Specific embodiment
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.
The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
The present embodiment is related to a kind of vehicle audio automatic adjustment system, and as shown in Figure 1, which mainly includes master controller
1, storage unit 2, audio acquisition device 3, computing unit 4.
Wherein, key control unit of the master controller 1 as whole system, can be using the member with control function
Part, such as vehicle ECU can be used in the present embodiment using single-chip microcontroller device having data processing function.
Storage unit 2 is connected with master controller 1, for storing based on the optimal audio feature under cabin space；This implementation
In example, optimal audio feature can be vehicle when leaving the factory, and vehicle factor is according to the sound of multimedia host, power amplifier or loudspeaker
The factors such as frequency performance and vehicle inner space (material in such as interior volume, compartment), to the audio effect of vehicle
It is debugged, and, with the parameter of best audio effect, optimal audio feature will be set as after debugging.In the present embodiment, most
Excellent audio feature is audio frequency response curve.
Audio acquisition device 3 is connected with the master controller 1, for obtaining the practical audio feature under cabin space；Base
It is audio frequency response curve in optimal audio feature-set, which is similarly audio frequency response curve.In addition, in this reality
It applies in example, the audio acquisition device 3 is microphone, in order to better improve overall effect, and ANC also can be used (actively
Noise reduction) microphone.Effect is obtained in order to further improve practical audio feature, and in the present embodiment, audio acquisition device 3 is point
It is disposed adjacent in four of four corner points of the interior.
Computing unit 4 is connected with the master controller 1, between the practical audio feature of analytical calculation and optimal audio feature
Difference；It is all made of audio frequency response curve based on practical audio feature as above and optimal audio feature, is analyzed and is obtained by computing unit 4
Difference, be similarly based on the audio frequency response curve formed under different frequency.
In addition, in order to realize the controllability to whole system, in the present embodiment, it is additionally provided with and is connect with master controller 1
Switch unit 5, by control switch unit 5, to control whether computing unit 4 triggers work, so that master controller 1 is according to described
Difference compensates the practical audio feature, to obtain the target audio feature close to the optimal audio feature.
Based on vehicle audio automatic adjustment system as above, vehicle audio automatic adjusting method of the present invention is main to wrap
Include following steps:
It obtains and prestores based on the optimal audio feature under cabin space；
It obtains based on practical audio feature under cabin space, identical with the optimal audio characteristic properties；
Analyze the difference between the practical audio feature and the optimal audio feature；
According to the difference, the practical audio feature is compensated, to obtain close to the optimal audio feature
Target audio feature.
Based on the Integral Thought of method as above, specifically, in the present embodiment, this method mainly includes the following steps:
By control switch unit 5, vehicle audio automatic adjustment system is activated, to obtain target audio feature；
By audio acquisition device 3, obtain based on reality under cabin space, identical with the optimal audio characteristic properties
Border audio feature；It is so-called identical as the optimal audio characteristic properties in the present embodiment, refer to the sound ginseng under same frequency
Number；
It is digital signal to optimal audio feature and practical audio Feature Conversion, to form optimal audio as shown in Figure 2
Curve M (in Fig. 2 shown in heavy line), practical audio curve N (in Fig. 2 shown in fine line).Based on each frequency of optimal audio curve M
The numerical value of practical audio curve N, calculates the difference value under each frequency by computing unit 4 corresponding to numerical value under rate.Example
Such as, in Fig. 2, optimal audio curve M is formed by corresponding performance number under multiple and different frequencies is coherent；Practical audio curve N by
The coherent composition of corresponding actual power value under multiple and different frequencies.As can be seen from Figure, under equal-wattage, optimal audio curve
The performance number in performance number and practical audio curve N in M differs.By taking the corresponding each curve of a, b, c, n frequency values as an example, most
Performance number of the excellent audio curve M under a, b, c, n frequency values is respectively A1, B1, C1, N1, meanwhile, according to frequency values, look for reality
Numerical value A2, B2, C2, the N2 of border audio curve N under corresponding frequencies value have differences between the two values to correspond to each other, because
This compensates the practical audio feature by master controller 1 after 4 calculating of the computing unit difference, generates offset
A3, B3, C3, N3 after multiple compensation value calculations obtain, generate compensation audio curve Q, as a result, in this way, finally being pasted
The target audio feature of the nearly optimal audio feature.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
