Speaker manufacturers teach you how to choose speakers based on speaker parameters

Release time: 2021-09-27    Viewers: 583

No matter what type of speakers, they will have their own parameters, but many people don’t understand when they buy speakers. They can only buy from the speaker manufacturer’s own feelings, but it is not easy to buy suitable speakers. Let the speakers now The manufacturer teaches you how to choose Bluetooth speakers based on the parameters of the speakers.

1. According to the frequency response range.

The human ear can hear the sound frequency range from 20 Hz to 20000 Hz, so speakers with a large frequency response range are better than a small frequency response range, because once distortion occurs, the sound of a speaker with a large frequency response range will still be It is richer and more effective than speakers with a smaller frequency response range.

2. According to impedance.
The lower the impedance of the speaker, the greater the input current, so you should choose a speaker with a large impedance when purchasing. The current common impedances are 4Ω, 6Ω, 8Ω, 16Ω, etc., and 8Ω is the recommended value of the international standard.

3. According to sensitivity.

Sensitivity is a parameter that affects the volume of the speaker. In the case of the same distance, the volume is adjusted the same. The higher the sensitivity of the speaker, the louder the sound without affecting the sound quality. However, the increase in sensitivity will affect the distortion, so it is necessary to choose between the sound quality and the distortion at the time of purchase.

4. According to the signal-to-noise ratio.
The signal-to-noise ratio refers to the ratio of the normal sound signal played back by the speaker to the noise signal when there is no signal. Generally speaking, the larger the signal-to-noise ratio, the smaller the noise mixed in the signal, and the higher the quality of sound playback. The signal-to-noise ratio should generally not be lower than 70dB, and the signal-to-noise ratio of high-fidelity speakers should reach 110dB or more.

5. Distortion degree.
For multimedia speakers, distortion is unavoidable, but if it is within a reasonable range, it will not have much impact on the sound quality of the speakers. The distortion of 2.0 speakers should be below 1%, and the distortion of X.1 series speakers can be below 5%.

6. Rated power.
Power can be divided into rated power and maximum power. However, in order to cater to consumers' psychology, many manufacturers usually mark the power of their speakers very high. Therefore, when purchasing speakers, the rated power shall prevail. The power index does not indicate the quality of the speakers, and it is not that the bigger the better, it only provides a reference for the selection of power amplifiers.
