Speaker Problems Come and Help 5, Speaker Problems Come and Help Quickly

ong ong should be low-frequency self-excited or jamming.

Let friends who can repair TVs and stereos add and change capacitors!

Replace all capacitors with electrolytic capacitors from famous manufacturers" -- don't mess around!

Ceramic capacitors are high-frequency bypass.

Electrolytic capacitors are sound-frequency coupled and filtered.

High-quality tantalum capacitors are the best for audio frequency coupling, but they are a little higher.

Electrolytic capacitors have different capacitances, different withstand voltages, and different applications.

Because there is a continuous ring, it means that the amplifier part is working, and the fault should be in the audio output part, which is likely to be an output short circuit. You can check it out of the box yourself, if it is a short circuit should be easy to handle.

It's garbage, and it's refreshing to throw it away.

If it's for appreciation, yes, it's best; If you play games, naturally.

By the way, I am defiled**, and people who really appreciate ** use speakers. That's HIFI level,It's the same with computer speakers,Really good speakers suitable for appreciation**Yes。 It doesn't mean there is no bass.

Used to listen**, just kidding, no matter what CD you can buy at the moment, *** audio or Blu-ray, you can't reach it, so many channels, it will only mess up the soundstage.

Audio supports real, but unfortunately not popularized and not easy to buy. Blu-ray concert discs are available, but in addition to being difficult to buy, **high, at most, there are only.

If the landlord mainly appreciates jazz, percussion, rock music, etc., it can also be used. But it's strange,It seems that most manufacturers don't think that the speaker is used to enjoy**,Whether it's sound quality or**obviously lower than a grade。

But not everyone can tell the difference in sound quality,Like putting a *** and the like, 2000 pieces of computer speakers,It's not very obvious,Not to mention multiple subwoofers。

Listen to ** buy.

Watch a movie and buy it. It has nothing to do with bass and treble!!

Impedance is the coil of the speaker, and the smaller the resistance, the smaller the power of the speaker that needs to be pushed.

Frequency response: This is the speaker that reacts to an audio signal whose frequency is within the range of the frequency that is indicated, which means that if the input audio frequency is in this range, then the speaker will sound.

The use of bandwidth: 150-20kHz -6db This is the input audio in this range, generally there will be no good sound reproduction, weak exceeded, there will be noise.

Sensitivity: 110db spl 1w at 1m This is the input of 1W of power 1m in front of the speaker The measured volume dB is decibels.

Maximum SPL: 145dB SPL Peak Power is increased to the rated maximum power is measured at 1m directly in front of the speaker.

There is also high, medium and low frequencies, which generally have a frequency range.

I've used this box. The specific parameter decomposition has been made very clear upstairs. I won't go into details.

I'll talk about the rest of the story.

The segmentation of the audio is artificially separated. How to listen to it, is a very abstract concept.

You can find a frequency generator. Separate the different frequency bands and listen slowly. When you get used to listening, your ears will remember it and you will be able to distinguish it clearly.

The reason why you feel like you can tone up to the same right now is because you're still in the beginner's stage.

Don't worry, you can feel it slowly.

After feeling it, consolidate and improve again.

1. The impedance is for the audio voltage, and it must be matched with the power amplifier, that is to say, the voltage and current of the power amplifier output are determined according to the impedance, if the impedance is small, the current of the power amplifier will exceed the rated and be damaged, and the impedance is large and cannot reach the rated power, and the output voltage is too high and will burn out the power amplifier. 2. High frequency, medium frequency, low frequency is judged according to people's hearing, of course, there are special equipment to test, the sound should be debugged according to the need, such as the requirement to put rock, low frequency to increase, medium frequency to attenuate, if it is a meeting venue, then the medium frequency, high frequency to improve the low frequency to decrease.

Your Tianyi amplifier is a brand-name award-winning amplifier, and the sound source is not bad.

The speaker is not good, it is the quality of the speaker's speaker--- the silver flute speaker has long been discontinued--- state-owned speaker factory has long collapsed, and now it is operated by private individuals, and the speaker may be an impostor, so the sound quality of the speaker is poor. In addition, the speaker is a copycat DIY, not designed by speaker experts. The sound quality is not very good.

Huiwei is a brand-name speaker, but also a brand-name speaker, the speaker is designed by experts, and the sound is of course good.

Cooking horns is a rookie problem, and a good speaker doesn't need to be boiled at all, and the sound quality is very good.

Maybe it's because the sound source is not good, you connect the amplifier to the computer, listen to the computer audio source, there may be a difference in the sound, if it is still not good, the speaker speaker is not good.
