First, wired analog interface 105 is inserted in audio frequency apparatus, now, user is according to the noise situation of external environment condition, according to oneself user demand manually tuning device 104 adjust the volume of loud speaker 240, first sound sound sensor 220 gather earphone ambient noise signal and by ambient noise Signal transmissions to the receiver module 211 of microcontroller 210, rising tone sound sensor 230 gather loud speaker 240 voice signal and by transmission of sound signals to the receiver module 211 of microcontroller 210.
In tuning module 212, multiple range of sound is set, the range of sound is carried out separation by sound threshold value and is set, when automatic tone tuning device 200 works, tuning module 212 pairs of noise volumes are carried out range of sound coupling and from multiple range of sound, are selected the coupling range of sound, and the coupling range of sound has high pitch threshold value and bass threshold value; Namely high pitch threshold value and bass threshold value are the volume values at the two ends up and down in the range of sound, specifically, each range of sound all has high pitch threshold value and bass threshold value, high pitch threshold value and bass threshold value are comparatively speaking, such as: namely same sound threshold value is the bass threshold value in the range of sound larger in adjacent two ranges of sound, also be the high pitch threshold value in the less range of sound, tuning module 212 pairs of noise volumes carry out range of sound coupling, that is to say and judge which rank of range of sound is noise volume be in simultaneously.
When external environment changes, the volume of extraneous noise signal can change, the change of the record ambient noise volume that first sound sound sensor 220 is real-time, and draw the volume average of ambient noise signal in the first acquisition time section, first acquisition time section is the time of artificial setting, in the present embodiment, the first acquisition time section is set smaller than 5min.It should be noted that, the time of the first acquisition time section can be arranged according to user's request, and in the present embodiment, the first acquisition time section is set as 5s.
When the volume average of ambient noise signal in the first acquisition time section exceedes the high pitch threshold value in the coupling range of sound, volume heightened by tuning module 212 control loudspeaker 240, when the volume average of noise volume in the first acquisition time section is lower than the bass threshold value in the coupling range of sound, volume turned down by tuning module 212 control loudspeaker 240.When the extraneous average of noise volume within the first acquisition time section time exceedes the high pitch threshold value in this range of sound, illustrate that the external environment condition residing for user is comparatively noisy, now, tuning module 212 control loudspeaker 240 improves volume, to avoid extraneous noise signal to produce interference to pleasant signal, affect audio experience.And when the volume average of extraneous noise signal in the first acquisition time section is lower than bass threshold value; illustrate that the environment residing for user is comparatively quiet; now the pleasant volume of loud speaker 240 just can be larger more clear; and the ear of people is for a long time under large volume environment; easily sustain damage, therefore, turn down volume by tuning module 212 control loudspeaker 240; the audio experience of people can not be affected, but the effect of protection ear can be played.
Multiple range of sound has most high sound threshold value, warning sound threshold value and minimum sound threshold value, most high sound threshold value and minimum sound threshold value are the healthy tolerance range settings of ear according to people, in the present embodiment, most high sound threshold value is 120dB, when loud speaker 240 volume is higher than 120dB, tuning module 212 output mute order in microcontroller 210 is to audio frequency tuning module 213, and the automatic control loudspeaker 240 of audio frequency tuning module 213 is quiet, prevents the ear of people from suffering damage.
In the process that controller control loudspeaker 240 is quiet, if user still wants to open loud speaker 240, the manual tuning device 104 of direct control.More preferably, the earphone that the present embodiment provides adjusts in the method for volume automatically, also comprise step: when manual tuning device 104 adjust the volume of loud speaker 240 or automatic tone tuning device 200 regulate loud speaker 240 volume time, when in the second acquisition time section, the broadcast sound volume that rising tone sound sensor 230 gathers is greater than warning sound threshold value, and microcontroller 210 control loudspeaker 240 turns down volume extremely lower than warning sound threshold value.Namely the volume that manual tuning device 104 adjusts loud speaker 240 is greater than the warning sound threshold value time more than after the second acquisition time section, microcontroller 210 control loudspeaker 240 reduces volume extremely lower than warning sound threshold value, the second acquisition time section is herein the time of artificial setting, second acquisition time section is less than 90min and is advisable, because people uses earphone for a long time under large volume environment, very easily cause damage to ear, in the present embodiment, the second acquisition time section is set to 90min.In the present embodiment, warning sound threshold value is 85dB, and warning sound threshold value is less than maximum acoustic threshold value.
In addition, because user is after using earphone at every turn, usually its volume can not be adjusted, the volume of loud speaker 240 is exported and maintains the state at the end of using last time, if last time is when using, when the volume of loud speaker 240 exports and is greater than most high sound threshold value, open earphone next time again to use, the sense of discomfort of ear is probably caused because volume is excessive, therefore, in the present embodiment, when wired analog interface 105 inserts audio frequency apparatus, receiver module 211 in microcontroller 210 starts to receive the broadcast sound volume signal that rising tone sound sensor 230 transmits, receiver module 211 by this broadcast sound volume signal transmission to tuning module 212, when broadcast sound volume is greater than most high sound threshold value 120dB, tuning module 212 pairs of audio frequency tuning modules 213 export the Output rusults turning down volume, audio frequency tuning module 213 control loudspeaker 240 adjusts volume to most between high sound threshold value and minimum sound threshold value.
It is further preferred that when wired analog interface 105 inserts audio frequency apparatus, no matter whether broadcast sound volume exceeds most high sound threshold value, and microcontroller 210 all control loudspeaker 240 adjusts the volume range that volume listens to people preferably, as 50dB ~ 70dB.
Specifically, in the present embodiment, when controller control loudspeaker 240 increases or reduces volume, be adopt the mode that index increases or index reduces to realize.Index increases or index reduction refers to: the change of loud speaker 240 volume and the change exponentially relation of ambient noise signal average, that is to say that, if with loud speaker 240 volume for y, the average of ambient noise signal is x, then y=ae
x(wherein a is coefficient, in the present embodiment, and 0<a<10).
The advantage of the volume adjusting mode that index increases and index reduces is: larger in the average of extraneous noise signal, when that is to say that x is larger, the adjustment amount of loud speaker 240 volume y is larger, and less in the average of extraneous noise signal, when that is to say that x is less, the adjustment amount of loud speaker 240 volume y is very little.Under lower noise environment, the audio experience impact of change on people of ambient noise signal is little, and under high noise environments, the sense of hearing impact of change on people of ambient noise signal is larger, after arranging like this, more meets the experience of people.
Embodiment described above is the present invention's part embodiment, instead of whole embodiments.The detailed description of embodiments of the invention the claimed scope of the present invention of not intended to be limiting, but only represent selected embodiment of the present invention.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
