What are the causes of speaker distortion, and how many of these distortions are there?

Loudspeaker distortion refers to the aberration or distortion between the output signal and the input signal during the amplification and output of the audio signal. Speaker distortion is caused by a variety of reasons, including the following:

1. non-linear distortion: non-linear distortion is the most common form of speaker distortion. When the speaker works at high volume, the diaphragm will appear nonlinear deformation, resulting in a difference between the output signal and the input signal. This distortion is manifested in the sound distortion, become rough, sound quality degradation.

2. harmonic distortion: harmonic distortion refers to the audio signal amplification process, the output signal appears in the original signal frequency of an integer multiple frequency components. This kind of distortion will make the sound sound sharper and sharper, affecting the clarity and authenticity of the sound quality.

3. Crossover distortion: Crossover distortion refers to when the speaker's multiple drive units (such as bass units and tweeters) work in the same frequency range, due to mutual interference or phase differences and other reasons, resulting in abnormal changes in the output signal. This distortion will make the sound sound confusing and unclear, affecting the accuracy of the sound quality.

4. Phase distortion: Phase distortion refers to the change in the phase relationship between different frequency components in the output signal, resulting in time misalignment or phase misalignment of the sound in the propagation process. This distortion will make the sound sound fuzzy and incoherent.

5. Frequency response distortion: frequency response distortion refers to the speaker at different frequencies under the output sound pressure level is not consistent, resulting in unbalanced performance of the sound at different frequencies. This distortion will make the sound sound distorted and unnatural.

6. Temperature distortion: Temperature distortion refers to the high power drive, the internal components of the speaker because of the temperature rise and lead to performance degradation, resulting in distortion. This distortion will make the sound sound dark and fuzzy. 

7. Peak distortion: Peak distortion refers to transient spikes in the audio signal, resulting in the speaker in the processing of these spikes signal distortion phenomenon. This distortion will make the sound sound sharp, harsh. 8.

8. Compression distortion: compression distortion is when the dynamic range of the audio signal exceeds the speaker's range, the speaker can not fully restore the dynamic range of the original signal, resulting in the signal is compressed, the distortion is serious. This distortion will make the sound sound distorted, lack of dynamics.

Horn distortion manifests itself in various forms, mainly including sound distortion, sharp, rough, chaotic, unclear, incoherent and so on. In order to reduce the speaker distortion, you can take the following measures:

1. choose better quality speaker products, avoid buying low-quality products.

2. control volume moderately, avoid long time high volume use.

3. Regularly service and maintain the speaker equipment to ensure its normal operation. 4.

4. Avoid using the speakers in a too high or too low temperature environment to reduce the occurrence of temperature distortion.

5. Use appropriate audio sources and audio equipment to ensure signal quality.

6. Place and adjust the speakers correctly to ensure their best working condition.

Through the above measures, you can effectively reduce the speaker distortion, improve the sound quality performance, so that the sound is more clear and true.
