Embodiment one
Fig. 1 is a kind of flow chart for lamp effect switching method that the embodiment of the present invention one provides, and the present embodiment can be applied to lamp
The case where tool carries out lamp effect switching with environmental audio, such as household electrical appliances lamps and lanterns carry out the switching of lamp effect or KTV rendering lamp carries out lamp effect and cuts
The scene changed, this method can imitate switching circuit by lamp and realize, the software and/or hardware in switching circuit can be specifically imitated by lamp
To implement.
Referring to Fig. 1, lamp effect switching method includes the following steps:
S110, acquisition environmental audio, judge whether environmental audio is music VF；
Wherein, the lamps and lanterns for carrying out lamp effect switching can be illuminator, or the instruction being set on electronic product
Lamp, wherein electronic product for example can be speaker, refrigerator, air-conditioning, washing machine and television set etc..Wherein, lamp effect switching is carried out
Lamps and lanterns acquisition instructions can acquire environmental audio based on the received, and acquisition instructions can be touched by pressing the physical button of lamps and lanterns
Hair, can also by press with lamps and lanterns pairing other terminals physical button or virtual key trigger, can also with lamps and lanterns
The triggering when voice and default voice of other terminals acquisition of pairing match, can also adopt with other terminals that lamps and lanterns match
The triggering when gesture of collection and default gesture match, is not specifically limited herein.
Optionally, judge whether environmental audio is music VF, comprising:
The temporal signatures for obtaining environmental audio, judge whether environmental audio is music VF according to temporal signatures；And/or
Environmental audio is converted into frequency-region signal, and obtains the frequency domain character of frequency-region signal, judges that environmental audio is according to frequency domain character
No is music VF.
Wherein, environmental audio is the audio data acquired in chronological order, therefore the environmental audio acquired is time domain letter
Number.Wherein, the temporal signatures of environmental audio, it can be understood as the feature of the environmental audio data of acquisition, such as can be along when
Between axis direction environmental audio feature, be also possible to the environmental audio feature along audio amplitude direction.Wherein, according to along time shaft
The environmental audio feature in direction judges whether environmental audio is music VF, can be and judges that the environmental audio of time-axis direction is
It is no continuous, if continuous it may be considered that environmental audio is music VF.Wherein, special according to the environmental audio along audio amplitude direction
Sign judges whether environmental audio is music VF, can be and judges whether the environmental audio in audio amplitude direction is greater than default width
Value, if more than default amplitude it may be considered that environmental audio is music VF.
Wherein it is possible to convert frequency-region signal for environmental audio using time-frequency conversion method, and obtain the frequency of frequency-region signal
Characteristic of field.Wherein, frequency domain character for example can be the frequency that frequency-region signal includes.Wherein, judge that environmental audio is according to frequency
No is music VF, is matched with specific frequency it may be considered that environmental audio is sound if can be the frequency that frequency-region signal includes
Musical sound frequency.
Further, the temporal signatures for obtaining environmental audio judge whether environmental audio is note according to temporal signatures
Frequently, comprising: obtain the continuity Characteristics of environmental audio within a preset period of time；If continuity Characteristics be it is continuous, judge environment
Audio is music VF.
Wherein, environmental audio can be music VF, can also be other audios, for example, footsteps, door slam or say
Words sound etc.；Wherein, since the melody for including in music VF is more continuous, and the sound such as speak or close the door are more discontinuous,
Therefore music VF can be judged whether it is by the continuity of environmental audio.Wherein, environmental audio, which can be, in real time acquires,
The audio section that at least one preset time period can be intercepted after environmental audio is collected, if continuous sound in each audio section of interception
Frequency range proportion is greater than preset ratio, then may determine that environmental audio is music VF.Wherein, preset time period for example can be with
It is 4s or 10s, the quantity for intercepting the audio section of preset time period for example can be 5 sections, 7 sections or 8 sections, and preset ratio for example can be with
60% or 90%, and preset time period, interception audio section quantity and preset ratio all can according to actual needs into
Row is adjusted.
Further, environmental audio is converted into frequency-region signal, and obtains the frequency domain character of frequency-region signal, according to frequency domain spy
Sign judges whether environmental audio is music VF, comprising: environmental audio is converted to frequency-region signal according to Fourier transformation, and is obtained
Take the characteristic frequency of frequency-region signal；Characteristic frequency is matched with default scale frequency meter, environment is judged if successful match
Audio is music VF.
It wherein, include more to advise in the frequency-region signal of music VF due to being made of in music VF each scale
The scale frequency of rule, and speak or door slam in scale frequency it is more irregular, therefore the corresponding frequency domain of environmental audio can be passed through
The frequecy characteristic of signal judges whether environmental audio is music VF.It wherein, can be by ambient sound according to Fourier transform formula
Frequency is converted to frequency-region signal, and can choose and be distributed more frequency in frequency-region signal as characteristic frequency.It further, can will be special
Sign frequency is matched with default scale frequency meter, if being matched to from default scale frequency meter identical with characteristic frequency each pre-
If scale frequency, and matched each default scale frequency meets scheduled rule change, such as meets common and rotation scale and become
Change regular " 15634125 ", " 4536251 " or " 1563451 " etc., it may be considered that environmental audio is music VF.In addition, if
It is not matched to default scale frequency identical with characteristic frequency or matched default scale frequency from default scale frequency meter
Scheduled rule change is not met, it may be considered that environmental audio is not music VF.
S120, switch if so, carrying out lamp effect according to environmental audio.
Wherein, when judging environmental audio for music VF, lamp effect switching can be carried out according to environmental audio.Wherein, it acquires
Environmental audio not only may include user speech but also may include terminal outer playback frequency, thus extend lamp effect switching audio come
Source.In addition, only environmental audio be music VF when just carry out lamp effect switch, when ambient sound is not music VF without
Lamp effect switching enriches lamp effect switching method, improves user-interaction experience so as to build better audiovisual atmosphere.
