There are two types of sound systems: integrated and layered. In an integrated combination sound system, all parts of its circuits (including the phonograph) are housed in a single casing, which is generally used in low-end combination sound systems. In a layered combination sound system, the number of layers divided varies depending on the grade of the machine. Among the multiple layered combination audio systems, there are: one layer for record players, one layer for CD players, one layer for tuners, one layer for dual card recording and playback stands, one layer for tone controllers, and one layer for main power amplifiers. In a combination sound system with fewer layers, the jukebox and CD player each have one layer, while the others have one layer. Miniaturization, digitization, specialization, and film and television are inevitable trends in the development of home audio.

Folding miniaturization

Micro desktop combination audio systems have a long history of development, with advanced and ultra small combination audio systems appearing more than 10 years ago. However, due to the lack of effective solutions for listening speakers, stereo records, and recording cartridges, they have remained at a lower level. To create a compact audio world, not only do we need to focus on amplifiers, control components, left and right speakers, but we also need to consider the tuner, CD player, and recording card holder together.

Folding digitization

Digital technology is a new technology, so digital audio has developed to solve the distortion problem of analog audio noise. After the use of digital technology in the audio system, the recorded digital signals have clear resolution from sampling frequency to quantization characteristics, without color jitter, resulting in a very clear image. And it can be interchanged with the upper computer, which is incomparable to analog recording and playback devices. Digital recording can record the time, person name, and address into the tape, and use a micro keyboard to complete the cataloging work. By changing the track number, and adding remote control function, you can automatically search for the desired track, making it convenient to use.

Folding Film and Television Listening

With the development of electroacoustic technology, film and television technology, and computer technology, digital audio can form an integrated multimedia film and television audio system in homes. Such a system can hear various required signal inputs and function conversions added at the input end, and through computer processing, the audience can see various images and hear various sounds.
