Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic device with a recording function that is capable of recording audio.

Recently, electronic devices have become more multi-functional, for example,
Some electronic watches are equipped with alarm functions, timer functions, and the like. For example, the alarm function is used to notify the time by sounding a single tone of a predetermined frequency or a melody sound of a predetermined song title when the alarm time arrives. However, alarm sounds can only produce melodic sounds, which are determined by the manufacturer, and not only do they not suit the user's tastes, or they become boring quickly.
It is difficult to intuitively understand what the emitted alarm sound means, that is, what the alarm time was set for, and it is difficult for the user to memorize and distinguish the meaning of the alarm time in advance. The inconvenience of having to do so has arisen.

Therefore, it is conceivable to record the alarm requirements in the form of audio in a tape recorder or semiconductor memory, etc., and to reproduce the alarm information. However, when using a tape, etc., there was a drawback that the device itself became large. In addition, when using semiconductor memory, etc.
Since the recording time is short and it is not possible to record for a long time like with tape, the voice to be recorded must be input within the recordable time, resulting in recording errors.

This invention was made in view of the above circumstances,
The purpose of this is to be able to easily record a desired sound from the outside, and also to be able to hear the recorded content as a notification sound for example, an alarm time. To provide an electronic device with a recording function that can prevent recording mistakes and ensure recording by displaying the following.

Hereinafter, the present invention will be explained in detail based on an embodiment shown in the drawings. FIG. 1 is a circuit diagram of an electronic clock that notifies alarm time by sound.

and digitally displayed.

Next, the operation of the electronic timepiece configured as described above will be explained with reference to the timing chart shown in FIG. 4, the display state diagrams shown in FIGS. 1 and 2, and FIGS. 6 1 and 2. First, when a signal of "1" is output from the side output terminal of the binary flip-flop 10, the display control circuit 4
AND circuits 37, 28, 43, and 46 are each gated off. Therefore, the PM information, day of the week information, hourly information, and minutely information obtained by the counting circuit 3 are passed to the display control circuit 4 through the corresponding AND circuit.
The signal is sent out from the terminal and given to the liquid crystal display section 5. As a result, the current time and day of the week information are displayed on the liquid crystal display section 5. That is, for example, as shown in FIG. 5, the first digital display section 49 displays "10 o'clock" in hours, and the second digital display section 50 displays "30" in minutes. The current time "10:30" is clearly displayed, and among the dot displays on the first analog display section 51a, the fourth dot display counting from the left end in the figure is turned on to indicate "Wednesday". ”, and furthermore,
The dot display of the second analog display section 51b is driven to light up, and the first and second digital display sections 4
It is clearly shown that the times displayed at 9 and 50 belong to the afternoon time zone.

Next, when the display switching switch _S1 is operated, a pulse signal is output from the one-shot circuit 8.
The output state of binary flip-flop 10 is inverted. As a result, a signal of "1" is output from the Q side output terminal of the binary flip-flop 10. Therefore, in the display control circuit 4, the gates of the AND circuits 44 and 47 are released, so that the AND circuits 44 and 47 correspond to the hourly information and minute information of the alarm time set in the alarm time setting circuit 6. Sent via . Therefore, the liquid crystal display section 5 displays, for example, the image shown in FIG.
As shown, the alarm time of "12:35" is displayed.

In the alarm mode where this alarm time is displayed, if you operate the recording switch S ₂ ,
The operation signal of this switch _S2 is applied to the one-shot circuit 9, causing the one-shot circuit 9 to output one pulse signal as shown in FIG. Therefore, the AND circuit 1 whose gate is released by the Q side output signal of the binary flip-flop 10
When this one pulse signal is output from 1, the down counter 13 is preset to "8". Further, one pulse signal outputted from the AND circuit 11 is given to the switch control section 12. In this switch control section 12, as shown in FIG.
As shown in FIG. 4, the RS type flip-flop 31 is set, and a signal of "1" is output from the Q side output terminal of the binary flip-flop 35, as shown in FIG. The Q side output signal of the flip-flop 31 is sent out as a control signal _f1 from the switch control section 12, and
AND circuit 32 is gated. Since the AND circuit 32 is given a 2Hz output as shown in FIG. 4, the AND circuit 32 outputs a 2Hz signal as shown in FIG. It is counted. The contents counted by the octal counter 33 are sent to the display control circuit 4. Since the display control circuit 4 is supplied with the control signal f ₁ and the Q-side output signal of the binary flip-flop 10, the gate of the AND circuit 40 is released. Therefore, the contents of the octal counter 33 are sent out from the display control circuit 4 via the AND circuit 40 and the OR circuit 42, and provided to the analog display section 51. Therefore, in the liquid crystal display section 5, the digital display sections 49 and 50 display the alarm time "12 o'clock".
35 minutes" is displayed, and each dot display on the analog display section 51 is lit sequentially from the left end every 0.5 seconds, and all dot displays are lit after 4 seconds as shown in Fig. 6-1. Then, the dot display 51b corresponding to the fixed display "START" lights up, instructing to start recording.

On the other hand, as the control signal f ₁ is output from the switch control section 12, the buzzer sound signal generation circuit 2
9 is activated and gate circuit 30 is de-gated. Therefore, a buzzer sound signal is output from the buzzer sound signal generation circuit 29 and is applied to the speaker 25 via the gate circuit 30, whereby a buzzer sound of a predetermined frequency is generated. This buzzer sound is generated while the control signal f ₁ is being output from the switch control section 12.

In the switch control unit 12, when eight pulse signals are output from the AND circuit 32 as shown in FIG. From,
As shown in FIG. 4, a carry signal is output. The flip-flop 31 is reset by the output of this carry signal, and its output state is inverted, and as shown in FIG. 47 and FIG. A signal of "1" is output from the output terminal. Since the Q side output terminal of the binary flip-flop 35 outputs a signal of "1" as shown in FIG.
An output as shown in FIG. 10 is obtained and sent out from the switch control section 12 as a control signal _f2 .

That is, this control signal _f2 is output 4 seconds after the recording switch _S2 is operated, and
By outputting this control signal _f2 , a recordable state is achieved. In this way, for 4 seconds after operating the recording switch S ₂ , the buzzer sound is emitted as a confirmation sound to notify the start of recording, and the buzzer sound is emitted for 4 seconds after operating the recording switch S ₂ . Elapsed time is 0.5
It is displayed on the analog display section 51 every second.

When the control signal f ₂ is output, the semiconductor memory 19 receives write designation, the address section 16 outputs address information, and the I/O switching circuit 22 operates as an input circuit, and the A /D conversion circuit 17 and encoding circuit 1
8 becomes operational. In this state, you can play music that suits the user's preference from a radio receiver or the like by pointing into the microphone 25, or say the words that the alarm time means, such as "meeting", "meeting", "meeting", etc. Pronounce correctly.
Then, the audio signal sensed by the microphone 25 is converted into a digital quantity by the A/D conversion circuit 17, further encoded by the encoding circuit 18, and provided to the semiconductor memory 19. In this semiconductor memory 19, specified addresses are sequentially converted according to output information from the address section 16, and audio information is written to the specified addresses, so that predetermined music, "meeting", "meeting", etc. The audio is recorded.

That is, by outputting the control signal _f2 , the AND circuit 1
4 is de-gated. Since the AND circuit 14 is given a 1Hz signal as shown in FIG. 42, when the gate of the AND circuit 14 is released, the AND circuit 14 outputs a 1Hz signal as shown in FIG. signal is output. Therefore, "8" preset in the down counter 13 is subtracted by 1 each time the 1 Hz signal output from the AND circuit 14 is applied. The output content A of the down counter 13 is sent to the display control circuit 4. Since the display control circuit 4 is supplied with the Q side output signal of the binary flip-flop 10 and the control signal _f2 , the gate of the AND circuit 39 is released. Therefore, the output content A of the down counter 13
is sent from the display control circuit 4 via the AND circuit 39 and the OR circuit 42, and is applied to the analog display section 51. As a result, in the liquid crystal display section 5,
As shown in FIG. 6, the digital display sections 49 and 50 display the alarm time "12:35," and when the output content A of the down counter 13 is "8," the analog display section 51 All eight dot displays are lit, but every second that passes, the dot displays corresponding to the fixed displays "PM", "S", "F", etc. go out, and the down counter 13 is turned off. When the output content A reaches "5", as shown in FIG. 6, the fifth dot display from the left end in the figure lights up, and the remaining recording capacity of the semiconductor memory 19 is: Expressing this in time, it clearly shows that there are 5 seconds left. In this way, the remaining recordable capacity is optically displayed on the analog display section 51, so that recording can be performed while viewing this display.

When eight pulse signals are output from the AND circuit 14, the down counter 13 outputs the following:
As shown in FIG. 4, a borrow signal is output. This borrow signal is sent to the switch control section 12. Then, in the switch control section 12, the boro signal from the down counter 13 is sent to the OR circuit 3.
4, the output state of flip-flop 35 is inverted. Therefore, the Q side output signal of the flip-flop 35 becomes "0" as shown in FIG. 4, and accordingly, the output signal of the AND circuit 36 also becomes "0" as shown in FIG. 4, 10. . Therefore, the recording will end when 8 seconds have elapsed since the recording started.

When the alarm time is reached and the alarm signal AL is output from the matching circuit 7, the alarm signal AL is given to the OR circuit address section 16, causing the address section 16 to output address information, and the encoding circuit 20 and the audio signal synthesis circuit 21 are made operable. At this time, since the control signal f 2 is not given to the semiconductor memory 19 and the I/O switching circuit 22, the semiconductor memory 19 and the I/O switching circuit ₂₂ are not given the control signal f2.
9 receives a read designation, and the I/O switching circuit 22 operates as an output circuit. In this state, the audio information stored in the semiconductor memory 19 is sequentially read out in accordance with the address specification of the address section 16. The read audio information is encoded by the encoding circuit 20 and then sent to the audio signal synthesis circuit 21, where it is converted and synthesized into an audio signal, and then sent to the I/O switching circuit 22. The signal is sent to the amplifier 23 via the signal. The audio signal amplified by the amplifier 23 is sent to the speaker 25 via the gate circuit 24 whose gate is released by the output signal of the inverter 26, and is emitted as an alarm time notification sound. Note that if the recorded audio information is a predetermined song, this song is pronounced, and if the word is the meaning of the alarm time, the word, for example, "meeting" or "meeting" is pronounced.

On the other hand, the alarm signal AL enables the A/D conversion circuit 27 via the OR circuit 28. In this state, the volume signal amplified by the amplifier 23 is converted into a digital quantity by the A/D conversion circuit 27 and sent to the display control circuit 4. Since the alarm signal AL is applied to the display control circuit 4, the gate of the AND circuit 41 is released.
Therefore, the volume information from the A/D conversion circuit 27 is sent out from the display control circuit 4 via the AND circuit 41 and the OR circuit 42, and is given to the analog display section 51. Therefore, the level of the volume of the recorded content produced by each dot display on the analog display section 51 is displayed.

In this way, recording becomes possible 4 seconds after operating the recording switch S ₂ , and a confirmation sound notifying the start of recording is heard from 4 seconds before recording starts until recording starts. is sounded, and the remaining time until recording starts is displayed at the level. Therefore, the recording start point can be known aurally and visually, and recording can be performed effectively without wasting the recordable capacity. Also, while recording, the remaining recording capacity is displayed at the level, so while watching this display,
It is possible to record, eliminate recording omissions, and ensure reliable recording.

In each of the above embodiments, the alarm sound is sounded at a set time, but the present invention is not limited to this, and the alarm sound may be sounded at a set time on a specific day. When the time has elapsed, the sound may be emitted as a timer notification sound or as a time signal every hour on the hour.

Further, in each of the embodiments described above, the audio information recorded in the semiconductor memory is sounded only as an alarm sound, but the audio information may be arbitrarily read out and generated by an external operation switch.

Further, in each of the embodiments described above, the remaining recordable capacity is displayed in an analog level, but it may also be displayed digitally and numerically.

Furthermore, in each of the above embodiments, when the recorded content is pronounced,
Although the volume level is displayed, the volume level may also be displayed during recording.
