Abstract
The invention discloses a shockproof and anti-interference sound post. The sound post comprises a box body, a power amplifier and loudspeakers. The sound post is characterized in that the power amplifier is arranged in the box body, the power amplifier is connected to multiple groups of loudspeakers and the loudspeakers are arranged on a front side panel of the box body; shockproof glue mud is arranged between the loudspeakers and a box body panel; and connection portions of the box body are provided with the shockproof glue mud. The shockproof and anti-interference sound post possesses advantages that the sound post works reliably; operation is convenient; work efficiency is high; the sound post has shockproof and anti-interference functions and so on. The sound post possesses a high practical value.
Description
Technical field
The present invention relates to a kind of sound column, particularly relate to a kind of shockproof anti-interference sound column.
Background technology
So-called sound column is arranged into an array generally more than 2 speakers, produces plane sound field, listens in scope certain, and the attenuation ratio point sound source of sound is much lower.Such as 5M listen to distance, point sound source has about been decayed 14dB, and the sound column being designed to its decay only 7 dB, it then follows be the gap of a times, therefore the more remote gap of distance is more obvious.Certainly, this is also intended to drop in the effective range of the flat field of sound column to be only and reaches.Concrete data please browse the books of some acoustic connections.Such benefit is exactly listen in distance certain, and the ratio of direct sound wave is well beyond reflected sound (in other words ambient sound), and so, the impact of audition just can be greatly reduced (medium-high frequency part) by room or environment.
Owing to sound column speaker is many, unless custom-designed high impedance speaker, generally will not all speaker in parallel (such total impedance is too low, electric current is excessive, easily make power amplifier close to short-circuit, overload heating even damage) all series connection also improper (such total impedance is excessive, and power amplifier cannot drive) thus should also, string combines, it is desirable to make impedance between 4-8 Ω (because the load of general power amplifier is all between 4-8 Ω).The sound column design of higher level is by the packet between different speakers and frequency dividing, it is possible to reach better frequency response and coverage.
At present, the sound column on market is based on the principle of audio amplifier more increases the acoustical quality that simple circuit composition is good, functional single, it is impossible to meet the market demand.
Summary of the invention
It is an object of the invention to provide one and have simple in construction, reliable operation, easy to operate, work efficiency is high, has the shockproof anti-interference sound column of one of the advantages such as shockproof anti-interference function.
In order to realize the purpose of the present invention, the present invention is achieved by the following technical solutions: a kind of shockproof anti-interference sound column, including casing, power amplifier, megaphone;It is characterized in that: described box house is provided with power amplifier, power amplifier connects organizes megaphone more, and described megaphone is located on casing front panel, is provided with shockproof clay between described megaphone and cabinet panel;Between described casing, a junction is equipped with shockproof clay.
Operation principle: shockproof clay is added in each junction of casing, reducing sound column is the resonance produced in work, eliminates mechanicalness noise, purifies tonequality volume;And pronunciation vibrations can significantly be declined by the shockproof clay between megaphone and cabinet panel, reduce power amplifier unofficial biography vibration frequency simultaneously, effectively reduce mechanicalness noise and impurity.
The shockproof anti-interference sound column of the present invention has reliable operation, easy to operate, and work efficiency is high, has the advantages such as shockproof anti-interference function, has significantly high practical value.
Accompanying drawing explanation
Accompanying drawing 1 is present configuration schematic diagram.
In accompanying drawing: 1-casing, 2-megaphone, the shockproof clay of 3-.
Detailed description of the invention:
Embodiment 1
A kind of shockproof anti-interference sound column, including casing 1, power amplifier, megaphone 2;It is characterized in that: described casing 1 is internal is provided with power amplifier, power amplifier connects many group megaphones 2, and described megaphone 2 is located on casing 1 front panel, is provided with shockproof clay 3 between described megaphone 2 and casing 1 panel;Between described casing 1, a junction is equipped with shockproof clay 3.
Embodiment 2
Operation principle of the present invention: shockproof clay 3 is added in each junction of casing 1, reducing sound column is the resonance produced in work, eliminates mechanicalness noise, purifies tonequality volume;And pronunciation vibrations can significantly be declined by the shockproof clay 3 between megaphone 2 and casing 1 panel, reduce power amplifier unofficial biography vibration frequency simultaneously, effectively reduce mechanicalness noise and impurity.
