R stands for right channel, L stands for left channel.
The principle of two-channel sound is that when people hear sound, they can judge the specific location of the sound source based on the phase difference between the left ear and the right ear. On the circuit, they often transmit different electrical signals. In the process of pursuing stereophonic sound, due to technical limitations, electroacousticians could only use two-channel sound in the early days.
Dual-channel is the principle of stereo sound. Two speakers are placed in the space at a certain angle to each other, and each speaker is provided with a signal from one channel.
The signal of each channel is processed during recording: the processing principle is to imitate the biological principle of the human ear when hearing sounds in nature, which is basically two sounds in the circuit. The channel signals are different in phase, so that when you stand at the intersection of the axis lines of the two speakers and listen to the sound, you can feel the stereo effect.
Extended information:
Headphones can convert the electrical signal of sound into sound. There are two-channel and multi-channel systems in the existing technology, although they have obvious sound and image distribution.
They are developed on a line or a plane. A complete stereo system should be a surround sound system containing three-dimensional space.
Three-dimensional stereo sound is transmitted and reproduced using a four-channel system. At this time, the four speakers should be located in the four directions of the sound room. To pick up three-dimensional stereo sound, four simultaneous speakers with centroid directional characteristics can be used. Model microphones have their main axes of pointing characteristics pointing to the four directions of the studio.
It is more expensive to use a four-channel stereo system to obtain three-dimensional surround sound. Therefore, in actual use, two-channel stereo is often processed to produce a simulated surround sound field.
The special design of this patented product makes it superior in use and has a wide range of applications. Such products will receive more widespread attention after being introduced to the market.
The traditional headphones used have various defects. Since they have been in the market for a long time, they will still pose a certain amount of competition to patented products. The competitive environment of the market can be divided into four forms, namely perfect monopoly, oligopoly, monopolistic competition and perfect competition.
Based on the characteristics of the market, the market is a monopolistic competition market. Moreover, as the market share of this patented product increases, its corresponding similar products and imitations will also appear, and this trend of monopolistic competition will become more and more obvious.
Dolby Digital, THX and DTS technologies, these technologies can be called standard surround sound technologies. Of course, they are undeniably the best surround sound technologies at present, but they also have certain limitations in application. Restrictions such as expensive equipment, strict listening environment requirements, and sufficient software are required, but people cannot achieve it at certain times and under certain environmental conditions or due to economic constraints.
This three-dimensional stereo headset can be used with computers, as well as with VCD, DVD and other devices that can obtain stereo sound (it can also be used with VCD, DVD and other devices that can obtain stereo sound).
It is used to listen to existing surround sound, and can also develop a four-channel three-dimensional spatial stereo system. The technical difficulty of this system is far lower than that of surround sound technology, and it only needs to be twice as long as a two-channel system. Computer sound cards, DVD and VCD chip processing technology will also see changes.
This system may be the final development trend of stereo systems and will replace the existing single, dual and surround stereo systems. Generally speaking, when this patented product is put on the market, it can be directly used to listen to existing surround sound, or it can also be used to develop a four-channel three-dimensional space stereo system.
