Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Referring to fig. 1, a flow diagram of the disclosed sound field adjusting method is shown. May include the steps of:
s101, sound field adjustment is carried out according to the position distribution of the user in the specific area, and an initial balance point of the sound field is obtained.
In order to improve the flexibility of sound field adjustment, the scheme disclosed by the invention can adjust the sound field by combining the current state of the user and/or an adjustment instruction issued by the user on the basis of position distribution, so that the personalized requirements of the user can be better met on the basis of ensuring the sound reproduction quality of a specific area, and the user experience is improved.
For example, the specific area in the present disclosure may be an interior of a vehicle, an interior of an airplane, a movie theater, a studio, etc., and an area where a plurality of speaker units may be installed at different positions.
In the practical application process, after a user enters a specific area and selects a seat to sit well, the position distribution of the user can be obtained firstly, sound field adjustment is carried out according to the position distribution, and an initial balance point of the sound field is determined. Taking the specific area as the vehicle interior as an example, if the user is seated in the driving seat and the passenger seat, the initial balance point may be determined to be in the middle of the driver seat.
In the actual application process, the situation that the user changes the seat may occur. Taking the specific area as the interior of the vehicle as an example, the user moves from the right rear seat to the left rear seat, and for the situation, whether the time for the user to leave the original seat exceeds the preset time length can be judged, and if the time exceeds the preset time length, the sound field adjustment can be triggered; if the preset time is not exceeded, the initial balance point can be maintained unchanged, and frequent adjustment of the sound field caused by the fact that the user only leaves the original seat for a short time is prevented. As an example, the preset time period may be 3 s.
It is to be understood that, before the sound field adjustment is performed according to the current state of the user and/or the adjustment instruction issued by the user, the balance point determined by the last adjustment may be referred to as an initial balance point regardless of the sound field adjustment performed several times according to the position distribution, as a basis for the sound field adjustment according to the current state and/or the adjustment instruction.
S102, acquiring the current state of the user and/or an adjusting instruction issued by the user.
S103, sound field adjustment is carried out according to the current state and/or the adjustment instruction, and a post-adjustment balance point of the sound field is obtained.
As introduced above, the disclosed solution may perform sound field adjustment in conjunction with the current state of the user and/or adjustment instructions issued by the user, as exemplified below.
1. Sound field adjustment based on current state of user
(1) The current state of the user may be a sleep state.
For this, the current states of all users in a specific area can be monitored in real time, and whether the users in a sleep state exist or not is judged; if the user in the sleep state is judged to exist, the initial balance point can be adjusted away from the user in the sleep state, and the adjusted balance point is obtained. That is to say, after the user falls asleep, the volume of the position where the user is located can be reduced, and the influence on the sleep quality of the user is prevented.
As an example, after completing the sound field adjustment for the user in the sleep state, the user monitoring may be further continued to determine whether the user in the sleep state enters the awake state, and if it is determined that the user in the sleep state enters the awake state, the post-adjustment balance point may be made to be close to the user entering the awake state, so as to obtain a new post-adjustment balance point. That is, when the user enters the awake state from the sleep state, the volume of the location where the user is located can be automatically increased.
As an example, when it is detected that the user enters the awake state from the sleep state, the sound volume of the location of the user may not be automatically turned up, but the sound field may be adjusted according to an adjustment instruction issued by the user when needed, as described in detail below.
(2) The user's current status may also be a fatigue status if the particular area is inside a vehicle.
Aiming at the problem, the current state of the vehicle driver can be monitored in real time, and whether the vehicle driver is in a fatigue state or not is judged; if it is determined that the vehicle driver is in a tired state, the initial balance point may be brought close to the vehicle driver, and the adjusted balance point may be obtained. That is to say, when the driver drives fatigue, the volume of the position where the driver is located can be adjusted to play a role in warning the driver.
As an example, after completing the sound field adjustment for the driver in the fatigue state, the user monitoring may be continued to determine whether the driver enters the non-fatigue state, and if it is determined that the driver enters the non-fatigue state, the adjusted balance point may be adjusted away from the driver to obtain a new adjusted balance point. That is, when the driver enters the non-fatigue state from the fatigue state, the volume of the position where the driver is located can be automatically reduced.
As an example, when it is detected that the driver enters the non-fatigue state from the fatigue state, the sound volume at the position of the driver may not be automatically reduced, but the sound field may be adjusted according to an adjustment instruction issued by the driver when needed, as described in detail below.
In the present disclosure, the determination condition of the sleep state, the determination condition of the awake state, the determination condition of the fatigue state, the determination condition of the non-fatigue state, and the like may be determined in accordance with the actual application requirements, and the present disclosure is not particularly limited thereto.
2. Sound field adjustment according to adjustment instructions issued by users
In the scheme of the disclosure, the adjustment instruction is used for adjusting the volume of the designated position. Specifically, the designated location may be a location where a user who issues the adjustment instruction is located; or may be a user-specified location at which the adjustment instruction is issued. That is, in the actual application process, the user a can adjust the volume of the position where the user a is located by adjusting the instruction; or the volume of the position where other users are located can be adjusted through the adjusting instruction.
As an example, the adjustment instruction may be obtained by voice. For example, voice data "a little less sound" input by a single user may be acquired, and an adjustment instruction for turning down the volume may be obtained through semantic understanding; or, the voice data of multiple users in the conversation process can be acquired, wherein the voice data of the co-driving is too small and not heard clearly, and the adjustment instruction for increasing the volume is obtained through semantic understanding. In this example, if the designated location is not included in the adjustment instruction, the location where the user who issued the adjustment instruction is located may be determined as the designated location based on the sound source localization technology.
As an example, the adjustment instruction may be obtained by a key manner. For example, a key may be provided near the seat where the user sits, and different keys may correspond to different positions, so that when the user inputs key operation information, an adjustment instruction may be extracted from the key operation information. The keys in this example may be physical keys or virtual keys, which may not be specifically limited in the present disclosure.
Specifically, when the sound field is adjusted according to the adjustment instruction, whether the adjustment instruction is received or not may be determined first; and if the adjustment instruction is judged to be received, determining the specified position according to the adjustment instruction, so that the adjusted balance point is opposite to the specified position to meet the requirement of the adjustment instruction on the volume.
For example, in the solution of the present disclosure, the requirement of the adjustment instruction on the volume size is satisfied by making the adjusted balance point relative to the specified position, which can be embodied in at least the following two cases:
(1) if the adjusting instruction is used for turning down the volume, the initial balance point can be turned away from the specified position, and the purpose of turning down the volume of the specified position is achieved. Specifically, the volume of the speaker unit mounted corresponding to the specified position may be turned down so that the entire effect of the specific area appears as the initial balance point is turned away from the specified position.
(2) If the adjusting instruction is used for adjusting the volume to be large, the initial balance point can be close to the specified position, and the purpose of adjusting the volume to be large at the specified position is achieved. Specifically, the volume of the speaker unit mounted corresponding to the specified position may be turned up so that the entire effect of the specific area appears as the initial balance point is close to the specified position.
As an example, after receiving an adjustment instruction issued by a user, the solution of the present disclosure may further perform the following processing: judging whether the specific area is provided with only one user or not; if only one user exists in the specific area, the playing volume of the audio output system can be adjusted according to the adjusting instruction; otherwise, the specified position can be determined according to the adjusting instruction and the sound field adjustment is carried out according to the introduction.
That is, in order to simplify the processing, when there is only one user in a specific area, after the user issues an adjustment instruction, the overall playing volume of the audio output system can be directly adjusted, that is, the position of the balance point relative to the user is changed without performing sound field adjustment.
3. Adjusting sound field according to current state and adjusting instruction
For example, the sound field adjustment is performed in two ways, which can be embodied as: when the user enters the sleep state from the waking state, the sound field can be adjusted through the current state, and the volume is reduced; when the user enters the waking state from the sleeping state, the sound field can be adjusted through the adjusting instruction of 'louder sound' issued by the user, and the volume is increased.
For example, when there are at least two users in a specific area, if one user is in a sleep state and another user issues an adjustment command of "louder sound", the sound field can be adjusted by combining the requirements of the two users, and the requirements of the two users can be met.
In summary, according to the scheme of the present disclosure, an initial balance point in the scene may be determined according to the position distribution of the user in the specific area, and then sound field adjustment is performed based on the initial balance point in combination with the personalized requirements of the user, that is, the current state of the user and/or the adjustment instruction issued by the user, and a balance point after adjustment is determined to meet the current requirements of the user. According to the scheme, the flexibility of sound field adjustment can be improved, the personalized requirements of users can be better met on the basis of ensuring the sound reproduction quality of a specific area, and the user experience is improved.
It is to be understood that after performing sound field adjustment according to the current state and/or the adjustment instruction of the present disclosure, if the position distribution of the user in a specific area is changed, the sound field adjustment may be performed as appropriate. The following examples are given. In the present disclosure, a user who performs sound field adjustment according to the current state and/or the adjustment instruction may be referred to as an adjusted user.
If the position distribution is changed due to the fact that the user leaves a specific area, for example, the user gets off a car, and the individual personalized requirements of the user who does not leave the specific area are not changed, the sound field adjustment may not be performed.
If the position distribution changes because the adjusted user replaces the seat, the position after replacement can be obtained, and the sound field adjustment is carried out according to the position after replacement, so that the volume corresponding to the position after replacement and the position before replacement are the same, namely, the volume before and after the adjusted user replaces the seat is kept unchanged. Or, after the adjusted user exchanges the seat, the sound field adjustment may not be performed, but the latest current state and/or the adjustment instruction of the user are continuously obtained, and the sound field adjustment is performed according to the actual requirement, and the specific process may refer to the description above and will not be described herein again.
