Abstract: Improvements in oscillating reeds particularly for use in generating a sweeping or oscillating air flow pattern. The oscillating reeds of this invention are constituted by a plurality of spaced apart resilient reed elements (12-1, 12-2 and 12-3) which, preferably, are made from graphite fibers bonded together by an epoxy resin matrix reinforced by a scrim of fiber glass. To minimize the effect of torsion and/or forces which can cause the reed elements to buckle and hence create noise, a plurality of undulations (30) are formed in the graphite strip. Thus, the oscillating reed (10) according to the present invention offers the following four major advantages, (1) reduction in noise from buckling, (2) amplitude modulation, i.e. oscillation amplitude insensitivity to wide ranges of flow rates, (3) easier starting of oscillation, and (4) improved fatigue strength.

Abstract translation: 振荡簧片的改进，特别是用于产生清扫或振荡空气流动模式。 本发明的摆动簧片由多个间隔开的弹性簧片元件（12-1,12-2和12-3）构成，弹簧簧片元件（12-1,12-2和12-3）优选由石墨纤维制成，该石墨纤维由被稀松布增强的环氧树脂基体 的玻璃纤维。 为了最小化扭矩和/或力的影响，其可以导致簧片元件弯曲并因此产生噪音，在石墨条中形成多个起伏（30）。 因此，根据本发明的振荡簧片（10）具有以下四个主要优点：（1）降低压缩噪声，（2）振幅调制，即振荡幅度不敏感性到宽范围的流量，（3）更容易 振荡开始，（4）提高疲劳强度。
