Investigation has shown that the problem of high noise level is particularly apparent when the toilet is used at night, and the problem can adversely affect the noise in the surrounding environment to disturb the sleeping of people. Thus, there is a need for effective treatment of toilet noise.
On the one hand, the traditional noise control technology reduces the noise level from the source by improving the noise source structure, and currently, the siphon type water closet belongs to the class. On the other hand, noise is absorbed and blocked by a mode of laying sound absorbing and insulating materials. This solution requires more space and is currently still more difficult to apply to toilet products. Active noise control is a novel noise control technique. Compared with the traditional noise control technology, the noise control method has the characteristics of small equipment size and good noise control effect, and has been paid attention to in recent years. Currently, active control technologies, represented by active noise abatement of pipes, are becoming mature and are applied in succession in some products.

Detailed Description
The invention will now be described in detail by way of example with reference to the accompanying drawings.
FIG. 1 is a schematic diagram of an intelligent silent toilet bowl sewer line noise active control by wireless connection; this portion can actively control the toilet drain line noise. In the active control of the noise of the toilet sewer line, the underwater acoustic transducer 3 is adopted as a control sound source, and the upstream hydrophone 1 and the downstream hydrophone 4 are respectively adopted as an error sensor and a reference sensor.
The part also comprises a power amplifier 5, a broadband noise control module I6, a wireless communication module I7 and a smart phone 8.
The working mode of the noise active control of the toilet sewer line is as follows:
the upstream hydrophone 1 is used to collect noise signals upstream of the toilet's sewer line. The acquired reference signals are transmitted to the wireless communication module I7 through a connecting wire. The signal is encoded by the wireless communication module I7 and then transmitted, and is received and decoded by the smart phone 8. The decoded signal is processed by an active control program in the smart phone and is input as a reference signal.
The downstream hydrophone 4 is used for collecting noise signals downstream of the sewer line of the toilet bowl and transmitting the collected signals to the broadband noise control module I6 and the wireless communication module I7 through signal connecting lines. The signal passes through a broadband noise control module I6 to generate a control output signal, and drives the underwater acoustic transducer 3 to work through a power amplifier 5. This portion is used to control the random broadband noise portion of the downcomer noise.
On the other hand, the error signal collected by the downstream hydrophone 4 is encoded and transmitted by the wireless communication module I7, and received by the smart phone 8. Processed by an active control program inside the smart phone 8 and is input as an error signal. The processing program in the smart phone 8 takes as input the signals collected by the upstream hydrophone 1 and the downstream hydrophone 4, and obtains a control output signal. The control output signal is sent by the smart phone after being encoded, received by the wireless communication module I7 and decoded. The decoded signal drives the underwater acoustic transducer 3 to work through the power amplifier 5, thereby realizing the active control of the periodic noise of the sewer line of the water closet.
Fig. 2 is a schematic diagram of active control of human ear position noise above an intelligent silent toilet connected by wireless. The part comprises: a microphone 10 used as an error sensor, a speaker 9 used as a secondary source, a power amplifier 5, a broadband noise control module ii 11, a wireless communication module ii 12, and a smart phone 8.
In the invention, the active control of the noise of the sewer line of the toilet bowl is similar to the active control of the noise of the human ear above the toilet bowl in operation mode, and the difference is mainly that an error sensor of the active control part of the noise of the human ear above the toilet bowl is a microphone, and a secondary source is a loudspeaker. The system has the functions of noise control and music playing. In active control of the noise in the position of the human ear, two microphones 10 and two loudspeakers 9 need to be arranged above the toilet.
In summary, the above embodiments are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention.
