Detailed Description
Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. These embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein.
Fig. 1 is a schematic flowchart illustrating an audio playback mode switching method according to an embodiment of the present application, and referring to fig. 1, the audio playback mode switching method according to the embodiment of the present application is applied to a head-mounted device with earphones and speakers, and specifically includes the following steps S110 to S130:
step S110 is to detect the wearing states of the earphones on the left and right sides of the head set.
The audio playing mode switching method in the embodiment of the present application is mainly applied to a head-mounted device with an earphone and a speaker, where the head-mounted device may be any one of a virtual reality device, an augmented reality device, or a mixed reality device, and is not limited specifically herein.
For the head-mounted device provided with the earphone and the speaker at the same time, the corresponding audio playing mode may be an earphone playing mode and a speaker playing mode, and before determining whether to switch the audio playing mode of the head-mounted device, the wearing state of the earphone may be detected first, and a specific detection method may be flexibly set by a person skilled in the art according to the actual situation, for example, a pressure sensor is used to detect a pressure value of the earphone contacting with the human ear to determine the wearing state, or a capacitance sensor is used to detect a capacitance value of the earphone contacting with the human ear to determine the wearing state, and the like, which are not listed herein.
It should be noted that, in the embodiment of the present application, the detection of the wearing state of the earphones is performed separately for each earphone in the head set, and the detection results of the wearing states of the earphones on both sides are mutually incoherent. Likewise, the switching to the subsequent audio playback mode is also performed separately for each headphone.
And step S120, when the wearing state of the earphone on one side or the left side and the right side is detected to be the wearing state, controlling the audio channel on the same side as the wearing earphone to be switched to an earphone playing mode.
Step S130, when it is detected that the wearing state of the earphone on one side or both sides is taken off, controlling the audio channel on the same side as the taken-off earphone to switch to the speaker playing mode.
The wearing state of the earphones can be specifically divided into two types of wearing and taking off, and the wearing condition that the earphones on two sides can form can be as follows: 1) the earphones on the two sides are worn; 2) both earphones are taken off; 3) one side of the earphone is worn and the other side of the earphone is taken off.
For the above situation 1), when detecting that the earphones on both sides of the head-mounted device are both in the on-state, the audio channels of the earphones on both sides can be automatically switched to the earphone playing mode, and then a better audio playing effect can be provided for the user wearing the head-mounted device.
For the case of the above 2), when it is detected that the earphones on both sides of the head-mounted device are in the off state, the audio channels of the earphones on both sides can be automatically switched to the speaker playing mode, so that the user wearing the head-mounted device can hear external sound, and the user not wearing the head-mounted device can hear audio playing content.
For the above situation 3), when it is detected that the earphone on one side of the headset is worn and the earphone on the other side of the headset is removed, the audio channel of the worn earphone can be automatically switched to the earphone playing mode, and the audio channel of the removed earphone can be automatically switched to the speaker playing mode. For example, the user is when driving or crossing the road, can not hear external sound if both sides are all worn the earphone, for guaranteeing safety, can take off the earphone of one side and get external sound, only wear the earphone of opposite side, the earphone of wearing the upside at this moment continues to broadcast the audio frequency, and takes the side to switch into speaker broadcast audio frequency, can guarantee the broadcast effect like this, also can guarantee safety, has improved user experience greatly. For another example, in a conference scene, if the user wears the earphones on both sides of the ears, the user cannot hear the speech of other participants clearly, in order to ensure the conference effect, the earphone on one side can be taken off to listen to the speech of other participants, only the earphone on the other side is worn, the earphone on the upper side is worn to continue playing the audio, and the earphone on the lower side is taken off to be switched to the loudspeaker to play the audio, so that the participants who do not wear the head-mounted device can hear the sound of the device, each participant does not need to wear the head-mounted device, the user experience is improved, the conference effect can be ensured, and the conference efficiency is improved.
Therefore, the audio playing mode switching method can automatically switch the audio playing mode, complex operation that a user manually switches an audio channel is omitted, the continuity of sound output is kept, meanwhile, the use requirements of the user in different application scenes can be met, and user experience is greatly improved.
In one embodiment of the present application, the method further comprises: when the audio channel on the same side as the worn earphone is controlled to be switched to an earphone playing mode, the current volume of the earphone is zoomed according to a first proportional parameter; and when the audio channel on the same side with the picked-off earphone is controlled to be switched to a loudspeaker playing mode, zooming the current volume of the loudspeaker according to the second proportional parameter.
In order to ensure the switching effect and reduce the sense of incongruity, the embodiment of the application can also adjust the current volume of the earphone or the loudspeaker after the audio channel is switched according to different proportional parameters so as to ensure that the volumes received by human ears before and after the audio channel is switched are the same, thereby saving the operation of manually adjusting the volume by a user and improving the listening experience of the user.
For example, when the audio channel of the earphone is switched to the earphone playing mode, the current volume of the earphone can be adjusted according to the first proportional parameter, so that the volume of the audio signal output by the adjusted earphone is the same as the volume of the audio signal output by the speaker before adjustment when the audio signal reaches the ears of the person on the same side; for another example, when the audio channel of the earphone is switched to the speaker playing mode, the current volume of the speaker may be adjusted according to the second proportional parameter, so that the volume of the audio signal output by the adjusted speaker is the same as the volume of the audio signal output by the earphone before adjustment when the audio signal reaches the ear of the person on the same side.
In an embodiment of the present application, the obtaining steps of the first proportional parameter and the second proportional parameter are as follows: acquiring a head-mounted position of the head-mounted equipment in a wearing state; acquiring the distance from a loudspeaker on the same side as the worn earphone to the ear on the same side and the distance from the worn earphone to the eardrum of the ear on the same side according to the wearing position of the head-mounted equipment; determining a first proportional parameter required by the fact that the volume of an audio signal output by an earphone after the audio channel is switched is the same as the volume of an audio signal output by a loudspeaker before the audio channel is switched when the audio signal reaches the human ears on the same side by using a sound attenuation model according to the acquired distance from the loudspeaker to the human ears on the same side; and determining a second proportion parameter required by the fact that the volume of the audio signal output by the loudspeaker after the audio channel is switched is the same as the volume of the audio signal output by the earphone before the audio channel is switched when the audio signal reaches the ear of the person on the same side by using a sound attenuation model according to the acquired distance from the worn earphone to the eardrum of the person on the same side.
Specifically, the obtaining step for the first scale parameter may be: after the user wears the head-mounted device, the pressure sensor of the head-mounted device can detect the pressure value, and after the user adjusts the head-mounted position, the pressure value detected by the pressure sensor can be larger than the pressure value threshold value of the head-mounted device which is set in advance, and the user can be considered to wear the head-mounted device at the moment. When the fact that the user wears the headset of the headset is detected, the distance from the loudspeaker on the same side of the worn headset to the human ear on the same side is obtained according to the wearing position of the headset, and then the volume of the audio signal output by the loudspeaker when the audio signal reaches the human ear on the same side can be calculated through the sound attenuation model according to the obtained distance from the loudspeaker to the human ear on the same side. In order to ensure the listening experience of a user and avoid the situation that the user needs to manually adjust the volume after the audio channel is switched, the embodiment of the application restrains that the volume of the audio signal output by the earphone after the audio channel is switched when the audio signal reaches the eardrum is as equal as possible to the volume of the audio signal output by the loudspeaker before the audio signal is switched when the audio signal reaches the eardrum of the same side, and based on the constraint condition and in combination with the distance from the earphone to the eardrum of the same side, the target volume which the earphone should output after the switching can be calculated, the first proportional parameter can be calculated according to the target volume of the earphone and the current volume of the earphone, the current volume of the earphone is adjusted through the first proportional parameter, and then can guarantee that the volume of volume after adjusting when reaching the eardrum is the same with the volume that the speaker passed to people's ear before switching, has saved the operation that the user adjusted the earphone volume manually, has improved user experience.
In a similar way, for the acquisition of the second proportional parameter, the volume of the audio signal output by the earphone when reaching the eardrum of the ear on the same side can be calculated by utilizing the sound attenuation model according to the distance between the earphone worn and the eardrum of the ear on the same side, the target volume which the loudspeaker should output can be calculated according to the volume of the audio signal output by the earphone when the audio signal reaches the eardrum of the ear on the same side and the distance between the loudspeaker on the same side as the earphone and the ear on the same side, the second proportional parameter can be calculated according to the target volume of the loudspeaker and the current volume of the loudspeaker, the current volume of the loudspeaker is adjusted through the second proportional parameter, and then can guarantee that the volume of the volume after adjusting when reaching the human ear is the same with the volume that the earphone reaches the eardrum before switching, has saved the operation that the user adjusted the speaker volume manually, has improved user experience.
In one embodiment of the present application, the calculation formula of the sound attenuation model is:
Lp=Lw-K+DIm-Ae， （1）
wherein Lw is the volume corresponding to the audio signal output by the speaker, Lp is the volume of the audio signal output by the speaker when the audio signal reaches the ear of the same side, DIm is a directivity factor, Ae is other additional attenuation, K is a divergent attenuation value, and the calculation formula of the divergent attenuation value K is as follows:
K=10log(10,4π)+20log(10,r)，（2）
wherein r is the distance from the speaker to the ear on the same side.
The directivity factor DIm in the embodiment of the present application means whether there is a reflection surface near the sound source (considered separately on the ground), or the sound source itself is not a point sound source, and if one reflection surface is added, the magnitude of the directivity factor is increased by 3 dB. Other additional attenuations Ae may include in particular: air absorption Aa (related to frequency, air pressure, temperature, humidity, etc.), obstacle added attenuation Abhp, ground added attenuation Ag, and weather added attenuation Am, etc. Those skilled in the art can flexibly determine the size of each index according to a specific application scenario of the head-mounted device, and is not limited specifically herein.
When calculating the target output volume of the headphone based on the sound attenuation model, the target output volume can be estimated specifically as follows:
Lp1(volume of audio signal output from speaker when it reaches ear on same side) = Lw1(actual output volume of speaker) -10log (10,4 pi) -20log (10, r)1)（r1The distance from the loudspeaker to the ear on the same side) + DIm-Ae, (3)
Due to Lw1(actual output volume of speaker) and r1(distance from the speaker to the ear on the same side) is a known quantity, so Lp can be obtained by equation (3)1(volume of audio signal output by speaker arriving at the same side of ear)。
To improve the user's listening experience, Lp obtained as described above may be required here1(volume of audio signal output from speaker when it reaches ear on same side) = Lp2(volume of audio signal output from earphone when it reaches eardrum of the same side of ear)
Then according to the following formula:
Lp2(volume of audio signal output from headphone reaching eardrum of the same side of human ear) = Lw2(target output volume of earphone) -10log (10,4 pi) -20log (10, r)2)（r2The distance from the earphone to the eardrum of the same side of the human ear) + DIm-Ae, (4)
Due to Lp2(volume of audio signal output from headphone when it reaches eardrum of ear on the same side) is obtained in the above equation (3), r2(distance from the earphone to the eardrum of the same side of the human ear) is a known quantity, from which Lw can be deduced2(target earphone output volume).
After the user wears the head-mounted device, the distance from the speaker to the ear on the same side and the distance from the earphone to the eardrum are usually fixed, so the step of obtaining the first proportional parameter and the second proportional parameter may be to obtain the distance from the speaker to the ear on the same side and the distance from the earphone to the eardrum through a large number of experimental tests before the device leaves a factory, then to calculate the first proportional parameter and the second proportional parameter respectively by combining with the sound attenuation model, and to pre-store the calculated first proportional parameter and the calculated second proportional parameter in the head-mounted device for direct calling during subsequent use, thereby saving a certain calculation time.
Of course, in order to improve the accuracy of the calculation of the ratio parameter and meet the auditory requirements of different users, the steps of obtaining the first ratio parameter and the second ratio parameter in the embodiment of the present application may also be calculated in real time during the process of wearing the head-mounted device by the user. For example, for obtaining the first proportional parameter, after the user wears the head-mounted device, the distance between the speaker and the human ear is detected in real time according to the distance sensor arranged at the position of the speaker, and then the first proportional parameter is calculated in real time by combining the sound attenuation model. For the acquisition of the second proportional parameter, after the user wears the head-mounted device, the distance between the earphone and the eardrum of the human ear is detected in real time according to the distance sensor arranged at the position of the soft membrane of the earphone, and then the second proportional parameter is calculated in real time by combining the sound attenuation model.
In addition to the above-mentioned obtaining manner, the first scaling factor and the second scaling factor may also be a fixed value set in advance, or different scaling factors set for different sound volumes, for example, the current sound volume is 10dB, the corresponding scaling factor is set to 0.5, the current sound volume is 15dB, the corresponding scaling factor is set to 0.6, and so on. Specifically, how to obtain the first proportional parameter and the second proportional parameter may be flexibly set by a person skilled in the art according to an actual situation, and is not specifically limited herein.
In one embodiment of the present application, the method further comprises: responding to the identified first current application scene, and controlling the audio channels on the left side and the right side to be switched to an earphone playing mode and a loudspeaker playing mode simultaneously when detecting that the wearing states of the earphones on the left side and the right side are both worn; or, in response to the identified second current application scene, when it is detected that the wearing states of the earphones on the left and right sides are both worn, controlling the audio channel on one side to be switched to the earphone playing mode, and controlling the audio channel on the other side to be closed.
It is mainly considered that in some special scenes, the audio playing mode of the headset simply depending on the wearing state of the headset cannot meet the actual requirements of users. For example, when the current application scene is an outdoor sport scene, for example, it is detected that the user is in a walking or running state through an acceleration sensor built in the headset, at this time, even if it is detected that the earphones on both sides of the headset are in a wearing state, one of the earphones on both sides can be controlled to adopt an earphone playing mode, and the earphone on the other side is in a closed state, so that it can be ensured that the user obtains external sound through the earphone on one side in the closed state, and the safety of the user in the walking or running state is ensured.
For another example, when the current application scene is a conference scene, for example, the sound sensor identifies an environmental sound, the identified environmental sound is compared with a prestored environmental sound, and when the prestored environmental sound is satisfied, the current application scene is considered as the conference scene, and at this time, the audio playing mode of the earphone may also be controlled in accordance with the user usage requirement of the conference scene. Or the camera arranged on the head-mounted equipment can be used for capturing the image of the surrounding environment, detecting and identifying the image of the surrounding environment, determining the specific application environment of the head-mounted equipment according to the identification result, and further determining the corresponding audio playing mode switching mode according to the specific application environment and the wearing state of the earphone.
Specifically, how to determine the audio playing mode according to the application scenario and the wearing state of the headset is a technical person in the art can flexibly set the audio playing mode according to actual requirements, and the audio playing mode is not specifically limited herein.
In one embodiment of the present application, the detecting the wearing states of the earphones on the left and right sides of the head-mounted device respectively includes: for the earphones on any side, detecting the distance from the earphones to the eardrum by using a distance sensor arranged at the top end of the earphones; comparing the distance from the headset to the eardrum with a distance threshold, wherein the distance threshold comprises a first distance threshold and a second distance threshold, and the first distance threshold is less than the second distance threshold; when the distance from the earphone to the eardrum is smaller than a first distance threshold value, or the distance from the earphone to the eardrum is larger than a second distance threshold value, waking up a plurality of pressure sensors arranged on a soft membrane of the earphone, and respectively detecting the pressure values of the earphone and the human ear by utilizing the plurality of pressure sensors; when the distance from the earphone to the eardrum is smaller than a first distance threshold value and the pressure values detected by all the pressure sensors are larger than a pressure value threshold value, determining that the wearing state of the earphone is wearing; when the distance from the earphone to the eardrum is larger than a second distance threshold value and the pressure values detected by all the pressure sensors are not larger than a pressure value threshold value, determining that the wearing state of the earphone is taken off; and closing all the pressure sensors after the wearing state of the earphone is determined.
According to the embodiment of the application, the distance sensor and the pressure sensor can be respectively arranged on each earphone to detect the wearing state of each earphone. Fig. 2 is a schematic plan view of an in-ear headphone for illustrating the arrangement positions of a distance sensor and a pressure sensor in the headphone. Where a indicates the position of the top of the earphone and B1 and B2 indicate the positions of the soft membrane of the earphone, which is in contact with the human ear when the earphone is worn. The distance sensor is preferably located at position a and the pressure sensor is preferably located around the perimeter of the earpiece dome, for example at positions B1 and B2 of fig. 2.
As shown in fig. 3, for detecting that the earphone is worn, for the earphone on either side, a distance sensor is provided on the side of the top end of the earphone close to the eardrum, and the distance from the earphone to the eardrum can be detected by the distance sensor, and when the distance from the earphone to the eardrum is detected to be lower than a preset smaller distance threshold value a1, the distance from the earphone to the eardrum is considered to be very close, and the user is likely to be ready to wear the earphone. In order to improve the detection accuracy, the pressure sensors may be combined to further determine that the pressure sensors are awakened when the distance from the earphone to the eardrum is detected to be lower than a preset smaller distance threshold, the pressure sensors disposed on the eardrum are all compared with a preset pressure threshold b, and when the pressure values detected by all the pressure sensors exceed the pressure threshold b, the earphone may be considered to be worn and all the pressure sensors may be turned off.
As shown in fig. 4, for the detection that the earphone is in the detached state, the distance from the earphone to the eardrum may also be detected by the distance sensor at the top end of the earphone, and when the distance from the earphone to the eardrum is detected to be higher than a preset larger distance threshold value a2, it is considered that the distance from the earphone to the eardrum is far, and the user is likely to have detached the earphone. In order to improve the detection accuracy, the earphone can be further judged by combining the pressure sensors, namely when the distance from the earphone to the eardrum is detected to be higher than a preset larger distance threshold, the pressure sensors arranged on the soft membrane of the earphone are awakened, the pressure value detected by each pressure sensor is compared with a preset pressure value threshold b, and when the pressure values detected by all the pressure sensors do not exceed the pressure value threshold b, the earphone can be considered to be detached at the moment, and all the pressure sensors are closed.
It should be noted that the number of the pressure sensors in the embodiment of the present application should be not less than 2, so as to avoid false detection. The pressure sensors are in a sleep state in a normal state, and when the distance detector detects that the distance from the earphone to the eardrum is smaller than a first distance threshold or larger than a second distance threshold, the pressure sensors are awakened, the wearing state of the earphone is detected by using the pressure values detected by the pressure sensors, and after the wearing state of the earphone is determined, the pressure sensors are closed, so that the purpose of saving electricity can be achieved.
Pressure sensor in this application embodiment also can replace for capacitive sensor, detects the capacitance value that earphone and people's ear contacted through a plurality of capacitive sensor, compares the capacitance value that detects with the capacitance value threshold value, can detect out the wearing state of earphone equally. Therefore, the wearing state of the earphone is detected by specifically adopting what manner, and the technical personnel in the field can flexibly set according to the actual situation, which is not listed here.
