Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be understood that the terms "first," "second," and "third," etc. in the claims, specification and drawings of the present disclosure are used for distinguishing between different objects and not for describing a particular sequential order. The terms "comprises" and "comprising" when used in the specification and claims of the present disclosure, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. It is also to be understood that the terminology used in the description of the present disclosure is for the purpose of describing particular embodiments only, and is not intended to be limiting of the disclosure.
Referring to fig. 1, the present invention provides a method for controlling playing of an in-vehicle sound field, comprising:
step 100: and acquiring the sound source type of the sound source to be played and the sounding position of the sound source to be played.
The speaker in the vehicle can play various sound sources, and can play sound sources of other devices connected with the vehicle, such as a mobile phone and the like. Common sound sources played in the vehicle comprise navigation broadcasting sound sources, voice interaction sound sources and obstacle reminding sound sources. The audio to be played refers to audio which is not yet played by the in-vehicle speaker, and the audio marks the sounding position of the audio when in transmission, wherein the sounding position can be related to the audio type of the audio, and the audio type characterizes the sound field control played by the in-vehicle speaker, such as the whole vehicle sharing and the main driving exclusive sharing. And the in-car speakers play audio when the whole car is shared, and the in-car speakers only play audio at the main driving position when the main driving is exclusively shared.
In some embodiments, the sound producing locations include front right, front left, rear right, rear left; and the vehicle loudspeakers respectively correspond to the corresponding positions of the front right, the front left, the rear right and the rear left of the vehicle. Naturally, if speakers at other positions are provided, the sounding positions can be set correspondingly.
In the step, when the sound source to be played is acquired, the sound source type of the sound source to be played is identified and the sounding position of the sound source to be played is acquired; the sound source to be played and the sounding position are all transmitted by the requested functional module through the Can (Controller Area Network ). The function module can be an obstacle recognition module, a voice interaction module, a navigation module, a music module and the like.
Step 200: and determining sound field playing parameters according to the sound source type and the sound producing position of the sound source to be played, and controlling an in-vehicle loudspeaker corresponding to the sound producing position to play the sound source to be played according to the sound field playing parameters.
After the sound source type and the sounding position of the sound source to be played are obtained, the playing parameters of the sound field, namely, the parameter setting of the playing is modified, can be determined. Wherein the sound producing locations may be indicated by letters, e.g. ALL locations; FR: FRONT right, FL: FRONT LEFT, RR: REAR RIGHT, right-rear, RL: REAR LEFT represents REAR LEFT. It should be noted that the above words, numbers or codes are only used as examples, and other information may be used, for example, the numbers are used to represent four positions, namely 0, 1, 2, 3 and 4; the present invention is not particularly limited herein.
The sound emission position determines the control of the in-vehicle speaker having directivity with respect to the user, the front right, rear right indicating the right-side direction information, and the front left, rear left indicating the left-side direction information. When a user drives the vehicle, the vehicle speaker at the front left position broadcasts audio when the vehicle needs to turn left, and the confirmation information of the left direction of the user is given, so that the user can quickly confirm that the operation intention of the left turn is correct, and the user does not need to confirm again through the vehicle display screen, thereby improving the experience degree of the user.
Taking a common language chime sound as an example, the common chime sound needs to be sounded by a headrest when a driver is dedicated to sharing, the corresponding sound type belongs to 10, and the corresponding sound source type is 13 when the driver is in a whole vehicle sharing mode. Therefore, when switching from the main driving private sharing to the whole vehicle sharing, the corresponding sound source type is required to be changed from 10 to 13, and according to the algorithm parameter (upmixer) defined in advance, the sound source type 13 is correspondingly configured as Non-media_audio3, and the parameter of the sound generating position is 1, so that the switching from the headrest player to the whole vehicle player can be completed only by setting configuration=non-media_audio3, and the parameter of the sound generating position=0. Of course, if the sounding position is changed, parameters of the sounding position can be modified to change the audio played by the speaker in the vehicle, and the use scenes of voice interaction between users at different positions in the vehicle and the vehicle respectively are common.
According to the invention, through obtaining the information of different playing sound sources and the sounding positions required by the information, sound field playing parameters can be determined according to the sounding positions and the types of the sound sources; the in-vehicle speakers corresponding to the sound production positions can be controlled to play the sound sources to be played according to the sound field play parameters, the audio of the play sound sources is not required to be analyzed, and the in-vehicle speakers can be directly controlled according to the audio types and the sound production positions.
According to the invention, the voice interaction service and the in-vehicle speaker broadcasting at different positions are combined, so that the voice broadcasting has directional sense, the voice interaction service of a 3D sound field is provided for a user, the voice interaction service is utilized to help the user to perfect the confirmation of other vehicle functions on the directional sense, the accuracy of man-machine interaction information is improved, and the user experiences the audio experience of the 3D effect.
Further, in the method for controlling playing of sound field in vehicle, before step 110, the method further includes:
when an audio focus of a sound source to be played is applied to an audio module, the sound source type of the sound source to be played and the sounding position of the sound source to be played are sent to the audio module, and the audio module controls a loudspeaker in a vehicle to play the sound source to be played according to the audio focus.
It should be understood that two or more Android apps may play audio to the same output stream (e.g., bluetooth of a cell phone, in-car player) at the same time, and the system will mix all audio streams together to appear a mix. The audio focus can solve the problem of audio mixing, and is a value managed by the Android system process, and the value records which application, type and the like the current audio focus belongs to. The control logic using the audio focus can be realized: only one App holds the audio focus; before playing sound, applying for an audio focus, and releasing the audio focus when playing is not needed; loss of audio focus should pause playback or reduce playback volume.
Based on the above technology, when the requested functional module applies for focus to the audio module, the audio module informs the sounding position and the type of the sound source, and the audio module can realize the control of the speakers in the vehicle at different positions based on the control technology of the audio focus. For example, in the navigation usage scenario, the navigation module requests the audio module to play the audio to be played in "right turn … …", the audio module controls the in-vehicle speaker on the right side to play the audio, and the in-vehicle speakers on other positions mute or pause playing.
In step 200, when determining the sound field playing parameters, the sound field playing parameters may be implemented by a table look-up method through a preset configuration file. Because the number of speakers in the vehicle is limited, and communication interaction data is less, sound field playing parameters can be conveniently and rapidly realized by using a table look-up mode.
As shown in fig. 2, the determining the sound field playing parameter according to the sound source type and the sounding position of the to-be-played sound source includes:
step 210: presetting a first configuration table of the sound source type and first configuration parameters corresponding to the sound source type; and presetting a second configuration table of second configuration parameters of the sounding position and the corresponding sounding position.
In this embodiment, different sounding location tables are formulated according to different sound sources and different locations. It should be appreciated that the first configuration table and the second configuration table may be an integral configuration file.
Step 220: and searching a first configuration table according to the type of the sound source, determining a first configuration parameter, and determining a second configuration parameter according to a second configuration table of the sounding position Cha Di of the sound source to be played.
Parameters corresponding to the sound generation type and the sound generation position can be rapidly determined according to the sound source type and the sound generation position in the first configuration table and the second configuration table. The sound production type can be main driving sound production, whole vehicle sound production, auxiliary driving sound production, rear-row sound production, front-row sound production, rear-row left side sound production, rear-row right side sound production and the like. The sounding position can also correspond to sounding type configuration parameters, such as main driving sounding, and if the sounding position is the front left, only the front-operating in-vehicle loudspeaker plays audio; and if the sound is generated by the whole car, the sound generating position is arranged to be the front left, and only the front-operated in-car loudspeaker plays the audio.
Step 230: and taking the first configuration parameters and the second configuration parameters as the sound field playing parameters.
After the configuration parameters are determined, the configuration parameters are used as sound field playing parameters, and the audio module executes the sound field playing parameters according to an algorithm which is defined in advance.
Further, the determining the sound field playing parameter according to the sound source type and the sounding position of the to-be-played sound source further includes:
determining a playing scene to which a sound source to be played belongs, and determining an in-vehicle loudspeaker for playing the sound source to be played according to the sounding position of the sound source to be played and the playing scene; the sound field playing parameters are playing parameters of the in-vehicle loudspeaker; the sound producing position includes at least one of front right, front left, rear right, rear left.
Common play scenes include navigation broadcasting, voice interaction and obstacle reminding. Taking obstacle reminding as an example, the obstacle recognition system recognizes that the obstacle is at the left side of the vehicle, and sends the sound source type and the sound producing position, and the sound producing position of the sound source to be played for obstacle reminding requests to be played at the left side of the vehicle by the in-vehicle loudspeaker at the front left position or at the front left position and at the rear left position. The same obstacle alert applies to the right position. Similarly, the position of the obstacle in front of or behind the vehicle is identified, the sounding position can request the speaker in the vehicle in front of left and right to remind of the obstacle in front of the vehicle, and the sounding position can request the speaker in the vehicle in back of left and right to remind of the obstacle behind the vehicle. Based on the method, the user can determine the azimuth of the voice prompt according to the voice prompt of the loudspeaker in the vehicle, and simultaneously the voice prompt at different positions brings 3D effect hearing experience to the user.
In other application scenarios, the same effect can be achieved as well. For example, a navigation module in navigation broadcasting sends voice reminding contents to an audio module, and meanwhile, the voice reminding contents carry information of sounding positions, and the audio module can control a loudspeaker in a vehicle to play the reminding contents at different positions through table lookup. The playing scene corresponding to the sound source type of the navigation broadcasting is usually in the main driving position, so that the main driving is exclusive, and the sounding position is divided into front, back, left and right directions by taking the main driving position as the center. For example, the voice reminding of left turn carries the information of left sounding, and can control the speaker in the car at the front left position to play the voice reminding content; and similarly, the voice reminding such as right turning and turning around can control the in-vehicle loudspeaker at the corresponding position to broadcast.
In a voice interaction scenario, a sound producing location may be determined by identifying a user's location within a vehicle, the sound producing location being proximate to the user. The type of the sound source is a special mode during voice interaction, and the sound source is usually played by a single in-vehicle speaker, such as an in-vehicle speaker at a main driving position; of course, a plurality of in-car speakers can be used for playing, for example, a rear-row user can perform voice interaction, and the in-car speakers at the left and right sides can be controlled for performing interactive broadcasting.
In the embodiment of the invention, the sound source type and the sound production position of the sound source to be played are directly obtained, and the sound field playing parameters are determined through the configuration table, so that the control of the loudspeakers in the vehicle is realized. When the in-vehicle speaker corresponding to the sound producing position is controlled to play the sound source to be played according to the sound field playing parameters, only the target in-vehicle speaker corresponding to the sound producing position can be controlled to play the sound source to be played; or controlling other in-vehicle loudspeakers which do not correspond to the sounding position to mute or prohibit playing of the to-be-played sound source.
For example, when only the target in-vehicle speaker corresponding to the sound producing position is controlled to play the to-be-played sound source, only the audio module is informed to play the to-be-played sound source at the target in-vehicle speaker, for example, the left in-vehicle speaker is closed, and the right in-vehicle speaker is closed. Providing left-hand sound emission capability to the navigation so that the sound heard by the user is the sound emitted in the left-hand a-pillar direction.
As yet another example, the directional sense confirmation is achieved by adjusting the sound size of the in-vehicle speaker that is not the target by the up-mixer, so the sound size of the target in-vehicle speaker should be larger than the sound sizes of the other in-vehicle speakers. Or directly disable other players, closing their channels.
Still further, in other embodiments, the step 200 further includes:
after the sound field playing parameters are determined, the sound source to be played is played by the target in-vehicle speaker according to the sound field playing parameters, and playing parameters of the target in-vehicle speaker and/or other in-vehicle speakers are configured, wherein the sound production position represents the driving direction or the obstacle direction or the voice interaction position and is used for guiding a user to execute driving operation.
In this embodiment, a sound field control mode may be determined according to the sound source type, and then a target in-vehicle speaker is determined according to the sound emission position. For example, in a whole car sharing mode in a music playing state, namely, the whole car speakers play music, when a navigation request is sounded, the whole car sharing mode is converted into a main driving special sharing mode, only the front-row in-car speakers sound, and only the front-left in-car speakers sound is determined according to the sound production positions. In this embodiment, the sounding position is consistent with the direction of travel in the navigational broadcast alert, with the vehicle position where the obstacle is located, and with the user's position in the vehicle. Providing a directional confirmation and multi-position voice broadcasting experience for a user through directional sounding; the hearing experience of the user can also be improved by reducing the sound of other in-vehicle speakers.
