Embodiment
One embodiment of the present invention is described in detail referring to the drawings.
The lift facility of present embodiment is illustrated with reference first to Fig. 1.As shown in figure 1, in the elevator of lift facility
The upper and lower part of car 2 is respectively arranged with airspace, and loudspeaker 7 and microphone 4 are provided with airspace.
Microphone 4, which is detected under the control of control device 5 described later from the liftway of lift facility, enters lift car 2
Interior noise 3.On the other hand, loudspeaker 7 produces the noise phase that phase is detected with microphone 4 under the control of control device 5
Anti- sound equipment.
The top 10 of lift car 2 is provided with control device 5 and instrument box (BOX) 6.Control device 5 has Mike
The sound that wind 4 is detected is converted to the signal of opposite in phase, and the letter for the opposite in phase for producing and converting from loudspeaker 7
The function of number corresponding sound equipment.Microphone 4 and loudspeaker 7 are connected by cable with control device 5.
Control device 5 obtains power supply, lasting detection from the instrument box (BOX) 6 being arranged on the lift car of lift facility
Noise 3 out of airspace enters lift facility lift car 2, and continue through the production in lift car 2 of loudspeaker 7
The sound equipment of raw opposite in phase.
In addition, as shown in figure 3, in the airspace of lift car 2, top 10 and cage side on the top of lift car 2
Multiple positions between the side side plate 8 of plate part are provided with ventilation distance piece (distance piece) 11.In addition, in electricity
Multiple positions between the top 10 on the terraced top of car 2 and the back side side plate 9 of car back portion are provided with ventilation distance piece
11。
In addition, as shown in figure 4, in the bottom of lift car 2, in skirt plate portion 13 and the car side plate of car floor
Multiple positions between side side plate 8 are provided with ventilation distance piece 11.Also, carried on the back in the skirting board 13 of car floor with car
Multiple positions between the back side side plate 9 of face part are provided with ventilation distance piece 11.
Cover body 12 is set on the side plate towards liftway, while necessary airspace is ensured, by noise 3
It is arranged to labyrinth structure into passage.According to this structure, the approach axis of noise 3 can be limited, and can easily lead to
Cross microphone 4 and detect noise.
Because the noise that the front side in lift car 2, center side and rear side are produced is different from each other, so can also be in electricity
Multiple positions above multiple positions, the car of the side of lift car 2, the back side below the car of the side of terraced car 2
Multiple positions below car and multiple positions above the car at the back side set microphone and loudspeaker, to detect respectively
Noise, and produce the sound equipment of opposite in phase.
For example, can be with as shown in figure 5, setting multiple wheats respectively in the side and the back side on the top (section DD) of lift car 2
Gram wind and loudspeaker, and multiple microphones can also be set in the side and the back side of the bottom (section EE) of lift car 2 respectively
And loudspeaker.Thus, it is possible to which all positions in lift car 2 obtain noise reducing effect.
Furthermore, it is possible to set multiple microphones on the top or bottom of lift car 2 or top and bottom and raise
Sound device, and the setting quantity of microphone and loudspeaker can also be changed according to the size of lift facility.For example, being set in elevator
When standby depth size is big or when top is high, it can further increase the setting quantity of microphone and loudspeaker.In addition, also may be used
Change setting quantity, set location or setting interval of microphone and loudspeaker etc. with the shape according to lift car.
In the present embodiment, microphone detection noise is continued through, and phase is produced with detecting by loudspeaker
The opposite sound equipment of noise, but it is also possible to be arranged to make microphone detect noise according to prespecified normal speed, and lead to
Cross the sound equipment that loudspeaker produces opposite in phase.
In addition it is also possible to produce opposite in phase by loudspeaker when being arranged to only multiply passenger seated 1 in lift car 2
Sound equipment, and can also be arranged to only produce the sound of opposite in phase by loudspeaker when detecting the noise of more than prescribed level
Ring.Thereby, it is possible to prevent from unnecessarily making loudspeaker to produce sound equipment, the noise in lift car can be effectively reduced.
Be arranged on being used in airspace detect the microphone 4 of noise relative to lift car 2 towards outside (towards rising
Passage drops) sets, and the loudspeaker 7 for producing the sound equipment of opposite in phase is configured to the inner side setting towards lift car.Thus, energy
It is enough more effectively to detect noise, sound equipment corresponding with the noise detected can be produced.
In addition, loudspeaker 7 is configured to cover ventilation unit by car side plate so that the passenger 1 in lift car 2 sees
Less than loudspeaker 7, thus, it is possible to prevent passenger 1 from moving back and forth loudspeaker 7 etc..Also, can also raising the top 10 of lift car 2
Sound device 7 is arranged to using ligthing paraphernalia or the grade of the decoration at top 14 so that the passenger 1 in lift car 2 cannot be directly viewed and raise
Sound device 7, to prevent passenger from moving back and forth loudspeaker 7.
