Hereinafter, various exemplary embodiments according to the present utility model will be described in detail with reference to the accompanying drawings.
Fig. 1 shows a schematic diagram of a vehicle light adjustment system 100 in accordance with one or more embodiments of the application. The vehicle light adjustment system 100 includes an audio acquisition device 110, a multimedia processing device 120, and a light control device 130.
The audio collection device 110 is used to collect and process audio from one or more sources. The audio collection device 110 may be, for example, provided in an in-vehicle entertainment system or may be a separate device from the vehicle that collects, stores, and initially processes audio that occurs or plays within a certain range (e.g., in the vehicle). For example, sound sources of human voice and music video play occurring in a car are collected. Alternatively, the audio capturing apparatus 110 may be directly connected to the sound generating apparatus to obtain audio information, such as a USB device for playing audio, a mobile entertainment device (e.g., a mobile phone), etc., and then obtain audio feature information (such as frequency, tone color, singer of music, etc.) of the audio being played or to be played in these devices, where the audio information may be stored in advance by the audio sources, or the audio data may be directly input to the audio capturing apparatus 110 and preliminarily stored and processed by the audio capturing apparatus 110.
In some examples, the one or more sources from which audio is captured may include, but are not limited to: a voice (e.g., speaker in car, singer), a universal serial bus USB device (e.g., cell phone playing audio, MP 3), a wireless device (e.g., cell phone using bluetooth to transmit audio data, notebook computer, tablet computer), a cloud server (e.g., application platform using cloud storage to store audio such as music), a radio (e.g., radio audio for car radio), or some car entertainment platform. The processing of the audio acquisition device 110 may include, for example, analog-to-digital/digital-to-analog conversion of audio data/information, sample quantization, and the like.
The multimedia processing device 120 is configured to analyze the collected and processed audio to obtain audio feature information, and generate a corresponding light setting control signal according to the audio feature information. The multimedia processing apparatus 120 receives the audio data collected and processed by the audio collection apparatus 110 via a wired connection or a wireless connection (e.g., a bluetooth connection, an in-vehicle lan connection, etc.), and performs audio feature analysis on the audio data. The audio feature analysis may, for example, include analyzing the frequency, timbre, speaker information, emotion tags, pitch, volume, etc. of the audio to analyze emotion color (e.g., hyperthermia, tranquility, rushing, calm, happiness, sadness, etc.), rhythm, style, etc. of the audio. For example, for dynamic music (such as a talk-ing and rock-and-roll) played by a mobile phone to an in-vehicle entertainment system via bluetooth, a rapid frequency change rhythm of the audio can be analyzed, so as to generate corresponding light change reference data. In particular, the emotion information, rhythm information, and the like of the audio obtained by the audio analysis may be referred to generate the corresponding light change control information (light setting control signal).
The light control device 130 controls the setting of the light according to the light setting control signal. The light control device 130 generates a control signal for controlling various attributes of the light based on the aforementioned corresponding light variation reference data generated by the multimedia processing device 120 according to the result of the audio feature analysis, such as controlling the on/off of the light, the light on range (which ranges of the light are on and others are off), the on/off rhythm (the rhythm of turning off and on between the lamps), the nature of the light itself (such as color, brightness, saturation, frequency, etc.).
According to the application, each audio frequency in the vehicle is realized to generate a mutually coordinated and mutually adaptive light change effect with the audio frequency, so that the atmosphere in the vehicle is baked, and the driving interactivity and the pleasure are improved. It is understood that the lights for exhibiting the light effect may typically include an in-vehicle atmosphere light, an in-vehicle illumination light, a display light of a center console display of a driving front row, a display light of a video player in a vehicle, and the like. And the lamp light setting of the lamp can be started and controlled in the wild in a camping mode, so that the amusement experience of camping and the like can be improved.
In some embodiments, any two or three of the audio acquisition device 110, the multimedia processing device 120, and the light control device 130 may be integrated in the same in-vehicle entertainment system to facilitate internal wired connections and volume reduction.
As an example, in some embodiments, analyzing the audio includes analyzing a frequency change of the audio, the generated light setting control signal being capable of causing the light to produce one or more of the following effects: a flicker variation corresponding to a frequency variation of the audio; a light color change corresponding to the frequency change of the audio; a brightness change corresponding to a frequency change of the audio; a saturation change corresponding to a frequency change of the audio; and a lamp turn-on number and range variation corresponding to a frequency variation of the audio (such as a rhythm that generates turn-on/off in a plurality of lamps, for example, an atmosphere lamp and a dome lamp are alternately turned on/off, or a front atmosphere lamp and a rear atmosphere lamp are alternately turned on/off, etc.).
In addition, a plurality of colors of the light corresponding to each other one by one can be set for a plurality of frequency ranges of the audio, for example, a conventional audio frequency range which can be heard by the human ear is divided into a plurality of sub-ranges, and each sub-range corresponds to a color of one light. For example, 4 primary colors may be defined: the audio frequency sub-ranges corresponding to red (R), yellow (Y), blue (B), green (G) and 4 intermediate colors orange (O), purple (P), cyan (C), and yellow-green (H) may be defined as 0 for the saturation and brightness of the color corresponding to the audio frequency at the center of each sub-frequency range. Based on this, corresponding to an equal proportional change in audio frequency, the saturation and brightness may also change proportionally, e.g. an increase in frequency may correspondingly increase the saturation and brightness (or vice versa).
According to one or more of the above embodiments and combinations thereof, the vehicle light adjusting system based on audio analysis of the present application may collect audio data from music being played in a vehicle using its audio collection device, and analyze the audio data using a multimedia processing device to obtain audio feature information. These audio feature information include: frequency variation of the audio (which may be shown, for example, as a frequency effect diagram), tempo of the audio (e.g. number of occurrences of a certain frequency fx within 1 second). Then, the multimedia processing device obtains the color change of the lamplight, the saturation and brightness change in the single color and the flickering times in 1 second of the single color according to the frequency change of the audio, and generates a corresponding lamplight setting control signal. Among them, it is preferable that the saturation and the brightness are changed in proportion to the frequency change within a single color. Finally, the light control device controls the vehicle-mounted light to make corresponding light change according to the light setting control signal.
Besides analyzing the audio to obtain emotion characteristics, the lamplight setting control signal can be directly adjusted according to emotion label information of the audio. Specifically, the emotion tag information of the audio refers to emotion classifications identified for the audio data, for example, a sad music/song may have a sad emotion tag in the audio data, a small program playing on the vehicle-mounted central entertainment platform may have a light, cheerful or other positive emotion tag in the audio data, and a rock music may have an excited emotion tag. Therefore, the light change corresponding to emotion can be generated, for example, the light change corresponding to 'sadness' can be mainly changed in a soft way, the light color with a cool tone is adopted, and the light change effect similar to a dance hall, such as severe and rapid change, can be generated when 'excitation' is carried out.
In other embodiments, light control may be based on human voice occurring within the vehicle. For example, the general emotional atmosphere in the vehicle may be determined according to the frequency of the sounds of the personnel in the vehicle, such as a shortness and a surprise with a large decibel, etc., may prompt the driver to encounter a dangerous factor, at which time a light attribute (e.g., a red flashing atmosphere light of a warning) suitable for exhibiting dangerous alertness may be generated. And a voice recognition module can be additionally arranged in the vehicle light adjusting system, so that the sound text of the person in the vehicle is recognized, and the corresponding light attribute is generated according to the text content. In addition, can also gather the sound that takes place outside the car, for example ambulance, police car's the song to produce the warning atmosphere light that for example red glistens, so as to remind the driver to pay attention to dodging.
According to another aspect of the present application, a vehicle is provided, wherein the vehicle may comprise any one of the vehicle light adjustment systems 100 as described above. The term vehicle in the present application is intended to mean any suitable vehicle having a drive system, such as a fuel-powered vehicle, a hybrid vehicle, an electric vehicle, a plug-in hybrid electric vehicle, and the like.
The above is merely an embodiment of the present application, but the scope of the present application is not limited thereto. Other possible variations or substitutions will occur to those skilled in the art from the teachings disclosed herein and are intended to be within the scope of the present application. The embodiments of the present application and features in the embodiments may also be combined with each other without conflict. The protection scope of the present application is subject to the claims.
