First, read the English article below.

Perhaps this is a couch, love seat or your favorite chair. The ideal placement is halfway between the two side walls and at least a couple of feet back from the exact center of the room. Avoid placing the target seat all the way up against the back wall of the room. Flat surfaces such as walls tend to shatter the sound a little before reflecting it, so you will get a better effect if you leave a buffer between the back wall and the target. This will help to rectify the distortion of reflected sound. They should be at least one foot out from the back wall and at least two feet away from the side wall for optimal sound quality. This means the distance should be the same between all three parts, creating a perfect equilateral triangle. 

Now, please write a short abstract for it in Chinese. Abstract:
