Type, concentration of smell of the time, smell that put etc. control the instruction that smell plays.
Wherein, the audio-frequency information of the application scenarios received and preset audio information are carried out by feature by control module 12
Match, is by the audio-frequency information of the collected application scenarios of sound acquisition module 11 and to preset in this feature matching process
Good audio-frequency information carries out vectorized process, establishes corresponding tag file, corresponding by what is set in control module 12
Sound Match Recognition Algorithm judged, in the Sound Match Recognition Algorithm set a specific sound similarity value, will
The sound similarity value compares obtained comparing result and the sound similarity value, as a feature reference value when right
It is compared than result with the sound similarity value, when being greater than or equal to the sound similarity value, that is, is considered as successful match, when small
When the sound similarity value, that is, it is unsuccessful to be considered as matching.Herein, specific Sound Match Recognition Algorithm can be by the skill of profession
Which kind of depending on the concrete condition of art personnel, therefore will not repeat them here with algorithm.
Specifically, by taking film scene as an example: before film starts broadcasting, arranging sound detection device to work normally shape
State, sound detection device are started to work immediately.When film starts to play, sound acquisition module 11 can acquire in film in real time
Audio-frequency information, and by the audio information transmissions in real-time collected film to control module 12, when control module 12 will receive
To film in audio-frequency information matched with the feature of preset audio-frequency information, when control module 12 confirmation receive film
Audio-frequency information be the film preset start play audio-frequency information when, control module 12 will provide smell control instruction,
Such as: the instruction for starting to play smell is transmitted to smell playing device by communication module 13, thus trigger smell playing device also into
Enter working condition.
If when control module 12 is matched to the audio that some plot of the centre of film in film scene needs to play smell
When information, the audio-frequency information for playing smell further according to the plot adjusts the smells play signal such as suitable odor types or concentration,
The smell play signal is sent to the work that smell playing device plays out smell by communication module 13.
If control module 12 is again by the correspondence at the end of the corresponding segment multi-story video that this section of plot plays smell plays
Section multi-story video plays the signal terminated and is sent to smell playing device, and smell playing device stops playing smell, sound collection
Module 11 will continue to acquire the audio-frequency information in film scene, into cycle operation state, when control module 12 is matched to film
When film terminates the audio-frequency information played in scene, which is transmitted to smell by communication module 13 by control module 12
Playing device, triggering smell playing device stop working.
A kind of sound detection device and smell playing device provided by the embodiment of the utility model, pass through real-time detection application

Sound acquisition module 11 will continue to acquire sound acquisition audio-frequency information, until control module 12 confirms that the audio for receiving film is believed
When breath is that the film preset starts the audio-frequency information played, control module 12 will provide smell control instruction, such as: start to broadcast
The instruction of deflation taste is transmitted to smell playing device by communication module 13, and then triggers smell playing device and also enter work shape
State.
When control module 12 is not matched to the audio-frequency information for needing to play the film plot of smell in film scene, control
It is not the signal for needing to play smell in film plot that molding block 12, which will provide, and sound acquisition module 11 will continue to acquire film field
Audio-frequency information in scape needs to play smell until control module 12 is matched to some plot of the centre of film in film scene
When audio-frequency information, the smells such as suitable odor types or concentration are adjusted further according to the audio-frequency information that the plot plays smell and play letter
Number, which is sent to the work that smell playing device plays out smell by communication module 13.
At the end of the corresponding segment multi-story video that this section of plot plays smell plays, control module 12 is again by the corresponding segment feelings
The signal that section video playing terminates is sent to smell playing device, and smell playing device stops playing smell, sound acquisition module
11 will continue to acquire the audio-frequency information in film scene, into cycle operation state, when control module 12 is matched to film scene
When middle film terminates the audio-frequency information played, which is transmitted to smell by communication module 13 and plays dress by control module 12
It sets, triggering smell playing device stops working.
