In some embodiments, a method of obtaining performance parameters of a headset includes: when the connection between the electronic equipment and the earphone is detected, the model of the earphone is obtained; acquiring performance parameters of the earphone from a second mapping table based on the model of the earphone; the second mapping table comprises at least one mapping relation between the earphone model number and the performance parameter. Here, the earphone model is used as the identification information of the earphone, and the performance parameter corresponding to the earphone is determined according to the earphone model.
Detecting that the electronic device establishes connection with the headset, and obtaining the headset model includes, but is not limited to, the following two cases:
first, a connection with the headset is detected for the first time.
When the connection with the earphone is detected for the first time, the determination of the earphone model is automatically detected by the electronic equipment or is determined according to the input information of the user. But when the earphone type selection interface is determined according to the input information of the user, controlling to display an earphone type selection interface, wherein a plurality of earphone type options are displayed on the earphone type selection interface. The display form of the plurality of earphone model options on the earphone model selection interface may be a list form, an icon form or the like. When a selection operation of any earphone model option is detected, the selected earphone model is taken as the model of the earphone. Alternatively, the headset model is entered directly by the user.
And secondly, the connection with the earphone is not detected for the first time, and the earphone model determined when the earphone is connected last time can be directly obtained.
In some embodiments, the determining the maximum output power of the headset based on the performance parameter of the headset comprises: determining a first output power based on the earphone type; determining a power coefficient based on a sensitivity of the headset; determining a second output power based on the power rating of the earphone and the power coefficient; and taking the minimum value of the first output power and the second output power as the maximum output power of the earphone.
In practice, in order to ensure the hearing and hearing of the user, the output power range of the earphone should be smaller than the maximum output power. Here, a generally applicable output power range may be determined based on the type of earphone, and the output power range more matched to the earphone may be determined based further on the sensitivity and rated power of the earphone.
In other embodiments, the determining the maximum output power of the earphone based on the performance parameter of the earphone includes: determining a power coefficient based on a sensitivity of the headset; determining a second output power based on the power rating of the earphone and the power coefficient; and taking the second output power as the maximum output power of the earphone.
Since the output power range determined by the sensitivity and rated power of the earphone is more matched with the earphone, the maximum output power can be determined directly by using the sensitivity and rated power.
In other embodiments, the determining the maximum output power of the earphone based on the performance parameter of the earphone includes: determining a first output power based on the earphone type; and taking the first output power as the maximum output power of the earphone.
Determining a first output power based on the headset type, comprising: determining a first output power from a third mapping table based on the earphone type; the third mapping table includes a mapping relationship between at least one earphone type and the first output power. Or determining a maximum output voltage from a fourth mapping table based on the earphone type; the fourth mapping table comprises at least one mapping relation between earphone type and maximum output voltage; and calculating to obtain first output power based on the maximum output voltage and the impedance of the earphone.
In some embodiments, the method further comprises, prior to step 103: respectively controlling the output of the at least one single-frequency signal based on at least two volume control parameters; acquiring a user selection instruction acquired by an input unit, and determining respective corresponding volume control parameters of the at least one single-frequency signal based on the user selection instruction; and establishing the first mapping table by utilizing the volume control parameters corresponding to the at least one single-frequency signal.
Illustratively, at least two volume control parameters of a single frequency signal are determined based on the maximum output power of the earphone, such that the output power of the earphone when outputting the single frequency signal does not exceed the maximum output power. That is, the volume control parameter determined in advance for each single frequency signal does not cause the output power of the earphone to exceed the preset range.
Here, the sound effect control parameter may be an output voltage of the single frequency signal. Aiming at the hearing experience of a user on different single-frequency signals, when playing single-frequency signals with different output voltages by utilizing one earphone, for example, 300Hz/30mv,300Hz/40mv and 300Hz/60mv are played, the user can select the best output voltage which is most suitable for the 300Hz signals at the UI interface, so that calibration with different frequencies, such as 400Hz,800Hz,1KHz,2KHz and the like, is performed. Therefore, the preferences of the user using a certain earphone in each frequency band are collected and stored in the software calibration file, when the user listens to the audio and the like by using the earphone again next time, the optimal output voltage of each frequency is adjusted according to the previous calibration file by analyzing the frequency components contained in the audio, and the listening feeling of the user is improved.
In practical application, the first mapping table includes volume control parameters corresponding to the at least one single-frequency signal in different environmental spaces; wherein different ambient spaces correspond to different ambient noise levels.
Further, the method further comprises: acquiring a volume adjustment instruction in the at least one environment space; adjusting a volume control parameter of at least part of the single-frequency signals in the first mapping table based on the volume adjustment instruction; and storing the adjusted first mapping table.
That is, in determining the volume control parameter of the single frequency signal, both the listening habit of the user and the playing environment are considered. Thus, the optimal volume control parameters suitable for different playing environments are provided for the user.
Here, since the noise level of the playing environment also affects the hearing of the user, different volume control parameters may be set according to different noise levels, for example, the noise levels may be divided into a first level of 10db to 30db, a second level of 30db to 50db, a third level of 50db to 70db, a fourth level of 70db to 90db, and a fifth level of 90db or more. When the environmental noise level is detected to be larger, the corresponding volume control parameter is also larger, when the noise level is too large (such as a fifth level), the corresponding volume control parameter may enable the output power to exceed the maximum output power, at this time, the audio file is controlled to stop outputting until the environmental noise is reduced to the fourth level or below, and then the audio file is controlled to continue outputting, so that the hearing of a user is prevented from being damaged.
Here, when the target audio file is controlled to be output based on the target volume control parameters, the volume control parameters of different single-frequency signals are the same or different, and the output effect after the single-frequency signals are fused is considered in advance, so that the volume control parameters set for the different single-frequency signals in advance cannot have great influence on the overall output sound effect of the target audio file.
By adopting the technical scheme, when the connection between the electronic equipment and the earphone is detected, a reasonable output power range can be set for different earphone performances, meanwhile, a first mapping table is established according to the hearing feeling of a user on different frequency band sounds, the first mapping table is pre-stored with the optimal volume control parameters of different single frequency signals, when the output of an audio file is controlled, the target volume control parameters corresponding to the different single frequency signals in the audio file are determined from the first mapping table, the output of the audio file is controlled according to the determined target volume control parameters, namely, the optimal volume output can be matched for the signals of each frequency band, the hearing feeling of the user is improved, the output power of the earphone is ensured not to exceed the maximum output power, and the harm to the ear hearing of the user is avoided.

The sensitivity of the earphone is the sound pressure level which can be emitted by the earphone when the earphone inputs 1 milliwatt of power, so that the higher the sensitivity is, the smaller the impedance is, the easier the earphone is to sound and the easier the earphone is to drive, the lower the second output power of the earphone is, and the lower the sensitivity is, the higher the second output power of the earphone is. For example, the earphone model is half in ear type of MH135, the sensitivity is 105+ -3 db, the sensitivity coefficient is 0.6, and the second output power is 0.6mw obtained by multiplying the rated power by the sensitivity coefficient; the earphone model is MH130 in the ear, the sensitivity is 100+ -2 db, the sensitivity coefficient is 0.8, and the second output power is 3.2mw.
