[Industrial applications]

 The present invention relates to a repetitive voicing device in a viewing facility or an audio / video (AV) device, and in particular, a "language" capable of repetitive voicing by being combined with an external device (VTR, audio device, so-called karaoke, TV callaque, etc.). The present invention relates to a repetitive voicing device in a viewing facility having a function of "learning" or "imitation practice of pronunciation".

[0002]

[Prior art]

 At present, the language learning machines on the market process direct audio frequencies by means of voice memory and reproduction ICs, and utilize the motor driving force by using a "tape" medium and a magnetic head inside the machine body. I repeat the vocabulary that I want to practice, but I cannot connect the external device to repeat the signal of the external device. However, most repetitive vocalization methods such as general VTRs, audio equipment, karaoke, and karaoke TV (hereinafter referred to as KTV) are performed by "rewinding and replaying" the tape. Although this method is unavoidable, it is useful for the user to listen to a number of sentences or phrases and learn the language or practice with vocalization, but the operation is complicated and the equipment is severely damaged. However, the tape is worn out relatively many times and the service life of the tape is shortened, and when the tape is barely exposed, the user mistakes the rewind stop timing in a timely manner to unnecessarily make the user feel uncomfortable or correct it. There is a problem that it takes time to save.

Also, the contacts d and e of the first relay switch (25) are opened, the contacts f and h of the second relay switch (27) and the contacts i and k of the third relay switch (28). Are conducting. Therefore, since all the signals coming into the device of the present invention bypass the voice generator (23) and directly go to each output terminal, even if the "pause" key is pressed at this time, the voice frequency signal is output from the voice generator (23). Since it cannot be broadcast, the operation of the entire system does not differ from general viewing equipment.

However, since the purpose of the present invention is "language learning" or other "pronunciation practice", first, the first sliding knob (2) is switched to the second position (4), and the device of the present invention is switched. When is set to the "learning" use state, the passage for advancing the pause signal to the pause control circuit (31) is conducted, and the pause signal enters the pause control circuit (31) to proceed with recording / recording. A control signal is generated at the output contact m or n in the playback selector (30) to control the voice generator (23) to the "recording" state or the "playing" state, and the device of the present invention is set to the "learning" state. To do. The situation in which the device of the present invention is used in combination with various external devices will be described in detail below.

(1) When used in connection with VTR First, the second sliding knob (5) is switched to the third position (6) so as to be controlled by the remote control signal of the VTR.

A. A. V. When there is no terminal; referring to FIG. 2 and also referring to FIG. 1 at the same time, as shown in the figure, the radio frequency input terminal (11) in the “repetitive vocalization device in the audio visual equipment” of the present invention is Connected to the radio frequency output, the radio frequency output terminal (12) is connected to the antenna input of the TV in the subsequent stage, and at this time, the third sliding knob (8) is switched to the fifth position (9). Then, the radio frequency / audio frequency selection switch (21) contacts a and b are conducted. When the radio frequency signal of the VTR is input to the radio input terminal (11) at this time, a part of the signal goes through the mixer (26) to the radio frequency output terminal (12) to provide the image and sound to the TV, The other part of the signal enters the radio frequency demodulator (20) and is demodulated into an audio frequency signal, and then enters the voice generator (23) through the contacts a and b of the radio frequency / audio frequency selection switch (21). Then, "normal", the voice generator (23) and the recording / playback selector (30) of the pause control circuit (31) are connected so that the contacts 1 and m are conducted, and the recording / playback selector (30) causes the voicemaker ( 23) continuously record the audio frequency signal coming from the radio frequency / audio frequency selection switch (21) for 20 seconds, and at the same time discard the previous old signal.

Then, when the "pause key" of the VTR remote controller is pressed, the remote control sensor (18) receives a pause signal and activates the pause control circuit (31) to activate the contacts in the recording / playback selector (30). The l and n are conducted, and the voice signal from the radio frequency / voice frequency selection switch (21) previously recorded by the voice generator (23) is repeatedly reproduced by the radio frequency modulator (24), During the pause, the pause control circuit (31) conducts the contacts d and e of the first relay switch (25) and the radio frequency modulator (24) comes from the voice generator (23) to duplicate the voice frequency. The signal is modulated into a radio frequency signal and is sent to the mixer (26) via the contacts d and e of the first relay switch (25). Also, during this pause, the signal at the radio frequency input terminal (11) only has a static image and does not contain audio, so the mixer (26) has a radio frequency signal containing duplicate audio frequency signals and still images. Send the signal to the radio frequency output terminal (12) and supply it to the input antenna of the TV, and listen to the duplicate sound while watching the still image when the user learns the words and sounds until the "pause" state disappears. be able to.

Is repeatedly reproduced and the contacts g and f of the second relay switch (27) are output from the first audio frequency output terminal (14), and at the same time, the radio frequency signal of the still image is input to the radio frequency input terminal. It sends from (11) to a radio frequency output terminal (12). In this way, the user learns words and sounds by listening to repetitive utterances while looking at the still image until the user releases the "temporary pause" state.

At this time, the third sliding knob (8) is switched to the sixth position (10) to bring the contacts a and c of the radio frequency / audio frequency selection switch (21) into conduction. "Normal", a part of the audio frequency signal reaches the voice generator (23) from the audio frequency input terminal (13) through the contacts a and c of the radio frequency / audio frequency selection switch (21), and the other part of the audio frequency signal. The audio frequency signal reaches the first audio frequency output terminal (14) from the audio frequency input through the contacts f and h of the second relay switch (27) to provide TV audio, and "normal" recording / At the output contact m of the reproduction selector (30), a control signal is generated so that the speech generator (23) records the audio frequency signal coming from the radio frequency / audio frequency selection switch (21) for 20 consecutive seconds and at the same time forward. Discard the old signal recorded.

When the "pause key" on the remote controller of the VTR is pressed, the remote control sensor (18) receives the pause signal and activates the pause circuit (31) to output the data in the recording / playback selector (30). A control signal is generated at the contact n, and at the same time, the contacts f and g of the second relay switch (27) are also conducted, and at this time, the audio frequency signal from the audio frequency input terminal (13) is not emitted. The image frequency signal of the still image is sent from the image frequency input terminal (16) to the image frequency output terminal (17), and the speaker 23 is activated by the control signal of the output contact n in the recording / playback selector (30). The voice frequency signal of the radio frequency / voice frequency selection switch (21) recorded previously is repeatedly reproduced, and the contacts f and g of the second relay switch (27) are connected to the first voice frequency output terminal 14 This allows the learner to hear overlapping voices while watching the still image on TV until the “pause” state is released.

The first flip-flop (550) of the latch (55) receives the control signal (53-12 waveform shown in FIG. 8) input to the second electric circuit (53) at the CLM (bar) pin. However, since the CLR, J, and K pins of the first flip-flop (550) are in contact with Vcc, the output pin Q, − of the first flip-flop (550) is input every time the control signal enters. Q modifies its output state once and transmits a High / Low status signal to the first NOR gate (552) and the second NOR gate (553), and further to the second flip-flop (551). The J pin is connected to Vcc, the K pin is connected to the ground, and the CLR pin is connected to the reset device, and the reset is controlled by the ground switch (556). Then, at the moment when the ground switch (556) is pushed down, a Low signal is output from the Q pin of the second flip-flop (551) and sent to the first NOR gate (552), and the remote controller is a series of plural sets at a time. Of the same pulse, and each pulse of each set is converted into a control signal through the second electric circuit (53). In addition, each control signal modifies the output state of the output pins Q and -Q of the first flip-flop (550), and therefore, when the output pin Q once turns to Low (at this time, the ground switch is depressed. Output from the first NOR gate (552) to the third NOR gate (554), and it outputs the Low signal to the WE (bar) pin of the memory section (54). A command is issued to activate the memory unit (54) to store the effective data formed by the pulse signal.

On the other hand, after resetting the ground switch (556) of the reset device to open, the CLR pin of the second flip-flop (551) gradually recovers to a high potential, and the original output becomes Low. A High signal is output from a certain Q pin to change the output of the first NOR gate (552) to Low, and then the output of the third NOR gate (554) is changed to High. Then, the memory unit (54) loses the write function, and at the same time, the Hi gh signal output from the Q pin of the second flip-flop (551) is also transmitted to the first NAND gate. Further, one input pin of the second NOR gate (553) receives the negative pulse signal output from the Q pin of the third electric circuit (560), and the other input pin of the first flip-flop (550). Connected to the Q pin, when the output of the Q pin is the Low signal, the second NOR gate (553) outputs the High signal, and the High signal output from the Q pin of the second flip-flop (551). Along with the signal, a Low signal is output from the first NAND gate (555) to activate the OE (bar) pin of the memory unit (54), and the stored effective data is output to Dout () of the memory unit (54). The ground switch (556) is open at this time, so the Q pin of the second flip-flop (551) is still connected to the High signal output. That.

The third electric circuit (560) of the comparison device (56) also receives the pulse signal from the remote control sensor (18), and outputs a High signal from the Q pin to the second NAND gate (563). Output to. In addition, the fourth electric circuit (561) receives the control signal (Low) input from the second electric circuit (53), and outputs the High signal from the Q pin of the fourth electric circuit (561) to the third signal. Output to the NAND gate ((564), and further, the XOR gate (562) outputs the valid data (Dout (bar) waveform shown in FIG. 8) and the first data output from the Dout (bar) pin of the memory section (54). 1 receives the effective data converted and output by the electric circuit (52) for comparison, and outputs the pulse signal indicated by 562-3 in FIG. 8 to output the Q pin of the third electric circuit (560). The output pulse signal (560-13 waveform shown in FIG. 8) is sent to the second NAND gate (563), and the second NAND gate (563) corresponds to the 560-13 waveform and its corresponding waveform. 562-3 waveform relative position ( Points shown) with each other compared with indicia, determining the output signal of the second NAND gate (563).

As a result of the above comparison, if the correct code has not entered, the second NAND gate (563) outputs the Low signal, and the Low signal causes the third flip-flop (565) to be output. After clearing, a Low signal is output from the Q pin of the third flip-flop (565) to the D pin of the fourth flip-flop (566), and a Low signal is output from the Q pin of the fourth flip-flop (566). It outputs to the third NAND gate (564) so that the output of the third NAND gate becomes a High signal, and the recording / playback selector (30) cannot be operated, and its Q (m), − The Q (n) pin becomes inoperative and the voice generator (23) cannot change its operating state.

Conversely, if the correct cipher is entered, the second NAND gate (563) outputs the Hi gh signal to the CLR pin of the third flip-flop (565), and at this time, the third flip-flop. (565) outputs a High signal to the D pin of the fourth flip-flop (566), and a High signal (combined with the High signal output from the -Q pin of the fourth electric circuit above) from the fourth flip-flop. ) Is output to the third NAND gate (564) and a Low signal is output from the third NAND gate (564) to activate the record / playback selector (30), and its Q (m), − The output state of the Q (n) pin is changed and input to the second flip-flop (551) of the latch (55), the second flip-flop (551) is locked, and the output of the Q pin is changed. The memory section (54) is held in the High state so that the memory section (54) can read and cannot write. And every time the recording / playback selector (30) receives the "Low" signal, its output pins Q (m) and -Q (n) change the state once (the above l, m and l, n). (As if the condition of the passage changed once), so that the "recording" and "reproducing" states of the voice generator (23) changed once.

Further, explaining the situation of the above comparison, when the correct code is input, the relevant positions of the 560-13 waveform and the corresponding 562-3 waveform of FIG. 8 (points shown by circles). As can be seen from the above, when each corresponding point is in the High state in the 560-13 waveform, the Low state is exhibited in 562-3, and accordingly, the output from the second NAND gate (563) is the High signal. And changes the state of the Q (m) and -Q (n) pins of the recording / playback selector (30). As can be seen from the above, when the stored pause signal enters the remote control sensor (18) again, all the operation states of “record” and “play” of the device of the present invention can be changed once. The purpose of can be achieved.

To explain one step further, when the remote control signal is stored, the following application is possible. If the vocalizer (23) is in the recording state without pressing the "pause" key, that is, the output Q (m) of the recording / playback selector (30) is Low and -Q (n) is High. is there. When the "pause" key is pressed the first time, the output Q (m) of the recording / playback selector (30) becomes High and -Q (n) becomes Low (that is, the above-mentioned 1, n passage), The voice generator (23) repeats the previously recorded voice. When the "pause" key is pressed the second time (that is, the "pause" is released), the output Q (m) of the recording / playback selector (30) becomes Low, and -Q (n) becomes High. The voice generator (23) will be in a recording state.

When the memory unit (54) is locked in the read-only state, the pulse signal input from the remote control sensor (18) is not the data stored in the memory unit (54) (that is, It is not a pause signal or a pause signal of a different code) and the output Q (m), -Q (n) of the recording / playback selector (30) in the comparison device (56) cannot be changed, that is, It does not work. Also, if the user replaces the VTR, audio device, karaoke, KTV, etc. with a new one, if the ground switch (556) of the reset device is directly pressed, it is updated according to the above-mentioned principle. Cryptographic signals can be stored and locked.

In addition, the repetitive voicing device in the audio-visual equipment of the present invention may further include an auxiliary power source in the pause control circuit to provide a power source necessary for locking the data in the memory unit. It is possible to prevent the data in the memory unit from being lost after the entire device is closed, and the trouble of having to reset the data each time the device is started.
