Abstract

PURPOSE:To reduce an ambient noise by providing a speaker at the head part of a player, an adder between the loudspeaker and a sound means for constituting a game device, and a microphone interposed the adder with an opposite phase converter. CONSTITUTION:A pair of left and right speakers 5, 6 are connected to a sound means 20 of a game device 1 by interposing adders 11, 12, microphones 7, 8 are connected to the adders 11, 12 by interposing opposite phase converters 13, 14, and an electric signal of a sound from the microphone 7, 8 is set as an electric signal of opposite phase and outputted to the adders 11, 12. Accordingly, a noise surrounding the head part 9 of a player who sits down on a chair 4 and operates a game 1 is taken into the microphones 7, 8, and the noise of opposite phase against the noise is applied, therefore, an ambient noise is cancelled for the player, and the sound space as for as a game sound by the sound means 20 can be realized.

【実施例】以下に本発明を、その実施例について、添付の図面を参照して説明する。 The present invention EXAMPLES Hereinafter, the embodiment will be described with reference to the accompanying drawings. 図1は、本発明による一実施例の使用状態を示す斜視図であり、図2は、同上実施例の要部を示すブロック図である。 Figure 1 is a perspective view showing a use state of an embodiment according to the present invention, FIG. 2 is a block diagram showing an essential part of the same embodiment. 図1の1は全体が略家形のゲ−ム装置で、このゲ−ム装置1の上半分である屋根形部のほぼ全体には、CRTなどの表示部(図示省略)があり、表示部の下方には、操作板部3が突出して形成されている。 Whole 1 in figure 1 is substantially house shape gate - in beam device, the gate - to substantially the entire roof-shaped part is a half of the beam device 1 is a display unit such as CRT (not shown), a display below the section, the operation plate 3 is formed to project. 4はプレ−ヤ用の椅子で、ゲ−ム装置1に連成して形成されるか、あるいは、ゲ−ム装置1に接続可能に形成されている。 4 pre - chair for Ya, gate - either formed form with the beam device 1, or gate - is connectable to forming the beam device 1. 5、6は、左右一対のスピ−カで、椅子4の頂部の左右に、それぞれ配設されている。 5 and 6, a pair of left and right spin - in mosquitoes, the left and right of the top of the chair 4, are disposed, respectively. 7、8は、左右一対のマイクロフォンで、椅子4の頂部の左右のサイド壁に、それぞれ配設されている。 7 and 8, the left and right pair of microphones, the left and right side walls of the top portion of the chair 4, are disposed, respectively.

【0007】左右一対のスピ−カ5、6は、図2に示されるように、それぞれが、加算器11、12を介在して、ゲ−ム装置1の内部にあるサウンド手段20に、たとえば、床下配線などによって接続されている。 [0007] pair of spin - mosquito 5,6, as shown in FIG. 2, respectively, interposed adders 11 and 12, gate - the sound unit 20 in the interior of the beam device 1, e.g. It is connected, such as by underfloor wiring. 左側のマイクロフォン7は、逆位相変換器13を介在して、加算器11に接続され、右側のマイクロフォン8は、逆位相変換器14を介在して、加算器12に接続されている。 Left microphone 7 is interposed an anti-phase converter 13, is connected to the adder 11, the right side of the microphone 8 is interposed an inverse phase converter 14 is connected to the adder 12. 左右の逆位相変換器13、14は、左右のマイクロフォン7、8からくる音の電気信号を、逆の位相の電気信号にして、左右の加算器11、12に出力する。 Left and right inverse phase converter 13 and 14, an electrical signal of the sound coming from the left and right microphones 7,8, and the electrical signals of opposite phases, and outputs to the left and right adders 11 and 12.

【0008】上述のごとくなる本実施例は、椅子4に座って、ゲ−ム装置1を操作するプレ−ヤを取り巻く騒音、すなわち、プレ−ヤの頭部9を取り巻く騒音が、左右のマイクロフォン7、8にて取り込まれ、ゲ−ム装置1のサウンド手段20からのゲ−ム用のサウンドが、左右のスピ−カ5、6から再生されるときに、この騒音とは逆の位相の騒音が加えられるようになるため、結果として、ゲ−ム装置1を操作するプレ−ヤ自身にとり、周囲の騒音が打ち消された、本来のゲ−ム用サウンドのみの音空間が、実現できることになる。 [0008] The present embodiment composed as described above is seated in a chair 4, gate - Pre manipulating beam device 1 - noise surrounding Ya, i.e., pre - noise surrounding Ya head 9, the left and right microphone taken at 7,8, gate - gate from the sound unit 20 of the beam device 1 - sound for beam is, the left and right spin - when reproduced from mosquito 5,6, of opposite phase from this noise since so noise is added, as a result, gate - pre manipulating beam device 1 - taken up in ya itself, it countered the ambient noise, the original gate - that sound space only sound for beam can be realized Become.

【0009】言い換えると、プレ−ヤの頭部まわりの騒音を直接的に取り込んで、その騒音とは逆の位相の騒音を、リアル・タイムにつくって、騒音を打ち消し、そのゲ−ム用サウンドのみに没頭できるようになる。 [0009] In other words, the pre - capture directly the noise around ya head, the noise of the opposite phase of its noise, made in real-time, cancel the noise, the gate - sound for a continuously only it will be able to immerse yourself in. なお、 It should be noted that,
スピ−カ5、6、ならびにマイクロフォン7、8、逆位相変換器13、14、加算器11、12は、それぞれ、 Spin - Ca 5,6, and microphones 7,8, inverse phase converter 13, an adder 11 and 12, respectively,
左右一対として説明してきたが、これらは、左側のみ、 Has been described as a pair, they are left alone,
あるいは右側のみのように、ひと組みであっても良いことは、勿論である。 Or as in the right-hand side only, it may be a person set is, as a matter of course. また、立体音響用のために、多数のスピ−カを備えるゲ−ム装置の場合は、それぞれのスピ−カごとに、マイクロフォン、逆位相変換器、加算器を配設しても良いことは、勿論である。 In order for the stereophonic, multiple spin - For beam apparatus, each of the spin - - gate with mosquitoes every month, microphone, inverse phase converter, it may be arranged adder , as a matter of course.

【0010】 [0010]

【効果】以上のようになる本発明は、プレ−しているゲ−ム装置の周囲の騒音を、言い換えると、プレ−ヤの頭部まわりのノイズを軽減できるため、プレ−ヤ自身にとっては、今まで以上に音の臨場感が得られる効果があると共に、騒音そのものに対して、アクティブなコントロ−ルができるため、多数のゲ−ム装置の設置条件や、立地条件の制限が無くなるという効果がある。 EFFECT above to become present invention, pre - to have gate - noise around the arm device, in other words, pre - because it can reduce the noise around ya head, pre - for Ya itself , together with the effect of the realism of sound than ever obtained for noise itself, active control - since it is Le, a number of gate - installation conditions and the beam device, that of location restrictions are eliminated effective. とくに、大形ゲ−ム装置の場合などで、3Dサウンド、いわゆる立体音像を考慮する必要がある場合には、音の臨場感が得られるという点で、極めて大きな利点がある。 In particular, large gate - in a case of a beam device, 3D sound, when it is necessary to consider the so-called three-dimensional sound image, in that realism of the sound is obtained, there is a very great advantage.
