The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be noted that all directional indicators (such as up, down, left, right, front, and rear … …) in the embodiments of the present invention are merely used to explain the relative positional relationship, movement, etc. between the components in a particular posture (as shown in the drawings), and if the particular posture is changed, the directional indicator is changed accordingly.
Furthermore, the description of "first," "second," etc. in this disclosure is for descriptive purposes only and is not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions of the embodiments may be combined with each other, but it is necessary to base that the technical solutions can be realized by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not within the scope of protection claimed in the present invention.
At present, a plurality of earphones have the noise reduction function so as to reduce the influence of surrounding environment noise on users and improve the definition and comfort level of listening to the earphone by the users. However, in practical applications, the noise reduction earphone also reduces the sound of surrounding people, so that the user wearing the noise reduction earphone or wearing the earphone in the noise reduction working state can easily not hear the sound of the conversation between other people and the user, and the experience of the user is reduced.
Therefore, the invention provides a headset control method. It will be appreciated that the earphone is provided with a control device for storing and executing the method described below, and the control device may be implemented by a main controller, for example, an MCU (Microcontroller Unit, micro control unit), DSP (Digital Signal Process, digital signal processing Chip), FPGA (Field Programmable Gate Array, programmable gate array Chip), SOC (System On Chip), etc. Wherein the headphones comprise a left headphone and a right headphone, one of which may be provided with the above-described control device, and control of the other is achieved by a self-contained communication module to perform the method described below.
Referring to fig. 1, in an embodiment of the present invention, a headset control method includes:
step S100, the earphone acquires a human voice signal in the environment and generates a corresponding reference audio signal according to the human voice signal;
in this embodiment, the headphones include left and right headphones, and the microphone or microphone may be disposed on the outer sides of the left and right headphones to obtain environmental sound, and according to the obtained environmental sound, determine the voice signals sent by different people, for example, voice recognition modules are disposed in the headphones to identify the voice signals, and generate the voice signals sent by at least one person according to the frequency and amplitude of the sound.
Optionally, in an embodiment, referring to fig. 2, step S100 specifically includes:
step S110, the earphone acquires a human voice signal in the environment and performs voice recognition on the human voice signal;
step S120, when the preset keyword is identified, the voice signal is set as a reference audio signal.
In this embodiment, the preset keywords may be set by the user, and may be the name, foreign number, title, job title, etc. of the user, for example, the name of the user is called X-hao, and is the supervisor, and then the preset keywords may include X-hao, X-teacher, etc. When the control device judges that a certain voice signal comprises a preset keyword through voice recognition, the voice signal can be confirmed to be a voice signal output by a person needing to speak to the user, namely the reference audio signal represents the content which is said to the user by the person with the requirement of speaking to the user.
It should be understood that in practical applications, there are also situations where keywords are preset in the content of the utterances of different people, for example, currently, person a needs to find person B to arrange a thing, person B has proposed the name of the user, and person a then turns to recite some content to the user after having proposed the name of the user. At this time, the voice signal of the person a and the voice signal of the person B include preset keywords.
For this purpose, referring to fig. 3, in another embodiment of the present invention, the number of the voice signals is plural, and step S120 specifically includes:
step S121, when a preset keyword is identified in a voice signal and a preset keyword is not identified in another voice signal within a preset time period, setting the voice signal comprising the preset keyword as a reference audio signal;
in this embodiment, the preset duration may be preset in advance by a developer and pre-stored in the control device. If the control device is within the preset time period and recognizes other voice signals which also include the preset keywords, the voice signals including the preset keywords can be directly set as the reference audio signals.
Step S122, when the preset keywords are identified in the plurality of voice signals, sorting the plurality of voice signals comprising the preset keywords according to the sequence of the voice signals identified, so as to generate and determine a first sequence;
step S123, setting the last-ranked human voice signal in the first sequence as the reference audio signal.
In this embodiment, if a plurality of voice signals include preset keywords, the voice signals may be identified to be ranked according to the sequence of the voice signals, specifically, in actual situations, a person who may refer to the voice signals for multiple times or a person speaking to the user may refer to the voice signals for multiple times after the person refers to the preset keywords, and after the person finds that the user does not respond to the voice signals, the step of ranking the voice signals including the preset keywords according to the sequence of the voice signals includes: and sequencing the plurality of voice signals comprising the preset keywords according to the sequence of the voice signals which are identified last time, and then generating and determining a first sequence. The control means will then take the last ranked human voice signal in the first sequence as the reference audio signal. It will be appreciated that in actual situations, only the person who finally utters the preset keyword will often actually have a need to speak to the user. Therefore, by the arrangement, it is possible to confirm which user who emits the voice signal actually has a speaking demand for the user among the plurality of voice signals including the preset keyword, thereby setting the accuracy of the reference audio signal.
Step 200, acquiring the direction of a sound source emitting a reference audio signal relative to a user;
optionally, in an embodiment, referring to fig. 4, step S200 specifically includes:
step S210, acquiring the phase of a reference audio signal received by a left earphone of the earphone and taking the phase as a first phase; the phase of the reference audio signal received by the right earphone of the earphone is obtained and used as a second phase;
step S220, determining the direction of the sound source emitting the reference audio signal relative to the user according to the phase difference between the first phase and the second phase.
In this embodiment, the control device may determine, according to the phase difference between the reference audio signals received by the left earphone and the right earphone, the direction of the audio source emitting the reference audio signal relative to the user, that is, determine the position of the person who needs to speak to the user relative to the user. Such as left, right, front, back, etc. of the user.
Step S300, according to the direction, controlling the corresponding left earphone and/or right earphone in the earphone to exit the noise reduction mode and/or reducing the amplitude of the audio output to the ears of the user.
Optionally, in an embodiment, step S300 specifically includes:
step S310, when the direction is the left side of the user, controlling the left earphone to exit the noise reduction mode and/or reducing the amplitude of the audio output to the left ear of the user by the left earphone by a first preset amplitude;
step S320, when the direction is the right side of the user, controlling the right earphone to exit the noise reduction mode and/or reducing the amplitude of the audio output by the right earphone to the right ear of the user by a first preset amplitude;
step S330, when the direction is the front of the user or the back of the user, controlling the left earphone and the right earphone to exit the noise reduction mode and/or reducing the amplitude of the audio output by the left earphone to the left ear of the user by a second preset amplitude, and reducing the amplitude of the audio output by the right earphone to the right ear of the user by the second preset amplitude; the second preset amplitude value is smaller than the first preset amplitude value.
It will be appreciated that during the performance of the above-described method of the present application, the user is typically wearing headphones, and that the headphones are in a noise reduction mode during the output of audio to the user's ears and/or headphones. In this embodiment, if the person currently speaking to the user is located on the left side of the user. The left side comprises a left front side and a left rear side, and then the control device can control the left earphone to exit the noise reduction mode and/or reduce the amplitude of the audio output by the left earphone to the left ear of the user by a first preset amplitude value, so that the user can hear the content of speaking of the person on the left side of the user without picking up the left earphone, and simultaneously, the information transmitted by the right earphone and/or the left earphone can be received, and the influence of environmental noise on the user is reduced to a certain extent, for example, the earphone is connected with a mobile phone in a wireless communication way, and the telephone voice content of other people is simultaneously received through the mobile phone. Similarly, if the person currently speaking to the user is located on the right side of the user. The right side comprises a right front side and a right rear side, and then the control device can control the right earphone to exit the noise reduction mode and/or reduce the amplitude of the audio output by the right earphone to the right ear of the user by a first preset amplitude value so as to achieve the same effect. In addition, when the direction is the right front of the user or the right rear of the user, then the control device simultaneously adjusts the left earphone and the right earphone, namely, controls the left earphone and the right earphone to exit the noise reduction mode and/or reduces the amplitude of the audio output by the left earphone to the left ear of the user by a second preset amplitude and reduces the amplitude of the audio output by the right earphone to the right ear of the user by a second preset amplitude. When the person speaking to the user is positioned right in front of the user relative to the user, the left ear and the right ear of the user can both receive the speaking content, so that the left earphone and the right earphone can be controlled to work simultaneously, and the amplitude of the audio output to the ears of the user is reduced by a second preset amplitude smaller than the first preset amplitude, so that the same effect is achieved. Therefore, when the user uses the earphone and the earphone is in the noise reduction mode and/or outputs audio to the user, the earphone not only can identify that a person in the current environment speaks to the user, but also can adjust the working state of the corresponding left earphone and/or right earphone according to the direction of the sound source which speaks to the user, so that the user can hear the content of the user which speaks to other people, and meanwhile, the user can not miss the information transmitted to the user in the ear through the earphone, and the user does not need to take down the earphone, thereby effectively improving the convenience of using the earphone by the user.
The invention discloses an earphone control method, which comprises the steps of firstly obtaining a human voice signal in the environment, generating a corresponding reference audio signal according to the human voice signal, then obtaining the direction of a sound source sending the reference audio signal relative to a user, and finally controlling a corresponding left earphone and/or right earphone in the earphone to exit a noise reduction mode and/or reduce the amplitude of audio output to ears of the user according to the direction. Therefore, when the user uses the earphone and the earphone is in the noise reduction mode and/or outputs audio to the user, the earphone not only can identify that a person in the current environment speaks to the user, but also can adjust the working state of the corresponding left earphone and/or right earphone according to the direction of the sound source which speaks to the user, so that the user can hear the content of the user which speaks to other people, and meanwhile, the user can not miss the information transmitted to the user in the ear through the earphone, and the user does not need to take down the earphone, thereby effectively improving the convenience of using the earphone by the user.
It should be appreciated that in a practical situation, after the user hears the reference audio signal via the left and/or right headphones (after exiting the noise reduction mode and/or reducing the amplitude of the audio output to the user's ear) adjusted by the above-mentioned operating state, the user may turn to the object to which he is currently speaking, or to another target object, for example: currently, person A speaks into the user and informs person B of something, and the user turns to face B to listen while turning.
To this end, in an embodiment of the invention, referring to fig. 5, the method further comprises:
step S400, setting the direction in step S200 as a first direction;
after step S300, the method further comprises:
step S500, the direction of a sound source emitting a reference audio signal relative to a user is obtained and is used as a second direction;
in this embodiment, after the working state of the left earphone and/or the right earphone is adjusted, that is, after the user can hear the voice of the person speaking into the left earphone and/or the right earphone, the control device further obtains the direction of the sound source emitting the reference audio signal relative to the user through the above process, and uses the direction as the second direction.
Step S600, when the second direction is consistent with the first direction, controlling the left earphone and the right earphone to keep the current working state;
in this embodiment, the user does not change his head posture, for example, change his head orientation, because he needs to listen to his voice, and the control device may adjust the operation states of the left and/or right earphones in the same manner as in step S300, even if he maintains the current operation state.
Step S700, when the second direction is inconsistent with the first direction and the second direction is the right front of the user or the right rear of the user, controlling the left earphone and the right earphone to exit the noise reduction mode and/or reducing the amplitude of the audio output by the left earphone to the left ear of the user by a second preset amplitude, and reducing the amplitude of the audio output by the right earphone to the right ear of the user by the second preset amplitude;
in this embodiment, the user, after hearing the other person and he speaks, will turn his head towards the person speaking to him. Then, the direction of the sound source emitting the reference audio signal relative to the user is the front of the user, i.e. the second direction is the front of the user. At this time, the control device controls the left earphone and the right earphone to exit the noise reduction mode and/or reduces the amplitude of the audio output by the left earphone to the left ear of the user by a second preset amplitude, and reduces the amplitude of the audio output by the right earphone to the right ear of the user by a second preset amplitude. Therefore, the user can listen to the content of the speaker and simultaneously listen to the information transmitted from the earphone, and the convenience of using the earphone by the user is effectively improved.
Step S800, when the second direction is inconsistent with the first direction and the second direction is the left side of the user or the right side of the user, controlling the left earphone or the right earphone corresponding to the second direction to exit the noise reduction mode and/or reducing the amplitude of the audio output to the ear of the user.
In this embodiment, the user may turn to another target to conduct a conversation after hearing the other person and he speaks. For example, when the person a currently located on the left front side of the user speaks into the user and wants to let the user instruct the person B on the left side of the user to perform some operations, the user turns to the person B by himself after hearing the sound of the person a, and instructs the user according to what the person a speaks, and at this time, the direction of the person a relative to the user becomes the right front side. Therefore, if the second direction is inconsistent with the first direction and the second direction is the left side of the user or the right side of the user, the control device can control the left earphone or the right earphone corresponding to the second direction to exit the noise reduction mode and/or reduce the amplitude of the audio output to the ears of the user, so that after the position of the person speaking to the user changes relative to the user, the user can still be ensured to hear the content of the person speaking to the user under the condition of wearing the earphone, and the convenience of the user for using the earphone is effectively improved.
It should be understood that after the user and other people finish the conversation, the working state of the earphone needs to be adjusted to the previous working state by self-help, which is quite inconvenient.
To this end, based on the above embodiment, referring to fig. 6, in an embodiment of the present invention, the method further includes:
step 900, acquiring the head gesture of the user, and setting the current head gesture as a first gesture when executing step 200; a second posture that sets the current head posture when step S700 or step S800 is performed;
step S1000, when the user 'S direction is switched back from the second posture to the first posture, controlling the left earphone and/or the right earphone to resume the noise reduction mode and resume the amplitude of the audio output to the user' S ear.
In this embodiment, the left earphone and the right earphone may be provided with gesture detection modules, such as an acceleration sensor, a gyroscope, and the like, and the control device provided in the left earphone or the right earphone may determine the head gesture of the user, for example, confirm the head orientation of the user, based on the gesture detection data output by the gesture detection modules in the two. For example, referring to fig. 7, fig. 7 is a top view of the head of the user, wherein the top view of the head is implemented as a posture a when the head of the user faces straight ahead, and the top view of the head of the broken line is implemented as a posture B when the head of the user faces leftward.
Specifically, when the control device executes step S200, that is, determines the direction of the audio source of the current reference audio signal relative to the user, the control device sets the current head gesture of the user to a first gesture, where the first gesture represents the head gesture of the user immediately before the left earphone and/or the right earphone after the adjustment of the working state hear the reference audio signal. Similarly, when the control device executes step S700 or step S800, it is described that the user has heard the user speaking into the user, and then the head turns to the direction of the audio source of the reference audio signal or the direction of the target of the conversation required by the user, and the head posture of the user is the second posture. For example, referring to fig. 7, the posture a in fig. 7 is a first posture, at which time the user is using the computer in front of himself normally and the head is directed toward the front, at which time someone speaks into the user and the talking person is located in front of the user on the left, and the head posture of the user is adjusted to the posture B to be directed toward the talking person, i.e., a second posture. It will be appreciated that when the user has finished talking to another person, i.e. no longer has a need to talk to a person, the head pose is adjusted from pose B back to pose a, for example as shown in fig. 7, when the user has finished talking. I.e. the head pose of the user is adjusted from the second pose back to the first pose. Then the control means may assume that the current user has no need to listen to the other person, and may control the left and/or right earphone to resume the noise reduction mode and resume the amplitude of the audio output to the ear of the user, i.e. to resume the initial state of the earphone (refer to the state of the earphone before performing step S300). Through the setting, the earphone can self-help recognize that the user finishes the conversation requirement with other people, or does not need to listen to the speaking content of other people, and automatically adjusts back to the initial state, so that the earphone does not need manual adjustment by the user, and the convenience of using the earphone by the user is effectively improved.
It will be appreciated that in another embodiment, if the user listens to the speaking content of other people in a posture consistent with the first posture, or if the user does not adjust his head posture (i.e. when executing step S600). The control device controls the earphone to restore to the initial state when the reference audio signal is not detected within the preset second time period.
The invention also proposes a control device comprising:
