Exemplary method
Fig. 1 is a schematic flowchart of a speaker control method according to a first exemplary embodiment of the present application.
The embodiment can be applied to electronic equipment, and particularly can be applied to a server or a general computer. As shown in fig. 1, a speaker control method according to a first exemplary embodiment of the present application includes at least the following steps:
The current position specifically refers to coordinates of a position of the movable device at the current time corresponding to the world coordinate system, and the target position specifically refers to coordinates of a destination position to which the movable device is to be moved corresponding to the world coordinate system.
In one possible implementation, the current position and the target position of the mobile device are obtained at preset time intervals or in real time when the mobile device starts to navigate. In another possible implementation manner, user requirements in the mobile device are acquired, whether voice broadcasting is needed or not is determined, and when the voice broadcasting is needed, the current position and the target position of the mobile device are acquired.
A movable device particularly refers to an object capable of moving, such as a car. For example, the mobile device is an automobile, when the automobile has a navigation demand, a driver or a passenger in the automobile inputs a destination on a navigation page of a central control screen of the automobile, and then determines a position of the destination, which corresponds to a high-precision map stored in the automobile, on the automobile, wherein the position is a target position; a global positioning system is usually provided in an automobile, and the current position of the automobile can be determined according to the global positioning system.
The first distance indicates a length of a travel path between the current position to the target position. Specifically, a first driving path planned in advance by the movable equipment is obtained, the starting point of the first driving path is the starting point of navigation, the end point of the first driving path is the destination of navigation, the destination of navigation is the target position, the position of the current position on the first driving path is determined, the driving path between the current position and the target position of the movable equipment in the first driving path is determined as a second driving path, and the length of the second driving path is determined as a first distance.
And 103, determining a loudspeaker parameter corresponding to the first distance.
The speaker parameters indicate one or more variables of the speaker, each of which may control other variables that vary as they vary. Considering that the distance of the mobile device changes rapidly during the driving process, the distances within a certain range may correspond to the same speaker parameters, specifically, a plurality of different distances are determined within a certain distance interval according to a preset data generation rule, and the data generation rule may be an equal interval, an equal difference, an equal product, or other data generation manners. The method comprises the steps of regulating and controlling loudspeaker parameters aiming at each distance, enabling a plurality of different distances to correspond to different loudspeaker parameters respectively, enabling the loudspeaker parameters to indicate the distance, storing the different loudspeaker parameters corresponding to the different distances in the electronic equipment, determining a first distance, determining a second distance closest to the first distance from the different distances, and determining the loudspeaker parameters corresponding to the second distance as the loudspeaker parameters corresponding to the first distance.
Here, the speaker parameter includes, but is not limited to, the sound volume of the speaker, i.e., the sound volume of the speaker is a variable, which may affect the input signal of the speaker, and the input signal may also be a digital sound signal or a digital voice signal. In order to reflect the sound distance, the sound reproduction volume of the speakers corresponding to a plurality of different distances is different, and the distance and the sound reproduction volume are inversely proportional to each other.
And 104, controlling the output of the loudspeaker according to the loudspeaker parameter.
The speaker is usually matched with an audio digital-to-analog converter (audio DAC), and the audio DAC can convert a digital signal into an analog signal, and then amplify the analog signal through an audio amplifier (audio amplifier), so as to drive the speaker to play an analog sound signal. Specifically, an input signal is obtained, where the input signal may be a digital sound signal or a digital voice signal, and when the input signal is a digital sound signal, the input signal is processed through parameters of a speaker, so as to obtain a first digital sound signal, and the first digital sound signal controls output of the speaker through an audio digital-to-analog converter and an audio amplifier. The sound output by the loudspeaker can reflect the distance between the current position and the target position, for example, when the mobile equipment is an automobile, and the distance between the automobile and the target position is long, the sound played by the loudspeaker gives a user the feeling of transmitting from far; when the distance between the automobile and the target position is close, the sound played by the loudspeaker gives a user a feeling of coming from the close distance until the automobile reaches the target position.
It should be noted that the speaker may be an internal speaker of the mobile device, or may be an external speaker used for navigation in the mobile device, for example, an internal speaker of a mobile phone.
Referring to fig. 4, the input signal controls the output of the speaker after passing through the speaker parameter adjustment, the audio digital-to-analog converter, and the audio amplifier.
The sound signal collection method provided by the embodiment has the beneficial effects that:
according to the embodiment, the output of the loudspeaker is controlled through the loudspeaker parameter corresponding to the distance between the current position and the target position, so that a user can feel the distance between the current position and the target position, the experience of the user is improved, the spirit of a driver is more concentrated, and the safety of people and vehicles is ensured.
Fig. 2 shows a flow chart of the step of determining the speaker parameter corresponding to the first distance in the embodiment shown in fig. 1.
As shown in fig. 2, on the basis of the embodiment shown in fig. 1, in an exemplary embodiment of the present application, the step of determining the speaker parameter corresponding to the first distance shown in step 103 may specifically include the following steps:
The starting position is the coordinate where the position of the movable device at the time of starting the navigation corresponds to the world coordinate system. For example, the mobile device is an automobile, when the automobile has a navigation demand, a driver or a passenger in the automobile inputs a starting location and a destination on a navigation page of a central control screen of the automobile, and then determines a location, corresponding to the starting location, on a high-precision map stored in an electronic device in the automobile, where the location is the starting location; of course, the driver or passenger may simply input the destination, and at this time, the position where the movable device is located is determined as the start position.
In order to determine how far and how close the mobile device is from the target location, it is generally necessary to determine a second distance between the starting location and the target location, the second distance indicating the length of the travel path between the starting location and the target location, it being apparent that the travel path between the current location and the target location is part of the travel path between the starting location and the target location.
Specifically, after the start position and the target position of the navigation are determined, the travelable road surface between the start position and the target position may be determined according to the high-precision map stored in the electronic device, the travel path of the mobile device may be planned in the travelable road surface area according to the road condition of the travelable road surface, the length of the travel path is determined as the second distance, the second distance indicates the distance that the mobile device needs to travel from the start position to the target position, that is, the distance when the mobile device travels according to the travel path corresponding to the second distance, and the travel path corresponding to the second distance is the first travel path mentioned in the content specifically described in step 102.
The ratio between the first distance and the second distance indicates the driving progress of the movable device, namely the distance between the movable device and the target position, obviously, the first distance between the current position and the target position cannot accurately reflect the distance between the current position and the target position, and the ratio has scale invariance and is insensitive to the distance, so that the distance between the movable device and the target position can be more accurately reflected by the ratio between the first distance and the second distance.
Specifically, according to a preset data generation rule, a plurality of different ratios are determined, the data generation rule may be an equidistant, an arithmetic or other data generation manner, for each ratio, speaker parameters are determined according to the size of the ratio, so that the plurality of different ratios respectively correspond to different speaker parameters, here, the speaker parameters may indicate the distance, the speaker parameters respectively corresponding to the plurality of different ratios are stored in the electronic device, then, after the ratio of the first distance to the second distance is determined, a third ratio closest to the ratio of the first distance to the second distance may be determined from the plurality of different ratios, and the speaker parameters corresponding to the third ratio are determined as the speaker parameters corresponding to the first distance. The parameters of the loudspeaker include but are not limited to the sound volume, when the parameter of the loudspeaker is the sound volume, the sound volume of the loudspeaker corresponding to a plurality of different ratios is different, the magnitude of the ratio is in inverse proportion to the magnitude of the sound volume, and the sound volume of the loudspeaker reflects the sound distance.
According to the embodiment, the loudspeaker parameters corresponding to the first distance are determined through the first distance between the current position of the movable equipment and the target position and the ratio of the second distance between the initial position of the movable equipment and the target position, and when the output of the loudspeaker is controlled according to the determined loudspeaker parameters, a user can more accurately sense the distance between the current position and the target position, so that the user experience is further improved, the spirit of a driver is more concentrated, and the safety of people and vehicles is ensured.
Fig. 3 is a flow chart illustrating a step of determining a speaker parameter corresponding to the first distance according to a ratio between the first distance and the second distance in the embodiment shown in fig. 2.
As shown in fig. 3, based on the embodiment shown in fig. 2, in an exemplary embodiment of the present application, the step 1033 of determining the speaker parameter corresponding to the first distance according to the ratio between the first distance and the second distance may specifically include the following steps:
The distance interval may be a simpler indication of how far the current position of the movable apparatus is from the target position relative to the ratio of the first distance, the first distance and the second distance. The second distance is divided to obtain a plurality of distance intervals, for example, the second distance may be equally divided, or of course, the second distance may also be divided according to an arithmetic difference series or an arithmetic product series, and the dividing method is not limited in this embodiment.
For example, the second distance is B, and the second distance can be equally divided to obtain N distance intervals, where the distance intervals include [0, B/N ], [ B/N, 2 × B/N), … …, [ i × B/N, (i +1) × B/N), … …, [ (N-1) × B/N, B ].
And defining the sound distance degree of the distance sections, and determining the loudspeaker parameters according to the sound distance degree corresponding to the defined distance sections for each distance section. And then, determining the loudspeaker parameters corresponding to the distance interval of the first distance as the loudspeaker parameters corresponding to the first distance.
For example, the second distance is 3n, the second distance value is divided into 3 parts, the obtained distance intervals include [0, n ], [ n, 2n ], and [2n, 3n ], where the sound distance degree of the [0, n ] distance interval is defined as near, the sound distance degree of the [ n, 2n) distance interval is defined as medium, the distance degree of the [2n, 3n ] is far, the speaker parameters are playback volumes, the playback volumes of the speakers corresponding to the three distance intervals are determined based on the sound distance degrees, the playback volume corresponding to [0, n) represents the sensation that the sound comes from near, the playback volume corresponding to [2n, 3n ] represents the sensation that the sound comes from far, and the playback volume corresponding to [ n, 2n) represents the sensation that the sound comes from middle. Assuming that the distance interval of the first distance is [2n, 3n ], determining the playback volume of the loudspeaker corresponding to [2n, 3n ] as the loudspeaker parameter corresponding to the first distance, so that the sound output by the loudspeaker shows a feeling of coming from a far place.
According to the embodiment, the distance interval corresponding to the first distance is determined through the first distance between the current position of the movable equipment and the target position and the ratio of the second distance between the initial position of the movable equipment and the target position, the loudspeaker parameter corresponding to the first distance is determined based on the distance interval, the output of the loudspeaker is controlled according to the determined loudspeaker parameter, the distance between the current position of the movable equipment and the target position can be reflected accurately, the user experience is further improved, the spirit of a driver is more concentrated, and the safety of people and vehicles is ensured.

As shown in fig. 5, based on steps 101 to 103 shown in fig. 1, in another exemplary embodiment of the present application, at least the following steps are further included:
The reverb effector parameter indicates one or more variables of the reverb effector, each of which may control other variables that vary as they vary. The reverberation effector is connected with the loudspeaker, so that the voice signal after the parameter adjustment of the reverberation effector can be used as the input of the loudspeaker, thereby controlling the output of the loudspeaker.
In particular, the reverberation effector parameters include, but are not limited to, reverberation time, tail, stereo width, high frequency decay rate, high low frequency cut-off, early reflected volume, spatial size, early reflected dispersion, delay time between direct and early reflected sound, dry sound, wet sound.
In particular, the reverberation effector is an insert that generates various sound field effects and special sound effects, and can make sound present different spatial and distance senses.
In one possible implementation, when the input signal is a digital sound signal, the input signal is processed according to the speaker parameter to obtain a second digital sound signal, the second digital sound signal is processed according to the reverberation effect parameter to obtain a third digital sound signal, and the third digital sound signal passes through the audio digital simulator and the audio amplifier to control the output of the speaker.
In another possible implementation manner, when the input signal is a digital sound signal, the input signal is processed according to the reverberation effect parameter to obtain a second digital sound signal, the second digital sound signal is processed according to the speaker parameter to obtain a third digital sound signal, and the third digital sound signal passes through the audio digital simulator and the audio amplifier to control the output of the speaker.
The input information is taken as a digital sound signal as an example, the input signal is processed by utilizing the reverberation effect device parameters, and the sound signal with the spatial sense and the distance sense can be obtained, so that the loudspeaker outputs the sound with the spatial sense and the distance sense, the sound is more real, the user experience is further improved, the spirit of a driver is more concentrated, and the safety of people and vehicles is ensured. The input signal is processed by the reverberation effect parameter in a mode including but not limited to convolution reverberation, algorithm reverberation and simulation reverberation, and the convolution reverberation is convolved with the input signal by using Impulse Responses (IR for short) file to obtain digital sound signal with space sense and distance sense; the algorithm reverberation obtains a digital sound signal with space sense and distance sense by generating complex delay segments, simulating the delay expression of a reverberation sound field and reproducing sound segments in the early stage of sound reflection; the analog reverberation specifically refers to an analog hardware reverberation device, so that a digital sound signal with a spatial sense and a distance sense is obtained.

and 701, determining a preset voice sample and a corpus corresponding to the first distance.
The corpus refers specifically to language text. The corpus corresponding to the first distance may be navigation information or other information, the navigation information indicates the first distance between the current position and the target position, and the other information may be other requirements of the user, for example, voice interaction information between a passenger in an automobile and a machine. The preset voice sample comprises voice signals corresponding to the voice recording distance, the voice recording distance is the distance between a speaker and the voice collecting device, the speaker speaks at the position corresponding to the voice recording distance, and the voice signals of the speaker collected by the voice collecting device are the voice signals corresponding to the voice recording distance. For example, the second distance is 3n, the second distance value is divided into 3 parts, and the obtained distance interval includes [0, n ], [ n, 2n ], and [2n, 3n ], at this time, it is defined that the sound distance degree of the [0, n) distance interval is near, the sound distance degree of the [ n, 2n) distance interval is medium, and the distance degree of the [2n, 3n ] is far, and accordingly, three different sound recording distances of near, medium, and far are selected to collect the voice signal of the speaker. In order to achieve the best sound receiving effect, a speaker can speak at positions 1 m, 3 m and 5 m away from a microphone respectively, wherein the sound distance degree corresponding to 1 m is near, the sound distance degree corresponding to 3 m is middle, and the sound distance degree corresponding to 5 m is far, at the moment, the sound recording distances corresponding to different sound recording distances are different in distance and proximity, the direction between the speaker and the microphone is not limited, and the sound signals corresponding to the three sound recording distances are stored in a database. If the first distance is 1.5n, the voice sample falls into the range of [ n, 2n), and the corresponding voice distance is middle, at this time, it can be determined that the preset voice sample with the first distance of 1.5n is a voice signal with the voice recording distance of 3 meters.
Here, the speech synthesis technology may be used to synthesize a digital speech signal corresponding to the corpus according to the preset speech sample, and thus, the speech input data is a digital speech signal synthesized by the corpus and the preset speech sample. Specifically, acoustic features corresponding to the phonetic features are extracted from a preset voice sample, speech synthesis is performed on the speech material according to the acoustic features corresponding to the phonetic features, and digital speech signals corresponding to the speech material are output. After the preset voice sample and the corpus corresponding to the first distance are determined, voice synthesis can be performed by using the preset voice sample and the corpus, and different voice samples have different distance senses, so that voice input data synthesized by using different voice samples also have different distance senses, namely, the synthesized voice input data can more accurately reflect the distance degree between the current position and the target position of the mobile equipment.
And 703, controlling the output of the loudspeaker according to the loudspeaker parameters and the voice input data.
The voice input data are processed through the loudspeaker parameters, so that the voice input data can reflect the distance between the current position and the target position.
Referring to fig. 8, the voice input data is processed by the speaker parameter adjustment, the audio digital-to-analog converter, and the audio amplifier to control the output of the speaker.
The voice input data corresponding to the corpus synthesized according to the preset voice sample is processed through the loudspeaker parameters, so that the loudspeaker outputs the voice reflecting the distance between the current position and the target position, the user experience is further improved, the spirit of a driver is more concentrated, and the safety of people and vehicles is ensured.
