Curved strip-shaped display device (eg telephone)

A strip-shaped display device, such as a telephone, can have a unique and simple shape - this is necessary to quickly differentiate products in a crowded space. Figures 6 and 7 show examples. The strip-shaped display device may have a concave front side and a convex back side. The magnitude of the curvature of the two faces can be the same or similar. The recessed front surface can match the path of the finger when the user's wrist is rotated. Therefore, it is very natural to use. Moreover, when the speaker of a distributed mode loudspeaker (DML) vibrates, it has a better surface, because if the front display with the speaker exciter is changed to a plane, if the plane is placed downward facing the table, it will It doesn't sound pleasant. Surfaces prevent this from happening. The preferred curvature of the front and back screens is cylindrical, but it can also be Spherical or aspherical. The raised back side can have a bi-stable display. Since the normal rest position is face down, the back screen with the bi-stable display is normally displayed when the strip-shaped display device is in the rest position. This rest position is mechanically stable. If the strip-shaped display device is placed with the back side down (i.e., the convex surface faces downward), the strip-shaped display device can be rotated, which is unstable. Therefore, the user will likely place the front side (i.e., the concave side) of the strip-shaped display device downward to present a bi-stable screen.

If the strip-shaped display device is in the pocket, the front side (concave surface) can face inward as this better matches the curvature of the leg. This pair of antenna receptions can be a better structure (as opposed to facing outwards).

In manufacturing, the curved shape may be a laminated glass.

DML strip shaped display device (eg telephone) speaker

Unless you have large speakers and large, unsightly speaker holes, it is difficult to get high quality audio performance.
