Upstream and downstream, upstream hydrophone are connect by connecting line with wireless communication module, and downstream hydrophone passes through connecting line and broadband
The connection of noise control module, the underwater acoustic transducer are mounted on the sewer pipe near the hydrophone of downstream, and underwater acoustic transducer is logical
Cross connecting line connect with broadband noise control module and pass through power amplifier drive itself work.
Further, the periphery of the upstream hydrophone and downstream hydrophone is equipped with pod.
Further, the reference sensor of the mute subsystem in the space is left microphone, and error pick-up is right transaudient
Device, secondary source are loudspeaker, and microphone and loudspeaker pass through connecting line respectively and connect with broadband noise control module, and loudspeaker is logical
Overpower amplifier drives and itself works.
The utility model has the advantages that
1, the present invention takes full advantage of the wireless communication and igh-speed wire-rod production line function of smart home epoch smart phone, will
It carries out active vibration and noise reducing control as a typical active controller, and water closet noise can be effectively reduced to week
The interference in collarette border.
2, the present invention can substantially reduce the hardware cost of Active control.On the other hand popularizing with smart phone, should
System can further promote the popularization and application of active noise reduction technology.

Specific embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
Attached drawing 1 is that the intellectual mute water closet drainage pipeline Noise Active control wirelessly connected is shown
It is intended to；The part can carry out Active control to closestool drainage pipeline noise.In the control of closestool drainage pipeline Noise Active, adopt
Use underwater acoustic transducer 3 as control sound source, upstream hydrophone 1 and downstream hydrophone 4 respectively as error pick-up and with reference to biography
Sensor.
The part further includes power amplifier 5, broadband noise control module I 6, wireless communication module I 7 and smart phone 8.
The working method of closestool drainage pipeline Noise Active control is as follows:
Upstream hydrophone 1 is used to acquire the noise signal of water closet drainage pipeline upstream.Collected reference signal warp
Connecting line is transferred to wireless communication module I 7.Signal is sent after the coding of wireless communication module I 7, and is received simultaneously by smart phone 8
Decoding.Decoded signal is handled through Active control program internal in smart phone, is inputted as reference signal.
Downstream hydrophone 4 is used to acquire the noise signal in water closet drainage pipeline downstream, and will adopt through signal connecting line
