家庭影院音箱根據頻率來區分動圈式單體，有幾種需要了解，下面來講講吧。
In general, the speakers of home cinemas can be divided into moving coil units according to frequency. There are several types that need to be understood. Let's talk about them below.
1、超低音單體：工作范圍大約在 15 赫茲到 200 赫茲。
1. Subwoofer unit: the operating range is about 15 Hz to 200 Hz.
30 赫茲以下人耳不容易聽見，但身體會感受到。像電影中出現的地震場面，或是火箭發射的震撼感，超低音擁有足夠的量感及衝擊力，能讓聽者獲得相當大的滿足感。
It is not easy for people below 30 Hz to hear, but the body can feel it. Like the earthquake scenes in the movies, or the shock of the rocket launch, the subwoofer has enough sense of volume and impact to make the listener feel quite satisfied.
2. 低音單體：工作范圍大約在 30 赫茲到 3k 赫茲。
2. Bass unit: the working range is about 30Hz to 3kHz.
低音單體需要較大的體積才能產生較好的表現，作動出厚實的低音，因此低音單體的直徑多在 8 吋以上，又以 12 吋或 15 吋為普及，常見于 KTV、舞臺等寬闊的場所。
The bass unit needs a large volume to produce a good performance and to produce a thick bass. Therefore, the diameter of the bass unit is more than 8 inches, and 12 inches or 15 inches are popular. It is commonly used in KTV, stage and other wide places.
3. 中音單體：工作范圍大約在 200 赫茲到 4k 赫茲之間。
3. Medium tone monomer: the working range is about 200 Hz to 4kHz.
中音域是分佈在人耳敏感并且訊源集中的區域，中音單體的發聲表現往往能夠做到逼真還原，音色乾淨有力，且讓人感受到強烈的節奏性。
The middle range is distributed in the sensitive area of the human ear and the signal source is concentrated. The vocal performance of the middle range can often be realistically restored, the sound color is clean and powerful, and people feel strong rhythm.
4. 高音單體：工作范圍大約在 2k 赫茲到 20k 赫茲之間。
4. Tweeter: the working range is about 2KHz to 20kHz.
訊源中的樂器，像是小提琴、吉他等等的樂器都包含了泛音，所以高音單體通常都必須設計成 20k 赫茲才行。
The instruments in the source, such as violin and guitar, all contain overtones, so the high pitched unit must be designed at 20kHz.
5. 超高音單體：通常是指超過人耳聽覺上限 20k 赫茲的高頻，工作范圍大約在 4k 到 40k 赫茲。
5. Ultra high frequency monomer: usually refers to the high frequency exceeding the upper limit of human hearing 20kHz, and the working range is about 4K to 40KHz.
另外還有二種單體的組成形式，這二者因為外觀都是一個單體組成的揚聲器，很容易將這二者搞混:
In addition, there are two forms of monomer composition, which are easy to confuse because the appearance of the two is a single speaker:
同軸單體是復合式設計，先經過分音器將音頻分成二音路或三音路 ，同軸是將高音與中/低音單體，裝置在同一個單體中，由于採用同一條軸心線，因此稱為“同軸”。關注我們

The coaxial unit is a composite design. First, the audio is divided into two or three sound paths through a sound divider. The coaxial unit is a unit of high and medium / low sound, which is installed in the same unit. Because the same axis line is used, it is called "coaxial".
