Fig. 2 is the schematic representation of apparatus that can rotate with sound according to another preferential embodiment of the utility model, and its base portion is a broken section.
Fig. 3 is according to the phonetic analysis unit of the preferential embodiment of the utility model and motor-drive circuit schematic diagram.
Embodiment
Collection sound equipment in the utility model is can collected sound signal and be converted into the device of electric signal, and the commonly used but collection sound equipment that is not limited to is just like acoustic pickup, microphone etc.Employed motor wants to realize the angular displacement size of speed governing and control rotation in the utility model, can select stepper motor for use, also the mode that can adopt common electric machine to combine with position transducer.
With reference to figure 1, a kind ofly can comprise acoustic pickup 1, phonetic analysis circuit 2, motor-drive circuit 3, stepper motor 4, base 5 and rotating disk 6 with the device that sound rotates.Wherein, acoustic pickup 1 links to each other with the input end of phonetic analysis circuit 2, the output terminal of phonetic analysis circuit 2 links to each other with the input end of motor-drive circuit 3, the output terminal of motor-drive circuit 3 links to each other with stepper motor 4, stepper motor 4 is fixed on the base 5, and an end of the rotating shaft of stepper motor 4 is fixedlyed connected with rotating disk 6.
Also can be provided with on the rotating disk 6 and fixedly put the device of article thereon, as location pit, magnet, screw thread, spring clamp, VELCRO etc. are set, the article that are placed on the rotating disk 6 when guaranteeing rotating disk 6 with running of any angle of inclination and high speed rotating do not fall.
Also can be provided with translucent cover on the rotating disk 6, translucent cover can be fixed on the rotating disk or be fixed on the base, but and the translucent cover folding to put into or to take out article, both can see the article that are placed on the rotating disk 6 thus, can prevent that again article from falling in rotating disk 6 rotary courses.
With reference to figure 3, phonetic analysis circuit 2 comprises RL-C filter unit, operational amplification circuit A, single-chip microprocessor MCU, keyboard KEYBOARD and display DISPLAY, its annexation is: RL-C filter unit output terminal is connected with operational amplification circuit A input end, operational amplification circuit A output terminal links to each other with the single-chip microprocessor MCU input end, keyboard KEYBOARD links to each other with the MCU input end, and display DISPLAY links to each other with the MCU output terminal.Operational amplification circuit A can adopt as LM324 operational amplifier etc.Single-chip microprocessor MCU is the single-chip microcomputer with mould/number (A/D) translation function, can adopt the LPC2132 as PHILIPS.LPC2132 has 16 A/D, and has 60MHZ ARM CPU to perform an analysis to calculate and Electric Machine Control.Motor-drive circuit 3 comprises motor drive ic, and the input end of motor drive ic links to each other with the output terminal of single-chip microprocessor MCU, and the output terminal of motor drive ic links to each other with stepper motor 4.Selecting for use by the watt level of stepper motor of motor drive ic decided, and for low-power machine, wherein four groups of circuits of available ULN2003A promote one four phase motor, and exporting every phase current is 500mA.The course of work of phonetic analysis circuit 2 and motor-drive circuit 3 is: the sound signal that acoustic pickup 1 collects is amplified through RL-C filter unit and A, become tens thousand of samples of signal of per second by single-chip microprocessor MCU through A/D converter, calculate sound characteristic through embedded software again, calculate stepper motor 4 required rotating speed or angles, export stepper motor 4 control signals again, but be enlarged into the electric power of pushing motor by motor drive ic.From parameters such as keyboard KEYBOARD selectively actuatable pattern, reaction ratio and speed.But display DISPLAY modes of display operation data and sound characteristic.
Stepper motor 4 can combine with position transducer to substitute with common electric machine, and correspondingly circuit is suitably adjusted.
When using, on rotating disk 6, place article, can place any article,, also can place favourite article of user such as cartoon toy, exquisite souvenir or the like if energy is luminous, reflective or other optical effect is better as indicant.Adjust acoustic pickup 1 position to gather sound, phonetic analysis circuit 2 calculates some characteristic of the sound that acoustic pickup 1 collects, as volume or tone, calculate due rotating disk angle or rotating speed according to its value again, meet the requirements of angle or rotating speed by motor-drive circuit 3 control step motors 4 then.
For example, be the characteristic that benchmark calculates sound with at that time volume with respect to former 5 seconds average volume, with per 3 decibels with respect to rotating disk 1 the rotating speeds of 5 circles.5 seconds high 30 decibels sound of average volume of a ratio can make rotating disk rotate with the speed of 2 circle/seconds along clockwise direction.Hang down 60 decibels as volume than 5 seconds average volume, just rotating disk rotates in the counterclockwise direction with the speed of 4 circle/seconds.The user watches the action that is placed on the article on the rotating disk 6 just can experience the variation of volume.
For another example, represent the tone of keynote with the position, every semitone is with 1/12 circle representative, and the direction of rotating disk just has direct relation with tone, and each circle is equivalent to through an octave.Place a laser apparatus on rotating disk 6 as the user, rotating disk 6 just can accurately show the tone of keynote at that time.Song if any the people is collected by acoustic pickup 1, just radium-shine angle is corresponding with its tone, compares again with as the pairing position of the tone of mellotron, just chanteur's detonieren whether as can be known.
With reference to figure 2, a kind ofly can comprise acoustic pickup 1, phonetic analysis circuit 2, motor-drive circuit 3, stepper motor 4, base 5, rotating disk 6, driving-belt 7, fixture 8, lead 9, transmission gear 10, rotating shaft 11 and shaft collar 12 with the device that sound rotates.Wherein, acoustic pickup 1 links to each other with the input end of phonetic analysis circuit 2, the output terminal of phonetic analysis circuit 2 links to each other with the input end of motor-drive circuit 3, the output terminal of motor-drive circuit 3 links to each other with stepper motor 4, stepper motor 4 is fixed on the base 5, stepper motor 4 is with driving-belt 7 driven gears 10, gear 10 is fixedly sleeved in rotating shaft 11, rotating shaft 11 is socketed on the fixture 8 in rotating mode, rotating disk 6 is fixed in rotating shaft 11 upper ends, and shaft collar 12 is fixed on the base 5 by hollow fixture 8.
Phonetic analysis circuit 2 and motor-drive circuit 3 are to above-described similar, and its mode of operation is also similar.
When using, on rotating disk 6, place article as indicant, can place any article, if energy is luminous, reflective or other optical effect is better, also can place favourite article of user such as cartoon toy, exquisite souvenir or the like, and can on shaft collar, place article 13, it is by lead 9 energisings or accept other signal.The article that are placed on like this on the rotating disk 6 just relatively rotate with the article 13 that are placed on the shaft collar 12, form more changeableization.
Like this, device of the present invention can rotate with sound, and the article that the placement user likes on rotating disk provide a kind of active feedback as indication to music learning, are beneficial to learner's progress.When it during as a kind of ornament, can place cartoon toy or the elaboration souvenir liked by masses, to rotate rendered atmosphere with music.And can allow hearing degeneration person as music appreciating as the ordinary person.
