Abstract
The invention discloses a sound post convenient to be suspended and installed. The sound post comprises a box body and a power amplifier. 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; a side surface and a back surface of the box body are provided with connection board devices; and the connection board devices are provided with multiple groups of connection fixing holes. The sound post convenient to be suspended and installed possesses advantages that the sound post works reliably; operation is convenient; work efficiency is high; the sound post is suitable for being installed in different environments 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 convenient sound column hanging installation.
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, is suitable for a kind of convenient of the advantages such as varying environment installation and hangs the sound column installed.
In order to realize the purpose of the present invention, the present invention is achieved by the following technical solutions: a kind of convenient sound column hanging installation, including casing, power amplifier；It is characterized in that: described box house is provided with power amplifier, power amplifier connection is organized megaphone, body side and the back side more and is equipped with attaching plate elements；Described attaching plate elements is provided with many groups and connects fixing hole.
Installation method: box side and backboard are equipped with attaching plate elements, attaching plate elements is a kind of external additional structure, is easy for installation and removal, and can relatively select the mounting structure being suitable for according to different environment, it is easily installed in applicable position, builds good tonequality and environment.
The convenient sound column installed that hangs of the present invention has reliable operation, and easy to operate, work efficiency is high, is suitable for the advantages such as varying environment installation, has significantly high practical value.
Accompanying drawing explanation
Accompanying drawing 1 is present configuration schematic diagram.
In accompanying drawing: 1-casing, 2-megaphone, 3-attaching plate elements.
