Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Referring to fig. 1, in an embodiment of the present application, a method for adjusting loudness and gain of headphones is provided, where the headphones include a left headphone and a right headphone, and the method includes the following steps:
step S1, playing a single-frequency signal through the left earphone and the right earphone;
step S2, respectively obtaining the air pressure value corresponding to the ear canal when the left earphone and the right earphone are played or the voltage value corresponding to the single-frequency signal played in the earphone when the playing stopping instruction is received;
step S3, calculating the loudness gain difference of the left earphone and the right earphone according to the air pressure value or the voltage value;
and step S4, adjusting the loudness of the left earphone and the right earphone according to the loudness gain difference value of the left earphone and the right earphone.
In this embodiment, since some users have hearing impairment or the left and right ear sensitivities are different, it is obvious that for this type of users, the left and right earphones need to be adjusted to different loudness gains.
Specifically, as stated in step S1, when the earphone is worn on the ear of the user, the single-frequency signal is played through the left earphone and the right earphone, and since the single-frequency signal is played in the ear of the user, the air pressure in the ear canal of the user is prompted to change, that is, the air pressure in the ear canal can feed back the single-frequency signal; or the single-frequency signal can stimulate the hearing of the user, and the user can actively feed back according to the hearing of the user. As described in the step S2, when the single-frequency signals are different, the feedback generated for the single-frequency signals is also different, and the air pressure values in the ear canals corresponding to the left earphone and the right earphone at this time are obtained according to the different feedback for the single-frequency signals; or when the user actively stops playing the single-frequency signal, acquiring the voltage values of the single-frequency signals played in the corresponding left earphone and the right earphone. It can be understood that, because the left ear and the right ear of the user are different, the generated air pressure changes differently under the stimulation of the same single-frequency signal, and therefore the difference between the left ear and the right ear can be obtained according to the difference between the air pressures in the two ear canals. Similarly, if the sensitivity of the user to the single-frequency signals with different voltage values is different, the difference between the left ear and the right ear can be obtained from the difference of the voltage values. Further, as described in the above steps S3-S4, the loudness gain difference between the left earphone and the right earphone can be calculated according to the difference between the air pressure value and the voltage value, and the loudness of the left earphone and the right earphone is adjusted according to the loudness gain difference between the left earphone and the right earphone. Thereby make left earphone and right earphone can adopt different gains to adjust, rationally adjust the loudness of left earphone and right earphone more to be applicable to user's actual demand more. That is, in the present embodiment, when adjusting the loudness of the left headphone and the right headphone, the adjustment needs to be performed according to the sensitivity difference of the user to the sound, rather than according to the playing volume of the current left headphone and the current right headphone. For example, when the left ear is sensitive, the loudness gain of the left ear is smaller than that of the right ear.
Specifically, in one embodiment, the front cavities of the left earphone and the right earphone are both provided with air pressure sensors; the air pressure sensor is used for detecting air pressure in the auditory canal.
Specifically, when the left headphone or the right headphone plays a single-frequency signal with electric power w, the sound pressure at a certain time is P.
Wherein the content of the first and second substances,
；
wherein the content of the first and second substances,
the voice volume is a constant, Lp is the sound pressure level, and the auditory characteristic of the human ear is a logarithmic characteristic, so that the voice volume is expressed logarithmically, and the voice volume is more consistent with the auditory habit of distinguishing the change of the voice volume by the human ear.
When the earphone is worn on the ear of a user, the earphone plays a single-frequency signal to generate vibration on the eardrum of the user, but the vibration of the eardrum cannot be directly measured, and the vibration of the eardrum can influence the air pressure change in the ear canal; therefore, the sound pressure in the auditory canal (namely, the air pressure of the air in the auditory canal after the sound wave interference) can be measured by measuring the air pressure in the auditory canal, and the difference value of the air pressure in the two auditory canals is equal to the difference value of the sound pressure in the two auditory canals; meanwhile, since the loudness gain is in accordance with the sound pressure, that is, the gain value is in accordance with the sound pressure value (only in different units), when performing the loudness gain, in order to make the left and right ear sounds consistent, the gain difference should be equal to the sound pressure difference.
Specifically, in an embodiment, the voltage values of the single-frequency signals played in the left earphone and the right earphone are adjustable, and preferably, the voltage values are gradually increased in an actual adjusting process.
In particular, the amount of the solvent to be used,
；
r is the direct current resistance of a loudspeaker in the earphone and is a constant;
wherein the content of the first and second substances,
is a constant, and Lw is the power level of the earphone;
it can be known from the above that, the power difference of the two earphones depends on the voltage of the single-frequency signal played in the two earphones, and because the left ear and the right ear of the user have different sensitivities to sounds with different powers, the difference of the two ears can be determined according to the voltage value of the current single-frequency signal, so as to determine the loudness gain difference of the two ears.
In this embodiment, it is noted that, at present, it is generally adopted to directly measure the loudness of the left earphone and the right earphone, so as to adjust the loudness gain. However, in this process, the characteristics of the user's ears are ignored, the sensitivities of the user's left ear and right ear are not exactly the same, and sounds with the same loudness may have different sensory experiences for the user. Therefore, in this embodiment, from the perspective of the user, the sensitivity difference of the left ear and the right ear of the user to the single-frequency signal is obtained, so as to calculate the loudness gain difference between the left earphone and the right earphone; it will be appreciated that the more sensitive the human ear, the lower the corresponding loudness gain should be.
The step S1 of playing a single frequency signal through the left earphone and the right earphone includes:
step S101, respectively playing single-frequency signals with set duration and set voltage values through the left earphone and the right earphone;
step S2 of respectively obtaining the air pressure value in the corresponding ear canal when the left earphone and the right earphone are played or the voltage value of the single-frequency signal played in the corresponding earphone when the playing stopping instruction is received includes:
step S102, detecting air pressure values in the set time length in the corresponding auditory canals through air pressure sensors respectively arranged in front cavities of the left earphone and the right earphone, and respectively calculating air pressure mean values in the set time length, namely a left ear air pressure mean value and a right ear air pressure mean value;
the step S3 of calculating the loudness gain difference between the left earphone and the right earphone according to the air pressure value or the voltage value includes:
step S103, comparing the air pressure difference values of the left ear air pressure mean value and the right ear air pressure mean value;
and step S104, calculating loudness gain difference values of the left earphone and the right earphone according to the air pressure difference value.
In this embodiment, when the earphone is worn on an ear of a person and is in an on state, the left earphone and the right earphone play a single-frequency signal (e.g., a single-frequency signal with a duration of 0.5 second and 1000 Hz) with a set time length and a set voltage value V, at this time, the air pressure sensors built in the left earphone and the right earphone can pick up the air pressure mean values in the ear canal corresponding to the set time period (e.g., within 0.5 second), which are the left ear air pressure mean value AL and the right ear air pressure mean value AR, respectively, compare the left ear air pressure mean value and the right ear air pressure mean value, and if AL-AR = c, control the total loudness gain reduction c of the left earphone in the earphone; otherwise, the same descriptions are omitted here. It should be understood that the voltage value V is a value determined by taking as a standard that a single frequency signal (for example, a single frequency signal with a duration of 0.5 second at 1000 Hz) is not annoying when a human ear wears the earphone.
In this embodiment, before the step S1 of playing a single frequency signal through the left earphone and the right earphone, the method includes:
step Sa, detecting the air pressure value in the corresponding auditory canal through air pressure sensors respectively arranged in the front cavities of the left earphone and the right earphone;
step Sb, judging whether the air pressure value is larger than a threshold value or not;
and step Sc, if the current time is greater than the preset time, controlling the earphone to be started.
In this embodiment, by adding the air pressure sensor to the front cavity of the earphone, when the user does not wear the earphone, the air pressure sensor can detect that an atmospheric pressure value is a, when the user wears the earphone, the air pressure sensor can detect that an ear pressure value in the ear canal is b, and since the user wears the earphone, a is a certain sealed state between the earphone and the ear, so b > a, so that a can be used as a detection threshold for determining whether the earphone is worn, and when the air pressure sensor respectively arranged in the front cavity of the left earphone or the right earphone detects that the air pressure value in the corresponding ear canal is greater than the atmospheric pressure value a, it indicates that the earphone is currently worn, and the earphone is controlled to be turned on. If the pressure is not greater than the atmospheric pressure value a, the earphone is kept to be powered off.
In a specific embodiment, with reference to fig. 2, a schematic diagram of a partial circuit structure in the above-mentioned headset is shown. The earphone at least comprises a memory, a power module, a main control chip and a power amplifier module, wherein the left earphone head (namely a left earphone) and the right earphone head (namely a right earphone) are arranged in the earphone; the main control chip is integrated with a DSP (Digital Signal Processing) module.
Wherein the memory: the earphone is used for storing the air pressure value and the air pressure mean value acquired by the air pressure sensor and the gains of the left earphone and the right earphone;
a main control chip: the earphone comprises a DSP module and is responsible for realizing the method to complete the function control of the whole earphone;
a DSP module: calling related data in the memory, calculating and processing, and sending a result instruction to the power amplifier module;
a power amplifier module: executing the instruction on the left earphone and the right earphone according to the instruction given by the DSP module;
a power supply module: the power amplifier is used for providing power for the memory, the main control chip and the power amplifier module.
Specifically, after the air pressure value in the auditory canal is acquired by the air pressure sensor, the air pressure value is immediately transmitted to the DSP module, the DSP module judges that the air pressure value in the auditory canal is larger than the atmospheric pressure a through a preset algorithm, namely the wearing state of the user is obtained, the DSP module sends a starting-up instruction, the main control chip starts up to work, and the earphone is started up. If the air pressure value in the auditory canal is judged to be not more than the atmospheric pressure a, the earphone is kept in the power-off state.
In an embodiment, the step S1 of playing a single frequency signal through the left earphone and the right earphone includes:
step S201, respectively playing a single-frequency signal with a set duration and a gradually increased voltage value through the left earphone and the right earphone;
step S2 of respectively obtaining the air pressure value in the corresponding ear canal when the left earphone and the right earphone are played or the voltage value of the single-frequency signal played in the corresponding earphone when the playing stopping instruction is received includes:
step S202, when the left earphone and the right earphone receive a playing stopping instruction sent by a user, acquiring voltage values of corresponding single-frequency signals, wherein the voltage values are a first voltage value and a second voltage value respectively;
the step S3 of calculating the loudness gain difference between the left earphone and the right earphone according to the air pressure value or the voltage value includes:
step S203, comparing the voltage difference value of the first voltage value and the second voltage value;
and step S204, calculating the loudness gain difference value of the left earphone and the right earphone according to the voltage difference value.
In this embodiment, the above method applies loudness gain adjustment for users with hearing impairments. The sensitivity of the left and right ears of a user with hearing impairment is different. Therefore, a single-frequency signal (for example, a single-frequency signal with a duration of 1000Hz and a duration of 0.5 second) with a set duration and a gradually increasing voltage value is played through the left earphone until the left ear of the user just hears the sound, at this time, the user can make a feedback instruction to stop playing the single-frequency signal, and when the instruction to stop playing the single-frequency signal is received, the first voltage value of the single-frequency signal currently played in the left earphone is obtained as V1;
the single-frequency signal with set duration and gradually increased voltage value is played through the right earphone (taking 1000Hz, 0.5 second duration single-frequency signal as an example), until the right ear of the user just hears the sound, the user can make a feedback instruction to stop playing the single-frequency signal at this time, and when the instruction of stopping playing the single-frequency signal is received, the second voltage value of the single-frequency signal played in the current right earphone is obtained to be V2.
Further, comparing the difference between the first voltage value and the second voltage value, if V1-V2= d, the right earphone is d lower than the left earphone in the total gain configuration of the left earphone and the right earphone, otherwise, the same process is not repeated.
In this embodiment, the above-mentioned scheme of adjusting the loudness of the left earphone and the right earphone by obtaining the air pressure value to calculate the loudness gain difference between the left earphone and the right earphone is a scheme of automatically adjusting the loudness gain; the above-mentioned voltage value of the single-frequency signal that obtains playing in the corresponding earphone when receiving and stopping playing the order, and then carry out the calculation of the loudness gain difference of left earphone and right earphone, thus the scheme of adjusting the loudness of left earphone and right earphone is the scheme that a user initiatively adjusted the loudness gain. It can be understood that the above-mentioned automatic adjustment and active adjustment modes can be performed alternately, that is, the active adjustment can be performed first, and then the automatic adjustment can be performed; or the automatic adjustment is carried out firstly and then the active adjustment is carried out. The combination of the two adjusting modes is adopted, so that the accuracy in adjusting is improved, and the flexibility is higher.

In one embodiment, the left earphone and the right earphone are provided with touch areas; after the step S4 of adjusting the loudness of the left headphone and the right headphone according to the loudness gain difference of the left headphone and the right headphone, the method includes:
step S5, when a touch signal that the user touches the left earphone or the right earphone is received, gradually increasing the loudness gain of the corresponding left earphone or the right earphone until a touch signal that the user touches the corresponding left earphone or the right earphone is received again.
In this embodiment, when the user wears the headphones, if the loudness of the left headphone and the loudness of the right headphone are inconsistent, the user needs to perform the optimal adjustment again. For example, if the user feels that the loudness of the left headphone is lower than that of the right headphone, the user may touch the touch area of the left headphone to trigger the touch signal, and then gradually increase the loudness gain of the left headphone.
