Multifunctional children study detector is by the pairs of switches device, and letter disk alignment device harmony optoelectronic circuit forms.

The pairs of switches device is established steel ball and spring seat (15) in mid-game (1), spring (12) is housed in the spring base, steel ball (13), symmetrical aperture is offered in steel ball and spring seat both sides, aperture is passed respectively at lower contact (11) two ends, one end be positioned at contact (10) below, cut-off with spring, the other end and acoustic-optic circuit communication, the middle part is connected with spring, steel ball cover (14) is with spring, steel ball is enclosed in the steel ball and spring seat, available spring leaf replaces steel ball (13), spring (12) and lower contact (11), acousto-optic electrical appliance kit (16) is equipped with in the mid-game inboard, upward on dish (2) and lower partitioning disk (3), bulb is housed, is connected with power supply by brush, offer fan-shaped elongated slot (23) on the upper lower partitioning disk, offer fan-shaped sulculus (24) along involute path on the contraposition dish up and down, upper lower partitioning disk and contraposition dish connect separately to be done to rotate synchronously.

The letter disk alignment device is connected to one with mid-game (1) by interior up and down letter disk (8) (9), outer up and down letter disk (6) (7) is connected to one with axis (20), on inside and outside up and down letter disk, mark some sector cells with lines, arrange word content by rule in the sub-district, as the Chinese and the Chinese phonetic alphabet, English and phonetic symbol, primary arithmetic facts computing and result etc., with the Chinese phonetic alphabet is example, interior up and down letter disk (8) (9) is gone up typesetting and printing phonetic initial consonant in the sector cell, outer up and down letter disk (6) (7) is near interior letter disk edge cell typesetting and printing phonetic simple or compound vowel of a Chinese syllable, Chinese character is typeseted and printed in the sector cell in the letter disk outside, can typeset and print on the initial consonant of interior letter disk up and down on the side circumference of mid-game (1), the simple or compound vowel of a Chinese syllable of outer up and down letter disk (6) (7) also can be typeseted and printed on the circumference of letter disk outside, a study detecting device can be made the content of one or more subject study, only need replace with down inside and outside letter disk during use.

The sounding electronic circuit is by the simulation ic chip ₁, triode, loudspeaker and electronic component are formed.IC ₁, IC ₂Constitute oscillation frequency control circuit, IC with R ₄Pass through K switch ₁Constitute oscillatory trigger circuit, IC ₅Be output stage, output signal promotes the loudspeaker sounding after triode BG amplifies, and luminescent line is by ic chip ₄, IC ₁₀Connect light emitting diode respectively, touch switch K ₂, it is luminous to promote the diode circulation, with the sounding K switch ₁With illuminated switch K ₂Merge, an end of linked switch is communicated with last contact in the mid-game again, the other end is communicated with following contact in the mid-game and reaches acoustic luminous effect of while.
