[embodiment]
Fig. 1 to Fig. 4 is respectively vertical view, front view, rearview and the end view of an embodiment of the utility model DPF.Shown in Fig. 1 to 4, this DPF comprises front shell 10, back side shell 12 and supporting leg 13, and supporting leg 13 is hinged to back side shell 12 to support DPF.Front shell 10 is provided with form hole 11, and form hole 11 is used for installing display screen.As a kind of improvement, a transparent panel can also be installed, on form hole 11 to cover form hole 11, with the display screen of protection the inside.
Fig. 5 is the block diagram of an embodiment of the utility model DPF.As shown in Figure 5, this DPF comprises installation main control unit 1, memory cell 2, power supply 4, video unit 5 and audio frequency power supply 6 in the enclosure.Wherein, main control unit 1 is connected with memory cell 2, power supply 4, video unit 5, clock unit 7.
As a kind of improvement project, DPF comprises the time showing module that is connected between main control unit 1 and the display screen, the time showing module receives the time signal that the RTC chip produces, convert the display format that the user sets to, analog digital display format for example shown in Figure 6, graduated time ring perhaps shown in Figure 7 and the display format of pointer.When adopting the display format of graduated time ring shown in Figure 7 and pointer, time showing module generation time dial and calculate the sensing of pointer in graduated time ring according to time signal, pointer is cooperated with graduated time ring to be used for instruction time, for example, represent this time of 10:10 by the sensing of hour hands and minute hand.Display screen receives the data of this time showing module, shows graduated time ring, pointer etc.Adopt graduated time ring and pointer to come the demonstration time, can increase the temperament and interest and the aesthetic feeling of DPF; On the other hand, adopt display screen to show graduated time ring and pointer,, reduced manufacturing cost, also help simplifying the physical size of DPF no longer needing traditional mechanical dial plate and pointer.Correspondingly, function button or menu button can be set on the shell of DPF, this function button and menu button are connected with main control unit 1 and are used to be provided with, the display format of switching time.
As another kind of improvement project, the time showing module can also produce the calendar signal, and video circuit receives this calendar signal and shows by display screen, as shown in Figure 8.
DPF shown in Figure 5 has comprised clock unit, makes DPF have audio-frequency function, has overcome the single defective of traditional digital photo frame function.And Fig. 9 is a kind of block diagram of improved DPF.Compare with DPF shown in Figure 5, DPF shown in Figure 9 also comprises audio unit 6, audio unit 6 comprises voicefrequency circuit and loud speaker, voicefrequency circuit connects main control unit 1 and loud speaker, voicefrequency circuit is used for transmission and processing audio data, the voice data of loud speaker reception and audio plays circuit transmission.For example, shell 12 (with reference to figure 1-Fig. 4) is gone up the through hole of raising one's voice is set overleaf, and loud speaker is installed under the through hole of raising one's voice.In DPF shown in Figure 9, the RTC chip can send the alarm clock signal to main control unit 1, and this alarm clock signal is used in reference to and what is shown in activates alarm clock constantly.Main control unit 1 has produced the instruction of making a noise according to the alarm clock signal in the moment of appointment, and the voicefrequency circuit of audio unit 6 receives and handle, carries out this instruction of making a noise, and rises by described loud speaker and makes a noise, thereby make DPF have the function of alarm clock.
As a kind of improvement to DPF shown in Figure 9, can also increase volume control switch, can comprise volume control button and volume control circuit, the volume control button is installed on the shell of DPF, and volume control circuit is serially connected between described voicefrequency circuit and the described loud speaker.Volume control button and volume control circuit cooperate, be used for control loudspeaker volume, enable and close.Similarly, can also increase the brilliance control switch, the brilliance control switch series is connected between described video circuit and the described display screen, be used to control described display screen the brightness size, enable and close.
Improve as another kind, the RTC chip of clock unit 7 also plays noisy signal to main control unit 1 forward delay interval, once rising to make a noise after this time-delay noisy signal is used to indicate and working the interval time constantly that makes a noise with the last time constantly.By the noisy signal of having delayed time, rising continuously of can realizing being interrupted made a noise, thus " Anti-Snooze " function that makes the alarm clock of DPF have.For example, an Anti-Snooze alarm clock can be set, rising first makes a noise is point in mornings 7 constantly, and the time of making a noise of having delayed time is 10 minutes.Like this, during 7 of mornings, DPF can rise noisy first, and then, if the user does not stop the Anti-Snooze alarm clock of DPF, so, DPF will rise every 10 minutes and make a noise once, promptly rises noisy constantly at 7:10,7:20,7:30 etc. respectively.Correspondingly, the alarm clock control button can also be set on shell, described alarm clock control button is connected with described main control unit 1 and is used to control described the start and stop of making a noise, having delayed time and having made a noise.
As another improvement, the RTC chip can also send timing signal, and main control chip 1 can send corresponding instruction according to this timing signal.For example, with the brightness of display screen be divided into bright, normal, dull, close this four patterns, then, main control chip 1 automatically is suitable for these four kinds of patterns according to timing signal, for example 0 of morning, display screen was a " shut " mode" to 6:00 AM; 6:00 AM is to 12 noon, and display screen is a normal mode; Then, 12 noon is to 6 pm, and display screen is a bright mode; 6 pm to midnight 0 point, display screen is dull pattern.By the pattern of automatic adjusting display screen, both helped saving electric energy, environmental protection has brought new meaning to DPF again, satisfies the demands of consumers.
Figure 10 is the block diagram that carries out improved DPF at DPF shown in Figure 9.Compare with DPF shown in Figure 9, DPF shown in Figure 10 also comprises memory interface 3, memory interface 3 is connected with main control unit 1, be used to connect outside memory, outside memory can be USB flash disk, CF card, SM card, mmc card, SD card, MS card (memory stick), XD card, TF card, MicroSD card or MiniSD card or the like.
By memory interface 3, can perhaps write data from external memory read data to external memory, realize duplicating, back up, shifting or the like of data, help enlarging the use occasion of DPF.As a kind of improvement, can also pass through the renewal that memory interface 3, external memory or storage card are realized software, firmware.Particularly, the software or the firmware of new edition are left in the external memory or storage card, this memory or storage card are received memory interface 3, use external memory or the new edition software in the storage card or firmware to cover original software and firmware (the interior old firmware of flash memory that for example has DPF) in the DPF by the instruction of main control unit 1, realize the renewal of software, firmware.
For further setting forth the circuit connecting relation of each functional module of the utility model DPF, this specification has been enclosed relevant circuit diagram, wherein, Figure 11 is the circuit structure diagram of DPF shown in Figure 10, as shown in figure 11, chip PQFP216 is as the main control unit of DPF, and chip PQFP216 is connected with memory, power supply, built-in RTC, memory interface, video unit, audio unit.
Above-described the utility model execution mode does not constitute the qualification to the utility model protection range.Any modification of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the claim protection range of the present utility model.
