The layout principles and methods of speakers

       First of all, we have a simple understanding of the layout principle of the speaker：
       In the sound technical knowledge about the speaker layout principle mainly refers to a few points:
       The first principle: the need to make the whole hall of sound field uniform
       The second principle: as much as possible to overcome strong feedback to improve the transmission gain
       Third principles: in the layout of the time as far as possible to do the simple line, easy to repair and adjust the coverage angle
       Fourth principles: the layout of the speaker needs to be consistent with the audio and visual direction, sound kind of natural
       Fifth principles: the speaker cover angle (4kHz, 8kHz as the axis of the 6dB) to cover all the audience
       The sixth principle: the sound of the loudspeaker is emitted, and it is more than the natural sound source 5~30ms
       Simple understanding of sound technical knowledge in the layout of the speakers in the principle of knowledge in the future we will then some simple look at the layout of several knowledge.
       The layout of the speakers should be centralized layout. When using this kind of arrangement, we should pay attention to two points:
       The first point: the need to set the stage and require the visual effect of the same
       Second point: by the construction, the shape limit is not inappropriate to disperse the layout
       In these two cases, we can use the centralized layout to arrange the speakers. Another way that is the scattered layout. In the following two cases we can use this arrangement.
       First: building hall high clear height, vertical long distance or hall could be separated into several parts using, it should not be used in centralized arrangement
       Second: Hall reverberation time is long, it is not the focus of the layout
       In addition to the above two kinds of speakers to see the layout of the way, there is a way in the audio technology, it is a mixed type. In the following ways we can use mixed mode:
       ①Balcony is too deep or set up theatre, should be part of the occluded auxiliary loudspeaker system arrangement
       ②For large or vertical distance of the building hall, in addition to focus on setting up the speaker system, the appropriate layout of auxiliary speaker system
       ③Each direction has the audience's audio-visual hall
       With this arrangement if we want to solve the problem of first and second control sound path difference and limit the level of that in need should be plus time delay measures to avoid the phenomenon of double sound.
       To sum up, we will be in the acoustic technology today to share with you about the layout principle and ways of several important issues.
