Abstract

The utility model relates to a key-ring craft electronic watch, comprising a key-ring, an outer shell of the electronic watch, an electronic watch, a music integration amplification circuit, and a small trumpet. The electronic watch of the utility model is characterized in timing, alarming, and appreciating. The key-ring craft electronic watch has the advantages of shapely configuration, small size, convenient carrying, good alarming effect, and low cost, which is an excellent commodity, and a best tourism product as well.

Description

Key-ring craft electronic watch

The utility model belongs to portable type timing articles for use.

Being seen in the market electronic watch mostly is handset type, choker, and we feel inconvenient in use sometimes; When existing electronic watch is done regularly to give the correct time, because of sound is too little, the weak effect that makes a noise.

Invention of the present utility model is exactly for not enough a kind of effect of better giving the correct time that has, the key-ring craft electronic watch easy to use of providing of above electronic watch is provided.

The purpose of this utility model can reach by following measure:

On the following ring of key ring, be buckled with plastics or metal electronic watch shell, LCDs arranged on the watchcase and adjust button, electronic watch integrated package, switching tube, music-integrating block, amplifying circuit and toy trumpet are arranged in the watchcase.

The purpose of this utility model can also reach by following measure:

The power supply of electronic watch is supplied with by Ag-oxide button cell, and the electronic watch integrated package is circumscribed with oscillating capacitance and quartz crystal and internal circuit formation oscillatory circuit and provides time-base signal for electronic watch.The electronic watch integrated package is circumscribed with filter capacitor and constitutes booster circuit with boost capacitor and internal circuit and provide driving voltage for liquid crystal display.The electric routing switch pipe that gives the correct time links to each other with the electronic watch integrated package, switch controlled music integrated amplifier; Music integrated circuit has outer meeting resistance, power amplifier, Ag-oxide button cell and toy trumpet.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the novel stereographic map of this reality.

Fig. 2 is a circuit diagram of the present utility model.

Fig. 1 is a stereographic map of the present utility model, by key ring ［ 1 ］, electronic watch shell ［ 2 ］, toy trumpet ［ 3 ］, electronic watch ［ 4 ］, adjustment the Show Button ［ 5 ］.

Fig. 2 is a circuit diagram of the present utility model, and electronic watch is made of electronic watch ic chip 1 and liquid crystal display.C1, C2 are that filter capacitor and boost capacitor are the external capacitors of IC1.They and IC1 internal circuit constitute booster circuit provides driving voltage for liquid crystal display.C3 is an oscillating capacitance, and XT is a quartz crystal, and C3, XT constitute crystal oscillation circuit provides time-base signal to IC1.The power supply of IC1 is supplied with by the 1.5V Ag-oxide button cell.AN1 is for adjusting time button, and AN2 is the Show Button.If whenever press then electronic watch display screen appearances that circulate in the following order of AN1 on the basis of normal time: the time flashes during band AL printed words noisy, and flash the time position of making a noise, and flash the branch position of sudden strain of a muscle, month position, day position, the time position, divide the position, recovery normal time.Whenever by just can press as required behind the AN1 A2 adjust the moon, day, the time, branch, make a noise the time-division.But must be noted that 24 systems that show show and 12 systems show, 12 systems divide in afternoon in the morning, and R represents the morning, and P represents afternoon, and H represents 24 systems; Adjustment is 12 systems and 24 system circulation appearance during the time.There is { ［ () ］ } symbol to occur if regularly rising makes a noise must press AN1, AN2 simultaneously to display screen.As long as if want to understand month, day, press AN2 when making a noise then for occurring month, day successively and when noisy and second demonstration.

Music timekeeping circuit comprises switching tube BG1,2,3 volts of silver oxide cells of music integrated block IC, IC2 outer meeting resistance R, amplifying triode BG2,3 and toy trumpet.

The utility model and prior art relatively have following advantage:

1, easy to carry.

2, rise make a noise effective.

3, can make handicraft, elegant in appearance.

4, volume is little, and is simple in structure, and cost is low, is convenient to a large amount of productions.

Claims

1, a kind of key-ring craft electronic watch of forming by electronic watch shell, electronic watch, key ring, internal circuit; The shell that it is characterized in that electronic watch is except that LCDs and two knobs, and there is a key ring upper end of shell; Electronic watch has the output of making a noise and links to each other with the music amplifying circuit by the open pipe pipe, and electronic watch and music amplifying circuit power supply are supplied with by Ag-oxide button cell.

2, key-ring craft electronic watch according to claim 1, signal is the trigger pip of music amplifying circuit and links to each other with the music amplifying circuit by switching tube when it is characterized in that electronic watch makes a noise.

3, key-ring craft electronic watch according to claim 1 is characterized in that the music amplifying circuit is made up of switching tube, music-integrating block, amplifier tube and toy trumpet.
