Description

Automatic control method, device, medium and electronic equipment for sound field in vehicle Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a method, device, medium and electronic device for automatically controlling the sound field in a vehicle. Background Art

[0002] When the vehicle is driving, noises such as wind noise, engine noise and air conditioning noise in the cabin directly interfere with the conversation between passengers in the car.

[0003] When the wind noise in the car is loud, if the passengers sitting in the front / back row speak at a normal volume, people sitting in seats farther away are likely to not be able to hear clearly, and the person speaking will need to speak at a very high volume. This will not only make people tired and unwilling to communicate, but may also affect people sitting in the seats next to them who are resting.

[0063] It should be noted in particular that any symbols and / or numbers in the specification that are not marked in the accompanying drawings are not drawing marks.

[0064] The optional embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0065] The embodiment provided in this application is an embodiment of a method for automatically controlling the sound field in a vehicle.

[0066] The embodiment of the present application is described in detail below with reference to FIG1 .

[0067] In step S101 , a plurality of conversation audios are collected by respective microphones of a plurality of audio components arranged in an array in a vehicle.

[0068] The audio components correspond one-to-one with each seat and include speakers and microphones. For example, as shown in Figure 2, a corresponding audio component is provided next to the driver's seat, the passenger seat, the second-row left seat, the second-row right seat, the third-row left seat, and the third-row right seat. The driver is seated in the driver's seat, the first passenger is seated in the second-row left seat, and the second passenger is seated in the second-row right seat.

[0069] Step S102: determining the respective seats of the plurality of conversation passengers in the vehicle based on the plurality of conversation audios.

[0070] Since multiple audio components are arranged in an array, a time difference of arrival algorithm (TDOA) is used to collect the sound emitted by the same sound source through the microphones in the multiple audio components arranged in an array in the vehicle. The relative position of the sound source, that is, the seat where the sound is emitted, is calculated based on the time difference between the sound reaching different microphones. In other words, it can be determined that the passenger in the seat is talking. If passengers in multiple seats in the vehicle make sounds continuously, the sounds are analyzed according to the semantic analysis model, and it can be determined that the passengers in the multiple seats are talking. The process of performing semantic analysis on the continuous sounds emitted by passengers in multiple seats according to the semantic analysis model is not described in detail in this embodiment, and can be implemented with reference to various implementation methods in the prior art.

[0071] For example, continuing with the above example, as shown in FIG2 , the first passenger and the second passenger are talking, that is, the first passenger and the second passenger are both talking passengers, while the driver remains silent and focuses on driving, and the driver is not a talking passenger.

[0072] Step S103: Based on the multiple conversation audios, the playing states of the speakers in the audio components corresponding to the respective seats of the multiple conversation passengers are controlled.

[0073] In some specific embodiments, controlling the playback status of the speakers in the audio components corresponding to the seats of the plurality of conversation passengers based on the plurality of conversation audios includes the following steps:

[0074] Step S103 - 1 : determining a current primary audio and a current secondary audio based on the differences between the multiple conversation audios.

[0075] If a passenger in a vehicle is speaking, the distances between the microphones of multiple audio components and the speaker may vary, resulting in different audio recordings of the conversation from the same sound source. By comparing the multiple audio recordings, the audio recording with the strongest signal strength can be determined to be the primary audio. This means that the microphone capturing the primary audio is closest to the speaking passenger and therefore captures a stronger signal. The microphones of other audio components are farther away from the speaking passenger and therefore capture weaker signals. To identify the differences between the multiple audio recordings, the audio recordings can be amplified proportionally, thereby magnifying the differences between the multiple audio recordings and making it easier to identify the differences.

[0076] For example, continuing with the above example, the first passenger and the second passenger are both talking passengers. If the first passenger speaks, the microphones at the six positions in the vehicle can all collect the conversation audio of the first passenger; because the audio signal strength of the conversation audio collected by the microphone set on the left side of the first passenger is the largest, the conversation audio collected by the microphone set on the left side of the first passenger is determined to be the current main audio, and the other conversation audios are all the current auxiliary audios.

[0077] Step S103-2: Based on the current main audio and the current auxiliary audio, the playback status of the speakers in the audio components corresponding to the seats of the multiple conversation passengers is controlled.

[0078] In some specific embodiments, controlling the playback status of the speakers in the audio components corresponding to the seats of the plurality of conversation passengers based on the current primary audio and the current secondary audio comprises at least the following steps:

[0079] Step S103-2a-1: When the average amplitude difference between any current secondary audio frequency and the current primary audio frequency is greater than a preset average amplitude difference threshold, determine the first audio component to which the pickup that collects the current secondary audio frequency belongs.

[0080] Step S103-2a-2: Control the speaker in the first audio component to play the current main audio.

[0081] This specific embodiment compares the amplitude value of any current auxiliary audio frequency with the amplitude value of the current main audio frequency to obtain a difference value curve; the average amplitude difference value can be obtained through the difference value curve; when the average amplitude difference value is greater than the preset average amplitude difference threshold, it indicates that there is a large difference between any current auxiliary audio frequency and the current main audio frequency, which affects the listening effect of the passengers listening to any current auxiliary audio frequency. Therefore, the speaker in the first audio component associated with any current auxiliary audio frequency plays the current main audio, so that the member can clearly hear the conversation audio with the original sound effect, thereby improving the listening effect.

[0082] In some specific embodiments, controlling the playback status of the speakers in the audio components corresponding to the seats of the plurality of conversation passengers based on the current primary audio and the current secondary audio comprises at least the following steps:

[0083] Step S103-2b-1: When the difference between the average amplitude value of any current consonant audio frequency and a preset average amplitude value exceeds a preset average difference range, processing the current consonant audio frequency based on a preset scaling ratio corresponding to the difference value to obtain a processed consonant audio frequency, and determining the second audio component to which the pickup that collected the current consonant audio frequency belongs;

[0084] Step S103-2b-2: Control the speaker in the second audio component to play the processed auxiliary audio.

[0085] The preset average difference range is a preset expected average amplitude value for enabling conversation in the car.

[0086] When the difference between the average amplitude value of any current consonant audio and the preset average amplitude value is greater than the upper limit value of the preset average difference range, the average amplitude value of the current consonant audio is reduced by the preset scaling ratio corresponding to the difference, that is, the volume of the current consonant audio is reduced, so that the consonant audio with reduced volume can be played within an appropriate volume range; when the difference between the average amplitude value of any current consonant audio and the preset average amplitude value is less than the lower limit value of the preset average difference range, the average amplitude value of the current consonant audio is increased by the preset scaling ratio corresponding to the difference, that is, the volume of the current consonant audio is increased, so that the consonant audio with increased volume can be played within an appropriate volume range.

[0087] In this specific embodiment, the volume in the car is controlled by adjusting the average amplitude value of the current auxiliary audio, thereby ensuring that conversations can be carried out in a comfortable environment in the car and avoiding the impact of excessive noise on other passengers. At the same time, it can also ensure that the conversation voice can be clearly received by each passenger participating in the conversation, thereby improving the quality of the conversation.

[0088] In some specific embodiments, the controlling the playback status of the speakers in the audio components corresponding to the seats of the plurality of conversation passengers based on the current primary audio and the current secondary audio further includes the following steps:

[0089] Step S103 - 11 , determining the third audio component to which the pickup that collects the current main audio belongs.

[0090] Step S103-12: Control the speaker in the third audio component to be in a mute state.

[0091] In this specific embodiment, the speaker of the audio component associated with the seat where the speaking passenger sits is shielded from playing his own voice, so that the speaker is in a silent state, saving power consumption in the car, reducing interference from the played voice, and ensuring that the speaking passenger's voice can be transmitted clearly.

[0092] In some specific embodiments, after determining the seats of the plurality of conversation occupants in the vehicle based on the plurality of conversation audios, the method further includes the following steps:

[0093] Step S111: when the number of seats for the multiple talking passengers is less than the preset number of seats in the vehicle, the seats for the multiple talking passengers are excluded from all seats in the vehicle, and at least one remaining silent seat in the vehicle is determined.

[0094] Step S112: Control the speaker in the audio component corresponding to the silent seat to be in a silent state.

[0095] Silent seats are seats where passengers are not engaged in conversation or are otherwise unoccupied. For example, as shown in Figure 2, these seats include the driver's seat, the unoccupied passenger seat, the third row left seat, and the third row right seat.

[0096] In this specific embodiment, if there is a silent seat in the vehicle, the speaker in the audio component corresponding to the silent seat is controlled to be in a silent state to ensure that the conversation in the car will not interfere with the passengers who are not participating in the conversation, so that the passengers who are not participating in the conversation can focus on their work in a quiet environment.

[0097] In some specific embodiments, the method further comprises the following steps:

[0098] Step S121: Control the microphones of the plurality of audio components to always remain in an open state.

[0099] In this specific embodiment, the microphones of all audio components in the vehicle are kept in an open state at all times, so that every passenger in the vehicle can participate in the conversation at any time, thereby improving the intelligence of the in-vehicle sound field.

[0100] This embodiment of the present application uses multiple collected conversation audios to determine the seats of multiple passengers in the vehicle. Based on the collected conversation audios, the speaker status of the audio components corresponding to each of the seats is controlled. By controlling the audio components associated with each passenger's seat, each participant in the conversation can clearly hear the voice of the speaking passenger, achieving intelligent control of the in-vehicle sound field and ensuring the quality of the conversation.
