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

 Reasons for speaker distortion:

1. Overload distortion: When the input signal is too large, the speaker is unable to effectively convert the signal into sound, resulting in distortion. This kind of distortion usually occurs when the volume is too high. 2.

2. non-linear distortion: the vibration system of the speaker is not completely linear, when the input signal frequency is high or amplitude is large, the response of the vibration system may become non-linear, resulting in distortion.

3. harmonic distortion: when the harmonic frequencies generated by the horn during vibration do not match the original signal frequency, harmonic distortion will occur, making the sound become distorted.

4. Mechanical distortion: Problems with the speaker diaphragm or mechanical components of the vibration system, such as aging, deformation, or loosening, can lead to sound distortion.

Distortion performance:

1. harmonic distortion: the presence of frequency components in the sound that do not belong to the original signal, making the sound sound sound sharp or distorted.

2. intermodulation distortion: different frequencies of the sound mixed together, resulting in new frequency components, so that the sound sounds cluttered.

3. intermodulation distortion: the interaction of different frequencies of sound to produce new frequency components, so that the sound becomes chaotic and distorted. 4. shear distortion: the sound of waveforms to produce new frequency components.

4. Shear distortion: The top and bottom of the sound waveform are cut off or distorted, making the sound sound distorted and unnatural. 5. Compression distortion: The top and bottom of the sound waveform are cut off or distorted, making the sound distorted and unnatural.

5. Compression distortion: the dynamic range of the sound is compressed, so that the sound sounds flat and powerless, losing the vivid sense of music and expression.

In summary, the speaker distortion for a variety of reasons, including overload distortion, non-linear distortion, harmonic distortion and mechanical distortion. These distortions will be manifested in the sound of distortion, clutter, shear, compression and other characteristics, affecting the sense of hearing and sound quality. Therefore, when designing and using loudspeakers, attention needs to be paid to the control of signal inputs, linearity of vibration systems and maintenance of mechanical components in order to reduce distortion and improve sound quality.
