Abstract

PURPOSE:To improve the gate effect by outputting a game sound of the handy game machine from left and right speakers in a stereo signal and outputting the stereo game sound with a spread to the left and the right. CONSTITUTION:A left side speaker 3 and a right side speaker 4 of a stereo equipment are mounted so as to be deviated horizontally at a small angle with respect to parallel axial lines CLL, CLR to a center line C of a case CA. As a result, since the stereo game sound outputted from the left speaker 3 and the right speaker 4 has a spread to the left and right, the game effect is improved.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention, when inserted into the main body of a handy game machine, receives a stereo signal output from the handy game machine and connects the left speaker and the right speaker.
This invention relates to a stereo device for a handheld game machine for enjoying game sound coming from a player in stereo.

[Problem to be Solved by the Invention] However, some people find it very bothersome to put earphones in their ears and listen to game sounds while playing games on a handheld game machine. It is desirable for players to output game sound directly from the speakers. On the other hand, speed
Outputting game sound from a handheld game machine may cause a nuisance to others, so it is problematic to permanently attach speakers to all handheld game machines, as it may lead to high costs. There is. Furthermore, installing two left and right speakers on a handheld game machine, which is generally made small, poses a space problem.

Therefore, in the present invention, when installed in the main body of a handy game machine, a stereo signal of game sound is input from the handy game machine, and stereo game sound is output from the left and right speakers. At the same time, by mounting the left and right speakers so that their directions are deflected by a small angle to the left and right, the game can be improved.
The technical problem to be solved is to improve the stereo effect of music sound.

[0005]

[Means for Solving the Problems] The technical means for solving the above problems is to attach a stereo device of a handy game machine to a case that is inserted into the main body of the handy game machine. a stereo signal input plug inserted into the stereo signal output jack, and a game output from the handy game machine via the stereo signal input plug.
an amplifier circuit that amplifies a stereo signal of a stereo sound to stereo output power, and a left speaker and a right speaker that output audio in response to the stereo output power output from the amplifier circuit, and The left speaker and the right speaker are attached to the case while being deflected by a small angle to the left and right, respectively.

[0006]

[Operation] According to the stereo device for a handy game machine having the above configuration, when the case is inserted into the main body of the handy game machine, the stereo signal input plug attached to the case is attached to the main body. into the stereo signal output jack. In this state, the stereo signal of the game sound output from the handy game machine is input to the amplifier circuit via the stereo signal output jack and the stereo signal input plug. When the amplifier circuit receives a stereo signal,
The stereo signal is amplified to stereo output power and output. The stereo output power is supplied to the left speaker and the right speaker, and stereo game sound is output from the left speaker and the right speaker. At this time, since the left speaker and the right speaker are deflected by small angles to the left and right, respectively, the game sound is output with a spread to the left and right, thereby enhancing the stereo effect.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view of the stereo device 1 of this embodiment inserted into a handy game machine HG. The panel surface of the handy game machine HG is provided with an LCD display for displaying game images, operation keys, and the like. Furthermore, a stereo signal output jack is attached to the bottom of the handy game machine HG so that a stereo signal corresponding to the game sound of each game can be output. When the stereo device 1 is inserted into the handy game machine HG as shown in FIG. 1, a stereo signal input plug 2, which will be described later, attached to the stereo device 1 is inserted into the stereo signal output jack. In addition, the stereo device 1
A left speaker 3 and a right speaker 4 are attached to the speaker.

FIG. 2 is a block diagram showing the electronic circuit of the stereo device 1. As shown in FIG. As shown in FIG. 2, the stereo signal output circuit L-ch provided in the handy game machine HG
The left and right stereo signals outputted from the and R-channels are input from the stereo signal output jack J to the left channel power amplification circuit 5 and the right channel power amplification circuit 6 via the stereo signal input plug 2. The left channel power amplification circuit 5 and the right channel power amplification circuit 6 power amplify the left and right stereo signals, respectively, and output the respective amplified powers to the left speaker 3 and the right speaker 4. The left speaker 3 and the right speaker 4 output stereo game sounds corresponding to the respective games when supplied with respective amplified power.

FIG. 3 is a front view of the stereo device 1, FIG. 4 is a plan view thereof, and FIG. 5 is a right side view thereof. The case CA of the stereo device 1 is made of plastic, and a grid 7 is formed in the portion where the left speaker 3 and right speaker 4 are attached. Further, an insertion guide 8 is formed in the upper part of the case CA, and the insertion guide 8 is removably connected to the lower part of the handy game machine HG. In addition,
The left channel power amplifying circuit 5 and the right channel power amplifying circuit 6 are built in the rear of the left speaker 3 and right speaker 4 arrangement portion of the SC. As shown in FIG. 4, the stereo signal input plug 2 is protruded upward from the center of the upper surface of the case CA, and when the stereo device 1 is inserted into the handy game machine HG, the stereo signal input plug 2 is inserted into the handheld game machine HG. An input plug 2 is inserted into a stereo signal output jack J. Figure 6 shows the left speaker for case CA.
FIG. 3 is a sectional view showing how the speaker 3 and the right speaker 4 are attached. As shown in the figure, the left speaker 3 and the right speaker 4 are connected to virtual axes CLL and C which are parallel to the central axis C of the case CA.
They are attached in a state where they are deflected by α degrees, for example, 1.5 degrees, to the left and right, respectively, with respect to LR. Therefore, from left speaker 3 and right speaker 4, each game
When the stereo game sound corresponding to the game is output,
Stereo game sound is output with a spread in the left and right directions, improving the stereo effect in the game.

0010

As described above, according to the present invention, the left speaker and the right speaker, which output the stereo signal of the game sound from the handheld game machine, can be adjusted slightly in the left and right directions, respectively. Since it is attached to the case with an angular deflection, the stereo game sound is outputted with a spread in the left and right directions, which has the effect of improving the stereo effect in the game.
