不知不觉间，卡拉OK传入我国已有二十余年之久。这种几乎人人都天生可为的娱乐形式非常符合国人喜歌乐唱的习性，故尔历久弥新，长盛不衰。多年来卡拉OK的形式不变，但是卡拉OK的器材设备却历经几次革命性的变革。如今，虽然卡拉OK改叫“KTV”的多了，但是唱歌的主要功能和娱乐内容至今不变。如今，客人们更关心“唱歌轻松度”这个问题。因为不论是在美女如云、纸醉金迷的夜总会，还是在斋歌寡唱的量贩式KTV，“唱歌的轻松自然度”同样地备受关注，“唱歌费力、不轻松”同样都被国人厌恶，唱歌轻松自然舒畅的感觉成了大家共同的追求。那么，为什么有的音响唱歌会费力、不轻松？应当如何解决呢？

Imperceptibly, Cara OK has been introduced to China for more than 20 years. This almost everyone born for the form of entertainment is in line with the epithalamium music sing the habit of the Chinese people, therefore timeless and enduring. For many years, the form of Cara OK unchanged, but Cara OK's equipment has undergone several revolutionary changes. Today, although the Cara OK to change the name of "KTV", but the main functions and entertainment content of the main entertainment. Now, visitors are more concerned about the issue of "singing and relaxing". Because no matter is in the beautiful clouds, glamorous nightclub, or in the sing song Zhai oligo KTV, "singing the relaxed nature" also attracted a lot of attention, "singing laborious, not easy" was the same loathed, feeling relaxed and natural and comfortable singing into the common pursuit. So, why some audio and music can be difficult, not easy? How to solve it?

通常，影响唱歌轻松自然度、并使人们唱起歌来感觉费力的原因有以下几个方面：

Usually, the influence of the song to ease the nature, and make people sing songs to feel the difficulty of the following reasons:

1. 音箱频响曲线有缺（凹）陷、不平衡。音箱曲线不平衡的状态有多种不同，通常：以目前两分频KTV音箱而言，10寸或12寸泡沫胶边低音单元配3寸纸锥盆小高音的两分频音箱，为了使3寸纸盆高音相对安全，设计时都不得不把高音的分频点向上移，因此这一类两分频KTV音箱在中高音区都有“山谷”状的曲线缺陷（凹缺），由于这个频段局部缺声，音箱无法正常完整地重放（表现）出这中频段的声音，造成中频段的声音能量很弱。所以，这一类的两分频音箱虽然听歌时感觉相对“柔和”（暗淡）“干净”一些，但是由于音箱局部缺声，人声（话筒声）无法真实自然重现，因此人们就会感觉唱歌费力、不舒畅。

1 speakers have a lack of response curves (concave), uneven depression. Sound box curve is different, usually: the current two frequency KTV speakers, 10 inch or 12 inch foam glue edge bass unit with two inches of paper cone, in order to make the 3 inch high relative safety, the design of the two frequency KTV speakers in the middle and high notes are "Valley" shape of the curve defects (concave), due to the lack of sound in this band, the speaker can not normally complete the sound, resulting in the band's sound energy is very weak. So, this kind of two frequency sound although songs feel relatively "soft" (DIM) of "clean", but since the speaker local lack of sound, vocals (microphone) cannot true natural reproduce, so people will feel singing laborious, uncomfortable.

济南音响解决方法： ①换用三分频KTV音箱。三分频KTV音箱有一个专门重放中高频段声音的中音喇叭，弥补了低音喇叭有效上限不够高和3寸纸锥盆小高音喇叭有效下限不够低的缺点，提升中高频的能量，又提升了频响曲线的平衡自然度，使该有的声音全有，声音的重放更全面、更真实自然，听感明亮清晰而自然，拿话筒唱起歌来该有的声音全有，人声（话筒）的重放没有缺（凹）陷，音响原原本本地把人声放大了音量，因此三分频音箱使人唱歌感觉轻松、自然、舒畅，不费力。

Ji'nan sound solution: a three frequency KTV speaker. Singing without missing some of the shortcomings of the upper limit of valid three frequency KTV speaker has a special playback in high frequency band voice Alto horn, make up the bass horn is not high enough and 3 inch paper cone tweeter horn effective lower limit is not low enough to enhance the high frequency energy, but also enhance the frequency response curve of the balance of nature, the sound, the sound playback of a more comprehensive, more real and natural, listen to the sense of bright clear and natural, took the microphone to sing songs to the sound, voice (microphone) playback (concave) depression, the sound to the original local the vocals to enlarge the volume, so the three centses speaker makes people feel relaxed, natural, comfortable, not laborious.

②如果包房空间很大，反射强度不大，可以换用两分频的高品质专业音箱。两分频专业音箱（38芯或44芯以上驱动头高音配号角加布边低音的音箱）的大功率大音圈高音单元本来频响有效下限就足够低，再加上配用号角后增强了中高音的能量，因此用这种单元做分频衔接时，频响曲线很容易衔接得平衡自然，中高音区不会存在物理特性的声学缺陷，所以和三分频KTV音箱一样：声音明亮、清晰、自然，该有的声音全有，高保真度的状态容易实现，唱歌便相对轻松、不费力。有些人听惯了有凹陷的“柔和干净”的声音，在纯粹听音乐时，他们也许不喜欢明亮风格的声音，认为那样的声音“不耐听”。可是无论是喜欢柔和，还是偏爱明亮音色的人，当亲自拿起话筒来唱歌时，大家都会不约而同地喜欢上音色明亮清晰的音箱，因为这类音箱唱歌的确是相对更轻松舒服。如今的所有前级效果器，音乐和话筒人声都是可以分开来调的，如果想让音乐声相对柔和一些，只需要在音乐通道上把影响声音柔和度的几个频点略作衰减，柔和的音乐声立马呈现，而若是话筒人声原来就刚好明亮清晰而不过份、不啸叫（飞咪），话筒的均衡（EQ）大可不必多调，只需调整适量的混响效果比例及音量比例使之唱歌轻松舒畅便可。

If the room space is very large, the reflection intensity is small, can be used for the two frequency of high-quality professional speakers. Two frequency professional speakers (38 core or more than 44 core drive tweeter distribution angle and edge bass speaker) of high power high tone ring tweeter originally effective lower limit of frequency response is low enough, and equipped with horn enhanced ALT energy, so the unit as a dividing cohesion, frequency response curve easily join the balance of nature, the treble area does not exist physical characteristics of acoustic defects, so the three frequency KTV speaker as: sound of a bright, clear, natural, the some sound, high fidelity of easy to implement and singing are relatively relaxed, effortless. Some people listen to the sounds of the "soft and clean" of the depression. They may not like the sounds of a bright style when they listen to music ". But whether it is like a soft, or prefer a bright tone of the people, when you pick up the microphone to sing, we will invariably like the sound of a bright and clear sound speakers, because this type of speakers is relatively more comfortable singing. Now all the preceding stage effects, music and microphone vocal are can be separated to. If you want to let the music sound relatively softly, only need to on the music channel on the influence of soft voice several frequency slightly attenuation, sound of soft music immediately, and if vocal microphone originally just clear and bright and is not excessive, howling Fei Mi and microphone equalization (EQ) unnecessary multi tone, just proper adjustment of the reverberation effect ratio and volume ratio to singing is relaxed and comfortable can be.

2、前级或合并功放的混响效果没有调好，或前级的品质性能较差。前级或合并功放都是通过“混响”、“回声”、“延迟”的调校比例来模拟还原人声在自然混响空间内的声音。由于卡拉OK有相当大声的音乐伴奏声，因此调校合适的“混响量”、“回声次数”、“延迟的时间”才能恰如其分地突出效果，使人声既能自然地溶合到音乐之中，还能冲破音乐的包围，明亮而自然地突出，让歌者不太费力唱，就能清晰地听见自己的歌声，从而唱歌感觉轻松舒畅。即使音箱的品质好、不缺声，但是前级品质性能不佳或没有调好效果，其感觉是唱歌人声虽然保真度不差，但是声音干硬、毫无“水份”、唱歌费力。

2, the former level or the combined effect of the power amplifier is not well adjusted, or the poor quality of the former. The pre - or combined power amplifier is used to simulate the sound of the human voice in the natural reverberation space by using the ratio of the reverberation, echo, and delay. Due to the karaoke quite loud music accompaniment sound. So tune in the school the right amount of reverberation "," echo times "," delay time "can appropriately highlight the effect, the voice can naturally fused to the music, can break through the music surrounded by bright, naturally prominent, let the singer is not too much trouble to sing can clearly heard their song, and sing the feeling relaxed and comfortable. Even if the speaker's quality is good, no lack of sound, but the poor quality of the pre - grade or no good effect, the feeling is that the singing voice is not bad, but the sound is hard, no water, singing effortlessly.

济南音响解决的方法是： ①换用品质性能较好的前级；

Ji'nan sound solution is: first, the use of a better quality performance of the first class;

②找专业人士调出大众所需的混响效果。

To find out the effect of the public's need for the public.

3、音箱的灵敏度低、功放功率小。音箱的灵敏度低和功率小也是让人感觉唱歌费力的原因之一。在相同的功放率输出状态之下，灵敏度高的音箱发出的声音相对更大，灵敏度低的音箱发出的声相对小。灵敏度低功率又小的音箱发出的声音小，让人感觉唱歌时人声不够宏亮大气，因此感觉唱歌费力。由于音箱灵敏度不够高，功率又不大，功放的功率也小，调音师为了保证音响设备的安全稳定和耐用，一般会尽量控制声压（声音的响度），致使声音不够大，动态出不来，因此让人唱歌费力、不畅快。

3, the speaker's sensitivity is low, the power amplifier. Low sensitivity and low power of the speaker is one of the reasons why people feel like singing. Under the same power output rate of the output state, the high sensitivity of the sound box is relatively large, low sensitivity of the sound of the sound is relatively small. Sensitivity of low power and small speakers from the small voice, let people feel singing voice is not loud atmosphere, so I feel singing laborious. Due to the speaker sensitivity is not high enough, power and little, power amplifier is also small, tuner in order to ensure the security, stability and durability of the audio equipment, usually try to control (loudness) pressure, resulting in a sound is not big enough, dynamic get out, so people singing and laborious, not fun.

济南音响 http://www.jnzqyx.com/ 解决方法： ①换用灵敏度高、功率大的音箱； ②换用功率大的功放。一般功放的功率最好比音箱的额定功率大三分之一以上至2.5倍之间。

Solution: the use of high sensitivity, high power speaker; II for the power amplifier. The power of the general power amplifier is better than the rated power of 1/3 to 2.5 times greater than the speaker.

4、话筒品质差。话筒是人声拾音的设备，也就是人的声音进入音响系统放大还原重放的唯一途径。如果话筒的曲线不平衡，有凹缺，就无法真实全面地拾取人声信号，造成人声局部缺声。一旦缺声，人唱歌就会觉得声音出不来，犹如被人掐住喉咙一般，感觉费力。如果话筒的频响凹凸不平、曲线起伏过大，人的声音就会变怪异、还原度差，声音不自然有解决方法：换用频响宽、不缺声、灵敏度适中的话筒音头（俗称咪芯）。如果是无线话筒，还得整体考虑，因为发射器和接收器的品质性能都可以影响音质音色，不仅仅是咪芯的问题。

4, microphone quality difference. Microphone is a device for human voice pickup, and it is the only way to amplify and replay the audio system. If the curve of the microphone is not balanced, there is a gap, it is unable to fully pick up the voice signal, resulting in a partial voice. Once the lack of sound, people will feel the voice singing out, like being around the throat, feel laborious. If the microphone frequency response is uneven, curve fluctuation is too large, the voice of the people will become strange, reduction degree difference, the sound is not natural solutions: for a wide frequency response, not lack of sound, moderate sensitivity microphone sound head (commonly known as the core of the MI). If it is a wireless microphone, but also the overall consideration, because the quality of transmitter and receiver can affect the quality of sound, not only is the problem of microphone.
