Abstract

The utility model relates to a multifunction electronic reminder, which is composed of an outer casing, an inner circuitboard and a power section. The utility model is characterized in that the inner circuitboard comprises a timing chip IC1 circuit and is connected to a sound recording chip IC2 circuit through a universal mercury switch and a recording and reproducing key; then the signal output is amplified by a power amplification chip IC3. The utility model can preset the reminder time as needed and automatically play the recorded speech. The utility model is handy, compact and convenient in carrying, and can also be a help device required by old people.

Description

The multifunction electronic reminiscences

The design belongs to life and uses small-sized electronic product, specially refers to and utilizes the sound chip circuit alarm playback, a kind of multi-functional prompting utensil of reminds people action.

When people have much to do, usually can forget or neglect some these things of doing, especially; the people is to old; usually forget things easily, China aged ratio is very big, and some the elderly often forgets and takes medicine on time; they more wish to obtain at any time to remind; wait some simple promptings such as " this has been taken medicine now, and so-and-so eats several by medicine, and so-and-so eats several by medicine "; can the words of prior typing be sent to controlling oneself regularly four hours or other fixing hours.Except taking medicine, also can remind and do other important thing, as participate in momentous conference, dial important phone on time, and, for the old people who goes out separately, can also remind others to help as " two's complementer ", as " I have heart disease; please the medicine of coat pocket is obeyed down to me ..., my family's phone is * * * *, please help ... ".As one of health care articles for use of the elderly, design this series products, also be our society to the elderly's care and a responsibility that should use up, also do not have the product of above-mentioned functions at present on the market.

Purpose of the present invention is to remind for the thing of people being forgotten easily and must do, and can obtain help at once in the time of especially need seeking help to the elderly.Thereby a kind of electronic apparatus that utilizes sound chip circuit that people are reminded of design.

The objective of the invention is to rely on following technical proposals to realize, a kind of multifunction electronic reminiscences, constitute by shell body, internal circuit board and power unit, principal feature is, internal circuit board comprises timing chip IC 1 circuit, be connected on the recording chip IC2 circuit through universal mercury cut-off and record, playback button, will export voice signal by power amplification chip IC 3 circuit again and export by loudspeaker.

This device is light, small and exquisite, be easy to carry, cumulative volume is big or small the same with a cigarette package, and people are according to the needs of controlling oneself, in advance with in the voice typing chip of reminding, give on demand and having put reminder time, by recording switch, after the sound typing that is no more than 20 seconds, then just can automatically the speech play of typing be come out, reminds people is done something, and real is people's good assistant.

Below in conjunction with accompanying drawing, further specify embodiment:

Description of drawings:

Fig. 1 is the general arrangement figure of multifunction electronic reminiscences;

Fig. 2 is each chip composition diagram of internal circuit board;

Fig. 3 is each chip circuit wiring diagram of internal circuit board.

Wherein, housing 1 is made by plastics or other organic materials, and shell face and bottom closely cooperate and be that complete body, housing face are provided with MIC, LED aperture, S2, S3 button and switching knob, and the shell bottom has the loudspeaker small perforations.Internal circuit board 2 comprises timing chip IC 1 circuit 2.1, chip DC40603 pin is connected with universal mercury cut-off and is connected to recording chip IC2 circuit 2.2 by record, playback button, IC2 is ISD1420, its 17,18 pin are connected to MIC, but cooperate typing to be no more than 20 seconds voice with record button S3, S2 is a playback button, presses S2 and the voice of typing can be emitted.

IC1 chip CD4060 can produce timing pip, after by power connection, counter is started working, and when counting reaches 14, makes 3 pin present noble potential, N2 starts working, making the N3 base stage is positive conducting, and 24 pin of ISD1420 become electronegative potential to begin playback, regulator potentiometer R19, can change oscillation frequency, its time-delay was changed between 30 minutes to 4 hours.

As when connecting S4, this utensil is in plumbness, and mercury cut-off is obstructed, and the N2 base stage is 0, does not work, and N3 does not work yet, and 24 pin of ISD1420 connect noble potential, not sounding.As make this apparatus shell when any direction inclination is spent above 45, and mercury cut-off is connected, and the N2 base stage is positive conducting, and the N3 base stage is positive conducting also, makes 24 pin of ISD1420 become electronegative potential, the beginning playback.The playback signal is exported by loudspeaker SP after amplifying by power amplification chip IC 3 circuit 2.3.In the connecting circuit of universal mercury cut-off K, owing to be connected to time-delay conducting loop; R18 and E4 can make N2 time-delay conducting about 3 seconds, just can eliminate because of carrying this utensil when walking, the noise that causes owing to the mercury cut-off switch-on and-off, in the connecting circuit of the N3 that is comprised in the circuit, be connected to the loop playback circuit, in case playback begins, playback capable of circulation just stops playback until off switch.Power unit 3 is the battery cases that can adorn No. 5 baby batteries of 4 joints, and the voltage during work is 6V.

Claims

1, a kind of multifunction electronic reminiscences, constitute by shell body [1], internal circuit board [2] and power supply [3] part, it is characterized in that, internal circuit board comprises timing chip IC 1 circuit [2.1], be connected on the recording chip IC2 circuit [2.2] through universal mercury cut-off K and record, playback button S1, S2, will export voice signal by power amplification chip IC 3 circuit [2.3] again and export by loudspeaker SP.

2, reminiscences according to claim 1 is characterized in that, the connecting circuit of the universal mercury cut-off K that is comprised in the circuit is connected to time-delay conducting loop, to eliminate noise.

3, reminiscences according to claim 1 is characterized in that, in the connecting circuit of the N3 that is comprised in the circuit, is connected to the loop playback circuit, in case playback begins, playback capable of circulation just stops playback until off switch.
