Abstract: PROBLEM TO BE SOLVED: To provide a train noise reducing device which can reduce train noise. SOLUTION: A sound-proof wall 16 is disposed upright on a roof of a train so as to surround a pantograph 14. Almost the whole of right and left side walls 16A is constituted by using a plurality of plane speaker units 24 for generating a plane wave. A microphone 44 is fixed on the roof 12. The microphone 44 and the plane speaker units 24 are connected with a control unit 48. Based on noise N detected at the microphone 44 (noise generated when the pantograph 14 slides to a wire 46), a control part 48 drives the plane speaker units 24 in such a manner that a cancelling sound UN of an antiphase with the noise N is generated. The cancelling sound UN outputted from the plane speaker units 24 and the noise N (diffraction sound) which has carried out diffraction by the upper end 16A of the sound proof wall 16 overlap with each other, so that the noise level of the train exterior sound proof wall 16 is reduced.

Abstract: PROBLEM TO BE SOLVED: To simplify a manufacturing process.
SOLUTION: Each magnet 12 is disposed between projections 100 on a bottom surface 14A of a yoke 14 so as to be located at a predetermined position. Furthermore, a magnetic pole face of each magnet 12 is adsorbed on the bottom surface 14A with a magnetic force so as to be fixed. Therefore, when performing recycling work after collecting a flat speaker 10 from the market, the magnetic 12 can be easily detached. Moreover, it is not necessary to remove adhesives left on the magnets 12 and the yoke 14, either. Namely, disassembly of the magnets 12 and the yoke 14 is facilitated. In such a case, since no adhesive is stuck, the yoke 14 is melted and can also be easily recycled as metal row materials. Furthermore, since it is enough only to dispose each magnet 12 between the projections 100 on the bottom surface 14A of the yoke 14, manufacturing steps are simplified. Moreover, since it is not necessary to leave the magnets and the yoke until the adhesives are hardened, the manufacturing time is shortened.

Abstract translation: 要解决的问题：简化制造过程。 解决方案：每个磁体12设置在轭14的底表面14A上的突起100之间，以便位于预定位置。 此外，每个磁体12的磁极面以磁力被吸附在底表面14A上以便被固定。 因此，当从市场上收集扁平扬声器10之后进行再循环工作时，可以容易地拆卸磁性体12。 此外，也不需要去除残留在磁体12和磁轭14上的粘合剂。 也就是说，易于拆卸磁体12和磁轭14。 在这种情况下，由于没有粘合剂粘合，轭14熔化并且也可以容易地作为金属排料再循环。 此外，由于只要将磁铁12配置在磁轭14的底面14A上的突起部100之间，就简化了制造工序。 此外，由于在粘合剂硬化之前不需要离开磁体和磁轭，所以制造时间缩短。 版权所有（C）2008，JPO＆INPIT
