Detailed Description
Hereinafter, example embodiments according to the present disclosure will be described in detail with reference to the accompanying drawings. It is to be understood that the described embodiments are merely a subset of the embodiments of the present disclosure and not all embodiments of the present disclosure, with the understanding that the present disclosure is not limited to the example embodiments described herein.
Summary of the application
It is known that it is very common for a driver or a passenger to play various sound source information by using a sound in the vehicle while riding the vehicle. However, in different specific scenarios, the requirements of the driver or passenger for sound playing are different.
For example, the sound source information may be specifically music, broadcast, and other audio for "entertaining" passengers, and such sound source information may be collectively referred to as first type sound source information in the present disclosure. For the first type of sound source information, it is common that all passengers need to listen, and it is not desirable that ambient noise while the vehicle is traveling interferes with listening; however, it is undesirable for the first type of sound source information to interfere when the passenger is talking or making a call. This is the actual demand of the driver and passengers in a particular scenario.
The sound source information may specifically be navigation voice, or other various audio dedicated to prompt and warn the driver. Such sound source information may be collectively referred to as second type sound source information in the present disclosure. For the second type of sound source information, only the driver often needs to listen to the information, and it is not desirable that any type of noise information interferes with it.
As can be seen, the listening needs of drivers and passengers for sound source information are very diverse. However, in the prior art, the sound playing control can be performed only by increasing or decreasing the playing volume, which is not only single in form, but also cannot automatically judge the requirements of the driver or the passengers, thereby automatically controlling the playing of the sound in the vehicle.
Exemplary method
Fig. 1 is a schematic flowchart of an in-vehicle sound playing method according to an exemplary embodiment of the present application. The present embodiment can be applied to an electronic device, as shown in fig. 1, the present embodiment includes the following steps:
In the embodiment, the position of the passenger can be determined by a pressure sensor on the vehicle seat, or the position of the passenger can be determined by shooting and face recognition through a camera built in the vehicle. Of course, other technical means can be selected to determine the position of the passenger according to the requirement, which is not limited herein, and any technical means capable of achieving similar effects can be combined in the overall technical solution of the embodiment.
The first sound playing parameter is a playing parameter of each sound in the vehicle, for example, the first sound playing parameter may be a playing volume, a frequency range, and the like of each sound. The first sound playing parameter may be determined by a first soundstage center position. The sound stage center position may refer to a position in space where sound wave energy is most concentrated when sound is played. The first sound stage center position can be considered as a "best listening position" for determining sound source information at the time of playback. The first soundstage center position will be determined based on the passenger position. The 'best listening position' of the sound source information during playing is determined by the first sound field center position, so that each passenger can obtain ideal sound playing effect.
For example, for the first type of sound source information, since all passengers need to listen, in order to ensure that each passenger has a good listening effect, the first sound stage center position may be determined as the geometric center position of all passengers, or may be adaptively set according to the habits of the passengers. According to the passenger positions, the distribution situation of the passenger positions can be determined, and the specific corresponding relation between the distribution situation of the passenger positions and the center position of the first sound field can be shown by referring to the following table:
| distribution of passenger positions | Center position of first sound field |
| Only the driver | Driver face center |
| Driver + passenger in the passenger seat | Between driver and passenger in the passenger seat |
| Driver +1 rear passenger | Intermediate the driver and the rear passenger |
| Driver + multiple rear passengers | Rear row middle |
| The member of the whole population | Geometric center of space in vehicle |
As shown in fig. 2, i.e. the corresponding passenger position distribution is specifically "driver + passenger in the passenger seat", the first soundstage center position is located at point X in the figure, i.e. in the middle between the driver and the passenger in the passenger seat.
For the second type of sound source information described above, only the driver generally needs to listen to it, while other passengers do not. The first soundstage center position can be directly determined to be in the vicinity of the driver.
And 102, playing sound source information according to the first sound playing parameter.
The sound source information may specifically refer to a sound source file or an audio file that needs to be played. The sound source file can be an audio file stored locally, or a sound source file received and played through a network or an FM radio. After the first sound playing parameter is determined, the sound source information can be played according to the setting of the first sound playing parameter, so that each passenger can obtain an ideal sound playing effect. To play the sound source information according to the first sound stage center position, referring to fig. 2, the following specific implementation may be referred to:
generally, sound in the vehicle interior is distributed in various directions, and is played cooperatively to create a so-called "stereo" effect, which can also be regarded as a technical means for controlling the center position of a sound stage. Therefore, in the embodiment, the sound source information can be played according to the first sound field center position by coordinating the playing volume of each sound box.
Referring to fig. 2, if the first sound stage center is located at the point X in fig. 2 accurately, the 6 sounds shown in fig. 2 will be played according to the following strategy: the sound 1, the sound 2 and the sound 3 are played at relatively high volume, and the volume of the sound 2 is the same as that of the sound 3; the sound 4, the sound 5, the sound 6 are played at a relatively low volume, and the volumes of the sound 4 and the sound 5 are the same. Thus, the sound wave distribution in the vehicle interior space is bilaterally symmetrical, and the front-row sound wave energy is stronger than that of the rear row, so the first sound field center position will be located at the center of the front row, that is, between the driver and the passenger in the passenger seat.
Similarly, for example, in other scenarios, if the first sound field center is located near the driver, the sound in the vicinity of the driver may be played at a higher volume, and the sound away from the driver may be played at a lower volume or not played, so that the sound energy is most concentrated in the vicinity of the driver. Or if the center of the first sound field is positioned at the geometric center of the space in the vehicle, all the sounds can be played at the same volume, so that the sound waves in the space are distributed more uniformly.
And 103, determining a second sound playing parameter according to the noise information in the vehicle and the first sound playing parameter.
The determination of the first sound reproduction parameter takes into account only the position of the passenger. The passenger's demand for sound playing during driving is not only based on location, but also further changes according to actual conditions. Therefore, in this embodiment, the first sound playing parameter is continuously adjusted to determine the second sound playing parameter, so as to meet the changing requirement of the passenger.
The adjustment of the first sound playing parameter is based on the noise information in the vehicle, and the noise information in the vehicle can be acquired by a microphone in the vehicle. Adjusting a first sound playing parameter, which may be specifically adjusting the first sound stage center position to a second sound stage center position in this embodiment; and determining the second sound playing parameter according to the second sound field center position. Namely, the center position of the sound field is changed to adapt to different requirements of passengers.
Specifically, the noise type and the noise position of the noise information may be identified, and the first sound stage center position may be adjusted according to the noise type and the noise position to determine the second sound stage center position. The noise type may include human voice noise or environmental noise, and the noise position is the sound source bearing of the noise. Different noise types and noise positions may mean different requirements for the passengers, and the respective adjustment of the first sound stage center position may be different. The present embodiment is not particularly limited.
And 104, playing sound source information according to the second sound playing parameter.
Similarly, after the second sound playing parameter is determined, the sound source information can be played according to the setting of the second sound playing parameter, so that each passenger can still automatically obtain an ideal sound playing effect after the requirement changes.
According to the technical scheme, the beneficial effects realized by the embodiment are as follows: the first sound playing parameter is determined according to the position of a passenger, and the first sound playing parameter is adjusted according to the noise information in the vehicle so as to determine the sound playing parameter, so that the playing effect of sound source information is automatically changed when the requirement of the passenger for sound playing changes, different requirements of the passenger are met, and each passenger can automatically obtain an ideal sound playing effect.
Fig. 1 shows only a basic embodiment of the method of the present disclosure, and based on this, certain optimization and expansion can be performed, and other preferred embodiments of the method can also be obtained.
Fig. 3 is a schematic flow chart of a method for playing sound in a vehicle according to another exemplary embodiment of the present disclosure. The embodiment can be applied to electronic equipment. In this embodiment, a specific technical scheme of the in-vehicle sound playing method will be described in combination with the following specific application scenarios: during the driving of the vehicle, the passenger starts talking, and it is not desirable that the playing of the first type sound source information interferes with the talking. As shown in fig. 3, the present embodiment includes the following steps:
And 303, playing the sound source information according to the first sound playing parameter.
The detailed description of steps 301-303 refers to the embodiment shown in fig. 1, and is not repeated herein.
The state of playing the sound source information according to the first sound playing parameter is maintained until the passenger starts talking. In this embodiment, the sound source information may specifically be the first type of sound source information. And the noise information in the car is monitored in real time in the playing process. When the passenger starts talking, the talking sound of the passenger can be obtained as the noise information by monitoring. And further identifying the noise type and the noise position of the noise information through audio analysis.
Obviously, in this embodiment, the type of noise is human voice noise, and the noise location is the location where the talking passenger is located. The process of identifying noise information may be regarded as a basic technology in the field of audio analysis, and is not specifically limited in this embodiment, and any technical means capable of achieving the same or similar effects may be combined in the overall scheme of this embodiment.
If the type of noise is human voice noise, it is determined that the passenger is talking at that time, and it is not desirable that the play of the first type sound source information interferes with the conversation. Further, the first sound stage center position is adjusted in a direction away from the noise position (i.e., the position where the passenger talks) to determine the second sound stage center position.
For example, the first sound stage center position is originally located in the middle of the rear row. When the noise location is in the rear row of the vehicle, it indicates that the rear passenger is talking. The first soundstage centre position is now moved towards the front row to determine a second soundstage centre position, which is in particular located in the middle of the front row. The second sound stage center position is distant from the noise position with respect to the first sound stage center position.
And step 306, determining a second sound playing parameter according to the second sound field center position.
And 307, playing the sound source information according to the second sound playing parameter.
And after the second sound field center position is determined, determining the second sound playing parameter according to the second sound field center position. And playing the sound source information according to the second sound playing parameter. Since the center position of the second sound field is relatively far away from the noise position, the sound source information is played by the second sound playing parameter, so that the sound wave intensity at the noise position can be reduced, and the interference of the sound source information playing on conversation is avoided.
According to the technical scheme, the beneficial effects realized by the embodiment are as follows: through the discernment to noise information, judge out the application scene and the corresponding demand of passenger's conversation automatically to the broadcast of automatic adjustment sound source information makes sound field central point put and keeps away from passenger's conversation position, has avoided the interference that sound source information broadcast produced the conversation, and need not the passenger's manual work and adjusts the operation.
Fig. 4 is a schematic flowchart of a method for playing sound in a vehicle according to another exemplary embodiment of the present disclosure. The embodiment can be applied to electronic equipment. In this embodiment, a specific technical scheme of the in-vehicle sound playing method will be described in combination with the following specific application scenarios: during the running of the vehicle, the environmental noise in the vehicle is increased due to the opening of the window, and the environmental noise is not expected to influence the playing of the first type sound source information. As shown in fig. 4, the present embodiment includes the following steps:
And step 403, playing the sound source information according to the first sound playing parameter.
The detailed description of steps 301-303 refers to the embodiment shown in fig. 1, and is not repeated herein.
Ambient noise within the vehicle is typically maintained at a relatively low volume range before the windows are opened. At this time, the state of playing the sound source information according to the first sound playing parameter is always maintained. In this embodiment, the sound source information may specifically be the first type of sound source information.
When the window is opened, the state of opening the window can be acquired through a control interface in the automobile, and then local noise detection is started. And further identifying the noise type and the noise position of the noise information through audio analysis. Because the vehicle speed and the degree of opening the vehicle window are different, the change conditions of the local environmental noise are different, and whether the subsequent steps are executed or not can be judged according to whether the detected local environmental noise intensity is greater than a preset threshold value or not.
It should be noted that in other scenarios, the environmental noise change that may be caused by the vehicle starting from a standstill or the environmental noise change caused by any other reason may be handled by the technical solution similar to this embodiment. The processing principle is the same, and repeated description is not needed.
Obviously, in this embodiment, the noise type is ambient noise, and the noise position is the position of the opened window. The process of identifying noise information may be regarded as a basic technology in the field of audio analysis, and is not specifically limited in this embodiment, and any technical means capable of achieving the same or similar effects may be combined in the overall scheme of this embodiment. Generally, the subsequent steps can be entered when the intensity of the environmental noise changes by more than a preset threshold.
And when the noise type is environmental noise and the intensity variation exceeds a preset threshold value, judging that the environmental noise generates interference on the playing of the first type of sound source information at the moment. Further, the first sound stage center position is adjusted to a direction close to the noise position (i.e., the sound source position of the ambient noise) to determine the second sound stage center position.
For example, the first sound stage center position is originally located in the middle of the rear row. And when the noise position is positioned on the right window of the front row in the vehicle, the first sound field center position is moved to the right side of the front row so as to determine a second sound field center position, and the second sound field center position is specifically positioned on the right side of the front row. The second sound stage center position is closer to the noise position than the first sound stage center position.
And step 406, determining a second sound playing parameter according to the second sound field center position.
And step 407, playing the sound source information according to the second sound playing parameter.
And after the second sound field center position is determined, determining the second sound playing parameter according to the second sound field center position. And playing the sound source information according to the second sound playing parameter. Because the center position of the second sound field is relatively close to the noise position, the sound source information is played by the second sound playing parameter, the sound wave intensity at the noise position can be increased, so that the interference caused by the environmental noise can be resisted, and the influence of the environmental noise on the playing of the sound source information of the passenger listening is avoided.
According to the technical scheme, the beneficial effects realized by the embodiment are as follows: through the recognition of the noise information, the application scene and the corresponding requirement that the environment noise influences the listening of passengers to the sound source information playing are automatically judged, and the playing of the sound source information is automatically adjusted, so that the sound field center position is close to the sound source of the environment noise, the interference of the environment noise to the sound source information playing is avoided, and the manual adjustment operation of the passengers is not needed.
Fig. 5 is a schematic flowchart of a method for playing sound in a vehicle according to another exemplary embodiment of the present disclosure. The embodiment can be applied to electronic equipment. In this embodiment, a specific embodiment regarding the volume adjustment will be further described above with respect to the aforementioned scheme of adjusting the center position of the sound stage. As shown in fig. 5, the present embodiment includes the following steps:
In this embodiment, the first sound playing parameter includes a volume parameter. Namely, according to the setting of the volume parameter in the first sound playing parameter, the sound source information is played with a specific volume. The sound source information may be first type sound source information or second type sound source information.
Also in the present embodiment, similar to the foregoing embodiment, the noise types include human voice noise and environmental noise. Since the present embodiment mainly adjusts the volume, the noise volume of the noise information needs to be further identified, so as to adjust the volume of the sound source information according to the noise volume.
And step 504, adjusting a volume parameter in the first sound playing parameter according to the noise volume and the noise type.
And 505, determining the second sound playing parameter according to the adjusted volume parameter.
The first sound playing parameter is adjusted according to the noise information to determine the second sound playing parameter, and the actual requirement of the passenger is combined.
For the playing of the first type of sound source information, the principle of the adjustment is the same as the embodiments shown in fig. 2 to 3. The difference is that in this embodiment the adjustment will be made mainly for the volume rather than the centre position of the soundstage.
When the type of the noise information is the type of the acoustic noise, it is also determined that the passenger is talking at the moment, and it is not desirable that the playing of the first type of sound source information interferes with the conversation. The volume parameter in the first sound playback parameter will be decreased at this time to determine the second sound playback parameter.
The specific adjustment strategy is as follows: and when the volume parameter value b in the first sound playing parameter is larger than the specific value a, determining the volume parameter in the second sound playing parameter as m × b, wherein m is an adjustment coefficient, and m is more than 0 and less than 1. When the volume parameter value b in the first sound playing parameter is smaller than the specific value a, the volume parameter in the second sound playing parameter is determined to be m × a, so that the situation that the volume is too small after adjustment and passengers cannot listen to the sound is avoided. When the volume parameter value b in the first sound playing parameter is smaller than the specific value m x a, the adjustment is not performed any more, so that the situation that the volume is too small after the adjustment and the passenger cannot listen to the sound is avoided.
And when the type of the noise information is environmental noise, judging that the environmental noise generates interference on the playing of the first type of sound source information at the moment. The volume parameter in the first sound playback parameter will be increased to determine the second sound playback parameter.
For example, during the running of the vehicle, the environmental noise varies at different speeds, and generally, the higher the speed, the higher the environmental noise. Different volume adjustment levels can be set based on the vehicle speed, each level corresponds to a vehicle speed range and an enhancement coefficient, and when the vehicle speed is in the level, the volume is enhanced according to the corresponding enhancement coefficient. The vehicle speed range and the enhancement coefficient corresponding to the volume adjustment level are shown in the following table:
assume that the volume parameter value in the first sound playing parameter is c. And when the vehicle speed reaches 25km/h, determining the volume parameter in the second sound playing parameter as 1.1 c. And when the vehicle speed reaches 50km/h, determining the volume parameter in the second sound playing parameter as 1.2 c.
For playing the second type of sound source information, the specific requirements are different from the first type of sound source information. Since in almost all cases the driver needs to ensure a clear listening of the second type of sound source information. Therefore, if the sound source information is the second type of sound source information, the volume parameter in the first sound playing parameter is increased regardless of the noise type, so as to determine the second sound playing parameter.
And step 506, playing the sound source information according to the second sound playing parameter.
And after the volume parameter is adjusted according to the requirement of the passenger, determining a second sound playing parameter, and playing the sound source information at a specific volume according to the second sound playing parameter, so that the requirement of the passenger can be met.
According to the technical scheme, the method further has the following beneficial effects: through discernment passenger's demand, further carry out the adjustment to sound source information broadcast volume to realize more abundant meeting passenger's demand.
It should also be noted that in some situations the passenger may not be satisfied with the automatic adjustment of the volume in the embodiment shown in fig. 5. It is possible to manually input a volume adjustment command to intervene in the process of volume adjustment. For example, when the volume is automatically decreased, the passenger may think that the volume is too low to listen, and manually increase the volume again. When the passenger inputs a volume adjusting instruction, adjusting the volume parameter in the first sound playing parameter according to the volume adjusting instruction to determine a third sound playing parameter; and playing the sound source information according to the third sound playing parameter. I.e. played according to the passenger's settings.
Also, the passenger may be associated with a third sound playing parameter. Specifically, the Face recognition may be performed by using a camera, and the Face ID of the passenger is associated with the third sound playing parameter. I.e. means that the passenger's behavior habits are recorded. And calling a third sound playing parameter corresponding to the passenger to play sound source information when the Face ID of the passenger is matched.
