Abstract
The utility model discloses an interesting electronic board for babies, which belongs to a sounding playing and teaching equipment. The utility model solves the problems that sound can not be sent out when learning characters from looking pictures and improves the interests of plane teaching. The utility model is characterized in that a plurality of switch circuits are connected with two sounding chips; the chips are connected with a buzzer; switching elements are made of reed switches; the printing positions of each pattern on the pictures and characters thereof are respectively corresponding to the installing positions on circuit boards of a pair of the reed switches of each switching circuit. When used, the pictures are covered on the circuit boards, a teacher and children respectively hold a ferule of which the top end is provided with a magnetic iron, the teacher points at a pattern, and the pattern can send different sounds out according to that the characters pointed by children are right or not.
Description
A kind of child's entertaining electron plate belongs to acoustic toy.
At present general family, kindergarten, school's religion children to learn to read be normal to adopt teaching aid such as the card of learning to read with the aid of pictures, its interesting poor, can not sounding.
In view of the problems referred to above that exist in the prior art, the purpose of this utility model provides a kind of child's entertaining electron plate.Its interest mainly is the literal that is printed on a plurality of patterns and these patterns on picture card, when teacher or the head of a family refer to a certain pattern with teacher's pointer, the child points out the literal of this pattern with another root teacher's pointer, point out according to the child pattern literal to mistake, can send different interesting sound.
The utility model is design like this: it is made up of casing (1), circuit board (2), normal open switch (3), diode, pronunciation stamen sheet, hummer, battery, picture (4), magnetic teacher's pointer (5); Circuit board (2), battery, hummer are housed in the casing (1), and a magnet (6) is adorned on teacher's pointer (5) top.The surface area of circuit board (2) equates with the surface of picture (4), normal open switch (3) is housed above the circuit board (2), picture (4) covers on the normal open switch (3), the back side of circuit board (2) is equipped with other element, element on the circuit board (2) is to connect like this, two normal open switch coupled in series, the positive pole that its connection place connects a diode constitutes an on-off circuit.The negative pole of two utmost points of several on-off circuits that connect is like this connected with the trigger electrode of a LH9300 stamen sheet, the both positive and negative polarity of this stamen sheet connects battery, the positive pole of LH9300 stamen sheet connects with 940CA stamen sheet is anodal, the negative pole of these two stamen sheets is connected in respectively on two non-series connection ends of a pair of normal open switch of each on-off circuit, two hummers is connected on respectively on the output terminal of two stamen sheets again; Several on-off circuits are housed on the circuit board just can on a pictures, print several patterns and literal thereof, two installation sites of normal open switch on circuit board of the respectively corresponding on-off circuit in the printing position of the literal of a pattern and this pattern thereof, normal open switch is selected tongue tube for use.
The utility model has the advantages that the shortcoming that teaching aids such as having overcome the existing card of learning to read with the aid of pictures can not sounding, in the process that the child learns to read with the aid of pictures, can send interesting sound, strengthened the interest of teaching.
Fig. 1 is a section plan of the present utility model.
Fig. 2 is an electrical schematic diagram of the present utility model.
The utility model is achieved in that circuit board (2) surface area equates with the area of picture (4).Circuit board (2) is housed in the casing (1), is tongue tube (3) above the circuit board (2), and picture (4) covers on the tongue tube (3), and other element is installed at the back side of circuit board (2).Element on the circuit board (2) is to connect like this: circuit board is equipped with a plurality of on-off circuits on (2).Each on-off circuit is by a pair of tongue tube (3) coupled in series, and the positive pole that its connection connection place connects a diode constitutes, and the negative pole of the diode of each on-off circuit connects with the trigger electrode of a LH9300 stamen sheet, parallel connection battery between the both positive and negative polarity of this stamen sheet.The positive pole of LH9300 stamen sheet connects with the positive pole of 940CA stamen sheet, and the negative pole of these two stamen sheets connects respectively on two non-series connection ends of a pair of tongue tube of each on-off circuit, and respectively connects a hummer.Circuit board is equipped with several on-off circuits on (2), and picture should be printed several patterns and literal thereof on (4).The installation site of a pair of tongue tube (3) on circuit board of the respectively corresponding on-off circuit in the printing position of pattern and literal thereof.Child's entertaining electron plate is joined two teacher's pointers (5) that magnet (6) is equipped with on several pictures (4) and top.
Claims (2)
1, a kind of child's entertaining electron plate, the surface area that it is characterized in that circuit board (2) equates with the area of picture (4), circuit board (2) is housed in the casing (1), normal open switch (3) is housed above the circuit board (2), picture (4) covers on the normal open switch (3), other element is installed at the back side of circuit board (2), element on the circuit board (2) is to connect like this: circuit board is equipped with a plurality of on-off circuits on (2), each on-off circuit is by a pair of normal open switch coupled in series, the positive pole that its connection place connects a diode constitutes, the negative pole of the diode of each on-off circuit connects with the trigger electrode of a LH9300 stamen sheet, parallel connection battery between the both positive and negative polarity of this stamen sheet, the positive pole of LH9300 stamen sheet connects with the positive pole of 940CA stamen sheet, the negative pole of these two stamen sheets connects respectively on two non-series connection ends of a pair of normal open switch of each on-off circuit, and respectively connect a hummer on its output terminal, circuit board is equipped with several open circuits on (2), picture is just printed several patterns and literal thereof on (4), the installation site of a pair of normal open switch on circuit board (2) of the respectively corresponding on-off circuit in the printing position of pattern and literal thereof.
2, child's entertaining electron plate according to claim 1 is characterized in that described normal open switch (3) is a tongue tube.
