It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
The disclosed embodiments are not limited to the embodiments shown in the drawings, but include modifications of configurations formed based on a manufacturing process. Thus, the regions illustrated in the figures have schematic properties, and the shapes of the regions shown in the figures illustrate specific shapes of regions of elements, but are not intended to be limiting.
In a first aspect, referring to fig. 1, an embodiment of the present disclosure provides a method for selecting a sound receiving unit, where the method is used for a terminal, where the terminal includes a plurality of sound generating units located at different positions of the terminal, and a plurality of sound receiving units (e.g., microphones) located at different positions of the terminal, and the method for selecting a sound receiving unit includes:
s101, determining that at least one sound generating unit is a working sound generating unit and at least one sound generating unit is a dormant sound generating unit.
The terminal (such as a mobile phone, a tablet and the like) is provided with a plurality of sounding units located at different positions, when different demands exist, the sounding units (namely, the working sounding units) at different positions are selected to work (namely, used for sounding), and other sounding units do not work to sound (namely, the sleeping sounding units).
Wherein, in order to make the sound of sound generating unit focus more, tone quality is better, generally can not all sound generating unit simultaneous workings. Therefore, in the process of one sound production, at least one sound production unit works, namely, serves as a working sound production unit, and at least one sound production unit does not work, namely, serves as a dormant sound production unit. For example, when talking on a hand, the sound generating unit near the ear can be selected to work so that the user can hear the sound more clearly; meanwhile, in order to make the sound of the sound generating units more focused and better in tone quality, the sound generating units at the upper and lower ends generally cannot work simultaneously.
And S102, according to the position of the mouth of the user, the position of the sound receiving unit and the position of the working sound generating unit, determining that at least one sound receiving unit is a main sound receiving unit (a main microphone), the signal received by the main sound receiving unit is a main audio signal, and the sound receiving units (auxiliary microphones) except the main sound receiving unit are closed or the signals received by the sound receiving units except the main sound receiving unit are used for carrying out optimization processing on the main audio signal.
Under the condition that the working sound generating unit is determined, the terminal (such as a mobile phone, a tablet and the like) determines that at least one sound receiving unit is the main sound receiving unit according to the obtained position of the mouth of the user and the position of all the sound receiving units in the terminal and the position of the working sound generating unit, namely at least one sound receiving unit is the main sound receiving unit and the other sound receiving units (if any) are non-main sound receiving units.
The signal received by the main sound receiving unit is a main audio signal, that is, the signal received by the main sound receiving unit is considered as the main audio signal, and the main audio signal mainly includes an original sound signal which is expected to be collected, such as a sound of a user speaking.
The non-main sound receiving unit can be closed, and signals for optimizing the main audio signals can be collected, so that definition, tone quality and the like of the main audio signals are improved. For example, the signal received by the non-primary sound receiving unit may include a noise signal for filtering and de-noising the primary audio signal to reduce noise in the primary audio signal; the signal received by the non-primary sound receiving unit may also include an echo (i.e. a sound emitted by the terminal's own sound emitting unit) for suppressing the echo in the primary audio signal.
In the embodiment of the disclosure, on the basis of determining the working sound generating unit, the position of the mouth of the user, and the position of the sound receiving unit are comprehensively considered to determine the position of the main sound receiving unit for receiving the main audio signal, so as to achieve the effects of obtaining better call sending tone quality and better echo suppression.
In some embodiments, the terminal further includes a screen, the sound generating unit is an excitation unit for exciting a region of the screen where the sound generating unit is located to generate sound by vibration, that is, the screen is driven by the exciter, the screen is used as a vibration body to generate sound by vibration, that is, the terminal has no receiver, and the excitation units are located at different positions behind the screen to generate sound at different positions of the screen.
In some embodiments, referring to fig. 2, determining at least one sound emitting unit as a working sound emitting unit (S101) comprises:
s1011, acquiring the corresponding position of the human ear on the terminal.
The terminal obtains the corresponding position of the human ear on the terminal, namely the position on the terminal closest to the human ear, such as the position where the human ear is contacted with the terminal.
Specifically, a plurality of pressure sensors are arranged in the screen to sense the pressure applied to the screen, and the area corresponding to the shape of the human ear in the area subjected to the pressure is determined as the corresponding position.
Of course, the corresponding position of the human ear on the terminal may be determined by other methods, for example, gravity sensing (i.e., the end farthest from the ground is the corresponding position of the human ear on the terminal) may be used, and the method may be flexibly selected according to the actual situation.
And S1012, selecting at least the sound generating unit closest to the corresponding position as a working sound generating unit.
After the position corresponding to the ear on the terminal is determined, the sound production unit closest to the position is selected as a working sound production unit, and meanwhile, other sound production units can be selected as working sound production units.
In order to make the sound of the sound generating unit more focused and have better sound quality, after the working sound generating unit closest to the corresponding position of the human ear on the terminal is determined, if other working sound generating units are selected, the selected working sound generating unit is generally close to the closest working sound generating unit.
The working sound production unit is determined according to the corresponding position of the human ear on the terminal, so that the sound production unit closest to the human ear can work, namely, the terminal position closest to the human ear produces sound, and therefore the energy of a sound signal received by the human ear can be ensured, namely, the sound can be clearly heard in the general sense. And some sounding units far away from the position do not work, so that people not holding the terminal can not clearly hear the sound, and conversation privacy can be guaranteed.
In some embodiments, referring to fig. 3, determining at least one sound receiving unit as a primary sound receiving unit based on the user' S mouth position, sound receiving unit position, and position of the working sound emitting unit (S102) comprises:
and S1021, determining the position of the mouth of the user, and determining at least one sound receiving unit as a candidate sound receiving unit according to the relative position of the mouth of the user and the sound receiving unit.
In the case where the terminal determines the mouth position of the user, that is, the mouth position of the person holding the terminal at present, in the case where the mouth position of the user is determined, the quality of the collected sound can be enhanced by using a method of collecting sound using sound receiving units as close to the mouth position as possible, and thus at least one sound receiving unit can be determined as a candidate sound receiving unit according to the determined mouth position.
Since the influence of echo and noise is also taken into consideration, the sound receiving unit determined according to the relative position of the user's mouth and the sound receiving unit is only a candidate sound receiving unit, and further selection is required to reduce the influence of echo and noise, and the main sound receiving unit, that is, the sound receiving unit for receiving the main audio signal can be finally determined.
And S1022, determining the main sound receiving unit according to the position of the candidate sound receiving unit and the position of the working sound generating unit.
After obtaining the positions of the candidate sound receiving units, the terminal determines the main sound receiving unit according to the positions of the candidate sound receiving units and by combining the positions of all the sound generating units, namely the positions of the working sound generating units and the positions of the non-working sound generating units.
By taking into account the position of the sound emitting unit and the position of the candidate sound receiving unit, the influence of the sound generated by the operation of the sound emitting unit on the quality of the sound collected by the operating sound receiving unit, i.e., the main sound receiving unit, can be reduced, i.e., the sound emitted by the operation of the sound emitting unit can be collected by the sound receiving unit, which is obviously desirable to avoid, and thus can be reduced by increasing the distance between the operating sound emitting unit and the operating sound receiving unit, i.e., the main sound receiving unit.
In some embodiments, referring to fig. 4, determining the user 'S mouth position, the partial sound receiving unit being a candidate sound receiving unit according to the user' S mouth position (S1021) comprises:
s10211, acquiring position data, wherein the position data comprises human ear position data and finger position data.
The terminal obtains the required position data, including but not limited to human ear position data and finger position data. Wherein the ear position data is position information of the ear relative to the terminal for listening in the using process; the left ear or the right ear close to the terminal can be reflected, so that the left hand or the right hand of the holding hand holding the terminal can be judged in an auxiliary manner, namely according to habits of most users, when the left ear close to the terminal is close to the terminal, the holding hand holding the terminal is most likely to be the left hand; on the contrary, when the right ear is close to the terminal, the holding hand currently holding the terminal is most likely to be the right hand. The finger position data is the position of the hand holding the terminal relative to the terminal, and the finger position data can be combined with the information of whether the current holding is the left hand or the right hand, so that the current holding posture, such as horizontal holding and the like, can be judged.
Specifically, the ear position data and the finger position data are corresponding position data, pressure data can be acquired through a plurality of pressure sensors, the ear position data and the finger position data can be determined through the pressure data, and for example, whether the position of the left ear or the position of the right ear closest to the terminal is judged through the shape of a pressure profile sensed by the pressure sensors.
S10212, determining the mouth position of the user according to the ear position data and the finger position data.
After the position data of the human ears is used for obtaining whether the holding hand currently holding the terminal is the left hand or the right hand, the front of the current terminal (the direction same as the human face) is judged by combining the position data of the fingers, and according to the habits of most users, the front of the terminal in the direction same as the human face is generally considered to be the position of the mouth of the user.
Of course, the method for determining the mouth position of the user is not limited to the method using the data including the position data of the human ear and the position data of the finger sensed in the interior, and other methods may be used, for example, gravity sensing may be used, and the method may be flexibly selected according to the actual situation, considering that the lower end (the side closer to the ground) of the terminal is the mouth position of the user.
S10213, at least the sound receiving unit with the smallest distance with the position of the mouth of the user is determined as a candidate sound receiving unit.
On the basis of the determined position of the user's mouth, the terminal can obtain the position of the terminal corresponding to the user's mouth, and at least the sound receiving unit closest to the position can be used as the candidate sound receiving unit. That is, the candidate sound receiving unit does not necessarily have to be one, but must include a sound receiving unit that is the smallest distance from the position of the user's mouth.
Generally, the closer the sound source is to the sound receiving unit, the higher the quality of the sound collected by the sound receiving unit. Selecting the sound receiving unit having the smallest distance from the user's mouth position as the candidate sound receiving unit can ensure the quality of the sound collected by the sound receiving unit.
In some embodiments, referring to fig. 5, determining the master sound receiving unit based on the locations of the candidate sound receiving units and the location of the working sound emitting unit (S1022) includes:
s10221, dividing the terminal into a plurality of areas according to the positions of all the sound units, each area having at least one sound unit.
The terminal is divided into a plurality of areas according to the positions of all the sound generating units, and when the areas are divided, the number of the sound generating units in each area is not required to be consistent, the size of each area is also not required to be consistent, but at least one sound generating unit in each area is ensured.
S10222, if the working sound generating unit does not exist in the area where the candidate sound receiving unit is located, determining that the candidate sound receiving unit is the main sound receiving unit.
After the area division is finished, the terminal judges the state of the sound generating unit of the area where the candidate sound receiving unit is located, and if the area where the candidate sound receiving unit is located does not have a working sound generating unit, the candidate sound receiving unit is selected as a main sound receiving unit, namely a sound receiving unit for collecting the sound of the user.
When the area where the candidate sound receiving unit is located does not have the working sound generating unit, it can be considered that the sound generated by the working sound generating unit has a small influence on the candidate sound receiving unit when the candidate sound receiving unit works, that is, under this condition, the echo collected by the candidate sound receiving unit is small, so that the candidate sound receiving unit can be selected as the main sound receiving unit, and other sound receiving units can be closed or used for performing optimization processing on the main audio signal, such as noise reduction, echo cancellation and the like, so as to achieve better noise reduction effect and echo suppression effect, and finally help the user obtain better sound quality experience.
S10223, if the working sound generating unit exists in the area where the candidate sound receiving unit is located, the non-candidate sound receiving unit is selected as the main sound receiving unit.
If the working sound generating unit exists in the area where the candidate sound receiving unit is located, the non-candidate sound receiving unit is selected as a main sound receiving unit, namely a sound receiving unit for receiving a main audio signal (such as the sound of a user speaking).
When the working sound generating unit exists in the area where the candidate sound receiving unit is located, it can be considered that the sound generated by the working sound generating unit has a large influence on the candidate sound receiving unit when the candidate sound receiving unit works, that is, in this case, the echo or noise collected by the candidate sound receiving unit is large, and because the influence of the echo or noise on the call quality is large, the candidate sound receiving unit should not be selected as the main sound receiving unit, and the non-candidate sound receiving unit should be selected as the main sound receiving unit.
Of course, the method of determining the master sound receiving unit based on the candidate sound receiving unit positions and all the sound emitting unit positions is not limited to this, and may be selected by the distance between the candidate sound receiving unit and the sound emitting unit. According to the practical situation, a proper method can be selected to reduce the influence of echo on the call quality.
