Abstract

The utility model relates to an electronic speech sound device for alarming which comprises a timing circuit, a reminding circuit and a speech sound storing circuit, wherein, the reminding circuit is triggered by pulse output by the timing circuit, a loud speaker B is pushed by the output of the reminding circuit and the speech sound storing circuit, and a microphone MIC is used as the input of the speech sound storing circuit. As the circuits basically adopt integrated chips, the utility model has the advantages of simple structure, low cost and convenient operation.

Description

The electronic speech reminiscences

The utility model relates to Digital Data Processing Equipment, particularly the electronic speech reminiscences that reminds people is regularly kept record and the energy voice are explained.

In the prior art, Chinese patent (publication number: CN2117631U) disclose a kind of by LCD, generator, keyboard, loudspeaker, amplifier, central processing unit, amplifier, speech processor, " the electonic speech memo pad " that IO interface and random memory are formed, be characterized in easy to use, but the complexity that structure shows.

The purpose of this utility model is: propose a kind of simple in structure, regularly, write down electronic speech reminiscences easily.

Realize that scheme of the present utility model is as follows: the timing circuit output pulse signal control controllable silicon V that it is made up of the digital display type time controller _SConducting, controllable silicon V _SThe alert circuit that triggering is made up of a music-integrating block, this alert circuit exports the loudspeaker sounding to, also can make voice signal deposit a permanent memory type speech IC in by microphone MIC simultaneously, and the output of this speech IC promotes the loudspeaker sounding.

Characteristics of the present utility model are: because described circuit mostly adopts integrated circuit component, it is simple in structure, with low cost, use is also very convenient.

Below in conjunction with accompanying drawing utility model is described further.

Fig. 1 is an electrical schematic diagram of the present utility model.

As shown in Figure 1, the utility model comprises regularly, three parts deposited in prompting and voice, and timing circuit comprises a 903B digital display type time controller, and it is a kind of digital and electronic clock movement, its output terminals A L serial connection forward diode VD ₁With meet controllable silicon V after the resistance R 1 _SGrid.Alert circuit is a music integrated circuit, its input end 1 pin and controllable silicon V _SPositive pole link to each other,

output terminal

2,3 pin meet loudspeaker B, controllable silicon V _SMinus earth.

Voice are deposited circuit and are comprised a permanent memory type speech IC SR9G26, and 23,27 pin meet power supply V behind series resistor R3, the R2 respectively _CCMake its by clamper in high level, simultaneously 23 pin also meet keyswitch AN2,27 pin meet keyswitch AN1, the other end ground connection of AN1, AN2,14 pin of SR9G26 meet forward diode VD3, V ₁₅Pin meets backward dioded VD ₄The back links to each other with loudspeaker B, meets power supply V behind its 17 pin polyphone capacitor C 4, resistance R 6, the R7 _CC, connect the pin of microphone MIC, another pin ground connection of MIC, power supply V in the junction of R6 and R7 _CCA node by single-pole double-throw switch (SPDT) S links to each other with output terminal 3 pin of music integrated circuit, b node by S, being connected in series capacitor C 1 back again links to each other with 27 pin of SR9G26, other is the standard peripheral auxiliary circuits of SR9G26, they comprise: 1,2,3,4,5,6,9,10,12, the 13 pin ground connection of SR9G26, V _CCSerial connection LED, resistance R 4 backs link to each other with 25 pin of SR9G26, and the b node of S switch links to each other with 28,16 pin of SR9G26, and this 6 node also passes through to be connected in series capacitor C 2 and links to each other with 13 pin 12.Between 20 and 21 pin, be connected with resistance R 5, capacitor C 3, at 19 pin and resistance R 8, capacitor C 5 are arranged, and the other end ground connection of R8, C5.

This device service routine is as follows: with reference to figure 1, put S, record the content of the incident of will handling by MIC by AN1 in b, record finish after, put S in a.After the alerting signal of warning system sends, put S in b, press AN2, the content that loudspeaker just will record is in advance emitted, and reminds people is this What for thing now.

Claims
