The stereo manufacturer tells you the structure of the stereo
There are two types of audio systems: integrated and layered. In the integrated combination of audio, its various parts of the circuit (including the record player) are in a shell, this structure is generally used for low-grade combination of audio. In the layered combination of sound, according to the different levels of the machine divided into different levels. There are many layers in the combination of sound: a record player, CD player a layer, a tuner a layer, double card recording and playback base a layer, tone controller a layer, the main power amplifier a layer. In the combination of less layering sound, record player, CD record player is a layer, the other is a layer. Miniaturization, digitization, specialization and movie-making are the inevitable development trend of family acoustics.
Miniature desktop combined audio has a long history, more than 10 years ago, there have been advanced ultra-small combined audio. But as a result of listen to sound horn, stereo record player, record card is not very good solution, so stay in lower class all the time. To create a compact sound world, you need to think not only about amplifiers, control components, left and right speakers, but also about tuners, CD players, and record holders.
Digital technology is a new technology, so the digital audio developed in solving the problem of distortion of analog audio noise. After the adoption of digital technology, the digital signals recorded from the sampling frequency to the quantization characteristics have clear resolution, no color dithering, and the image is very clear. And can be exchanged with the host computer, which is unable to compare with the analog recording and video equipment. Digital recording allows you to record time, name, and address into a tape, use a tiny keyboard to complete cataloging, change track Numbers, and use remote controls to automatically search for tracks you need.
The film and television to listen to
With the development of electroacoustic technology, film and television technology and computer technology, digital acoustics can form an integrated multimedia film and television audio system in the home. Such a system can hear all kinds of signal input and function conversion needed at the input end. Through computer processing, audiences can see all kinds of images and hear all kinds of sounds.
