The speakers aim to play sounds through an electroacoustic transducer, where electric waves are converted into mechanical energy, which then becomes acoustic frequency waves. Once this is done, the sound is gradually transmitted through the air so that they finally reach the ears of the receiver. It will be in this part of the body where these waves are captured that will then be transformed into nerve impulses that reach the brain, which it finally interprets as voices, sound, and music.You may have found a lot of portable speakers sold at Shoppok.com but can?t decide what to buy so in this article, we are going to educate you more about the speakers to help you decide what to buy. Let see Portable Speakers Choosing the Best.
Main features of portable speakers
First, let’s delve into the different features that can be found on the speaker user manuals in general. In this way, we are sure that you will be able to better understand how they work:
1. Frequency response
This value relates to the quality of the sound that reaches the human ear. It is measured at different audio frequency levels (from 20 to 20,000Hz). In this sense, the higher the frequency response, the higher the quality of the final sound. Because this value is not completely flat, the response will not be the same in bass or treble sounds. For this reason, it is very important that there is the slightest difference in sound (in decibels) to avoid distortions.
This feature is related to the amount of electrical power that the speakers are able to withstand. It has nothing to do with acoustic power and is always measured in watts. If the speaker receives too much “power”, it may be damaged or the sound may become distorted. It should be noted that there are two types of power:
- Nominal power. This is the amount of “maximum” power that the speaker can withstand before it deteriorates. Otherwise, it can be permanently damaged, as the peripheral is not able to dissipate heat produced by the electric current.
- Allowable power. This consists of signal spikes that can support speakers in short spaces of time, just before the diaphragm inside the coil deteriorates.
Impedance is a value that is measured in ohms and has to do with the “opposition” that the sound has when it comes to passing through an alternating current. In the case of speakers, the impedance varies depending on the frequency and therefore also the speaker model. One way or another, if you want to get the most power transfer between the sound source (the amplifier) and the speaker, the impedances between the two components should be as similar as possible.
Sensitivity measures nothing more and nothing less than the relationship between the electrical level of the speaker input and the sound pressure obtained by the sound produced. It is always measured in DB/W one meter away and applying 1W power directly to the speaker.
The degree of sensitivity of the speaker is measured here. This is a value that determines the relationship between the radiated acoustic power and the electrical power that comes from the input. If speaker performance is low, 1-5% is understood. That is, if you enter for example 100W, they always come out 1-5W.
The speaker can be considered as one of the most distorting audio systems because there are all kinds of elements that cause it, such as partial vibrations, or air gap flow. Much of the distortion is usually given in bass sounds.
This value determines the direction of sound right from the moment you exit the speaker. That is, the way it is distorted when it reaches the environment. From there, the direction of sound can be divided into three: omnidirectional (the sound rate at 360o), bidirectional (sound travels in the form of eight, symmetrically), and unidirectional (sound goes in a very marked direction and is therefore very quiet)
Different types of portable speakers
Having analyzed in depth the main characteristics of the speakers, we do not need to tell you that these are an essential peripheral when it comes to playing any content and thus getting the right environment when playing any video game or watching a movie or series.
However, due to the different types of speakers that exist, there are many users who are somewhat lost when choosing the best one that suits their pockets and needs. Are you one of them? If yes, there is nothing to worry about, because through the following lines we will take a tour of the different types that exist:
1. Shelf speakers
Shelf speakers are an option to consider for those who are looking for remarkable features at a fairly contained price. This type is characterized by two speakers, one of them for treble and one for bass. They have a small size and a pretty decent 2.1 sound quality.
2. Floor speakers
Floor speakers, unlike shelf speakers, are characterized by much larger dimensions. They can hold several speakers next to a couple of tweeters, which are precisely responsible for playing the high-pitched sounds, as well as a subwoofer. They are the most used to play music or videos.
3. Speakers 5.1
5.1 speakers have become a widespread option for all users who have a multitasking PC while looking for remarkable sound quality without further pretensions. They are usually made up of four speakers (two sides, two rears, and the subwoofer). Prices are usually very low, as we can find them from 30-40o to 400o.
4. Speakers 7.1
If you are looking for the best sound quality without looking at the price so much, then you can not lose sight of the 7.1 speakers. They consist of a computer that is capable of supporting Dolby TrueHD and DTS-HD sound quality. Although as we have already told you, they offer excellent sound quality and are therefore an option to take into account for those who want to set up a home-cinema at home.
With the rise of Smart TVs in general, many users are looking for speakers that can be installed easily and without having to take up too much space in the living room. For all of them, there are the soundbars, a fairly economical option that also offers excellent sound quality since many times come even with 7.1 sound.
6. Wireless speakers
More and more people are opting for wireless speakers when playing music or videos in the form of movies or series. Needless to say, they are very simple and convenient to use as they do not need any type of cable and also offer more and more sound quality that is very similar to analog.
Now that you know the types and features of different portable speakers, you should not have a problem choosing the best speaker to buy at Shoppok.com.
