Detailed Description

The core of the invention is to provide a method for controlling a plurality of light sources based on music and related components thereof, which can control a plurality of bulbs, realize wireless connection between a control terminal and the plurality of bulbs, do not need additional wires for connection and improve usability.

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 and fig. 2, fig. 1 is a flowchart of a method for controlling a plurality of light sources based on music according to the present application, and fig. 2 is a schematic structural diagram of an apparatus for controlling a plurality of light sources based on music according to the present application, which is applied to a processor in a control terminal 1, where the processor is connected to N bulbs 2 through bluetooth Mesh, N is a positive integer, and the method for controlling a plurality of light sources based on music includes:

s1: generating a corresponding light control instruction according to the music signal received by the processor;

in order to change the light effect of the bulb 2 along with the music played by the user, the music played by the user needs to be collected firstly, and a light control instruction which is in accordance with the style and atmosphere of the music is generated according to the music collected by the processor, for example, when the user plays the soothing music, the processor can generate a light control instruction which enables the light color of the bulb 2 to be adjusted to be warm tone light, and the light intensity is adjusted positively and dependently according to the decibel of the music, so that the light intensity and the light color of the bulb 2 are in accordance with the atmosphere of the soothing music, and the feeling of the user on the soothing experience is enhanced. In consideration of the fact that in practical application, the control terminal 1 may be a mobile phone of a user, and the mobile phone can not only receive music signals played by other music playing devices, but also play music, so when the control terminal 1 is the control terminal 1 capable of playing music, the music signals received by the processor may be music played by itself, or music played by other music playing devices, and the setting may be specifically performed according to the actual requirements of the user.

S2: and the light control instruction is respectively sent to the N bulbs 2 through the Bluetooth Mesh.

The bluetooth mesh is a function for communication between devices, and when a plurality of devices supporting the bluetooth mesh function have a connection relationship, it is equivalent to that the connection relationship exists between every two of the devices, for example, the device a is connected with the device B, the device B is connected with the device C, and the device C is connected with the device D. Based on this, in order to realize that the control terminal 1 controls the plurality of bulbs 2 simultaneously, the bulbs 2 supporting the bluetooth mesh function and the control terminal 1 supporting the bluetooth mesh function may be adopted, the bulbs 2 are connected with each other through the bluetooth mesh, so that a bluetooth mesh connection relationship exists between any one bulb 2 and any other bulb 2, the control terminal 1 is connected with any one bulb 2 through the bluetooth mesh, the purpose that the control terminal 1 is connected with all bulbs 2 is realized, at this time, the control terminal 1 may send the light control instruction to all bulbs 2, and thus the purpose that the control terminal 1 controls the plurality of bulbs 2 simultaneously is realized.

In addition, when the bulbs 2 are connected with each other through bluetooth mesh, the control terminal 1 may also be used to implement the connection, specifically, when a bluetooth mesh connection is established between a certain bulb 2 and the control terminal 1, if the control terminal 1 also establishes a bluetooth mesh connection with another bulb 2 at this time, the user may control the two bulbs 2 to establish the bluetooth mesh connection through software on the control terminal 1, that is, to implement the networking of the bluetooth mesh, and after the user forms the bulbs 2 into a bluetooth mesh network, the control terminal 1 may only connect any one bulb 2 in the bluetooth mesh network, and may control all bulbs 2 in the bluetooth mesh network. It should be further noted that each bulb 2 may also record feature information of other bulbs 2 that have been connected to itself, so that after the bulb 2 is turned off and then restarted, the bulb 2 can automatically reestablish a bluetooth mesh connection with other bulbs 2 that have been connected to itself, for example, the bulb 2 may continuously send the feature information to the outside after being restarted, and simultaneously continuously receive the feature information sent by other bulbs 2, and when the bulb 2 detects that feature information of other bulbs 2 that have been connected to itself exists in the feature information, the bluetooth mesh connection between the two bulbs 2 is automatically established.

In summary, the control terminal 1 is connected with the N bulbs 2 through the bluetooth Mesh, where N is a positive integer, the processor in the control terminal 1 generates a corresponding light control instruction according to the music signal received by the processor, and then sends the light control instruction to the N bulbs 2 through the bluetooth Mesh function. Because control terminal 1 is connected with N bulb 2 through the bluetooth Mesh, can send light control command for all bulbs 2 simultaneously through the bluetooth Mesh, can control a plurality of bulbs 2, realized wireless connection between control terminal 1 and a plurality of bulbs 2 moreover, do not need extra wire rod to connect, improved the usability.

On the basis of the above-described embodiment:

as a preferred embodiment, the control terminal 1 further comprises a microphone, the processor is connected to the microphone, and before generating the corresponding light control command according to the music signal received by the processor, the method comprises:

when a starting instruction is received, starting to acquire a sound signal acquired by a microphone, and taking the acquired sound signal as a music signal;

after the music signal that receives according to the treater oneself generates corresponding light control instruction, still include:

and when a stop instruction is received, stopping acquiring the sound signals collected by the microphone.

In order to improve the applicability, in the present application, in order to expand the range of the music signal that can be received by the processor itself, a microphone is further disposed in the control terminal 1, and the processor can receive, through the microphone, not only the music signal sent by the control terminal 1 itself, but also the music signal sent by an external device. Specifically, when the control terminal 1 plays music, since the music instruction for playing the music is known by the control terminal 1 itself, the processor in the control terminal 1 may directly generate the corresponding light control instruction according to the music instruction, and when the external device plays music, the processor in the control terminal 1 acquires the music signal of the external device through the microphone and generates the corresponding light control instruction according to the music feature in the music signal.

Considering that the microphone may continuously collect external sound signals when the microphone works, when music is not played on the external device and the processor, that is, when the user does not play music, if the sound signals collected by the microphone are still obtained, the processor may use non-music signals such as external noise and environmental noise as music signals and generate corresponding light control instructions, and since the non-music signals are usually unstable, abnormal flickering and abnormal color change of the bulbs 2 may be caused, which affects user experience. Based on this, whether the sound signal collected by the microphone needs to be acquired or not is judged through an instruction, when a user starts playing music, a starting instruction can be triggered, the sound signal collected by the microphone is a real music signal, and when the user stops playing music, a stopping instruction is triggered to avoid collecting non-music signals. In addition, when receiving the music signal, the AudioToolBox may be used to convert the sound signal collected by the microphone into a digital music signal for subsequent processing, or may be used to convert the sound signal by using other software, which is not limited in this application. Therefore, the usability is improved by arranging the microphone and controlling whether the sound signal is acquired or not through the instruction.

As a preferred embodiment, before the sound signal is taken as a music signal, the method further comprises:

clearing non-music noise signals in the sound signals by using a preset noise reduction method;

and taking the sound signal without the non-music noise signal as a music signal.

In order to accurately acquire a music signal, in the present application, it is considered that in practical applications, besides a music signal played by a device, there may be other non-music signals in an environment, for example, when a vehicle whistles near the control terminal 1 or a house is decorated, whistling sounds and decoration noises are non-music signals, and when a microphone collects a sound signal, the microphone cannot collect only a real music signal played by the device without collecting the non-music signal, and the non-music signals may affect the accuracy of the processor for controlling the bulb 2 according to the real music signal played by the device. Based on this, after the sound signal collected by the microphone is acquired, a preset noise reduction method is first required to be used to remove the noise signal in the sound signal, specifically, the noise signal in some frequency bands in the sound signal may be removed, or a corresponding sound signal is emitted through a speaker to cancel the non-music noise signal. Based on the method, the non-music noise signals in the sound signals are eliminated through the preset noise reduction method, and the music signals can be accurately acquired.

As a preferred embodiment, the preset noise reduction method is wiener noise reduction.

Wiener filtering is a filtering method based on the minimum mean square error criterion, and is suitable for the environment of a required sound signal body which needs to be separated from noise mixed with a plurality of sound signals, namely the actual music signal played by equipment, and the mean square error between the actually output music signal after wiener filtering and the theoretically best output music signal is the minimum, so the wiener filtering is used as a preset noise reduction method, and the music signal can be accurately acquired.

As a preferred embodiment, the sending of the light control command to the N light bulbs 2 through the bluetooth Mesh includes:

determining M Bluetooth Mesh groups corresponding to N bulbs 2, wherein M is a positive integer and is smaller than N;

the light control instructions are sent to the M Bluetooth Mesh groups through the Bluetooth meshes respectively, so that the M Bluetooth Mesh groups send the light control instructions to the bulbs 2 corresponding to the M Bluetooth Mesh groups respectively.

In order to better realize that the control terminal 1 controls the plurality of bulbs 2 simultaneously, in the present application, it is considered that the N bulbs 2 all need to be connected to the control terminal 1, and the control terminal 1 can control the bulbs 2 simultaneously, and when the number of the bulbs 2 connected to the control terminal 1 at the same time is too large, the control terminal 1 may not control the bulbs 2 simultaneously and synchronously, that is, when the number of the bulbs 2 is too large, a situation of instruction delay may occur, resulting in that the light change effect of the bulbs 2 does not conform to the music atmosphere being played at present. Based on this, referring to fig. 3, fig. 3 is a flowchart of another method for controlling a plurality of light sources based on music provided by the present application, when performing bluetooth mesh networking on N bulbs 2, each X bulb 2 may be used as a group to form a bluetooth mesh group, so as to form M bluetooth mesh groups, where X and M are positive integers and X × M = N, the control terminal 1 is connected to the main units in the bluetooth mesh groups, and the purpose of simultaneously connecting the control terminal 1 and the N bulbs 2 is achieved through connection between the main units of the bluetooth mesh groups and the bulbs 2. Based on this, through establishing a plurality of bluetooth mesh groups, can realize better that control terminal 1 controls a plurality of bulbs 2 simultaneously.

As a preferred embodiment, the light control command includes one or more of a combination of a light bulb 2 brightness control command, a light emission color control command, and a light bulb 2 blinking frequency control command.

In order to make the light emission of the bulb 2 more accord with the music atmosphere, in the present application, the illumination intensity of the bulb 2 is controlled by the brightness control instruction of the bulb 2, so that the illumination intensity of the bulb 2 changes along with the music atmosphere, for example, when the music being played at present is a relaxing music, the illumination intensity may be set to be in the form of a breathing lamp, and the illumination intensity periodically and gradually brightens and then gradually darkens in the shape of a sine wave, so that the illumination intensity accords with the relaxing music atmosphere; the lighting color of the bulb 2 is controlled through the lighting color control instruction, so that the lighting color of the bulb 2 is changed along with the atmosphere of the music, for example, when the music being played at present is a relaxing music, the lighting color of the bulb 2 can be set to be a warm color such as orange or brown, so that the lighting color conforms to the atmosphere of the relaxing music; the flickering frequency of the bulb 2 is controlled through the flickering frequency control instruction of the bulb 2, for example, when music which is played at present is music with strong rhythm, the flickering frequency can be increased when the music rhythm is enhanced, and the flickering frequency is reduced when the rhythm is weakened; in addition, the light linkage can be further set to be carried out between the plurality of bulbs 2, so that the plurality of bulbs 2 are combined to show the functions of patterns and the like formed by the bulbs 2, and the application does not limit the functions. Accordingly, by controlling the brightness, color, and blinking frequency of the bulb 2, the light emitted by the bulb 2 can be made to more closely match the atmosphere of music.

As a preferred embodiment, generating the corresponding light control instruction according to the music signal received by the processor itself includes:

and generating a corresponding light control instruction according to one or more combinations of the volume level, the sound frequency, the music type and the volume change frequency corresponding to the music signal.

In order to generate an accurate light control instruction, in the application, because different music is played with different volumes and different volume change speeds, the light bulb 2 is controlled according to the volume of the music, so that the light can change along with the change range and the change speed of the volume, for example, a slow music generally has a small change range and a slow change speed of the overall volume, while a music with strong rhythm sense generally has a large change range of the volume and the volume can be ignored; the sound frequencies of different instruments playing music and the frequency ranges of the instruments are different, the lamp bulb 2 is controlled according to the sound frequencies of the music, so that light can be changed along with the frequencies, for example, the sound frequency of a drum is generally in a lower frequency band, the sound frequency of a violin is generally in a higher frequency band, an instrument corresponding to the currently played music can be determined according to the currently played sound frequency, and the light effect of the lamp bulb 2 is controlled according to the types of the instruments to be in accordance with the style of the instrument; the music type can be determined according to the music characteristics such as sound frequency, music rhythm, human voice lines, melody and the like, and after the music type of the currently played music is determined, the bulb 2 can be controlled according to the type of the currently played music, so that the lighting effect of the bulb 2 accords with the style and atmosphere of the music. Based on this, according to volume level, sound frequency, music type and volume change frequency, can generate accurate light control instruction.
