The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
The technical idea of the application is as follows:
under the normal condition, the higher earphone of tone quality, like in-ear earphone etc. need form the structure sealed relatively with the duct to prevent that sound from leaking, and the separation external noise, in order to guarantee tone quality and conversation effect. In different wearing states, the sealing degree between the earphone and the ear canal of the human ear is different, so that the earphone is influenced to play the best tone quality.
This application utilizes the principle that the sealed degree receives the wearing state influence between earphone and the people's ear canal, utilizes the speaker diaphragm to vibrate the resistance that receives different under different sealed conditions, leads to impedance parameter to have the law that changes, realizes the detection to the improper wearing state of earphone to detect the earphone and wear when improper to tone quality compensation adjustment.
Specifically, fig. 1 is a schematic flowchart of a sound quality adjusting method according to an embodiment of the present application, and as shown in fig. 1, a sound quality adjusting method includes:
step S110, collecting electric signals at two ends of a loudspeaker of the earphone, and determining impedance parameters of the earphone in the wearing state according to the electric signals.
The electric signals at the two ends of the earphone loudspeaker, namely the signals of voltage, current and the like flowing into the loudspeaker and flowing out of the loudspeaker, can obtain the vibration condition of the loudspeaker diaphragm through the data so as to obtain the impedance parameter of the loudspeaker in the wearing state. By comparing the impedance parameter with a preset impedance parameter threshold value of the earphone loudspeaker, the wearing state of the earphone can be known, whether the wearing tightness of the earphone is good or not is determined, and whether sound compensation adjustment is needed or not is determined. The electric signal acquisition process and the impedance parameter determination process can be continuously carried out in the use process of the earphone so as to adapt to the wearing state change of the earphone caused by the movement of a user in real time.
And step S120, when the impedance parameter is greater than the first threshold value and less than the second threshold value, performing compensation adjustment on the medium and low frequency tone quality of the earphone according to the impedance parameter and a pre-stored compensation curve.
In this embodiment, the first threshold value is an impedance parameter of the speaker when the earphone is worn to form a preset closed space, and the impedance parameter can be preset by collecting a large amount of user data and can also be adjusted and set by the user. The second threshold is an impedance parameter of the speaker when the earphone is in an open state, and the value may be an impedance parameter measured when the earphone is completely open (i.e., not worn), or an impedance parameter measured when the earphone is worn loosely. When the impedance parameter is larger than the first threshold and smaller than the second threshold, it is indicated that the earphone is not worn properly, sound leakage exists, the middle and low frequency tone quality needs to be compensated and adjusted, and then the middle and low frequency tone quality of the earphone is compensated and adjusted according to the impedance parameter and the pre-stored compensation curve.
Therefore, the impedance parameters of the loudspeaker are obtained by detecting the electric signals at the two ends of the loudspeaker of the earphone, and are compared with the impedance parameters of the earphone in a sealed wearing state and an open state respectively to know the wearing state of the earphone.
In one embodiment of the present application, the method further comprises: when the impedance parameter is less than or equal to the first threshold value, closing the compensation adjustment function; and/or when the impedance parameter changes from being less than the second threshold value to being greater than or equal to the second threshold value, closing the compensation adjustment function, and sending out a warning signal to remind the wearer of re-wearing the earphone.
When the impedance parameter is less than or equal to the first threshold, the wearing state of the earphone is very accurate, and a good sealing cavity sealing effect is formed between the earphone and the auditory canal, so that better tone quality can be obtained without adjustment, and the compensation adjustment function can be closed.
When the impedance parameter is changed from being smaller than the second threshold value to being larger than or equal to the second threshold value, the wearing mode of the earphone is changed to be seriously improper, and the tone quality influence caused by improper sealing at the moment can not be realized even if the impedance parameter is compensated, so that the compensation adjusting function is closed at the moment, and a warning signal is sent to remind a wearer of wearing the earphone again to obtain good tone quality experience. Wherein the second threshold may be a speaker impedance parameter measured when the headset is fully open. By determining that the alarm prompt criterion is 'the impedance parameter is changed from being smaller than the second threshold value to being larger than or equal to the second threshold value', the problem that the earphone alarms from the beginning of power-on can be avoided. In addition, in one embodiment of the application, an alarm termination function can be further set, so that the alarm prompt is turned off when the earphone is taken off and is not used for the moment.
In one embodiment of the present application, the compensation curve is a series of equalizer curves comprising a plurality of equalizer curves corresponding to different impedance parameters.
In step S120, performing compensation adjustment on the low-and-medium-frequency tone quality of the earphone according to the impedance parameter and a pre-stored compensation curve, including: and selecting a corresponding equalizer curve according to the impedance parameter, and compensating and adjusting the sound output by the earphone loudspeaker by using the selected equalizer curve.
Fig. 2 shows a schematic diagram of impedance curves of the earphone in different wearing states, and it can be seen from fig. 2 that when the earphone is not worn, the low-frequency impedance is high, which seriously affects the quality of the medium and low-frequency sound, and the low-frequency impedance peak B thereof can be used as a second threshold. When the earphone is worn completely, the impedance is obviously reduced, the low-frequency tone quality is optimal, and the peak value A of the low-frequency impedance is obviously lower than that of the peak value B. The application determines a personal model which meets the personal requirements of the wearer between the two states, and determines a first threshold value C.
In one embodiment of the present application, the method further comprises: when the earphone is worn correctly, audio with preset duration is played through the earphone, the impedance parameter of the earphone is determined according to electric signals at two ends of the loudspeaker in the playing process, and the impedance parameter is used as a first threshold value of the earphone. Because the structure of each ear is different, the sealing degree of wearing the earphone is different, so the size of the first threshold value can be set through the personal actual operation of the user.
Referring to fig. 3, a schematic flow chart for determining a first threshold value for a first time a consumer wears a headset is shown. When a consumer wears the earphone for the first time, the consumer sequentially controls the earphone to enter a pairing mode (such as Bluetooth), adjust the wearing position of the earphone, enter a power amplifier calibration mode, play a prompt tone, record a calibration value as an impedance threshold (namely a first threshold C) and play a standard sound source by operating a physical key and the like, and the setting of a personal mode is completed.
After that, the process of wearing and using the earphone by the consumer can refer to the flowchart shown in fig. 4, and in fig. 4, the detection of the impedance parameter of the earphone in the above process is realized by a DSP (Digital Signal Processing).
As shown in fig. 4, when the user uses the earphone, if the impedance parameter is between C and B, that is, if the impedance parameter is greater than the first threshold C and smaller than the second threshold B, it indicates that the earphone is not worn properly, a sealed cavity formed by the earphone is leaked, and the low and medium frequency sound quality effect is lower than that of the personal model of the wearer, so compensation needs to be performed.
If the wearing impedance parameter is between A and C, namely smaller than a first threshold value C, the earphone is well worn, the earphone conforms to the personal model of a wearer, and compensation is not needed; if the impedance parameter is changed to be larger than or equal to the second threshold value B, the wearing state of the earphone is extremely poor, the sealing effect formed by the earphone and the auditory canal is completely absent, the earphone is considered to be worn wrongly and belongs to an abnormal state, and the compensation function is closed and meanwhile the alarm of wearing the earphone again is sent out.
In one embodiment of the present application, the headset is an in-ear headset or a closed-head headset. The in-ear earphone or the closed-type headphone needs to form a good seal between the earphone and the ear canal, so that the low-frequency effect is greatly influenced by wearing, and the low-frequency sound quality effect can be obviously improved by applying the embodiment of the application. In addition, for most active noise reduction earphones, the sealing structure is also required to ensure the noise reduction function of the earphones, so that the active noise reduction earphones are also suitable for applying the embodiment of the application.

In one embodiment of the present application, the compensation curve is a series of equalizer curves comprising a plurality of equalizer curves corresponding to different impedance parameters.
