摘要:
A vehicle seat is provided comprising a seat back frame having right and left side frames, a headrest for supporting a head of a seat occupant, and a back-and-forth movable body provided inside a backrest that is positioned at a rear of the seat occupant, wherein a backward movement of the back-and-forth movable body forwardly moves the headrest to support the head of the seat occupant. The back-and-forth movable body is attached to each side frame through a link member and is provided with a backward protrusion protruding backward, and the backward protrusion extends laterally.

An edge (29) for supporting a diaphragm assembly (100) with respect to a frame (26) is bonded to the frame (26) along the outer periphery thereof and joined to a diaphragm (27) in a position more peripherally inward than a voice coil (28) along the inner periphery thereof. The edge (29) partly overlaps diaphragm (27). This structure allows downsizing of the speaker, without reducing the sizes of a permanent magnet (21) and the edge (29).

A voice coil wound to have a loop having an inner side is fixed to a diaphragm vibrating in a vibration direction. A first magnet having a first pole surface is fixed to an upper case. A second magnet having a second pole surface is fixed to a lower case. A first magnetic fluid is attached to the first pole surface of the first magnet after fixing the first magnet to the upper case. The diaphragm is fixed to the upper case after fixing the voice coil to the diaphragm and after attaching the first magnetic fluid to the first pole surface of the first magnet, such that the first pole surface of the first magnet faces the inner side of the voice coil and that the first magnetic fluid is provided between the first pole surface of the first magnet and the voice coil and contacts the first pole surface and the voice coil.

A vehicle seat of the invention includes: a rectangular-shaped seat back frame (5) having a pair of side frames (6); a plurality of seat springs (34A, 34B) disposed between the side frames; a single plate-shaped flexible cushion plate (31) attached to the seat springs; a seat cushion (9) provided on the front side of the cushion plate; link mechanisms (15, 35) provided near the side frames; and a headrest (4) coupled to the link mechanisms (15). Both ends of the seat spring (34B) are coupled to the link mechanisms. When the seat spring (34B) is moved rearward, the headrest is moved forward. Both sides of each of the remaining seat springs (34A) are mounted to the side frames.

The speaker design support apparatus can reduce time for designing the speaker instead of many design trials, and comprises the input means that a user inputs necessary data for voice coil and for magnetic circuit and for diaphragm, and the calculation means for calculate the speaker characteristic based on the inputted data from the input means, and the display for displaying the calculated results by the calculation means.
摘要:
A suspension with a plurality of roll sections each of which has a semi-cylindrical shape from a cross-section view. The roll sections are disposed side by side based on a straight line connecting two points on an inner periphery or an outer periphery. The roll sections form a closed loop in a manner that a roll section of the roll sections being disposed first adjoins a roll section of the roll sections being disposed last. Adjacent roll sections are coupled with each other through a boundary section forming a continuous three dimensional curved surface. A linearity of compliance improves, and generation of distortion or rolling is restricted using the suspension.
