Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
Before introducing the vehicle-mounted karaoke device, the vehicle-mounted karaoke method and the vehicle provided by the disclosure, application scenes related to various embodiments of the disclosure are first introduced. The application scenario may include a vehicle provided with a vehicle-mounted K song device, which may be, for example, an automobile, but may also be applicable to other types of motor vehicles or non-motor vehicles, where the vehicle-mounted K song device includes a sound collector, a processor, and a player. The processor (for example, gao Tongxiao dragon processor chip) can customize according to specific vehicle model and hardware carrying environment to realize different functions, can realize more complex software function logic, and adapt to mobile phone function logic from a hardware virtual layer to an application framework layer depth, namely, the processor can support application programs of a plurality of development platforms, and the sound collector can be an FM (English: frequency Modulation, chinese: frequency modulation) microphone, a USB (English: universal Serial Bus, chinese: universal serial bus) microphone, a Bluetooth (English: bluetooth) microphone or an AUX (English: auxiliary, chinese: audio input interface) microphone.
Fig. 1 is a block diagram illustrating an in-vehicle K song apparatus according to an exemplary embodiment. As shown in fig. 1, for application to a vehicle, the apparatus 100 includes: sound collector 101, processor 102 and player 103.
When the processor 102 executes the K song function, the processor 102 is configured to send a first control instruction to the player 103, where the first control instruction includes a cut-source message and a mix-up message, where the cut-source message is used to instruct the input of the player 103 to be switched to the target input source, and the mix-up message is used to instruct the player 103 to perform mixing.
The sound collector 101 is used to send a speech signal to the player 103.
The processor 102 is further configured to send a preset multimedia signal to the player 103.
By way of example, the sound collector 101 may be connected to the player 103 via a wire harness, or may be connected to the player 103 via wireless communication (e.g., via a bluetooth connection or FM connection), and the processor 102 is connected to the player 103. When a user performs a K song, the processor 102 opens the K song application (for example, the user may click on an icon of the K song application through a central control screen of the vehicle), executes a K song function, and sends a first control instruction to the player 103. The sound collector 101 (which may be, for example, a microphone or the like) collects sound uttered by a user to acquire a voice signal, and transmits the voice signal to the player 103. Meanwhile, the processor 102 sends a preset multimedia signal to the player 103, where the preset multimedia signal is a multimedia signal pre-stored in the processor 102, and may be a piece of audio pre-set in the processor 102 according to specific requirements (such as name of accompaniment and volume of accompaniment) of a user when the processor 102 runs a K song application. When the processor 102 executes the singing function (i.e. executes the singing application), the first control instruction may include a cut-source packet and a mix packet, where the cut-source packet is used to instruct the input of the player 103 to be switched to the target input source, i.e. the player 103 will switch the input signal to the target input source indicated in the cut-source packet, and the mix packet is used to instruct the player 103 to mix the multiple input signals according to the parameters indicated in the mix packet.
The player 103 is configured to mix the voice signal and the multimedia signal according to the first control instruction, so as to obtain a play signal, and play the play signal.
For example, after receiving the first control instruction, the player 103 filters the cut-source packet, does not perform the step of switching the input signal of the player 103, mixes the voice signal with the multimedia signal according to the mixed packet (if the cut-source packet is not filtered, the player 103 can only play the multimedia signal, but cannot mix the voice signal with the multimedia signal to obtain the play signal), so as to obtain the play signal (i.e. the audio containing the voice signal and the multimedia signal), and plays the play signal, thereby implementing the K song function. When the processor 102 performs other functions (e.g., the user turns on a bluetooth phone, turns on a navigation application, turns on a video playing application, or selects an option to play only accompaniment on a K song application), other control instructions may be sent, where the other control instructions may include only a cut-source message, so that the player 103 plays a multimedia signal sent by a target input source indicated in the cut-source message (when the option to play only accompaniment is selected on the K song application, the target input source indicated in the cut-source message included in the other control instructions sent is a pre-selected accompaniment in the K song application).
It should be noted that, the connection manner between the sound collector 101 and the player 103 shown in fig. 1 is an example of a specific embodiment in the disclosure, the sound collector 101 and the player 103 may be connected by a wire harness, or may be connected by a wireless communication manner, and the connection manner between the sound collector 101 and the player 103 in the disclosure is not limited specifically.
To sum up, the vehicle-mounted K song device in the present disclosure includes: when the processor executes the K song function, a first control instruction is sent to the player through the processor, the first control instruction comprises a source cutting message and a sound mixing message, the source cutting message is used for indicating that the input of the player is switched to a target input source, the sound mixing message is used for indicating the player to carry out mixing, a voice signal is sent to the player through the sound collector, a preset multimedia signal is sent to the player through the processor, finally the voice signal and the multimedia signal are mixed through the player according to the first control instruction, and the playing signal is obtained and played. The method and the device can control the player to simultaneously receive the voice signal and the multimedia signal and mix the voice signal and the multimedia signal, so that the vehicle-mounted K song is realized, the K song application applicable to different vehicle types does not need to be customized additionally, and the user experience is improved.
Fig. 2 is a block diagram of another vehicle-mounted K song apparatus according to an exemplary embodiment. As shown in fig. 2, the apparatus 100 further includes a demodulator 104.
The sound collector 101 is further configured to modulate the collected sound to obtain a modulated signal, and send the modulated signal to the demodulator 104.
The demodulator 104 is configured to demodulate the modulated signal to obtain a voice signal, and transmit the voice signal to the player 103.
For example, when the sound collector 101 processes the collected sound through a preset modulation scheme, the apparatus 100 may further include a demodulator 104, and the demodulator 104 may be disposed between the sound collector 101 and the player 103. The sound collector 101 establishes a wireless connection with the demodulator 104 by means of analog modulation, and the demodulator 104 is connected with the player 103. The sound collector 101 may include a microphone and a modulation module, where the sound collector 101 collects sound sent by a user through the microphone, sends the collected sound to the modulation module, and modulates the collected sound by the modulation module according to a preset modulation mode to obtain a modulated signal, and sends the modulated signal to the demodulator 104, where the modulation mode may be any analog modulation mode, for example, may include: FM, AM (English: amplitude Modulation, chinese: amplitude modulation) or SSB (English: single Side Band, chinese: single Side Band modulation), etc. When the demodulator 104 receives the modulated signal, the modulated signal is demodulated by the demodulator 104 in a demodulation manner agreed with the sound collector 101 to obtain a voice signal, and the voice signal is transmitted to the player 103. The demodulation scheme is a demodulation scheme corresponding to the modulation scheme in the sound collector 101, and may be, for example, FM demodulation, AM demodulation, SSB demodulation, or the like.
Optionally, the demodulator 104 is further configured to adjust the demodulation frequency to a preset frequency, where the demodulation frequency is a frequency at which the demodulator 104 demodulates the modulated signal, before the processor 102 performs the K song function.
The sound collector 101 is further configured to adjust a modulation frequency to a preset frequency, so that the sound collector 101 is connected to the demodulator 104, where the modulation frequency is a frequency of the sound collected by the sound collector 101.
For example, before the sound collector 101 transmits a voice signal to the player 103 by means of analog modulation, the sound collector 101 needs to establish a wireless connection with the demodulator 104 by means of analog modulation. The connection between the sound collector 101 and the demodulator 104 may be established by an analog modulation method, in which the demodulation frequency is first adjusted to a preset frequency by the demodulator 104, then the modulation frequency is adjusted to the preset frequency by the sound collector 101, and when the demodulation frequency of the demodulator 104 and the modulation frequency of the sound collector 101 are both adjusted to the preset frequency, the connection between the sound collector 101 and the demodulator 104 is successful by the analog modulation method. For example, the sound collector 101 may be an FM microphone, the demodulator 104 may be a radio on a vehicle, and before using the K song function, the user turns on the radio and adjusts the frequency of the radio to an idle frequency (the idle frequency is a frequency occupied by no broadcast signal), then turns on the FM microphone, and adjusts the frequency of the FM microphone to be the same as the frequency of the radio, where the FM microphone and the radio are successfully connected.
Optionally, the processor 102 is further configured to suspend sending the multimedia signal to the player 103 when receiving a preset interrupt signal, and send a second control instruction to the player 103, where the second control instruction includes a cut-source message.
The player 103 is further configured to pause playing the playing signal according to the second control instruction, and play the signal of the target input source indicated by the cut source message.
The processor 102 is further configured to send a multimedia signal to the player 103 when receiving a preset interrupt stop signal, and send a third control instruction to the player 103, where the third control instruction includes a mixing packet.
The player 103 is further configured to play the play signal according to the third control instruction.
For example, when the processor 102 receives a preset interrupt signal, the processor 102 pauses sending the multimedia signal to the player 103, and sends a second control instruction to the player 103, where the second control instruction includes a cut-source message, and the preset interrupt signal is used to instruct the processor 102 to pause the K song function, for example, the user actively pauses the K song during the K song process, or when the processor 102 needs to run other applications (such as a bluetooth phone, a navigation application, and a video playing application), the processor 102 receives the interrupt signal. The player 103 pauses playing signals according to the second control instruction (cut-source message), then switches the input of the player 103 to a target input source, and plays signals of the target input source indicated by the cut-source message, for example, a bluetooth phone call is in the process of K songs, the processor 102 receives a preset interrupt signal, pauses the K song function according to the preset interrupt signal, operates the bluetooth phone function, and sends the second control instruction to the player 103, the player 103 pauses playing signals according to the second control instruction, then switches the input of the player 103 to the bluetooth phone input source, and plays signals sent by the bluetooth phone input source (namely, call voice in the operation process of the bluetooth phone). When the processor 102 receives a preset interrupt stop signal (the preset interrupt stop signal is used for indicating the processor 102 to continue to perform the karaoke function), the multimedia signal is continuously sent to the player 103, a third control instruction is sent to the player 103, the third control instruction includes a mixing message, and the player 103 mixes the voice signal and the multimedia signal according to the third control instruction (mixing message) to obtain a playing signal, and the playing signal is played. For example, during the process of singing, as the user uses the navigation application, the processor 102 pauses the singing function, when the processor 102 detects that the user finishes using the navigation application, the processor 102 receives a preset interrupt stop signal, continues to send a multimedia signal to the player 103 according to the preset interrupt stop signal, sends a third control instruction to the player 103, and the player 103 mixes the voice signal and the multimedia signal according to the third control instruction to obtain a play signal, and plays the play signal, so as to continue singing.
It should be noted that, when the user finishes the K song or terminates the K song by operating other applications, the processor 102 will stop sending the multimedia signal to the player 103, and send the cut-source message to the player 103, and the player 103 stops playing the playing signal according to the cut-source message, and plays the signal of the target input source indicated by the cut-source message.
Optionally, the first control instruction further includes a play message, where the play message is used to indicate a play parameter of the player 103, and the play message includes at least one of a power amplifier parameter, an equalizer parameter, a tone, a timbre, or a loudness.
For example, in order to make the user obtain better karaoke experience, the first control instruction may further include a play packet, where the play packet is used to instruct play parameters of the player 103, and the play packet is processed by the player 103 according to a voice signal of the play packet Wen Duiyu to obtain better karaoke effect, for example, processing such as EQ (English: equalizer, chinese: equalizer) adjustment, sound changing processing, adding a sound special effect, changing a gain of a power amplifier, and the like may be performed on the voice signal. The play-out message includes at least one of a power amplifier parameter, an equalizer parameter, a tone, a timbre, or a loudness. The preset parameters may be preset in the processor 102 by the user before the user performs the singing, or may be set in the processor 102 in real time by the user during the singing according to specific requirements. For example, a K song gadget may be set in the processor 102 and opened synchronously when the processor 102 opens the K song application (the K song gadget may appear on the central control screen of the vehicle in the form of a suspension page, the user may drag the K song gadget and stay at any position on the central control screen of the vehicle, without affecting the use of the K song application by the user), during the K song process, if the output of the sound quality or the effect of the K song by the user is unsatisfactory, the power amplifier parameter, equalizer parameter, tone or loudness may be adjusted in real time by the K song gadget to adjust the K song effect, after the user adjustment is completed, the K song gadget sends the user-adjusted parameter to the processor 102, the processor 102 generates a play message according to the user-adjusted parameter sent by the K song gadget, and sends a first control instruction including the play message to the player 103, and when the K song is finished, the K song gadget is closed synchronously when the processor 102 closes the K song application.
Fig. 3 is a block diagram illustrating yet another vehicle-mounted K song apparatus according to an exemplary embodiment. As shown in fig. 3, the apparatus 100 further comprises an image collector 105.
When the processor 102 performs the karaoke function, the processor 102 is configured to send an on command to the image collector 105.
The image collector 105 is used for collecting image information after receiving the start instruction.
For example, when using the karaoke function, the user may need to capture images during the karaoke process (e.g., record karaoke video) in real time, and for this purpose, the apparatus 100 may further include an image capturing device 105, where the image capturing device 105 is connected to the processor 102, and the image capturing device 105 may be, for example, a camera or a video camera.
