LED is filled in described LED seat 4.
The workflow of magnetic fluid music box is as follows:
(1)External power source is powered for magnetic fluid music box by USB power source interface 12 or 5VDC jack 8;
(2)The audio signal that the signal input part receipt signal source of audio-frequency power amplifier 6 provides, audio-frequency power amplifier 6 are transferred to speaker 5, electric magnet 3, LED by after the audio signal receiving amplification;
(3)Electric magnet 3 produce with audio signal change magnetic field, magnetic fluid change magnetic field in produce tufted decorative pattern, Decorative pattern rotational deformation, the morphology change of drop vibrations, realize the melody " dancing " with music for the magnetic fluid;Meanwhile, in LED seat 4 LED coordinate the synchronous music play in speaker 5 to produce dynamic light effect.
Described signal source is one of following four:1. the audio file in SD card;2. the audio frequency letter that microphone provides Number;3. the audio signal of tone frequency channel wire transmission;4. the audio signal that signal generator provides;
Audio file in described SD card passes to audio-frequency power amplifier 6 after audio decoder;
The audio signal of described tone frequency channel wire transmission is the audio signal being imported by mobile phone or computer.
Described button 10 includes controlling the A button of audio file switching in SD card;The there is provided audio signal of microphone is provided The B button of gain amplifier;Regulate signal generator input signal strength and the C button of frequency;Adjust speaker 5 volume and magnetic current The D button of body exercise intensity.
Magnetic fluid music box passes through additional electromagnetic field, magnetic fluid is manipulated so as to be changed pattern, both had and view and admire Property, there are extremely strong physics demonstration and science popularization bandwagon effect again, the direct feel to magnetic fluid and magnetic signature for the experimenter can be deepened And understanding, improve their study and the interest of research, as artistic exhibit, physics demonstration experiment instrument or magnetic current bulk properties Science popularization show instrument, its demonstrative process innervation is interesting, has stronger teaching and ornamental value.
