Product Description

One, according to the use of occasions to points: divided into two major categories of professional speakers and home speakers
Home speakers are generally used for playback on family and its characteristics is playback quality is fine and smooth and soft,

more sophisticated appearance, beautiful, playback of sound pressure level is not too high, under the power of relatively less.

Professional speakers generally used for dance hall, Cara OK, theaters, halls and stadiums and other professional entertainment.

General professional speakers is of high sensitivity, high playback sound pressure, good strength, bear power, compared with the

 home speakers, the sound quality is too hard, appearance is not very delicate. But in the professional speakers in the monitor

speakers, the performance and home speakers are more close, the general appearance is also more refined, compact, so this type 

of monitor speakers are often used by the home HI-FI audio system.




Home speakers are mainly divided into two categories: one is the ordinary type of speakers. Its quality in general, only in small volume in the

common room use, not suitable for enthusiasts to use, not for ballroom and other occasions.
Another kind is the speaker HiFI, which most of the high-grade hi-end speakers with pursuit of the perfect sound effect, and spared no expense 

in the production, and even the use of gold of row wiring column, some of the price up to hundreds of thousands of yuan. Hi-END speakers for the 

mid-range of the most varieties of a class, this class of Hi-END features is the use of the production of new technology, the shape of the box

body is ever-changing, power to withstand large, sound field listening effect is good.

Two, according to the audio rate to points: can be divided into full band speakers, bass speakers and super bass sound box


The so-called full band speaker refers to cover low frequency, intermediate frequency and high frequency range of audio playback. The lower limit

frequency of the whole frequency band is 30Hz-60Hz, and the upper limit frequency is 15KHz-20KHz. In general only a small sound system or two pairs 

of full band speakers can fully carry playback task. Bass speakers and subwoofer speakers are generally used to supplement the special low frequency

full band sound and ultra low frequency playback. This sound box is generally used in large and medium-sized, sound system, to strengthen the sense

of shock and low frequency playback. When used, most of the frequency divider (divider), the low frequency signal into a special bass amplifier, 

and then promote the bass or bass sound box.

Three, according to the purpose: generally can be divided into the main speakers, speakers and playback feedback speaker etc.

The main speakers are generally used as the main speaker audio playback system, undertake the main task of playback. Performance of main playback 
speaker playback quality of the sound system of the impact is very big, also can choose to use a full band speakers and SUBWOOFER SPEAKER playback combination.
The monitors for control room, the recording room used for program monitoring, it has small frequency response, wide and flat, the signal with little
modification, so most can realistically reproduce the show the original features of the distortion.
Back to listen to the sound box is also known as the stage monitor speakers, usually used in the arena or dance hall for actors or musicians or band 
members listen to their singing or playing voice. This is because they are located on the stage the main playback speaker behind, can not hear clearly 
their sound or a band playing. Therefore, it cannot be well with or can not find the feeling, seriously affects the performance effect. General return 
to listen to the sound box made of inclined plane shape and placed on the ground, this can on stage by stage of the overall modelling, and during playback 
to stage people listen to clear, is not sound feedback to the microphone and cause howling.
Four, according to the box structure to points: can be divided into the sealed box, the inverted phase speaker, the maze type sound box, acoustic tube type 
sound box and multi cavity resonator type sound box, etc.
Which is the most widely used in professional speaker phase inverted type loudspeaker and its characteristics is a wide frequency response, high efficiency,
high sound pressure, in line with the professional audio speaker system type, but because of its lower efficiency, so in the professional speakers seldom used,
mainly for household speakers, only a small number of monitors the closed box structure. Seal type sound box has the advantages of simple design debugging,
wide frequency response, low frequency transient characteristics good, but to dial voice unit has a higher request. At present, in a variety of speakers, 
the inverted phase speaker and the sealing type speaker accounts for most of the proportion of other types of speakers of a wide variety of structures,
but the proportion of very few.In fact, they are called the inverted phase type box, low frequency radiation type speakers, is the system in the sound box 
to open a slot (slot) of a class of speakers. Because of the opening of the hole, the sound of the box can radiate to the outside. The inverted phase sound
box is also known as the low frequency radiation sound box, which is also the most commonly used box in the multimedia speakers. It is different from the
confined type of speakers, the sound box of the front design of the cylinder shaped hole, in order to make the air circulation inside and outside the box,
it has a higher power and lower distortion than the box, the amount of high sensitivity, high sensitivity, both for the general family, can also be used 

in the lobby or professional.
