Common Installation Ways of Sound Box in Audio Engineering

There are three ways to install the speaker system in audio engineering: open installation, concealed installation and hoisting. Open installation refers to the sound box system directly installed in the auditorium visible place; implicit installation refers to the sound box system installed in the flat roof or in the frame, wall, hoisting refers to the use of hooks, hanging metal or hanging baskets to hang the sound box system on the ceiling, wall, hoisting can have two forms of hidden hanging and open hanging.


I. Main Points of Open Loading of Speakers
Sound is not blocked and can be directed to the auditorium with little loss of sound energy.

(2) Installing and adjusting the direction can intuitively adjust the sound radiation direction of the speaker on the spot to ensure that more uniform direct sound can be obtained in each area of the auditorium.

3. Full attention should be paid to safety.

4. Be careful not to let the speaker affect the overall shape of the hall.

2. Key Points of Undercover Loading of Speakers
(1) The reserved opening must be manned enough to adjust the direction of the speaker system.

There are two ways to deal with the sound box system installed in the roof.

One is that the speaker is placed parallel to the ceiling. The speaker is placed directly on the roof, and the sound is directed from the roof to the audience. This method is usually applicable to the venue sound supply system, the bass system and the scattered background speaker system of the gymnasium.

The other is that the speaker is enclosed in the echo hood of the roof so as to prevent the sound from escaping from the flat roof. There should be enough space in the flat roof space where the reflector is installed, and the outlet of the reflector itself must also have enough space according to the sound radiation angle of the speaker, so that the sound coverage of the speaker is not affected. The echo cover is made of hardwood and firmly fixed on the top grille to avoid resonance caused by the work of the loudspeaker and destroy the sound quality of the replay.

(3) The mask used in concealed costume must be sound-proof.

(4) The width of the decorative grille should be less than 1/10 of the diameter of the sound box and carton, and the opening rate of the grille should be more than 75%. The decorative grille should be made into a wedge, which is beneficial to the propagation and diffusion of sound wave.

(5) Concealed form is conducive to the decorative effect of the whole hall, but if not handled properly, some direct acoustic energy will be lost, and installation is more troublesome, adjustment and maintenance is also very inconvenient.

3. Two Points for Attention in Lifting Speakers
First, the hoisting position and inclination angle directly affect the sound field distribution of the whole hall, the hoisting angle and the cluster area of the main sound beam of the speaker.

Second, the firmness of hoisting is directly related to the safety of the hall.
