Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a singing acoustic device used when singing with a singing performance device such as a so-called karaoke device.

(Prior art) Traditionally, in restaurants, snack bars, etc., the playback signal of a singing accompaniment song recorded on a magnetic tape or disk, etc., and the singing audio signal input from a microphone are mixed and amplified by a main amplifier. A so-called karaoke device is used in which the music is played from a speaker. By the way, if the speaker of the karaoke device is located far from the singer or if the surrounding noise is large,
There have been problems such as it being difficult for the singer to hear the voice coming from the speakers and making it impossible to confirm whether the singer's singing voice matches the accompaniment. Furthermore, when the volume of the karaoke machine is increased so that the sound from the speakers can be heard accurately, there is a problem in that noise pollution occurs.

(Purpose of the invention) The present invention was made to solve the above-mentioned problems, and it is possible to accurately hear acoustics for singing such as accompaniment music and singing sounds without causing noise pollution. To provide an audio device for singing that allows the user to properly enjoy singing.

(Structure of the invention) The invention consists of a lyrics display section provided on a support stand, a pair of speakers installed on both left and right sides of the lyrics display section by support arms, and an audio signal input to the speakers. a support shaft that swingably supports the support arm, a first locking portion that locks the support arm in a forward use position, and a support arm that locks the support arm in a rear non-use position. In addition, the lyric display section is provided with a placement section for an ashtray, a pot, etc.

(Embodiment) FIG. 1 shows an embodiment of the singing audio device according to the present invention, and this singing audio device includes a support base 1, a lyrics display section 2 provided on the support base 1, and a lyrics display unit 2 provided on the support base 1. A pair of speakers 4 are provided on both left and right sides of the display section 2 by support arms 3. The support stand 1 includes a base 6 on which a moving caster 5 is provided, a support 7 made of a pair of square pipes erected on the base 6, and a reinforcing stay 8 that supports the support 7. A holding frame 10 for holding a video display 9 such as a television receiver is attached to the upper end of the pillar 7 so that the mounting angle can be adjusted using mounting bolts 11, thereby providing a lyric display section 2. It is being

Further, the support arm 3 of the speaker 4 is attached to the side surface of the support column 7 by a mounting tool 12, and
As shown by the solid line in the figure, the front surface of the support arm 3 contacts the locking pin 13 protruding from the support column 7 and is tilted forward, and the rear surface of the support arm 3 is held in the above-mentioned position as shown by the phantom line. The frame 10 is supported so as to be movable between a non-use position and an upright position in contact with a stopper 14 protruding from the rear side surface of the frame 10. That is,
As shown in FIG.
A tightening member 15 with a protruding portion a, and the support shaft 15
and a nut member 16 formed with a female threaded portion into which the tip threaded portion of a is screwed, and the support arm is rotated about the support shaft 15a by loosening the tightening member 15. It is becoming possible to do this. Then, with the support arm 3 set in the above-mentioned use position or non-use position, the tightening member 15 is
Alternatively, by rotating and tightening the nut member 16, the support arm 3 is clamped and fixed between the tightening member 15 and the nut member 16, and the support 7. In addition, a reinforcing spacer 1 is provided between the pair of square pipes constituting the pillar 7.
7 are arranged.

Further, a speaker 4 is attached to the upper end of the support arm 3 by a ball joint 18 so that the attachment angle can be adjusted freely (see FIG. 1). A stereo sound signal is input to the speaker 4 from a reception line 19 connected to a karaoke device (not shown), so that a singing accompaniment song and singing sound are played from the speaker 4, and the video display 9 receives an image signal from the receiving line 19, so that images such as lyrics and scenes are displayed on the video display 9.

Further, a support bracket 21 for supporting a singing microphone 20 is formed on the front surface of the holding frame 10 of the video display 9. The singing microphone 20 is connected to a karaoke apparatus via a transmission line 22. Further, as shown in FIG. 4, an auxiliary table 23 is formed in front of the holding frame 1, and through holes 24 and 25 are formed in this auxiliary table 23. And the above through hole 2
By attaching cushion rubbers 26 and 27 to 4 and 25, a place for placing an ashtray A, a cup B, etc. is formed.

In this way, the speakers 4 supported by the support arms 3 are placed on both left and right sides of the lyrics display section 2 consisting of the video display 9 provided on the support stand 1.
, the singer can watch the lyrics displayed on the video display 9 and sing while listening to the accompaniment music played from the speaker 4 and the stereo sound of his/her own singing voice. Therefore, the stage etc. where the singer is located,
To enjoy a karaoke performance without increasing the volume of the karaoke device even when the speaker of the karaoke device is located at a remote location.

In addition, as described above, the support arm 3 of the speaker 4
a first locking portion consisting of a locking pin 13 that rotatably supports the support arm 3 by the support shaft 15a of the fixture 12 and locks the support arm 3 in a forwardly inclined use position; Since the speaker 4 is provided with a second locking part consisting of a stopper 14 that locks the speaker 3 in a rearwardly inclined position when not in use, the speaker 4 can be installed at a position where the singer can easily hear the sound when in use, By positioning the speaker 4 above the video display 9 during use, there is an advantage that the storage space can be reduced. Note that the installation height of the speaker 4 may be adjusted as necessary by, for example, forming the support arm 3 that supports the speaker 4 with a plurality of pipe members that are slidably connected. Alternatively, the support arm 3 may be attached to the holding frame 10 of the video display 9.

Further, in the above embodiment, a pair of speakers 4 are arranged on the left and right sides of the lyrics display section 2, so that stereo sound can be played.
In addition to this configuration, a speaker may be disposed below or on the side of the holding frame 10 to generate so-called 4-channel sound to obtain a more realistic sound effect. In addition, the above-mentioned components include an amplifier that amplifies the acoustic signal output from the karaoke device (not shown), a volume control that adjusts the volume flowing from the speakers 4, a tone control that adjusts the sound range, and a balancer that adjusts the balance of the volume of each speaker 4. The structure may be provided on the front surface of the frame 10 or the like.

Further, in the above embodiment, the lyrics display section 2 is provided with a video display 9, but the lyrics display section can be constructed by forming a music stand on which lyrics cards or musical scores are installed in place of the video display 9. You can.

Further, a recording device such as a tape recorder may be installed in the holding frame 10 of the lyrics display section 2, and the configuration may be such that the singer's singing voice and an accompanist can be recorded as necessary. A money insertion machine may be provided and the singing sound may be recorded when the singer or the like inserts money.

(Effects of the invention) As explained above, the present invention is configured such that a pair of speakers supported by support arms are disposed on both the left and right sides of the lyrics display section, and acoustic signals are input to the speakers. Therefore, even when a singer is located away from the speakers of the karaoke device, there is an advantage that the singer can enjoy the karaoke performance while listening to the accompaniment music etc. played from the speakers without causing noise pollution.
