1. We advocate to make plans according to the site, only according to the drawings without observing the actual site, and it is generally difficult to achieve the best results in the plan of ceiling speaker selection and speaker point layout. The installation distance between the ceiling loudspeaker is for reference in the industry: the distance between each two speakers is twice the distance from the speakers to the ground. Usually, this installation method can meet the requirements of uniform playing sound throughout the venue. It is also a waste to install more horn speakers. However, it is necessary to configure the speaker power and the PA loudspeaker point layout according to the different venue environment. It is necessary to consider the location of the area where the people (listeners) in the venue are often located Whether the listeners often move, or are in a fixed position, whether they are standing or sitting, and the size of the background noise of the whole venue environment. The installation and layout of loudspeaker horn in hotels, rooms, halls, corridors, restaurants, offices, supermarkets, exhibition halls and other venues and in each local area are different. If you want to do a good job, there is no standard to copy. Just like a good hairdresser, you need to design your hairstyle according to everyone's face type, head type, skin color, hair quality, even personality and occupation. In this regard, Even the simplest ceiling speaker design and installation is not purely a technical problem. A good background music project is a combination of experience, technology and art.
2. With regard to the selection of speakers and other equipment, many companies will provide you with three options: the poor, the medium, the best, or the cheapest, the average, the most expensive, or some people say: domestic, joint venture, and kou. Provide customers with three levels of solutions. Many customers are also very satisfied with the choice of three grades. This can be said to provide a very good service, but from our point of view, we think this is irresponsible behavior, this is only a commercial behavior, and it is irresponsible behavior. Let me give you another example: if you go to the store to have your hair done, for example, a perm, the hairdresser in the store will give you something like a menu, which is also a choice of three grades: cheap, ordinary, good, or 180 yuan, 280 yuan, 380 yuan, or ordinary potions, general potions, and imported potions. There are three options for perming a head, but for you, you can't figure out the difference between a 180 yuan head and a 280 yuan head. If you ask him, he will certainly tell you that the 180 yuan head only uses ordinary potions, while the 280 yuan head will use good potions. The good potions will have good effects, and the damage to the hair will be small, so you will certainly choose according to your actual situation. But the hairstylist will never tell you that the damage of perm to hair is certain, the size of the damage and the effect of perm have nothing to do with the 180, 280 and 380 potions you choose, and the most important thing is the perm: in short, everyone's hair quality is different, according to different hair quality, how much potions are used, how long they are washed, and how long they are permed, And the hairstylist's hand hair skills and so on are the key factors that determine the quality of your hair style and the damage to your hair! Have you ever experienced that you can get a beautiful shape with 180 yuan, or your hair is burnt out with 380 yuan?
Of course, any kind of product will have several grades at different prices, including good quality, poor quality and even fake and inferior products. I don't mean that there is good technology. Even if we use speakers with poor quality, we can play beautiful music. That's impossible. What I say is that we need to tailor the background music scheme. We need to communicate with customers, understand the situation and functions of the scene, and then provide the most reasonable set of playback based on these, instead of only providing three different price schemes for customers to choose, The customer doesn't know much about your technology. Besides, he doesn't know what the effect of your expensive speakers and ordinary speakers is. It is often the case that the customer chooses a cheap solution, but after the installation of the whole project, the effect is very poor, and even the sound of electric current in the speaker can be heard, and the treatment advice is: the cheap thing is like this, only this effect can be achieved. These are irresponsible behaviors.
2. Installation process
It mainly refers to the wiring and installation process in coordination with the decoration progress.
1. It is better to lay the speaker line together with the electrician's wiring, but the speaker line is weak current, so it should not be too close to the electrician's strong current (AC220V). If the PVC pipe is worn, the distance of 20cm is enough. This should be done due to installation and interference factors, but the overall wiring route should follow the strong current or weak current route arranged by the electrician as much as possible, so it is not disorderly and convenient for future maintenance, Because electricians usually leave access holes for wiring, the horn wire should be different from other lines. Don't forget which one is the horn wire in the future maintenance. The PVC pipe of the horn line can be fixed on the ceiling suspender. Another thing that needs to be coordinated with the electrician is that the location of the horn point also needs to consider the location of various lights, the location of the fire sprinkler, the air outlet of the air conditioner, and the shape of the ceiling cover. If your horn is installed at the same location as the lamp, or is designed at the air outlet of the air conditioner, it is not good, and it also affects the aesthetics.
The horn wire is threaded through PVC pipe. We require that the PVC pipe not use elbow, but use spring bending to ensure that the wire inside each pipe can be pulled freely from the junction box, mainly to ensure future maintenance, wire replacement and threading.
2. Precautions for horn hole opening: use special hole opener, and do not damage the ceiling, especially the ceiling of gypsum ceiling.
The opening diameter is based on the specified opening size of each speaker. In actual construction, it can be slightly larger, so that it is easier to install and take out, especially the gypsum ceiling. If the speaker is installed tightly, it is easy to damage the gypsum board when it is taken down.
Hole opening of ceiling horn: be careful not to open it on the vertical and horizontal keel!
3. It is better to install the ceiling horn carefully after the special workers finish painting. Usually electricians also install various lights at this time.
In short, these processes need to be well coordinated with other types of work on the site. We should not only consider our own progress, but also communicate and learn from them frequently.
4. System commissioning
It should be noted that the circuit must be checked before the system starts up and runs. Of course, the circuit should be checked after the circuit is arranged (ceiling sealing).
