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

Abstract: PROBLEM TO BE SOLVED: To enlarge the amplitude of a vibrating surface in simple configuration, with respect to a planer acoustic transducer and a method of manufacturing the planer acoustic transducer.
SOLUTION: Even when a vibrating surface 112 of a vibrating film 110 is displaced up and down, namely, even when driving surfaces 114, 115 are displaced up and down, a density of magnetic flux passing the driving surfaces 114, 115 is not changed. Thus, a width of displacement of the vibrating surface 112 can be enlarged. Therefore, sound pressure can be increased more easily than the prior art. Furthermore, lower-register reproducibility also becomes excellent. Moreover, the vibrating surface 112 and the driving surfaces 114, 115 are formed by folding one vibrating film 110, so that the configuration is simplified and manufacturing is also facilitated.

Abstract: PROBLEM TO BE SOLVED: To provide clothing with a speaker having a sound source to naturally and clearly emit sound from an electroacoustic device.
SOLUTION: A speaker unit 12 provided with a flat diaphragm is placed between first cloth 26 and second cloth 28, the first cloth 26 and the second cloth 28 are sawn together, and the male member 32 of a Hook-and-Loop fastener is sawn to the outer face of the first cloth 26. Since the clothing-fitting speaker system 10 is provided with the male member 32 of the Hook-and-Loop fastener, the system 10 can simply be fixed to cloth such as a vest and simply be removed therefrom. When the clothing-fitting speaker system 10 is fixed to both shoulders of the vest, a person wearing the vest can hear the sound of plane waves delivered directly upward from speaker units 12 located at places nearly beneath both the ears and also hear environmental noises traveling/propagating laterally, in forward/backward directions or the like at the same time with both the ears.

Abstract: PROBLEM TO BE SOLVED: To provide a portable sound station which is so thin that the portable sound station does not take up much space when placed in a bag or the like, easy to carry, and so versatile that the portable sound station can be used in a large variety of manners.
SOLUTION: The portable sound station is constituted of a flat main body portion 12 with built-in power switch 20, volume control 24, power amplifier, input terminal, battery, and the like; and a first flat speaker 14 and a second flat speaker 16 which incorporate a flat speaker unit and are coupled with the main body portion 12 through a pipe 48. The first speaker 14 and the second speaker 16 are supported on the pipe 48 so that the speakers can be rotated against the main body portion 12 and moved close to and away from the main body portion 12. When the first speaker 14 and the second speaker 16 are moved and brought into contact with both the sides of the main body portion 12, the speakers and the main body portion form a single plate. In this state, the portable sound station is so thin that the portable sound station does not take up much space when placed in a bag or the like and is easy to carry. In addition, since the fist speaker 14 and the second speaker 16 as coupled with the main body portion 12 can be moved, the portable sound station can be used in a large variety of manners.
