    • Herein disclosed a suction cup including: a suction cup body having at least one surface having a gel, the surface being a suction surface; and an elastically deformable spring element provided in or on the suction cup body, having a concave shape so as to make the suction surface have a concave shape, and energizing a central part of the suction surface away from a surface to be sucked in the condition where the suction surface is in suction contact with the surface to be sucked, wherein the spring element is formed from a material having a modulus of elasticity higher than those of natural rubber and synthetic rubbers.
    • 这里公开了一种吸盘,其包括:吸杯体,其具有至少一个具有凝胶的表面,所述表面是吸力表面; 以及设置在吸盘主体内或上的可弹性变形的弹簧元件,其具有凹形,以使吸引表面具有凹形,并且使抽吸表面的中心部分远离待吸附表面的状态 其中吸入表面与待吸附的表面进行吸力接触,其中弹性元件由弹性模量高于天然橡胶和合成橡胶的材料形成。

    • A speaker of a type having a voice coil wound to a greater length than the length of a magnetic gap into which it extends formed between a pole of a yoke and an annular plate. A magnetic flux density setting structure is provided for establishing a constant value of Bl, where B represents the density of the magnetic flux capable of linking the voice coil and l represents the effective length of the voice coil. The magnetic flux density setting structure may be formed as a tapered surface or surfaces on the pole of the yoke or by a separate tapered plate or plates attached to the annular plate. Further, a metal cap is mounted on the pole covering an upwardly facing cup-shaped body of magnetic material.
    • 具有缠绕在比磁轭的长度大的长度的音圈类型的扬声器,其延伸形成在磁轭的磁极和环形板之间。 提供磁通密度设定结构用于建立B1的恒定值,其中B表示能够连接音圈的磁通量的密度,l表示音圈的有效长度。 磁通密度设定结构可以形成为轭的极的锥形表面或表面,或者形成为附接到环形板的单独的锥形板或板。 此外,金属盖安装在杆上,覆盖面向上的杯状磁性材料体。
