For the initial understanding of computer speakers, you can use the steps of "viewing, listening, and recognizing" to identify: that is, first view the process and parameters, secondly listen to the sound quality, and thirdly recognize the brand.

A look at the process and parameters

One look at the craftsmanship is to judge the quality of the speaker from the first image on the outside of the speaker, and whether the production process is accurate. Fake and shoddy products generally do not pay attention to these details, so it can be judged correctly with a little care. The technical parameters of computer speakers are nothing more than frequency range, output power, and signal-to-noise ratio.

The frequency range is generally 90Hz~20KHz. 90Hz represents the extension value of the computer speaker in the low frequency direction. The lower the number, the better the low frequency response of the computer speaker: 20KHz represents the high frequency extension value that the computer speaker can achieve. The higher the number , indicating that the audio characteristics are better.

The output power is a reference index of the computer speaker. It is expressed in watts. This indicator does not indicate the quality of the speaker, but only indicates that to drive the power amplifier required for the computer speaker, the battery must have the required output power.

The signal-to-noise ratio refers to the ratio of the voltage of the output signal of the amplifier to the noise voltage output at the same time. It is often expressed in decibels. The higher the signal-to-noise ratio of the device, the less noise it produces. Generally speaking, the larger the signal-to-noise ratio, the smaller the noise mixed in the signal and the higher the sound quality of the sound playback, otherwise the opposite. The signal-to-noise ratio should generally not be lower than 70dB, the signal-to-noise ratio of high-fidelity speakers should reach more than 110dB, and the Z minimum value of the signal-to-noise ratio marked on computer speakers is mostly between 70dB and 90dB.

Second sound quality

Computer speakers are mostly made of plastic materials. The smaller the material density of the speaker shell, the greater the vibration generated by the box when making sound. From this aspect, it is difficult for computer speakers to achieve super bass effect to a certain extent. It is a common problem with all computer speakers. But the so-called extremes meet, although the computer speakers are slightly lacking in bass, the performance of the high-frequency and high-frequency can be done very well. With different design structures and different cavity sizes, the sound quality of computer speakers may still be quite different.

Three recognition brands

Good computer speakers have well-made gold-plated or chrome-plated brand marks. If the trademark has no registration mark, there is no anti-counterfeiting certification mark on the outer packaging, and there is no warranty card inside the packaging, most of these three-no products are suspected of counterfeiting and shoddy.
