Description

[Detailed description of the invention] (Industrial application field) The present invention provides a microphone amplifier capable of continuously adjusting a pitch and a sound quality, and a play to be described below using the microphone amplifier. New device.

(Prior Art) As a conventional recreational device, a so-called karaoke device for singing along with a sound without voice (accompaniment), or the state of a play is projected on a screen of a television monitor, etc. 2. Description of the Related Art There is known a device for performing a play by speaking dialogue in accordance with movement (hereinafter referred to as a "shibaoke device"). In addition, microphone amplifiers that can adjust the pitch of accompaniment sounds by adjusting the frequency of an audio signal for use in a karaoke device or the like have been conventionally known.

(Problem to be Solved by the Invention) A new device to which the microphone amplifier of the present invention is applied (hereinafter, referred to as “the present device”) performs a play in a completely different way from the conventional Shibaoke device. That is,
In the Shibaoke device, the hero to be played is directly displayed on the screen, etc., and only the words are spoken in accordance with the movement of the hero's mouth, whereas this device is the viewpoint of the hero to be played or An image is made from the viewpoint behind this hero, so that only the actor acting as the hero's opponent is displayed on the screen etc., the hero's figure does not appear at all on the screen, or the back figure or part of the body etc. (Hereinafter, this format is referred to as "first-person format"). According to this first-person form of the present apparatus, the actor of the present apparatus, because the hero to be performed does not appear on the screen,
It is completely different from the case of the Shibaoke device, for example, in front of the opponent played by a famous actor or the like, the image can be more inflated, and the role can be completely fulfilled and played.

On the other hand, there are individual differences in human voices, and depending on gender, age, etc., not only the pitch but also the sound quality varies, such as a thick voice, a thin voice, a clear voice, or a squashed voice. Therefore, if the actor can adjust the sound quality of the voice speaking the dialogue by the present device,
When playing a role close to age, etc., you can play with a voice that matches the role, and a role far from yourself,
For example, it is possible for an old man to play a role of a young man or for a man to play a role of a woman, and to play the role without discomfort. Can be.

However, the conventional microphone amplifier used in a karaoke apparatus or the like can only adjust the pitch of the accompaniment sound, but cannot adjust both the pitch and the sound quality of the voice. Therefore, when the above-described conventional microphone amplifier is used in the present apparatus, the pitch and sound quality of one's own voice are generated as they are without being changed, so that when playing a role far from the user, a sense of incongruity occurs in the voice, and The range is limited and the above-described first-person version of the device cannot be fully utilized.

The present invention has been made to solve such a problem, and an object of the present invention is to provide a microphone amplifier capable of continuously adjusting the pitch and sound quality of a voice as desired. It is another object of the present invention to provide a device capable of performing a play by changing the pitch and sound quality of the performer's voice according to the selected role by using such a microphone amplifier.

(Means for Solving the Problems) In order to achieve the above object, a Shibaoke entertainment set of the present invention generates a microphone that supplies an audio signal of an actor to a microphone amplifier, a video signal and an audio signal,
A laser disk player that supplies the generated audio signal to the microphone amplifier; a video playback unit that plays back a video signal input from the laser disk player on a screen in a first-person format; Frequency adjusting means for adjusting the frequency of the audio signal input from the microphone for adjusting to the pitch of the hero not projected on the screen, and the sound for adjusting the sound quality of the actor to the sound quality of the hero not projected on the screen Frequency characteristic adjusting means for adjusting the frequency characteristics of the signal and distortion adjusting means for adjusting the distortion of the audio signal; and outputting the audio signal adjusted by the frequency adjusting means, the frequency characteristic adjusting means and the distortion adjusting means. Sound means for reproducing an audio signal input from the microphone amplifier. It is obtained by a reproducing means.

(Operation) According to the above Shibaoke entertainment set, the video signal from the laser disk player is displayed on the screen of the video reproducing means in a symmetrical form, and the voice signal of the performer input from the microphone is converted to the frequency of the micron amplifier. The frequency, that is, the pitch, is adjusted by the adjusting means,
The pitch of the actor is adjusted to the pitch of the hero, and the sound quality is adjusted by the frequency characteristic adjusting means and the distortion adjusting means.The sound quality of the actor is adjusted to the sound quality of the hero, and the adjusted audio signal and the sound from the laser disc player are adjusted. The signal is generated from the sound reproducing means, and the performer can produce a play.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 shows the basic overall configuration of the present device incorporating the microphone amplifier of the present invention. In the figure, reference numeral 1 denotes a microphone amplifier, which is connected in parallel to a laser disk player (hereinafter referred to as "LDP") 2 and one or two microphones 3 (only one is shown), and plays background sound of the play from LDP 2. , The voice of the performer's dialogue is input from the microphone 3 as an audio signal. The microphone amplifier 1 has an audio signal adjustment function to be described later. The microphone amplifier 1 outputs an audio signal from the LDP 2 to the monitor 4 and adjusts an audio signal input to the microphone 3, that is, the voice of the performer. The output audio signal is output to the monitor 4. LDP2 is also connected to monitor 4,
The video signal is output to the monitor 4. This image is in the first-person format described above, which is a feature of the present apparatus. The monitor 4 displays an image on the screen based on the image signal from the LDP2, and at the same time, the microphone amplifier 1
The sound is generated based on the sound signal from the computer. That is, in this embodiment, the monitor 4 constitutes a video reproducing unit and an audio reproducing unit. Therefore, the actor of the present apparatus can play the role by saying words while watching the monitor 4.

FIG. 2 shows an example of the microphone amplifier 1. The sound adjustment panel 10 has six adjustment knobs, namely a frequency adjustment knob 11, a frequency characteristic adjustment knob 12, a distortion adjustment knob 13, a reverberation level adjustment knob 14, A laser volume control knob 15 and a total volume control knob 16 are provided.

The frequency adjustment knob 11 and the frequency characteristic adjustment knob 12 constitute a frequency adjustment unit and a frequency characteristic adjustment unit, respectively, and by operating the frequency adjustment knob 11 and the frequency characteristic adjustment knob 12, the frequency and the frequency characteristic of the audio signal from the microphone 3 are converted into a known digital signal processing. To adjust continuously. For example, when the position of the frequency adjustment knob 11 is set to the center position in FIG.
The frequency of the input audio signal is maintained as it is,
The frequency is higher when set to the lower side, lower when set to the lower side, and is continuously adjusted. Since the pitch changes according to the change in the frequency, the operation of the knob 11 causes the microphone 3 to change.
Can continuously adjust the pitch of the performer's voice input from.

When the position of the frequency characteristic adjustment knob 12 is set to the center position in the figure, as shown in FIG.
The frequency characteristic is maintained in a so-called flat state. Hi
When set to the gh side, as shown by the broken line in FIG. 3 (b), the center frequency (point A in FIG. 3) of the frequency range for increasing the level is further increased and the bandwidth (width B in FIG. 3) is increased. ) Is narrowed, the treble is enhanced and the sound is adjusted to a thinner and clearer voice. On the other hand, when set to the low side, the frequency range where the level is increased as shown by the solid line in FIG. 3 (b) By lowering the center frequency (point A 'in the figure) and widening the bandwidth (width B' in the figure), the bass is enhanced and the voice is adjusted to a thicker voice. Therefore, by operating the knob 12, it is possible to continuously adjust the thickness and fineness of the voice by the audio signal. The adjustment of the frequency characteristics may be performed by simultaneously changing the center frequency and the bandwidth of the frequency range in which the level is to be increased, or by changing the magnitude of the level (C in the figure) or by combining these. You may go.

Further, the distortion adjustment knob 13 constitutes distortion adjustment means, and is used for continuously adjusting the manner of distortion of the audio signal by digital signal processing by the operation thereof. This takes into account that voice quality is slightly different depending on the manner of distortion even if the frequency and frequency characteristics of the audio signal are the same. In this embodiment, when the position of the distortion adjustment knob 13 is set to the center position, no distortion is adjusted, and when the distortion adjustment knob 13 is set to the plus (+) side, as shown in FIG. The upper and lower peaks of the waveform are sliced symmetrically, so that a so-called odd-wave distortion is generated to make the sound of the nose knob relatively, while when set to the minus (-) side, as shown in FIG. In addition, one of the upper and lower peaks of the waveform of the audio signal is sliced asymmetrically, so that a so-called even-numbered harmonic is generated to make the sound different again. Therefore, by operating the knob 13, the manner of distortion of the audio signal can be continuously adjusted between the odd-wave distortion and the even-wave distortion to finely adjust the voice quality.

The reverberation level adjustment knob 14 continuously controls the reverberation of the voice, so-called echo, the laser volume adjustment knob 15 controls only the volume of the audio signal from the LDP 2, and the total volume control knob 16 controls the overall volume. Knob for adjustment.

As described above, the present invention has been described based on the embodiments. However, the present invention is not limited thereto, and can be implemented in various modes. For example, while the microphone amplifier of the present invention is intended for use in the present device, it is clear that the same can be applied to a conventional Shibaoke device. In this embodiment, the frequency adjustment knob 11 of the microphone amplifier 1 is used.
And the frequency characteristic adjustment knob 12 are separately provided, and as shown in FIG.
The frequency and the frequency characteristic may be adjusted simultaneously, in which case the operation becomes easier. Also, it is needless to say that a digital switch having a similar function may be used instead of the knob.

Further, the configuration of the present device to which the microphone amplifier is applied is not limited to the one shown in FIG. 1, and for example, as shown in FIG. 6, an amplifier 21 and a speaker 22 are connected to the microphone amplifier 1 as sound reproducing means. The audio signal output from the microphone amplifier 1 may be amplified by the amplifier 21 and generated from the speaker 22. Further, as shown in FIG. 7, a plurality of monitors 4, 4 'may be provided, and LDP2 may be connected in parallel to these monitors. In this case, a video signal without captions is sent from the LDP 2 to one monitor 4 and a video signal with captions to be described by the performer is sent to the other monitor 4 ′. By placing it in the center and placing the other monitor 4 'on a small screen near the performer, it is possible to make the device suitable for business use.
