背景技术Background technique

具体实施方式Detailed ways
为了更清楚地说明本申请实施例或现有技术中的技术方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本申请保护的范围。In order to more clearly describe the technical solutions in the embodiments of the present application or the prior art, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described The embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.
本申请实施例提供一种音量调节方法，如图1所示，该方法可以包括：An embodiment of the present application provides a volume adjustment method. As shown in FIG. 1, the method may include:
S101、当耳机处于佩戴状态、且通过耳机播放音频时，通过耳机获取在播放音频时产生的当前耳道特征信息，以及通过设置在耳机上的声压传感器获取当前声压值。S101: When the earphone is in the wearing state and audio is played through the earphone, obtain the current ear canal characteristic information generated during audio playback through the earphone, and obtain the current sound pressure value through the sound pressure sensor provided on the earphone.
本申请实施例提供的一种音量调节方法适用于对耳机进行音量调节的场景，如手机对耳机音量进行自动调节，以及其他播放设备对耳机音量进行自动调节的场景。The volume adjustment method provided by the embodiment of the present application is suitable for scenarios where the volume of the earphone is adjusted, such as a scenario where the volume of the earphone is automatically adjusted by a mobile phone, and the volume of the earphone is automatically adjusted by other playback devices.
本申请实施例中，音量调节装置在和耳机通信后，检测耳机是否处于佩戴状态，当检测到耳机处于佩戴状态，并且通过耳机播放音频时，音量调节装置会获取耳机的当前耳道特征信息。In the embodiment of the present application, the volume adjustment device detects whether the earphone is in the wearing state after communicating with the earphone. When it is detected that the earphone is in the wearing state and audio is played through the earphone, the volume adjustment device obtains the current ear canal characteristic information of the earphone.
本申请实施例中，当耳机佩戴在耳廓不同位置时，耳道跟耳机构成的腔体特征存在差异，因此本申请实施例中的耳道特征信息是指用户在以不同的方式将耳机放入耳廓中佩戴时，用户耳道与耳机之间构成的腔体的特征。音量调节装置将当前用户耳道与耳机之间构成的腔体的特征作为当前耳道特征信息。In the embodiment of the present application, when the earphone is worn at different positions of the auricle, the characteristics of the cavity formed by the ear canal and the earphone are different. Therefore, the characteristic information of the ear canal in the embodiment of the present application means that the user puts the earphone in different ways. The characteristic of the cavity formed between the user’s ear canal and the earphone when worn in the auricle. The volume adjustment device uses the characteristics of the cavity formed between the ear canal of the current user and the earphone as the current ear canal characteristic information.
本申请实施例中，当不同用户使用耳机时，由于不同人耳的结构不同，因此不同用户即使同一佩戴方式佩戴耳机，耳道与耳机之间所形成的腔体也是不同的，即当不同用户使用耳机时，每个用户对应的耳道特征信息是不同的；另外，同一用户以不同佩戴方式佩戴耳机时， 示例性的，未佩戴方式、正常佩戴方式、比较紧的佩戴方式，比较松的佩戴方式，或随意位置的佩戴方式等，也会引起耳道与耳机之间所形成的腔体差异，因此当同一用户以不同佩戴方式佩戴耳机时，每种佩戴方式所对应的耳道特征信息也不同。因此耳道特征信息可以表征每个不同用户的每种不同的耳机佩戴方式，当前耳道特征信息表征当前用户对耳机当前的佩戴方式。In the embodiments of this application, when different users use earphones, because the structures of different human ears are different, the cavity formed between the ear canal and the earphone is different even if different users wear the earphone in the same way, that is, when different users When using earphones, each user’s corresponding ear canal characteristic information is different; in addition, when the same user wears earphones in different wearing methods, exemplarily, the non-wearing method, the normal wearing method, and the tighter wearing method are relatively loose. Wearing methods, or wearing methods at random positions, etc., will also cause differences in the cavity formed between the ear canal and the earphones. Therefore, when the same user wears the earphones in different wearing methods, the ear canal characteristic information corresponding to each wearing method Also different. Therefore, the ear canal feature information can represent each different earphone wearing mode of each different user, and the current ear canal feature information represents the current user's current wearing mode of the earphone.
在一些实施例中，音量调节装置通过耳机获取在播放音频时产生的当前耳道特征信息，以及通过设置在耳机上的声压传感器获取当前声压值之前，音量调节装置还可以执行S1011至S1013，来判断耳机是否处于佩戴状态，如下：In some embodiments, before the volume adjustment device obtains the current ear canal characteristic information generated when playing audio through the earphone, and obtains the current sound pressure value via the sound pressure sensor provided on the earphone, the volume adjustment device may also perform S1011 to S1013. , To determine whether the headset is in the wearing state, as follows:
S1011、当通过耳机播放音频时，通过耳机获取在播放音频时产生的初始耳道特征信息。S1011. When playing audio through the earphone, obtain the initial ear canal characteristic information generated when the audio is played through the earphone.
当通过耳机播放音频时，音量调节装置通过耳机获取在播放音频时产生的耳道特征信息，作为初始耳道特征信息。When the audio is played through the earphone, the volume adjustment device acquires the ear canal characteristic information generated when the audio is played through the earphone as the initial ear canal characteristic information.
本申请实施例中，当用户使用耳机听歌，看视频时，耳机会播放相应的音频，此时用户可能已经将耳机佩戴至耳廓内，这时用户可以正常收听对应的音频，也有可能用户并没有将耳机佩戴上就开始播放音频了。因此音量调节装置需要先判断耳机的佩戴状态。由于当耳机处于未佩戴、自由放置状态时，不存在耳机与耳道之间形成的腔体，因此耳机处于佩戴状态与耳机处于未佩戴状态所分别对应的耳道特征信息必然存在很大差异。音量调节装置可以通过获取耳机在播放音频时产生的初始耳道特征信息，判断出耳机是否处于佩戴状态。In the embodiments of this application, when the user listens to music and watches videos using headphones, the headphones will play the corresponding audio. At this time, the user may have worn the headphones inside the auricle. At this time, the user can listen to the corresponding audio normally, or the user may I started playing audio without putting on the headphones. Therefore, the volume adjustment device needs to first determine the wearing state of the headset. Since there is no cavity formed between the earphone and the ear canal when the earphone is in the unworn and freely placed state, the ear canal characteristic information corresponding to the earphone in the wearing state and the earphone in the unworn state must be very different. The volume adjustment device can determine whether the earphone is in the wearing state by acquiring the initial ear canal characteristic information generated when the earphone is playing audio.
本申请实施例中，初始耳道特征信息可以是音量调节装置在通过耳机播放音频时采集到的首个耳道特征信息，也可以是在通过耳机播放音频过程中，音量调节装置以预定时间间隔进行采集得到的耳道特征信息。这样，音量调节装置可以通过首个耳道特征信息判断在音频开始播放时耳机是否处于佩戴状态，也可以在音频播放过程中监测耳机是否被取下。In the embodiment of the present application, the initial ear canal characteristic information may be the first ear canal characteristic information collected by the volume adjustment device when playing audio through the earphone, or it may be the first ear canal characteristic information collected by the volume adjustment device during audio playback through the earphone. The characteristic information of the ear canal is collected. In this way, the volume adjustment device can determine whether the earphone is in a wearing state when the audio starts to be played based on the first ear canal characteristic information, and can also monitor whether the earphone is taken off during the audio playback.
S1012、计算初始耳道特征信息与预设耳道特征信息的第二匹配度。S1012. Calculate a second degree of matching between the initial ear canal feature information and the preset ear canal feature information.
本申请实施例中，音量调节装置会首先预设并保存未佩戴耳机时对应的耳道特征信息，作为预设耳道特征信息。In the embodiment of the present application, the volume adjustment device first presets and saves the corresponding ear canal characteristic information when the earphone is not worn, as the preset ear canal characteristic information.
本申请实施例中，在存在预设耳道特征信息的前提下，音量调节装置获取到初始耳道特征信息之后，会将初始耳道特征信息与表征未佩戴耳机状态的预设耳道特征信息进行对比和匹配，来判断当前耳机是否处于佩戴状态。In the embodiment of the present application, on the premise that there is preset ear canal feature information, after the volume adjustment device obtains the initial ear canal feature information, it will combine the initial ear canal feature information with the preset ear canal feature information representing the state of not wearing the earphone Perform comparison and matching to determine whether the current headset is in the wearing state.
本申请实施例中，音量调节装置会计算出初始耳道特征信息与预设耳道特征信息的第二匹配度，以第二匹配度作为判断的标准。In the embodiment of the present application, the volume adjustment device calculates the second matching degree between the initial ear canal characteristic information and the preset ear canal characteristic information, and the second matching degree is used as a criterion for judgment.
S1013、当第二匹配度大于预设第二匹配度阈值时，生成表征耳机处于未佩戴状态的告警提示。S1013: When the second matching degree is greater than the preset second matching degree threshold, generate an alarm prompt indicating that the headset is in an unworn state.
音量调节装置计算出初始耳道特征信息与预设耳道特征信息的第二匹配度之后，如果第二匹配度大于预设第二匹配度阈值，说明初始耳道特征信息与预设耳道特征信息即未佩戴状态所采集到的耳道特征信息非常接近，因此音量调节装置可以认为当前耳机处于未佩戴状态。After the volume adjustment device calculates the second matching degree between the initial ear canal feature information and the preset ear canal feature information, if the second matching degree is greater than the preset second matching degree threshold, the initial ear canal feature information and the preset ear canal feature are indicated The information, that is, the characteristic information of the ear canal collected in the unworn state is very close, so the volume adjustment device can consider that the current earphone is in the unworn state.
音量调节装置在判断耳机处于未佩戴状态后，由于未佩戴耳机时对音量进行调节是无意义的，因此音量调节装置生成表征耳机处于未佩戴状态的告警提示，并结束方法流程。After the volume adjustment device determines that the earphone is in the unworn state, since it is meaningless to adjust the volume when the earphone is not worn, the volume adjustment device generates an alarm prompt indicating that the earphone is in the unworn state, and ends the method flow.
在一些实施例中，告警提示可以是音量调节装置在终端显示界面上进行相应的提示，提示用户耳机未佩戴，或以警示音提示用户耳机处于未佩戴状态，具体的根据实际情况进行实现，本申请实施例不作限定。In some embodiments, the alarm prompt may be a corresponding prompt by the volume adjustment device on the terminal display interface, prompting the user that the headset is not worn, or prompting the user that the headset is not worn with a warning sound, which is specifically implemented according to actual conditions. The application examples are not limited.
可以理解的是，通过对初始耳道特征信息与预设耳道特征信息的匹配，音量调节装置可以实时监测耳机是否处于佩戴状态，并在耳机脱落、未佩戴时进行及时告警，提高了音量调节的智能性。It is understandable that by matching the initial ear canal characteristic information with the preset ear canal characteristic information, the volume adjustment device can monitor whether the earphone is in the wearing state in real time, and give a timely warning when the earphone is off or not worn, thereby improving the volume adjustment The intelligence.
本申请实施例中，音量调节装置在判断出耳机处于佩戴状态之后，当耳机播放音频时，音量调节装置通过耳机获取在播放音频时产生的当前耳道特征信息。In the embodiment of the present application, after the volume adjusting device determines that the earphone is in the wearing state, when the earphone is playing audio, the volume adjusting device obtains the current ear canal characteristic information generated during audio playback through the earphone.
在一些实施例中，当前耳道特征信息包括当前阻抗信息；音量调节装置通过耳机获取在播放音频时产生的当前耳道特征信息的方法可以包括：通过耳机播放音频时，基于耳机中的 数模转换电路，检测在播放音频时产生的电压信号和电流信号；依据耳机基于电压信号与所述电流信号，生成当前阻抗信息。In some embodiments, the current ear canal characteristic information includes current impedance information; the method for the volume adjusting device to obtain the current ear canal characteristic information generated when playing audio through the earphone may include: when playing audio through the earphone, based on the digital analog in the earphone The conversion circuit detects the voltage signal and the current signal generated during audio playback; according to the earphone, the current impedance information is generated based on the voltage signal and the current signal.
音量调节装置在确定耳机处于佩戴状态、且通过耳机播放音频时，向耳机发送阻抗检测指令，耳机响应于阻抗检测指令，利用设置在耳机左右声道中的电压数模转换电路和电流数模转换电路检测在播放音频时产生的电压信号和电流信号计算出耳道阻抗值，利用耳道阻抗值和所播放音频中频率生成一条阻抗曲线，即当前阻抗信息；其中，音频可以为扫频音。When determining that the earphone is in the wearing state and playing audio through the earphone, the volume adjustment device sends an impedance detection command to the earphone. The earphone responds to the impedance detection command by using the voltage digital-to-analog conversion circuit and current digital-to-analog conversion set in the left and right channels of the earphone. The circuit detects the voltage signal and current signal generated during audio playback to calculate the ear canal impedance value, and uses the ear canal impedance value and the frequency of the played audio to generate an impedance curve, that is, the current impedance information; among them, the audio can be a frequency sweep tone.
示例性地，耳机处于佩戴状态，通过耳机播放20HZ到20KHZ的扫频音源，以不同频率进行音频的播放，音量调节装置利用耳机中电流数模转换器检测在播放音频时产生的电流信号、以及利用电压数模转换器检测在播放音频时产生的电压信号，得到20HZ到20KHZ范围的音频播放频率内，不同音频频率下检测到的不同电流信号和电压信号。音量调节装置根据每种不同音源频率下测得的电压信号和电流信号，计算出每种不同频率对应的不同耳道阻抗值，并根据每种不同频率对应的不同耳道阻抗值，生成一条阻抗曲线，曲线中的每个点为每个音频频率下计算出的耳道阻抗值。音量调节装置将最后生成的阻抗曲线作为当前阻抗信息，音量调节装置将当前阻抗信息作为当前耳道特征信息。Exemplarily, the earphone is in the wearing state, the 20HZ to 20KHZ frequency sweeping audio source is played through the earphone, and the audio is played at different frequencies.

The volume adjustment device calculates the different ear canal impedance values corresponding to each different frequency according to the voltage signal and current signal measured under each different sound source frequency, and generates an impedance according to the different ear canal impedance values corresponding to each different frequency Curve, each point in the curve is the ear canal impedance value calculated at each audio frequency. The volume adjustment device uses the last generated impedance curve as current impedance information, and the volume adjustment device uses the current impedance information as current ear canal characteristic information.
需要说明的是，当耳机与耳道之间形成的腔体不同时，在同一音频频率下检测到的电压信号和电流信号是不同的，因此根据电压信号和电流信号计算得到的当前阻抗信息也不同，由于不同用户佩戴耳机，或者同一用户以不同佩戴方式佩戴耳机时都会产生腔体的不同，因此可以利用当前阻抗信息来区分不同的用户或同一用户不同的佩戴方式。It should be noted that when the cavity formed between the earphone and the ear canal is different, the voltage signal and current signal detected at the same audio frequency are different, so the current impedance information calculated based on the voltage signal and current signal is also different. Different, because different users wear earphones or the same user wears earphones in different ways, the cavities are different, so the current impedance information can be used to distinguish different users or different wearing ways of the same user.

需要说明的是，当耳道跟耳机所形成的腔体不同时，不同腔体对应的总时间差T不同，因此音量调节装置根据总时间差T生成的超声信息也不同，而由于不同用户佩戴耳机，或者同一用户以不同佩戴方式佩戴耳机时都会产生腔体的不同，因此可以利用超声信息区分不同的用户或者同一用户不同的佩戴方式；并且，由于超声波超出人耳听觉频率范围，用户无法感知，故获取超声信息的过程不会影响用户从耳机中收到人耳听觉频率范围内的音频。It should be noted that when the cavity formed by the ear canal and the earphone is different, the total time difference T corresponding to the different cavities is different, so the ultrasonic information generated by the volume adjustment device according to the total time difference T is also different, and because different users wear the earphone, Or when the same user wears earphones in different ways, the cavities will be different, so ultrasonic information can be used to distinguish different users or different wearing methods of the same user; and because the ultrasonic wave exceeds the frequency range of human ears, the user cannot perceive it. The process of acquiring ultrasound information will not affect the user's receiving of audio in the human ear's auditory frequency range from the headset.

When the error is less than or equal to the preset error threshold, When the error threshold is set, it means that the current ear canal feature information is very close to the reference ear canal feature information, because the reference sound pressure value corresponding to the reference ear canal feature information represents the most suitable sound for playing under the wearing mode corresponding to the reference ear canal feature information. The current ear canal characteristic information is very close to the reference ear canal characteristic information. Therefore, the volume adjustment device can use the reference sound pressure value to adjust the volume of the played audio.

Because V A1 is the best playback volume adjusted by the user in the wearing mode of E A1 during the previous collection process. Therefore, the volume adjustment device uses the reference sound pressure value V A1 to adjust the volume of the played audio to match the playback volume most suitable for the user in the current wearing mode.

For certain compensation or attenuation, the volume adjustment device uses the compensated or attenuated reference sound pressure value to adjust the volume of the played audio.
本申请实施例中，不同的耳道特征信息与声压值之间存在正比或反比的关系，示例性的，当耳道特征信息为阻抗信息时，耳道特征信息与声压值之间为反比关系，阻抗越大，声压值越小。因此，在当前耳道特征信息与参考耳道特征信息之间的误差超出预设误差阈值时，说明当前耳道特征信息与参考耳道特征信息之间的区别超出了最大区别度的限制，即当前耳道特征信息与参考耳道特征信息不够接近，不能直接使用参考声压值来调节播放音频的音量。音量调节装置可以继续判断当前耳道特征信息是否超出参考耳道特征信息预设误差阈值范围的上限或下限，当当前耳道特征信息超出参考耳道特征信息预设误差阈值范围的上限时，由于阻抗信息与声压值为反比关系，音量调节装置对参考声压值进行一定衰减，音量调节装置使用衰减后的参考声压值来调节播放音频的音量；同样的，当当前耳道特征信息超出参考耳道特征信息预设误差阈值范围的下限时，由于阻抗信息与声压值为反比关系，音量调节装置对参考声压值进行一定补偿，音量调节装置使用补偿后的参考声压值来调节播放音频的音量。其中，补偿或衰减的范围根据实际情况进行选择，本申请实施例不作限定。In the embodiments of this application, there is a proportional or inverse relationship between different ear canal characteristic information and sound pressure value. For example, when the ear canal characteristic information is impedance information, the difference between the ear canal characteristic information and the sound pressure value is Inversely proportional, the greater the impedance, the smaller the sound pressure value. Therefore, when the error between the current ear canal feature information and the reference ear canal feature information exceeds the preset error threshold, it means that the difference between the current ear canal feature information and the reference ear canal feature information exceeds the limit of the maximum difference, that is, The current ear canal feature information is not close enough to the reference ear canal feature information, and the reference sound pressure value cannot be used directly to adjust the volume of the played audio. The volume adjustment device can continue to determine whether the current ear canal feature information exceeds the upper or lower limit of the preset error threshold range of the reference ear canal feature information. When the current ear canal feature information exceeds the upper limit of the preset error threshold range of the reference ear canal feature information, because The impedance information is inversely proportional to the sound pressure value. The volume adjustment device attenuates the reference sound pressure value to a certain extent, and the volume adjustment device uses the attenuated reference sound pressure value to adjust the volume of the played audio; similarly, when the current ear canal characteristic information exceeds When the lower limit of the error threshold range is preset with reference to the characteristic information of the ear canal, since the impedance information and the sound pressure value are inversely proportional, the volume adjustment device compensates the reference sound pressure value to a certain extent, and the volume adjustment device uses the compensated reference sound pressure value to adjust The volume of the audio being played. The range of compensation or attenuation is selected according to actual conditions, which is not limited in the embodiment of the present application.
本申请实施例中，预设误差阈值范围的上限为以参考耳道特征信息为基准，向上浮动的预设误差阈值，预设误差阈值范围的下限为以参考耳道特征信息为基准，向下浮动的预设误差阈值。In the embodiment of the present application, the upper limit of the preset error threshold range is the preset error threshold floating upward based on the reference ear canal feature information, and the lower limit of the preset error threshold range is based on the reference ear canal feature information, downward Floating preset error threshold.
在一些实施例中，音量调节装置在确定E A1为参考耳道特征信息，以及V A1为参考声压值之后，音量调节装置计算当前耳道特征信息E和参考耳道特征信息E A1之间的误差，当误差大于预设误差阈值时，说明参考耳道特征信息E A1虽然是全部采集过的耳道特征信息中与当前耳道特征信息E最接近的一个，但是两者的近似度还是不够高，不能直接以参考声压值输出，而是要在参考声压值的基础上进行相应的衰减或补偿再进行输出。音量调节装置可以为参考耳道特征信息预设误差阈值范围，示例性的，当耳道特征信息为阻抗信息时，音量调节装置可以为参考耳道特征信息预设 ±5的预设误差阈值范围，当当前耳道特征信息E超出参考耳道特征信息E A1+5的上限时，说明当前的佩戴方式比参考耳道特征信息对应的佩戴方式阻抗更大，根据阻抗信息和声压值的反比关系，目标音量值应比参考声压值更低，因此音量调节装置对参考声压值V A1进行一定的衰减；同理，当当前耳道特征信息E超出参考耳道特征信息E A1-5的下限时，音量调节装置根据阻抗信息和声压值的反比关系，对参考声压值V A1进行一定补偿，以起到根据参考声压值智能调整音频播放音量的作用。 In some embodiments, after the volume adjustment device determines that E A1 is the reference ear canal feature information and V A1 is the reference sound pressure value, the volume adjustment device calculates the difference between the current ear canal feature information E and the reference ear canal feature information E A1 When the error is greater than the preset error threshold, it means that although the reference ear canal feature information E A1 is the closest one among all the collected ear canal feature information to the current ear canal feature information E, the degree of similarity between the two is still If it is not high enough, it cannot be output directly at the reference sound pressure value, but should be attenuated or compensated based on the reference sound pressure value before outputting. The volume adjusting device may preset an error threshold range for the reference ear canal feature information. For example, when the ear canal feature information is impedance information, the volume adjusting device may preset a preset error threshold range of ± 5 for the reference ear canal feature information , When the current ear canal feature information E exceeds the upper limit of the reference ear canal feature information E A1 +5, it means that the current wearing mode has greater impedance than the wearing mode corresponding to the reference ear canal feature information. According to the inverse ratio of the impedance information and the sound pressure value Relationship, the target volume value should be lower than the reference sound pressure value, so the volume adjustment device attenuates the reference sound pressure value V A1 to a certain extent; in the same way, when the current ear canal feature information E exceeds the reference ear canal feature information E A1 -5 When the lower limit of, the volume adjustment device compensates the reference sound pressure value V A1 according to the inverse relationship between the impedance information and the sound pressure value, so as to intelligently adjust the audio playback volume according to the reference sound pressure value.
可以理解的是，音量调节装置预先记录并保存耳道特征信息和声压值的对应关系，从而获得了每种不同佩戴方式下最适合播放的声压值，在使用耳机播放音频时，音量调节装置再获取当前耳道特征信息，将当前耳道特征信息与对应关系中的耳道特征信息进行匹配，从而得到参考声压值，并根据参考声压值调节播放音频的音量。使用本申请实施例提供的方法，可以根据不同的耳机佩戴方式自动匹配出最适合播放的音量值，提高了个性化使用耳机的智能性。It is understandable that the volume adjustment device pre-records and saves the corresponding relationship between the ear canal characteristic information and the sound pressure value, so as to obtain the sound pressure value most suitable for playback in each different wearing mode. When using headphones to play audio, adjust the volume The device then obtains the current ear canal feature information, matches the current ear canal feature information with the ear canal feature information in the corresponding relationship to obtain the reference sound pressure value, and adjusts the volume of the played audio according to the reference sound pressure value. Using the method provided in the embodiments of the present application, the most suitable volume value for playback can be automatically matched according to different earphone wearing modes, which improves the intelligence of personalized earphones.
