    • A speaker comprising a first rod magnet having a longitudinal direction, a second rod magnet having a longitudinal direction parallel with the longitudinal direction of the first rod magnet, a third rod magnet forming a second magnetic gap between it and the first rod magnet, a diaphragm vibrating in the vibrating direction, a housing for storing the first rod magnet, the second rod magnet, the third rod magnet and the diaphragm, and voice coils bonded to the diaphragm and arranged in first and second magnetic gaps. The second rod magnet has a longitudinal direction parallel with the longitudinal direction of the first rod magnet, and has the opposite end faces in the longitudinal direction. The third rod magnet has a longitudinal direction parallel with the longitudinal direction of the first rod magnet, and has the opposite end faces in the longitudinal direction. The diaphragm is located between the first and second rod magnets and between the first and third rod magnets. The housing forms a first space surrounded by one of the opposite end faces of the second rod magnet and one of the opposite end faces of the third rod magnet, and forms a second space surrounded by the other of the opposite end faces of the second rod magnet and the other of the opposite end faces of the third rod magnet. The housing is composed of a nonmagnetic body and supports the outer circumference of the diaphragm. First and second sound radiating holes respectively facing the first and second spaces are formed in the housing. This speaker is thin and can deliver big sound.
    • 一种扬声器,包括具有纵向方向的第一杆状磁体,具有与第一杆状磁体的纵向方向平行的纵向方向的第二杆状磁体,在其与第一杆状磁体之间形成第二磁性间隙的第三杆状磁体, 在振动方向上振动的壳体,用于存储第一杆状磁体,第二杆状磁体,第三杆状磁体和隔膜的壳体,以及与隔膜接合并设置在第一和第二磁隙中的音圈。 第二杆状磁体具有与第一杆状磁体的长度方向平行的长度方向,并且在长度方向上具有相对的端面。 所述第三杆状磁体具有与所述第一杆状磁体的长度方向平行的长度方向,并且在所述长度方向上具有相对的端面。 隔膜位于第一和第二杆状磁体之间以及第一和第三棒状磁体之间。 壳体形成由第二杆状磁体的相对端面之一和第三杆状磁体的相对端面之一围绕的第一空间,并形成第二空间,该第二空间被第二杆的相对端面中的另一端面包围 磁体和第三杆磁体的另一个相对端面。 外壳由非磁性体构成,并支撑隔膜的外周。 分别面对第一和第二空间的第一和第二声音辐射孔形成在壳体中。 这个扬声器很薄,可以发出很大的声音。

    • When a pressure receiving plate provided at a seat back moves to a rear side of a vehicle body when a vehicle is collided from behind, a Bowden cable transmits movement of the pressure receiving plate to a headrest ascending mechanism as a tensile load, thereby quickly ascending a headrest to reliably hold a head of an occupant. The Bowden cable transmits only the tensile load, and hence the Bowden cable is not buckled. Reduction in weight is made possible as compared with the case using a rod for transmitting a compression load. Since the Bowden cable is light, it is not required to unreasonably place the pressure receiving plate at a position near the headrest ascending mechanism for reduction in weight, and hence the pressure receiving plate can be placed at the optimal position where a sufficient driving force is obtained at the time of collision. Thus, a headrest is ascended with favorable responsiveness upon a rear-end collision of a vehicle while using a thin transmission member with low rigidity.
    • 当车辆从后方碰撞时,设置在座椅靠背处的受压板移动到车体的后侧时,鲍登缆索将压力承受板的运动作为拉伸载荷传递到头枕上升机构,由此快速上升 头枕可靠地保持乘员头部。 鲍登电缆仅传输拉伸载荷,因此鲍登缆线不会弯曲。 与使用用于传送压缩载荷的杆的情况相比,能够减轻重量。 由于鲍登缆线很轻,不需要将压力承受板不合理地放置在靠近头枕上升机构的位置,以减轻重量,因此压力接收板可以放置在最佳位置,在该最佳位置,足够的驱动力为 在碰撞时获得。 因此,在使用低刚性的薄型传动部件的情况下,在车辆的后方碰撞时,头枕具有良好的响应性。
