Many KTV industry insiders regard the ease of singing as the final basis for system quality. So why do some systems feel relaxed and some systems feel painful?
The biggest influence on the ease is the width of the range. Suppose that it is a sensation to sing karaoke with a normal TV sound system or with a portable radio. Although it is difficult to get rid of the feeling of difficulty by adding peripheral equipment to increase reverberation or motivation. The reason is that the range is too narrow. For private rooms, the understanding of the width of the range is more complicated. The first thing to distinguish is the vocal range or the musical range. This is because some systems that experience a narrow range of voices feel very wide when listening to music; on the contrary, some sound systems that are narrower in listening to music feel more normal when singing. The vocal frequency band is mainly in the range of 100-8000 Hz (temporarily ignoring some of the weaker harmonics of the signal). If there is a low valley defect in the range of 1000-8000 Hz, even a short period will feel that the treble is suppressed and the sound range is narrowed. At this time, if the frequency above 5000 or 8000Hz is normal, the range will still be felt when listening to music, but there are some levels missing. If there is a trough below 500Hz, even if 100Hz is raised, it will feel that there is no confidence in singing. Therefore, the vocal range of the vocal sense refers to the width of the straight section of the frequency response characteristic of the mid-band.
When the singer is singing, under the influence of psychological factors, he always wants to hear the sound from the speaker is a perfect sound, at least not lower than his original sing. Not to mention how much beautification, there are very few systems that can restore the original sound well, even for most brand-name products, but the defects are relatively small. If the range is narrow, you will feel that there is a missing part. This lack of repression in the high range is felt; it does not feel emboldened in the low range. When these two phenomena occur, the singer will subconsciously spend more effort to improve the sound of the defective segment under the influence of psychological factors, which is what people often say is "tired".
The second place for ease is sensitivity. The same system, always louder than the smaller ones, that is, with a small force can make a louder sound, naturally it is easy. On the surface, this seems to be more important than the aforementioned range. In fact, the sensitivity is closely related to the range. This is because, when the volume is turned to a certain degree, it will "whistle". What is the key factor to make it as big as possible and not to scream? Mainly frequency response characteristics. For a system with many peaks and valleys, there is a possibility of self-excited howling at each peak point. When the volume is turned on to satisfy the closed-loop gain greater than 1 (referring to the total closed loop of the electroacoustic system), this peak point is satisfied. Self-excited amplitude-frequency characteristics, once the phase-frequency characteristic satisfies the 0-phase, self-excitation must occur; likewise, if a system has a lot of valleys. Then, the amplitude limit of the straight section (for the time being, there is no peak) is a condition for avoiding howling. The volume is a comprehensive result, too much trough will reduce the average sound pressure level, and the result is that the volume is not large. Therefore, the flatter the frequency response characteristic of the system, the higher the average sound pressure level obtained, and the greater the volume of the experience.
The third element that affects ease is the sound. The most mentioned of this issue is the Hi-Fi industry. Make an assumption, there is a subwoofer speaker damage occurred "rub circle", what feelings concert? At this time, in addition to the normal sound emitted in the speaker , it is also mixed with an unpleasant friction sound. These extra sounds are sound dyeing. The form and degree of sound dyeing are varied, and some manifestations are that no matter the size of the sound, it always exists; some of them appear when the volume is loud; others are slight to just feel the sound of some rustling, as if The sound is superimposed on the seamless (Hi-Fi industry is called artificial flavor), and so on. Singing with a system with sound dyeing, it seems that the channel blocks a lot of things, the sound is hard to pass through, but with the nature of the blockage, the original sound is doped with a lot of extra things; It is as if the channel is abnormally smooth, it is easy to pass, and the sound naturally does not change much.
When some volume is loud, the sound is dyed, and most of them are caused by the small dynamic range of the system. The singer always felt that he didn't dare to sing loudly. There was a loud noise or even a tear, and it felt very uncomfortable. The extent of the dynamic range is reasonable and there is still controversy. However, a people-oriented business place should not blindly suppress the nature of consumers. Depending on the hearing ability of the human ear, the undistorted sound pressure level of 104 dB will still feel relaxed. According to the sensitivity of most speakers and the area of ​​20 to 40 square meters, the conversion success rate can reach 300W (here, not the average power, but the dynamic range maximum power). According to the Hi-Fi concept, it is necessary to have a large reserve power, and the hearing is easy and comfortable. Taking TPMPO speakers as an example, his design power of 250W8Ω is also based on this consideration.
The last one that has a greater impact on ease is the reverberation process, which is often referred to as the reverb effect. Reverberation is the most common method of artificially beautifying vocals. There are a lot of successful examples in both amplifiers and dedicated peripherals, so I won't go into details here. It is worth mentioning that the play of the residual sound has a lot to do with the quality of the system. This is because the residual sound is always weaker and weaker, and the higher the system's resolution, the more sufficient the residual sound can be restored. Traditional KTV speakers mostly use paper cones, and the crossovers are not as sophisticated as Hi-Fi. In addition, many measures are not enough. It is very difficult to achieve high resolution. A common remedy is to add an incentive function to the electrical system. In most cases, the factors that affect the clarification include: speakers , amplifiers, microphones, and transmission lines. More prominent among them are speakers and microphones.
Some speakers have introduced the Hi-Fi concept and focused on improving the ability to understand. Those who have heard of it will be surprised to find that this speaker can feel as if there is incentive without excitation. The effect is more real and natural than using an exciter. The reason is very simple. The former is manually compensated after the defects appear, and the latter is to minimize the loss from the beginning, and there is no need to make up for it. The shortcoming of manual compensation is that it is difficult to match what people want, not too much or less. More will produce a "dry" feeling, and it is easy to cause self-excitement. Less effect is not obvious. If the frequency band that is compensated is not appropriate, it will generate new peaks and valleys, and the problems mentioned above will occur. In contrast, it is still "original" as well.
The sound quality of karaoke speakers is the most concerned by the industry. As long as the scientific and rational design, clever selection of the materials used in the speakers , careful assembly and debugging, the sound quality of the new karaoke speakers can have a qualitative leap. Therefore, many high-pitched speakers , high-powered speakers , and strange cabinets have come out, BOSE301v, TPMPO-T804 belong to this product.
