Woofers, mid-range speakers, and tweeters are all types of loudspeakers. Most often, all three types of speakers are mounted in a single enclosure, but you can also find each in discrete enclosures. Let’s take a closer look at how they work.

低音扬声器，中音扬声器和高音扬声器是所有类型的扬声器。 通常，所有三种类型的扬声器都安装在单个机箱中，但是您也可以在离散的机箱中找到它们。 让我们仔细看看它们是如何工作的。

Loudspeakers are a type of electrical transducer that converts an electrical audio signal into sound. The most widely used type of speaker today—the dynamic loudspeaker—was first built in the 1920’s. It uses a magnetic field to move a flexible diaphragm back and forth very quickly to produce sound waves that carry those sweet tunes right to our ears. That diaphragm is usually fabric, plastic, or paper, and is most often conical in shape, though some speaker makers use different designs.

扬声器是一种将电子音频信号转换为声音的电转换器。 当今使用最广泛的扬声器类型-动态扬声器-始建于1920年代。 它使用磁场使弹性膜片快速来回移动，产生声波，将那些甜美的声音传到我们的耳朵。 尽管某些扬声器制造商使用不同的设计，但该振膜通常是织物，塑料或纸制，并且通常是圆锥形的。

We categorize speakers by the range of sound they put out, as measured in Hz. Some speakers are considered full-range, since they attempt to put out all the frequencies they are sent. The trouble with that is that the size of these full range speakers typically limit how good they sound. Small full range speakers just can’t get enough of that bass, and larger ones tend to not do well with the higher frequencies.

我们根据扬声器发出的声音范围(以Hz为单位)对扬声器进行分类。 一些扬声器被认为是全频的，因为它们试图输出所有发送的频率。 麻烦的是，这些全频扬声器的尺寸通常会限制它们的音质。 小型全频扬声器无法获得足够的低音，而较大的扬声器往往无法在较高的频率上表现出色。

Other speakers are more specialized to different ranges. Woofers handle the lower range, mid-range speakers handle the middle range, and tweeters handle the highest range. Put these discrete speakers together, and you get a much fuller, more accurate sound reproduction than you get with a single full-range speaker.

其他扬声器更专门针对不同范围。 低音扬声器处理较低范围，中音扬声器处理中级范围，高音扬声器处理最高范围。 将这些分立扬声器放在一起，您将获得比单个全频扬声器更饱满，更准确的声音再现。

低音扬声器 (Woofers)

Woofers are made to handle the lower range of frequencies (sound waves) for a speaker system, and there are a few different types, depending on your needs. Although they are all built very similarly, there are some distinct differences between each type:

低音扬声器可以处理扬声器系统的较低频率范围(声波)，根据您的需要，可以有几种不同的类型。 尽管它们的构建非常相似，但是每种类型之间还是有一些明显的区别：

• Standard Woofer: A standard woofer produces frequencies from 20 Hz up to 2,000 Hz (2 kilohertz, or 2 kHz). The woofer is often characterized by its bassy sound which comes from the lower frequency sine wave. You’ll typically see standard woofers as part of higher-end speakers that contain either a woofer and tweeter (a setup known as a 2-way speaker) or a woofer, tweeter, and mid-range speaker (a setup known as a 3-way speaker).

  标准低音扬声器：标准低音扬声器的频率范围从20 Hz到2,000 Hz(2 kHz，或2 kHz)。 低音扬声器的特点通常是低频正弦波产生的低音。 您通常会看到标准低音扬声器是高端扬声器的一部分，其中包含低音扬声器和高音扬声器(称为2声道扬声器)或低音扬声器，高音扬声器和中音扬声器(称为3扬声器)。扬声器)。

• Subwoofer: Subwoofers are only capable of producing tones lower than 200 Hz in consumer systems. They are made up of one or more woofers, often mounted inside a wooden enclosure. Although the human ear is only able to pick up a frequency as low as 12 Hz, subwoofers working at lower frequencies can only be felt, if not heard. Subwoofers are the most common add-on to a consumer speaker setup. They are typically placed in their own, isolated enclosure and provide the low-level thump that you just can’t get with standard woofers.

  低音炮：低音炮只能在消费类系统中产生低于200 Hz的音调。 它们由一个或多个低音扬声器组成，通常安装在木制外壳中。 尽管人的耳朵只能拾取低至12 Hz的频率，但如果听不到，只能感觉到工作在较低频率的低音炮。 低音炮是消费者扬声器设置中最常见的附件。 它们通常放置在自己的隔离式外壳中，并提供标准低音扬声器无法提供的低级重击声。

• Midwoofer: Midwoofers land right in the middle of the ‘woofer’ range, coming in from 200 Hz -5 kHz. Having such a wide range of frequencies, this speaker will produce the best quality sound from 500 Hz-2kHz and start to deteriorate at either end of the spectrum.

  Midwoofer：Midwoofers土地的权利在“低音单元”范围的中间值，从200赫兹-5千赫进来。 该扬声器具有如此宽的频率范围，它将在500 Hz-2kHz的频率范围内产生最佳质量的声音，并在频谱的两端开始恶化。

• Rotary Woofer: A rotary woofer is a woofer-style loudspeaker that uses a coil’s motion to change the pitch of a set of fan blades, instead of using the cone shape. Since the pitch of the blades is changed by the audio amplifier, the power required is much less than that of a conventional subwoofer. They are also far superior at creating sounds well below 20 Hz, below the normal level of human hearing, able to produce frequencies down to 0 Hz by compressing the air in a sealed room.

  旋转低音扬声器：旋转低音扬声器是一种低音扬声器，它使用线圈的运动来改变一组风扇叶片的音高，而不是使用圆锥形状。 由于叶片的音高由音频放大器改变，因此所需的功率比传统的低音炮小得多。 它们在产生远低于20 Hz，低于人类正常听力水平的声音方面也非常出色，能够通过在密封室内压缩空气来产生低至0 Hz的频率。

In most consumer speaker setups, you’re likely to find a standard woofer as part of your main speakers and possibly an additional, but separate, subwoofer.

在大多数消费类扬声器设置中，您可能会在主扬声器中找到标准低音扬声器，并可能会找到一个额外的但独立的超低音扬声器。

中音扬声器 (Mid-Range Speakers)

Mid-range speakers are targeted to handle the ‘middle’ range of the spectrum, coming in between 500 Hz-4 kHz. This is probably the most important range of frequencies due to most audible sounds, such as musical instruments and the human voice, being produced here.

中音扬声器的目标是处理频谱的“中”范围，介于500 Hz-4 kHz之间。 由于此处产生了大多数可听见的声音(例如乐器和人的声音) ，因此这可能是最重要的频率范围。

Since the human ear is most sensitive to the mid-range frequency, the driver can remain at a lower power, while still providing good sound in terms of quality and volume. Because mid range speakers are unable to produce the extreme low or high spectrum, they often sound dull, or flat, and need the support of a woofer or tweeter to get the full level of sound.

由于人耳对中频最为敏感，因此驱动器可以保持较低的功率，同时在质量和音量方面仍可提供良好的声音。 由于中音扬声器无法产生极低的或高频谱，因此它们通常听起来暗淡或平坦，并且需要低音扬声器或高音扬声器的支持才能获得完整的声音。

You’ll find mid-range speakers used as part of a speaker that also includes a woofer and tweeter, and they’re also used in the center speakers often used with surround sound systems.

您会发现中频扬声器是扬声器的一部分，还包括低音扬声器和高音扬声器，它们也用在通常与环绕声系统一起使用的中置扬声器中。

高音扬声器 (Tweeters)

On the high end of the sound spectrum, we have tweeters, which get their name from the high tweet of birds. Tweeters typically cover the range of 2 kHz-20kHz, though some specialty tweeters can go as high as 100 kHz.

在声音频谱的高端，我们有高音扬声器，它们的声音来自鸟类的高音。 高音扬声器通常覆盖2 kHz-20kHz的范围，尽管某些专业高音扬声器的频率可以高达100 kHz。

Traditionally, tweeters were designed pretty much the same way as other speakers—just smaller. The trouble is that sound at that frequency is pretty directional, meaning that the highs in your music sound best when the tweeters are pointed right at you. Modern tweeters are starting to adapt a dome version that uses a soft dome diaphragm made from polyester film, silk, or polyester fabric that has been impregnated with a polymer resin. Dome tweeters are capable of a wider area of sound distribution.

传统上，高音扬声器的设计几乎与其他扬声器相同，只是尺寸较小。 麻烦的是，该频率的声音定向性很强，这意味着当高音扬声器正对着您时，音乐中的最高音听起来最好。 现代高音扬声器开始采用一种圆顶形式，该圆顶形式使用由聚酯薄膜，丝绸或浸渍有聚合物树脂的聚酯纤维制成的软圆顶隔膜。 圆顶高音扬声器能够在更大范围内分配声音。
