Abstract
The invention discloses a multifunctional 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; connection portions of the box body are provided with shockproof glue mud; a wireless transceiver, an infrared receiver and a bluetooth adapter are arranged in the box body, a MP3 memory is arranged in the box body and the box body is provided with a USB interface; the MP3 memory is connected to the USB interface; a bottom portion of the box body is provided with multiple groups of universal wheels; a side surface and a black side of the box body are provided with detachable connection board devices; the detachable connection board devices are provided with multiple groups of connection fixing holes; and the shockproof glue mud is arranged between the loudspeakers and a box body panel. The multifunctional sound post possesses advantages that the sound post works reliably; operation is convenient; work efficiency is high; functions of wireless receiving and sending, infrared ray and bluetooth control are achieved; the sound post is convenient to move, install and place; the MP3 is arranged and stored in an internal portion of the sound post 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 multi-functional 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 there is simple in construction, reliable operation, the multi-functional sound column of one of the advantages such as easy to operate, work efficiency is high, has wireless receiving and dispatching, and infrared ray, bluetooth manipulate, and are moved easily, install and put, built-in storage MP3.
In order to realize the purpose of the present invention, the present invention is achieved by the following technical solutions: a kind of multi-functional 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；Between described casing, a junction is equipped with shockproof clay；Box house is provided with wireless transceiver, infrared receiver and Bluetooth adapter, and box house is provided with MP3 memorizer, and described casing is provided with USB interface；Described MP3 memorizer connects USB interface；Box bottom is provided with organizes universal wheel more；Body side and the back side are equipped with the plate that removably connects；The described plate that removably connects is provided with many groups and connects fixing hole；Shockproof clay it is provided with between described megaphone and cabinet panel.
Operation principle: sound column of the present invention can pass through wireless transceiver, infrared receiver and Bluetooth adapter various ways and connect and operation, conveniently uses and more safe and reliable；The detachable universal wheel in bottom and removably connect plate with the use of, be moved easily, install and put, increase space availability ratio；Built-in MP3 stores, convenient according to custom interpolation different content.
The advantages such as the multi-functional sound column of the present invention has reliable operation, easy to operate, and work efficiency is high, has wireless receiving and dispatching, and infrared ray, bluetooth manipulate, and are moved easily, install and put, built-in storage MP3, have significantly high practical value.
