Description
Technical field
The present invention relates to intelligent sound fields, and in particular to a kind of intelligent sound that transfer audio is carried out based on Bluetooth transmission
System.
Background technique
Smart home industry at this stage, intelligent sound box have covered most market, and single intelligent sound box can only
The confined space is confined to be controlled, such as: if placing intelligent sound box in bedroom, leaving can not be to intelligent sound after the range of bedroom
Case is manipulated, it is assumed that is also required to carry out manipulation voice in parlor, then needing in addition to add an intelligent sound box in parlor, such as
This one, increase intelligent sound box and not only increase load to router and increase the expense of speaker bought.By data statistic analysis,
Intelligent sound box occupation rate of market is very high in smart home industry at present, but cost remains high always, for a user, at
The problem of this is always user's concern.
When the work of intelligent sound box, wheat column are in pickup state (persistently sampled, quantified to voice signal) always.Into
It crosses basic signal processing (mute detection, noise reduction etc.), wake-up module determines whether occur waking up word, if so, subsequent language
Sound will do it more complicated Speech processing and obtain clean voice signal, start real interactive voice process.According to ring
The influence of noise in border, there are also speakers at a distance from sound source, it is assumed that speaker play music environment or play TV under the influence of,
The accurate rate of identification can reduce, and most critical is that the distance beyond 3-5 meters of pickup range can not just be identified, according to existing skill
Art limitation, can only increase more intelligent sound boxes and make up the technological deficiency beyond distance range, but increase the cost of speaker without
It doubts and gives the certain cost pressure of user.Current intelligent sound box does not have the function with the dialogue of other intelligent sound boxes, that is,

3-5 meters of pickup range of virtual value of intelligent sound box currently on the market, due to consideration that without wall barrier or
Under the influence of signal environment factor etc., accomplish that the universal range in widened each room or region can only be by addition intelligence if necessary
The mode of speaker covers speech range, but the cost payout for increasing intelligent sound box is more compared to will increase originally, if adding intelligence
Energy speaker has to the bandwidth certain in the range and occupancy network of router covering, can pass through classics according to such case
Bluetooth transfer techniques transfer voice reaches expansion grammatical coverage.Since the equipment of single bluetooth module pairing is limited, effectively
Theory pairing slave devices amount is 7-8 slave devices amount.According to scenario analysis, it is assumed that intelligent sound box has been filled in bedroom, if
User must add new if necessary to progress speech control in other region and room, user in the range of router covers
Intelligent sound box reaches control effect.Technically, unilaterally by bluetooth band machine amount promotion technically realize it is very difficult,
It is that can not accomplish that multi-to-multi is communicated on single bluetooth module, it is blue according to current 4.0 agreement of bluetooth or 4.1 or more high speed
