Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.
First embodiment
Referring to fig. 1, fig. 1 is a flowchart of an audio playing method according to a first embodiment of the present invention, the audio playing method is applied to a terminal having at least two audio players, and specifically, the audio playing method includes:
s101, acquiring a current space state of a terminal;
s102, determining audio player information corresponding to each sound channel of audio to be played according to the current space state of the terminal;
s103, playing the audio from the corresponding audio player.
The audio player of the terminal, including the speaker, the receiver, etc., is usually disposed on the top or the bottom of the front surface of the terminal, or on the bottom surface or the back surface of the terminal, etc., which is different according to the design requirements of various manufacturers. Generally, at least two audio players are provided on the terminal, which are respectively a top receiver through which a user can receive a call and a bottom speaker for playing sound. However, the earpiece and speaker differ only in function and appearance, and their substantial hardware components may be the same. Referring to fig. 2 and 3, fig. 2 shows a schematic structure of a terminal with two audio players, and fig. 3 shows a schematic structure of a terminal with four audio players.
When a video file or an audio file is to be played on the terminal, taking a terminal with two audio players as an example, the two players can play the audio in pure audio or video respectively. A terminal with four audio players is similar to a terminal with two audio players, except that it has a better stereoscopic effect, since it can play audio from four different orientations.
In S101, the current spatial state of the terminal is obtained, which means that the current spatial orientation, motion situation, and other information of the terminal are determined, so as to determine what way the user uses the terminal. Generally, a user can use the terminal through roughly two terminal gestures, namely a vertical screen gesture and a horizontal screen gesture, in the vertical screen gesture, because audio players of the terminal are arranged at the top and the bottom, the audio channels are not needed to be distinguished, the same audio can be played through the two audio players, or one of the two audio players is selected to play the audio; if the user uses the terminal in the landscape mode, there is a necessity of channel differentiation, and the user can play different channels, i.e. a left channel and a right channel, through the audio players at the top and the bottom of the terminal to play the audio to be played. Whereas if the terminal has four audio players as shown in fig. 3, which are usually two in a group playing audio of one channel, in the terminal configuration of fig. 3, the terminal has audio players at different positions in the lateral direction, regardless of whether it is landscape or portrait, so that the channels can be distinguished.
In S102, after determining the current spatial state of the terminal, the audio player information corresponding to the played audio may be determined according to the spatial state. The audio player information may include channel selection of the audio player, and information such as playing volume of the audio player. In particular, channel selection is to select which one or more audio players to play the audio of the corresponding channel. Generally, an audio can be divided into at least a left channel and a right channel, the left channel and the right channel play different audios, and the different audios need to be played through the current space state of the terminal, when a user uses the terminal, in the horizontal screen state, the audio player located on the left side plays the audio of the left channel, the audio player located on the right side plays the audio of the right channel, and according to the change of the space state of the terminal, the selection process is adjusted correspondingly.
In some embodiments, obtaining the current spatial state of the terminal may include:
acquiring current motion data of the terminal through a motion sensor arranged in the terminal;
and determining the current space state of the terminal according to the current motion data of the terminal.
The motion sensor built in the terminal may include at least one of a gyroscope sensor and an acceleration sensor. Referring to fig. 4, fig. 4 shows a three-dimensional coordinate system of the terminal, wherein the x-axis and the y-axis are parallel to the plane of the display screen of the terminal, the x-axis is the width direction of the terminal, the y-axis is the length direction of the terminal, and the z-axis is perpendicular to the terminal screen, and the forward direction thereof is the direction facing the user, i.e. the display direction facing the terminal screen. The above definition of the x, y, and z axes is only an optional solution, and the corresponding three-dimensional coordinate system may be defined in any other manner, and this embodiment does not limit this, but only takes this as an example to perform the corresponding description.
The gyroscope and the acceleration sensor are used for detecting the motion state of the terminal, for example, the gyroscope sensor can measure information such as rotation angular velocity and angle of the terminal, and the transverse screen direction of the terminal can be judged according to the direction of the angular velocity or the angle information, wherein the transverse screen direction takes the bottom of the terminal as a reference, and when the top of the terminal is positioned on the left side of the bottom of the terminal in the transverse screen state, the terminal is considered to be transversely screened leftwards; when the top of the terminal is located at the right side of the bottom of the terminal in the landscape state, it is considered to be landscape to the right.
In some embodiments, when the motion sensor includes a gyroscope sensor, acquiring the current motion data of the terminal through the motion sensor built in the terminal may include: acquiring a rotation angle of the terminal based on an initial state through a gyro sensor; determining the current space state of the terminal according to the current motion data of the terminal comprises the following steps: and determining the attitude information in the current space state of the terminal according to the rotation angle. The explanation is made with four audio player terminals, and the three-dimensional coordinate system refers to fig. 4. When the terminal normally displays in a vertical screen mode, as shown in fig. 5, the terminal is kept in a static state, the angle of the gyroscope in a reference state is 0 ° according to the calibrated gyroscope data, and then the audio channels are configured through the analog switches, the left channel of the audio is output from the audio players 1 and 4, and the right channel of the audio is output from the audio players 2 and 3. When the panel is switched to landscape display by rotating the panel to the left, as shown in fig. 6, the gyro Z-axis angle data is rotated 90 ° counterclockwise, and the audio channels are configured by the analog switches, the left channel of the audio is output from the audio players 1 and 2, and the right channel of the audio is output from the audio players 3 and 4. When the panel is switched to the landscape display by rotating it to the right as shown in fig. 7, the gyro Z-axis angle data is now rotated 90 ° clockwise, and the audio channels are configured by the analog switches, the left channel of the audio is output from the audio players 3 and 4, and the right channel of the audio is output from the audio players 1 and 2. In general, the calibration of the gyroscope is based on the gyroscope angle data when the terminal is displayed on the vertical screen, that is, the direction shown in fig. 5, but of course, other display directions may be used as the reference calibration directions.
In some embodiments, determining, according to the current spatial state of the terminal, audio player information corresponding to each of the channels of the audio to be played may include: and according to the attitude information in the current space state of the terminal, determining an audio player corresponding to the sound channel of the audio to be played from the audio players on the terminal.
In some embodiments, when the motion sensor includes an acceleration sensor, acquiring the current motion data of the terminal through a motion sensor built in the terminal may include: acquiring the motion acceleration of the terminal based on the initial state through an acceleration sensor; determining the current space state of the terminal according to the current motion data of the terminal comprises the following steps: and determining the motion information in the current space state of the terminal according to the motion acceleration. Determining, according to the current spatial state of the terminal, audio player information corresponding to each channel of the audio to be played may include: and determining the volume adjustment information of the terminal audio player according to the motion information in the current space state of the terminal. The acceleration sensor can then measure the linear acceleration of the terminal. The acceleration sensor can measure acceleration values of an object in three directions based on a micro-mechanical structure that converts acceleration into a change in capacitance value. Generally, the acceleration sensor does not distinguish between the acceleration of gravity and the acceleration of motion, that is, the measured acceleration value is a composite value of the two. Taking the z-axis as an example, in the initial state, the acceleration value of the z-axis is the decomposition value of the gravitational acceleration in the z-axis, Az ═ g × cos θ, and θ represents the included angle between the plane of the mobile phone and the horizontal plane. From rest to motion, the acceleration value of the Z axis is the resultant of the gravitational acceleration Az and the motion acceleration a (t), a ═ g × cos θ + a (t). The measured values of the Z-axis acceleration in the motion state and the static state are subtracted by A-Az to obtain the value a (t) of the motion acceleration. Defining the Z-axis positive direction in the three-dimensional coordinate system as the direction facing the user, and when the terminal is close to the user, the value of the motion acceleration is positive, as shown in FIG. 8; when the terminal is far from the user, the value of the acceleration of motion is negative as shown in fig. 9. The Z-axis relative displacement can be calculated by quadratic integration by using the motion acceleration value of the Z-axis
Where a (t) is the Z-axis motion acceleration value. If a (t)>And 0, judging that the user holds the terminal close, reducing the volume of the system, and judging the level of reduction of the volume according to the calculated relative displacement Z (t). Such asFruit a (t)<And 0, judging that the user holds the terminal far away, the system needs to increase the volume, and judging the level of the volume increase according to the calculated relative displacement Z (t). The initial state of the terminal may specifically include that the terminal is in a static state. The stationary state is a state in which the terminal is not displaced within a certain time, and may be determined in real time according to a motion condition of the terminal, for example, if the terminal moves from a stationary point a to a stationary point b, for the point b, the initial state is a stationary state of the terminal at the point a; and if the terminal is stationary at point b for a period of time and then moves to point c, then the initial state for point c is the state stationary at point b.
In some embodiments, determining the volume change information of the audio player of the terminal according to the motion information in the current spatial state of the terminal may include: determining the displacement condition of the terminal relative to a user according to the motion information in the current space state of the terminal; and determining the volume adjustment information of the audio player on the terminal according to the displacement condition. The motion information of the terminal is mainly used for determining the relative displacement between the terminal and the user so as to provide the optimal hearing experience for the user; when the user is far away from the terminal, the sound heard by the user is reduced by the audio played at the original volume, so that the volume of the terminal is increased for the user experience to adapt to the far-away user; when the user approaches the terminal, the sound heard by the user becomes larger according to the audio played at the original volume, and the volume of the terminal can be reduced in order to protect the hearing of the user.
The embodiment provides an audio playing method, which is applied to a terminal with at least two audio players, and determines audio player information corresponding to a sound channel of an audio to be played respectively according to the current space state of the terminal by acquiring the current space state of the terminal; and playing the audio from the corresponding audio player. Therefore, the channel information corresponding to the audio to be played is determined by the current space state of the terminal, and then the audio of the corresponding channel is played by the corresponding audio player in the direction of the channel, so that the self-adaptive adjustment of the audio playing channel is realized, and the user experience is improved.

The rotation direction may be determined according to the direction of the angular velocity of the gyroscope, and the rotation angle may be determined according to the integrated value of the angular velocity. In order to ensure the detection effect, an error range of +/-5 degrees can be set, and the error range is adjusted according to the required detection sensitivity effect.

In order to ensure the detection effect, a detection threshold value can be set, and the threshold value is adjusted according to the required detection sensitivity effect.
And S1104, when the delta Az is less than 0, judging that the user holds the terminal far away, the system needs to increase the volume, and judging the number of stages of volume increase according to the relative displacement calculated by quadratic integration. In order to ensure the detection effect, a detection threshold value can be set, and the threshold value is adjusted according to the required detection sensitivity effect.

a playing confirmation module 122, configured to determine, according to a current spatial state of the terminal, audio player information corresponding to each of the channels of the audio to be played;
and the audio playing module 123 is configured to play audio from a corresponding audio player.
The current space state of the terminal is obtained, and the information such as the current space orientation and the motion situation of the terminal is determined to judge the way in which the user uses the terminal. Generally, a user can use the terminal through roughly two terminal gestures, namely a vertical screen gesture and a horizontal screen gesture, in the vertical screen gesture, because audio players of the terminal are arranged at the top and the bottom, the audio channels are not needed to be distinguished, the same audio can be played through the two audio players, or one of the two audio players is selected to play the audio; if the user uses the terminal in the landscape mode, there is a necessity of channel differentiation, and the user can play different channels, i.e. a left channel and a right channel, through the audio players at the top and the bottom of the terminal to play the audio to be played. Whereas if the terminal has four audio players as shown in fig. 3, which are usually two in a group playing audio of one channel, in the terminal configuration of fig. 3, the terminal has audio players at different positions in the lateral direction, regardless of whether it is landscape or portrait, so that the channels can be distinguished.
After the current space state of the terminal is determined, the audio player information corresponding to the played audio can be determined according to the space state. The audio player information may include channel selection of the audio player, and information such as playing volume of the audio player. In particular, channel selection is to select which one or more audio players to play the audio of the corresponding channel. Generally, an audio can be divided into at least a left channel and a right channel, the left channel and the right channel play different audios, and the different audios need to be played through the current space state of the terminal, when a user uses the terminal, in the horizontal screen state, the audio player located on the left side plays the audio of the left channel, the audio player located on the right side plays the audio of the right channel, and according to the change of the space state of the terminal, the selection process is adjusted correspondingly.
In some embodiments, obtaining the current spatial state of the terminal may include:
acquiring current motion data of the terminal through a motion sensor arranged in the terminal;
and determining the current space state of the terminal according to the current motion data of the terminal.
The motion sensor built in the terminal may include at least one of a gyroscope sensor and an acceleration sensor. Referring to fig. 4, fig. 4 shows a three-dimensional coordinate system of the terminal, wherein the x-axis and the y-axis are parallel to the plane of the display screen of the terminal, the x-axis is the width direction of the terminal, the y-axis is the length direction of the terminal, and the z-axis is perpendicular to the terminal screen, and the forward direction thereof is the direction facing the user, i.e. the display direction facing the terminal screen. The above definition of the x, y, and z axes is only an optional solution, and the corresponding three-dimensional coordinate system may be defined in any other manner, and this embodiment does not limit this, but only takes this as an example to perform the corresponding description.
The gyroscope and the acceleration sensor are used for detecting the motion state of the terminal, for example, the gyroscope sensor can measure information such as rotation angular velocity and angle of the terminal, and the transverse screen direction of the terminal can be judged according to the direction of the angular velocity or the angle information, wherein the transverse screen direction takes the bottom of the terminal as a reference, and when the top of the terminal is positioned on the left side of the bottom of the terminal in the transverse screen state, the terminal is considered to be transversely screened leftwards; when the top of the terminal is located at the right side of the bottom of the terminal in the landscape state, it is considered to be landscape to the right.
In some embodiments, when the motion sensor includes a gyroscope sensor, acquiring the current motion data of the terminal through the motion sensor built in the terminal may include: acquiring a rotation angle of the terminal based on an initial state through a gyro sensor; determining the current space state of the terminal according to the current motion data of the terminal comprises the following steps: and determining the attitude information in the current space state of the terminal according to the rotation angle. The explanation is made with four audio player terminals, and the three-dimensional coordinate system refers to fig. 4. When the terminal normally displays in a vertical screen mode, as shown in fig. 5, the terminal is kept in a static state, the angle of the gyroscope in a reference state is 0 ° according to the calibrated gyroscope data, and then the audio channels are configured through the analog switches, the left channel of the audio is output from the audio players 1 and 4, and the right channel of the audio is output from the audio players 2 and 3. When the panel is switched to landscape display by rotating the panel to the left, as shown in fig. 6, the gyro Z-axis angle data is rotated 90 ° counterclockwise, and the audio channels are configured by the analog switches, the left channel of the audio is output from the audio players 1 and 2, and the right channel of the audio is output from the audio players 3 and 4. When the panel is switched to the landscape display by rotating it to the right as shown in fig. 7, the gyro Z-axis angle data is now rotated 90 ° clockwise, and the audio channels are configured by the analog switches, the left channel of the audio is output from the audio players 3 and 4, and the right channel of the audio is output from the audio players 1 and 2. In general, the calibration of the gyroscope is based on the gyroscope angle data when the terminal is displayed on the vertical screen, that is, the direction shown in fig. 5, but of course, other display directions may be used as the reference calibration directions.
In some embodiments, determining, according to the current spatial state of the terminal, audio player information corresponding to each of the channels of the audio to be played may include: and according to the attitude information in the current space state of the terminal, determining an audio player corresponding to the sound channel of the audio to be played from the audio players on the terminal.
In some embodiments, when the motion sensor includes an acceleration sensor, acquiring the current motion data of the terminal through a motion sensor built in the terminal may include: acquiring the motion acceleration of the terminal based on the initial state through an acceleration sensor; determining the current space state of the terminal according to the current motion data of the terminal comprises the following steps: and determining the motion information in the current space state of the terminal according to the motion acceleration. Determining, according to the current spatial state of the terminal, audio player information corresponding to each channel of the audio to be played may include: and determining the volume adjustment information of the terminal audio player according to the motion information in the current space state of the terminal. The acceleration sensor can then measure the linear acceleration of the terminal. The acceleration sensor can measure acceleration values of an object in three directions based on a micro-mechanical structure that converts acceleration into a change in capacitance value. Generally, the acceleration sensor does not distinguish between the acceleration of gravity and the acceleration of motion, that is, the measured acceleration value is a composite value of the two. Taking the z-axis as an example, in the initial state, the acceleration value of the z-axis is the decomposition value of the gravitational acceleration in the z-axis, Az ═ g × cos θ, and θ represents the included angle between the plane of the mobile phone and the horizontal plane. From rest to motion, the acceleration value of the Z axis is the resultant of the gravitational acceleration Az and the motion acceleration a (t), a ═ g × cos θ + a (t). The measured values of the Z-axis acceleration in the motion state and the static state are subtracted by A-Az to obtain the value a (t) of the motion acceleration. Defining the Z-axis positive direction in the three-dimensional coordinate system as the direction facing the user, and when the terminal is close to the user, the value of the motion acceleration is positive, as shown in FIG. 8; when the terminal is far from the user, the value of the acceleration of motion is negative as shown in fig. 9. The Z-axis relative displacement can be calculated by quadratic integration by using the motion acceleration value of the Z-axis
Wherein a (t) is the Z-axis motion plusThe speed value. If a (t)>And 0, judging that the user holds the terminal close, reducing the volume of the system, and judging the level of reduction of the volume according to the calculated relative displacement Z (t). If a (t)<And 0, judging that the user holds the terminal far away, the system needs to increase the volume, and judging the level of the volume increase according to the calculated relative displacement Z (t). The initial state of the terminal may specifically include that the terminal is in a static state. The stationary state is a state in which the terminal is not displaced within a certain time, and may be determined in real time according to a motion condition of the terminal, for example, if the terminal moves from a stationary point a to a stationary point b, for the point b, the initial state is a stationary state of the terminal at the point a; and if the terminal is stationary at point b for a period of time and then moves to point c, then the initial state for point c is the state stationary at point b.
In some embodiments, determining the volume change information of the audio player of the terminal according to the motion information in the current spatial state of the terminal may include: determining the displacement condition of the terminal relative to a user according to the motion information in the current space state of the terminal; and determining the volume adjustment information of the audio player on the terminal according to the displacement condition. The motion information of the terminal is mainly used for determining the relative displacement between the terminal and the user so as to provide the optimal hearing experience for the user; when the user is far away from the terminal, the sound heard by the user is reduced by the audio played at the original volume, so that the volume of the terminal is increased for the user experience to adapt to the far-away user; when the user approaches the terminal, the sound heard by the user becomes larger according to the audio played at the original volume, and the volume of the terminal can be reduced in order to protect the hearing of the user.
The embodiment provides an audio playing device, which is applied to a terminal with at least two audio players, and determines audio player information corresponding to each channel of audio to be played according to the current space state of the terminal by acquiring the current space state of the terminal; and playing the audio from the corresponding audio player.
