What happens if you increase the power output of your speaker

It doesn't matter, because the transformer is actually converted into electrical energy, and the magnetic strong coupling is used for energy transfer, and then the magnetic strength is converted into electrical energy, and the voltage is related to the ratio of the number of turns before and after the coil and the input voltage, and finally the voltage is rectified, AC to DC!

The current is related to the load, the nominal current of the transformer means that the maximum current value that he can safely output is 800mA, which does not mean that he must have such a high output current!

According to Ohm's law, if the output current is 4 times the original and your load does not change, then the voltage will be 4 times the original one, which is 36V, and the transformer will not have that high output voltage!

So, use it.

The horn is a rough device, which may overheat, bring safety hazards and shorten the lifespan, at least it is necessary to use something else to divert 600mA.

No, even if it can be used now, it won't take long for the phone to burn your speaker.

As long as the voltage is suitable, the input above is 220V 50Hz 150MA

The output of 9V 800mA is just a special case, the maximum output power of this power adapter is calculated by P=UI, and your speaker power is, within the output range of the adapter, so don't worry, the output current at this time is, don't worry about matching with you, the voltage is the same as everything OK

It doesn't matter if the output current is large, if the current is small, there may be a loop, the current is proportional to the output power, the current is large, the power will hit, and the natural power consumption will be high.

Just try it.

A power supply with a current greater than or equal should be used. The power supply used is not good, if you just listen to the low volume, it may be able to make do. However, it will affect the sound quality (when the current is needed, the voltage will drop, which will affect the amplification of the sound waveform) and the original high volume will not be reached.

If the speaker turns on the loud volume, it is likely to damage the power supply.

The current is very important, the current is small, the power is small, so there will be a feeling that the treble can't come up, the bass is not heavy enough, and it will cause the power supply to heat up, easy to damage, it is recommended that you change it or 2A.

It's easy to burn the power supply, you better get a big current early, it's better to get a transformer, don't switch the power supply.

Yes, the current is smaller. The electronic settings can't come up.

The pony pulls the cart, and the power amplifier is in full load, which is easy to damage the power amplifier circuit.

In addition, the sound restoration is erratic, especially the bass is weak.

Therefore, the maximum power of the amplifier should ideally be equal to the maximum power of the speaker.

The sound of the stereo will not be very loud!

Why is the power supply of the audio right, you are so pro<>

The binding post behind the speaker has positive and negative poles. Most of the friends who have been in contact with the horn have done such an experiment, using a No. 5 battery, the positive and negative poles of the battery at the same time to touch the red terminal of the horn and another black terminal, we will find that at the same time the horn makes a "hissing" sound, the diaphragm of the horn will bounce outward, if you touch these two terminals in turn, the diaphragm of the horn will bounce inward. The red terminal is the positive pole of the horn, and the black one is the negative pole.

If we move over the speaker and look at the rear binding posts, you will see that one or two of them are red, and the other or two are black, and the color of these binding posts corresponds to the color of the terminal blocks of the speakers inside the speaker. At the same time, the color of the binding post behind the amplifier is the same. The speaker wire is reversed, there are two situations, one is to connect the red binding post behind the amplifier to the black binding post behind the speaker, and the other wire is also reversed, needless to say.

The other speaker is also connected in the same way. In this case, you won't hear anything wrong with the speaker playback. Because when the two speakers are working like a locust, the phase is the same.

Another situation is that the binding post of one of the speakers is connected to the same color as the binding post behind the amplifier, while the other speaker is connected in the opposite direction, which is not allowed in the sound system. This connection method causes the two speakers to play in opposite phases. In layman's terms, when the speaker of one of the speakers vibrates forward, the speaker of the other speaker vibrates backwards.

This causes the sound emitted by the two speakers to cancel each other out, which is often referred to by audiophiles as a "sound short circuit". When an "acoustic short circuit" occurs, the device will not be damaged, but the sound quality will deteriorate. The most obvious is that the bass is severely lacking, muffled, and the mids and highs are no longer clear, and the whole soundstage is chaotic.

Therefore, when we connect the speaker in the system, we must pay attention to it, and the second situation must not occur.

The power amplifier is small, and the direct result is that the sound is small, the sound field is compressed, and the strength is lacking.

Because the human ear does not perceive the loudness of each frequency equally. At low volumes, the loudness of both the low and high bands will be rapidly reduced, especially the reduction in the low frequency bands is more obvious, so there is a high and low bass adjustment on the power amplifier.

Generally, when the loudness balance is achieved, the sound pressure should reach about 80 decibels.

This is mostly a disturbing sound.

1. Generally from the signal line. Remove the signal cable and the interference will be much smaller.

2. The flickering of the fluorescent lamp will also cause noise, which is relatively short, and there are more when the light is on.

3. When the mobile phone signal is strong, it will also interfere with the audio, but when the signal decreases, it will disappear.

Mobile phone interference, it's not a problem inside the audio, replace those big filters to see.

Maybe it's a problem that affects the quality.
