Sound speaker sound quality depends on what factors?


The sound quality of the speaker is a key factor affecting the performance of the entire sound system. So, what factors determine the sound quality of the speaker? This article will analyze it in detail.

1. frequency response

The frequency response is the range of frequencies that can be reproduced by the speaker. The wider the frequency response, the more audio information the speaker can reproduce, including low and high frequency sound. Generally speaking, the frequency response range of audio speakers is between 20Hz and 20kHz, but in fact, the frequency response of different models of audio speakers will be different.

2. distortion

Distortion refers to the degree to which the sound output by the acoustic speaker does not match the input audio signal. Distortion can lead to poor sound quality, including harmonic distortion, intermodulation distortion, noise distortion, etc. Harmonic distortion refers to the presence of harmonic components in the sound that were not originally present, which affects the realism of the sound. Intermodulation distortion refers to the cross-modulation effect produced by audio speakers when two or more frequencies of sound are input at the same time, resulting in blurred sound. Noise distortion refers to the presence of random noise in the sound output by the speaker, which affects the clarity of the sound.

3. impedance

Impedance refers to the ability of an acoustic speaker to impede current flow. The lower the impedance, the smaller the resistance of the speaker to the current, and the greater the output sound power. Generally speaking, the impedance of the acoustic speaker is between 4-8 ohms, but there are also higher or lower impedance values.

4. sensitivity

Sensitivity refers to the sound pressure level generated by the audio speaker when inputting an audio signal of a certain power. The higher the sensitivity, the greater the sound produced by the speaker at the same input power. Generally speaking, the sensitivity of the speaker is between 85-110dB.

5. directivity

Directivity refers to the direction and range of sound radiation from the speaker. The stronger the directivity of the speaker, the smaller the range of sound radiation. Generally speaking, the sound radiation range of the omnidirectional speaker is omni-directional, while the sound radiation range of the directional speaker is relatively limited.
