Abstract

The utility model relates to a multifunctional sounding electronic toy, which is used for developing intelligence and training languages for children and is composed of four CMOS integrated circuits, two microphones and a loudspeaker, wherein, one integrated circuit is used as a language processor, one integrated circuit is used as a random-access memory, one integrated circuit is used as a power amplifier, and one integrated circuit is used as a musical circuit. Functional conversion is executed through a two-knife three-position switch. A star-shaped capacitance-resistance interlinkage device is used for inputting signals into the power amplifier. Except for one microphone, one loudspeaker and batteries, an integral toy is arranged on a printed circuit board in a plastic shell. A direct-current power supply of 9V is used for supplying electricity.

Description

Multifunction sounding electronic toys

A kind of multi-functional sounding electronic toy that is used for children's intelligence exploitation and speech training, it is particularly suitable for, and the child reads aloud before the order to learning, sing, foreign language pronunciation training and play melody and use.

The electronic toy of energy sounding all belongs to for making child's happiness at present, reaches amusement, and the purpose that improves interest designs, and children are carried out certain language ability training, the sound electronic toy prematurity still with the performance of teaching through lively activities; The electronic toy of some sounding is structurally complicated, and especially record type is adopted in the realization of language, pronunciation training function more, and cost is just higher.

For children's intellectual development and speech training, realize by the electronic toy of sounding, reach and teach through lively activities; The utility model is main built-up circuit with ultra-large type CMOS integrated circuit, finishes the record and the regeneration of language, has reduced cost.

On function, can read aloud, sing, the training of foreign language pronunciation.

At first make language processor with a CMOS ultra-large type integrated circuit for this reason, two integrated circuits are done dynamic random access memory and music circuit in addition, and acceptor's language is finished with two microphones with the task of singing signal, CMOS ultra-large type integrated circuit carries out two-way being electrically connected with the integrated circuit of making the dynamic access device, and two pins of CMOS integrated circuit, one connects transmitter, and one connects conversion switch break; Other two breaks of change-over switch are then connecting the microphone and the music integrated circuit of a band radome; The movable contact of change-over switch then connects the integrated circuit of a capacitance-resistance interlinkage device and power amplifier, signal by " " type capacitance-resistance interlinkage device is transported to power amplifier and gets on, and after all signals are amplified by an integrated power amplifier, promotes speaker operation.

When toy is converted to another kind of function from a kind of function, carry out with function switch; Whole toy uses the powered battery of a 9V DC voltage.

In time control, be divided into three seconds with six seconds two kinds, be applicable to children below three years old in three seconds, then be suitable for bigger children in six seconds.

Except that microphone, loudspeaker and battery, all devices all are contained on the interior printed circuit board of a plastic casing.By embodiment, the contrast Figure of description--electrical schematic diagram illustrates concrete structure situation now.

Super large integrated circuit Ic1 model is μ M5101, makees language processor.

Integrated circuit Ic2 model is 4164, makees random access memory.

Integrated circuit Ic3 is a power amplifier.

Integrated circuit Ic4 is a music circuit, and model is optional;

Variable resistance 0～10K Ω; Capacitor 0.47 μ f

1,2 two microphones have a band guard shield, and speaker is 0.25W; A function switch is selected three forms of two cuttves for use.

Power Vcc is the 9V dc source.
