请教各位BASSBOX高手,单体参数中的Le值是选LMS测试值还是用DC测出来的静态值?

模拟网络中的(第二张图)Rx与Rg如何输入数值?以及类比线路中各代号的含义。

拜谢啦~~~~~~~~~

Include Ext. Resistance External resistance can have a dramatic effect on the response of a speaker design. This option allows you to include these effects in the design. When they are included, a “net” value for Qes, BL and Qts will be displayed in the Parameters tab. They show how the external resistance affects these parameters. Note: The “Include Ext. Resistance” checkbox will be disabled when Rx and Rg are zero.

Rx The series resistance of the speaker cables and terminals. It does not include the resistance of the crossover network.

Rg The source resistance of the amplifier. This is usually very low with most modern amplifiers. If the driver’s impedance (Z) is known, DF is calculated when Rg is entered.

DF The damping factor of the amplifier. If the driver’s impedance (Z) is known, Rg is calculated when DF is entered.

Include Ext. Network The effects of an external passive network can be included in the design. This enables the graphs to show the total system response with a passive crossover network, impedance equalization circuit and/or L-pad. The inclusion of the external network response in the graphs can also be controlled with a checkbox in the Graph Properties window and directly from the graph window by right-clicking on the graph and using the popup menu.

The circuit diagram above shows the position of each component in the circuit. The crossover network section can accommodate a 1st-4th order high-pass, band-pass or low-pass filter.

Open X•over File BassBox Pro is not a circuit designer—values for the network components cannot be calculated for you. However, our companion program X•over Pro is a filter designer and the “Open X•over File” button allows you to import a filter or network design from it. Clicking this button will open a dialog box to prompt you to select an X•over Pro design file. These files end in the file name extension “xo3”. Note: If it is installed, X•over Pro can be launched from the Tools menu of the BassBox Pro main window.

Cs1, Cs2, Cp1, Cp2 These are the series and parallel capacitors in a passive crossover network or filter. Units: mF, µF and pF. (Click on the units label to change units.)

ESR The equivalent series resistance is required for all capacitors in the crossover network or filter. The ESR is not required for the impedance equalization circuit. Units: ohms.

Lp1, Lp2, Ls1, Ls2 These are the parallel and series inductors or coils in a passive crossover network or filter. Units: mH.

DCR The DC resistance is required for all inductors in the crossover network or filter. The DCR is not required for the impedance equalization circuit. Units: ohms.

Rp1, Rp2 The series (Rp1) and parallel (Rp2) resistors of an L-pad. Units: ohms.

Req, Ce, Rm, Lm, Cm, Ra, La, Ca The components of an impedance equalization circuit. Such circuits are used to make the impedance of the driver appear “flat” to the crossover network so it can function properly. The impedance equalization network included with BassBox Pro can accommodate a wide variety of designs and our X•over Pro program can design them. Req and Ce are used to help equalize the reactance of the voice coil. Rm, Lm and Cm are used to help equalize the mechanical resonance of the system. Ra, La and Ca are used to help equalize the acoustic resonance of the system.

自己多摸摸就用一些简单的操作了.

看图示就可以明白嘛!Rx应该是连接线的电阻;Rg应该是放大器(功放)的内阻嘛!下面是阻尼系数嘛。

想不到沉浸多年的贴被顶出来了,谢楼上的~~~~~~

还有好多不太熟悉,可现在不做箱子了,有时间还是要多操练操练.

枪要常擦才亮不是~~~~~~
