DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke apparatus which enables a singer to sing while simultaneously listening to his / her own singing voice and a singing voice mixed with karaoke accompaniment music.

[0002]

2. Description of the Related Art In recent years, karaoke apparatuses have become widespread, and the number of opportunities to easily enjoy snacks, homes, karaoke boxes, and the like has increased. FIG. 4 is a basic functional block diagram of a general karaoke apparatus of this type.

In FIG. 1, reference numeral 1 denotes a microphone for converting the singing voice of a singer on the stage into an electric signal. The output signal of the microphone is input to a preamplifier 2 having various control functions, and the sound quality and reverberation are appropriately processed. Later, adding means 4
Is mixed with the karaoke accompaniment music signal generated from the music generator 3. The mixed signal is appropriately amplified by a power amplifier 4 and reproduced and output by a speaker 6 for a customer seat and a speaker 7 for a stage.

FIG. 5 is a plan view showing an example of a relative positional relationship between a stage, a customer seat, and a speaker. The speaker 6 for the audience seat is arranged so as to emit a playback sound mainly toward the audience seat 8, and the speaker 7 for the stage is arranged so as to emit the playback sound toward the singer 10 of the stage 9.

[0005]

[0005] By the way, in terms of ease of listening at the audience seats, a sound in which an effect sound such as an echo is slightly emphasized is preferred, but, on the other hand, a singer sings with a rebound of his own voice. Since it becomes a factor of easiness, it is better to satisfy the following conditions. The ratio of the fundamental wave component from the microphone (the fundamental wave component in the present invention refers to the raw voice of the singer who has not been subjected to reverberation processing) is preferably large. Conversely, it is better that the components of sound effects such as echoes are lower. A low sound component (sound having a low frequency) is not required among the fundamental wave components. This reduces costs from the point of view of circuit design.

In the conventional karaoke apparatus, there is a problem that the ease of listening at the audience seat and the ease of singing the singer cannot be compatible.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problem, and to separate a microphone signal into two systems so that sound quality can be individually controlled, thereby making it easier to listen to the audience and sing for the singer. An object of the present invention is to realize a karaoke device that can be operated.

[0008]

According to the first aspect of the present invention, a singer's voice signal input through a microphone is appropriately processed and then added to a karaoke accompaniment signal. First reproducing means for reproducing the singer on the audience seat and the stage, and second reproducing means for obtaining a reproduced output signal by separately processing the voice signal of the singer of the microphone input and reproducing the reproduced signal toward the singer. It is characterized by having.

With such a configuration, the microphone input signal is divided into two systems, and independent sound quality control is performed for each, so that the singer can simultaneously hear the sounds from the two systems. This allows the singer to sing in situations that are very easy to sing.

In this case, for example, the first
A preamplifier for performing processing for emphasizing an effect sound such as an echo on an audio signal, an adding means for adding the output of the preamplifier to a karaoke accompaniment signal, and appropriately amplifying an output signal of the adding means. The second reproducing means is composed of a speaker for a seat and a means for reproducing from a speaker for a stage, and a second reproducing means for extracting a fundamental wave component of a singer from an audio signal, and appropriately amplifying an output of the preamplifier. And means for reproducing from a stage speaker.

According to the third aspect of the present invention, there is provided a first reproducing means for appropriately processing a voice signal of a singer input through a microphone, adding the signal to a karaoke accompaniment signal, and reproducing the added signal toward a customer seat and a stage. Means for obtaining a reproduction output signal of the singer's voice signal input through the microphone by a separate process and adding this to the addition signal.

According to such a configuration, the microphone input signal is divided into two systems and processed, but only one system is required for reproducing to the audience and the singer, and the configuration of the apparatus is different from that of the first embodiment. Easy and cheap.

In this case, for example, the first
A preamplifier for performing processing for emphasizing sound effects such as echoes on an audio signal, an adding means for adding the output of the preamplifier and the karaoke accompaniment signal, and appropriately amplifying an output signal of the adding means. The second reproducing means may be constituted by a speaker for the customer seat and a means for reproducing from the speaker for the stage, and the second reproducing means may be constituted by a preamplifier for performing a process of extracting a fundamental wave component of the singer from the audio signal.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. FIG. 1 is a principle configuration diagram of a karaoke apparatus according to the present invention. In FIG. 1, the same parts as those in FIG. 4 are denoted by the same reference numerals, and description thereof will be omitted.

According to the present invention, a microphone signal is divided into two systems so that sound quality can be controlled independently of each other. That is, the second preamplifier 1 is added to the configuration of FIG.
1, a second power amplifier 12 and a second stage speaker 13 are added to control a microphone signal in two systems.

The second preamplifier 11 is connected to the microphone 1
And performs appropriate processing on the audio signal from the external device. The second power amplifier 12 appropriately amplifies the audio signal and reproduces the audio signal via the second stage speaker 13.

The second stage speaker 13 is installed in the vicinity of the singer 10 and directed toward the singer, as shown in the layout diagram of FIG. 2, and is arranged so that its output sound can be heard substantially only by the singer 10.

In such a configuration, the singer listens to the synthesized sound of the singing voice emphasized by an effect sound such as an echo and the karaoke accompaniment music through the speaker 7 and simultaneously listens to his / her own live singing voice through the speaker 13. be able to.

According to an experiment, when singing while listening to the sound of both the stage speaker 7 and the second stage speaker 13, the result is that the sound is extremely good and the singing is extremely easy. The singer who stands on the stage is so illusion that he is the best.

In the case of a professional singer's performance in a theater, the emphasis is on the audience, while in the case of karaoke, the singer is more important than the audience at the audience. The device of the present invention is a device that emphasizes singers and is a device that can provide a reasonable result of preferential treatment of investors.

It should be noted that the foregoing description has been directed to specific preferred embodiments for the purpose of illustration and illustration of the invention. Therefore, the present invention is not limited to the above-described embodiments, and includes many more modifications without departing from the spirit thereof.
This includes deformation.

For example, as shown in FIG. 3, the second power amplifier 12 in FIG.
Is input to the adding means 4, the karaoke accompaniment music and the output of the first preamplifier 2 are combined and amplified by the power amplifier 5.

According to such a configuration, the raw singing voice of the singer 10 flows to both the stage 9 and the audience seat 8. Also in this case, the singer has the same operation and effect as the embodiment of FIG. At the audience seats, the singing voice is mixed, so it is undeniable that it is a little difficult to hear, but karaoke is not so problematic because singers are emphasized as described above.

The preamplifier 11 can be adjusted so that the singer himself can adjust the high / low sound passage characteristics and other characteristics of the preamplifier 11 at hand immediately before or during singing. it can.

Further, in place of the stage speaker 13, for example, a headphone or an earphone for one ear can be used. In such a case, the live singing voice does not reach the audience at all, and the intended sound can be played to the singer and the audience. Note that the number of the speaker 6 for the customer seat is not limited to one, and a plurality of speakers 6 can be installed in any direction as needed.

The appropriate processing in the second preamplifier 11 is, for example, cutting of low-frequency components, echo processing weaker than that of the first preamplifier 2, and the like.

[0027]

As described above, according to the present invention, the following effects can be obtained. According to the first aspect of the present invention, the microphone input signal is divided into two systems, and independent sound quality control is performed for each, so that the singer can simultaneously hear sounds from the two systems.

Thus, the following problems can be solved at once. (1) The melody is difficult to hear (2) There is no rebound of my voice (3) The clarity of the voice is low (4) The overall sound is not powerful (5) The echo is not appropriate (6) Around the audience It is difficult to sing if it is loud (7) Howling is likely to occur

[0029] According to the third aspect of the present invention, the first aspect is provided.
The same effect as that of the first aspect of the present invention is exhibited, and at the same time, only one power amplifier is required, so that a karaoke apparatus which is simpler and less expensive than the karaoke apparatus of the first aspect can be realized.

Since the low-frequency component may be cut by the second reproducing means, an inexpensive amplifier circuit can be used for the power amplifier 12, and the price of the karaoke apparatus as a whole can be reduced. The effect is great.
