When casting to user, intensity of sound decaying is smaller, and the intensity of sound adjusting parameter value being calculated is smaller.
S402, according between the distance between sound source device and user and sound source device and voice signal central point away from
From ratio square, obtain intensity of sound adjusting parameter.
Specifically, by above-mentioned calculation, calculating the end value got as described in step S401 namely sound being strong
Spend adjusting parameter.
Optionally, using above-mentioned calculation, corresponding intensity of sound adjustment can be sought to each sound source device
Parameter, for different sound source devices, the intensity of sound adjusting parameter being calculated is different, sets apart from the farther away sound source of user
It is standby, it is relatively large to calculate the intensity of sound adjusting parameter obtained, and apart from the closer sound source device of user, calculate acquisition
Intensity of sound adjusting parameter is relatively small.
Further, according between the distance between sound source device and user and sound source device and voice signal central point
Distance ratio square, obtain intensity of sound adjusting parameter, comprising:
When the distance between sound source device and user, with the distance between sound source device and voice signal central point ratio
When square being greater than 1, determine that intensity of sound adjusting parameter is that the intensity of voice signal is increased to the corresponding adjusted value of ratio.
Optionally, when the intensity of sound adjusting parameter H that above-mentioned calculating obtains is greater than 1, between sound source device and user
Distance is greater than the distance between sound source device and voice signal central point, at this time the voice signal to be played of the sound source device
Intensity will enhance according to the strength of sound source adjusting parameter.
Alternatively, when the distance between sound source device and user and the distance between sound source device and voice signal central point
Ratio square less than 1 when, determine that intensity of sound adjusting parameter is that the intensity of voice signal is reduced to the corresponding adjusted value of ratio.

When, the distance between sound source device and user are less than the distance between sound source device and voice signal central point, at this time the sound
The intensity of the voice signal to be played of source device will weaken according to the strength of sound source adjusting parameter.
When being received by the voice signal of above sound intensity each sound source device adjusted by user, regardless of user
Any position in automobile, it is considered that the user is the center in automobile, to realize 3D solid
Sound effective value, efficiently solve user and each sound source device decay apart from different caused sound source device signal it is inconsistent
Problem improves the audio experience of user.
Optionally, sound source device can be the equipment that loudspeaker, loudspeaker etc. can play voice signal in the application, specifically
With no restrictions.
Further, it when there is multiple users in automobile, can be determined to wrap first according to the location information of multiple users
Minimum circumscribed circle containing multiple user is calculated using the center of circle of the minimum circumscribed circle as the location information of multiple users,
So that the passenger being located in the circumscribed circle region has higher audio experience.
Intensity of sound method of adjustment provided by the embodiments of the present application, by obtaining the location information of sound source device, user
The location information of location information and voice signal central point, and according to the location information of the sound source device got, the position of user
The location information and preset rules of confidence breath and voice signal central point, calculate and obtain intensity of sound adjusting parameter, utilize the sound
