Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke performance device capable of singing while feeling the rhythm of karaoke accompaniment music.

[0002]

2. Description of the Related Art In recent years, karaoke-related products have become widespread, and there are increasing opportunities to easily enjoy karaoke performance not only at snacks and homes but also at karaoke boxes and the like. In the karaoke performance, a large and expensive speaker system must be installed in order to enhance the bass reproduction capability and enjoy a realistic performance. Also, it is difficult for an amateur to match his singing voice by riding the rhythm of accompaniment music,
In a karaoke performance including a video screen such as a laser disc, a method of keeping up with the rhythm of the accompaniment is performed by changing the color display of the lyrics displayed on the screen.

[0003]

When an amateur tries to sing karaoke accompaniment music in the background, he or she tends to miss the tempo of the accompaniment, which makes it difficult to sing along with the rhythm. In addition, a large speaker system needs to be installed in order to reproduce a rich bass sound, and there is a drawback that it is difficult to secure the space in a small room. The present invention has been made to compensate for the above-mentioned conventional drawbacks, and an object of the present invention is to enjoy karaoke performance in a stage mood while feeling the rhythm of accompaniment music not only by hearing and sight but also by the body. An object of the present invention is to provide a device capable of obtaining a sufficient bass feeling even in a small room without using a large speaker.

[0004]

Therefore, according to the present invention,
A signal obtained by adding the accompaniment signal of the karaoke source and the singing voice signal of the microphone input is reproduced from a small loudspeaker in the hall, and a bass signal extracted from the accompaniment music by a built-in bass speaker or vibrating unit in a stage-shaped cabinet. Driven by, the heavy low-pitched sound is reproduced while applying plate vibration to the stage floor surface.

[0005]

[Function] A cabinet with a large internal volume is required to reproduce heavy bass, but by making it a stage shape, the indoor space can be effectively utilized and a sufficient singing space can be secured. . Also, from this stage structure heavy bass reproduction cabinet, the powerful deep bass of the accompaniment sound is reproduced, and the low frequency rhythm sound such as the drum bass of the accompaniment music is transmitted from the feet to the singer as a sensation through the floor vibration. . This stage type speaker
Since the system is responsible for the low frequency band, it is sufficient for the loudspeaker for in-field loudspeaking to handle only the middle and high frequency bands, so a small volume and lightweight speaker such as a wall-mounted type is sufficient, and a narrow indoor space It can be used effectively.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A karaoke playing device according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a speaker layout diagram and circuit configuration diagram showing an embodiment of a karaoke playing device according to the present invention. A musical tone signal from a device group 1 for reproducing a karaoke source recorded on a music tape, a compact disc, a laser disc or the like is branched via an amplifier 2 and an attenuator 3, and one of them is added to an adding circuit 9,
The other is added to the low pass filter 12.

A voice signal obtained by picking up a singing voice by a singer 16 in a karaoke room 15 by a microphone 4 is branched via an amplifier 5 and an attenuator 6, one of which is added to an adding circuit 9 and the other of which is called a reverberation processing circuit 7. Attenuator 8
Add an appropriate level of reverberation and add it to the adder circuit 9.

The output signal of the adder circuit 9 in which reverberation is added to the karaoke accompaniment music and the echoed singing voice signal is mixed is level-adjusted and amplified by the attenuator 10 and the output amplifier 11 and added to the loudspeakers 17 and 18 for loudness. The sound is radiated into the room 15.

On the other hand, the heavy bass signal from the low-pass filter 12 extracted from the karaoke accompaniment signal is applied to the attenuator 13.
By driving the built-in bass speaker in the stage-type speaker system 19 via the output amplifier 14 and the output amplifier 14, the floor surface 19a is vibrated and the acoustic port 19 is operated.
Heavy bass is radiated from the b and 19c into the room 15.

FIG. 2 is a sectional view showing the internal structure of the stage type speaker system 19 shown in FIG. The karaoke accompaniment signal is passed through the low-pass filter 12 and a low-frequency signal of less than one hundred and several tens hertz is added to the bass speaker unit 20. Direct sound from the diaphragm of speaker unit 20 and its back pressure are acoustic mazes 2 with a special structure by partition plate 21.
The bass component that has been enhanced by passing through 2 is combined, and the bass components are radiated into the room as heavy bass from the acoustic ports 19b and 19c.

Further, the partition plate 21 plays a role of supporting and reinforcing the stage floor surface 19a, and the acoustic maze 22 also plays a role of giving deep bass vibration to the stage floor surface 19a by passing low frequency sound waves. The low-frequency component during karaoke performance is reproduced from the stage-type speaker system 19 which also serves as a stage and which has a large internal volume and is reinforced with low-pitched sound.

[0012] Therefore, for loudspeaking in the hall, it is sufficient to be able to reproduce only the middle and high frequencies.
It suffices if the lightweight loudspeakers 17 and 18 are provided, and the space in the room can be effectively utilized. Moreover, since the low-frequency component of the rhythm section such as the drum bass is transmitted to the singer as a sensory vibration through the stage floor surface 19a, it is possible to sing while feeling the rhythm, it is easy to get on the accompaniment tempo, and even an amateur can easily sing. There are advantages.

[0013]

As described above, according to the present invention, the heavy bass sound of the rhythm section is generated from the floor of the stage, so that it is possible to provide a karaoke apparatus in which the tempo is easy to ride.
