All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

As shown in fig. 1, the present invention provides a K song system, which includes a sound 21 disposed outside a vehicle 2, and a microphone 11, a receiving module 12, a vehicle-mounted host 13 and an in-vehicle sound 14 mounted in a vehicle 1; wherein, the vehicle interior 1 refers to the vehicle interior of an automobile. The vehicle exterior 2 refers to the vehicle exterior of an automobile. Further, the microphone 11 and the receiving module 12 may be disposed in a glove box of the vehicle interior 1, and the in-vehicle main unit 13 may be disposed on the middle tunnel. The car outside sound 21 is arranged outside the car 2, and a user can randomly put the position of the sound 21.

The vehicle-mounted host 13 is connected with the receiving module 12 and the vehicle-mounted sound equipment 14; further, the in-car audio 14 includes a power amplifier module connected to the in-car host 13 and a speaker connected to the power amplifier module, and the sound (such as a first to-be-played audio mix mentioned later) that needs to be played by the in-car audio 14 in the car 1 is output to the speaker through the power amplifier module for playing. The power amplifier module can be arranged in the trunk, and the loudspeaker can be arranged on the front instrument desk and four doors of the automobile. The receiving module 12 may be a dongle (dongle or dongle) receiver. The receiving module 12 can be plugged into the vehicle-mounted host 13 via a USB (Universal Serial Bus ) or integrated in the vehicle-mounted host 13. The receiving module 12 is externally connected with the vehicle exterior sound equipment 14 with the sound mixing function, so that the effects of high volume and high quality sound playing can be realized on the exterior and the interior of the vehicle, and meanwhile, the interface of the vehicle exterior sound equipment 14 is not required to be increased on the vehicle-mounted host 13.

The receiving module 12 is in signal connection with the microphone 11; the receiving module 12 is in signal connection with the vehicle exterior sound equipment 21; it will be appreciated that the above-mentioned K-song system supports two or even a plurality of microphones 11 and K-songs at the same time, that is, the number of the microphones 11 may be set to one, two or more according to the requirement, each microphone 11 may be disposed in the vehicle interior 1 or the vehicle exterior 2, for example, the plurality of microphones 11 may be disposed in the vehicle interior 1 or the vehicle exterior 2 entirely, or a part of the plurality of microphones 11 may be disposed in the vehicle interior 1, another part of the plurality of microphones may be disposed in the vehicle exterior 2 for use, and all of the microphones 11 are connected to the receiving module 12, in a preferred embodiment, the receiving module 12 is connected to the microphones 11 through a UHF (ultra high frequency radio wave) signal in a wireless communication manner; specifically, a RF (Radio Frequency) transceiver unit is provided on the microphone 11 and the receiving module 12 for transmitting and receiving UHF signals therebetween. Further, the receiving module 12 is connected to the car audio 21 through a 2.4GHz wireless signal communication. Specifically, the receiving module 12 is provided with a first wireless communication unit 121, the external sound box 21 is provided with a second wireless communication unit 211, and the first wireless communication unit 121 and the second wireless communication unit 211 are connected through 2.4GHz wireless signal wireless communication. Understandably, in the present invention, the receiving module 12 is connected with the microphone 11 through UHF signal wireless communication, and meanwhile, the receiving module 12 is connected with the car exterior sound 21 through 2.4GHz wireless signal wireless communication, and the delay of the 2.4GHz transmission technology and the delay of the UHF transmission technology are smaller, so that the phenomenon that the sound production of the car interior and the sound production of the car exterior are not synchronous can be avoided, and the low delay synchronous K song of the car interior and the car exterior is realized.

The receiving module 12 is configured to receive the voice data transmitted by the microphone 11, and input the voice data to the vehicle-mounted host 13 and the external sound 21 from two paths respectively; that is, as long as there is voice data input by the user through the microphone 11, at this time, the voice data is picked up by the microphone 11 and is transmitted to the receiving module 12, and then the receiving module 12 outputs the voice data synchronously through two paths, one path is input to the on-vehicle host 13 located in the vehicle 1, and the other path is input to the sound equipment 21 located outside the vehicle 2.

As shown in fig. 2, the in-vehicle host 13 is configured to perform the steps of:

s10, receiving a K song command containing a K song accompaniment to be played, and acquiring voice data transmitted by the receiving module 12; after the user finishes singing, the karaoke instruction is an instruction generated by the vehicle-mounted host 13 after determining that the karaoke accompaniment to be played corresponds to the song to be played (it is understood that the karaoke accompaniment to be played can be a complete song containing voice or can be only accompaniment music, and various parameters related to the karaoke such as the tone, the volume and the like of the karaoke accompaniment to be played can be adjusted in the karaoke process), for example, after selecting the song corresponding to the karaoke accompaniment to be played on the vehicle-mounted display screen, a preset button is triggered to generate the karaoke instruction; after voice requesting (determining a song corresponding to a K song accompaniment to be played through voice recognition) is completed through voice data input through the microphone 11, a K song command including the K song accompaniment to be played may be automatically generated.

It is understandably that after receiving the K song command, it is described that the process has entered the K song, so that it is necessary to first obtain the voice data recorded by the microphone 11 through the receiving module 12, further, the receiving module 12 is further configured to, after receiving the voice data input by the microphone 11, perform echo cancellation and noise reduction processing on the voice data, and input the voice data obtained after the processing to the in-vehicle host 13 and the out-vehicle stereo 21 from two paths respectively. Specifically, the microphone 11 (may be located in the vehicle interior 1 or/and the vehicle exterior 2) inputs the voice data to the receiving module 12 of the vehicle interior 1 by using the UHF signal, and the voice data is input to the vehicle-mounted host 13 all the way after echo cancellation, noise reduction processing, and the like are performed in the receiving module 12, and is input to the sound equipment 21 of the vehicle exterior 2 all the way.

S20, mixing the K song accompaniment to be played and the voice data in the vehicle-mounted host 13, and playing the obtained first mixed voice to be played through the in-vehicle sound 14; that is, when the vehicle-mounted host 13 receives the voice data, the K song accompaniment to be played and the received voice data are mixed to obtain a first to-be-played mixed sound, and the first to-be-played mixed sound is output to the in-vehicle sound 14 located in the vehicle 1 for playing. An SDK (software development kit) package is embedded in the vehicle-mounted host 13, so that the mixing processing of the K song accompaniment to be played and the received voice data in the vehicle-mounted host 13 is realized through the SDK package, meanwhile, a K song applet can be generated through the SDK package, and sound effect selection, volume adjustment of the microphone 11, reverberation intensity adjustment and the like can be performed through the K song applet.

S30, inputting the K song accompaniment to be played to the car outside sound 21 through the receiving module 12, so that the car outside sound 21 mixes the received voice data with the K song accompaniment to be played, and further synchronously playing the obtained second mixed sound to be played and the first mixed sound to be played. That is, the vehicle-mounted host 13 mixes the K song accompaniment to be played and the received voice data to obtain a first to-be-played mixed sound, and inputs the K song accompaniment to be played to the sound box 21 through the receiving module 12, so that the voice data and the K song accompaniment to be played are mixed in the sound box 21, and the obtained second to-be-played mixed sound is played in the sound box 21 located outside the vehicle 2 (so as to realize synchronous playing of the first to-be-played mixed sound and the first to-be-played mixed sound).

Understandably, in the above process, because the voice data is subjected to echo cancellation, noise reduction processing and the like in the receiving module 12 before being output from two paths through the receiving module 12, the voice data output from the receiving module 12 to the vehicle interior 1 or the vehicle exterior 2 has high-quality sound effects; and the receiving module 12 outputs the voice data synchronously from two paths, and can synchronously mix the voice data and the K song accompaniment to be played in the vehicle-mounted host 13 and the sound box 21, so that the low-delay and high-volume sound effect can be obtained no matter the user is in the vehicle 1 or 2K songs outside the vehicle. After the Karaoke system receives a Karaoke instruction from the vehicle-mounted host 13, voice data are picked up by the microphone 11 and are input and transmitted to the receiving module 12, and then the receiving module 12 synchronously outputs the voice data through two paths, wherein one path of voice data is input to the vehicle-mounted host 13 positioned in the vehicle 1, and the other path of voice data is input to the sound 21 positioned outside the vehicle 2; at this time, when receiving the voice data, the vehicle-mounted host 13 mixes the K song accompaniment to be played with the received voice data to obtain a first to-be-played mixed sound, and outputs the first to-be-played mixed sound to the in-vehicle sound 14 located in the vehicle 1 for playing; meanwhile, the vehicle-mounted host 13 inputs the K song accompaniment to be played to the sound 21 through the receiving module 12, and then the voice data and the K song accompaniment to be played are subjected to sound mixing processing in the sound 21, so that the obtained second sound to be played is played in the sound 21 positioned outside the vehicle 2 (the first sound to be played is synchronously played with the first sound to be played), thus, through the K song system, the sound synchronization and the low-delay playing after the sound mixing of the 1-in-vehicle and the 2-K song outside the vehicle can be realized, when the microphone 11K song (or the speech and the like) is used outside the vehicle 2, the effect that the 1-in-vehicle and the 2-in-vehicle have large volume and high quality sound playing simultaneously can be realized, and the use experience of the 1-in-vehicle outside of a user is greatly improved. The K song system provided by the invention realizes the coverage of the whole scene of 2K songs outside the vehicle 1, achieves the synchronous sounding of the 2-in-vehicle sound 21 and the 1-in-vehicle sound 14 in the vehicle, has low delay, and meets the requirements of large volume of the 1-in-vehicle and 2-K songs outside the vehicle.

In an embodiment, as shown in fig. 3, the K song system further includes a light controller 15 and an atmosphere lamp panel 16 disposed in the vehicle 1, where the atmosphere lamp panel 16 is connected to the vehicle-mounted host 13 through the light controller 15; further, a light controller 15 and an atmosphere light panel 16 are arranged in the vehicle interior 1 instrument desk.

The in-vehicle host computer 13 is further configured to be configured to:

after receiving a K song instruction, acquiring beat information in the K song accompaniment to be played; that is, in the process of starting the K song in response to the K song instruction, the in-vehicle host 13 captures beat information in the K song accompaniment to be played while playing the K song accompaniment to be played. The beat information is sent to the light controller 15, so that the light controller 15 controls the atmosphere lamp panel 16 to execute light music interaction operation according to the beat information. That is, beat information in the K song accompaniment to be played, which is captured by the vehicle-mounted host 13, will be used to instruct the light controller 15 to control the atmosphere light panel 16 to perform the light music interaction operation. The lamplight-music interaction operation refers to lamplight with continuously changing color and brightness and even light emitting angle of the atmosphere lamp panel 16, so that the lamplight-music interaction operation is matched with the beat information, a better lamplight rhythm effect is provided for a user of K songs, and user experience is improved. The embodiment can meet the use requirements of multiple scenes of a user, can realize the music rhythm of the atmosphere lamp according to the music beats in the vehicle 1, and can set the atmosphere sense in the vehicle 1.

Further, the in-vehicle host computer 13 is further configured to be configured to:

and generating RGB and brightness CAN messages according to the beat information, recording the RGB and brightness CAN messages as light control information and sending the light control information to the light controller 15, so that the light controller 15 controls the atmosphere lamp panel 16 to execute light music interaction operation according to the beat information through a LIN bus.

That is, in this embodiment, after the audio node is calculated by the attack detection algorithm (i.e. fourier transform), the beat information of the K song accompaniment to be played is obtained, and the beat information CAN be converted into RGB and brightness CAN messages according to the preset CAN message conversion algorithm, and output to the light controller 15, the light controller 15 outputs the beat information to the atmosphere lamp panel 16 through the Lin bus (a low-cost serial communication network defined for the automotive distributed electronic system), so that the atmosphere lamp panel 16 performs light rhythms (i.e. performs light music interaction operation) along with different music beats, the light music interaction operation refers to the light with continuously changing color and brightness of the atmosphere lamp panel 16, even the light emitting angle is further matched with the above beat information, so as to provide better light rhythmic effect for the user of the K song), and provide a strong atmosphere sense for the K song, so that the user feels as immersive experience as in KTV in the vehicle 1.

In one embodiment, as shown in fig. 3, the K song system further includes a projector 22 disposed outside the vehicle 2; wherein the projector 22 is arranged outside the vehicle 2, and a user can randomly put the position of the projector 22; the projector 22 is connected with the vehicle-mounted host 13; the projector 22 and the display screen are both connected with the vehicle-mounted host 13; further, the projector 22 and the on-vehicle host 13 are connected through WiFi signal wireless communication, and it is understood that the projector 22 and the on-vehicle host 13 may also be connected wirelessly through other wireless signals, or may be electrically connected through a connection line.

The in-vehicle host computer 13 is further configured to be configured to:

after receiving the K song command, display data corresponding to a vehicle-mounted display screen (the vehicle-mounted display screen is mounted at a preset position of the vehicle interior 1 and is connected with the vehicle-mounted host 13, the vehicle-mounted display screen can be used for displaying vehicle driving information when the vehicle is driving, when the vehicle is performing K songs through the K song system, a display picture of the K songs can be played in the vehicle interior 1) is displayed, and the display data is transmitted to the projector 22 through a preset projection screen protocol (such as Miracast projection screen protocol, so that a projection picture of the vehicle interior 1 display picture is projected to the outside 2 of the vehicle) so that the projector 22 synchronously projects a projection picture consistent with the display picture outside 2 of the vehicle. That is, after receiving the K song instruction to start the K song, the display data displayed on the display screen may be synchronously transmitted to the projector 22 for projection. That is, in this embodiment, in order to meet the use requirement of the user for multiple scenes of the K song system, the projector 22 is added to the outside 2 of the vehicle, when the user is 2K songs outside the vehicle, the projector 22 is powered by 220V of the vehicle, and the WiFi hot spot of the vehicle-mounted host 13 is used for sharing the network between the projector 22 and the vehicle-mounted host 13 through WiFi signals, so that the vehicle-mounted display screen of the inside 1 and the projector 22 of the outside 2 of the vehicle project consistent K song display images and projection images through the Miracast projection protocol, and the problem that the K song display images are invisible to the outside 2 of the vehicle is avoided.

In an embodiment, the in-vehicle host 13 is further configured to be configured to:

receiving a voice recognition instruction, and performing voice recognition on the voice data transmitted by the receiving module 12 to obtain voice indication information; it will be appreciated that the speech recognition instruction may be generated in different ways, for example when the user is in the vehicle 1; for another example, in the vehicle interior 1 or the vehicle exterior 2, the user can generate a voice recognition instruction by triggering a preset key set on the microphone 11; even, the voice recognition instruction can be generated by sending a voice trigger instruction to other voice recognition modules originally arranged on the automobile, for example, the automobile is originally provided with a voice recognition module for recognizing the voice of the driver to obtain the command for controlling the automobile in the driving process of the automobile, at this time, the voice trigger instruction (such as 'hello, XXX, voice song requesting opening') which is preset can be input into the voice recognition module through the microphone 11, and then the voice recognition instruction can be automatically generated through the voice recognition module on the automobile. After receiving the voice recognition instruction, the on-vehicle host 13 needs to perform voice recognition on the voice data transmitted by the receiving module 12 to obtain voice instruction information. Understandably, before the above-described voice recognition, the human voice data has undergone echo cancellation, noise reduction processing, and the like in the receiving module 12, in which the environmental sound, noise, and the like are canceled, and thus the human voice (dry sound) is inputted to the in-vehicle host computer 13.

Determining a voice instruction according to the voice instruction information; that is, the voice indication information may be a voice command or may be other content, such as a car control command or other irrelevant content, so that further determination needs to be made on the voice indication information, and it is understood that, when the voice indication information is a car control command indicating that the car is running, the car control command corresponding to the voice indication information will be regarded as an invalid command (because when receiving a K song command to perform a K song, the car can only be in a non-running state and only receive a command related to the K song, and the car must be set to be unable to execute the car control command at this time); similarly, identifying other irrelevant contents (such as daily talking content of people) can prompt the occurrence of an invalid instruction, and after the invalid instruction occurs, the user can further prompt the re-input of a voice instruction or prompt that the voice recognition fails; in the invention, all voice commands can be set according to the requirements, such as a song requesting command, a song cutting command (the last one or the next one, etc.), a volume adjusting command, etc.

When the voice instruction is a song requesting instruction containing a target song name, uploading the target song name to a cloud server, and receiving song searching information fed back by the cloud server; the song search information is generated after the cloud server matches a preset song name corresponding to the target song name in a preset song library list; that is, when the voice command is a song-order command, a target song name must be identified by voice in the song-order command, at this time, the identified target song name contained in the song-order command may be uploaded to the cloud server, the cloud server compares the target song name with a preset song library list stored in the cloud server in advance, the preset song library list includes a plurality of preset song names, and the song corresponding to each preset song name may be obtained by searching through a preset application program in the vehicle-mounted host 13, and the searched song may be played as a K song accompaniment to be played (for example, playing after performing the audio mixing process with the voice data in steps S20 and S30). Understandably, after the cloud server matches the preset song name corresponding to the target song name in the preset song library list, the cloud server feeds back a song search information to the vehicle-mounted host 13 under the condition that communication is normal, so as to inform the vehicle-mounted host 13 of the matching result, that is, the song search information can represent whether the preset song name corresponding to the target song name is successfully matched at present. Understandably, the searching and matching in the cloud server can reduce the workload of the vehicle-mounted host 13, ensure the running speed of the vehicle-mounted host 13 and reduce the energy consumption of the vehicle-mounted host 13.

It can be understood that in the above process, the target song name is compared with each preset song name in the preset song library list, and when the preset song name with the word matching degree of 100% (the two are completely consistent) of the target song name exists in the preset song library list, song search information representing that the target song name has been successfully matched with the preset song name corresponding to the target song name is directly generated and sent to the vehicle-mounted host 13. When the word matching degree of the preset song names and the target song names in the preset song library list is less than 100%, if the preset song names with the word matching degree exceeding the preset matching degree threshold value do not exist, the song requesting failure is directly prompted; if the word matching degree of the target song name exceeds the preset song name of the preset matching degree threshold value, song search information representing that the target song name is successfully matched with the preset song name corresponding to the target song name is generated and sent to the vehicle-mounted host 13, at this time, the song search information contains a preset number (such as the first three) of preset song names (the preset number of preset song names are required to be arranged according to the word matching degree from large to small), the vehicle-mounted host 13 can sequentially play the preset number of preset song names according to the word matching degree through the sound 21 or/and the in-vehicle sound 14 of the vehicle 1 from large to small, after the voice confirmation information is input through the microphone 11, and after the voice information input by the user for the preset song name of the current playing is acquired again, the user is confirmed according to the voice information, the song-on-demand failure is prompted, and understandably, when the voice information contains one of the preset song names, the user is confirmed to be required to play the song corresponding to the preset song name, the preset song name is directly carried out by the user, after the preset application in the host 13 is searched for obtaining the preset song name in sequence, the preset song name is searched for playing, and the preset song name is required to be played as a song-on-board song name; when the voice information does not include any one of the played preset song names (for example, the voice information is "re-song-requesting" or "none of the above" is ") the present song-requesting failure is represented, and a new voice recognition instruction is generated again at this time, and further the voice data transmitted by the receiving module 12 needs to be subjected to voice recognition again to obtain new voice indication information.

And searching a song corresponding to the target song name through a preset application program when the song search information representation is successfully matched with the preset song name corresponding to the target song name, recording the searched song as a K song accompaniment to be played, and generating a K song command containing the K song accompaniment to be played. That is, after the cloud server matches the preset song name corresponding to the target song name in the preset song library list, the vehicle-mounted host 13 searches for songs according to the preset song name returned by the cloud server, and plays the songs. Understandably, the vehicle-mounted host 13 is provided with an intelligent voice engine, after the intelligent voice engine acquires clean voice data subjected to echo cancellation and noise reduction processing by the receiving module 12, the voice engine can identify a target song name and then upload the target song name to the cloud server, a preset song library list in the cloud server can be updated as required, the intelligent voice engine feeds back song search information at the cloud server, after the song search information characterization is successfully matched with the preset song name corresponding to the target song name, the intelligent voice engine responds to the song search information requirement to search a song corresponding to the preset song name through a preset application program, and then the song is used as a K song accompaniment to be played so as to complete playing (after the 1-vehicle-outside-2 synchronous processing of the vehicle carries out the voice mixing processing on the K song accompaniment to be played and the voice data, the low-delay synchronous playing is realized).

In this embodiment, when the user is 1K song in the car, the K song microphone 11 can cooperate with the preset application program to realize voice song requesting, and the user easily gets rid of the trouble that needs to perform both hands touch song requesting on the preset display screen of the car 1 or scan the code song requesting through the intelligent terminal, so that the user experience is further improved, and the effect of singing is achieved. In an embodiment, the in-vehicle host 13 is further configured to be configured to:

after determining the voice instruction according to the voice instruction information, if the voice instruction is a preset karaoke operation instruction (other karaoke related function operation instructions except the karaoke instruction), executing a preset function operation corresponding to the karaoke operation instruction. In this embodiment, that is, when the above-mentioned slave voice instruction information is a voice instruction, if the voice instruction is a preset K song operation instruction other than the song requesting instruction, at this time, a K song related operation (that is, a preset function operation) corresponding to the preset K song operation instruction may be executed by the intelligent voice engine, and it is understood that the preset K song operation instruction may be set according to a requirement, for example, the preset K song operation instruction includes, but is not limited to, a song cutting (previous or next, etc.) instruction, a pause instruction, or a volume adjustment instruction. The embodiment can easily realize the functional operations of song requesting, song cutting and the like with the voice indication.

It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic, and should not limit the implementation process of the embodiment of the present invention. Each of the above-described modules in the in-vehicle host 13 may be implemented in whole or in part by software, hardware, and a combination thereof, so as to perform operations corresponding to each of the above-described modules.

The invention also provides an automobile comprising the Ksong system.

After the K song system of the automobile receives the K song instruction, the voice data are picked up by the microphone 11 and are input to the receiving module 12, and then the receiving module 12 synchronously outputs the voice data through two paths, wherein one path of voice data is input to the on-board host 13 positioned in the automobile 1, and the other path of voice data is input to the sound 21 positioned outside the automobile 2; at this time, when receiving the voice data, the vehicle-mounted host 13 mixes the K song accompaniment to be played with the received voice data to obtain a first to-be-played mixed sound, and outputs the first to-be-played mixed sound to the in-vehicle sound 14 located in the vehicle 1 for playing; meanwhile, the vehicle-mounted host 13 inputs the K song accompaniment to be played to the sound 21 through the receiving module 12, and then the voice data and the K song accompaniment to be played are subjected to sound mixing processing in the sound 21, so that the obtained second sound to be played is played in the sound 21 positioned outside the vehicle 2 (the first sound to be played is synchronously played with the first sound to be played), thus, through the K song system, the sound synchronization and the low-delay playing after the sound mixing of the 1-in-vehicle and the 2-K song outside the vehicle can be realized, when the microphone 11K song (or the speech and the like) is used outside the vehicle 2, the effect that the 1-in-vehicle and the 2-in-vehicle have large volume and high quality sound playing simultaneously can be realized, and the use experience of the 1-in-vehicle outside of a user is greatly improved.
