An image projection system has a single reflective light modulator (111), and includes at least one light source (101,103,105). A combiner (107) may be used to combine the light emitted from multiple light sources. A field lens (110) may be placed in conjunction with the reflective light modulator. An optical system (108) may be used to uniformly distribute the light projected on the reflective light modulator and so to be independent of the light intensity distribution of the light source, and/or to change the shape of the light to be projected onto the reflective light modulator. The image projection system may be mounted in a mechanical structure (701,801) having a loudspeaker driver unit (802) installed directly on a surface such that the acoustical and optical waves share the same space. The mechanical structure may be composed of a heat conducting device attached to a heat generating element. |
