Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is apparent that the embodiments described below are only some embodiments of the present invention, not all embodiments of the present 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.
In the description of the present invention, it will be understood that when one component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present.
Furthermore, the terms "long," "short," "inner," "outer," and the like, as used herein, refer to an orientation or positional relationship based on that shown in the drawings, for convenience of description of the present invention, and are not intended to indicate or imply that the apparatus or elements referred to must have this particular orientation, operate in a particular orientation configuration, and thus should not be construed as limiting the invention.
Because the structure of the open earphone is natural, when in use, the ear can receive external sound, so that the earphone has a more natural listening feeling, and the open structure can make the sound of the earphone possibly form a leakage sound, in the prior art, the mode of emitting inverted audio like the external environment is mainly adopted to overcome the leakage sound, but in some scenes, a user may need to isolate the environmental sound, so that the sound of the earphone can be clearer.
The present invention aims to provide a solution to meet the aforementioned needs.
The technical scheme of the invention is further described below by the specific embodiments with reference to the accompanying drawings.
Example 1
Referring to fig. 1 and fig. 2 in combination, the embodiment of the invention provides a method for switching a sound receiving mode of an earphone; wherein the earphone comprises a first horn 31 configured to emit a first audio signal to the ear canal and a second horn 32 configured to emit a second audio signal outside the ear. The outer ear has an open channel that allows a third audio signal (i.e., ambient sound) to pass into the ear canal; in the normal sound reception mode, the first audio signal and the second audio signal are generated synchronously so as to counteract the leakage of the first audio signal outside the ear.
Wherein the second audio signal is determined based on the first audio signal, specifically an audio signal obtained by performing time domain inversion according to the first audio signal; when the second audio signal is emitted to the external environment, the distance difference between the first loudspeaker 31 and the second loudspeaker 32 is smaller than the distance difference between the far fields, so that the part of the first audio signal leaked to the external environment can be well counteracted, and the purpose of avoiding sound leakage is achieved.
Referring to fig. 3, in this embodiment, the switching method includes:
s11, acquiring a first switching parameter in a common radio mode;
S12, when the first switching parameter meets the closed radio condition, switching the radio mode of the earphone into the closed radio mode;
in the closed radio mode, the first speaker 31 emits a first audio signal to the human ear, and the second speaker 32 is turned off; the human ear has a physical barrier between the ear and the outside (which may be understood as the external environment) for preventing leakage of the first audio signal to the external environment and for preventing the third audio signal from entering the human ear.
In this embodiment, when in the closed radio mode, a physical barrier is provided between the human ear and the external environment, and the physical barrier can prevent the first audio signal from leaking to the external environment and prevent the third audio signal from entering the human ear, so that the third audio signal can be isolated while avoiding sound leakage; the defect of the leakage sound is overcome by the physical barrier, and the second speaker 32 is turned off at this time to avoid forming an excessive sound signal to cause interference.
In addition, in the closed sound reception mode, the volume of the first speaker 31 is increased relative to that in the normal sound reception mode so that the user can clearly listen to the audio signal. For example, the volume of the first horn 31 may be adjusted to 1.2 times the volume of the headphone before switching, or to 60% of the default maximum volume (in the case where the volume before switching does not reach 60% of the default maximum volume). Based on the method, the self-adaptive adjustment of the volume can be realized, so that the user experience is effectively improved.
Referring to fig. 4, in the duration of the closed radio mode, the switching method further includes:
s21, acquiring a second switching parameter in a closed radio mode;
s22, when the second switching parameter meets the common sound receiving condition, the sound receiving mode of the earphone is switched to the common sound receiving mode.
When the second switching parameter meets the common sound receiving condition, the closed sound receiving mode is exited, and the sound receiving mode of the earphone is switched to the common sound receiving mode; when the normal sound receiving mode is switched back, the second speaker 32 operates normally again, and the second audio signal emitted by the second speaker corresponds to the first audio signal automatically.
In order to improve the user experience, when the normal sound receiving mode is switched back, the volume of the first loudspeaker 31 can be adjusted to a preset value, the volume value before entering the closed sound receiving mode, or 50% of the default maximum volume, etc. It will be appreciated that the preset value is preset by the user, and may be purely a volume value or a preset value of the equalizer. Based on the method, the earphone can be adaptively adjusted according to the habit of the user, so that the user experience is effectively improved.
Wherein the first switching parameter and the second switching parameter respectively include: the temperature, the light intensity, the air pressure, the pressure or the volume which are collected for the preset area of the earphone can be the combination of two or more of the temperature, the light intensity, the air pressure, the pressure and the volume.
The headset comprises a first microphone 41 for collecting human voice and a second microphone 42 for collecting a third audio signal; the mounting areas of the first microphone 41 and the second microphone 42 are each enclosed within a predetermined area; thus, the aforementioned sound volume is the human sound volume collected by the first microphone 41, or the ambient sound volume collected by the second microphone 42, or a weighted sum of the human sound volume and the ambient sound volume.
And a temperature sensor, a light sensor, an air pressure sensor and a pressure sensor can be arranged in a preset area on the earphone so as to collect other switching parameters.
In addition, when the change rate of the first switching parameter is larger than a preset first value, the closed radio condition is met;
and when the second switching parameter change rate is larger than a preset second value, the ordinary radio condition is satisfied.
In consideration of the fact that the user does not continuously sound, the probability of continuously existing sound in the environment is high, the second loudspeaker is used as the main part and the first loudspeaker is used as the auxiliary part in practical application, and therefore the effect of improving induction accuracy is achieved.
In one implementation manner of this embodiment, the conditions for the first switching parameter to be changed are specifically:
when a user acts on the earphone in a preset gesture to form a physical barrier, the switching parameters in the preset area of the earphone can be enabled to meet the closed radio condition.
Specifically, the gesture for switching the earphone to the closed radio mode includes:
The palm covers the human ear and the earphone, or the earphone is pressed to press the earphone to press the tragus.
The switching principle corresponding to different gestures is as follows:
When the user covers the human ear and the earphone with the palm, the temperature sensor on the earphone senses temperature change, and/or the air pressure sensor senses air pressure change in the auditory canal, and/or the light sensor senses light change, and/or at least the second microphone 42 senses volume change, and when at least one change meets the closed radio condition, the closed radio mode is switched; simultaneously, the palm covers outside the earphone, can form a physical barrier, and this physical barrier makes first audio signal can not reveal to the external environment, and third audio signal can not get into in the people's ear simultaneously to satisfy the user demand of closed radio reception.
When the earphone is pressed to enable the earphone to press the tragus, a temperature sensor on the earphone senses temperature change, and/or a pressure sensor senses pressure change, and/or a light sensor senses light change, and when the closed radio condition is met, the closed radio mode is switched; meanwhile, as the earphone extrudes the tragus to generate tight connection, the tight connection can form a physical barrier, so that the first audio signal cannot leak to the external environment, and the third audio signal cannot enter the human ear, thereby meeting the use requirement of closed radio reception.
When the user triggers the switch from the closed radio mode to the normal radio mode by pressing, the volume of the second microphone 42 and the change of the air pressure sensor are required to satisfy the closed radio condition at the same time, so that erroneous judgment can be avoided as much as possible.
In another implementation of this embodiment, the conditions under which the first switching parameter is changed are specifically:
When a user acts on a preset area of the earphone in a preset gesture, the first switching parameter meets a closed sound receiving condition;
the gestures include: touching a preset touch position on the earphone; wherein the touch position is located in a predetermined area.
When a preset touch position (the touch position corresponds to a setting area of a sensor or the position of a microphone) on the earphone is touched, a temperature sensor on the earphone senses temperature change, and/or a pressure sensor senses pressure change, and/or a light sensor senses light change, and/or at least a second microphone 42 senses volume change, and at least one change meets a closed sound receiving condition, switching to a closed sound receiving mode;
meanwhile, a barrier part capable of being controlled to be opened can be arranged on the earphone, and can be opened into a cover body covering the outside of the earphone when the barrier part is switched to a closed radio mode, so that a physical barrier is formed, the first audio signal cannot leak to the external environment, and meanwhile, the third audio signal cannot enter the human ear, and therefore the use requirement of closed radio is met.
It can be understood that two accommodating cavities which are arranged back to back can be arranged on the earphone, umbrella-shaped structures are respectively arranged in the two accommodating cavities, and the physical barrier can be formed by controlling the automatic opening of the umbrella-shaped structures.
In this embodiment, when the change value of at least one first switching parameter is greater than a preset first value, the closed radio condition is satisfied; because the trigger signal taken by the sensor is a short one-time transient change (equivalent to the process of 0 to 1 and then maintained at 1), a sudden change electric signal is obtained, and misjudgment is not easy.
When the change value of at least one second switching parameter is larger than a preset second value, the ordinary radio condition is satisfied.
When the palm covers the human ear and the earphone or the gesture of pressing the earphone to press the tragus is used as a switching condition from the closed sound receiving mode to the common sound receiving mode, the user needs to continuously cover the earphone or continuously press the earphone by the palm in the closed sound receiving process, and the change value of the air pressure, the light or the temperature is used as a switching judging condition of the common sound receiving mode, so that the accuracy is low (the process from 1 to 0 is not easy to detect);
In order to improve accuracy, in this embodiment, the change value of the volume is used as a switching judgment condition of the ordinary radio mode, so that the accuracy of judgment can be improved; the reason is that there is no input of an audio signal when the microphone is covered, and the microphone can immediately receive a signal of an environmental sound (equivalent to a process of 0 to 1, and then maintained at 1) after the cover is removed, so that erroneous judgment is not easy to occur.
Example two
Referring to fig. 5, based on the foregoing embodiment, the embodiment of the present invention further provides an earphone for implementing the method for switching the radio mode of the earphone according to the above embodiment.
Wherein the earpiece comprises a first horn 31 configured to emit a first audio signal to the ear canal and a second horn 32 configured to emit a second audio signal outside the ear. The outer ear has an open channel that allows a third audio signal (i.e., ambient sound) to pass into the ear canal; in the normal sound reception mode, the first audio signal and the second audio signal are generated synchronously so as to counteract the leakage of the first audio signal outside the ear.
The second audio signal is determined based on the first audio signal, specifically an audio signal obtained by performing time domain inversion according to the first audio signal; when the second audio signal is emitted to the external environment, the distance difference between the first loudspeaker 31 and the second loudspeaker 32 is smaller than the distance difference between the far fields, so that the part of the first audio signal leaked to the external environment can be well counteracted, and the purpose of avoiding sound leakage is achieved.
In this embodiment, the earphone further includes:
The parameter acquisition unit 20, the parameter acquisition unit 20 is used for acquiring a first switching parameter in a common radio mode;
The mode switching unit 10 is configured to:
When the first switching parameter meets the closed radio receiving condition, the radio receiving mode of the earphone is switched to the closed radio receiving mode.
In the closed radio mode, the first speaker 31 emits the first audio signal to the human ear, and the second speaker 32 is turned off, so that the first audio signal does not leak to the external environment under the action of the physical barrier.
Wherein the second audio signal is determined based on the first audio signal, specifically an audio signal obtained by performing time domain inversion according to the first audio signal; when the second audio signal is emitted to the external environment, the distance difference between the first loudspeaker 31 and the second loudspeaker 32 is smaller than the distance difference between the far fields, so that the part of the first audio signal leaked to the external environment can be well counteracted, and the purpose of avoiding sound leakage is achieved.
While in the closed radio mode, the first horn 31 emits a first audio signal to the human ear while the second horn 32 is closed; the human ear has a physical barrier between the ear and the outside (which may be understood as the external environment) for preventing leakage of the first audio signal to the external environment and for preventing the third audio signal from entering the human ear.
In this embodiment, when in the closed radio mode, a physical barrier is provided between the human ear and the external environment, and the physical barrier can prevent the first audio signal from leaking to the external environment and prevent the third audio signal from entering the human ear, so that the third audio signal can be isolated while avoiding sound leakage; the defect of the leakage sound is overcome by the physical barrier, and the second speaker 32 is turned off at this time to avoid forming an excessive sound signal to cause interference.
In addition, in the closed sound reception mode, the volume of the first speaker 31 is increased relative to that in the normal sound reception mode so that the user can clearly listen to the audio signal. For example, the volume of the first horn 31 may be adjusted to 1.2 times the volume of the headphone before switching, or to 60% of the default maximum volume (in the case where the volume before switching does not reach 60% of the default maximum volume).
Further, in the present embodiment, the first and second embodiments,
The parameter acquisition unit 20 is further configured to acquire a second switching parameter in the closed radio mode, and the mode switching unit 10 is further configured to switch the radio mode of the earphone to the normal radio mode when the second switching parameter meets the normal radio condition.
When the second switching parameter meets the common sound receiving condition, the closed sound receiving mode is exited, and the sound receiving mode of the earphone is switched to the common sound receiving mode; when the normal sound receiving mode is switched back, the second speaker 32 operates normally again, and the second audio signal emitted by the second speaker corresponds to the first audio signal automatically.
In order to improve the user experience, when the normal sound receiving mode is switched back, the sound volumes of the first loudspeaker 31 and the second loudspeaker 32 can be adjusted to a preset value, the sound volume value before entering the closed sound receiving mode, or 50% of the default maximum sound volume, etc. It is understood that the preset value may be preset by the user, may be purely a volume value, or may be a preset value of the equalizer.
Based on this, the parameter acquisition unit 20 is disposed in a predetermined area on the earphone, so as to match with the gesture of the user to realize the switching of the sound reception mode.
In this embodiment, the first switching parameter and the second switching parameter respectively include: the temperature, the light intensity, the air pressure, the pressure or the volume which are collected for the preset area of the earphone can be the combination of two or more of the temperature, the light intensity, the air pressure, the pressure and the volume. The preset area can be provided with a temperature sensor, a light sensor, a pressure sensor and a pressure sensor to collect other switching parameters.
In addition, the earphone includes a first microphone 41 for collecting human voice, and a second microphone 42 for collecting a third audio signal, and the predetermined area may further include setting positions of the first microphone 41 and the second microphone 42; therefore, the volume as the first switching parameter or the second switching parameter is the human voice volume collected by the first microphone 41, or the environmental volume collected by the second microphone 42, or a weighted sum of the human voice volume and the environmental volume.
In addition, when the change rate of the first switching parameter is larger than a preset first value, the closed radio condition is met; and when the second switching parameter change rate is larger than a preset second value, the ordinary radio condition is satisfied.
In consideration of the fact that the user does not continuously sound, the probability of continuously existing sound in the environment is high, the second loudspeaker can be used as a main part and the first loudspeaker can be used as an auxiliary part in practical application, and therefore the effect of improving induction accuracy is achieved.
In one implementation manner of this embodiment, the conditions for the first switching parameter to be changed are specifically:
When a user acts on the earphone in a preset gesture to form a physical barrier, the first switching parameter in a preset area of the earphone can be enabled to meet the closed radio condition.
Specifically, the gesture for switching the earphone to the closed radio mode includes:
The palm covers the human ear and the earphone, or the earphone is pressed to press the earphone to press the tragus.
The switching principle corresponding to different gestures is as follows:
When the user covers the human ear and the earphone, a temperature sensor on the earphone senses temperature change, and/or an air pressure sensor senses air pressure change in the auditory canal, and/or a light sensor senses light change, and/or at least a second microphone senses volume change, and when at least one change meets the closed radio condition, the closed radio mode is switched; simultaneously, the palm covers outside the earphone, can form a physical barrier, and this physical barrier makes first audio signal can not reveal to the external environment, and third audio signal can not get into in the people's ear simultaneously to satisfy the user demand of closed radio reception.
When the user triggers the switch of the closed radio mode by pressing, the volume of the second microphone 42 and the change of the air pressure sensor are required to meet the closed radio condition at the same time, so that erroneous judgment can be avoided as much as possible.
In another implementation of this embodiment, the conditions under which the first switching parameter is changed are specifically:
When a user acts on a preset area of the earphone in a preset gesture, the first switching parameter meets a closed sound receiving condition;
the gestures include: touching a preset touch position on the earphone; wherein the touch position is located in a predetermined area.
When a preset touch position (the touch position corresponds to a setting area of a sensor or the position of a microphone) on the earphone is touched, a temperature sensor on the earphone senses temperature change, and/or a pressure sensor senses pressure change, and/or a light sensor senses light change, and/or at least a second microphone senses volume change, and at least one change meets a closed sound receiving condition, switching to a closed sound receiving mode; meanwhile, a barrier part capable of being controlled to be opened can be arranged on the earphone, and can be opened into a cover body covering the outside of the earphone when the barrier part is switched to a closed radio mode, so that a physical barrier is formed, the first audio signal cannot leak to the external environment, and meanwhile, the third audio signal cannot enter the human ear, and therefore the use requirement of closed radio is met.
It can be understood that two accommodating cavities which are arranged back to back can be arranged on the earphone, umbrella-shaped structures are respectively arranged in the two accommodating cavities, and the physical barrier can be formed by controlling the automatic opening of the umbrella-shaped structures.
In addition, in this embodiment, when the change value of at least one first switching parameter is greater than a preset first value, the closed radio condition is satisfied; because the trigger signal taken by the sensor is a short one-time transient change (equivalent to the process of 0 to 1 and then maintained at 1), a sudden change electric signal is obtained, and misjudgment is not easy.
When the change value of at least one second switching parameter is larger than a preset second value, the ordinary radio condition is satisfied.
When the palm covers the human ear and the earphone or the gesture of pressing the earphone to press the tragus is used as a trigger to switch the closed sound receiving mode, the change value of the air pressure, the light or the temperature is used as a switching judging condition of the common sound receiving mode, so that the accuracy is low (the process from 1 to 0 is not easy to detect) in consideration of the fact that the user needs to continuously cover the earphone or continuously press the earphone in the closed sound receiving process;
In order to improve accuracy, in this embodiment, the change value of the volume is used as a switching judgment condition of the ordinary radio mode, so that the accuracy of judgment can be improved; the reason is that there is no input of an audio signal when the microphone is covered, and the microphone can immediately receive a signal of an environmental sound (equivalent to a process of 0 to 1, and then maintained at 1) after the cover is removed, so that erroneous judgment is not easy to occur.
The above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
