Abstract

The utility model discloses an individualized electronic greeting card, is which is composed of a circuit board (1), an SP loudspeaker (2), a battery (3), a circuit shell (4), a drawing switch (5), and an invitation card casing (6). The utility model belongs to the speech electronic field, and solves the technical problems of pasting a thin shell with the circuit board on a greeting card, playing back speech, opening and closing the switch driven by the opening and closing of the greeting card. The utility model adopts the methods of voice, words and images to bless and express the blessing emotion of a wisher to the other party.

Description

E-greeting card

The utility model is a kind of individual electronic greeting card, and it can send felicitator's sound.

Present widely used greeting card generally is single page paper folding, and the felicitator explains the fine wish of felicitator with blessing the other side's congratulatory words and vivid pattern.Though the electronic music greeting card has also been arranged, relatively more dull, stereotyped, and be disposable music to be solidificated in the integrated circuit, can not change.In order to express felicitator individual emotion better, embody personalized.According to general electronics basic principle, the speech IC principle is with reference to the books such as " Voice Recordand Playback ICs " of American I SD company.Conceived the individual electronic greeting card.

The purpose of this utility model provides the e-greeting card that a kind of individual could record and send felicitator's sound.

The purpose of this utility model be achieved in that it by greeting card crust, carton shell, can write down sound circuit, loudspeaker, battery and Drawing switch and form; Wherein paste the shell that the circuit printed circuit board (PCB) is housed on the greeting card shell, but internal circuit has adopted the speech IC of a recording voice, output SP+, the SP-one tunnel of IC1 are connected to loudspeaker SP, and the input of driver BT1 is delivered on another road, and the output of BT1 is connected to luminescent device D1; The end ground connection of playback switch SW1, the other end are connected to the PL end of IC1; 3,4 of socket J1 is connected to MIC and the MICREF end of IC1, and 5 of J1 is connected to the RECLED end of IC1, and 6 of J1 is connected to the REC end of IC1.1 end of J1 is the external power input, and 2 ends of J1 are ground wires.

Owing to adopt such scheme, realized purpose with personal voice blessing the other side.Because of using large scale integrated circuit, peripheral capacitance resistance ware seldom, structure is small and exquisite, debugging is simple.

Below in conjunction with drawings and Examples the utility model is further specified:

Figure 1A, 1B are front elevation and the vertical section structure figure of the embodiment of individual electronic greeting card.

Fig. 2 is the cross section structure figure of Drawing switch.

Fig. 3 is an individual electronic greeting card internal circuit schematic diagram.

In Figure 1A, 1. circuit board 2.SP loudspeaker 3. batteries 4. circuit cases 5. Drawing switches 6. e-greeting card shells.

Shown in Figure 2 is the Drawing switch of embodiment, is an ambroin sheet, and its end inserts the central authorities of reed contact, and the other end sticks on the another side of greeting card folding, opens folding, the pulling plastic sheet, and reed contact joins, and realizes the connection of switch.

In circuit theory diagrams embodiment illustrated in fig. 3, IC1 is a core component, and it has adopted many level analog quantity memory technology, international, domesticly commercially produces, the APR9600 that ISD1100,1200,1400 series of products and the Taiwan of ISD company are arranged, products such as IVS1560.This circuit adopts mask technique that IC wafer directly is encapsulated on the printed circuit board (PCB).During recording, 6 ends of socket J1 are sent into the REC end that a low level signal is given IC1, and the IC1 opening entry is sent into voice signal by 3,4 ends of J1.The RECLED end of IC1 is sent 5 ends that a low level signal is given J1.R1, C1 form the passage that the inner preamplifier of IC1 outputs to the record buffer input of IC1 inside, and their size influences the frequency response of voice signal.The effect of R5, C5 is a dynamic range of determining the inner AGC of IC1.After SW1 connected, the PL of IC1 end was low level, and the audio signal of IC1 record directly outputs to SP (loudspeaker) playback.This signal is delivered to driver BT1 via the C3 even summation simultaneously, and it is luminous to drive luminescent device D1.

Claims

1, a kind of individual electronic greeting card is characterized in that by greeting card crust, carton shell, can write down sound circuit, loudspeaker, battery and switch and form; Wherein paste the carton that the circuit printed circuit board (PCB) is housed on the greeting card crust, but internal circuit has adopted the speech IC of a recording voice, output SP+, the SP-one tunnel of IC1 are connected to loudspeaker SP, and the input of driver BT1 is delivered on another road, and the output of BT1 is connected to luminescent device D1; The end ground connection of playback switch SW1, the other end are connected to the PL end of IC1; 3,4 of socket J1 is connected to MIC and the MICREF end of IC1, and 5 of J1 is connected to the RECLED end of IC1, and 6 of J1 is connected to the REC end of IC1.The 1 termination external power of J1, the 2 termination ground wires of J2.

2,, it is characterized in that plastic sheet of folder between Closing Switch SW1 two contacts, pull plastic sheet, the connecting and disconnecting of determine switch according to right 1 described individual electronic greeting card.
