There are many kinds of intelligent devices in our daily life. There are a variety of intelligent devices available for consumers to choose. The mini speaker connects USB jack with USB interface. It is favored and recognized by many users. This is due to its advantages of small size and portability. How should consumers choose it when purchasing mini speakers? What mini speaker parameters do we need to know? Let’s take a look at the shopping guide compiled for you.

Most of the mini speakers today are Bluetooth speakers.We will first make some necessary explanations and popular science. This is based on the professional parameter data. We need to pay attention to and understand it when purchasing.

First, frequency response. The larger the frequency response range, the stronger the processing capability for signals. So the audio frequencies contained therein are richer. We should select Bluetooth speakers with large frequency response range. This is under the condition of equal price and only considering frequency response.

Second, distortion. Distortion refers to the change value of the mini speaker. This is after comparing the input signal with the output signal. For Bluetooth mini speakers, distortion is an inevitable phenomenon. But if we can control it within a certain range, it will not have much impact on the sound quality.

Third, impedance. I believe everyone has heard of the concept in their physics study in school. Impedance refers to the ratio of input signal voltage to current. However,the impedance value is not the lower or higher, the better. We should control its value within a certain range. At present, most impedance values are around 8 ohms. This can obtain good sound effects.

However, it is not enough to know some basic components of the mini-speaker. What else should we pay attention to when choosing a suitable mini-speaker?

The first is the cost performance. Cost performance has long been a problem that we must consider when purchasing. Many consumers hope to buy the best products with the best performance within the controllable range. It should be at the most suitable price. Users can make suitable choices among various mini speakers with different characteristics. This is according to their own concerns.

The second is the sound quality. Sound quality is the soul of the sound box. No noise and smooth sensitivity are the characters to consider when choosing the sound box. In addition to the above parameters, if it is a physical store purchase, you can use it first. If it is an e-commerce platform purchase, we can select it according to the comments. In this way, we can draw more objective and specific conclusions.

In addition, we should consider the appearance when purchasing intelligent devices. Major smart equipment brand producers have carried out personalized product design. This is according to various aesthetic needs of consumers. It is best for everyone to choose through their own preferences.
