Description
Technical field
This utility model is related to around sound technique field, particularly a kind of multi-function desktop bluetooth surround speaker.
Background technology
Traditional sound system device structure typically can only realize a kind of sound power amplifier effect, simultaneously nor with moveable
Desktop Baffle Box of Bluetooth forms stereo-circulation acoustics, and also has the sound system by software and combination of hardware on the market, leads to
Cross Software Coding control mode, enable to loudspeaker and there is muli-sounds power amplifier effect, but it adopts software mode to sound
Signal is recompiled, and easily the threshold values of highest or lowest audio frequency is filtered, and therefore easily produces distortion, therefore sound
Power amplifier effect is bad.
Content of the invention
In order to overcome the disadvantages mentioned above of prior art, the purpose of this utility model is to provide a kind of sound equipment resource to make full use of
, build simple and convenient and low cost, have that stereo-circulation is acoustic, also there are many work(of home theater effect simultaneously
Can desktop bluetooth surround speaker
This utility model solves its technical problem and be employed technical scheme comprise that：
A kind of multi-function desktop bluetooth surround speaker, wherein：Including audio distribution processing system and Bluetooth audio device, described sound
Frequency division is joined processing system and is included signal input part and signal output part, and described signal output part is connected with some monaural power and puts
Big device, described monaural power amplifier outfan is all connected with power amplifier loudspeaker, and described audio distribution processing system also includes intelligence
Energy control module, DSP signal processing module, bluetooth module, frequency dividing circuit module and multi-channel decoding circuit module, described DSP
Signal processing module connects intelligent control module, bluetooth module, frequency dividing circuit module and multi-channel decoding circuit module, described indigo plant
Tooth audio amplifier is connected with bluetooth module by wireless signal, described frequency dividing circuit module and multi-channel decoding circuit module all with signal
Outfan connects.
As further improvement of the utility model：The signal output part of described audio distribution processing system is connected with six
Monaural power amplifier.
Compared with prior art, the beneficial effects of the utility model are：This utility model can be processed by audio distribution
System is connected with small-sized Baffle Box of Bluetooth on desktop, can make full use of existing Bluetooth audio device resource, by moveable bluetooth
Flexibly putting so that being capable of stereo-circulation acoustics with the cooperation of audio distribution processing system of audio amplifier, also can simultaneously
Separately through the multi-channel decoding circuit module crossing audio distribution processing system, defeated to signal by multi-channel decoding circuit module
Six monaural power amplifiers going out end export confidence in left high-frequency signal, left low frequency signal, left center signal and the right side respectively
Number, right low frequency signal, right high-frequency signal, complete the left and right sound channels of traditional-family's movie theatre and the home theater sound effect of voice.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
A kind of multi-function desktop bluetooth surround speaker, wherein：Including audio distribution processing system and Bluetooth audio device, described sound
Frequency division is joined processing system and is included signal input part and signal output part, and described signal output part is connected with six monaural power and puts
Big device, described monaural power amplifier outfan is all connected with power amplifier loudspeaker, and described audio distribution processing system also includes intelligence
Energy control module, DSP signal processing module, bluetooth module, frequency dividing circuit module and multi-channel decoding circuit module, described DSP
Signal processing module connects intelligent control module, bluetooth module, frequency dividing circuit module and multi-channel decoding circuit module, described indigo plant
Tooth audio amplifier is connected with bluetooth module by wireless signal, described frequency dividing circuit module and multi-channel decoding circuit module all with signal
Outfan connects.
This utility model makes full use of existing idle Bluetooth audio device resource, by audio distribution processing system with existing
Baffle Box of Bluetooth resource can form stereo-circulation acoustics, controls DSP signal processing module by intelligent control module so that believing
After number divided circuit module is processed, six monaural power amplifiers of outfan are exported respectively with left high-frequency signal, left
Frequency signal, left low frequency signal and right low frequency signal, right intermediate-freuqncy signal, right high-frequency signal, complete tradition simple left and right sound channels output
Clear stereo effect, be connected with portable Baffle Box of Bluetooth by bluetooth module simultaneously, by adjust Bluetooth audio device
Putting position is so that it may realize stereo-circulation acoustics.
In sum, after those of ordinary skill in the art reads this utility model file, according to skill of the present utility model
Art scheme and technology design need not creative mental work and make other various corresponding conversion scheme, belong to this practicality newly
The scope that type is protected.
