Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
It is the flow chart of the sound quality adjusting method of earphone provided in an embodiment of the present invention referring to Fig. 1, Fig. 1, is applied to terminal,
The terminal is connected with earphone, and the earphone includes auricular concha.As shown in Figure 1, comprising the following steps:
Whether step 101, the detection earphone are inserted into wearer's ear canal.
In this step, it can detect the real-time range between auricular concha and wearer's ear canal eardrum.If detecting described
Real-time range between auricular concha and wearer's ear canal eardrum is less than or equal to pre-determined distance threshold value, then obtain it is described in real time away from
From state duration.If the state duration is greater than or equal to preset time threshold, it is determined that detect the ear
Machine is inserted into wearer's ear canal.Wherein, the state duration be detect the real-time range be less than or equal to it is default away from
Duration from threshold value.Wherein, the pre-determined distance threshold value and preset time threshold can be preset.
Step 102, when detecting that earphone is inserted into wearer's ear canal, detect auricular concha and wearer's ear canal eardrum it
Between distance.
In embodiments of the present invention, distance measuring sensor can be set on auricular concha.When detecting that earphone is worn into wearer
When ear canal, the distance between auricular concha and wearer's ear canal eardrum are detected using the distance measuring sensor.
Step 103 determines the corresponding acoustic pressure adjusted value of the distance between the auricular concha and wearer's ear canal eardrum.
Specifically, in this step, according to preset first corresponding relationship, determining the auricular concha and wearer's ear canal
The corresponding first ear canal coupler length value of the distance between eardrum determines described first according to preset second corresponding relationship
The corresponding acoustic pressure adjusted value of ear canal coupler length value.Wherein, first corresponding relationship is auricular concha and wearer's ear canal periosteum
The distance between the corresponding relationship of cavity length is coupled with ear canal, second corresponding relationship is ear canal coupler length value and acoustic pressure

1um。
Step 204 determines the corresponding acoustic pressure adjusted value of the distance between the auricular concha and wearer's ear canal eardrum.
The distance detected according to step 203, the first corresponding relationship being arranged in finding step 201, determines this apart from right
The the first ear canal coupler length value answered.Then, second be arranged in the first ear canal coupler length value finding step 201 is utilized
Corresponding acoustic pressure adjusted value can be obtained in corresponding relationship.
By taking the corresponding relationship is the corresponding relationship of multiple ear canal coupler length range values and acoustic pressure adjusting range value as an example.
According to the distance that detected, determine that this, apart from corresponding ear canal coupler length range, is determined further according to the corresponding relationship
Corresponding acoustic pressure adjusting range.
Step 205, according to the acoustic pressure adjusted value, adjust the acoustic pressure of the audio signal of the earphone output.
By the above-mentioned means, can ensure that according to the coupling cavity length detected, the acoustic pressure of the high band exported from earphone
Curve is still that design is consistent, so that the earphone acoustical quality that consumer hears is always consistent.
In this way, in the embodiment of the present invention, when detecting that earphone is inserted into wearer's ear canal, according to the auricular concha detected and
The distance between wearer's ear canal eardrum determines corresponding acoustic pressure adjusted value, and defeated using the acoustic pressure adjusted value adjustment earphone
