Abstract

The system consists of the sound box, the digital audio frequency processor, the audio frequency amplifier, the sound source, also including the storage medium and the reader of the storage medium as the characters of the system. The characteristic parameters and the desired characteristics are described in the digital form and stored in the storage medium. The storage medium is put in the reader, which is positioned in the digital audio frequency processor. Based on the characteristic parameters and the desired characteristics stored and described in the storage, the digital audio frequency processor modifies the frequency signal sent from the sound source, and through the audio frequency amplifier drives the sound box, in order to get the desired output of the sound.

Description

Sound system capable of describing and modifying parameters of loudspeaker
Affiliated technical field
The present invention relates to a kind of system, particularly a kind of sound system capable of describing and modifying parameters of loudspeaker.
Background technology
As everyone knows, the distortion that loudspeaker, audio amplifier cause is distortion maximum in each monomer equipment of sound system, thereby the impact of counterweight playback matter also is maximum. In existing sound system, what people pursued is the minimum distortion of each monomer equipment, seldom each monomer equipment is connected consideration. Especially aspect audio amplifier, often the audio amplifier of the electronic circuit part of prime and back is partly isolated and come arbitrarily combination pairing. But actual conditions are owing to the impact of a variety of causes, and each monomer audio amplifier is not just the same, and they always vary on the sound equipment performance. Thereby the electronic circuit of prime part should process accordingly according to the actual performance parameter of dubbing case, only in this way just can make distortion reduce to minimum.
Summary of the invention
The object of the present invention is to provide a kind of sound system capable of describing and modifying parameters of loudspeaker. Utilize electronic circuit according to characterisitic parameter and the desired characteristic of audio amplifier the parameter of whole system to be revised, to reach the purpose that improves tonequality.
Purpose of the present invention can reach by following measures: a kind of sound system capable of describing and modifying parameters of loudspeaker, comprise audio amplifier, digital audio processor, audio-frequency amplifier, source of sound, it is characterized in that: also have storage medium, storage medium reader, the characteristic parameter of audio amplifier and desired characteristic are described in digital form and are stored in the storage medium, be provided with the storage medium reader in the digital audio processor, storage medium is put into the storage medium reader, by characterisitic parameter and the desired characteristic of digital audio processor according to storage medium stores and description audio amplifier, the audio signal that source of sound is sent here is revised relatively, and by audio-frequency amplifier driving audio amplifier, make it obtain the sound output of expectation.
Purpose of the present invention can reach by following measures: storage medium adopts IC-card. The storage medium reader adopts the IC-card reader. Data in the storage medium are divided into audio amplifier self-characteristic parameter region, manufacturer recommends desired characteristic parameter region and user to define desired characteristic parameter region Three regions.
The present invention has following advantage compared to existing technology: line design is reasonable, audio amplifier actual performance parameter is described in digital form and is stored in the storage medium, put into again the electronic circuit part (digital audio processor) of prime, make the prime electronic circuit partly know characterisitic parameter and the desired characteristic of rear class audio amplifier, and can revise the parameter (such as amplitude-frequency, phase frequency or other parameter) of whole system, thereby can improve tonequality, obtain the sound output of expectation.
Description of drawings
Fig. 1 is functional-block diagram of the present invention.
The specific embodiment
The present invention does a step below in conjunction with accompanying drawing (embodiment) and describes in detail:
With reference to Fig. 1, the present invention includes audio amplifier 1, storage medium 2, digital audio processor 3, audio-frequency amplifier 4, source of sound 5, storage medium reader 6 etc. Storage medium 2 can adopt the IC card; Storage medium reader 6 can adopt the IC-card reader. The designer of audio amplifier carries out digitized description with the characterisitic parameter of audio amplifier and desired characteristic and is stored in the storage medium 2 (such as IC-card), be provided with storage medium reader 6 (such as the IC-card reader) in the digital audio processor 3, storage medium 2 is put into storage medium reader 6, read by it, and via characterisitic parameter and the desired characteristic of electronic circuit (such as the digital audio processor of doing with DSP) according to audio amplifier, the audio signal that source of sound 5 is sent here is carried out relative parameter (such as amplitude-frequency, phase frequency or other correction), drive audio amplifier 1 by audio-frequency amplifier 4 again, make it obtain the sound output of expectation.
The characterisitic parameter of the audio amplifier in the system of the present invention and desired characteristic are that the data format with a kind of SBPT of being called as (Sound Box Parameter Table) transmits and stores. The principle that project category is variable, data length is adjustable is adopted in the establishment of whole data format, now is described as follows as an example of the three frequency division audio amplifier example:
