Abstract:
A speaker unit for a projector includes a first speaker, a fixing portion and a second speaker. Either the first speaker or the second speaker has a central hole to hold the vertical post of a projector. Two holes that are diagonally opposing each other are provided in the inner wall of the central hole. The two holes of the fixing portion may align with the two holes of the first speaker and fasteners may be used to fixedly connect the first speaker with the vertical post. A connective portion is provided on either of the two vertical walls of the first speaker and a connective portion is provided on either of the two vertical walls of the second speaker. Therefore, the second speaker may be connected with the first speaker by these connective portions.
Abstract:
A photoelectric converting device which includes a substrate layer and an active layer is proposed. The active layer, which is disposed over the substrate layer, has a light receiving surface with a textured structure. The textured structure includes multiple indented units and each of the indented units includes three planes, which form an indentation tip at the intersection point between the three planes. The three planes are perpendicular or about perpendicular to each other.
Abstract:
The present invention provides an optical head with a single or multiple sub-wavelength light beams, which can be used in arenas such as photolithography, optical storage, optical microscopy, to name a few. The present invention includes a transparent substrate, a thin film, and a surface structure with sub-wavelength surface profile. The incident light transmits through the transparent substrate, forms a surface plasma wave along the sub-wavelength aperture located within the thin film, and finally re-emits through spatial coupling with the sub-wavelength profile of the surface structure. As the coupled re-emitting light beam or light beams can maintain the waist less than that of the diffraction limit for a few micrometers out of the surface with sub-wavelength profile in many cases, this invention can have applications ranging from micro or nano manufacturing, metrology, and manipulation by using light beams with waist smaller than the diffraction limit.

Abstract:
A transparent speaker is suitable for being disposed on a display panel. The transparent speaker includes a transparent membrane, a transparent electrode plate, and spacers. Each transparent electrode plate has a plurality of openings. The display panel includes a plurality of pixels. The pixels emit optical signals. A Moire spatial period of the optical signals is less than 600 μm after the optical signals pass through the transparent speaker. When the transparent speaker is disposed on the display panel, a user is able to watch an image on the display panel through the transparent speaker without being interfered by a Moire.
Abstract:
A head multi-directional audio device comprises: a head-wear member, which has two broadcasting devices, one buffer structure and two folding portions, the two broadcasting devices are with two sounding portions at the two external sides thereof, the two broadcasting devices are extended toward the right hand side and left hand side of the head-wear member individually, wherein the folding portion lets the broadcasting device, extended from the head-wear member, be bent inwardly; and two shelters, each has four braces that are to support the shelter on the two sounding portions, at least one sound exit is among the four braces on the each sounding portion, so that the sound from the sounding portion can be broadcasted by the sound exit.
