Detailed description of the invention
Fig. 1 is the stereoscopic schematic diagram of the noise reducing sound box component of the embodiment of the present invention.
Wherein, 1, speaker body；2, directional audio collector；3, directional loudspeaker；4, directional communication antenna；5, orientation is logical
Believe antenna.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
As shown in connection with fig. 1, noise reducing sound box component of the invention is schematically showed, the speaker sheet including eight prism shapes
Body 1, speaker body 1 are equipped with eight orientation noise reduction modules, and eight orientation noise reduction modules are respectively provided at eight sides of speaker body 1
It is the center of circle with speaker body 1 on wall, 1 surrounding of speaker body is divided into eight noise reduction regions, each orientation noise reduction module is responsible for
The noise reduction work in one noise reduction region；Orienting noise reduction module includes the directional audio collector 2 and directional loudspeaker being disposed adjacent
3, perpendicular to the side wall of the speaker body 1 where it, directional audio collector 2 is responsible for for the radio reception direction of directional audio collector 2
The noise signal in the noise reduction region where it is acquired, the broadcast direction of directional loudspeaker 3 is perpendicular to the speaker body 1 where it
Side wall, directional loudspeaker 3 are responsible for the noise signal reverse phase that directional audio collector 2 collects being processed into antinoise signal,
And towards the noise reduction field emission antinoise signal where it, antinoise signal cancellation noise signal is utilized.According to the component
The limitation of working principle, closer to speaker body 1, obtained noise reduction effect is better, and people, which can choose, is placed in speaker body 1
Bedroom, study etc. need peace and quiet the place of environment.
Certainly, it can also add on the basis of the component and (not scheme for the feedforward audio collection device of acquisition noise signal
Show), feedforward audio collection device is on hardware independently of speaker body 1.The top of speaker body 1 is equipped with beam communication module, fixed
It include eight beam communication antennas 5 to communication module, the signal transmitting and receiving direction of eight beam communication antennas 5 is respectively parallel to eight
The broadcast direction of directional loudspeaker 3, feedforward audio collection device wireless communication are connected to beam communication antenna 5.In the reality of the component
In the work of border, user carries feedforward audio collection device, noise that user hears while can also be fed forward audio collection device and adopts
Collect.Feedforward audio collection device is merely able in a certain noise reduction region of speaker body 1 and is responsible for the noise reduction region beam communication
5 wirelessly transmitting data of beam communication antenna, so, speaker body 1 can by learning feedforward audio collection device
Which beam communication antenna 5 wireless data transmission is carried out with to judge feedforward audio collection device is in which drop of speaker body 1
It makes an uproar region, speaker body 1 can emit antinoise signal towards user by being responsible for the directional loudspeaker 3 in the noise reduction region.This
Outside, in order to which the noise signal and antinoise signal that enable user position are cancelled out each other, reach effectively noise reduction, speaker sheet
Body 1 can also compare the collected noise signal of both feedforward audio collection device and directional audio collector 2, according to two collectors
Between noise signal decaying difference calculate feedforward audio collection device and speaker body 1 approximate distance, further according to feedforward sound
The watt level of frequency collector and the antinoise signal to be launched of the distance analysis directional loudspeaker 3 of speaker body 1, so that
Antinoise signal can just decay when propagating to user site in the noise letter that can offset user site
Number, guarantee noise reduction effect.
In the present embodiment, baroceptor is equipped in speaker body 1, baroceptor is electrically connected at directional audio and adopts
Storage 2 measures the atmospheric pressure value of the component local environment using baroceptor, to calculate sound wave declining under the atmospheric pressure value
Subtract coefficient.The top of speaker body 1 is equipped with the directional communication antenna 4 for connecting internet, and directional communication antenna 4 is preferably
Wi-Fi antenna, noise reduction gain intensity of the user by the remote-controlled speaker body 1 of the modes such as cell phone application, personalized customization attribute
