Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
To there being volume control inconvenient in current earphone, reach the technical problem that the required volume speed of user is slow, this application embodiment provides a solution, and the basic thinking is: firstly, carrying out primary coarse adjustment on the volume of the earphone according to an environment noise signal outside the earphone, quickly adjusting the volume of the earphone to the volume adaptive to an external environment, and then carrying out secondary fine adjustment on the volume after the primary adjustment through a current head action signal of a user generated by the head action of the user to achieve the volume required by the user; according to the volume adjusting method, the volume of the earphone can be automatically adjusted without manual operation of a user, and accurate and rapid adjustment of the volume of the earphone can be achieved through a mode of combining primary coarse adjustment and secondary fine adjustment.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a volume adjustment method provided by an example in the present application, which is described below with reference to fig. 1, and the volume adjustment method includes:
s101: acquiring an environment noise signal outside the earphone, and primarily adjusting the volume of the earphone according to the environment noise signal to acquire the volume adaptive to the external environment;
s102: and acquiring a current head action signal of the user generated by the head action of the user, and carrying out secondary adjustment on the volume of the primarily adjusted earphone according to the current head action signal of the user so as to obtain the volume meeting the requirements of the user.
The method provided by the embodiment can be applied to earphones, which can be headphones, in-ear earphones and the like. The earphone can be provided with a microphone and can acquire an environmental noise signal of the current environment where the earphone is located; the earphone can also be provided with a sensor which can be used for collecting the current head action signal of the user generated by the head action of the user. It is worth mentioning that one or more different types of sensors may be provided on the headset. When a user wears the earphone, the user may be in different external environments, and for the external environments with different noises, the user needs to readjust the volume of the earphone after wearing the earphone each time.
In this embodiment, a microphone may be disposed on the earphone to collect external environmental noise, and after collecting an external environmental noise signal of the earphone, the earphone primarily adjusts the volume of the earphone according to the environmental noise signal to obtain the volume adapted to the external environment. According to the environment noise signal, the earphone firstly carries out coarse adjustment on the volume of the earphone, and the volume of the earphone is adjusted to the volume which can be heard by the user and can eliminate the interference of the external environment noise at one time.
Optionally, superimposing a preset decibel value on the decibel value of the environmental noise signal to serve as an initial tuning decibel value; and adjusting the current decibel value of the earphone volume to the initially adjusted decibel value to obtain the volume adaptive to the external environment. Regarding obtaining the volume adapted to the external environment, it should be noted herein that after a person wears the headset, the decibel value of the external environment noise transmitted to the ear of the person is reduced due to the shielding of the headset itself, and therefore, the initial decibel value here should be smaller than the decibel value of the external environment noise, so that the user can hear the audio content inside the headset. It should be noted that the preset decibel value is a fixed value set in advance inside the earphone, and the preset decibel value may be a fixed value that a manufacturer collects different noise environments, and experimental data of different users is set in a memory inside the earphone before the earphone leaves a factory, or may be a fixed value that the preset decibel value is modified according to personal use habits after the user purchases the earphone, for example, a touch display screen interacting with the user is provided on the earphone, the user sends a modification instruction through the touch display screen, a human-computer interaction interface can be displayed on the display screen, and the user can modify the preset decibel value by operating modification options on the interaction interface.
In the above embodiment, the decibel value of the environmental noise signal may be obtained by collecting the decibel value corresponding to each unit time within the specified time period and averaging all the collected decibel values to obtain an average decibel value, which is used as the decibel value of the environmental noise signal, or may be obtained by collecting the decibel value corresponding to each unit time within the specified time period and selecting the maximum value or the minimum value of all the decibel values as the decibel value of the environmental noise signal.
In the above optional embodiment, in an actual use process of the headset, if the headset is used each time, the volume decibel value used when the headset is turned off is automatically recorded, when the user wears the headset next time, the initial volume of the headset automatically calls the volume decibel value when the headset is turned off last time, and in this case, the following three situations may occur between the initial volume of the headset and the current volume of the headset:
firstly, when the current decibel value of the earphone is greater than the initially adjusted decibel value, namely the current decibel value of the earphone is far higher than the external environmental noise decibel value, the volume of the earphone needs to be reduced, and the earphone automatically reduces the volume to the initially adjusted decibel value;
secondly, when the current decibel value of the earphone is smaller than the initially adjusted decibel value, namely the current decibel value of the earphone is lower than the external ambient noise decibel value, the volume of the earphone needs to be increased, and the earphone automatically increases the volume of the earphone to the initially adjusted decibel value;
thirdly, when the initial volume decibel value is larger than the maximum volume decibel value of the earphone, namely the external environment noise is too large, directly adjusting the volume of the earphone to the maximum volume decibel value of the earphone.
After the earphone volume is preliminarily adjusted, the preliminarily adjusted earphone volume is secondarily adjusted according to the current head action signal of the user so as to obtain the volume meeting the requirements of the user. After the earphone is preliminarily adjusted, the user can judge the earphone volume after preliminary adjustment, if the volume automatically adjusted by the user cannot meet the requirement of the user on the volume, the earphone volume can be micro-adjusted again, and the user can generate a current head action signal through head action to micro-adjust the earphone volume so as to reach the satisfactory volume of the user.
In this embodiment, the head motion of the user may be nodding, tilting, left nodding, right nodding, etc. When the head of the user acts, the sensor on the earphone collects the head action data of the user and converts the head action data of the user into a current head action signal of the user corresponding to the head action.
In the above embodiment, the obtaining of the user current head motion signal generated by the user head motion may be: after the head of a user sends out a volume adjustment action, a first sensor arranged at the top of a head-wearing main body of the earphone and a second sensor arranged on an earphone module at one side of the earphone are used for collecting the current coordinate value of the earphone; and determining the current head action signal of the user according to the current coordinate values of the earphones acquired by the first sensor and the second sensor.
In the embodiment, the two sensors are used for collecting the coordinate values of the earphones in real time, and the current head action signal of the user is determined through the change of the current coordinate values of the earphones. For example, when the head is noded, the earphone generates a forward motion and a downward motion, and accordingly, the coordinate values acquired by the sensor generate corresponding displacements on the forward and downward spatial axes, so that the motion of the user can be determined through the change of the coordinate values, and further the current head motion signal of the user is determined through the current coordinate values of the earphone.
In the above or following embodiments of the present application, before the head of the user sends out a volume adjustment action, whether the headset is in a standard wearing posture is determined according to the current coordinate values of the headset acquired by the first sensor and the second sensor; if not, outputting a prompt tone to prompt the user to adjust the earphone to the standard wearing posture. Under the condition that the standard wearing posture is judged to be negative, the user can be prompted to adjust the earphone to the standard wearing posture through other modes such as light flashing and the like.
It should be noted that the standard wearing posture refers to a posture in which the head is in a natural straightened state after the user normally wears the headphones. The method for judging whether the earphone is in the standard wearing posture can be used for determining the standard wearing posture by current coordinate values of the earphone collected by the first sensor and the second sensor through setting a certain threshold value as long as the earphone is in the threshold value range, and errors caused by head inclination or slight shaking of a user when the user wears the earphone every time can be eliminated through setting the threshold value. In some special cases, the head of an individual user is also inclined in a natural state, and the head of the user is taken as a standard wearing posture in the natural inclined state. After the earphone is judged to be in the standard wearing posture, the current coordinate values of the earphone collected by the first sensor and the second sensor can be restored to the initial values.
Optionally, the secondary adjustment of the primarily adjusted earphone volume by using the current head motion signal of the user may be: matching the current head action signal of the user in a mapping relation between a preset volume control instruction and the current head action signal of the user to obtain a volume control instruction in matching; and adjusting the volume of the earphone according to the volume control instruction in the matching.
In the above embodiment, the current head action signal of the user and the volume control instruction have a one-to-one correspondence relationship, a mapping relationship between the current head action signal of the user and the volume control instruction is preset in a memory of the earphone, and after receiving the current head action signal of the user, the processor finds out the volume control instruction corresponding to the current head action signal of the user from the mapping relationship, and adjusts the volume of the earphone.
In an alternative embodiment, the left nodding signal corresponds to a turned up volume and the right nodding signal corresponds to a turned down volume. The secondary adjustment of the earphone volume after the initial adjustment by using the current head motion signal of the user includes the following two ways, the following two ways of adjusting the earphone volume are merely exemplary, and the ways of adjusting the earphone volume are not limited to the following two ways.
The first method is as follows: if the gesture action signal is a left nodding signal, the volume control instruction in the matching is the volume to be increased, and then secondary adjustment is carried out on the volume of the primarily adjusted earphone according to the volume control instruction in the matching, wherein the secondary adjustment comprises the following steps: increasing the volume of the primarily adjusted earphone according to the set volume step length;
the second method comprises the following steps: if the gesture action signal is a right nodding signal, the volume control instruction in the matching is turning down the volume, and the volume of the earphone is adjusted according to the volume control instruction in the matching, including: and reducing the volume of the earphone after the initial adjustment according to the set volume step length.
Obviously, in the above embodiment, the left nodding signal may correspond to the turning-down volume, and the right nodding signal may correspond to the turning-up volume. In essence, it is sufficient that the volume-down and volume-up correspond to different current head movement signals of the user.
According to the embodiment of the application, the volume of the earphone is roughly adjusted preliminarily according to the ambient noise signal outside the earphone, the volume of the earphone is quickly adjusted to the volume which is in offsetting fit with the external environment, and then secondary fine adjustment is carried out on the volume after preliminary adjustment according to the current head action signal of a user generated by the head action of the user, so that the volume required by the user is achieved; according to the volume adjusting method, the volume of the earphone can be automatically adjusted without manual operation of a user, and accurate and rapid adjustment of the volume of the earphone can be achieved through a mode of combining primary coarse adjustment and secondary fine adjustment.
Fig. 2 is a flowchart illustrating a headset controlling related functions according to head movements according to an exemplary embodiment of the present application. The method for controlling volume adjustment by head movement and other functions of other earphones by head movement are exemplified in the following with reference to fig. 2.
In the present exemplary embodiment, first, the microphone collects an external environment noise signal, sets a proper volume in advance, and coarsely adjusts the volume of the earphone to obtain a volume suitable for the external environment. The method for primarily adjusting the earphone according to the external environment volume can superpose a preset decibel value on the decibel value of the environment noise signal to serve as an initially adjusted decibel value; and adjusting the current decibel value of the earphone volume to the initially adjusted decibel value.
And then, judging whether the earphone is in the standard wearing posture. When the earphone is judged to be in the standard wearing posture, the current coordinate values of the earphone collected by the first sensor 11 and the second sensor 12 are adjusted to be (0, 0, 0). The coordinate values in this embodiment are coordinates in a three-dimensional coordinate system. The following embodiment is merely an exemplary illustration of how to determine the current head motion signal of the user, and the manner of determining the gesture motion signal of the user is not limited to the following manner, nor in the following scenario.
After the earphone is in the standard wearing posture, the user generates a head action signal through head action. The current coordinate values of the earphones collected by the first sensor 11 are (X1, Y1, Z1), and the current coordinate values of the earphones collected by the second sensor 12 are (X2, Y2, Z2). At this time, the coordinate values acquired by the first sensor 11 and the second sensor 12 are the actual displacement amounts of the first sensor and the second sensor in the three spatial directions X, Y, Z.
Presetting that X1 and X2 are both greater than 0 when the head moves to the left side, and X1 and X2 are both less than 0 when the head moves to the right side; when the head moves forwards, Y1 and Y2 are both larger than 0, and when the head moves backwards, Y1 and Y2 are both smaller than 0; when the head moves upward, Z1 and Z2 are both greater than 0, and when the head moves backward, Z1 and Z2 are both less than 0.
When the current earphone coordinate values (X1, Y1, Z1) and the current earphone coordinate values (X2, Y2, Z2) satisfy the following conditions, the corresponding gesture motion signal of the user may be determined:
when Y1-Y2-0, X1 > X2 > 0, Z1 < Z2 < 0, and | X1|, | X2| are simultaneously greater than a first threshold, and | Z1|, | Z2| are simultaneously greater than a third threshold, determining that the current head motion signal of the user is a left nodding signal;
when Y1-Y2-0, X1-X2-0, Z1-Z2-0, and | X1|, | X2| are simultaneously greater than a first threshold, and | Z1|, | Z2| are simultaneously greater than a third threshold, determining that the current head motion signal of the user is a right nodding signal;
when X1 is equal to X2 is equal to 0, Y1 is greater than Y2 is greater than 0, Z1 is greater than Z2 and is less than 0, Y1 and Y2 are simultaneously greater than a second threshold, and Z1 and Z2 are simultaneously greater than a third threshold, determining that the current head motion signal of the user is a head-lowering signal;
and when X1 is equal to X2 is equal to 0, Y1 is less than Y2 is less than 0, Z1 is less than Z2 is less than 0, Y1 and Y2 are simultaneously greater than a second threshold, and Z1 and Z2 are simultaneously greater than a third threshold, determining that the current head motion signal of the user is a head raising signal.

In the above exemplary embodiment, the left nodding signal may correspond to a volume up function, the right nodding signal may correspond to a volume down function, the head up signal may correspond to a play start function or a confirmation function, and the head down signal may correspond to a play pause function. It is worth explaining that, in the embodiment of the application, different functions of the headset are controlled by different head movements, so that a user can thoroughly get rid of constraint of two hands, and better user experience is brought.
The explanation of value is, set up on the earphone and be equipped with first sensor and second sensor respectively on the earphone module of wearing main part top and one side, carry out the embodiment through two sensors and gather the earphone coordinate, through setting up first threshold value, second threshold value, third threshold value respectively in X, Y, Z upwards, in earphone action process, the displacement volume in X, Y, Z three directions that two sensors gathered all will reach first threshold value, second threshold value and third threshold value simultaneously, prevent to not trigger because of the slight shake production of head, improve the earphone and to the accuracy of head action judgement.
