that audio playing device sends or collection audio playing device place.
Particularly, the light collector that gathers light intensity can be set on audio playing device, for gathering the light intensity of the environment at audio playing device place, then, by bluetooth or Internet protocol, send to mobile terminal.Or, the collector that is related to that gathers light intensity is set on mobile terminal, for gathering the light intensity of the environment at audio playing device place.
Step S260: mobile terminal receives institute's audio playing device sends or the on-site temporal information of collection audio playing device.
Particularly, the temporal information collector of acquisition time information can be set on audio playing device, for gathering the on-site temporal information of audio playing device, then, by bluetooth or Internet protocol, send to mobile terminal.Or setup times information on mobile terminal, for gathering the on-site temporal information of audio playing device.
Step S270: mobile terminal should regulate the volume of audio playing device according to the light intensity of the attenuation of sound, noise signal, environment and the on-site temporal information acquisition of audio playing device, and sends to audio playing device.
Particularly, mobile terminal carries out decision-making according to the light intensity of the attenuation of sound, noise signal, environment and the on-site temporal information of audio playing device, to obtain the volume that should regulate audio playing device.Usually, if the attenuation of sound is larger, should must be larger by the volume adjusting of audio playing device, if the attenuation of sound is less, should must be less by the volume adjusting of audio playing device; If noise signal is larger, should must be larger by the volume adjusting of audio playing device, if noise signal is less, should must be less by the volume adjusting of audio playing device; If the light intensity of environment shows it is daytime, the volume of audio playing device should be tuned up, if the light intensity of environment shows it is night, the volume of audio playing device should be turned down; If the on-site temporal information of audio playing device is shown as the non-time of having a rest, the volume of audio playing device should be tuned up, if the on-site temporal information of audio playing device is shown as the time of having a rest, the volume of audio playing device should be turned down.And, can on the impact size of user's uppick volume, both shared weights be set according to the light intensity of the attenuation of sound, noise signal, environment and the on-site temporal information of audio playing device.Usually, larger on the impact of user's uppick volume, so, can its weight be arranged more greatly, and less on the impact of user's uppick volume, so, can its weight be arranged littlely.For convenient, realize, can make a volume table of comparisons, the described volume table of comparisons stored sound attenuation, noise signal, the light intensity of environment, the on-site temporal information of audio playing device and with the volume of the attenuation of sound, noise signal, the light intensity of environment, the corresponding audio playing device of the on-site temporal information of audio playing device.After determining the light intensity and the on-site temporal information of audio playing device of the attenuation of sound, noise signal, environment, by the inquiry volume table of comparisons, can obtain the volume of audio playing device.
In other execution mode, the light intensity of the attenuation that also can determine according to the impact size on user's uppick volume whether to select a sound, noise signal, environment or the on-site temporal information of audio playing device are as the foundation of the volume of adjusting audio playing device, and the present invention does not do concrete restriction.
Be understandable that, step S220, step S250, step S260 and step S230 between step S240, do not have precedence minute, perform step successively S220 herein and just as one of them embodiment, describe to step S260, but not specifically limit.
In such scheme, mobile terminal receives the original sound signal grabbing from audio playing device that audio playing device sends, attenuates sound signal when gathering again original sound signal that audio playing device sends and transferring to mobile terminal by space, then, according to the attenuation of original sound signal and attenuates sound signal acquisition sound.Mobile terminal also, when audio playing device does not have voice output, gathers the noise signal of environment, and according to the volume of the attenuation of sound and noise signal adjusting audio playing device.Due to the communication between mobile terminal and audio playing device, can adopt the methods such as bluetooth or the Internet, not need to adopt same communication protocol also can realize communication, thereby can adjust neatly the volume that audio playing device is exported.
