Placement of center audio equipment: Center speaker is usually the main force of human voice, so its function can never be ignored. Generally speaking, it is best to put the center speaker in the visual center in front of the listening room, such as above the TV. However, due to the interaction between the speaker magnetic column and the TV magnetic field, as well as the vibration between the speaker and the TV shell, direct placement will affect the effect of audio equipment, so the center speaker is best placed on a separate bracket slightly higher than the TV, and the position should not be too high. For screens such as projection screens, there are no restrictions before and after. Placement of left and right audio equipment: The positions of the left and right main speakers of household audio need to be symmetrically arranged on both sides of the center speaker, and the distance from the center speaker should not be too close. It is best to have an arc around the listening position. The suitable height position is that the central axis of the tweeter in the main speaker is 0.3m above and below the center speaker. If you put it directly on the ground or hang the left and right audio equipment on the ceiling, the midrange position will deviate from the best angle, which will make people feel the sound field is chaotic. If you use a bookshelf speaker, it is best to install a bracket instead of a speaker to ensure that the height of the speaker is moderate. Placement of surround sound equipment: surround speaker's role in home audio equipment is mainly to create the spread and breadth of sound field, so it is more appropriate to place it at the top half a meter. The presented sound field needs to be adjusted according to personal feelings. Because the directivity of bass is very weak, there is generally no rigid requirement for the placement of bass units.
The installation height of professional speakers is 0.5 ~ 0.8 meters according to the height of listeners' ears.
If the surround speaker is placed on the bracket, it is best to choose the position where the speaker line goes out of the wall above the wall root and skirting line.
If you are going to hang the surround speaker on the wall, the height of the speaker line out of the wall is generally 1.4~ 1.6 meters. Use a blank panel with a hole in the middle (if the audio cable is directly connected to the speaker) or a speaker-specific panel (if the speaker is inserted through the audio connector).
If you use a corner sofa, if you use a bracket, you can only put it outside the corner. If it is not a corner sofa, but it is usually enjoyed by young couples, it can be close to the main sofa. But it won't make much difference.
Installation mode
1. First of all, the installation of surround sound is the same as the installation of lamps. If you don't want to affect the decoration of the whole space, you'd better arrange the installation position of surround sound first, and then embed the wires, that is, bury the surround speaker wires in the ground and gypsum line in advance.
2. Generally, the phoneme is 5. 1, and two main speakers are arranged in front, and the voices are clearly surrounded for watching movies and placed on both sides of the sofa.
3. The bracket can be rotated inward by 45 degrees around the installation, and the effect will be slightly better. Hanging on the wall can only go forward. Leave a hole at the top and bottom at the same time, and the line will go out from the top. If the bracket is used in the future, just pull out the wire from the opening reserved below.
How high is the home speaker?
The best placement scheme of sound box. There are three conditions for the best placement of speakers: the distance from the back wall is not less than 20cm, the distance from the side wall is not less than 20cm, and the third is the height condition. The tweeter of the speaker is flush with the listener's ear, or the height of the speaker's feet is 1-2 times the diameter of the woofer.
What is the installation height of the speakers in the lecture hall?
The speaker installation height of the lecture hall is about 1.5 to 2 meters.
According to the different sound field layout, the lecture hall system is divided into round table meeting and non-voting meeting. The main components are sound building system, sound reinforcement system, conference system, lighting system, video system, conference simultaneous interpretation and tracking system and intelligent central control system.
Due to the particularity of its function, the lecture hall must have good language clarity. Besides good audio equipment, it must also be designed acoustically to provide a good acoustic environment.
Basic introduction of sound:
Audio equipment consists of sound source music playing equipment, pickup equipment, namely microphone, control equipment analog or digital mixer, and audio processor. It used to be peripheral equipment such as effector, equalizer, voltage limiter, frequency divider, signal distributor, delay, etc. Now there are digital system controllers, power amplifiers and sound boxes that integrate the above functions.
The development history of audio technology can be divided into five stages: vacuum triode, electron tube, transistor, integrated circuit and field effect tube. The acoustic characteristics of audio equipment should not only meet the requirements of national standards for acoustic characteristics, but also meet the requirements of subjective hearing, because the acoustic characteristics can not fully reflect the actual acoustic effect, and the sound quality is ultimately determined by people's subjective hearing.
In acoustic design, electroacoustic and architectural sound design should be well coordinated to meet the following subjective hearing requirements: appropriate loudness. Loudness is the feeling of actual listening intensity, which is directly related to the maximum sound pressure level index of the sound reinforcement system.
For playing, only when the loudness is enough can the sound effect be fully displayed. The output power of the system and the placement position of the sound box will directly determine the loudness state of the listening area is high fullness.
12 inch stereo installation height
1. The installation height of professional speakers can be extended by 0.5 ~ 0.8m according to the height of listeners' ears.
2. If the surround sound is placed on the bracket, it is best to select the outlet position of the sound line at the root of the wall and above the skirting line.
3. If you want to hang surround sound on the wall, the height of the sound line protruding from the wall is generally 1.4~ 1.6 meters. Use a blank panel with a hole in the middle (if the audio cable is directly connected to the speaker) or a speaker-specific panel (if the speaker is inserted through the audio connector).
4. If you use a corner sofa, if you use a bracket, you can only put it outside the corner. If it is not the corner sofa, but the favorite of young couples, you can get closer to the main sofa. But it won't have much impact.
