Please refer to fig. 1, which is a schematic structural diagram of a vehicle-mounted atmosphere lamp rhythm control system disclosed in this embodiment, an atmosphere lamp controller 1 is independent of a central control system of an automobile, that is, the control operations of the atmosphere lamp controller 1 and the central control system are mutually independent, so as to avoid occupying control resources of the central control system, and in this embodiment, the atmosphere lamp controller 1 has a data operation function; after obtaining the control signal through operation, the atmosphere lamp controller 1 provides the atmosphere lamp control signal to the atmosphere lamp driving board 2, so that the vehicle-mounted atmosphere lamp 3 is driven by the atmosphere lamp driving board 2 to emit light regularly; in this embodiment, the vehicle-mounted atmosphere lamp 3 may be implemented by RGB light emitting diodes, which rhythm along with the played music through different frequencies of on and off, different brightness, and/or colors of the lights; the atmosphere lamp driving board 2 and the vehicle-mounted atmosphere lamp 3 can be detachably connected or fixedly connected.
Referring to fig. 2, a schematic flow chart of a vehicle-mounted atmosphere lamp rhythm control method disclosed in this embodiment is used for the atmosphere lamp controller 1, and the vehicle-mounted atmosphere lamp rhythm control method includes: step S100, step S200, step S300, step S400, and step S500, wherein:
step S100, acquiring an original audio signal in a time domain, and performing frequency domain conversion to obtain a frequency domain signal. In this embodiment, the original audio signal represents music currently being played. The acquisition of the original audio signal can be realized by collecting through a microphone, and can also be realized by receiving a signal sent by the mobile terminal. Specifically, the method comprises the following steps:
in one embodiment, referring to fig. 1, in step S100, music currently being played is collected by the microphone 4 to obtain an original audio signal. The music currently played may be music played by the vehicle-mounted sound box, music played by the mobile terminal, singing by the user, or a combination of the above sound sources, that is, the music can be collected by the microphone 4.
In another embodiment, referring to fig. 1, the ambience lamp controller 1 performs data interaction with the mobile terminal 5, and in step S100, receives audio data sent by the mobile terminal to obtain an original audio signal. In this embodiment, the user in the vehicle can play music through the mobile terminal 5, and the mobile terminal 5 directly transmits the currently played music to the ambience lamp controller 1 in a communication manner, specifically, data interaction between the ambience lamp controller 1 and the mobile terminal 5 may be wired or wireless. The mobile terminal 5 may be for example a mobile phone, tablet or music player etc. as long as the mobile terminal is capable of playing music and data interaction with the ambience light controller 1. As an alternative embodiment, the mobile terminal 5 may have the function of installing application software to analyze the data transmitted by the ambience lamp controller 1, e.g. big data analysis.
Step S200, obtaining the frequency, amplitude and lyric information of the music currently playing based on the original audio signal. In a specific embodiment, when the original audio signal is acquired in step S100, the original audio signal may be converted into an audio signal in a digital format, and of course, when a signal sent by the receiving mobile terminal is used, it is digital music itself, and analog-to-digital conversion may not be required. In this embodiment, after the frequency domain signal is obtained by performing frequency domain conversion on the original audio signal, acoustic features of corresponding music, such as frequency, amplitude, and the like, may be identified, and lyric information may also be extracted based on a speech recognition technology. In the embodiment, through extracting the lyric information, the category or style of the music currently playing can be better known, so that a more accurate reference is provided for rhythm control. In this embodiment, the music style may be rock, bruise, classical, etc., and the current music style may be determined comprehensively by acoustic characteristics, lyric information, and the instruments used, etc.
In step S300, a history control signal sequence corresponding to the currently playing music is obtained according to the frequency, amplitude and lyric information of the currently playing music. In this embodiment, the historical control signal sequence is a historical atmosphere lamp control signal generated for the same piece of music, specifically, for the music currently being played, before, the user has played the music, and the atmosphere lamp controller performs rhythm control on the vehicle-mounted atmosphere lamp based on the music, that is, before, the music generates an atmosphere lamp control signal, and the atmosphere lamp control signal collection corresponding to the music is the historical control signal sequence; in a specific implementation, the historical control signal sequence may be updated iteratively over time, i.e. the modified control signal is played later instead of the previous control signal, thereby making the historical control signal sequence match the played music more and more.
In this embodiment, by obtaining the historical control signal sequence corresponding to the currently playing music, it is not necessary to recalculate the control signal each time the music is played, and the amount of computation is reduced.
Step S400, the historical control signal sequence is adjusted according to the frequency, amplitude and lyric information of the music being played currently to obtain a current atmosphere lamp control signal. In this embodiment, after the historical control signal sequence corresponding to the currently playing music is obtained, the current ambience light control signal can be obtained only by performing corresponding adjustment based on the frequency, amplitude and lyric information of the currently playing music on the basis of the historical control signal sequence, specifically, in the process of historically playing music, there may be environmental factors such as noise that may interfere with the music at that time, and therefore, the historical control signal may have factors that do not match the current environment, so the historical control signal sequence can be adjusted by using the frequency, amplitude and lyric information of the currently playing music, thereby obtaining the ambience light control signal that more matches the current environment.
Step S500, outputting a current atmosphere lamp control signal to an atmosphere lamp driving board to enable the atmosphere lamp driving board to drive the vehicle-mounted atmosphere lamp to emit light in a rhythm mode, so that the brightness and the on-off frequency of the vehicle-mounted atmosphere lamp are matched with the rhythm of the currently played music, and the color of the vehicle-mounted atmosphere lamp corresponds to the category of the currently played music. The category of the music can be classic, popular and rock, jazz and the like, and the category can be set according to actual needs. In this embodiment, the vehicle-mounted atmosphere lamp may be an RGB light emitting diode, and under the driving of the atmosphere lamp driving board, the vehicle-mounted atmosphere lamp may generate a color matching with the style of the currently played music festival, for example, a classic corresponding to green, a popular corresponding to rock corresponding to red, a jazz corresponding to blue, and the like, and of course, the corresponding relationship of the colors may be changed according to actual needs; the brightness and the on-off frequency of the vehicle-mounted atmosphere lamp are matched with the music rhythm played currently, namely, the vehicle-mounted atmosphere lamp is turned on and off along with the music beat.
