It relates to a device that outputs a predetermined portion mixed with external sounds, handclaps, etc.

(Prior Art) In conventional mechanical clocks of this type, when the hour strikes, the dolls operate in time with a predetermined musical piece.
When the song ends, the doll also stops.
The same action was repeated every hour on the hour.

(Problems to be solved by the invention) In the above-mentioned conventional mechanical clock, the audience simply sees and hears the puppet's movements and the music being played, and it is also difficult to easily change the puppet's movements and the music being played. Because I couldn't do it, it became monotonous, and I found myself giving up after watching it a few times.

The purpose of this invention is to mix external sounds such as voices and handclaps into predetermined parts of the performance music, thereby creating changes in the performance music, and to improve the taste of the performance by allowing the audience to participate. Our goal is to provide a mechanical clock that you will never tire of.

A mechanical clock comprising a decoration drive circuit that outputs a drive signal in response, a decoration such as a doll that operates when a drive signal is input, and a performance signal output circuit that outputs a performance signal when an hourly signal is input. It is in.

This external sound mixing device also includes a control circuit that outputs a switch signal corresponding to a predetermined part of a performance piece in response to an hour signal and a performance signal, and a control circuit that detects an external sound and outputs an external sound in response to a switch signal. an external sound detection circuit that outputs a signal, a volume balance variable circuit that inputs a performance signal and an external sound signal and outputs a mixed signal that mixes the external sound with the performance song with a volume balance that corresponds to the level of the external sound; It consists of a sound generation circuit that inputs a mixed signal and generates a performance song and an external sound.

(Function) In the external sound mixing device of the present invention, the control circuit outputs a switch signal corresponding to a predetermined portion of the performance signal while the hour signal is being generated. The external sound detection circuit that receives this switch signal applies the external sound at this time as an external sound signal to the volume balance variable circuit. The external sound signal and performance signal are applied to the volume balance variable circuit, which changes the volume balance of the external sound and performance music according to the level of the external sound and outputs it as a mixed signal. The sound generation circuit simultaneously generates the external sound and the performance song with a volume balance according to the mixed signal.

Reference numeral 60 denotes a sound generation circuit, which includes an amplifier 62 that amplifies the mixed signal MX, and a speaker 64 that receives the output signal of the amplifier 62 and generates sound.

Next, the operation of the mechanical clock constructed as described above will be explained.

First, when it is on the hour, the hour signal _T1 from the hour detection circuit 4 becomes H level, and the decoration drive circuit 6 which receives this signal applies a drive signal to the decoration 8. Therefore, the decoration 8 starts an operation such as, for example, the stage protrudes and a doll appears, and when the predetermined operation is completed, the decoration drive control circuit 6 stops in response to the detection signal from the decoration 8.

On the other hand, at the same time as the movement of the decorative body 8, H
In response to the level hourly signal _T1 , the audio deck 12 also operates and outputs a signal of the music to be played. This signal is amplified by an amplifier 14 and output as a performance signal M.

This performance signal M is applied to a comparator 20, which detects whether or not it is equal to or greater than a set value.
For example, the comparator 20 detects a signal equal to or greater than a preset value in the performance signal M at the beginning of a performance of three pieces, number 1 through number 3.

When the comparator 20 detects, for example, the beginning of a song, its output signal goes high, and a pulse is output from the one-shot circuit 22 in synchronization with the rising edge of the signal. This pulse is generated at its output via the AND gate 24, which has already been opened by the hour signal _T1 ,
Applied to clock input C of FF26. As a result, the signal R from the output Q of the FF 26 becomes H level, which resets the hour detection circuit 4 and is applied to the input A of the monomulti 28.

When the H level signal R is applied to the input A of the monomulti 28, the output Q is set to the H level for a certain period of time. At this time, if the song number selection switch _S1 is on and the AND gate 34 is open,
The H level signal from the output Q of the monomulti 28 is generated at the output of the AND gate 34 and further generated as the signal S via the OR gate 40.

When this signal S becomes H level, the analog switch 50 to which this signal S is input is turned on. Therefore, when a voice, clap, etc. is input from the microphone 46 at this time, that signal is generated as an external sound signal OS via the analog switch 50.
The signal is applied to the level detection circuit 54. This level detection circuit 54 outputs a signal corresponding to the level of the external sound signal OS, and the decoder 56 which inputs this signal outputs its code signal.

A multiplexer 58, which receives the signal from the decoder 56, changes the volume balance of the performance signal M and the external sound signal OS according to the signal and outputs the same.
For example, when the external sound signal OS is input, the volume of the performance signal M is lowered and the external sound signal OS is mixed and output, and when the external sound signal OS is not input, the performance signal M is output at the maximum volume. and,
The sound generation circuit 60 to which this mixed signal MX is input generates the performance music and the external sound at respective set volumes.

Further, as described above, when the output Q of the monomulti 28 is at the H and L level for a predetermined period of time and then returns to the L and H level, the monomulti 30 is activated in response to the H level signal from the output. The output Q is set to H and L levels respectively for a predetermined period of time. At this time, if the song number selection switch S ₂ is in the ON state, the AND gate 36 is in the open state, and the H level signal from the output Q of the mono multi 30 is generated at the output of this AND gate 36. This occurs in the output signal S of the OR gate 40. Therefore, the external sound and the performance music are mixed and output in the same manner as in the operation described above.

Furthermore, after a predetermined period of time has passed, this monomulti 30
When the output Q, returns to the L, H level, the monomulti 32, which inputs the H level signal from the output Q to the input A, changes the output Q, to the H, L level. If the song number selection switch _S3 is in the ON state when the signal from this output Q becomes H level, the AND gate 38 becomes the H level signal from the output Q of the mono multi 32 in the open state. The signal S is generated at the output of the switch signal S via the OR gate 40. Therefore, in this case as well, the external sound and the performance music are mixed and output, similar to the operation described above.

After a predetermined period of time has elapsed, the output Q of the monomulti 32 returns to L and H levels, respectively, and a pulse is output from the one shot circuit 42 to which the H level signal from the output is input, and the FF 26 is reset.

In this way, the monomultis 28 to 32 sequentially switch their output states, and the timing of the switching is set to the timing when the number of the performance song changes, etc.

According to the above operation, by turning on a desired switch among the song number selection switches S ₁ to _{S 3} in advance, when the output state of the mono multi 28 to 32, that is, the song number is changed, external sound is output for a predetermined period of time. It will be in a state where it will be mixed with the performance song.

Incidentally, when the song number selection switch _S0 is operated, the switch signal S becomes H level regardless of the output status of the mono multiplayer 28 to 32, so that it becomes possible to mix external sounds throughout the performance song.

(Effects of the invention) According to the invention, external sounds such as voices and handclaps can be mixed into the music to be played, so it is possible to vary the music to be played, improve the hobby, and make it enjoyable for a long time. We can provide mechanical clocks without
