How to choose a portable loudspeaker? Portable loudspeakers are generally loved by people because of their small size, light weight and portability. Most loudspeakers on the market have different brands and high and low prices. It is easy to make a mistake in the choice. Choosing a suitable and useful loudspeaker has become a big problem. What should we pay attention to when choosing a loudspeaker? Let's have a look
Product parameter function reference
Loudspeaker weight: many loudspeaker products describe compact, lightweight and other properties. In the audio circle, everyone knows that a good sound must be heavy, and heavy does not mean good sound. The better the performance, the more demanding the material selection. In many aspects, in order to ensure the quality of products, the raw materials selected may be heavy, but there are exceptions. For example, the winning e180c portable loudspeaker is relatively light. The main reason is that this speaker is made of rare earth, which is much lighter, but the sound quality and power are still not inferior. Therefore, you need to know the material of the horn when purchasing.
Automatic squealing suppression function: the portable loudspeaker is divided into wired connection and wireless connection, mostly waist hanging type and strap type. The loudspeaker of the loudspeaker is close to the pickup microphone (microphone), which is easy to produce howling feedback (natural phenomenon). In this regard, experienced manufacturers will focus on when designing circuits, which is loud enough and not easy to produce feedback. Many regular manufacturers have the function of automatically suppressing whistling. For example, each winning model has this function, while irregular manufacturers basically do not have this function.
Amplifier power: in order to mislead consumers, many manufacturers in the market falsely mark the power of amplifiers very high, and some even falsely mark it above 30W. For portable amplifiers, the generally reasonable power is in the range of 6-20w, which is normal. For 30W, they are basically portable, so you need to check the power of parameters. Generally, 10W power is enough for a classroom with 40-50 people, and about 18-20w power is required for a large classroom with 100-200 people.
After sales service guarantee
&# 8203;&# 8203;&# 8203;&# 8203;&# 8203;&# 8203; Understand the after-sales service measures and systems in detail. The clearer the description, the more guaranteed it will be. Of course, many distributors exaggerate in order to attract consumers. The one-year warranty of the loudspeaker is said to be two years, and the two-year warranty is said to be three years. Only the product manufacturer is truly and completely capable of maintenance, and only the manufacturer's commitment is more authentic. Generally, the warranty period of electronic products is one year. PS: remember to ask the dealer for the purchase certificate.
Good evaluation basis
Good loudspeaker products can stand the use. Ask friends who have used them or check their experience online to listen to their feelings and ideas. I believe they have high reference value for consumption. A manufacturer who develops products with heart is extremely eager to get word-of-mouth publicity, which is the affirmation and appreciation of hard work.
Appearance experience
A good loudspeaker product will fully consider the use of consumers and meet consumers' demand for appearance on the premise of ensuring product quality as far as possible. R & D products often have contradictions. To weigh the pros and cons, real brand manufacturers will take the quality first. They don't want fancy appearance, but they need to be strong and durable. Taking victory as an example, although the appearance looks simple, ABS material is used, which is firm and wear-resistant.
