Abstract
The invention discloses an infrared bluetooth control sound post. The sound post comprises a box body, a power amplifier and a wireless transceiver. 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; the wireless transceiver is arranged in the box body. The infrared bluetooth control sound post possesses advantages that the sound post works reliably; operation is convenient; work efficiency is high; infrared and bluetooth control is achieved 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 infrared Bluetooth and control 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, and a kind of infrared Bluetooth with advantages such as infrared, Bluetooth control controls sound column.
In order to realize the purpose of the present invention, the present invention is achieved by the following technical solutions: a kind of infrared Bluetooth controls sound column, including casing, power amplifier, infrared receiver, Bluetooth adapter；It is characterized in that: described box house is provided with power amplifier, power amplifier connects organizes megaphone more, and box house is provided with infrared receiver and Bluetooth adapter.
Operation principle: box house is provided with infrared receiver and Bluetooth adapter, and the electric terminal that convenient utilization has infrared receiver and Bluetooth adapter directly controls sound column, for instance: infrared remote controller, mobile phone, panel computer etc..Conveniently use and operate, it is possible to connecting either directly through bluetooth and play out, reduce line arrangement, convenient construction and installation.
The infrared Bluetooth of the present invention controls sound column and has reliable operation, easy to operate, and work efficiency is high, has the advantages such as infrared, Bluetooth control, has significantly high practical value.
Accompanying drawing explanation
Accompanying drawing 1 is present configuration schematic diagram.
In accompanying drawing: 1-casing, 2-megaphone, 3-infrared receiver, 4-Bluetooth adapter.
