Chinese-English Translation:

音响中的音频线有两种:一种是信号线,是从音频输出的设备,比如手机、CD机、MP3的音乐输出信号的设备连接到功放之间的连接线;另一种是音箱线,是指功放输出连接喇叭的连接线,一般这种线比较粗,芯数比较多,因为要承载大电流的。

There are two kinds of audio lines in audio: one is the signal line, which connects the audio output equipment, such as the mobile phone, CD player, MP3 music output signal equipment to the connection line between power amplifiers; the other is the speaker line, which refers to the connection line between the power amplifier output and the speaker. Generally, this kind of line is relatively thick and has many cores, because it needs to carry large current.

音响线又称为喇叭线,主要用于用于家庭影院中功放和主音箱及环绕音箱的连接,也就是用于连接功放与音箱。相比视频线和音频线,它的流通电流信号比较大,由于信号幅度大,音响线往往是没有屏蔽层。对于这种线材,关键是要降低其电阻,因为现代功放的输出电阻很低,所以对音箱线的要求也随之增高,如选用截面积大的或多股绞合线。

The sound line, also known as the speaker line, is mainly used for the connection of the power amplifier, the main speaker and the surround speaker in the home theater, that is, for the connection of the power amplifier and the speaker. Compared with video line and audio line, its current signal is larger. Because of the large signal amplitude, the audio line often has no shielding layer. For this kind of wire, the key is to reduce its resistance, because the output resistance of the modern power amplifier is very low, so the requirements for the speaker wire are also increased, such as choosing the wire with large cross-sectional area or stranded wires.

音响线直接通过功率信号,因为通过电流大,通常线的铜芯会比较粗,为了保证高频通过和减小电阻衰减,大多是镀银、镀金或者无氧铜线。音响线,一般有分镀铜音响线和无氧铜音响线。

The audio line directly passes through the power signal. Because of the large passing current, the copper core of the line is usually relatively thick. In order to ensure the high-frequency passing and reduce the resistance attenuation, most of them are silver-plated, gold-plated or oxygen-free copper wire. Sound line, generally there are copper-plated sound line and oxygen-free copper sound line.

一般无氧铜为正极,镀锡铜为负极。双层外皮颜色为红色,两边都是黄铜色,无氧铜芯,正极那一边是有做一条红色线作为标记的。音响线由相应的铜芯根数组成,一般铜芯支数越多效果越好,价格当然也越高,不过如果是家庭用线或者普通音箱用线的话,其实选用 200 支到 300 支就够用了。

Generally, oxygen-free copper is the positive electrode and tinned copper is the negative electrode. The double skin color is red, both sides are copper, oxygen free copper core, and the positive side is marked with a red line. The sound line is composed of the corresponding number of copper cores. Generally, the more copper cores, the better the effect, and the higher the price. However, if it’s family line or ordinary speaker line, 200 to 300 will be enough.

音频线是用来传输电声信号或者数据的线,通过小电流小功率的信号, 阻抗高,容易受干扰,所以一般都是屏蔽线,线径一般是比较细的。音频线的种类可以分为两个大类,音频电信号缆”和“音频光信号缆。在市面上常用的是音频电信号缆。一般的规格有:3.5mm 公对公音频延长线、3.5mm 公对母音频延长线、双莲花头音频线等。

Audio line is used to transmit electroacoustic signal or data. It has high impedance and is easy to be interfered by small current and small power signal, so it is generally shielded wire, and the wire diameter is generally thin. The types of audio cable can be divided into two categories: audio electric signal cable and audio optical signal cable. The audio signal cable is commonly used in the market. General specifications include: 3.5mm male to female audio extension cable, 3.5mm male to female audio extension cable, double lotus head audio cable, etc.

2.音响线、音频线的区别

2. Difference between audio line and audio line

音响线主要传输的是功率信号,所以要求音箱线要具有优秀的导电性能和高质量的传送能力。目前来说,无氧铜音响线,也就是所谓的金银线,比较主流,电阻较小。音响金银线通常是没有屏蔽层的,因为其中流通的电流信号大于音频线和视频线,信号的幅度很大。最重要的是要减低线的电阻,功放输去时的阻抗是很低的。

The sound line mainly transmits the power signal, so it is required that the sound box line should have excellent conductivity and high-quality transmission ability. At present, the oxygen free copper sound wire, also known as the gold and silver wire, is relatively mainstream with small resistance. The audio gold and silver wire usually has no shielding layer, because the current signal in it is larger than the audio wire and video wire, and the signal amplitude is very large. The most important thing is to reduce the resistance of the line. The resistance of the power amplifier when it is transmitted is very low.

音频线通过的是小功率小电流的信号,而且阻抗高,容易受干扰,所以一般是屏蔽线,线也比较细。音频线通常是有屏蔽层的,但音响线往往是没有屏蔽层,关键是要减低电阻。在深蓝大道音响线中,比较贵的是无氧铜音箱专用线,主要特点是导电性能好,电阻率低。

The audio line passes through the signal of small power and small current, and it has high impedance and is easy to be interfered, so it is generally shielded wire, and the line is also relatively thin. The audio line usually has a shielding layer, but the audio line often does not have a shielding layer. The key is to reduce the resistance. Among the deep blue Avenue audio lines, the more expensive one is the special line for oxygen free copper speakers, which is characterized by good conductivity and low resistivity.

音频电信号缆可用于手机、CD 机、MP3 的音乐输出信号的设备连接到功放之间的连接线。音箱线主要应用于各型扬声器、PA 工程、家庭影院连接、公共空间广播系统。

The audio electric signal cable can be used to connect the equipment of music output signal of mobile phone, CD player and MP3 to the connecting line between power amplifiers. Speaker line is mainly used in various types of loudspeakers, PA engineering, home theater connection, public space broadcasting system.
