[Action]

 When recording, the recording operation is performed and sound such as voice or music is input from the microphone. By this acoustic input, the acoustic signal output from the microphone is recorded in the semiconductor memory circuit. After recording in this way, the clock is set to a predetermined set time. For example, in the case of an analog clock, the time setting hand is set so as to match the alarm time.

When the time advances and the clock reaches the set time, the acoustic signal recorded in the semiconductor memory circuit is read in response to the clock operation, and this acoustic signal is sent to the speaker for acoustic output. . Such sound output is repeated every time the clock reaches the set time unless the recording is changed. When changing the acoustic output, a recording operation is performed to record the sound such as new voice or music in the semiconductor memory circuit.

When a sound input / output device that can be used both as a microphone and a speaker is used, a sound such as voice or music is input to this sound input / output device during a recording operation. As a result, the acoustic signal is recorded in the semiconductor memory circuit by the microphone function of the acoustic input / output device. The acoustic signal thus recorded in the semiconductor memory circuit is read out in response to the clock setting time and is acoustically output by the speaker function of the acoustic input / output unit.

As described above, the timepiece of the present invention can arbitrarily record a desired sound such as voice and music, and at the set time of the timepiece, the sound can be reproduced and sounded. It can be used as an alarm clock by recording voices and light music such as "Are you" and "It's time", and can also be used as a clock to record a voice message and present it as a souvenir. be able to.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of an analog timepiece embodying the present invention as seen from the front side, and FIG. 2 is a perspective view of the same timepiece as seen from the back side. As is well known, the timepiece 10 is provided with a long hand 10a, a short hand 10b, and a time setting hand 10c. A speaker 11 is provided on the front surface, and operation and non-operation of the sound recording / reproducing apparatus are provided on the side surface. Each switch knob 12 for selection is provided.

Further, on the back side of the timepiece 10, a time setting knob 13 for adjusting the long hand 10a and the short hand 10b, and a time setting knob 14 for setting a turning position of the time setting hand 10c and setting a sound generation time point. In addition, a microphone 15, a recording knob 16, and a recording confirmation knob 17 are provided.

FIG. 3 is a circuit diagram of the sound recording / reproducing apparatus built in the above-described timepiece 10. This device circuit is provided with a known non-volatile audio analog memory, or a memory 18 such as EEPROM or DRAM (hereinafter simply referred to as a semiconductor memory circuit) 18. The semiconductor memory circuit 18 has a recording / reproducing function for about 12 to 20 seconds. An acoustic signal output from the microphone 15 is recorded in the semiconductor memory circuit 18, and the acoustic signal is read from the semiconductor memory circuit 18 and output as an acoustic signal from the speaker-11.

Specifically, the semiconductor memory circuit 18 includes an amplifier circuit that amplifies the acoustic signal output from the microphone 15, and a processing circuit that processes the amplified acoustic signal so that the amplified acoustic signal can be recorded in the semiconductor memory. And a processing circuit for converting the recording signal read from the semiconductor memory into an acoustic signal and sending it to the speaker 11.

Further, the semiconductor memory circuit 18 described above becomes a recording mode by closing a switch 16a for supplying a power supply voltage from a battery power supply 19 and a memory command switch 16b. That is, the switches 16a and 16b are interlocking switches that are closed together by pressing the recording knob 16, and the switches 16a and 16b are closed to shift to the recording mode.

Further, since the semiconductor memory circuit 18 is in the reproduction mode only by applying the power supply voltage, the transistor 20 for switching operation is turned on to shift to the reproduction mode. The transistor 20 is turned on by closing the response switch 21 provided in the timepiece interlocking mechanism.

That is, to the base circuit of the transistor 20, the response switch 21 and the switch 12a which is closed by the operation of the switch knob 12 are connected, and the response switch 21 is closed when the switch 12a is closed. At some times, the transistor 20 is turned on, and the semiconductor memory circuit 18 is in the reproduction mode.

The switch 17a connected between the emitter and collector of the transistor 20 is a switch that is closed by pressing the recording confirmation knob 17, and the switch 17a is closed to read the record of the semiconductor memory circuit 18 and record it. Check the contents.

FIG. 4 is a configuration diagram showing an example of a timepiece interlocking mechanism having the response switch 21. As shown in the figure, a switch drive gear 23 is rotatably supported by fixed plates 22a, 22b made of an electrically insulating material and provided at predetermined intervals in the timepiece, and is integrally provided on the gear 23. A concave groove 23b is provided in a part of the disk-shaped portion 23a.

Further, a movable contact piece 24 made of an elastic conductive plate having one end fixed to the fixed plate 22a is provided, and a tip end portion 24a of the movable contact piece 24 is brought into contact with and separated from a fixed contact piece 25 provided on the fixed plate 22b. Thus, the response switch 21 is operated.

Further, in the middle of the movable contact piece 24, a connecting plate 26 provided with a protrusion 26 a is fixed, and a switch driving is performed in a communication hole 27 formed in the movable contact piece 24 and the connecting plate 26. The support shaft 23c of the gear 23 is loosely inserted. Then, the movable contact piece 24 and the connecting plate 26 are constantly pressed in the direction of the switch drive gear 23 by the expanding force of the spring 28, and the protrusion 26a normally contacts the surface of the disk-shaped portion 23a as shown in the figure. In this state, the movable contact piece 24 is separated from the fixed contact piece 25.

The switch driving gear 23 described above is driven and rotated by an interlocking gear 29 that interlocks with the time feeding mechanism of the minute hand 10a and the minute hand 10b of the timepiece 10. The switch drive gear 23 is interlocked so as to make one revolution in 24 hours (or 12 hours), and the groove 23b turns to the position of the protrusion 26a according to the set time, and at this time, the protrusion 26a moves in the recess 23b. Then, the tip end portion 24a of the movable contact piece 24 comes into contact with the fixed contact piece 25 by this operation, and the response switch 21 is closed.

The position of the recess 23b of the switch drive gear 23 is set in advance by rotating the interlocking gear 30 according to the time setting of the time setting hand 10c. Note that the interlocking system between the interlocking gear 29 and the time feed mechanism of the clock 10 is cut off while the position of the recess 23b is preset in this way.

The recording / playback operation of the above-described timepiece 10 will be described. First, for example, the switch knob 12 is slid downward as shown in FIG. 1 to close the switch 12a. When recording, the recording knob 16 is operated to close the switches 16a and 16b, and in this state, sound is input from the microphone 15.

As a result, the acoustic signal output from the microphone 15 is input to the semiconductor memory circuit 18, and this acoustic signal is amplified and signal-processed and recorded in the semiconductor memory. After recording the acoustic signal in the semiconductor memory circuit 18, the operation of the recording knob 16 is stopped and the switches 16a and 16b are opened. When confirming the recording, the recording confirmation knob 17 is operated to close the switch 16a. As a result, the audio signal is read from the semiconductor memory circuit 18 and is acoustically output from the speaker-11, so that the recorded content can be confirmed.

On the other hand, with respect to the timepiece 10, the time setting hand 10c is turned to set the sound reproduction time point of a desired time. As described above, the switch drive gear 23 is rotationally driven according to this time setting, and the recess 23b is preset to a predetermined turning position. At this time, the response switch 21 is open.

With the above, the setting at the time of sound reproduction is completed. After that, since the switch driving gear 23 rotates with the progress of time of the minute hand 10a and the minute hand 10b of the timepiece 10, when the sound reproduction point is reached, the protrusion 26a falls into the recess 23b and the movable contact piece 24 is fixed. It contacts the contact piece 25. As a result, the response switch 21 is closed, the transistor 20 is turned on, the power supply voltage is applied to the semiconductor memory circuit 18, the acoustic signal recorded in the semiconductor memory circuit 18 is read, and the acoustic output is made from the speaker 11. To be done.

The protrusion 26a that has fallen into the recess 23b escapes from the recess 23b after a certain period of time due to the rotation of the switch drive gear 23, and opens the response switch 21, but the response switch 21 opens to open the transistor. All the acoustic signals recorded in the semiconductor memory circuit 18 before the return to OFF of 20 are acoustically output from the speaker 11.

On the other hand, if the switch knob 12 is slid upward in FIG. 1 to open the switch 12a, the transistor 20 remains off regardless of whether the response switch 21 is closed. When the sound is reproduced, the reproduction operation is not performed.

FIG. 5 shows an embodiment provided with a timer-31 for counting the reproduction time from the closing time of the response switch 21. In this embodiment, once the response switch 21 is closed, the transistor 20 is turned on while the timer 31 is counting regardless of whether the switch 21 is open or closed. Playback operation is performed. By providing a reproduction stop switch 32 and closing the switch 32, the reproduction operation can be stopped while the timer 31 is counting.

The embodiment shown in FIG. 6 is provided with a sound input / output device 33 that can be used both as a microphone and a speaker, and has a configuration in which the changeover switch 34 is switched to input sound and output sound. The change-over switch 34 is always turned on to the terminal a, and in this state, the sound signal is input and the sound signal output from the sound input / output unit 33 is recorded in the semiconductor memory circuit 18 as in the above embodiment. When the timepiece 10 advances to the point of sound reproduction, the changeover switch 34 is changed over to the terminal b as the response switch 21 is closed, and the recorded contents of the semiconductor memory circuit 18 are outputted as sound from the sound input / output unit 33.

FIG. 7 shows an example implemented in a digital time display clock (digital clock) 35. Since the digital timepiece 35 is configured to generate an alarm signal at a preset clock time, the switch element such as the transistor 36 is turned on by the alarm signal, and the transistor 20 is turned on by turning on the switch element. It is configured to With this configuration, it is possible to arbitrarily record a desired sound in the digital timepiece 35 in the same manner as described above and also to acoustically reproduce at a preset time of the timepiece.

Although the respective embodiments have been described above, the present invention can also be applied to a wristwatch or the like in the same manner, and when applied to a digital timepiece, the setting of the hour, minute and time is set. Not only this, but the year, month, day, and hour and minute may be set in advance, and the reproduction operation may be performed at this set time. Although the semiconductor memory circuit 18 having the analog recording structure is used in each of the above-described embodiments, the present invention can be similarly implemented by using the semiconductor memory circuit having the digital recording structure.
