DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 A case where the present invention is applied to a communication karaoke apparatus will be described. Generally, in a communication karaoke apparatus, karaoke data received from a communication line is separated into video data and music data. The video data is lyrics characters and background images, and the music data is MIDI
The video data is sent to the display control circuit, the display timing is adjusted, and the video data is displayed on the screen of the television. Speakers and CRTs for screens use existing televisions, etc.
The DI data is reproduced by a synthesizer for a sound source into performance sound data, pitch data, and tempo data of a musical instrument. When singing a song, the user's singer sings into the microphone while listening to the performance from the speaker while listening to the lyrics displayed together with the background image on the screen. Here, the performance reproduction circuit of the karaoke apparatus will be omitted, and a portion relating to voice control will be described.

The control target of the voice control includes, for example, input of the number of the requested music, adjustment of the singing speed tempo, setting of the pitch of the voice, and the like. In this embodiment, a voice control transmitting circuit is provided on the microphone side held by the singer, and a receiving circuit is provided on the karaoke apparatus side. FIG. 2 is a block diagram of the microphone body 10 of the present invention.
The microphone body 10 includes a control signal generating circuit 2, a signal mixing circuit 3, and a control switch 4 in addition to the ordinary microphone 1.

The microphone 1 and the control switch 4 are connected to the microphone body 1
It is exposed on the zero surface, allowing input of sound waves and manual operation. While the control switch 4 is being pressed, the audio signal V input from the microphone 1 and the control signal Q from the control signal generation circuit 2 are mixed by the signal mixing circuit 3 so that the code 5
Sent above. Control signal Q that does not normally enter from microphone 1
(Control signal) is mixed with the audio signal V so as to be put on a cord (cable). An output terminal 6 is connected to the code 5, and an output terminal 12 can be connected to an input terminal of the karaoke apparatus 20, and a necessary battery and the like are built in the microphone body 10.

A control unit for processing a control signal by voice is added to the karaoke apparatus to be controlled. FIG. 1 is a block diagram of a circuit necessary for voice control provided on the karaoke apparatus side. The karaoke apparatus 20 includes a microphone input terminal 15 of two circuits, respective amplifiers 16, a volume 17, a low-pass filter 18, and a two-circuit built-in converter 19 to which these are merged.
Two microphones can be used for two circuit input terminals 15 (receiving circuits). Explaining one circuit as a representative, the low-pass filter 18 is a filter that passes the audio signal V: 0 to 20 KHz of only the graph B in the graph A of FIG. Where the analog signal is converted to a digital signal for subsequent processing. The same applies to the other circuit.

The outputs of both amplifiers 16 are also sent to a signal selection circuit 21, and the signal from one amplifier 16 selected by the signal selection circuit 21 is sent to a high-pass filter 22. The high-pass filter 22 is a filter that passes the control signals 20 K to 100 KHz of only the graph C in the graph A of FIG. 3, and the passed control signal Q is sent to the detection circuit 23. The audio signal V of the two circuits from the converter 19 and the control signal Q from the detection circuit 23 are sent to the audio signal processing block 25.

The audio signal processing block 25 comprises a first electronic switch 26, a second electronic switch 27, an initial mixer 28, a switching circuit 29, a command judging circuit 30, and an audio effect circuit 3.
And 1. Here, the initial mixer 28 and the sound effect circuit 31 are ordinary karaoke circuits for processing a singing signal. One audio signal V from two-circuit converter 19
To the first electronic switch 26 and the other audio signal V to the second electronic switch 27, respectively. The existence signal T of the control signal Q from the detection circuit 23 is sent to the switching circuit 29,
The switching circuit 29 controls switching while identifying the first electronic switch 26 and the second electronic switch 27 in synchronization with the position signal of the signal selection circuit 21.

The first electronic switch 26 and the second electronic switch 27 normally send the audio signal V from the converter 19 to the initial mixer 28, but send the instruction signal from the switching circuit 29 to the instruction determination circuit 30 when there is an instruction from the switching circuit 29. Is controlled. When the audio signal V is input from the first electronic switch 26 and the second electronic switch 27 at the same time, the initial mixer 28 mixes these signals and sends them to the audio effect circuit 31. The sound effect circuit 31 adds an echo effect or the like to the singing signal of the sound signal V, and sends it to the mixing circuit 36. The mixing circuit 36 mixes the singing signal of the audio signal V with the performance of the musical instrument from the performance sound generating circuit 37 and sends it to the left and right output terminals 38.

The signal selection circuit 21 is also an electronic switch,
The circuit A of one amplifier 16 and the circuit B of the other amplifier 16 are switched at short time intervals by a switching signal from the switching circuit 29 (to constantly monitor whether or not the control signal Q is generated). The detection circuit 23 detects the control signal Q and generates a signal T. The signal T serves as a switching command for the switching circuit 29. The switching circuit 29 selects the first electronic switch 26 or the second electronic switch 27. Output a signal.

The instruction judging circuit 30 includes a first electronic switch 26.
Alternatively, the words “3”, “early”, “low” and the like in the audio signal V input from the second electronic switch 27 are determined from the waveform, and the corresponding command signal is output to the main controller 32. The main controller 32 receives a request signal from a remote controller (not shown) or the like.
5 can be entered. The main controller 32 converts the command signal from the command determination circuit 30 into characters, displays, for example, a request number or the like on a display screen 33, and sends commands to various I / Os 34.

Now, it is assumed that two microphone bodies 10 of FIG. 2 are connected to both microphone terminals 15 of the karaoke apparatus 20 of FIG. 1, respectively. The audio signals V from both microphone bodies 10 are sent to corresponding volumes 17 from corresponding amplifiers 16. From each volume 17 to each low-pass filter 18,
The audio signal V is constantly sent to the first electronic switch 26 and the second electronic switch 27 via the converter 19.
While holding down the control switch 4 of the microphone pair 10, press the microphone 1
Orally, the control signal generating circuit 2 generates a relatively high-frequency control signal Q at the same time as the relatively low-frequency audio signal V, and these are mixed by the signal mixing circuit 3 and transmitted through the code 5. The signal is sent to the signal selection circuit 21 through the microphone terminal 15 and the amplifier 6 of the karaoke apparatus 20.

The signal selection circuit 21 periodically selects the first microphone amplifier 16 and the second microphone amplifier 16 alternately, and sends the selected signal to the high-pass filter 22. It also outputs an identification signal (selection positions A and B) indicating which microphone pair 10 is selected. In the micro time, the selection period is long enough to detect the control signal Q in the audio signal V. The high-pass filter 22 removes the audio signal V from the low-frequency signal, leaving only the high-frequency control signal Q in the graph C in FIG. 3. The detection circuit 23 determines the presence or absence of the control signal Q. The presence / absence determination (detection) signal T and the microphone identification number N (corresponding to the selected position A or B) are sent to the switching circuit 29 of the audio processing block 25.
When the control signal Q is detected at one microphone 1 (corresponding to the selected position A or B), the switching circuit 29 fixes the selection of the signal selection circuit 21 to the state of A of the one amplifier 16.

The switching circuit 29 places a priority on the control switch 4 of the microphone body 10 based on the identification number N. Based on the identification number N, the switching circuit 29 switches the first electronic switch 26 to the C state for connecting to the command determination circuit 30 and switches the other electronic switch 26 to the second electronic switch. The switch 27 is fixed to the state E (no change in normal continuation) in which it is connected to the initial mixer 28. The audio signal V containing the control signal Q enters the command determination circuit 30. There, it is determined whether it is a singing voice or a command voice. If it is a command voice, it is displayed on the display screen 33 according to the command and controls various I / Os 34. An audio signal V from the other microphone body 10 is sent from the initial mixer 28 to an audio effect circuit 31 of a normal karaoke circuit, and is used as a singer's voice.

The graph of FIG. 3 shows how the audio signal V from the microphone 16 and the control signal Q from 2 are divided. Thereafter, as long as the control signal Q is generated from one of the microphone bodies 10, the signal selection circuit 21 is fixed at A and the selection state of the first switch 26 is fixed at C. As a result, the selected state of the second switch 27 is also fixed to E. Therefore,
The voice of the other microphone 2 is ready to sing a karaoke song, and the voice of the one microphone 1 is a signal for command determination.

The command determining circuit 30 determines a corresponding command from the voice signal V of the command language and waveform data of a predetermined word, and sends it to the main controller 32. The main controller 32 determines whether or not the command can be executed in the current state. If possible, the command is executed. If the command cannot be executed, the command is not accepted. That is, when the request number is uttered as “queue, cue, cue, cue,” toward the microphone 1 with the control switch 4 kept pressed, for example, “9999” or the like is displayed on the display screen 33 and visually confirmed. You can order songs that have been confirmed as pronounced. Similarly, it is possible to lower the playing speed by sounding "change tempo, slower", sound "higher pitch", and request a melody of a lower tone. The present invention is not limited to a communication karaoke apparatus, but is applicable to a stationary karaoke apparatus, and the microphone may be a wireless type without a cord.

As described above, the communication karaoke device side, upon receiving the control, immediately starts accepting the control operation of the device. The microphone 1 can be shared with a control signal compatible product and can be realized with a simple circuit. Even during the performance, voice control can be performed with the other microphone 1. If you do it by voice, you can operate without staring at the request number on the screen. The karaoke device can be smoothly controlled while visually confirming the response to the screen instruction.
