Abstract
The utility model provides an illuminating device capable of flashing along with external audio frequency change, relating to the technical field of the illuminating device. The illuminating device comprises an acoustic pick-up used for accepting the external audio signal, a signal amplifying circuit for amplifying the external audio signal, a divider circuit carrying out the frequency division on the amplified circuit, a detection converting circuit for converting the analog signal to the digital signal, a control circuit and an illuminating lamp group which are sequentially connected respectively. After the illuminating device capable of flashing along with external audio frequency change adopts such structure, the external audio signal is collected via the acoustic pick-up; after the external audio signal is amplified, the music signals of different frequency bands are distinguished via the divider circuit; subsequently the music signals are detected via the detector circuit respectively to obtain the electrical signal corresponding to the music rhythm and the amplitude variation of the spectrum component; the electrical signal is input to the control circuit after converted, and the corresponding process is worked out via the microprocessor of the control circuit to control the illuminating effect of the illuminating lamp group to realize the harmonious audio-visual enjoyment having the sense of rhythm and the sense of color of the music.
Description
Technical field:
The utility model relates to the light-emitting device technical field, refers in particular to a kind of light-emitting device that can change flicker with external audio.
Background technology:
Need use light-emitting lamp to come heighten atmosphere or a decoration facility or an indicative function in many occasions.In order to strengthen illumination effect, bulb can be realized the illumination effect of flicker by control circuit.But at present the flicker effect that had of light fixture is to have configured by the control program in the control circuit, and it can't change voluntarily according to actual conditions, for example according to the music rhythm counter point flicker voluntarily at scene.So people wish and the melody and the harmonious rhythm of musical works grace can be mixed harmonious light and color effect, to reach better effect always.
Summary of the invention:
The purpose of this utility model is the deficiency at present product, and a kind of light-emitting device that can change flicker with external audio is provided.
For achieving the above object, the utility model is achieved through the following technical solutions: this light-emitting device comprises and being linked in sequence successively: be used to receive the external audio signal voice input device, with external audio signal amplifying signal amplifying circuit, to the circuit after amplifying carry out frequency division frequency dividing circuit, the circuit behind the frequency division is carried out the detecting circuit of detection and is signaling conversion circuit, control circuit and the electroluminescent lamp group of digital signal with analog signal conversion.
Described frequency dividing circuit will be divided into many group circuit through the audio signal after amplifying by resistance and electric capacity, and these many group circuit are respectively by a detecting circuit entering signal change-over circuit that is made of amplifier and diode.
After the utility model adopts such structure,, such as microphone the external audio signals collecting is come in by voice input device, through after the amplification of amplifying circuit, by frequency dividing circuit the music signal of different frequency range is made a distinction, such as high frequency, intermediate frequency and low frequency etc.Then pass through detecting circuit, obtain the signal of telecommunication with music rhythm and spectrum component amplitude correspondence, by the signaling conversion circuit collection, ratio and variation speed according to each several part, make corresponding processing by the microprocessor of control circuit, control different colours electroluminescent lamp group lamp is such as blink cadence and the brightness of shades of colour LED, to realize the harmonious seeing and hearing enjoyment of musical rhythm and color sense.
