Detailed Description

The embodiment of the application provides an audio host which can be a karaoke host in a karaoke system, a live broadcast host in a live broadcast system and the like, so that the audio host can be applied to an individual karaoke scene, an individual live broadcast scene, a multi-person indoor or outdoor karaoke scene and the like, and the detailed description will be made for various scenes.

The audio host and the intelligent device are matched for use, the audio host is used for processing audio and video data, and the intelligent device is used for realizing interaction between a user and a server. The intelligent device can be a smart phone, a tablet computer, a notebook computer and the like.

The following audio terms are used in the description of the present scheme:

dry sound, also called naked sound, generally refers to pure human sound which is not subjected to any post-processing and processing after being recorded in the karaoke process, is direct sound from a microphone to an audio host, and has no redundant sound effect or reverberation in the middle. In the process of singing K, the dry sound is the voice sung by the user of the singing K.

Wet sound, as opposed to dry sound, refers to post-processed human voice recording. In order to improve the user experience during singing, the dry sound needs to be processed in the later stage (such as operations of reverberation, modulation, pressure limitation, speed change and the like), and the sound processed in the later stage is the wet sound.

The sound effect processing is a processing process of converting dry sound into wet sound by the audio host based on a sound effect mode selected by a user, and the sound effect mode can comprise changing female sound into male sound, changing male sound into female sound, changing doll sound and the like.

The mixing process is to integrate the sound from multiple sources into a stereo track or a mono track. In the process of singing, the mixed sound signal sources are mainly two: accompaniment music and the voice of a K singer, the below-mentioned remix process may be a process of integrating accompaniment and wet sound.

The ear return is the process that the mixed audio processed by sound effect processing and sound mixing processing enters the ears of the K singer in the K singing process or the live broadcasting process of the K singer. The faster the return to the ear, the smaller the return to the ear delay, the better the user experience.

The K sings are scored, the K singing software can give a score according to the levels of the K singers in various aspects such as tone accuracy, rhythm, breath, singing and the like, the score is used for guiding and encouraging the K singing level of the user, and the function is to score the dry tones of the K singers.

The audio host will be described below, and as shown in fig. 1, the audio host includes a case 1, an audio chip 2, a sound component 3, a microphone connecting component 4, and a smart device connecting component 5; the audio chip 2, the sound component 3, the microphone connecting component 4 and the intelligent device connecting component 5 are all positioned in the case 1; the audio chip 2 is respectively and electrically connected with the sound component 3, the microphone connecting component 4 and the intelligent equipment connecting component 5; the microphone connecting part 4 is configured to establish a communication connection relationship with at least one microphone 10, and the smart device connecting part 5 is configured to establish a communication connection with the smart device 20.

The case 1 is a housing of the audio host, and is configured to protect components inside the audio host.

In one example, as shown in fig. 2, the cabinet 1 may be a hexahedral box shape or a box shape in shape. In size, the audio host can be a portable host, and the size is smaller, so that a user can conveniently carry the audio host. In other examples, the audio host may also be a desktop host, and the user may be placed at home as a home appliance.

The audio chip 2 of the audio host may be a DSP (Digital Signal processing) chip for performing audio processing, for example, the audio chip 2 has an audio processing function and a sound mixing processing function.

In an example, the audio chip 2 has an audio processing function, and can obtain the audio desired by the K singer through any existing audio processing mode, thereby improving the experience of the K singing. For example, in the sound effect processing of sound variation, the audio chip 2 may realize sound variation by adjusting the frequency of the dry sound data, or adjusting the frequency and the speech rate of the dry sound data. It should be noted that the sound effect processing function is implemented by the existing method (such as software program or hardware circuit), and the sound effect processing process is not improved in the present application.

In one example, the audio chip 2 has a mixing function, and can integrate sounds from multiple sources into one stereo track or mono track. For example, the voice of a person singing a K singer and the voice of accompanying music can be integrated into one stereo track or monophonic track. It should be noted that the mixing processing function is implemented by an existing method (such as a software program or a hardware circuit), and the mixing processing process is not improved in the present application.

In one example, the audio chip 2 may be a DSP chip in which the sound effect processing function and the sound mixing processing function, etc. are integrated.

In another example, as shown in fig. 3, the audio chip 2 may include a sound-effect processing section 21 and a mixing processing section 22, an input terminal of the sound-effect processing section 21 being connected to an output terminal of the microphone connecting section 4, and an output terminal of the sound-effect processing section 21 being connected to the mixing processing section 22.

Wherein, audio processing unit 21 is the DSP chip, and audio mixing processing unit 22 also is the DSP chip, and audio processing process is carried out by an independent DSP chip, and audio mixing processing process is also carried out by an independent DSP chip, can accelerate audio processing and audio mixing processing to can accelerate the ear speed of returning, reduce the ear and return and postpone, promote user's use and experience.

In one example, the sound effect mode can be selected by the user himself, and accordingly, as shown in fig. 4, the audio host further includes a sound effect part 7, the sound effect part 7 is located in the case 1 and electrically connected to the audio chip 2, for example, the sound effect part 7 is electrically connected to the sound effect processing part 21 of the audio chip 2.

The sound effect part 7 is configured to receive an operation instruction triggered by a user, convert the operation instruction into a sound effect signal, and send the sound effect signal to the audio chip 2, so that the audio chip 2 performs sound effect processing, where the operation instruction carries a sound effect mode selected by the user.

For example, when the user performs an operation of selecting an audio mode, the audio component 7 can receive an operation instruction performed by the user, convert the operation instruction into an audio signal that can be recognized by the audio processing component 21, and then send the audio signal to the audio processing component 21, so that the audio processing component 21 can perform audio processing according to the audio signal.

The audio host can also upload the sound effect mode selected by the user to the server through the intelligent device 20, and sound effect processing is carried out by the server. Correspondingly, after the sound effect processing part 21 of the audio chip 2 receives the sound effect signal sent by the sound effect part 7, a part of the sound effect signal is used for sound effect processing, and the other part of the sound effect signal can be uploaded to the server through the intelligent device 20 and then is subjected to sound effect processing by the server.

In one application, the user may trigger the operation command through the sound effect keys, and accordingly, as shown in fig. 4, the audio host includes a sound effect keyboard 8, the sound effect keyboard 8 and the sound effect unit 7 have a communication connection relationship therebetween, the sound effect keyboard 8 includes a plurality of keys, each key represents a sound effect mode, for example, a first key of the sound effect keyboard 8 represents a sound effect mode of male sound changing into female sound, a second key represents a sound effect mode of female sound changing into male sound, and a third key represents a sound effect mode of baby changing into male sound. In this way, the user can select a desired sound effect on the sound effect keyboard 8.

For example, the sound effect part 7 stores in advance the corresponding relationship between the key identifiers of the sound effect keyboard 8 and the sound effect signals, wherein the keys correspond to the key identifiers one to one, and the key identifiers correspond to the sound effect signals one to one. After a user clicks a first key in the sound effect keyboard 8, when the sound effect part 7 receives an operation instruction which carries a first key identifier and is triggered by the first key, a first sound effect signal corresponding to the first key identifier is determined through the corresponding relation between the key identifier and the sound effect signal, the first sound effect signal is sent to the sound effect processing part 21, and after the sound effect processing part 21 receives the first sound effect signal, dry sound data input by the user is processed based on the first sound effect signal.

For example, the sound effect mode represented by the first key in the sound effect keyboard 8 is a male sound changing into a female sound, after the sound effect processing unit 21 receives the first sound effect signal corresponding to the first key identifier, the frequency of the dry sound data input by the user is adjusted by increasing eight degrees to obtain wet sound data, and the wet sound data is played by the sound component 3, so that the sound played by the sound component 3 is a female sound.

It is to be noted that if an operation instruction triggered by the prominence keyboard 8 can be recognized by the prominence processing section 21, the prominence keyboard 8 may directly send a signal indicating a prominence mode to the prominence processing section 21. On the other hand, if the operation instruction triggered by the acoustics keyboard 8 can not be recognized by the acoustics processing unit 21, the operation instruction triggered by the acoustics keyboard 8 can be converted into a signal which can be recognized by the acoustics processing unit 21 by the acoustics unit 7.

Wherein, the sound effect keyboard 8 and the sound effect part 7 can be in wireless connection, or can also be in wired connection.

For example, the sound effect keyboard 8 may be electrically connected to the sound effect section 7 in the cabinet 1 through a USB (Universal Serial Bus) interface. As shown in fig. 5, a USB port 11 corresponding to the USB interface is disposed on a wall of the case 1, and the sound effect keyboard 8 may be connected to the USB port corresponding to the USB port 11 through a data line.

In order to input audio data into the audio host, as shown in fig. 4, the audio host includes a microphone connecting part 4, and the microphone connecting part 4 is located in the case 1 and used for establishing a communication connection relationship with the microphone 10.

The audio host can include a microphone or not, and the user can use the audio host in cooperation with the microphone without the microphone.

In one example, the microphone 10 and the microphone connecting part 4 may be a Wireless connection, such as a bluetooth connection, a Wi-Fi (Wireless Fidelity) connection, or the like. The microphone 10 and the microphone connecting part 4 may be connected by a wire, for example, the microphone 10 and the microphone connecting part 4 may be connected by a data line for communication.

In this embodiment, the specific connection mode between the microphone 10 and the microphone connection component 4 is not limited, and technicians may flexibly select the connection mode according to actual requirements.

In one example, in general, the audio signal output by the microphone 10 is an analog signal, after the audio signal output by the microphone 10 is received by the microphone connecting part 4, the analog signal needs to be converted into a digital signal and then sent to the sound effect processing part 21 of the audio chip 2, and after the sound effect processing part 21 completes the sound effect processing, a wet sound is obtained and sent to the mixing processing part 22. The mixing processing unit 22 receives the wet sound, and performs integrated mixing processing on the wet sound and the accompaniment selected by the K singer to obtain a mixed audio. And sends the mixed audio to the audio part 3. The description of the microphone connecting member 4 is also applicable to the above and below embodiments.

As shown in fig. 6, the audio component 3 may include a built-in speaker 32, and the built-in speaker 32 may be exposed from the casing 1 so as to output audio data to the outside. Alternatively, the built-in speaker 32 is located in the chassis 1, and the chassis 1 has a feed hole 12 at a position opposite to the built-in speaker 32, so that the audio data output by the built-in speaker 32 can be played through the feed hole 12, as shown in fig. 5.

As shown in fig. 6, the acoustic unit 3 includes not only the built-in speaker 32 but also an audio processing unit 33 and a power amplifier 34, etc., wherein an input terminal of the audio processing unit 33 is connected to an output terminal of the mixing processing unit 22, an output terminal of the audio processing unit 33 is connected to an input terminal of the power amplifier 34, and an output terminal of the power amplifier 34 is connected to the built-in speaker 32.

The audio processing unit 33 is configured to perform some audio data processing, such as digital-to-analog conversion, digital signal conversion into analog signal, and equalizer function.

Thus, the mixed audio obtained after the mixing processing unit 22 of the audio chip 2 completes the mixing processing can be transmitted to the audio processing unit 33 of the audio component 3, and the audio processing unit 33 can convert the digital signal into an analog signal, send the mixed audio after the digital-to-analog conversion to the power amplifier 34, perform the amplification processing by the power amplifier 34, and then play the mixed audio to the outside through the built-in speaker 32.

In one example, in order to connect the external player, as shown in fig. 6, the audio component 3 further includes an audio output component 31, and the audio output component 31 may be an interface component, and is located in the case 1 for establishing a communication connection relationship with the external player 30.

In one example, the audio output component 31 and the external player 30 may be connected wirelessly, for example, a bluetooth connection, a Wi-Fi (Wireless Fidelity) connection, or the like. The audio output component 31 and the external player 30 may also be connected by a wire, and accordingly, as shown in fig. 7, the cabinet wall of the cabinet 1 has an audio output port 13 at a position corresponding to the audio output component 31, and the audio output component 31 is located opposite to the audio output port 13, so that a data line connected to the external player 30 can be connected to the audio output component 31 through the audio output port 13.

The external player 30 may be an earphone and an external speaker, for example, as shown in fig. 7, the number of the audio output ports 13 is two, one of the audio output ports 13 is used for inserting the earphone, and the other audio output port 13 is used for inserting the external speaker.

For example, in a personal karaoke scenario, a karaoke artist may connect headphones through the audio output component 31. For another example, in the outdoor karaoke scene or in the relatively spacious indoor karaoke scene, the decibel of the built-in speaker 32 of the audio component 3 of the audio host is not enough, and the karaoke player can connect with the external audio through the audio output component 31 to enhance the playing effect.

In some examples, the audio host may further include a storage unit, and the storage unit may be configured to store the above-mentioned correspondence between the key identifiers of the sound effect keyboard 8 and the sound effect signals, and may also be configured to store accompaniment data, song data, and the like. In this embodiment, the specific content stored in the storage component is not limited, and can be flexibly selected according to the actual situation. Of course, the accompaniment data and song data may be acquired from the server through the smart device 20.

As described above, the audio host needs to be used with the smart device, and the audio host establishes a communication connection with the smart device through the smart device connection component 5.

In one example, the audio host and the smart device 20 may be wirelessly connected, for example, via a bluetooth connection between the audio host and the smart device, and correspondingly, the smart device connection component 5 is a bluetooth component, and for example, via a Wi-Fi connection between the audio host and the smart device, and correspondingly, the smart device connection component 5 is a Wi-Fi component.

In other examples, the audio host and the smart device may also be connected by a wire, and correspondingly, a wire connection manner may be that the audio host and the smart device are connected by a data line, a data transmission port is provided at a position of the case wall of the case 1 corresponding to the smart device connection part 5, one end of the data line is connected to the smart device connection part 5 by passing through the data transmission port, and the other end of the data line is connected to the smart device 20, so as to implement a communication connection between the audio host and the smart device 20.

Another wired connection mode between the audio host and the smart device 20 may also be, as shown in fig. 7, the smart device connection component 5 includes a data transmission connector 51, the data transmission connector 51 has a columnar structure and protrudes out of a wall of the chassis 1, a size of the data transmission connector 51 is adapted to a size of a data transmission interface of the smart device 20, when the smart device 20 is seated on the audio host, the data transmission connector 51 of the smart device connection component 5 extends into the data transmission interface of the smart device 20, so as to implement a communication connection between the audio host and the smart device 20.

In order to implement that the audio host can be connected to the smart devices 20 with multiple operating systems, correspondingly, one implementation manner may be that the smart device connecting component 5 may be a universal connecting component adapted to the data transmission interface of the smart devices 20 with multiple operating systems, so that the audio host can establish communication connection with the smart devices with multiple operating systems, for example, can establish communication connection with the smart device with Android operating System, and can also establish communication connection with the smart device with iSO (apple mobile device operating System) operating System. Another implementation manner may be that the number of the smart device connecting components 5 is multiple, and each smart device connecting component 5 corresponds to a data transmission interface of a smart device of one operating system, so that the audio host can establish a communication connection with smart devices of multiple operating systems, for example, the number of the smart device connecting components 5 is two, one corresponds to a data transmission interface of a smart device of an Android operating system, and the other corresponds to a data transmission interface of a smart device of an iSO operating system.

Based on the above, when a K singer intends to use the audio host to perform K singing, the connection with the intelligent device can be established through the intelligent device connecting part 5, and at the moment, the intelligent device can be used as a song ordering machine. The K singer can open K song software on the intelligent device, select song and accompaniment and the like, and the accompaniment audio selected by the K singer can be transmitted to the mixing processing component 22 through the intelligent device connecting component 5 so as to be prepared for the mixing processing component 22 to carry out mixing integration processing.

Then, the K singer can select a sound effect mode on the sound effect keyboard 8, and after the sound effect unit 7 obtains the sound effect mode selected by the K singer, the sound effect mode selected by the K singer can be sent to the sound effect processing unit 21, so that the sound effect processing unit 21 performs sound effect processing on the received dry sound, and wet sound conforming to the sound effect mode is obtained.

Then, the K singer can connect the microphone 10 to the microphone connecting part 4, input audio to the microphone connecting part 4 through the microphone 10, and after the microphone connecting part 4 receives the dry sound input by the K singer, first convert the analog signal into a digital signal and send it to the sound effect processing part 21. After receiving the dry sound, the sound processing section 21 performs sound processing based on the sound mode selected by the K singer to obtain a wet sound, and sends the wet sound to the mixing processing section 22. After receiving the wet sound, the mixing processing section 22 may perform mixing processing based on the accompaniment selected by the K singer to obtain mixed audio, and send the mixed audio to the sound section 3. The audio processing unit 33 of the audio component 3 receives the mixed audio, performs digital-to-analog conversion, converts the digital signal into an analog signal, transmits the analog signal to the power amplifier 34 for amplification, and transmits the analog signal to the built-in speaker 32, and the analog signal is played by the built-in speaker 32.

Therefore, the audio host and the intelligent device are matched together for use, the audio host performs audio processing, such as sound effect processing and sound mixing processing, the intelligent device 20 serves as a song ordering machine for a user to perform song ordering operation, interacts with a background server and the like, and the intelligent device 20 can also serve as a display for the user to watch display pictures.

Then, this K song system that audio frequency host computer and smart machine 20 constitute, with the smart machine that has K song function, because the audio frequency host computer mainly carries out audio processing, and the smart machine that has K song function mainly carries out communication processing, then, this audio frequency host computer possesses quick audio frequency processing effect, then the speed that the audio frequency host computer carried out audio frequency processing is faster, and audio frequency processing speed is fast, the time that the data after the audio frequency processing returned to the user ear just can shorten, so the ear returns the delay little, thereby promote user experience of using.

With the karaoke all-in-one machine that possesses song-ordering and karaoke function, the audio host computer need not to select the song to handle, need not to carry out karaoke image display and handle, and need not to carry out interactive processing etc. with the server, the audio chip of this audio host computer mainly is used for carrying out audio processing, so can accelerate in audio processing speed, in case audio processing speed accelerates, the time that data after so audio processing returned to the user ear will shorten, and then the ear returns and postpones for a short time, thereby promote user experience.

In addition, the audio host does not need to perform song selection processing, K song screen display processing, interactive processing with a server and the like, so that the audio host does not need to comprise components for performing the processing, and once the components are reduced, the cost of the audio host can be reduced.

As can be seen from the above, the smart device 20 connected to the audio host can be used as both a song requesting device and a display, and in order to further improve the user experience, correspondingly, as shown in fig. 8, the audio host further includes a display connection component 6, the display connection component 6 is located in the chassis 1, and the display connection component 6 is electrically connected to the smart device connection component 5, so that the smart device 20 outputs video data to the display 40; the display connection section 6 is configured to establish a communication connection relationship with the display 40 so that the display 40 displays a display screen output by the smart device 20.

The display may be a television, a projector, or the like, and is used to display a display screen output by the smart device 20.

In one example, the connection between the display 40 and the audio host may be a wireless connection, for example, a bluetooth connection between the display and the audio host, and correspondingly, the display connection component 6 may be a bluetooth component, and for example, a Wi-Fi connection between the display and the audio host, and correspondingly, the display connection component 6 may be a Wi-Fi component.

In other examples, the display 40 and the audio host may be connected by a wire, and accordingly, the display connection part 6 is specifically configured to establish a communication connection relationship with the display 40 by a data line, and in an implementation structure, the display connection part 6 may be an interface part, and is located in the chassis 1, as shown in fig. 9, a video transmission port 14 is provided on a wall of the chassis 1; the display connecting part 6 is positioned opposite to the video transmission port 14 so that a data line connected to the display 40 can be connected to the display connecting part 6 through the video transmission port 14.
