A kind of speech chronopher electronic clock with acoustic control induction and seven color conversions
Technical field
The utility model relates to a kind of electronic clock, relates in particular to a kind of speech chronopher electronic clock with acoustic control induction and seven color conversions.
Background technology
Existing electronic clock is solid form often, does not have dynamic setting, generally has only single time clock feature, can't attract popular eyeball.In addition, present LED seven color backlight type clocks are good and cheap, fashionable, accurate when walking with its product, have been widely used in family and public place, but this type clock often volume is bigger, be not easy to carry, do not have strong functions again.
Summary of the invention
In order to overcome the deficiency of prior art, the purpose of the utility model is to provide the speech chronopher electronic clock of a kind of powerful, little portable band acoustic control induction of volume and seven color conversions.
A kind of speech chronopher electronic clock of the utility model with acoustic control induction and seven color conversions; It comprises shell; Shell one end face is provided with display screen, is provided with PCB circuit board, battery, LED seven-color LED, sound out-put circuit harmony sound inductor in the said shell, and the input end of PCB circuit board connects battery harmony sound inductor respectively; Its output terminal connects LED seven-color LED and sound out-put circuit respectively; The PCB circuit board is provided with perpetual calendar chip circuit, acoustic control sensor circuit, LED seven-color LED control circuit and speech chronopher circuit, and sound out-put circuit one end is connected with the speech chronopher circuit, and the other end is connected with loudspeaker.
Said shell is connect by translucent gluing shell and following glue valve jacket and forms.
Said display screen is glass display screen or LCDs.
Said battery is located at down in the battery case of glue shell bottom surface, and the battery case of following glue shell bottom surface is provided with battery cover.
Be provided with delay circuit in the said LED seven-color LED control circuit.
The band acoustic control induction of the utility model and the speech chronopher electronic clock of seven color conversions; Powerful, good looking appearance, volume are urinated in carrying; Through lighting of acoustic control induction control LED seven-color LED; Do not need direct contact, and the light of LED seven-color LED after lighting can directly illuminate display screen, it is extremely convenient that use night; The product of the utility model also has the function of speech chronopher.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is the exploded view of the speech chronopher electronic clock of the utility model band acoustic control induction and seven color conversions;
Fig. 2 is the synoptic diagram of the utility model PCB circuit board.
Embodiment
Like Fig. 1 or shown in Figure 2; A kind of speech chronopher electronic clock of the utility model with acoustic control induction and seven color conversions; It comprises shell 1; Shell 1 one end faces are provided with display screen 2, are provided with PCB circuit board 3, battery 4, LED seven-color LED 5, sound out-put circuit 6 harmony sound inductors 7 in the said shell 1, and the input end of PCB circuit board 3 connects battery 4 harmony sound inductors 7 respectively; Its output terminal connects LED seven-color LED 5 and sound out-put circuit 6 respectively; PCB circuit board 3 is provided with perpetual calendar chip circuit 31, acoustic control sensor circuit 32, LED seven-color LED control circuit 33 and speech chronopher circuit 34, and sound out-put circuit 6 one ends are connected 34 with the speech chronopher circuit, and the other end is connected with loudspeaker 8.
Said shell 1 is formed with following glue shell 12 sockets by translucent gluing shell 11.
Said display screen 2 is glass display screen or LCDs.
Said battery 4 is located at down in the battery case of glue shell 12 bottom surfaces, and the battery case of following glue shell 12 bottom surfaces is provided with battery cover 9.
Be provided with delay circuit 35 in the said LED seven-color LED control circuit 33.
During the electronic clock operate as normal of the utility model, show the perpetual calendar time on the display screen 2.
The band acoustic control induction of the utility model and the speech chronopher electronic clock of seven color conversions; When the sound of periphery during more than or equal to 75DB, the acoustic control sensor circuit 32 in it just can receive the sound of periphery, and sends to the acoustic control sensor circuit 32 on the PCB circuit board 3; Acoustic control sensor circuit 32 sends signal for LED seven-color LED control circuit 33; And then control LED seven-color LED 5 and light and turn colors, light appears through translucent shell 1, makes things convenient for use night.When slightly touching shell 1 with hand or other object; Or alarm clock is when sounding, and acoustic control sensor circuit 32 also can receive signal, and then control LED seven-color LED 5 is lighted; When the time of lighting reached the setting-up time of delay circuit 35 in the LED seven-color LED control circuit 33, LED seven-color LED 5 can extinguish automatically.
When the time that shows on the electronic clock reached the time of setting, the speech chronopher circuit 34 on the PCB circuit board 3 was connected, and sent signal for sound out-put circuit 6, and the loudspeaker 8 that connect through sound out-put circuit 6 other ends carry out speech chronopher.
