    • A speaker apparatus includes an elliptical-shaped or a round-edged rectangular-shaped vibration plate; an edge damper portion disposed on an outer peripheral edge portion of the vibration plate; a recessed portion formed between said vibration plate and said edge damper portion, having a caliber of a shape corresponding to the shape of said vibration plate; and an air core voice coil fitted into an interior of said recessed portion. The speaker apparatus further includes a frame for mounting said edge damper portion to support said vibration plate, having a stepped portion and a vertical wall portion; and an edge damper frame arranged on an outer periphery of said edge damper portion, having a support portion placed on the stepped portion and a rising portion being in contact with the vertical wall portion.

    • A butterfly damper for preventing an adhesion surface between a speaker frame (6) and an outer peripheral frame (12) from peeling off is provided. The butterfly damper comprises an inside peripheral flame (11), an outer peripheral flame (12) and a plurality of movable arms (13), all of which are formed in a single piece by injection molding of thermoplastic synthetic resin. The thickness T of the outer peripheral flame (12) is thicker than the thickness t of the movable arms (13). In addition, the front and back faces of the outer peripheral flame (12) are formed so that each face protrudes toward the thickness direction respectively from the front face and the back face of the movable arms (13).
    • 提供了用于防止扬声器框架(6)和外周框架(12)之间的粘合表面剥离的蝶形阻尼器。 蝶形阻尼器包括内部周边火焰(11),外周火焰(12)和多个可动臂(13),所有这些都通过热塑性合成树脂的注射成型而形成为一体。 外周火焰(12)的厚度T比活动臂(13)的厚度t厚。 此外,外周火焰(12)的前表面和后表面形成为使得每个面分别从可动臂(13)的前表面和后表面朝向厚度方向突出。

    • A method for opening, closing and rotating a rigid marine sail, which comprises the steps of: selectively opening, closing and rotating, in response to a wind velocity and a wind direction, a rigid sail comprising at least two sail portions which are fitted in front of a mast rotatable around the vertical axis thereof substantially in parallel with said axis, and which are selectively pivotably movable between the opened position and the closed position relative to the mast: the method being characterized by: smoothing a plurality of wind velocity signals and a plurality of wind direction signals from a wind velocity/wind direction meter, by a calculating device at prescribed intervals of time; determining opening and closing of the at least two sail portions by the calculating device on the basis of smoothed wind velocity signals and smoothed wind direction signals; automatically selectively opening or closing the at least two sail portions by an opening/closing device in response to the determination; determining by the calculating device an optimum sail angle relative to the horizontal reference line of the ship, the optimum sail angle providing the maximum propulsion to the at least two sail portions when the sail portions are opened, and minimizing the wind resistance acting on the at least two sail portions when the sail portions are closed; and, selectively rotating the mast together with the at least two sail portions, by a mast rotating mechanism, in response to the deviation of an actual sail angle relative to the horizontal reference line of the ship from the optimum sail angle, thereby always keeping the at least two sail portions at the optimum sail angle.
    • 一种用于打开,关闭和旋转刚性海洋帆的方法,其包括以下步骤:响应于风速和风向选择性地打开,关闭和旋转;刚性帆,包括至少两个帆形部分,其装配在 所述桅杆的前部可绕其垂直轴线大致平行于所述轴线旋转,并且其可相对于所述桅杆在打开位置和关闭位置之间选择性地可枢转地移动。所述方法的特征在于:平滑多个风速信号和 来自风速/风向计的多个风向信号通过计算装置以规定的时间间隔; 基于平滑的风速信号和平滑的风向信号,通过计算装置确定至少两个帆部分的打开和关闭; 响应于所述确定,通过打开/关闭装置自动选择性地打开或关闭所述至少两个帆部; 由所述计算装置确定相对于所述船的水平参考线的最佳帆角,所述最佳帆角在所述部分打开时向所述至少两个帆形部分提供最大推进力,并且最小化作用在所述船上的所述风阻力 当帆部分关闭时,至少两个帆部分; 并且响应于相对于最佳帆角相对于船舶的水平参考线的实际帆角的偏差,通过桅杆旋转机构选择性地将桅杆与至少两个帆部分一起旋转,从而始终保持 至少两个帆部分处于最佳帆角。
