Detailed Description
In order to make the present application better understood by those skilled in the art, the following description will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The method for regulating and controlling the stereo sound effect in the vehicle provided by the embodiment of the application can be implemented through computer equipment, wherein the computer equipment can be terminal equipment or a server, and the server can be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server for providing cloud computing service. The terminal equipment comprises, but is not limited to, mobile phones, computers, intelligent voice interaction equipment, intelligent household appliances, vehicle-mounted terminals and the like. The terminal device and the server may be directly or indirectly connected through wired or wireless communication, which is not limited in any way by the present application.
The following examples are provided to illustrate the invention:
fig. 1 is a flowchart of a method for adjusting and controlling stereo sound effects in a vehicle, which is provided by an embodiment of the present application, and is described by taking a terminal device as an example of the foregoing computer device, where the method is applied to a vehicle, and a first speaker, a second speaker and a vibration speaker are installed in the vehicle, and the vibration speaker is located between the first speaker and the second speaker, and the method includes S101-S104:
S101: acquiring an audio analog voltage signal of a first loudspeaker as a first voltage signal, and acquiring an audio analog voltage signal of a second loudspeaker as a second voltage signal;
the first loudspeaker and the second loudspeaker are loudspeakers which are installed in the vehicle and can be independently played, and in the process of the two loudspeakers being operated together, the stereo sound effect can be output for the interior of the vehicle, and the stereo sound effect output at the moment is a 3D sound effect. The vibration loudspeaker can provide vibration perception for a user on the basis of 3D sound effects, and 4D sound effects are built.
It should be noted that the present application is not limited in any way with respect to the types and numbers of the first speaker and the second speaker. For example, the first speaker may be a left speaker of the vehicle, and the second speaker may be a right speaker of the vehicle, wherein the left speaker may further include a front left speaker and a rear left speaker, and the right speaker may further include a front right speaker and a rear right speaker. As another example, the first speaker may also include a center position speaker, or the like.
In practical application, left speaker and the right speaker of vehicle can install in door department, and correspondingly, consider vibration speaker's purpose can provide vibration perception for the user on the basis of 3D audio, builds 4D audio, so can install vibration speaker in saddle department, when making vibration speaker be located between first speaker and the second speaker based on this, be favorable to improving user's vibration perception experience. It will be appreciated that vibration also produces sound waves, and thus a vibrating speaker may refer to a speaker that functions primarily as vibration, rather than a speaker that vibrates only without sound waves.
It can be seen that the tuning of the vibration speaker can change the 4D sound experience of the user. During actual regulation, the audio analog voltage signal of the first loudspeaker can be firstly obtained as a first voltage signal, and the audio analog voltage signal of the second loudspeaker can be obtained as a second voltage signal, so that subsequent regulation can be performed.
The audio signals in the vehicle are typically transmitted digitally, so that in one possible implementation the digital audio signals of the vehicle, including the digitized audio signals of the first and second speakers, may be received by a digital signal processing unit. Further, the digital audio signal is converted by the digital signal processing unit, the digital audio signal of the first speaker is converted into an analog signal, and then the audio analog voltage signal of the first speaker can be obtained, so that the first voltage signal is obtained, and similarly, the digital audio signal of the second speaker can be converted into an analog signal, and then the audio analog voltage signal of the second speaker can be obtained, so that the second voltage signal is obtained.
In practical applications, the digital audio signal of the vehicle may be an A2B signal, and the digital signal processing unit (DIGITAL SIGNAL Processor, DSP) performs conversion processing on the received A2B signal to output a first voltage signal and a second voltage signal. In specific implementation, the conversion process may include processing steps of amplitude processing, time delay processing, frequency shift processing, multichannel independent processing, audio mixing processing, basic operation, and the like, where a multichannel refers to a plurality of in-vehicle speakers (i.e., a first speaker and a second speaker) of the vehicle. After DSP processing, a multi-channel independent audio data stream, i.e. an audio analog voltage signal with independent channels, can be output.
S102: a voltage magnitude difference between the first voltage signal and the second voltage signal is determined.
After the first voltage signal and the second voltage signal are acquired, a voltage amplitude difference between the first voltage signal and the second voltage signal may be further determined. Since the vibration speaker is located between the first speaker and the second speaker, the voltage amplitude difference can reflect the distance of the sound source from the vibration speaker, and therefore, the vibration speaker can be regulated and controlled by the voltage amplitude difference.
In practical applications, the absolute value of the voltage difference between the first voltage signal and the second voltage signal may be determined as the voltage amplitude difference.
S103: a target output voltage of the vibration speaker is determined based on the voltage magnitude difference.
S104: and controlling the operation of the vibration loudspeaker according to the target output voltage.
When the voltage amplitude difference is utilized to regulate and control the vibration loudspeaker, the target output voltage of the vibration loudspeaker can be determined according to the voltage amplitude difference, and then the vibration loudspeaker is controlled to operate according to the target output voltage. During operation of the vibration speaker, vibrations may be generated to provide a user with a perception of the vibrations. Because the target output voltage and the voltage amplitude difference are in inverse proportion, based on the inverse proportion, the target output voltage of the vibration loudspeaker is higher as the sound source is closer to the vibration loudspeaker, the vibration effect is more obvious, and conversely, the vibration effect is weakened, so that richer three-dimensional sound effect perception can be provided for in-vehicle users, and the user experience is improved. For example, when the vibration speaker is installed at the seat, the user sits at the seat in the vehicle, and can experience different vibration sensations along with the distance between the sound source and the vehicle.
The vibration speaker is one of the in-vehicle speakers, and corresponds to an initial output voltage, which may be a default output voltage of the vibration speaker, for example, an output voltage allocated to the vibration speaker when an audio system of the vehicle is turned on for use. Because the initial output voltage cannot provide vibration sensing for the user, which varies with the distance of the sound source, in one possible implementation, the initial output voltage of the vibration speaker may be obtained first, and then the initial output voltage may be corrected according to the voltage amplitude difference, to obtain the target output voltage. Based on the method, the initial output voltage can be corrected by utilizing the voltage amplitude difference, so that the actual voltage output of the vibration loudspeaker can be conveniently regulated and controlled to be the target output voltage, and rich vibration perception is provided for a user.
For easy understanding, for the above embodiments, the embodiments of the present application further correspondingly provide a manner of determining the target output voltage, specifically, the target output voltage may be determined by the following formula:
Wherein U T is a target output voltage, U t is an initial output voltage, Δa is a voltage amplitude difference, a 1 is a first voltage signal, a 2 is a second voltage signal, Δa= |a 1-A2 |.
For example, when the first speaker is a left speaker and the second speaker is a right speaker, a 1 may be a voltage amplitude a L,A2 of the left channel obtained by the DSP converting the A2B signal, and a voltage amplitude a R of the right channel obtained by the DSP converting the A2B signal. Based on this, as the voltage amplitude difference of the left and right side channels is larger, the target output voltage allocated to the vibration speaker is smaller, and conversely, larger.
In practical application, the first speaker can be controlled to operate according to the first voltage signal, the second speaker can be controlled to operate according to the second voltage signal, and in the operation process of the first speaker and the second speaker, the stereo sound effect can be output to the vehicle through the first speaker and the second speaker, and the stereo sound effect is a 3D sound effect. Because in this process, according to the operation of target output voltage control vibration speaker, and vibration speaker can produce the vibration in operation in-process, so can adjust 3D audio, because increased vibration perception, so the user can experience 4D audio, and the intensity of vibration perception that user experienced can change along with the sound source distance change to some extent, from this, can provide richer three-dimensional audio perception for the user, improves user experience.
In practical applications, when the first speaker, the second speaker and the vibration speaker are controlled to operate, the first voltage signal, the second voltage signal and the target output voltage can be processed through the DSP, and the processed signals are output to a microprocessor (Microcontroller Unit, MCU) of the vehicle, and then the MCU transmits the received signals to a power amplifying unit of the vehicle, and the AMP amplifies the received signals and then drives the first speaker and the second speaker to sound, and drives the vibration speaker to vibrate.
As can be seen from the above technical solution, for a vehicle mounted with a first speaker, a second speaker and a vibration speaker, firstly an audio analog voltage signal of the first speaker is obtained as a first voltage signal and an audio analog voltage signal of the second speaker is obtained as a second voltage signal, and a voltage amplitude difference between the first voltage signal and the second voltage signal is determined. Since the vibration speaker is located between the first speaker and the second speaker, the voltage amplitude difference can reflect the distance of the sound source from the vibration speaker, and thus, the target output voltage of the vibration speaker can be determined according to the voltage amplitude difference, and the operation of the vibration speaker can be controlled according to the target output voltage. The target output voltage and the voltage amplitude difference are in inverse proportion, based on the inverse proportion, the target output voltage of the vibration loudspeaker is higher as the sound source is closer to the vibration loudspeaker, the vibration effect is more obvious, and conversely, the vibration effect is weakened, so that richer three-dimensional sound effect perception can be provided for in-vehicle users, and the user experience is improved.
In order to facilitate understanding, the embodiment of the application provides a three-dimensional sound effect regulation scene schematic diagram in the in-vehicle video observation process, and particularly, the schematic diagram can be shown in fig. 2. Assuming that a user drives a car from right to left in a movie watched by the user, taking a first loudspeaker as a left loudspeaker and a second loudspeaker as a right loudspeaker as examples, and when the car is still on the right side, the right side volume is larger and the left side volume is smaller; when the automobile runs right ahead, the sound of the right and left speakers is loud; when the automobile runs to the left, the left sound volume is larger, and the right sound volume is smaller. Without the cooperation of vibration speakers, this is a typical scene of left and right stereo (3D sound effect), and through the change of the sound sizes of the left and right speakers, the user can feel the stereo 3D feeling that the car gradually passes through in the film. After the regulating and controlling method is adopted, the voltage amplitude difference of the left speaker and the right speaker can be analyzed in real time, the output voltage of the vibration speaker is controlled to be the target output voltage, the distance from a sound source to the vibration speaker (taking the vibration speaker as the position of a user as an example) is changed from small to large along with the driving of a car from right to left, and accordingly, the target output voltage can be changed from small to large and from large to small, the vibration effect of the vibration speaker is changed from weak to strong and from strong to weak, so that the user can experience continuously changing vibration perception in the film watching process, and the user experience is improved.
Since the larger the output voltage of the vibration speaker, the larger the amplitude and the stronger the vibration effect, it is considered that the right sound volume is larger, the left sound volume is smaller, and the amplitude of the vibration speaker is smaller when the vehicle is on the right side, so that the user can feel that the vehicle is on the side farther from the person (the far right side). When the vehicle is traveling right in front, the right and left speakers are loud, the vibration speaker has a large amplitude, and the user feels that the vehicle is in a position closer to the person (right in front). When the car runs to the left, the left sound volume is larger, the right sound volume is smaller, the amplitude of the vibration loudspeaker is small, and the user feels that the car is at a side far away from the person (far to the left).
It should be noted that the above application scenario is only an example, and may be applied to other scenarios. For example, taking the example that the first speaker and the second speaker include 7.1 channels, assuming that birds in a film fly around the crown in the sky, each speaker can achieve such a surround sound effect by controlling the volume level. The vibration loudspeaker still determines the intensity of the amplitude according to the voltage amplitude difference of each loudspeaker. For example, when a bird spirals directly above the crown, the voltage amplitude difference for each speaker should be minimal, the vibration speaker amplitude should be strong, and when a bird flies off the crown, there is a beginning difference in the voltage amplitude for each speaker, the vibration speaker amplitude should be weak. Thus, the auxiliary enhancement of the stereo by the vibration loudspeaker can be realized. The 7.1 sound channel is a stereo playing form formed by adding 2 speakers on the left side and the right side of a 5.1 sound channel formed by a front left speaker, a rear left speaker, a front right speaker, a rear right speaker and a central position speaker in the vehicle.
In practical application, the embodiment of the application also provides an in-vehicle stereo sound control system, the structure diagram of which can be shown in fig. 3, and the in-vehicle stereo sound control system can comprise a power module, a digital signal processing unit DSP, a microprocessor MCU, a power amplifying unit and in-vehicle speakers, in particular:
The power supply is connected to the power supply module, the power supply module can supply power for the DSP, the MCU and the power amplifying unit, and the power supply module can perform actions such as voltage reduction operation, voltage stabilization power supply and the like through internal chip processing. Generally, after receiving the A2B signal, the DSP may perform conversion processing (such as amplitude processing, time delay processing, frequency shift processing, multi-channel independent processing, audio mixing processing, basic operation, etc.) on the A2B signal, so as to output audio analog voltage signals of other speakers (i.e., the first speaker and the second speaker) in the vehicle, and analyze and output a target output voltage of the vibration speaker based on the voltage amplitude difference. In practical application, the DSP may send the processed signal to the MCU through data transmission, and then the MCU may send the processed signal to the power amplifying unit through data transmission, and after amplifying the signal by a power amplifying chip (AMP) in the power amplifying unit, the vehicle speaker (including the first speaker, the second speaker and the vibration speaker) is driven to operate. The first speaker and the second speaker may include a front left speaker, a rear left speaker, a front right speaker, a rear right speaker, and a center speaker, i.e., fig. 3 is exemplified as 5.1 channels.
The MCU is a core processor chip of the in-vehicle stereo sound control system, and CAN load signal interaction of the whole vehicle CAN network, quality interaction of all chips in the in-vehicle stereo sound control system, logic operation, event processing and the like. The MCU CAN receive external instructions according to the CAN network of the vehicle, and the actions required by the external instructions are realized through the interaction of the instructions and information of chips in the system. The power amplifying unit may include a plurality of power amplifying chips, which may amplify the received audio signal and then output the amplified signal to drive the speakers in the respective vehicles to operate. The in-car speakers may include a plurality of speakers that are independently played, and fig. 3 illustrates 5.1 channels, and these in-car speakers may be distributed at appropriate positions in the car for playing the amplified signals output by the power amplification chip.
Correspondingly, the embodiment of the application also provides an in-vehicle stereo sound effect regulation and control flow, and the flow can be specifically shown in fig. 4. Fig. 4 shows a schematic flow chart of three-dimensional sound effect regulation in a vehicle, taking a first speaker and a second speaker as a left speaker and a right speaker respectively as examples, the DSP receives an A2B signal, and further the DSP analyzes the difference of the amplitudes of the left channel signal and the right channel signal in the A2B signal (i.e. the aforementioned voltage amplitude difference) through an operation module. The larger the amplitude difference, the larger the output signal (i.e., the larger the target output voltage) that the DSP calculates to be distributed to the channels of the vibration speaker, and vice versa. The DSP transmits the calculated output values of all channels to the microprocessor, the microprocessor transmits the received DSP signals to the power amplifying unit, and the power amplifying unit amplifies the signals and drives all the loudspeakers to operate, specifically, the power amplifying unit drives the left and right loudspeakers to sound and drives the vibration loudspeakers to vibrate.
It is to be understood that this corresponds substantially to the method embodiments, so that reference is made to the partial description of the method embodiments for relevant reasons.
