求翻译：第二个装置投影仪在外面，投影设置的符合缸的表面，于是当投影仪里的图片反射到缸面上，同时第一个缸里传出声音，两者完美结合。是什么意思？

The second device projector set up in line with the cylinder surface at the outside, projection, so when the projector picture reflection to the cylinder surface, while the first tank came the sound, both the perfect combination.

The first 2 units projector projector set up on the outside, the surface of the cylinder, and then when the projector is reflected in the picture on the cylinder surface, at the same time the first cylinder, the sound, both work together.

The second equipment projecting apparatus in outside, the projection establishment conform to the cylinder surface, therefore when in the projecting apparatus picture reflects to the cylinder surface on, simultaneously in the first cylinder spreads the sound, both unify perfectly.

Second installation projectors out there, the projection set that meets the surface of cylinder, so that when the projector's picture onto cylinder surfaces, while outgoing sound in the first cylinder, the perfect combination of the two.
