The speaker is the mouthpiece of the system that really makes a sound. It is the only electro-acoustic conversion "device" in this system that truly makes a sound, just like the singer's voice. However, if the "singer" is to open his voice, he must not support the amplifier. Obviously, the amplifier is the fundamental and key to the sound of this perfect HI-FI sound system. It is the true soul of the sound system. Visible amplifiers, and only amplifiers, it. It is the source of passion and energy for the entire sound system. Without it, everything will become eclipsed. Of course, this sound source, amplifier and speakers all play an irreplaceable function and role. They work together and are indispensable. It must not be biased. Real senior enthusiasts know that the matching of equipment is an important issue in the establishment of the HI-FI hi-fi system. What is the sound quality of a sound system? You can't just look at the quality of a piece of equipment in isolation. It should also be considered whether they are reasonable in the composition of the system, because, from a system engineering point of view, in a complete In the sound system, the front and rear audio equipment can be seen as a chain composed of several links, and the entire strength of the chain is equal to the intensity value of the weakest link. This is what is commonly referred to as "chain strength principle" in systems engineering. According to this principle, one of the most basic principles of the quality of various parts of the audio system is that the quality of each part of the equipment should be roughly equal or equal. This kind of matching can avoid the disproportionate weak link in the acoustic chain, thus affecting the overall quality of the system. When purchasing a set of audio equipment, be sure to put the speaker selection first. A pair of good speakers will be half the success of building a HI-FI sound system, which is the crucial last link in the entire HI-FI sound system. It is generally believed that the speaker has more than half of the sound quality of the sound system. In all kinds of equipment of the complete sound system, the personality of the speaker is the most prominent. Therefore, when building the HI-FI sound system, the speaker is the first device to be considered. Therefore, it is best to spend more time and more thoughts on this aspect, according to your current situation, such as listening to hobbies (multi-finger tone preferences) and use, listening environment and space size, capital investment, etc. Wait, after considering the thoughtfulness, first select a speaker that is enough to make you feel at ease, then choose other equipment such as amplifiers, audio sources and so on. That is to say, the so-called configuration method of pushing back from the system back-end equipment to the front-end equipment usually receives a multiplier effect. In the many influencing factors and links of the sound system, most of them are inextricably linked with the quality factors of the power amplifier. Such as the power of the amplifier and the size of the listening space, the control of the amplifier's low-frequency reproduction of the speaker, the energy perception of the medium and high frequency, the density and loudness, and the ability to penetrate the sound. And a high-fidelity audio system can finally show these pure HI-FI-level sound effects perfectly, all of which are closely related to the HI-FI quality of the power amplifier that is in the middle and the upper and lower. A pair of even better speakers, if there is not a match with the amplifier that is in harmony with it, it is determined that the perfect quality and excellent performance of the speaker can not be played normally. In the same way, there is only one outstanding high-quality sound source, without the amplification of a high-quality amplifier and the faithful transmission of the source. What is the beautiful and pleasant music listening experience? Undoubtedly, in a set of HI-FI sound systems that can perfectly represent the sound, the "soul" function of the amplifier is hard work. It is not only a source of abundant and dynamic energy providers, but also a blend of colorful music colors. The timbre and tone quality of a sound system is absolutely dependent on the tone of the power amplifier in it. Whether it is "biliary" or "stone", it is pure A or B. It is harmonic rich, sweet, dry, and tasteless. It is related to the sound and tone of the power amplifier. Who is still not convinced? Obviously, in a sound system, the power amplifier is the power source for the sound release of the entire sound system. It is completely controlling and depicting the beautiful music that is pleasant and pleasant, and is continuously presented in the three-dimensional space where each of our listeners is located. . Therefore, rather than saying that sound and space are inseparable, it is better to say that the power amplifier is inseparable from the space of listening. . In the sound system, all parts of the equipment work together and work together, which inevitably has a good or bad problem. The combination of the speaker and the amplifier is the most important. It includes the matching of the timbre characteristics, the matching of the speaker sensitivity and the amplifier power, and the matching of the impedance. In addition, the cooperation of the speaker and the listening environment is also very important. For the same pair of speakers, different listening environments may have very different playback effects. Speaking of environmental impact, it is really long. For the importance of listening to the room, it is not an exaggeration to say that it is part of the entire sound system, or "an audio equipment." As mentioned above, the entire sound system from the signal source to the speaker can be seen as a chain, and the listening room is an extension of the end of the chain, which is "connected" to the speaker. Therefore, its (influence) strength also has a negligible effect on the strength of the entire chain. When we listen to the music in a room, the sounds we hear are both direct sound from the speaker to the ear, and reflected sound reflected from the wall, including once and twice, and multiple reflections. The distance that the reflected sound reaches the human ear is longer than the straight-through sound. Therefore, when it reaches the human ear, it is later than the direct sound in time, that is, there is a delay. Due to the presence of reflected sound, a reverberation is formed in the room. Reverb means that when the sound source is turned off, the sound does not disappear immediately, but it is delayed for a while in the room. The length of this period is usually expressed in terms of reverberation time. In terms of terminology, reverberation time refers to the time required for a room sound level to decay by 60 dB after the sound of a point source is stopped in a relatively closed listening event. The length of a room reverberation time plays an important role in replaying sound quality. When replaying music indoors, we hope to have some reverberation. But on the other hand, I hope that the reverberation time should not be too long. Under normal household living conditions, the reverberation time generally does not exceed 1 second (s), preferably around 0.3-0.5 seconds (S). The reverberation time is longer and the sound is lively and active. When the reverberation time is too long, the sound will become less clear, the stereo position will become blurred, and the reverberation time will be appropriate. In this room, the sound will obviously feel round and resistant. It's also very important: the larger the room you listen to, the more reverberation time you can tolerate, or longer. That is to say, in a larger sound quality room, such as a theater, a large stadium or a large empty hall, you can hear the smooth and rounded echo of the valley, which is like a natural echo. The professional name is: echo is the phenomenon that occurs when the same sound arrives at a certain listening point (domain) for more than 50 milliseconds (MS). It can be imagined that in order to get a beautiful reverberation of nature and a resounding echo of the valley, the average family room is very difficult to achieve. The learning here is big. Still come slowly. Professional audio acoustic engineers, most of them have a wealth of sound knowledge and experience, according to the help of professional monitoring equipment, after a cleverly dressed home listening room, can create a miracle to a certain extent. This is why the same set of sounds has a very different effect on the sound reproduction in a completely different environment. So, how can we measure or roughly judge whether the natural reverberation of our listening room is appropriate by our own judgment? Have. The easiest way is to stand in a relatively closed listening room (closed door, window, etc.), and the palms of the two hands collide to hear the sound of the sound. According to the texture of the sound that I have heard, is it clear, natural, full and loud, and is there any feeling of echo (sound)? Still dry, smashing, smashing, sharp, and getting smaller. If it is the former, it indicates that your listening room has good acoustic characteristics, which is professionally called “live†sound quality room; otherwise, it may be due to excessive sound absorption, resulting in natural conduction and diffusion of sound waves, resulting in stagnation. The sound of the room sounds dry and dull, and there is no pleasing beauty, which is professionally called the "dead" sound quality room. In this listening room due to excessive sound absorption, you may want to hear beautiful music. This over-sounding room is like an artificial closed sound-absorbing room. How can you let your sound naturally release high-fidelity music, which is much worse than the natural open space environment. It can also be seen that the quality of the listening environment is also an important part of the sound quality of a sound system. The main factors that affect the acoustic properties of the listening room are: reflection, absorption, diffusion, size of the room, and geometry. The magnitude or amount of reflection and absorption has a series of correlations and effects with the material composition and structure of the object that produces reflection and absorption. There are many experts' monographs in this area that give a more detailed interpretation. The words are back to the topic. It is still more important or important to talk about the combination of speakers and amplifiers. Just say the speaker. The sound mechanism of the speaker and the instrument (non-principle) is very similar. We say that the design and manufacture of HI-FI audio equipment has both a scientific side and an artistic side, which is the most prominent in the speaker. Rather than saying that a speaker is an acoustic device, it is better to say that it is an instrument. And some of the most valuable instruments, such as the world-famous Italian meinari, are rare treasures. Therefore, a "treasure" class of musical instruments is a miracle, and most people can easily imitate it. At first glance, the speaker seems to be the simplest device in the sound system, but it is a box with two or three speaker units and a crossover network. In fact, it is not easy to make a high-fidelity speaker with excellent quality. I even think that the DIY masters who are passionate about speaker production know well. But the manufacture of HI-END-class amplifiers is by no means easier than the production of speakers. I don't know if you noticed it. In the world audio industry, how many top-level speaker design masters have been remembered by future generations? Remember more of the masters of the eternal amplifiers. Who else still doesn't believe? As mentioned before, a good speaker is like a good instrument. As far as musical instruments are concerned, no matter how good the top artists or high-ranking people are, even the best instruments are also furnishings. And so on, no matter how good the speaker, if there is no good amplifier to push, it is not good. In other words: the instrument is the human being, the talent is the soul that makes the instrument produce a beautiful sound. Music As for audio equipment, amplifiers are the source of power for audio equipment to reproduce beautiful music. Look at your listening room: (funny.) Is the speaker standing by? Look at where you put the amplifier and the sound source, you won't put it in that bowl. (Frank and funny again with you.). Just want to have a fun. This is the point of even insistence: the purchase of equipment must give priority to a pair of speakers, and then, when used around the speaker to match the front-end equipment, it highlights the soul of the amplifier. This is also the point that even once insisted: In a well-matched Hi-Fi audio system, the sound source is the source of the blood of the entire sound system, and the speaker is the mouthpiece of the system. The amplifier is the soul of the whole sound system engineering. Who is the soul in discussing the source, amplifier and speaker, and even the listening environment? Who is the body? There will definitely be a "spoken war." I will wait and see. But I am still even. Firmly believe that the amplifier is a sound system that is the soul of HI-FI (may be qualitatively more critical). There isn't a high-quality amplifier that is HI-FI-class, and you can easily enjoy the sound of listening to music and the fascinating music. If you don't think so, you will slowly toss it. In the forum, everyone's remarks can be believed to be rigid and arrogant, but the final result or purpose is only one: for the original source. Also HI-FI fever dreams a real destination. If there is a point of support for the couple, I will be convinced that this gentleman will no longer have a detour to go from now on. . A fever trip in full bloom.
