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 invention.
As shown in fig. 1, an embodiment of the present invention provides an audio output method applied to an electronic device, where the method includes:

Step 12: and when the distance between the electronic equipment and the target object is updated to a first preset range, the electronic equipment outputs audio data in a directional sound transmission mode.
Optionally, the electronic device has a sound transmission component, and the sound transmission component has a directional sound transmission mode (namely, audio data can be output in a directional sound transmission mode) and a non-directional sound transmission mode (namely, audio data can be output in a non-directional sound transmission mode). For example: the sound transmission assembly may comprise a directional sound transmission device and a non-directional sound transmission device, wherein the directional sound transmission device implements a directional sound transmission mode and the non-directional sound transmission device implements a non-directional sound transmission mode. For another example: the acoustic transmission assembly may include an acoustic transmission device having a non-directional acoustic transmission mode and a directional acoustic transmission mode.
Optionally, the sound transmission component may be an earpiece, a speaker, or the like in the electronic device, and the sound transmission component may modulate the audio signal into the ultrasonic signal, and self-demodulate an audible sound beam with high directivity by using a nonlinear interaction when the ultrasonic wave is transmitted in the air, that is, a directional sound transmission mode; the directional sound transmission mode is to limit the sound waves to be directionally transmitted in a certain direction, and the sound field is distributed in a long and narrow conical shape, so that the sound waves can be hardly acquired or only weak sound waves can be acquired in the area outside the sound field, and the privacy of sound transmission is ensured. The sound transmission component can also be provided with a non-directional sound transmission mode, the non-directional sound transmission mode directly generates sound through the vibration of air molecules of the loudspeaker according to the linear acoustic theory, so that sound waves are transmitted to all directions, and the sound field is approximately distributed in a spherical shape.
Optionally, the electronic device includes but is not limited to: the mobile phone, the tablet personal computer, the wearable device (such as a smart watch, a smart bracelet, an earphone and the like), the computer, the smart television and the like. For example: taking a mobile phone as an example, the sound transmission assembly may be disposed at any one or combination of the top, the bottom and the side of the mobile phone, and the embodiment of the present invention is not particularly limited.
Optionally, the electronic device defaults that the electronic device outputs the audio data in a non-directional sound transmission manner in a case where the electronic device outputs the audio data through a receiver, such as a voice call, a voice output in a video call, an audio output in an instant messaging application, and the like; when the distance between the electronic equipment and the target object is detected to be within a first preset range, if the electronic equipment is close to the ear of a person, the electronic equipment is switched to output audio data according to a directional sound transmission mode, so that privacy protection is achieved when the audio data are output through the earphone, and privacy safety of audio output is improved.
Optionally, after the step 11, the method may further include: when the distance between the electronic device and the target object is updated to a first predetermined range, if an earphone (such as a wired earphone or a wireless earphone) is connected to the electronic device, the electronic device outputs audio data through the earphone.
In the above scheme, when the distance between the electronic device and the target object is updated to the first predetermined range, the electronic device switches from outputting the audio data in the non-directional sound transmission mode to outputting the audio data in the directional sound transmission mode, so that when a user needs to listen to the audio data with high privacy close to the electronic device, the risk of privacy disclosure can be reduced by switching the directional sound transmission mode to output the audio data, and the privacy security of audio output is improved.
As shown in fig. 2, an embodiment of the present invention further provides an audio output method, including:
step 21: the electronic equipment outputs audio data in a non-directional sound transmission mode.
Step 22: and when the distance between the electronic equipment and the target object is updated to a first preset range, the electronic equipment outputs audio data in a directional sound transmission mode.
Step 23: and when the distance between the electronic equipment and the target object is updated to exceed the first preset range and the distance between the electronic equipment and the target object is updated to the first preset range again, the electronic equipment outputs audio data in a non-directional sound transmission mode.
Optionally, taking a voice call as an example, when the user answers the electronic device by approaching the electronic device to an ear, the electronic device outputs audio data in a directional sound transmission manner, so as to improve privacy security of audio data output; furthermore, the user can switch the electronic device to output the audio data in a non-directional sound transmission mode by keeping the electronic device away from the ear and getting close to the ear again, so that the output mode of the audio data can be switched quickly, and the complicated operation that the user needs to switch the output mode of the audio data through the input aiming at the display interface is avoided.
Optionally, the step 23 may further include:
when the distance between the electronic equipment and the target object is updated to exceed the first preset range and the time length exceeding the first preset range exceeds a first preset time period, the electronic equipment keeps outputting audio data in a directional sound transmission mode;
and after the distance between the electronic equipment and the target object is updated to exceed the first preset range, and under the condition that the distance between the electronic equipment and the target object is updated to the first preset range again in the first preset time period, the electronic equipment outputs audio data in a non-directional sound transmission mode.
For example: in a call mode, under the condition that the electronic equipment is close to an ear or is in an ear answering state, if the state that the electronic equipment is far away from the ear or not close to the ear is detected and a first preset time period is reached, the electronic equipment can keep outputting audio data in a directional sound transmission mode; if the electronic equipment is detected to be close to the ear or is already in the state of listening to the ear again within a first preset time period after the electronic equipment is detected to be away from the ear or not close to the ear, the electronic equipment is automatically switched to the previous mode, namely: outputting audio data in a non-directional sound transmission mode; or the audio data can be output through the earphone under the condition that the electronic equipment is connected with the earphone, so that the rapid switching of the output mode of the audio data is realized, and the timeliness of the response of the electronic equipment and the accuracy of the switching of the output mode of the audio data are favorably ensured by setting the time limit of the switching response.
Optionally, according to at least one of the above embodiments, the method may further include:
the method comprises the steps that when the distance between the electronic equipment and a target object is updated to a first preset range, the electronic equipment displays a first icon;
the first icon is used for instructing the electronic equipment to output audio data in a directional sound transmission mode.
For example: under the condition that the electronic equipment is in a call mode, if the current display interface is a telephone answering interface, the first icon can be displayed on the telephone answering interface; if the current telephone interface is in background operation, the first icon can be displayed in the top status bar; and if the current display interface is a screen locking interface, displaying the first icon on the screen locking interface. In this way, the first icon is displayed in the display screen, so that the user is prompted that the current electronic equipment outputs audio data in a directional sound transmission mode.
Optionally, after the step of displaying the first icon by the electronic device, the method may further include:
receiving a first input of the first icon by a user;
responding to the first input, the electronic equipment outputs audio data in a non-directional sound transmission mode, and updates the first icon to be a second icon;
the second icon is used for instructing the electronic equipment to output audio data in a non-directional sound transmission mode.
For example: the first input may be a click input for the first icon, or a slide input acting on the first icon and along a certain distance, or a slide input acting on the first icon and along a predetermined trajectory, and the like, which is not limited in this embodiment of the present invention.
Further, under the condition that the second icon is displayed in a display interface in the electronic equipment, second input of the user to the second icon can be received; and responding to the second input, the electronic equipment is switched to output audio data in a directional sound transmission mode, and the second icon is updated to be the first icon.
In this embodiment, a user switches an output mode of audio data of the electronic device by inputting the first icon displayed in the display interface of the electronic device, so that the user can perform manual switching when knowing the audio output mode of the current electronic device, and misoperation caused by blind switching is avoided.
Optionally, according to at least one of the above embodiments, in a case that the distance between the electronic device and the target object is updated to the first predetermined range, the step of outputting, by the electronic device, the audio data in a directional sound transmission manner may further specifically include:
and when the distance between the electronic equipment and the target object is updated to a first preset range, the electronic equipment outputs audio data in a directional sound transmission mode through the first sound transmission component.
Further, after the step of outputting, by the electronic device, audio data in a directionally-sound manner through the first sound-transmitting component in a case where the distance between the electronic device and the target object is updated to the first predetermined range, the method may further include:
and when the distance between the electronic equipment and the target object is updated to a second preset range, the electronic equipment is switched to output the audio data in a directional sound transmission mode through the second sound transmission component.
Alternatively, the first acoustic assembly may be an earpiece and the second acoustic assembly may be a speaker; for example: when the electronic equipment is in a call mode and audio data are output through an earphone in a directional sound transmission mode, if the fact that the distance from the electronic equipment to a user (such as the ear of the user) is updated to a second preset range is detected, the electronic equipment is directly switched to output the audio data through a loudspeaker; the second predetermined range may be a distance range in which the audio data output by the earphone does not satisfy the user listening condition, so that the user listening effect of the audio data is ensured by switching to the speaker to output the audio data.
Further, when the electronic device is switched to output the audio data through the loudspeaker, the loudspeaker outputs the audio data in a directional sound transmission mode to reduce the risk of privacy disclosure, and therefore the privacy safety of audio output is improved.
Optionally, an embodiment of the present invention further provides an audio output method, which is applied to an electronic device, and the method includes:
determining a current audio output mode of the electronic device.
Optionally, the audio output modes may include, but are not limited to: a call mode (such as a voice call mode and a video call mode), a voice chat mode (such as voice chat can be realized through a communication application with a voice conversation function), an audio play mode, a video play mode, and the like.
And under the condition that the current audio output mode is the target output mode, the electronic equipment outputs audio data in a directional sound transmission mode.
Optionally, the target output mode may be a preset audio output mode that requires outputting audio data in a directional sound transmission manner, for example: the user can preset any one or combination of a call mode, a voice chat mode, an audio playing mode, a video playing mode and the like as a target output mode according to the use requirement.
Of course, the target output mode may also be pre-configured by the system, for example: aiming at audio output modes with higher privacy requirements such as a call mode, a voice chat mode and the like, a target output mode can be preset by the system; therefore, when the electronic equipment is in the target output mode, the sound transmission component is controlled to be switched to the directional sound transmission mode, so that the audio signal in the target output mode can be directionally transmitted in the preset direction, and the risk of privacy disclosure can be reduced to a certain extent.
For another example: the system can also be configured with a target output mode in advance as an audio play mode, a video play mode and the like, so that when the electronic equipment is in the target output mode, the electronic equipment is switched to a directional sound transmission mode to output audio data, so that an audio signal in the target output mode can be directionally transmitted in a preset direction, and the interference to the external environment during audio/video play can be reduced to a certain extent.
Optionally, after the step of determining the current audio output mode of the electronic device, the method may further include: and under the condition that the current audio output mode is not the target output mode, acquiring audio data to be output.
Determining a target sound transmission mode of the electronic equipment for outputting the audio data according to the source application of the audio data and/or the content of the audio data; the target sound transmission mode is one of the directional sound transmission mode and the non-directional sound transmission mode.
Specifically, under the condition that the current audio output mode is not the target output mode, if the source application of the audio data and/or the content of the audio data meets a preset condition, the electronic device outputs the audio data in the directional sound transmission mode; and if the source application of the audio data and/or the content of the audio data do not meet the preset conditions, the electronic equipment outputs the audio data in a non-directional sound transmission mode.
For example: under the condition that the target output mode is a call mode or a voice chat mode, if it is detected that the audio data to be output is from applications such as a recording application and the like which may have privacy disclosure risks, and/or when the audio data to be output contains preset keywords (such as keywords carrying privacy information), outputting the audio data in a directional sound transmission mode when the audio data is played, so that the audio data can be directionally transmitted in a preset direction, and the risk of privacy disclosure can be reduced to a certain extent.
Optionally, the step of determining a target microphone transmission mode of the electronic device for outputting the audio data according to the source application of the audio data may specifically include:
acquiring a source application of the audio data;
under the condition that the source application is a target application, the electronic equipment outputs the audio data in a directional sound transmission mode;
in the case that the source application is not the target application, the electronic device outputs the audio data in the non-directional transaudient manner.
Wherein, the target application can be preset by a user or preset by a system; if the target application may be a recording application, an application that sends verification code information in a voice manner, and the like, which is not limited in the embodiments of the present invention.
Optionally, the step of determining, according to the content of the audio data, a target microphone manner in which the electronic device outputs the audio data may specifically include:
performing content identification processing on the audio data, and determining whether the content of the audio data contains preset keywords;
under the condition that the content of the audio data contains the preset keywords, the electronic equipment outputs the audio data in a directional sound transmission mode;
and under the condition that the content of the audio data does not contain the preset keywords, the electronic equipment outputs the audio data in a non-directional sound transmission mode.
The preset keywords can be set by a user in a self-defined mode, or are configured by the system in advance, or can be determined by the system in a big data processing mode; such as: the preset keyword may be verification code information, user identity information, property data information, and the like, which is not limited in the embodiments of the present invention.
Optionally, the step of determining a target microphone transmission mode of the electronic device for outputting the audio data according to the source application of the audio data and the content of the audio data may specifically include:
acquiring a source application of the audio data;
under the condition that the source application is a target application, the electronic equipment outputs the audio data in a directional sound transmission mode;
under the condition that the source application is not the target application, performing content identification processing on the audio data, and determining whether the content of the audio data contains a preset keyword or not;
under the condition that the content of the audio data contains the preset keywords, the electronic equipment outputs the audio data in a directional sound transmission mode;
and under the condition that the content of the audio data does not contain the preset keywords, the electronic equipment outputs the audio data in a non-directional sound transmission mode.
In this embodiment, only when the current audio output mode of the electronic device is not the target output mode and the source application of the audio data to be output is not the target application, whether the content of the audio data includes the preset keyword is determined through the content identification processing, so that the data processing amount of performing the content identification processing on each audio data can be reduced, and the processing efficiency can be improved to a certain extent.
Optionally, according to at least one of the above embodiments, when the current audio output mode is the target output mode, the step of outputting, by the electronic device, the audio data in the directional sound transmission manner may specifically include:
under the condition that the current audio output mode is a target output mode, if the fact that the distance between the electronic equipment and a target object is updated to a first preset range is detected, the electronic equipment outputs the audio data in a directional sound transmission mode;
further, after the electronic device outputs the audio data in the directional sound transmission manner, the method further includes:
and when the fact that the distance between the electronic equipment and the target object is updated to exceed the first preset range and the distance between the electronic equipment and the target object is updated to the first preset range again is detected, the electronic equipment switches from outputting the audio data in the directional sound transmission mode to outputting the audio data in the non-directional sound transmission mode.
Specifically, when the electronic device is in a call mode (such as just making a call or making a call), the electronic device defaults to outputting audio data in a non-directional sound transmission manner; if the electronic equipment is detected to be close to the ear or is already in the ear answering state, the electronic equipment is automatically switched to output the audio data in a directional sound transmission mode, and the rapid switching of the output mode of the audio data is realized.
Further, when the electronic device is in a call mode and the electronic device is close to an ear or already in an ear answering state, if it is detected that the electronic device is away from the ear or not and reaches a first preset time period, the electronic device can keep outputting the audio data in a current directional sound transmission manner; if the electronic equipment is detected to be away from the ear or not within the preset time period of the ear state, the electronic equipment is detected to be close to the ear again or is detected to be in the ear answering state, the electronic equipment is automatically switched to output the audio data in a non-directional sound transmission mode, so that the rapid switching of the output mode of the audio data of the electronic equipment in the conversation mode is realized, and the timeliness of the electronic equipment response and the accuracy of the output mode switching of the audio data are favorably ensured by setting the time limit of switching response.
Optionally, according to at least one of the above embodiments, when the current audio output mode is the target output mode, the step of the electronic device outputting the audio data in the directional sound transmission manner may specifically include:
and under the condition that the electronic equipment is in a target audio output mode and the electronic equipment is not connected with an earphone, the electronic equipment outputs the audio data in a directional sound transmission mode.
Specifically, as an implementation: when the electronic equipment is in a call mode (such as calling or putting through a call), detecting whether the electronic equipment is connected with an earphone (such as a Bluetooth earphone, a wired earphone and the like) currently; if the electronic equipment is detected to be connected with the earphone currently, outputting audio data through the earphone; and if the electronic equipment is detected not to be connected with the earphone currently, the electronic equipment outputs the audio data in the directional sound transmission mode.
Further, when the electronic device is in a call mode and the electronic device is close to an ear or is already in an ear answering state, if it is detected that the electronic device is away from the ear or not and reaches a first preset time period, the electronic device can keep outputting the audio data in a current directional sound transmission manner; if the electronic equipment is detected to be close to the ear or is already in the ear listening state within the preset time period when the electronic equipment is detected to be away from the ear or not, the electronic equipment is automatically switched to the previous mode (for example, the electronic equipment outputs the audio data in a non-directional sound transmission mode or outputs the audio data through an earphone), so that the rapid switching of the output mode of the audio data in the call mode is realized.
Specifically, as another implementation: when the electronic equipment is in a call mode (such as calling or putting through a call), detecting whether the electronic equipment is connected with an earphone (such as a Bluetooth earphone, a wired earphone and the like) currently; if the electronic equipment is detected to be connected with the earphone currently, outputting audio data through the earphone; if the electronic equipment is detected not to be connected with the earphone currently, the electronic equipment outputs audio data in a non-directional sound transmission mode in a default mode; and if the electronic equipment is detected to be close to the ear or is in an ear answering state, the electronic equipment automatically switches to output the audio data in a directional sound transmission mode.
Optionally, when the electronic device is in a call mode and after it is detected that the electronic device is currently connected with an earphone, if it is detected that the electronic device is switched from a state of being connected with the earphone to a state of not being connected with the earphone and the distance between the electronic device and the target object is greater than a second predetermined distance, the speaker is started to output the audio data in a directional sound transmission manner, so as to ensure that the user answers the audio data by switching to the speaker to output the audio data when the distance between the electronic device and the user does not meet the condition that the user answers through the earphone, and the speaker outputs the audio data in the directional sound transmission manner, which is further beneficial to reducing the risk of privacy disclosure, thereby improving the privacy security of audio output.
In the scheme, the electronic equipment can automatically switch different sound transmission modes to output audio data by identifying different audio output modes, and manual operation of a user can be reduced. In addition, the electronic equipment outputs the audio data in a directional sound transmission mode in a specific scene so as to reduce the privacy leakage risk during audio data output and improve the privacy security of audio data output.
