FIG. 4 is a schematic diagram of the optical engine 100 of the monolithic liquid crystal projector shown in FIG. 1; for convenience of explanation, only matters related to the embodiments of the present utility model are shown.

As shown in connection with fig. 4, the bare engine 100 has a mounting surface m1 and two side surfaces m2 located on opposite sides of the mounting surface m 1. The mounting surface m1 is provided with a first mounting portion p1, and the opposite sides of the two side surfaces m2 are respectively provided with a second mounting portion p2. That is, the first mounting portion p1 and the two second mounting portions p2 are located on three different surfaces, respectively. The two side surfaces m2 are arranged substantially opposite in the first direction F1. The two side surfaces m2 may be parallel to each other or may be inclined with respect to each other. For example, fig. 4 illustrates a case where two side surfaces m2 are not perpendicular to the first direction F1 and are disposed at an angle, respectively. The number of the first mounting portions p1 provided on the mounting surface m1 may be one or a plurality. The number of the second attachment portions p2 provided on the side surface m2 may be one or a plurality. The second mounting portions p2 on the two side surfaces m2 may or may not correspond in the first direction F1. Fig. 4 illustrates a case where two first mounting portions p1 are provided on the mounting surface m1, one second mounting portion p2 is provided on each side surface m2, and the two second mounting portions p2 are disposed opposite to each other in the first direction F1.

FIG. 5 shows a schematic diagram of a sound box 200 in the monolithic liquid crystal projector shown in FIG. 1; for convenience of explanation, only matters related to the embodiments of the present utility model are shown.

Referring to fig. 5, the speaker 200 is provided with a first engaging portion c1 and a second engaging portion c2. The first fitting portion c1 is fitted to the first mounting portion p 1. The second fitting portions c2 are fitted with the second mounting portions p2 one by one. It will be understood that "one-to-one fitting" means that the number of the second fitting portions c2 and the second mounting portions p2 are the same and correspond in position, respectively. That is, the second mounting portion p2 on each side surface m2 has a second fitting portion c2 corresponding thereto. Since the two side surfaces m2 are disposed opposite to each other along the first direction F1, the second engaging portions c2 are disposed on both sides of the speaker box 200 along the second direction F2. Similarly, the first engaging portions c1 and the first mounting portions p1 are also engaged one by one, which is not described herein.

When the first engaging portion c1 is attached to the first attaching portion p1 and the second engaging portion c2 is attached to the second attaching portion p2, the speaker 200 and the optical device 100 are fixed to each other. Since the two side surfaces m2 are located on both sides of the mounting surface m1 along the second direction F2, that is, corresponding mounting portions are provided on three surfaces, the speaker 200 can be assembled with the light engine 100 on three surfaces of the light engine 100. Compared with the manner of assembling and fixing the sound box 200 to the optical engine 100 along a certain direction, the assembly manner adopted in the embodiment of the utility model can fix the sound box 200 at least in two directions (the third direction F3 and the first direction F1 illustrated in fig. 2), and the fixing on three surfaces can form a more stable fixing support, thereby improving the assembly reliability of the sound box 200. In addition, in the assembly mode provided in the embodiment of the utility model, the sound box 200 and the optical machine 100 do not need to be connected by using an adapter, so that the whole structure is simpler and easier to assemble.

Accordingly, the single-piece liquid crystal projector further includes a first fastener (not shown in the drawings). The first fastener is threadably coupled with the first mounting portion p1 to securely couple the first mounting portion p1 and the first mating portion c1. That is, after the first mounting portion p1 is inserted into the first fitting hole k1, the first fastener is then fitted to the first mounting portion p1, and the first mounting portion p1 and the first fitting portion c1 are fastened. In some embodiments, the threads of the first mounting portion p1 are disposed on the outer surface of the first mounting portion p1, the first fastener may be a nut, and the first fastener may be screwed out of the first mounting portion p1 and abutted against the first mating portion c1. In other embodiments, as shown in fig. 4, a first fastening hole (not labeled in the drawing) is provided on the first mounting portion p1 along the longitudinal direction thereof, the inner wall of the first fastening hole is provided with threads, the first fastening member may be a screw, and the first fastening member may be screwed into the first fastening hole and abuts against the first mating portion c1.
