摘要： The present invention relates to an electrostatic speaker including a fixed electrode and a diaphragm that is arranged with a predetermined gap from the fixed electrode and has a plurality of ventilation holes. The ventilative diaphragm reduces air resistance caused by the ground effect between the fixed electrode and the diaphragm, and increases the sound pressure output from the speaker. As a result, the ventilative diaphragm makes it possible to obtain a uniform frequency reproduction characteristic over the entire frequency range. In particular, when the diaphragm is made from Korean paper, it is possible to effectively reduce the ground effect occurring between the fixed electrode and the diaphragm due to the air permeable characteristic of the Korean paper and the air resistance due to a surge input signal, while satisfying physical characteristics of the existing diaphragm. In addition, since the Korean paper has high formability, it is possible to easily form the diaphragm in a hemispherical shape. As a result, it is possible to radially and uniformly spread the sound by a simple structure.
摘要翻译：本发明涉及一种具有固定电极和隔膜的静电扬声器，该固定电极和隔膜与固定电极以预定的间隙布置并具有多个通气孔。通风隔膜减少由固定电极和隔膜之间的接地效应引起的空气阻力，并增加扬声器输出的声压。结果，通风隔膜使得可以在整个频率范围内获得均匀的频率再现特性。特别地，当隔膜由韩国纸制成时，由于韩国纸的透气特性和由于浪涌输入信号导致的空气阻力，可以有效地减少固定电极和隔膜之间发生的地面效应，同时满足现有隔膜的物理特性。此外，由于韩国纸具有高成形性，因此可以容易地将隔膜形成为半球形。结果，可以通过简单的结构使声音径向均匀地展开。

摘要： There is provided a back light unit having a light guide buffer plate. The back light unit having a light guide buffer plate includes a light source for generating the light when a power source is applied; a light guide panel whose light-receiving vertical surface that the light emitted from the light source enters is provided with a first prism pattern and whose bottom surface is provided with a refraction pattern, thereby converting the incident light from the light-receiving vertical surface into a surface light source; a reflection unit disposed in a bottom surface of the light guide panel to reflect light toward the light guide panel; and a buffer disposed between the light source and the light guide panel and whose light-emitting vertical surface corresponding to the light-receiving vertical surface of the light guide panel is provided with a second prism pattern. The back light unit can be useful to improve visibility, a mixing property and uniformity by basically removing a poor-visibility zone, which is formed in an end of the light guide panel, without any changes in the structure of the light guide panel.

摘要： A light guide plate of an LED backlight unit is disclosed. The light guide plate comprises a pair of wide planes facing each other, and a narrow plane formed between the pair of wide planes and constituting a thickness of the light guide plate. The narrow plane has an incident plane formed on a section of the narrow plane facing the LED light source, and one of the wide planes constitutes an exiting plane from which light entered from the LED light source exits. The incident plane has a plurality of elliptic cylinder-shaped grooves carved into the incident plane in a thickness direction of the light guide plate. As such, the elliptic cylinder-shaped grooves are carved into the incident plane of the light guide plate in the thickness direction, widening an incidence angle of which light can be transmitted therethrough.

摘要： A lens includes a convex surface formed in an outer surface thereof facing away from a light source to uniformly distribute light emitted from the light source; a concave surface concaved inward from an inner region of the convex surface, around an optical axis; and a convex portion convexed outward from a central region of the concave surface, which the optical axis intersects, in order to enhance quantity of light around the optical axis. The lens refracts light beams falling onto the respective areas thereof at different angles, thereby producing a uniform light distribution within a specific lighting range, but does not create a dark area around an optical axis.

摘要： The invention provides an LED package and a backlight device incorporating the LED lens. The LED package has a bottom surface and a light exiting surface cylindrically extended around a central axis of the package from the bottom surface. Also, a reflecting surface is positioned on an opposite side of the bottom surface and symmetrical around the central axis such that light incident from the bottom surface is reflected toward the light exiting surface. Further, a scattering area is formed on the reflecting surface. According to the invention, by applying scattering materials on the reflecting surface of the LED package, a reflecting paper does not need to be attached, thereby simplifying a process and reducing the manufacture time and cost.
