Abstract
The utility model discloses a lawn lamp with a light-controlled loudspeaker box. The lawn lamp comprises a lamp post, the loudspeaker box, a light-induction chip used for inducing the intensity of external light, and a single chip electrically connected with the light-inducing chip, wherein the single chip is connected with a variable digital resistor; and the resistance output end of the variable digital resistor is serially connected with the audio circuit of a loudspeaker in the loudspeaker box. The lawn lamp disclosed by the utility model is capable of automatically adjusting volume according to the intensity of external light.
Description
Technical field
The utility model relates to a kind of audio amplifier Lawn lamp, is specifically related to audio amplifier control circuit wherein.
Background technology
The audio amplifier Lawn lamp is the communal facility that audio amplifier and Lawn lamp are combined, and has illumination and music playback function, is widely used in park, residential quarter, the campus, has increased temperament and interest when bringing convenience for people's life.But the music of present audio amplifier Lawn lamp does not possess automatic regulatory function, can not strengthen volume automatically when external environment is noisy by day, can not reduce volume at night automatically when external environment is quiet relatively, and environmental suitability is not strong.
Summary of the invention
At above-mentioned weak point of the prior art, the utility model provides a kind of light-operated audio amplifier Lawn lamp, can be according to the strong and weak automatic regulating volume size of extraneous light.
The technical solution of the utility model is a kind of light-operated audio amplifier Lawn lamp, comprises lamppost and audio amplifier, comprises that also the sensitive chip of responding to extraneous light power reaches and the single-chip microcomputer of its electric connection, and described Single-chip Controlling is connected with the variable number resistor; The resistance output of described variable number resistor is connected in series with the voice band line of loud speaker in the described audio amplifier.
Further, described sensitive chip is OV5116 black and white sensitive chip, and described single-chip microcomputer model is STC89C52; Variable number resistor model is DS3902.
Further, described audio amplifier is located in the lamppost, and described lamppost upper end is provided with the crown top of burner; Described sensitive chip is located on the crown top of burner outer surface.
The beneficial effects of the utility model: the light that sensitive chip can be sensed is strong and weak to be changed, thereby convert light signal to the corresponding signal of telecommunication and export to single-chip microcomputer, single-chip microcomputer is processed into corresponding control signal, the resistance of the variable number resistor that receives this control signal is changed, thereby reach the purpose of control audio amplifier sound size.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is electrical block diagram of the present utility model;
Fig. 2 is external structure schematic diagram of the present utility model.
Embodiment
Further describe the utility model below in conjunction with specific embodiment and accompanying drawing.
A kind of light-operated audio amplifier Lawn lamp as Fig. 1 and shown in Figure 2, comprises lamppost 1 and audio amplifier 2, comprises that also the sensitive chip 4 of responding to extraneous light power reaches and the single-chip microcomputer of its electric connection, and described Single-chip Controlling is connected with the variable number resistor; The resistance output of described variable number resistor is connected in series with the voice band line of loud speaker in the described audio amplifier 2.
From daytime to night ambient noise from diminishing greatly, extraneous light is also from bright deepening; When sensitive chip 4 was sensed light and died down, single-chip microcomputer can change into the signal that receives control variable number resistor resistance and become big control signal, and variable number resistor resistance becomes makes speaker volume reduce greatly.Otherwise when sensitive chip 4 was sensed the light grow, single-chip microcomputer can be controlled variable number resistor resistance and diminish, thereby speaker volume raises.
Further, described sensitive chip 4 is OV5116 black and white sensitive chip, and described single-chip microcomputer model is STC89C52, and variable number resistor model is DS3902.Adopt OV5116 black and white sensitive chip, price is relatively low, and has adapted to the requirement that only needs induction light power to change.
Further, described audio amplifier 2 is located in the lamppost 1, and described lamppost 1 upper end is provided with the crown top of burner 3; Described sensitive chip 4 is located on the crown top of burner 3 outer surfaces.Audio amplifier 2 is located in the lamppost, conserve space, and profile is brief, and plays the effect of protection audio amplifier; The crown top of burner 3 plays the effect of rain and sun, and sensitive chip 4 is located on the crown top of burner 3 outer surfaces can better respond to extraneous light.
More than technical scheme that the utility model embodiment is provided be described in detail, used specific case herein principle and the execution mode of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as restriction of the present utility model.
