The equipment of the speaker system in the sound engineering has three ways of surface mounting, concealing and lifting. The mounted speaker system is directly installed in the visual hall of the audience hall; the concealed refers to the speaker system installed in the flat top or in the frame and wall. The lifting refers to the use of hooks, hanging poles or hanging baskets to hang the speaker system. On the ceiling and on the wall, there are two ways of hanging and hanging when lifting.
First, the speaker's key to the installation of the key 1 sound is not obstructed, can be directly shot to the audience, the sound energy loss is very small.
2 device, adjust the direction, can adjust the sound radiation direction of the speaker very intuitively at the scene, to ensure a more uniform direct sound in all areas of the audience.
3 should pay attention to safety.
4 Be careful not to let the speaker affect the overall appearance of the hall.
Second, the speaker concealed key 1 reserved device hole is necessary to meet people, in order to adjust the direction of the speaker system 2 installed in the ceiling of the speaker system has two ways.
One is that the speaker is placed in parallel with the ceiling. The speaker is placed directly on the ceiling, and the sound is directly from the ceiling to the corresponding auditorium. This method is usually applied to the sound system of the stadium, the low sound box system and the background speaker system.
The other is that the speaker is mounted in the anti-sound cover of the ceiling to prevent the sound energy from escaping in the flat top. The flat top of the reflector of the device should have a large area, and the exit of the anti-sound cover itself must also meet the large space according to the sound radiation of the speaker, so that the sound cover of the speaker is not affected. The acoustic enclosure is made of hardwood and is firmly fixed to the top grill to prevent resonance from occurring by the operation of the loudspeaker, damaging the sound quality of the reproduced sound.
3 The mask used for concealing needs to be transparent. The width of the decoration piece should be less than 1/10 of the diameter of the installed speaker cone. The aperture ratio of the piece should be greater than 75%. The decorative piece is best made into a wedge shape. Conducive to the transmission and spread of sound waves.
5 Concealed mode is conducive to the decoration effect of all halls, but if it is not handled well, some direct sound can be lost, and the installation is difficult, adjustment and maintenance are also very inconvenient.
Third, the speaker hoisting should pay attention to the two points one is that the hoisting position and the slanting point of view directly affect the sound field distribution of all halls, hoisting the point of view and the bunching area of ​​the main sound beam of the speaker;
Second, the degree of solidity of the hoisting is directly related to the safety inside the hall.
