Technical field
The present invention relates to the arrangement method of audio amplifier, and in particular to a kind of arrangement method of sound-channel voice box.
Background technology
Reform the growth of for decades economic smooth sequential with China, all lived in one, two, the three many families in line city
Low-density is entered and has had the villa in more spaces, quality of the life has also been improved therewith.So having independent audiovisual studio in villa, being good for
Body room, mini bars, billiard parlor etc. possess the room of various functions, therefore generate the acoustics topic of cubicle.Daily
Functional contact all has realized that a necessity for independent audiovisual studio in villa to many villa owners, because to one's name
Excellent vision and sense of hearing grand banquet can be enjoyed in independent audiovisual studio, is limited without by Movie show times herein,
Cubicle sound-channel voice box pendulum position standard is always that audio-visual industry practitioner is discussing the problem with concern, how could be calculated
Go out the rational putting position of cubicle sound-channel voice box and any time, anyone is not subject in this independent space
Interference so as to enjoy, do not go out door can enjoy see a film, listen music, sing enjoyment.
The content of the invention
It is an object of the invention to：A kind of method for putting sound-channel voice box, the multichannel put using this method are provided
Audio amplifier, can not be capable of achieving door can enjoy see a film, listen music, sing enjoyment.
A kind of method for putting sound-channel voice box is provided, the audio amplifier is divided into：Left and right main sound box, center-channel speaker, right and left rings
Center-channel speaker, the preposition left and right audio amplifier in top, the rearmounted left and right audio amplifier in top, subwoofer behind audio amplifier, left and right, arrangement method are as follows：
The distance that left, center, right main sound box is put determines according to projection screen width, the distance between left and right, main sound box many
In 2.5 meters, center-channel speaker should be in the position of projection screen median line, the height that left, center, right main sound box is put=room height *
0.618；
The position of left and right surround speaker=room length * 0.618, the height that left and right surround speaker is put=room height * 0.618；
The position of center-channel speaker behind left and right=room width * 0.618, height=room height that center-channel speaker is put behind left and right divided by
* 0.618 after 2；
Position=main sound box and the surround speaker distance of the preposition left and right audio amplifier in top, room width * 0.618.
Center-channel speaker distance, room width * 0.618 after the position=surround speaker of the rearmounted left and right audio amplifier in top and left and right；
Subwoofer position is placed in the ground below the screen left side or the right using point sound source mode side by side.
It is the villa of triple layer with basement in agent structure, one layer is parlor, this space phase for doing audiovisual studio of kitchen
To less；Two layers, three layers is study and bedroom is principal bedroom, but because most of villas are between building ripe buildings in
If away from not far insulation works（Sound insulation is the maximum and time-consuming operation of an infusion of financial resources）Treatment is bad to cause serious shadow
Ring, so basement is the optimal selection for doing audiovisual studio, here due to being closed space and reinforced concrete structure sound insulation
Relatively preferably, more resources can are put into terms of audio-visual equipment, so that effect on sound insulation without an input huge sum of money
More preferably.
By the fund input for selecting the room of rational space proportion to save on Acoustic treatment, what is to close
The space proportion of reason, general rectangle room is relatively how also more more satisfactory.But also there are square platform, circular irregular room
Between the treatment of this type room acoustics it is most complicated, the reflection of square room sound wave border is serious easily to produce sound knot picture fuzzy and not
Natural tone color, the room of circular and irregular shape is wavy because the reflected sound of room boundaries repeatedly forms density with direct sound wave
It is easier flutter echo occur after state, the serious sound for having obvious father-in-law father-in-law.
Understanding and treatment to room boundaries reflection：
Being overlapped mutually in listening zone in above-mentioned cubicle direct sound wave and reflected sound can cause sound knot picture fuzzy and destruction tone color
The sense of equilibrium, sound wave pass through the parallel wall in both sides（Reinforced concrete structure）Form first reflection, the second secondary reflection even many
Secondary reflection forms reverberation sound and time delay sound, so as to cause the reverberation time to substantially exceed the rational scope of cubicle（0.3-0.5ms is
The cubicle preferable reverberation time）
Treatment to border reflection problems, method mirror image test find out both sides wall first reflection sound area domain with 5 centimetres with
On polyester fiber sound-absorbing material carry out intensity absorb medium-high frequency treatment because influence of the first reflection ripple to direct sound wave is most
Greatly.On screen opposite, serious reflected sound region metope diffusion structure is processed and makes reflected sound distributing equilibrium.Other metopes do gently
The sound-absorbing treatment of degree, is also good sound-absorbing material with bookshelf, abundant cloth, skin furniture.
Echo is that multiple reflections cause bright drone sound between two pieces of parallel metopes, it is this drone can be directly entered me
Ear, uneasy and irritated so as to make us feeling, villa audiovisual studio is trembled echo relatively benefit reason, can be in the parallel of room
Two metopes have made 20 pieces of sound-absorbing components（Thickness 5CM）With diffusion cylinder（Thickness 12CM）, spacing during installation between component is
10CM, does rough decorative model solve problem respectively.
Stationary Wave clearly and easily occurs, and the medium-high frequency of standing wave is according to the computing formula λ of wavelength=C/f, ripple
The sound-absorbing component that length has 20 pieces of 5CM thick processes basic solution.The generation of this villa cubicle standing wave in 30Hz-125Hz frequently
Rate scope, causes Frequency to respond sound quality and impulsive force uneven, that have a strong impact on low frequency, can more cause each seat
On low-frequency effect it is different, occur there is the relatively low point of relative low-frequency sound pressure and higher point on frequency test figure（Peak and valley shows
As）
The solution of villa audiovisual studio standing wave, early stage has the length or width way for changing room, and the later stage is used in smallpox
Surrounding hollow out width（60CM* height 25CM）50 kilograms of acoustical cotton of filling, both sides wall do in the middle of 10 cylinders hollow outs and
As bass trap below the back side wall at seat, also select reasonably to be put using many subwoofers and selection subwoofer
The several method of position.
The treatment of resonance
Low frequency signal easilys lead to the resonance of object in room, and acoustic assembly or unstable mechanical connection are also easily triggered
The resonance of the built-in ornaments in room, light fixture, furniture and other items.This sound sounds like loudspeaker rupture or amplifier damage is produced
Raw distortion, the effect of severe jamming audiovisual studio views and admires experience.Solution early stage has as far as possible hard using damping keel and reduction
Property connection；Later stage solution:Play whether slow swept-frequency signal hears have resonance sound from 20Hz-1KHz frequency ears,
Find out reason and with tamping and felt solve problem.
A, the sound insulation for door
Method one, around audiovisual studio doorframe encrypt strip of paper used for sealing after, civilian sound insulation steel casement door is thickeied using " sound lock formula ".
Strip of paper used for sealing being encrypted around method two, thickening wall and doorframe and using inside and outside twice door, 5 are filled in door body cavity
Centimetre soft acoustical cotton.
B, the sound insulation for light inlet window
Method one, direct brick wall are blocked, the method best results.By illuminating and lighting and Jing Yin VMC can be installed.
Method two, reservation light inlet window, increase plug-type wallboard together when being made using civilian sound control glass.
C, air-conditioning system can prevent sound from thus blazing abroad using zigzag sound insulation pipeline.
D, the hole that pipeline is blocked using gap-filling glue and encapsulant.
E, smallpox and four sides wall use damping keel, reduce the vibrations of wall.
5 kinds of ways of the above all ensure more than the DB of sound transmission loss 60, and room noise checks and accepts (38 below DB) up to standard, outdoor noise
Check and accept (35 below DB) up to standard.
By the treatment of above-mentioned committed step, the acoustic enviroment of villa audiovisual studio is substantially up to standard, and reverberation time control exists
0.4-0.6s scopes, in below 40DB, villa owner also buys sound appliances can just regarded criteria for noise without stepping door
Listen room experience heartily depending on, listen, sing the brand-new enjoyment for being brought.
