音响有一体的和分层的两类。 在一体的组合音响中，它的各部分电路（包括电唱机）都在一个外壳之中，这种结构一般用于低档的组合音响中。在分层的组合音响中，根据机器的档次不同所分的层数也不一样。分层较多的组合音响中有：电唱机一层、CD唱机一层、调谐器一层、双卡录放音座一层、音调控制器一层、主功率放大器一层。在分层较少的组合音响中，电唱机、CD唱机各分一层，其他为一层。微型化、数字化、专业化、影视化是家庭音响必然的发展趋势。
There are two kinds of sound: one is integrated and the other is layered. In the integrated combination sound, all parts of the circuit (including the record player) are in a shell. This structure is generally used in low-grade combination sound. In the layered combination sound, the number of layers is different according to the level of the machine. There are more layers of the combination sound: a layer of record player, a CD player, a tuner, a double card recording and playing stand, a tone controller and a main power amplifier. In the less layered combination sound, the record player and CD player are respectively divided into one layer, and the others are one layer. Miniaturization, digitization, specialization and film and television are the inevitable development trend of home audio.
微型化
miniaturization
微型台式组合音响已有较长的发展史，在10多年前就已经出现高级超小型组合音响。但由于听音喇叭、立体声电唱机、录音卡座没有很好解决，所以一直停留在较低的档次上。为了创造小巧的音响世界，不但要从放大器、控制部件、左右音箱上下功夫，还得从调谐器、CD唱机和录音卡座方面一起考虑。
The mini desktop combination audio has a long history of development, and the high-grade super mini combination audio has appeared more than 10 years ago. But because of the problems of loudspeakers, stereo players and recording cassette, they have been staying at a lower level. In order to create a compact audio world, we should not only work hard on amplifiers, control components, left and right speakers, but also consider the tuner, CD player and recording cassette.
数字化
digitization
数字技术是一种新技术，所以数字音响在解决模拟音响噪声的失真问题时发展而成。音响采用了数字技术之后，记录的数字信号从取样频率到量化特性，有清晰的解像度，没有色抖动，得到是非常清晰的图像。而且可以和上位机互换，这与模拟录放像设备无法比拟。数字录音可以把时间、人名、地址一起录入带中，采用微型键盘来完成编目工作，更换曲目编号，再加上遥控功能，使你能够自动地搜索需要的曲目，使用方便。
Digital technology is a new technology, so digital audio is developed to solve the problem of distortion of analog audio noise. After using digital technology, the recorded digital signal has clear resolution and no color jitter from sampling frequency to quantization characteristics, and the image is very clear. And it can be interchanged with the upper computer, which is incomparable with the analog recording and playing equipment. Digital recording can input the time, name and address into the tape together, use the micro keyboard to complete the cataloging work, change the track number, plus the remote control function, so that you can automatically search for the required track, easy to use.
影视听
Video audio visual
数字音响随着电声技术、影视技术、计算机技术的发展，它们在家庭中可以构成浑然一体的多媒体影视音频系统。这样的系统，能听到各种在输入端增添各种需要的信号输入和功能转换，通过电脑处理就能使受众看到各种图像和听到各种声音。
With the development of electroacoustic technology, film and television technology and computer technology, digital audio can form an integrated multimedia video audio system in the family. Such a system can hear all kinds of signal input and function conversion needed at the input end. Through computer processing, the audience can see all kinds of images and hear all kinds of sounds.
