Villa home theater design needs to be considered3Points
(1) Choice of room
Sound travels in the room When , some frequencies are often excited to generate resonance phenomena to form “standing waves”. This resonance greatly affects the studio effect. The distribution of “standing waves” is related to the geometry of the room. In order to avoid the “standing wave” phenomenon, it is best to choose a rectangular one for the audio-visual room. Also choose the proper proportions and shapes. Of course, if the room size is a foregone conclusion and it is difficult to change, the method of increasing the room interface damping can be adopted to reduce the resonance intensity.
(2) Selection of home theater equipment
1, Stereo
If you simply consider the cinema, you don’t need to be too demanding on the sound style of the speakers, but the minimum requirements are: etc. The power or power is preferably more than 100 watts, and the frequency response is the full frequency range, that is, the low frequency band must be below 100 Hz, and the high frequency band must be above 20,000 Hz. The three front speakers can’t make do with it! But we can’t just watch movies without listening to music, so the playback effect of two-channel music also needs proper consideration. In addition, we must also consider the perfect combination of speakers and your home decoration, so that you can not only enjoy wonderful movies, but also make your home look neat and unified, without affecting your decoration style – embedded speakers are just It can do this, so that you can only hear its sound, but not its shape.
2, projector
According to the nature of the displayed source, projectors can be mainly divided into two categories: video type (home and professional) and commercial multimedia type.
The home video projector is optimized for video, which is characterized by brightness between 600 and 1200 lumens, high contrast and clear picture quality. The projected screen aspect ratio is mostly 16:9, and a variety of video ports are available for playing HD movies, HDTV, entertainment and games.
The commercial multimedia projector mainly displays the signal output by the computer, which is used for business presentations, office work and daily teaching. The brightness has different choices according to the use environment, and the aspect ratio of the projection screen is 4:3 , full-featured, can demonstrate images, texts and videos, the image quality is poor, not suitable for home theater.
(3) Equipment debugging and system adjustment
When all equipment In place, after the installation is complete, the commissioning work begins. It is not enough to have sound and picture, you need to carefully understand the function of each piece of equipment. If TVs and projectors want to have a good picture, they must use software to test and adjust. For example, “HIVICAST” is a relatively easy-to-use debugging software. The sound is more complicated. In addition to the correct installation according to the cinema standard, the position and angle of the center and surround should be adjusted repeatedly. There is also a subwoofer, which needs a little movement, a little trial, and sound absorption and diffusion processing. , there are tricks everywhere. Take your time and have fun. You know, if the plane does not go to the sky and the earthquake does not sink, it is not necessarily a problem of equipment.
