专业济南音响工程是汇集了多项学科知识的一项综合性工程。它包含了较高的技术含量，需要严格与周全的设计和音响设备的选型；需要合格的管线预埋，需要可靠的焊接技术，需要科学的调试检测手段等等。而相位的问题则是音响工程中所包含的一个很小部分，但是它有着举足轻重的作用。济南音响系统中的相位是很抽象的，涉及到很多相关的问题（如电路中相位，电源相位，音箱单元相位，话筒拾音相位等等）。
Ji'nan professional sound engineering is a collection of multiple disciplines knowledge a comprehensive engineering. It contains high technology content, need strict and comprehensive design and type selection of audio equipment; need to pre qualified buried pipeline, the need for reliable welding technology, need to debug a scientific means of detection and so on. While the phase problem is a very small fraction contained in sound engineering, but it plays an important role in. Phase sound system in Ji'nan is very abstract, involves many related issues (such as circuit phase, phase of the power supply unit phase, speakers, microphone phase etc.).
相位概念 声波的一个振动周期等于360度，在这一个振动周期中，一个振动点（或粒子）所达到的阶段用度来表示，如果是0度~180度与180度~360度的关系，也就是我们说的正值与负值的关系，它们的相位是相反的。
A vibration cycle phase concept acoustic wave is equal to 360 degrees in this one period of vibration, a vibration point (or particles) to represent the stage reached expenses, if the relationship is 0 degrees ~180 degrees and 180 degrees ~360 degrees, is positive and negative we say their relationship, phase the opposite.
1、在物理学中，济南音响相位的概念是反映交流信号任何时刻的状态的物理量。交流信号的大小和方向是随时间变化的。
1, in physics, the concept of Ji'nan sound phase is a physical quantity to reflect the state of the AC signal at any time. The size and direction of AC signal changes with time.
2、在音响系统中，济南音响 http://www.jnzqyx.com/ 相位是对声场中量感变化相对而言的，于是便有了同相与反相对音响系统的影响问题。两个频率相同的音频信号从功放输出，如果一个音箱的信号反相，那么这个相位的差叫做相位差，或者叫做相差。在物理学中，这两者的相位差正好等于180°，这种情况叫做反相位，或者叫做反相。
2, sound system, Ji'nan sound on the sound field in the amount of phase is the change of relative to character, so there is a problem affecting the in-phase and anti relatively sound system. The audio signal of two same frequency from the power output if the signal inverting a speaker, then the phase difference is called the phase difference, or the difference between. In physics, the phase difference between the two is exactly equal to the 180 degree, this situation is called reverse phase, or called reverse.
3、在声场环境中，济南音响相位是相对听音位置来说的，单个音箱时也可以说是相对它的中轴线来定义的。
3, in the acoustic environment, Ji'nan audio phase is relatively listening position for a single speaker, also can be said to be relative to its axis to define.
