What does speaker distortion mean? What is the distortion of the speaker

Distortion is when a sound system changes some part of the original source signal (waveform, frequency, etc.) after the sound system has played back the source signal. The distortion caused by the loud volume of the speaker will make the treble harsh, the midrange is unclear, and the bass is muddy, and distortion is a type of noise.

The distortion of the speaker is the distortion of the speaker,There is harmonic distortion when the subwoofer is turned on、Intermodulation distortion、Transient distortion,This is the characteristic of the coexistence of all dynamic speakers,I spent 35 years finally found a way——Magnetic field countermeasure method,Can solve all the problems existing in the speaker。 Now there are experimental and modified products that have been proven.

Features of the magnetic field countermeasure method:

1. Long stroke, 100mm.

2. Linearization is always a one-way relationship.

3. The thrust is large, and the use of neodymium magnet can achieve tens of thousands of N to trillion Ox.

4. No distortion, because linearization, nonlinear distortion, intermodulation distortion, and transient distortion do not exist.

5. The sound pressure is high, because the linear stroke is long, so the sound pressure is high.

6. High efficiency, the bigger the horn, the higher the efficiency.

7. The power is large, and the power must be large for a long stroke, and the stroke is twice as large as the power is 4 times, and then twice as large and 4 times larger.

8. In the full frequency band, the magnetic field countermeasure method can be equipped with an acceleration device, the higher the angular velocity, the greater the acceleration.

9. The dynamic range is large, because the stroke is long, the sound pressure is high, and the dynamic range is also large.

10. The sound pressure is easily 180 decibels.

11. Full frequency band, the loudspeaker can achieve 15Hz-25kHz because of linearization, so it solves the harmonic distortion, intermodulation distortion and transient distortion of the speaker.

The definition of distortion is basically the same as that of the amplifier, the difference is that the amplifier inputs an electrical signal and outputs an electrical signal, while the speaker inputs an electrical signal and outputs an acoustic signal.

Therefore, the distortion of the speaker refers to the distortion of the electroacoustic signal conversion. The allowable distortion range of sound waves is within 10%, and the average human ear is not sensitive to distortion within 5%. It is best not to buy a speaker with a distortion greater than 5%.

The distortion of an audio, i.e., distortion, is defined as the square root value of the ratio of all harmonic energies to fundamental energies. There are many kinds of distortion: harmonic distortion, intermodulation distortion, phase distortion, and so on.

The technical term we usually call distortion is Total Harmonic Distortion, or THD for short.

Distortion is the difference between the ratio of the amplified signal to the original signal compared with the signal before the amplifier amplification and the signal amplified by the amplifier, which is called distortion. It is measured in percentages.

The distortion of the sound is a parameter of the audio, that is, to input a signal to the audio, the audio will output a signal, the output signal of the audio is compared with the input signal of the audio, how much has changed, the amount of this change is expressed as a percentage, that is, the degree of distortion. It indicates the degree to which the speaker reduces the input signal.

After the signal is amplified by the audio, it will produce a certain degree of distortion, and the distortion degree is acceptable below 1%, and some audios can achieve the distortion. It's called hi-fi.

The distortion of an audio can be divided into phase distortion and waveform distortion. Phase distortion is inaudible without contrast, and waveform distortion to 5% can be heard by some people. The greater the distortion, the easier it is to hear.

There are many factors that affect the degree of audio distortion,Power amplifier and speaker power matching,Listening to the volume size,Sound source quality, etc.,It is recommended not to just look at the parameters when choosing a speaker,The key is whether you feel comfortable or not,This is the most important thing。

The degree of distortion of a sound is the degree of distortion.

The speaker will not be distorted, the sound distortion is the speaker distortion, the reason for the speaker distortion is because of the magnetic field structure of the speaker, everyone knows that the speaker works by the magnetic field force, from the structural point of view, the magnetic sound structure of the speaker is shown in the figure!

The width of the middle figure represents the strength of the magnetic field, the force of the voice coil is proportional to the magnetic field strength of the stamen, the voice coil moves up and down, the position is different, the force obtained by the voice coil is also different, the longer the voice coil travel, the greater the force difference, this is where the various distortions of the speaker lie, I study the magnetic field countermeasure method, and solve all the problems.

Distortion is one of the effects created by effects, which can be distorted, overdriven, delayed, wah, reverb, phased, and so on.

Generally, you need to use effects to play with an electric guitar (unless you only use the electric guitar to clean the tone, or only use the distortion effect that comes with the speaker, forget to mention, the general speaker comes with a distortion effect channel).

Canon's song uses a lot of effects, the most important of which is distortion, and the others are modified with peripheral effects such as delay.

There is no such thing as a "distortion speaker", it is the speaker that comes with a channel with a distortion effect, and some speakers will also have a spring reverb effect, or other peripheral effects, but most speakers only have a distortion effect.

In general, electric guitar performance is an electric guitar - effects (one or several) - amps, like this.

If you want to change the tone, you need multiple stompboxes, or a synthetic.

The timbre at the beginning of the canon is made with the two effects of distortion + delay, and the timbre that can make the sound stretch for a long time is called delay.

Jerry C Dan Canon uses a mixture of distortion + a variety of effects, and it's hard to say which brand of effect he uses (he hasn't said it himself), but you can buy your own effects to imitate his voice (it's easier to imitate by buying a synthesized effect). The range of heavy metal is too wide, and there are so many heavy metal bands in the world, it can be said that the combination of effects used by guitarists in each band is different. However, generally for heavy metals, it is enough to simply match a distortion and a compression, and the compression can even be omitted.

The monologue has a good timbre and is easy to synthesize. Generally, it is to play the piano a few times, adjust the effect a few times, until the tone is satisfied, if the tone is good, just open the effect and play.

I think your basic knowledge of electric guitar effects and amps is too lacking, and you have already added 3 questions, so it's really troublesome to ask and answer them, so you can text me directly in private.

Acoustic sound distortion may be crossover distortion caused by the transistor operating point is incorrect. If the signal is too strong or too weak, it will be distorted. If the power of the equipment is too small to force the sound to be full, it will also cause distortion, which is clipping distortion and has a DC signal.

In this case, it is difficult for ordinary car owners to distinguish which ones are abnormal noises and which ones are reasonable abnormal noises. Only nearly 20% of the vehicles that went to the repair shop to detect abnormal noises really had problems. Differences between models equipped with turbocharged engines; Models with engine guards may also make noises due to friction; After some car owners come into contact with different cars, it is likely that due to their lack of understanding of mechanical knowledge, they mistake reasonable abnormal noise as a vehicle failure.

Therefore, learn to distinguish the abnormal noise of the car and avoid wasting time and energy.

How to identify the sound of a car:

In practice, due to the limitations of working conditions, it is difficult to measure the sound of the car with special instruments, and the sound of the car can only be described and compared with the judgment of the sound in daily life. For example, the "rattle" sound caused by the dry friction of the bearing, and the "click" sound similar to the small hammer hitting the cement floor caused by the excessive valve clearance.

1. Correctly distinguish between normal and abnormal sounds.

The vibration of each mechanism in the work of the car will emit a variety of sounds, but the sound does not mean that the car is faulty, in order to avoid unnecessary disassembly, we must first distinguish between normal sound and abnormal noise. The normal vibration sound of each system component (such as the noise on the surface of the engine), the impact sound of the gear when shifting, the intake sound and exhaust sound of using gas as the working source, and the noise of gear meshing are all normal sounds. Abnormal noise (abnormal noise) can be divided into slight noise, general noise and malignant noise according to the impact on the performance of the car.

Slight noise, such as the flashover sound of high-voltage electric leakage, the slight loose sound of rolling bearings, etc., the general volume is small, the degree of wear of the parts is not large, and there is no significant change for a long time, and this kind of fault can still maintain the normal operation of the car without repair.

3. When diagnosing abnormal noise, attention should be paid to creating good auscultation conditions and trying to eliminate the interference of other noises, so as not to affect the accuracy of judgment.

It is best to consciously amplify or reduce the sound, that is, use a screw or other metal rod as a stestological instrument to contact the sound part to amplify the sound, or use a single cylinder fire breaker to reduce the sound to meet the needs of diagnosis. The auscultation site should be kept quiet to minimize human interference.
