Abstract

The utility model relates to a device which can record and store the needed sound when making a memory book for playing when necessary. The utility model is characterized in that a curtain part of a carrier holding memory piece is provided with a recording-playback device which consists of a digital module recording circuit, a loudhailer, and a recording-playback switch. The periphery of a digital module recording integrated circuit ISD1420G is provided with a recording circuit, a sound reproduction circuit, and an eliminating circuit. When recording, pressing on the recording key and closing the recording switch K1 for triggering signal can ensure that the microphone produces audio frequency analog signals, and then the sound is stored. When reproducing the sound, pressing on the sound reproduction key and closing the switch K 2 can cause a chip triggering decoder to output digital audio frequency signals to the loudhailer. When eliminating recorded content, pressing on an eliminating key 9 is enough. Compared with the prior art, the utility model can save the memorial sound for a long period with unchanged sound, can record repeatedly, in particular, can permanently save the significant memory sound for leaving beautiful memory for people.

Description

The autograph book that has recording device

Technical field

The utility model is a kind of autograph book that has recording device, specifically is a kind of can when making autograph book required sound recording also the storage, the device of broadcast when need being convenient to.

Background technology

In the prior art, most of autograph book, as left autograph book of photograph, birthday card, celebrating red-letter day, mostly be to play the effect that saves image, original sound at that time can not be recorded, as souvenir, particularly child's connatae first sob or each blessing of giving relatives just all can stay a lot sorry to people.

Summary of the invention

The utility model has solved the technical problem that existing autograph book can not recorded voice, and recording and playing device is installed on autograph book, makes the autograph book can the long preservation picture, can keep sound simultaneously again.

The utility model is realized by following scheme, a kind of autograph book that has recording device, contain circuit that can recording/playing function and the carrier of commemorating sheet is housed, it is characterized in that the recording/displaying device that is made of Digital module recording circuit, loudspeaker and recording playback sound switch being housed in a part of being equipped with on the carrier of commemorating sheet.Digital module recording circuit described in the utility model and peripheral circuit are this area those of ordinary skill as long as adopting the Digital module recording circuit to need not creative work just can design, and can have multiple different circuit structure to be out of shape under the situation that realizes identical function.The utility model has provided a kind of particular circuit configurations that can realize above-mentioned functions in the specific embodiment,

The autograph book that has recording device described in the utility model is characterized in that the periphery of Digital module recording integrated circuit ISD1420G is provided with recording circuit, playback circuit and removing circuit, the K switch of recording circuit ₁Through resistance R ₅Link to each other with 27 pin of integrated package, the other end links to each other with 25 pin, and microphone is connected between integrated package 16 pin and 17 pin, and another routing integrated block 28 pin are connected the K switch of playback circuit through light emitting diode D with integrated package 16 pin ₂Through resistance R ₆, R ₇Connect with integrated package 5 pin, loudspeaker (6) is connected between integrated package 16 pin 15 pin, removes the K switch of circuit ₃By 28 pin, 12 pin of integrated package through R ₁Constitute the loop.This device is installed in a part of autograph book, stays the purpose of doing souvenir simultaneously to reach photograph and sound, and recording playback simultaneously.

The utility model compared with prior art have can long preservation sound during souvenir, and stationary tone can be recorded repeatedly, especially has can also forever preserving of important souvenir meaning, stays fine memory to people.

Description of drawings

Fig. 1 is the outside drawing that has the autograph book of recording device

Fig. 2 is the circuit diagram that has the autograph book of recording device

Among the figure: 1, recording switch 2, playback switch 3, remove contactor 4, light emitting diode 5, microphone 6, loudspeaker 7, hold-down screw 8, record button 9, remove strong 10, photograph album 11, recording indication 12, go up a page or leaf playback button 13, the nextpage playback is strong

The specific embodiment

With reference to the accompanying drawings embodiment is further described, present embodiment is to be example with the photograph album, the recording device that is made of Digital module recording integrated circuit ISD1420G and peripheral recording circuit, playback circuit and removing circuit is housed in the bottom of photograph album 10, fixing with hold-down screw 7; The periphery of Digital module recording integrated circuit ISD1420G is provided with recording circuit, playback circuit and removing circuit, the K switch of recording circuit ₁Through resistance R ₅Link to each other with 27 pin of integrated package, the other end links to each other with 25 pin, and microphone is connected between integrated package 16 pin and 17 pin, and another routing integrated block 28 pin are connected the K switch of playback circuit through light emitting diode D with integrated package 16 pin ₂Through resistance R ₆, R ₇Connect with integrated package 5 pin, loudspeaker (6) is connected between integrated package 16 pin 15 pin, removes the K switch of circuit ₃By 28 pin, 12 pin of integrated package through R ₁Constitute the loop.During recording, press recording and be good for 8, recording switch 1K closes ₁Through resistance R ₅With 27 pin of integrated package through 17 pin triggering signals, make 17,16 two ends produce audio analog signals, and be stored in and form digital audio and video signals in the integrated package through microphone 5.During recording, the recording of light emitting diode 4 indication 11 shows; During playback, press playback strong 12 or descend playback to be good for 13, at this moment, switch 2K ₂Close, electric current is through resistance R ₆, R ₇To integrated package 5 pin trigger decoders by 15 pin to loudspeaker 6 outputting digital audio signals.When removing recording substance as needs, press to remove and be good for 9, clear switch 3K closes ₃, integrated package by 28 pin and 12 pin through R ₁Constitute the loop, remove recording at first.
