Abstract
The invention discloses a solar wireless sound post. The sound post comprises a vertical rod, the sound post, a solar photovoltaic panel and a storage battery. The sound post is characterized in that a top of the vertical rod is provided with the solar photovoltaic panel; the sound post is arranged in the middle of the vertical rod; a bottom of the vertical rod is connected to the storage battery; a wireless transceiver is arranged in the sound post; the solar photovoltaic panel is connected to the storage battery; and the storage battery is connected to the sound post. The solar wireless sound post possesses advantages that the sound post works reliably; operation is convenient; work efficiency is high; energy saving and environmental protection are achieved; a wireless receiving and sending function is possessed 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 solar energy radio 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 energy-conserving and environment-protective have a kind of solar energy radio sound column of the advantages such as radio transmission-receiving function.
In order to realize the purpose of the present invention, the present invention is achieved by the following technical solutions: a kind of solar energy radio sound column, including vertical rod, sound column, solar energy photovoltaic panel, accumulator；It is characterized in that: described vertical rod top is provided with solar energy photovoltaic panel, be provided with sound column in the middle of described vertical rod, described bottom of upright rod connects accumulator；It is provided with wireless transmitter inside described sound column；Described solar energy photovoltaic panel connects accumulator；Described accumulator connects sound column.
Operation principle: luminous energy is changed into electrical power storage in accumulator by solar energy photovoltaic panel, electric energy is supplied sound column by accumulator, sound column receives the content needing to play, convenient operation and energy-conserving and environment-protective by the wireless transmitter that inside is provided with, it is adaptable to public arena.
The solar energy radio sound column of the present invention has reliable operation, easy to operate, and work efficiency is high, and energy-conserving and environment-protective have the advantages such as radio transmission-receiving function, have significantly high practical value.
Accompanying drawing explanation
Accompanying drawing 1 is present configuration schematic diagram.
In accompanying drawing: 1-vertical rod, 2-sound column, 3-solar energy photovoltaic panel, 4-accumulator.
