2. Background technology

With the advancement of digital science and technology, digital audio-visual products are becoming more and more popular, such as DVD audio-visual disc players or surround amplifiers, which basically have functions such as DOlby Digital or DTS decoding, which can decode digital signals and output analog signals to speakers for sound. First of all, there is a 5.1CH AUDIO OUT audio analog output terminal on the back panel of the DVD Player or the surround amplifier, so that "TV + DVD player + surround amplifier + 5.1-channel speaker" can construct the basics of a home cinema audio-visual environment. Secondly, although the multi-channel or 5.1-channel output can enable the listener to enjoy the sound quality, if the earphone is loaded, it is difficult to reproduce the original sound due to the limitation of the structure of the existing earphone, causing the listener to listen through the earphone. The sound quality I heard in the end cannot reach the original sound effect of 5.1 channels, especially the speakers of various channels have different characteristics, and the effect cannot be achieved by separating them, but that each sound room must match each sound The characteristics of the speaker can be effective. For example, the front main channel speaker is larger than other speakers, and its central area is a high-pitched area, and the central area is surrounded by a low-pitched area. The inventor has found that if the high and low areas are not separated, the high and low frequencies are easy to Mixed, the clarity of the sound received by the ear is poor; in addition, if the multi-channel or 5.1-channel speakers are combined in the same earphone without separating them by chamber walls, Especially in the limited headphone space, how to make various multi-channel speakers give full play to their unique sound effects requires long-term research and testing, and it is not easy for those who are familiar with this technology. Using the acoustic principle of the speaker and the physical effect between the sound chambers, it cannot be solved by the existing virtual 5.1 decoding function formed by electronic synthesis, because the virtual 5.1-channel headphones electronically synthesized are not the real 5.1-channel original sound It is a pity that there is distortion, and if the analog sound effect is not handled well, it is easy to interfere with the sound quality, so it is not a high-quality earphone.
