Abstract: How to wire ceiling speakers? How to arrange ceiling speakers? As we all know, ceiling speakers are often used in background music and broadcast systems in exhibitions, squares, restaurants, schools, etc., and are very popular in these places. Some families who have the conditions will also use it. Let’s introduce the installation method of ceiling speakers. Let’s take a look! How to install ceiling speakers, how to wire ceiling speakers, how to arrange ceiling speakers
How to install ceiling speakers
1. Installation of ceiling speakers - openings
1. Ceiling speakers can be divided into many types. The installation types are different in different places, and the installation methods are also different. Here we will first talk about the installation of home-style ceiling speakers. First of all, holes must be drilled to avoid damaging the ceiling, especially the ceiling with gypsum ceiling. A special hole opener is usually used.
2. The diameter of the opening should be according to the opening size specified for each ceiling speaker, but in actual construction, it can be slightly larger, so that it is easier to install and take out, especially for gypsum ceilings and ceiling speakers. If it is very tight, it will easily damage the gypsum board when it is removed.
2. Ceiling Speaker Installation - How to Wire Ceiling Speakers
1. The wiring layout of the ceiling speaker in the living room is best done together with the electrician’s wiring. Since the speaker wire is weak current, it cannot It is too close to the electrician's strong electricity (AC220 volts). If there is a PVC pipe, the distance is 20cm. These are all to avoid interference factors. However, the general wiring route should still try to follow the weak current route arranged by the electrician or Strong electricity to avoid clutter, and electricians generally leave access openings for wiring. The speaker wires should be distinguished from other lines so that they can be clearly distinguished during future maintenance.
2. The PVC pipe of the speaker line can be fixed on the ceiling suspension rod. The position of the speaker point and the position of various other lights, the position of the fire sprinkler head, and the air conditioner outlet should also be considered during the actual construction process. As for the air vents and the shape of the ceiling cap, if the speaker is installed in the same position as the lamp, or is designed at the air outlet of the air conditioner, it will affect the appearance. Those with higher requirements will pay attention to these, so they must also be taken into consideration.
3. The speaker wires are threaded through PVC. The PVC pipes are bent using springs to ensure that the wires in each pipe can twitch freely from the junction box, which also facilitates future maintenance, threading, and replacement. Usually electricians wait for painters to finish painting before installing various lights, which also avoids a lot of trouble.
3. Ceiling speaker installation - system debugging
The last thing to note is that the circuit must be checked before the system is turned on (after the circuit is laid out, it should also be checked before sealing the ceiling) line once).
How to arrange ceiling speakers
1. Centralized arrangement: The speakers are arranged centrally on both sides of the stage.
Advantages: convenient and practical, simple connection, less wires, accurate sound direction, and natural sound amplification.
Disadvantages: Easy to cause howling, and the microphone volume cannot be turned up very high.
Application scope: indoor theatrical performances, small dance halls, clubs, and multi-functional halls.
2. Distributed arrangement:
Use a decentralized method to install several ceiling speakers on the ceiling, or install several speakers on walls, behind seats, etc. . Notice! Speakers should be chosen with sharper directivity and their distribution range should be limited. When using ceiling speakers, it is better to have a lower ceiling.
Advantages: Improved direct sound ratio, even sound pressure distribution, and less likely to cause howling.
Disadvantages: Poor sense of direction.
Scope of application: voice playback, hall sound reinforcement, square sound reinforcement, playground sound reinforcement, multi-functional hall language sound reinforcement.
3. Centralized to decentralized layout:
Centralized as the main method and decentralized as the supplement. Music, theaters, etc. should use centralized playback for accurate sound, and distributed playback for speech amplification. Advantages: It combines the advantages of centralized and decentralized systems.
Disadvantages: The system is complex and the cost is high.
Application scope: Suitable for occasions.
4. Line array:
Line array speakers are designed for large-scale outdoor performances. Recently, there is a small product suitable for indoors. It is characterized by sharp directivity, the vertical radiation angle of each speaker is only 10 to 30 degrees, and the speaker angle can be accurately adjusted, with attenuation as small as 3dB per distance. It is suitable
for large conference multi-function halls with higher requirements.
In short, ceiling speakers are a widely used speaker style. They not only increase the volume, save space, but also decorate the environment. They serve multiple purposes.
