Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
The in-vehicle sound control method provided by the embodiment can be applied to the application environment shown in fig. 1, in which the client communicates with the server. The client includes, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices. The server side can be implemented by an independent server or a server cluster formed by a plurality of servers.
In an embodiment, as shown in fig. 2, an in-vehicle sound control method is provided, which is described by taking the method applied to the server side in fig. 1 as an example, and includes the following steps S10 to S40.
And S10, when the target sound is output, determining a target sound zone through a detection device, wherein the target sound zone is associated with a target loudspeaker.
Understandably, the target sound refers to a sound transmitted to a target occupant (including a driver) in a target seat, and it can also be understood that the target sound is a sound that the target occupant in the target seat wants to hear. The target sounds include, but are not limited to, navigation sounds, electric voices, human voices, warning sounds, musical tones, and audiovisual sounds. The target sound of each seat can be automatically identified by the vehicle-mounted system, and the target sound can also be set by the passengers. As shown in fig. 3, fig. 3 is a schematic plan view of an example car audio arrangement position on a vehicle. In one example, the target sound may refer to the sound delivered to the driver, which may be played out by speakers 02-FL (FL representing the front left position).
The detection device may be a camera 01 or other device that can determine the position of the occupant's head. The head portion of the target occupant may be set as a target zone to secure the auditory effect of the target occupant. Each seat may be provided with a dedicated speaker 03 or set of speakers for enhancing the auditory perception of the occupant in that seat. The target loudspeaker is the special loudspeaker 03 of the seat where the target sound zone is located. Thus, there is an association between the target sound zone and the target speaker.
And S20, acquiring interference audio data of the target sound zone.
Understandably, the interference audio data is used for audio data that emits an interference sound. Here, the disturbing sound may refer to a sound generated from a range other than the target range. That is, the disturbing sound refers to a sound different from the target sound. For example, when a current vehicle is playing a musical tone, a pilot tone (target sound) needs to be played (i.e., output) in a target musical section, the musical tone is an interfering sound, and audio data for generating the musical tone is interfering audio data.
And S30, synthesizing anti-interference audio data of the target sound zone according to the characteristics of the target loudspeaker and the interference audio data.
Understandably, the characteristics of the target speaker include sound characteristics and/or position characteristics. Here, the sound characteristic of the target speaker may refer to sound quality difference data between the target speaker and other speakers in the vehicle. Different loudspeakers generally have different sound quality and loudness. Through the sound characteristic, the anti-interference sound emitted by the target loudspeaker can be matched with the interference sound, and the interference of the interference sound on the target sound is further reduced. The position characteristic refers to a position of the target speaker. The sound amplitude of the anti-interference audio data can be adjusted according to the distance between the target loudspeaker and the target sound zone. If the distance increases, the sound amplitude of the anti-interference audio data increases, and if the distance decreases, the sound amplitude of the anti-interference audio data decreases. The interference audio data is subjected to anti-phase processing to obtain corresponding anti-phase audio data, and then the anti-interference audio data can be obtained by adjusting the anti-phase audio data according to the characteristics of the target loudspeaker.
And S40, inputting the anti-interference audio data into the target loudspeaker so as to enable the target loudspeaker to generate anti-interference sound.
Understandably, the anti-interference audio data is input into the target loudspeaker, so that the target loudspeaker can generate anti-interference sound, the anti-interference sound and the interference sound are mutually offset, the definition of the target sound can be improved, and the hearing sense of a target passenger to the target sound is improved.
In steps S10 to S40, when the target sound is output, a target sound zone is determined by the detection device, the target sound zone is associated with the target speaker to accurately locate the target sound zone, and the target sound zone changes with time if the head position of the target occupant corresponding to the target sound zone changes. And acquiring interference audio data of the target sound zone, wherein the interference audio data refers to audio data input to any one or more loudspeakers except the target loudspeaker, and the interference audio data can be music audio data, so that a microphone for monitoring noise in the vehicle does not need to be additionally added, and the upgrading cost of the sound system of the vehicle can be reduced. And synthesizing the anti-interference audio data of the target sound zone according to the characteristics of the target loudspeaker and the interference audio data to obtain anti-interference audio data for canceling interference sound, wherein the anti-interference audio data changes along with the change of the position of the target sound zone. Will anti-interference audio data input the target speaker, so that the target speaker produces anti-interference sound, here, through making anti-interference sound and interference sound offset each other, can improve the definition of target sound, improves car audio system's sound and experiences.
Optionally, the in-vehicle sound control method further includes:
s11, when the target sound is output, inputting audio data corresponding to the target sound into the target loudspeaker so as to enhance the target sound.
Understandably, when the target sound is output, the audio data corresponding to the target sound can be input into the target loudspeaker, so that the target loudspeaker emits the target sound, thereby further enhancing the target sound, improving the recognition degree of the target passenger to the target sound, and reducing the interference of the interference sound to the target sound.
Optionally, the detection device is a shooting device 01;
step S10, namely, determining a target sound zone by a detection device when outputting a target sound, wherein the target sound zone is associated with a target loudspeaker, and the step includes:
s101, detecting the head position of a target passenger through the shooting device 01;
and S102, setting the head part as the target sound zone.
Understandably, as shown in fig. 3, the detection device may be provided at the camera 01 of the front of the automobile. An image of a target occupant in the vehicle is captured by the capturing device 01, the head position of the target occupant is detected from the image, and then the head position is set as a target sound zone. In some examples, the target range may be represented by the distance of the head position from the various sounds in the vehicle. Specifically, the distance between the head position and the left front speaker is x 1 The distance between the head position and the right front sound is x 2 The head regionThe distance between the left rear sound box and the left rear sound box is x 3 The distance between the head position and the right rear sound box is x 1 Then the target interval may represent [ x ] 1 、x 2 、x 3 、x 4 ]。
Optionally, a plurality of speakers are arranged on the vehicle, and the target speaker is the speaker or the group of speakers with the smallest distance to the target sound zone.
Understandably, the target speaker is the one or group of speakers that are the smallest distance from the target sound zone. Because the distance from the target sound zone is minimum, the anti-interference effect of the anti-interference sound generated by the target loudspeaker to the target sound zone is best, and the influence on other sound zones is less. In some examples, the pilot tone played in the driver seat and the tone played in the co-driver seat may then play a first anti-interference sound for canceling the tone at a first target speaker in the driver seat and a second anti-interference sound for canceling the pilot tone at a second target speaker in the co-driver seat, while enhancing the listening experience in the driver seat and the co-driver.
In some cases, a set of speakers may also be provided around the target sound zone in order to better achieve the sound immunity effect. For example, the set of speakers may be provided in a door, a roof, etc. adjacent to the seat, in addition to the speakers provided in the headrest or the seat.
Optionally, the target speaker is disposed at an upper portion of a target seat corresponding to the target sound zone; and/or the presence of a gas in the atmosphere,
the target speaker is provided on a headrest corresponding to the target sound zone.
Understandably, in order to better eliminate the interfering sound while reducing interference with other sound zones, the target speaker should be located as close as possible to the head of the occupant, such as the upper portion of the target seat corresponding to the target sound zone, or a headrest provided on the target seat (i.e., a headrest corresponding to the target sound zone).
Optionally, the characteristics of the target speaker include sound characteristics and/or position characteristics;
step S30, namely, the synthesizing the anti-interference audio data of the target sound zone according to the characteristics of the target speaker and the interference audio data includes:
s301, performing anti-phase processing on the interference audio data to obtain anti-phase audio data.
S302, adjusting the anti-phase audio data according to the position of the target sound zone and the characteristics of the target loudspeaker to generate the anti-interference audio data.
Understandably, the anti-interference audio data can be obtained by performing anti-phase processing on the interference audio data and then adjusting the anti-phase audio data according to the characteristics of the target loudspeaker. In some cases, the time delay of the tamper resistant audio data may be set according to the location of the target soundzone. In other cases, the reverberation characteristics of the target sound zone can be considered, and the anti-interference audio data can be set in combination with the reverberation characteristics.
Wherein the characteristics of the target speaker comprise sound characteristics and/or position characteristics. Here, the sound characteristic of the target speaker may refer to sound quality difference data between the target speaker and other speakers in the vehicle. Different loudspeakers generally have different sound quality and loudness. Through the sound characteristic, the anti-interference sound emitted by the target loudspeaker can be matched with the interference sound, and the interference of the interference sound on the target sound is further reduced. The position characteristic refers to a position of the target speaker. The sound amplitude of the anti-interference audio data can be adjusted according to the distance between the target loudspeaker and the target sound zone. If the distance increases, the sound amplitude of the anti-interference audio data increases, and if the distance decreases, the sound amplitude of the anti-interference audio data decreases.
Optionally, the interference audio data is audio data input to any one or more speakers other than the target speaker.
Understandably, the interfering audio data may be audio data input to any one or more speakers other than the target speaker. The number of the interference audio data may be one or more. For example, if the speaker of the front left seat needs to play a pilot sound, the speaker of the front right seat needs to play a musical sound, and the speaker of the rear left seat needs to play a movie sound, the pilot sound is a target sound, and the musical sound and the movie sound are interfering sounds for the target sound zone of the front left seat. Thus, the audio data for generating musical tones and the audio data for generating electric audio-visual data both belong to the disturbance audio data.
Optionally, in step S20, after the obtaining of the interference audio data of the target sound zone, the method further includes:
s31, acquiring position information of an interference loudspeaker, wherein the interference loudspeaker is used for converting the interference audio data into interference sound;
and S32, synthesizing the anti-interference audio data according to the position information of the interference loudspeaker and the interference audio data.
Understandably, when the interference audio data are synthesized, the position information of the interference loudspeaker can be obtained, the anti-phase processing is carried out on the interference audio data, the corresponding anti-phase audio data can be obtained, and then the anti-phase audio data are adjusted according to the position information of the interference loudspeaker. The disturbing speaker refers to a speaker that converts disturbing audio data into disturbing sound. And adjusting the time delay and amplitude involved when the anti-phase audio data is adjusted according to the position information of the interference loudspeaker. As shown in fig. 3, if the speakers 02-FL (front left) play the target sound and the speakers 02-FR (front right) play the interfering sound, it is necessary to cancel the interfering sound played by the speakers 02-FR. The disturbing sound has a frequency f and an amplitude y 1 dB, the target speaker of the headrest (corresponding to the speaker 02-FL) arranged on the driving position needs to be delayed by z seconds (i.e. delay) to emit the signal with frequency f and amplitude y 2 dB of interference-free sound (opposite in phase to the interference sound). Wherein, the delay time is as follows: z = x 2 /c，x 2 Distance (x) of speaker 02-FR from target sound zone 2 Obtained when the head position of the driver is determined by the camera 0101), c is the sound speed; amplitude y of anti-interference sound 2 Comprises the following steps: y is 2 ＝y 1 *α*x 2 Where α is the sound attenuation coefficient.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
