Abstract
The utility model relates to a multichannel audio processing system. The multichannel audio processing system comprises a multichannel processor, a digital power amplifier and a loudspeaker group. After being processed by the multichannel processor and amplified by the digital power amplifier, an audio signal is then connected with the loudspeaker group to be played. The digital power amplifier comprises a front-placed digital power amplifier, a middle-placed digital power amplifier and a rear-placed digital power amplifier, wherein the output power of the rear-placed digital power amplifier is large than the output power of the front-placed digital power amplifier and the output power of the middle-placed digital power amplifier, and a sound of the loudspeaker group which corresponds to the rear-placed digital power amplifier is highlighted. And the layer sense of the sound is improved, the surround effect of the sound is improved, and perfect auditory enjoyment is brought.
Description
Technical field
The utility model belongs to audio frequency play-back technology field, particularly a kind of multichannel audio treatment system.
Background technology
In existing multichannel audio treatment system, audio signal, is played back by set of speakers after amplifying through digital power amplifier through the audio process decoding again.When digital power amplifier amplifies sound, usually adopt the processing mode of each sound channel power output equalization, so just cause the tone color equalization, the defective such as the third dimension of sound is not strong, and the sound result of broadcast is undesirable.
The utility model content
Technical problem to be solved in the utility model is, a kind of multichannel audio treatment system is provided, and can carry out the power output unequal distribution to the digital power amplifier of each sound channel, improves audio.
The utility model is to realize like this, a kind of multichannel audio treatment system is provided, comprise multichannel processor, digital power amplifier and set of speakers, after audio signal is processed through the multichannel processor, amplified by digital power amplifier again, and then be connected to set of speakers and play, digital power amplifier comprises pre-numbers power amplifier, mid-digital power amplifier and rearmounted digital power amplifier, and the power output of rearmounted digital power amplifier is greater than the power output of pre-numbers power amplifier and mid-digital power amplifier.
Further, the multichannel processor is 6.1 sound channel processors, and digital power amplifier is D class digital power amplifier.
Further, D class digital power amplifier comprises preposition D class digital power amplifier, mid-D class digital power amplifier and rearmounted D class digital power amplifier, and preposition D class digital power amplifier, mid-D class digital power amplifier and rearmounted D class digital power amplifier are respectively exported respectively two sound channels.
Further, set of speakers comprise the preposition set of speakers in the left and right sides, left and right sides center loudspeaker group and about rearmounted set of speakers, the output channels of preposition D class digital power amplifier is corresponding with the preposition set of speakers in the left and right sides respectively, the output channels of mid-D class digital power amplifier is corresponding with left and right sides center loudspeaker group respectively, the output channels of rearmounted D class digital power amplifier respectively with about rearmounted set of speakers corresponding.
Further, between digital power amplifier and set of speakers, be provided with speaker protection circuit.
Compared with prior art, in a kind of multichannel audio treatment system of the present utility model, digital power amplifier comprises pre-numbers power amplifier, mid-digital power amplifier and rearmounted digital power amplifier, the power output of rearmounted digital power amplifier is greater than the power output of pre-numbers power amplifier and mid-digital power amplifier, so that the sound of the corresponding set of speakers of rearmounted digital power amplifier is more outstanding, increase the stereovision of sound, improved the surrounding effect of sound.
Description of drawings
Fig. 1 is the functional schematic of the utility model one preferred embodiment.
Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
See also shown in Figure 1, a kind of multichannel audio treatment system for the utility model preferred embodiment, it comprises multichannel processor, digital power amplifier and set of speakers, after audio signal is processed through the multichannel processor, amplified by digital power amplifier again, and then be connected to set of speakers and play.
In the present embodiment, the multichannel processor is 6.1 sound channel processors, and digital power amplifier is D class digital power amplifier.6.1 the sound channel processor comprises six sound channels, D class digital power amplifier comprises preposition D class digital power amplifier, mid-D class digital power amplifier and rearmounted D class digital power amplifier, preposition D class digital power amplifier, mid-D class digital power amplifier and rearmounted D class digital power amplifier are respectively exported respectively two sound channels, add up to six sound channels.And wherein, the power output of rearmounted D class digital power amplifier is greater than the power output of preposition D class digital power amplifier and mid-D class digital power amplifier.
Set of speakers comprise the preposition set of speakers in the left and right sides, left and right sides center loudspeaker group and about rearmounted set of speakers, the output channels of preposition D class digital power amplifier is corresponding with the preposition set of speakers in the left and right sides respectively, the output channels of mid-D class digital power amplifier is corresponding with left and right sides center loudspeaker group respectively, the output channels of rearmounted D class digital power amplifier respectively with about rearmounted set of speakers corresponding.
After audio signal is processed through 6.1 sound channel processors, be delivered to simultaneously on preposition D class digital power amplifier, mid-D class digital power amplifier and the rearmounted D class digital power amplifier and amplify processing, and then output to separately the set of speakers that connects separately and play.Because the power output of rearmounted D class digital power amplifier is larger than preposition D class digital power amplifier and mid-D class digital power amplifier, thus about the sound of rearmounted set of speakers louder, more outstanding.About rearmounted set of speakers be the surround sound loud speaker, surround sound increases, and has strengthened the third dimension of sound, sound effect is truer, brings more perfect hearing enjoying.
In order to eliminate this noise elimination when the utility model power on/off, between each digital power amplifier and set of speakers, be provided with speaker protection circuit, prevent that purified signal is to the impact damage of digital power amplifier.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
