The terminal can be provided with an audio playing component, a processor, a distance measuring sensor, the audio playing component can be used for playing audio data, for example, a loudspeaker, the processor can be used for determining a target volume value corresponding to the current space environment according to the space size of the space environment, the distance measuring sensor can be used for measuring the distance between the distance measuring sensor and the edge point of the space environment, in addition, the distance measuring sensor can also be an external distance measuring sensor connected with the terminal, the terminal can obtain the distance detected by the distance measuring sensor, and further the space size of the space environment where the terminal is located is determined, wherein the external distance measuring sensor connected with the terminal can be connected with the terminal through a data line, can also be connected with the terminal through a Bluetooth component, and can also be connected with the terminal through a wifi (Wireless Fidelity) signal. In the embodiment of the invention, the distance measuring sensor and the terminal are always in the same space environment. The terminal may further include a Positioning component, and the Positioning component may be configured to detect a current location of the terminal, for example, the Positioning component may be a Global Positioning System (GPS).
The process flow shown in fig. 1 will be described in detail below with reference to specific embodiments, and the contents may be as follows:
step 101, detecting the space size of the space environment where the terminal is located through a ranging sensor.
The distance measuring sensor may be a sensor for detecting a distance between two points, and may be, for example, an infrared distance measuring sensor, an ultrasonic distance measuring sensor, or the like.
In implementation, an application program for playing audio data (for example, an application program for playing a song or an application program for playing a video) may be installed in the terminal, when the terminal opens the application program for playing audio data, the corresponding automatic volume adjustment function may be started, and in a state that the automatic volume adjustment function is started, the terminal may detect the spatial size of the spatial environment where the terminal is located through the distance measurement sensor. Specifically, a detection trigger event may be pre-stored in the terminal, where the detection trigger event may be used to trigger the ranging sensor to start, that is, may be used to trigger the terminal to detect the spatial size of the spatial environment where the terminal is located through the ranging sensor. When the terminal detects that the preset trigger event occurs, the distance measuring sensor can be started, and then the space size of the space environment where the terminal is located is detected through the distance measuring sensor.
Optionally, the spatial dimension of the spatial environment may be an area of a plane parallel to the ground in the spatial environment (i.e., an area of a horizontal cross section in the spatial environment), or may be a volume of the spatial environment, where the horizontal cross section in the spatial environment may be a horizontal cross section where the distance measuring sensor is located, or may be a horizontal cross section where the distance measuring sensor is located farther from the ground.
Optionally, based on different preset detection trigger events, the processing manner of step 101 may be various, and several feasible processing manners are given below:
in the first mode, every time a preset detection period is reached, the space size of the space environment where the terminal is located is detected through the ranging sensor.
In implementation, a detection period can be preset in the terminal, and the terminal can control the distance measuring sensor to be turned on every preset detection period, detect the space size of the space environment where the terminal is located through the distance measuring sensor, turn off the distance measuring sensor after detection is finished, and turn on the distance measuring sensor again when the next detection period is finished, so as to detect the space size of the space environment where the terminal is currently located.
And in the second mode, when a detection instruction input by a user is received, the space size of the space environment where the terminal is located is detected through the distance measuring sensor.
In implementation, a key (which may be referred to as a detection key) for starting a detection space size is provided in the terminal, where the key may be a touch key or a mechanical key. When a user wants to enable the terminal to detect the space size of the current space environment, the detection key can be pressed, at the moment, the terminal can receive a detection instruction input by the user, and then the terminal can be triggered to detect the space size of the space environment where the terminal is located through the distance measuring sensor.
And in the third mode, when the position of the terminal is detected to be changed, the space size of the space environment where the terminal is located is detected through the ranging sensor.
In implementation, the terminal may detect the position of the terminal by using its own positioning component (e.g., a global positioning system), and when detecting that the position of the terminal changes, the terminal may be triggered to turn on the ranging sensor, and the spatial dimension of the spatial environment where the terminal is located may be detected by the ranging sensor. In addition, a position change amplitude threshold value can be preset in the terminal, and when the position change of the terminal reaches the preset position change amplitude threshold value, the space size of the space environment where the terminal is located is detected through the ranging sensor. For example, the preset position variation amplitude threshold may be a preset distance threshold, at time T, the terminal is at a position a, at time T (where T is greater than T), the terminal is detected at a position B, and if the distance between the position a and the position B is greater than the preset distance threshold, the terminal is triggered to detect the spatial size of the spatial environment where the terminal is located through the ranging sensor.
Optionally, the terminal may detect the spatial size of the spatial environment where the terminal is located through the ranging sensor in the process of playing the audio data, and accordingly, the processing procedure in the first mode may be as follows: detecting the space size of the space environment where the terminal is located through a distance measuring sensor every preset detection period in the process of playing the audio data by the terminal; the processing procedure of the second mode can be as follows: in the process of playing audio data by the terminal, when a detection instruction input by a user is received, detecting the space size of the space environment where the terminal is located through a distance measuring sensor; the processing procedure of the third mode can be as follows: in the process of playing audio data by the terminal, when the position of the terminal is detected to be changed, the space size of the space environment where the terminal is located is detected through the distance measuring sensor.
In implementation, the terminal may further detect whether the terminal is currently playing audio data, and the terminal may detect the spatial size of the spatial environment where the terminal is located through the ranging sensor based on a preset detection period on the premise of playing the audio data, or detect the spatial size of the spatial environment where the terminal is located through the ranging sensor when receiving a detection instruction input by a user in the process of playing the audio data by the terminal, or detect the spatial size of the spatial environment where the terminal is located through the ranging sensor when detecting that the position of the terminal changes in the process of playing the audio data by the terminal. That is to say, in the process of playing audio data at the terminal, the terminal detects the spatial dimension of the spatial environment where the terminal is located through the ranging sensor, so that the spatial dimension of the spatial environment can be prevented from being detected when the terminal does not play audio data, and therefore, the electric quantity can be saved.
Optionally, for the case that the spatial dimension of the spatial environment is the area of the horizontal cross section in the spatial environment, the processing procedure of step 101 may be as follows: detecting the distances between the edge points of the horizontal section in a plurality of different directions and the distance measuring sensor by the distance measuring sensor; and determining the area of the horizontal section according to the distance between the edge point of the horizontal section in a plurality of different directions and the ranging sensor and the included angle between each pair of adjacent directions.
In an implementation, whenever a preset detection trigger event is detected to occur, the ranging sensor may rotate in a preset direction (for example, clockwise or counterclockwise) in a horizontal section in the space environment, after each rotation by a preset angle, the terminal may measure a distance between an edge point of the horizontal section in the direction and the ranging sensor through the ranging sensor, and after the rotation by 360 degrees, the terminal may control the ranging sensor to turn off, at this time, the terminal may obtain distances between the edge point of the horizontal section in a plurality of different directions and the ranging sensor, where the edge point may be a position point where an object (the object may be an object, may be an animal, or may be a person) closest to the ranging sensor in the direction is located. For example, the preset angle is 45 degrees, each time a preset detection trigger event is detected, the terminal may detect the distance between the edge point of the horizontal section in the current direction and the ranging sensor through the ranging sensor, then rotate 45 degrees counterclockwise, then the terminal may detect the distance between the edge point of the horizontal section in the direction and the ranging sensor through the ranging sensor, and so on, and finally the terminal may obtain the distances between the edge point of the horizontal section in six different directions and the ranging sensor, as shown in fig. 2.
After the terminal obtains the distances between the edge points of the horizontal section in a plurality of different directions and the ranging sensor, the area of the horizontal section can be estimated. Specifically, the swept area of the distance measuring sensor at each rotation can be obtained by the distance between the edge point of the horizontal cross section in the two directions and the distance measuring sensor and the included angle between the pair of adjacent directions (i.e. a preset angle, such as 45 degrees), that is, a line segment whose length is the distance between the edge point of the horizontal cross section in the two directions and the distance measuring sensor can be used as the two sides of the triangle, the preset angle is the included angle between the two sides of the triangle, the terminal can calculate the area of the triangle according to the length of the two sides and the included angle between the two sides, and then, the area of the triangle can be used as the area of the area, and so on, the area of the horizontal cross section between each pair of adjacent directions can be calculated, and then, the area of each area is added to obtain the.
For example, as shown in fig. 3, a distance between an edge point of the horizontal cross section in the direction 1 and the ranging sensor is a, and a distance between an edge point of the horizontal cross section in the direction 2 and the ranging sensor is b, where the directions 1 and 2 are two adjacent directions, and a preset included angle is a, the terminal may calculate the length c of the third side according to formula (1), and further, may calculate the area S of the triangle according to formula (2).
S＝p(p-a)(p-b)(p-c) (2)
Where p is half the circumference. The terminal may obtain the area of each triangle according to the above method, and then add them to approximately obtain the area of the horizontal section. In addition, for the area of the first region in fig. 3, the obtained area of the triangle is the area of the region, and for the area of the second region in fig. 3, the area of the triangle calculated in this way is the approximate area of the corresponding second region.
And 102, determining a target volume value corresponding to the space size of the space environment where the terminal is located according to the corresponding relation between the pre-stored space size and the volume value.
In an implementation, a correspondence between the spatial size and the volume value may be stored in the terminal in advance, and each time the spatial size of the spatial environment in which the terminal is located is obtained, the spatial size corresponding volume value (i.e., the target volume value) of the spatial environment in which the terminal is located may be determined in the correspondence. Specifically, the terminal may store a correspondence table of the space size and the volume value in advance, as shown in table 1, a difference between the space sizes in the correspondence table may be set to be small, so that the target volume value may be accurately obtained for any space size, and in addition, when the correspondence table does not include the space size of the space environment where the terminal is located, the volume value corresponding to the space size closest to the space size of the space environment where the terminal is located in the correspondence table may be used as the target volume value. In addition, the space size in the correspondence table may also be a space size range, that is, the terminal may determine, according to a correspondence between a space size range and a volume value stored in advance, a target volume value corresponding to a space size range to which the space size of the space environment in which the terminal is located belongs.
TABLE 1
| Size of space | Volume value |
| 3 | 10 |
| 4 | 13 |
| … | … |
| 20 | 27 |
Optionally, a function of the volume and the spatial size may also be stored in the terminal in advance, and accordingly, the processing procedure of step 102 may be as follows: and calculating a target volume value corresponding to the space size of the space environment where the terminal is located according to the pre-stored independent variable as the space size and the dependent variable as the function of the volume value.
In an implementation, the terminal may store in advance a function V ═ f (Z) in which an argument is a space size (the space size may be represented by Z) and a dependent variable is a volume value (the volume value may be represented by V), where the function V ═ f (Z) may be as shown in function (3), and after the terminal detects the space size of the space environment where the terminal is located, a target volume value corresponding to the space size may be calculated by function (3).
And 103, adjusting the volume of the terminal to a target volume value.
In implementation, after the terminal obtains the target volume value, the volume value of the terminal may be adjusted to the target volume value, that is, if the terminal is playing the audio data, the terminal may play the audio data based on the volume value corresponding to the space size of the space environment where the terminal is located.
In addition, the terminal can also adjust the sound effect type corresponding to the space size of the current space environment according to the space size of the space environment where the terminal is located, and can also provide a space size external-adjusting interface so as to enable other equipment to call the space size of the space environment where the terminal is located, which is detected by the terminal.
In the embodiment of the invention, the terminal can measure the space size of the space environment where the terminal is located through the ranging sensor, further, the target volume value corresponding to the space environment where the terminal is currently located can be determined according to the corresponding relation between the pre-stored size of the space environment and the volume value, and finally, the volume of the terminal is adjusted to be the target volume value.
