Example 1
Fig. 1 is a schematic flow chart of a light rhythm method in an embodiment of the present application, where an execution subject of the method may be a terminal device, for example, a light effect driving device, and the embodiment is illustrated by taking the light effect driving device as an example, and as shown in fig. 1, the light rhythm method may include the following steps:
Step S101, obtaining target audio data, processing the target audio data, and determining a decibel value corresponding to the target audio data.
In this embodiment, the light effect driving device may acquire target audio data sent by a PC host, a display, and other devices that may send signals to the light effect driving device, so that the target audio data is correspondingly processed based on the sender, so as to control the corresponding light beads to emit light according to the determined decibel value, thereby implementing audio light rhythm. The display may be a desktop display, a portable electronic competition display, or the like, for example, a Mini Led, an OLED, or the like, and the display may be applied to a home office desk, and the light beads may be eye-protection lamps on the display, or home atmosphere lamps, or the like.
As shown in fig. 2, the PC host may send the digital audio data to the display through signals such as HDML, DP, type-C, so that after the Scaler chip in the AD board of the display processes the digital audio data into the target audio data, the target audio data is sent to the CH340 serial port protocol chip in the light-effect driving device, and the chip sends the target audio data to the CX32L003 chip in the light-effect driving device, so as to drive the light beads to emit light; the PC host can also process the audio data by using the internal PC control software to obtain target audio data, the target audio data is sent to the display through the USB signal, the display sends the target audio data to the CH340 serial port protocol chip in the lamp effect driving device through the USB signal, and the chip sends the target audio data to the CX32L003 chip in the lamp effect driving device so as to drive the lamp beads to emit light. Wherein, the Scaler chip has the audio decoding capability of the digital audio data, thereby realizing Scaler-level lamp effect rhythm; the CX32L003 chip is a high-speed singlechip with a Cortex-M0 kernel and is provided with a high-speed SPI driving IO port, and the chip can drive various lamp beads. It can be understood that, because the lamp effect driving device is connected with more lamps, the lamp effect driving device can be connected with the AD board of the display in an externally hung mode, and can carry out IIC communication with the AD board.
In one embodiment, the step S101 may include: the driving device obtains the format of the target audio data and splits the target audio data into audio data corresponding to left and right channels according to the format.
For example, if the format of the target audio data is the PCM 16-bit audio data format, it is described that the audio data corresponding to the left and right channels in the audio data in one period respectively occupy two bytes, and an alternate storage manner is adopted, that is, the audio data in one period sequentially circulates in sequence as the left channel data of 2 bytes, the right channel data of 2 bytes, the left channel data of 2 bytes, and the like, so that according to the storage period of the audio data, the audio data can be split by using the For circulation means, thereby obtaining the audio data respectively corresponding to the left and right channels.
In an embodiment, the splitting the target audio data into audio data corresponding to the left and right channels may further include: when the display processes the target audio data, a processing chip in the display can split the target audio data so as to obtain audio data corresponding to left and right sound channels respectively, wherein the processing chip can be an AD83586 chip; when the PC host processes the target audio data, the PC host can split the target audio data, so that audio data corresponding to the left and right channels respectively are obtained.
Correspondingly, the corresponding decibel values of the audio data corresponding to the split left and right channels can be calculated according to a preset algorithm. For example, the left channel corresponds to a left decibel value of:
left db value= (absolute value of sum of audio data corresponding to left channel) ×400/(total number of collected audio data/2×2) 16 )
The right decibel value corresponding to the right channel is:
right decibel value = (absolute value of sum of audio data corresponding to right channel) ×400/(total number of collected audio data/2×2) 16 )
Accordingly, when obtaining the db values of the audio data corresponding to the left and right channels, the following step S103 may include: and driving the lamp beads corresponding to the left and right sound channels on the display to emit light simultaneously according to the number of the lamp beads and/or the brightness of the lamp beads. For example, as shown in fig. 3, if the E area and the F area in fig. 3 respectively represent a light band composed of a preset number of light beads, the E area and the F area can respectively correspond to the left channel and the right channel, so that the light rhythms can be realized by respectively controlling the light beads in the light bands corresponding to the E area and the F area.
In one embodiment, the light efficiency driving device may perform fault tolerance processing on the db value, and the step S101 may include: judging the decibel value and a first preset threshold value and a second preset threshold value which are preset to determine whether the decibel value exceeds a range, thereby determining whether the decibel value needs to be corrected according to a judging result, and specifically, if the decibel value is larger than the first preset threshold value, determining the first preset threshold value as the decibel value; and if the decibel value is smaller than a second preset threshold value, determining the second preset threshold value as the decibel value.
In one embodiment, since the audio rhythm is beat, when the beat is too fast, the audio drop sound effect corresponds to the light rhythm, which can lead to the connection of the lamp beads forming the lamp band, and the light rhythm effect corresponding to the audio drop sound is not visible, or the light rhythm effect is poor, the audio data of the preset frame in the range of 30 frames to 40 frames can be selected for processing, so that the sound effect is not too fast or too slow, and the visual effect is improved.
Step S102, determining the number of the lamp beads and/or the brightness of the lamp beads corresponding to the decibel values according to a preset mapping relation.
In this embodiment, the light effect driving device establishes a mapping relationship between the db value of the audio frequency and the light beads in advance, so as to determine the number of light beads emitted and the brightness of the light beads emitted according to the mapping relationship, thereby realizing light rhythm. It is understood that the brightness of the light emitted by different beads at the same time as determined by the db value may be different.
In one embodiment, the mapping relationship between the lamp beads and the db values is constructed before step S102, which may specifically include: the linear mapping or linear mapping relation of the segments is established according to the range value of the decibel value and the number of the lamp beads, and the linear mapping or linear mapping relation of the segments can also be established according to the range value of the decibel value and the range value of the brightness of the lamp beads, so that the aim of controlling the number of the lamp beads and the brightness to change along with the audio decibel value is fulfilled.
For example, if the range value of the set decibel value is 0-100, and the number of actually driven lamp beads is 100, a linear mapping relationship of 1:1 can be established; if the number of the actually driven lamp beads is 10, a linear mapping relationship of 10:1 can be established. In addition, the linear mapping relation of the branching section can be established according to the requirement of the user, for example, if the range value of the set decibel value is 0-100 and the number of the actually driven lamp beads is 10, the range value of the decibel value is controlled to be 0-20 to 1, the range value of the decibel value is controlled to be 20-80 to 6, and the range value of the decibel value is controlled to be 80-100 to 3, and the linear relation is respectively established.
Step S103, driving the corresponding lamp beads on the display to emit light according to the number of the lamp beads and/or the brightness of the lamp beads.
In this embodiment, the light effect driving device may drive the light beads on the display according to the determined number of the light beads and/or the determined brightness of the light beads, for example, simultaneously control the light beads corresponding to the corresponding number of the light bands corresponding to the E area and the F area in fig. 3 to emit light, and control the brightness of the light beads currently emitted.
In one embodiment, the light rhythms can be performed according to the picture, which specifically includes: the lamp effect driving device obtains color information of at least one target area on the display picture, determines the lamp bead color of at least one corresponding lamp bead according to the color information of the at least one target area, and drives the corresponding lamp bead on the display to emit light according to the lamp bead color of the at least one lamp bead. The target area may be an area divided on the display screen, and the color of the lamp bead is a color exhibited when the lamp bead emits light.
As shown in fig. 2, the PC host may send digital frame data of the display frame to the display through signals such as HDML, DP, type-C, so that after the Scaler chip in the AD board of the display processes the display frame to obtain color information of at least one target area on the display frame, the color information is sent to the CH340 serial port protocol chip in the light-effect driving device, and the color information is sent to the CX32L003 chip in the light-effect driving device, so as to drive the light beads to emit light; the PC host can also process the display picture by using the PC control software in the PC host to obtain the color information of at least one target area, then the color information is sent to the display through USB signals, then the display sends the color information to a CH340 serial port protocol chip in the light effect driving device through USB signals, the chip sends the color information to a CX32L003 chip in the light effect driving device so as to drive the lamp beads to emit light, and as shown in fig. 3, the lamp beads corresponding to the A area, the B area, the C area, the D area, the E area and the F area in the back of the display in fig. 3 can be controlled according to the color information to emit light with corresponding colors. Wherein, the Scaler chip has the large-area tone analysis capability of the picture, thereby realizing Scaler-level lamp effect rhythm; the beads in the regions a, B, C, D of fig. 3 may be spot lamp beads.
For example, if the lamp bead on the display is the MCU lamp bead of the built-IN chip, it includes four interfaces, VCC/IO, GND/IO, IN/IO, OUT/IO, VCC and GND are power supply pins, IN is a signal input interface, OUT is a signal output interface, if it wants to drive the lamp bead to lighten, it is only necessary to send RGB three-color coordinate values by using one input interface, one lamp bead may correspond to 24BIT data, and the 24BIT data may include coordinate values corresponding to red, green and blue three colors, that is, each 8BIT data corresponds to one color, and the data may be sent according to the GRB order, with a range of 0-255.
If the current lamp beads are connected in parallel, the command ports corresponding to the lamp beads can be connected in series, namely, the output of the previous lamp bead is connected with the input of the next lamp bead, so that when the lamp effect driving device sends a command corresponding to the lamp bead driving to emit light, command data corresponding to the lamp beads are sent together, namely, a command is generated, when the current lamp bead receives 24BIT data in the command, the received 24BIT data are intercepted, the rest command data are sent to the next lamp bead connected with the current lamp bead, and all lamps are driven to emit light, for example, 100 lamp beads are required to be driven currently, and the 100 lamp beads are connected in parallel, so that 100 x 24 bit=2400 BIT data are required.
It can be understood that the driving device can drive the lamp beads to emit light together according to the obtained lamp bead number, lamp bead brightness and lamp bead color, so that the light is enabled to move in real time according to pictures and audio, the immersion sense is better due to the interaction of the audio and video of scenes such as games, films and the like and the light, and the hearing-impaired people can be prompted to feel the atmosphere of the scenes through the light movement of the scenes when facing the hearing-impaired people. In addition, electronic contest elements can be added to the display, and real-time rhythm can be realized.
According to the embodiment of the application, the target audio data are obtained and processed, so that the decibel value corresponding to the target audio data is determined, the number of the lamp beads and/or the brightness of the lamp beads corresponding to the decibel value are determined according to the preset mapping relation, and finally the lamp beads corresponding to the display are driven to emit light according to the number of the lamp beads and/or the brightness of the lamp beads, so that the number of the lamp beads which emit light and/or the brightness of the lamp light which emit light are controlled by the decibel value corresponding to the audio data to correspondingly change, and the light effect displayed on the display is caused to meet the specific scene requirement.
Example two
Fig. 4 is a schematic flow chart of a light rhythm method in an embodiment of the present application, where an execution body of the method may be a terminal device, for example, a PC host, and the embodiment uses the PC host as an example for explanation, and as shown in fig. 4, the light rhythm method may include the following steps:
step S401, an audio rhythm instruction is acquired, and a target audio endpoint is determined from a preset audio endpoint table according to the audio rhythm instruction.
In this embodiment, under some electronic contest scenes, the PC host may be connected to obtain multimedia information, where the multimedia information includes audio information and video information, and when the PC host obtains an audio rhythm instruction, it is indicated that audio rhythm is required currently, and then the PC host needs to determine a target audio endpoint from a preset audio endpoint table so as to obtain audio data in the target audio endpoint, and by quickly determining the target audio endpoint according to the preset audio endpoint table when there is a need, the rapid capturing of audio data is achieved, and further basic data is provided for implementing follow-up lamplight rhythm based on audio. Wherein, the audio endpoint is a device capable of playing audio, namely a device with an audio output channel, including but not limited to a display audio device, a Bluetooth headset, an inserted headset, a PC speaker, etc.; the target audio endpoint is an audio endpoint of the current playing audio of the PC host.
Specifically, the PC host may determine, through the COM component API function in the Window system, an audio endpoint that is currently playing, that is, the target audio endpoint. If two or more audio endpoints exist in the current playing audio endpoint, selecting an audio endpoint needing to perform light rhythm from the current playing audio endpoint according to preset requirement information, and determining the selected audio endpoint as a target audio endpoint. The above requirement information includes audio endpoint priority order, preset number of audio endpoint combinations, etc., and it can be understood that if the audio light rhythms are based on overall audio, the effect will be better, so that mixed audio can be generated according to the preset number of audio endpoint combinations, and if the current playing of music is performed, the mixed audio data can be obtained to perform the audio light rhythms at the same time of playing the game.
In one embodiment, the PC host detects audio endpoints in advance, thereby generating an audio endpoint table based on the detected audio endpoints. Specifically, the output audio data can be detected by a COM component API interface program in the Window system, and each audio endpoint is enumerated, so that an audio endpoint table is generated according to each enumerated audio endpoint.
In one embodiment, the step S402 may include: the target endpoint can be copied to the client audio function while the target endpoint is activated through the Active function of Window, the target endpoint is initialized, the initialized endpoint is used for establishing an audio channel with a mapping relation, the initialized endpoint is equivalent to a storage control for storing audio data, and therefore the audio data in the target endpoint are copied, the full mapping relation is achieved through copying the audio data to the client audio function, the original audio file is not required to be processed, and therefore data analysis and algorithm processing are carried out on the basis that the original video file is not affected.
Step S402, converting the audio data in the target audio endpoint into a preset format to obtain target audio data.
In this embodiment, since different audio formats, bit depths, and channel numbers have differences, for example, there is 8 bits/16 bits/24 bits of audio data, the format of the audio data may be converted by the PC control software installed in the PC host, so that the subsequent processing may be facilitated by unifying the formats, for example, the PC host may unify the acquired audio data into a 16-bit PCM binaural format, so as to implement binaural L/R audio rhythms; because the audio playing frequency of the computer is basically 44KHz, and some audio data do not meet the sampling rate, the audio data can be regulated so that the audio data meet the sampling rate.
In one embodiment, a sharing mode may also be set for the audio data of the target endpoint, and a service corresponding to the sharing mode is started, where the service is started in the sense that the audio data with the format converted may be called by other tasks for processing. It can be understood that the functional modules in the Window system can be set in a sharing mode or an exclusive mode, and the difference between the two modes is whether the two modes can be called by other tasks, for example, applications such as QQ, weChat, tencel meeting, and beauty camera can all call the camera function of the computer, so that the two modes need to be set in the sharing mode so that each application can call; if the exclusive mode is set, after the QQ is turned on, the threaded task occupies the camera function, so that applications such as a messenger conference, a WeChat and a beauty camera cannot call the service. Accordingly, although the audio data of the target audio endpoint is already arranged, the target audio endpoint also belongs to one type of audio, so that the target audio endpoint also needs to be set into a sharing mode, and other tasks can call the processing.
Step S403, the target audio data is sent to a light effect driving device, so that the light effect driving device drives the corresponding light beads on the display to emit light according to the target audio data.
In this embodiment, the PC host sends the processed audio data, that is, the target audio data, to the light effect driving device, so as to implement audio light rhythm, and the light effect corresponding to the audio data obtained by processing the PC host is finer. The method of the step executed by the light effect driving device to drive the corresponding light beads on the display to emit light refers to the first embodiment.
As shown in fig. 2, the PC host sends the target audio data to the display through a USB signal, and then the display sends the target audio data to the CH340 serial port protocol chip in the light-effect driving device through a USB signal, and the chip sends the target audio data to the CX32L003 chip in the light-effect driving device, so as to drive the light beads to emit light.
In one embodiment, the light rhythms can be performed according to the picture, which specifically includes: the PC host acquires a picture rhythm instruction, determines a display picture according to the picture rhythm instruction, acquires lamp bead arrangement information, wherein the lamp bead arrangement information is the arrangement position of lamp beads on a display, divides the display picture into at least one target area according to the lamp bead arrangement information, and as shown in fig. 3, the target areas are an area A, an area B, an area C, an area D, an area E and an area F which are respectively arranged on the back of the display in fig. 3, and determines color information of at least one pixel point in the target area, so that the corresponding relation between the pixel point and the lamp beads in the target area can be set; and transmitting the color information of at least one pixel point in the target area to the light effect driving device, so that the light effect driving device drives the light beads corresponding to the pixel point on the display to emit light according to the color information of the at least one pixel point.
In this embodiment, the color information of at least one pixel in the target area is obtained by processing the display screen with PC control software installed in the PC host, and the PC host sends the color information of at least one pixel in the target area to the light effect driving device to implement video light rhythm, so that the light follows the PC screen to implement fixed point and regional color rhythm, and the color information of at least one pixel in the target area obtained by processing the PC host can promote the number of comparison points of the display screen and the light beads to be relatively large.
It can be understood that, in order to enhance the light rhythm effect, a pixel point may be set to correspond to a light bead corresponding to the pixel point, that is, what color the pixel point is, and what color the light bead corresponding to the pixel point is, so that the light bead emits light in a direction and color synchronous with the display screen is maintained, for example, the color at four corners of the display screen is red, and then the light effect colors of the area a, the area B, the area C and the area D in fig. 3 are also red.
As shown in fig. 2, the PC host sends color information of at least one pixel in the target area to the display through a USB signal, and then the display sends the color information of the at least one pixel in the target area to the CH340 serial port protocol chip in the light-effect driving device through the USB signal, and the chip sends the color information of the at least one pixel in the target area to the CX32L003 chip in the light-effect driving device, so as to drive the light beads to emit light.
In one embodiment, the PC host may determine color information of at least one pixel in the target area by acquiring the pixel in the target area for reading. Specifically, the extraction of the fixed pixel point is performed on the target area, for example, the data information of the top left corner of the screen is acquired, and the color information of the coordinates (0, 0) can be acquired by using the screen color-taking tool getcolor (0, 0).
In one embodiment, before dividing the display screen into at least one target area according to the bead arrangement information, the method may further include: the PC host acquires desktop information; determining a content display area on a preset virtual screen according to the desktop information, wherein the content display area is consistent with the display area on the display in size; and mapping the display picture to the content display area.
Specifically, the display information of the display is determined by obtaining the handle HDC of the entity display, and then the desktop information of the display is determined by the Get SystemMetrics function in the API, for example, the desktop size in the desktop information is 1920 x 1080pix (1080P), then a bitmap object with the same size as the desktop is created, and a bitmap area with the size of the desktop is created, where the bitmap area is the content display area, and the bitmap object is a variable used for storing the picture address in the bitmap format, and the bitmap area is where the bitmap picture is displayed.
In one embodiment, the virtual screen is created before the content display area is determined on the preset virtual screen, which specifically may include: and creating a virtual screen according to the display information through a CreatCompatible DC function in a window system API, wherein the returned handle is hCompDC. It can be understood that if the image capturing process is directly performed on the PC-side physical display, the problem of screen jamming or continuous shake of the mouse may be caused. Therefore, in this embodiment, the display frame can be intercepted in real time, and the display frame can be converted into the picture in the bmp format to be displayed on the created virtual screen, so that the real-time sharing of the frame of the entity display on the virtual screen is realized, and then the image acquisition is performed on the frame on the virtual screen, so that the problem that the frame of the entity display is abnormal can be avoided.
In one embodiment, the PC control software may be further used to perform personalized settings, set a preset mode, and match the rhythm settings corresponding to the preset mode, where the rhythm settings include: respiratory rate, rhythm color, etc.
According to the embodiment of the application, the audio rhythm instruction is acquired, the target audio endpoint is determined from the preset audio endpoint table according to the audio rhythm instruction, then the audio data in the target audio endpoint are converted into the preset format to obtain the target audio data, and finally the target audio data are sent to the lamp effect driving device, so that the lamp effect driving device drives the corresponding lamp beads on the display to emit light according to the target audio data, and accordingly the number of the lamp beads and/or the brightness of the lamp light are controlled according to the decibel value corresponding to the audio data, so that the lamp effect displayed on the display meets the specific scene requirement.

In one embodiment, before step S502, the digital audio data may be split into two, one way is executed to step S502, and the other way is changed into analog signals by processing the digital audio data through the AD83586 chip, so as to realize the splitting of the display audio, and meet the requirements of three audio sources of earphone, speaker and audio rhythm. It can be understood that the audio output of the display can be output through the AudioOut earphone hole, and can also be output through a loudspeaker connected with a power amplifier, if the digital audio data acquired by the display is directly processed, the situation that the interface does not meet the requirement may exist at present, so that the digital audio data needs to be split.
Step S503, the analog audio data is sent to a light effect driving device, so that the light effect driving device converts the analog audio data into target audio data, and the corresponding light beads on the display are driven to emit light according to the target audio data.
In this embodiment, the display implements audio light rhythms by sending analog audio data to the light effect driving device. The light effect driving device can convert the analog audio data into 12-bit digital audio data, namely the target audio data, and because the ADC of the CX32L003 chip is 12-bit accurate, the light effect driving device can prompt the sound source and the chip processing content to be matched, and realizes the audio light rhythm based on the scaler level of the display.

In one embodiment, based on a preset resolution, the display may be partitioned according to preset user requirements, wherein the user may select a corresponding partition effect on a partition option on an OSD menu of the display according to personal requirements.
