                                             What are the home theater speakers


As we all know, in a home theater system, there are three main parts, namely the audio part, the video part, the audio and video signal source and various wires.


We can vividly compare it to a person, then the speaker is the mouthpiece of the person, the power amplifier is the brain of the person, the display equipment such as projection is equivalent to the eyes, and various audio and video cables are equivalent to the blood vessels of the person. However, the blood flowing in these vessels is not blood, but audio and video signals.

When it comes to home theater speakers, it has a history of decades. From the way of use, there are ordinary placed speakers, hanging speakers, and embedded (custom-installed) speakers. Ordinary placed speakers also have floor-standing, bookshelf, satellite and other forms, which can be described as varied.

Technically, it can be divided into traditional speakers, electrostatic speakers, flat-panel speakers and other common types. There are also many types of speakers in traditional speakers, such as full-range speakers, tweeters, coaxial (with crossover technology) speakers, etc., while electrostatic speakers must be electrostatic speakers, and there are many kinds of very niche speakers. There are generally two sets of vibrating voice coils under the diaphragm of the flat-panel speaker. The flat-panel speaker has excellent sound quality, with a wide frequency range, low distortion, and good transient response.


From the function, it can be divided into active speakers and passive speakers. Generally, in the home theater audio system, the main box, center and surround speakers are passive. Some subwoofers (subwoofers) are active and some are active. passive. Active speakers, also known as "active speakers", usually refer to speakers with power amplifiers, such as common desktop computer multimedia speakers, and some new home theater active speakers. Passive speakers are also called "passive speakers". Passive speakers are ordinary speakers that we usually use without a power amplifier circuit inside.


From the position or responsibility, it can also be divided into main speakers, center speakers and surround speakers.


The main speaker is the most important pair of speakers in the home theater audio system, responsible for supporting the magnificent scene sound effects of the entire movie. The sound and music accompanying the pictures we see are all emitted from the main speakers; The throat of the theater is generally a speaker, and all the main vocal dialogues in the movie are sent from the center speaker;

The number of surround speakers is variable. For a 5.1-channel home theater, there are 2 surround speakers, and for a 7.1-channel home theater, there are 4. The latest Dolby Atmos technology supports up to 64 channels. How many surround speakers do you think? The role of the surround speakers is to improve the sound enveloping sense of the home theater. The viewers seem to be in the film scene. For example, watching a war movie, you will feel like you are on the battlefield. You can feel the bullets passing by and the shells Exploding around...


The subwoofer (subwoofer) is the ".1" in the 5.1 and 7.1 channels. Needless to say, everyone should also understand that the subwoofer is mainly responsible for the subwoofer channel. How low is the subwoofer? Generally, it is about 200HZ, which means that this low-frequency sound is between the sound and the airflow, similar to the roar, and at the same time, the airflow like the wind can be felt. So what does he do? For example, if you are watching The Hobbit, the giant dragon invades the kingdom of dwarves. When the dragon pushes the city wall, you will feel the shock of the sky and the earth, as if you are standing under the city wall and watching the violent dragon show its power, creating this The sound effects of large scenes such as explosions rely on subwoofers.


The main speakers, center speakers, surround speakers and subwoofers together form the speaker system of the home theater. Of course, with the development of new technologies, the channels are constantly increasing, but the changes are inseparable from the original, and they are all inseparable from this framework. . By understanding the principles of speakers and channels, we can better guide us to build a home theater system and enjoy high-quality audio and video entertainment.
