Description

本発明はイヤホン、詳しく言えばサラウンド効果を有するマルチチャンネルイヤホンに関するものである。 The present invention relates to an earphone, and more particularly to a multi-channel earphone having a surround effect.

周知のイヤホン１０は図１に示すようにハウジング１１内に平行に配列される前方拡声器１２、中間拡声器１３、及び後方拡声器１４を有し、前方拡声器１２及び後方拡声器１４によりサラウンドの前後音場効果を別々に模擬する。図２に示すようにもう一つの周知のマルチチャンネルイヤホン２０はハウジング２１内に前方拡声器２２、中間拡声器２３、及び後方拡声器２４を有する。その特徴は前方拡声器２２及び後方拡声器２４の音放射面が別々に外向きに配置され、中軸線と中間拡声器２３の軸線との間に角を有することである。第一種または第二種の周知のイヤホン１０、２０などのいずれも前後拡声器の音波伝送方向は実際上のサラウンドの音波伝送方向とやや異なる。実際上のサラウンドにおいて前方音響効果の音源は使用者の前方に位置付けられるため音波は使用者の前方に向かって進み、後方音響効果の音源は使用者の後方に位置付けられるため音波は使用者の後方に向かって進む。従って最良なサラウンドは図３に示すように前方音響効果が使用者の前方の５０度から７０度の間であり、後方音響効果が後方の５０度から７０度の間であり、左右両側が左右音響効果の範囲である。周知のマルチチャンネルイヤホンの前後拡声器の配置方法において音波の伝送方向が考慮されなかったため、模擬サラウンド効果の面では欠点がある。 As shown in FIG. 1, the known earphone 10 includes a front loudspeaker 12, an intermediate loudspeaker 13, and a rear loudspeaker 14 that are arranged in parallel in a housing 11, and surrounds by the front loudspeaker 12 and the rear loudspeaker 14. Simulate front and rear sound field effects separately. As shown in FIG. 2, another known multi-channel earphone 20 has a front loudspeaker 22, an intermediate loudspeaker 23, and a rear loudspeaker 24 in a housing 21. The feature is that the sound emitting surfaces of the front loudspeaker 22 and the rear loudspeaker 24 are separately arranged outward and have an angle between the middle axis and the middle loudspeaker 23. The sound transmission direction of the front and rear loudspeakers is slightly different from the actual sound transmission direction of surround in any of the first type or second type of well-known earphones 10 and 20. In the actual surround, the sound source of the front acoustic effect is positioned in front of the user, so that the sound wave advances toward the front of the user, and the sound source of the rear sound effect is positioned in the rear of the user, so that the sound wave is behind the user. Proceed toward. Therefore, as shown in FIG. 3, the best surround is that the front sound effect is between 50 degrees and 70 degrees in front of the user, the rear sound effect is between 50 degrees and 70 degrees in the rear, and the left and right sides are left and right. The range of the sound effect. Since the sound wave transmission direction is not considered in the known arrangement method of the front and rear loudspeakers of multi-channel earphones, there is a drawback in terms of the simulated surround effect.

本発明の主な目的は臨場感のあるサラウンドをよりいっそう模擬可能であるマルチチャンネルイヤホンを提供することである。 A main object of the present invention is to provide a multi-channel earphone that can further simulate realistic surround.

上述の目的を達成するため本発明によるマルチチャンネルイヤホンは二つの使用者の両耳に装着されるイヤホンユニットを備える。イヤホンユニットは耳を完全に被覆可能なハウジングと、耳の位置に対応するようにハウジングの中間部に装着される中間拡声器と、耳の前方に対応するようにハウジング内に装着される前方拡声器と、耳の後方に対応するようにハウジング内に装着される後方拡声器と、ハウジングの中間部に装着される重低音拡声器とを備える。その特徴は前方拡声器の音放射面が耳の輪郭の正面、後方拡声器の音放射面が耳の輪郭の背面に向かうことである。これにより前後拡声器から耳に伝送された音波を臨場感のあるサラウンドの音波によりいっそう近づけ、迫真的な音響効果を得ることが可能である。 In order to achieve the above object, a multi-channel earphone according to the present invention includes an earphone unit that is worn on both ears of two users. The earphone unit has a housing that can completely cover the ear, an intermediate loudspeaker that is attached to the middle part of the housing so as to correspond to the position of the ear, and a front loudspeaker that is attached in the housing so as to correspond to the front of the ear. A rear loudspeaker mounted in the housing so as to correspond to the rear of the ear, and a heavy bass loudspeaker mounted in the middle part of the housing. The feature is that the sound emitting surface of the front loudspeaker faces the front of the contour of the ear, and the sound emitting surface of the rear loudspeaker faces the back of the contour of the ear. As a result, the sound waves transmitted from the front and rear loudspeakers to the ear can be brought closer to the realistic surround sound waves, and a realistic sound effect can be obtained.

以下、本発明の一実施例について図面に基づいて説明する。まず図面の説明は次の通りである。
図４は本発明の一実施例の構造を示す模式図である。
図５は図４の５‐５線に沿う断面構造を示す模式図である。
本発明によるマルチチャンネルイヤホンは二つの使用者の両耳に装着されるイヤホンユニットを含む。イヤホンユニット３０は図４及び図５に示すように下記のものを含む。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. First, the description of the drawings is as follows.
FIG. 4 is a schematic diagram showing the structure of an embodiment of the present invention.
FIG. 5 is a schematic diagram showing a cross-sectional structure taken along line 5-5 of FIG.
The multi-channel earphone according to the present invention includes an earphone unit worn on both ears of two users. The earphone unit 30 includes the following as shown in FIGS.

ハウジング３１は耳を完全に被覆し、音隔離効果を形成することが可能である。
中間拡声器３２は耳の位置に対応するようにハウジングの中間部に装着される。
前方拡声器３３は耳の前方に対応するようにハウジング内に装着され、その音放射面３３１が耳の輪郭４０の正面４１に向かい、かつ音放射面３３１の中軸線３３２と人体の鼻を貫き頭部を左右両辺に分割する模擬鉛直線５０との間の角度閘１が３５度以下である。 The housing 31 completely covers the ear and can create a sound isolation effect.
The intermediate loudspeaker 32 is attached to the middle part of the housing so as to correspond to the position of the ear.
The front loudspeaker 33 is mounted in the housing so as to correspond to the front of the ear, and its sound emitting surface 331 faces the front surface 41 of the ear outline 40 and penetrates the central axis 332 of the sound emitting surface 331 and the human nose. The angle 閘 1 between the simulated vertical line 50 dividing the head into left and right sides is 35 degrees or less.

後方拡声器３４は耳の後方に対応するようにハウジング内に装着され、その音放射面３４１が耳の輪郭４０の背面４２に向かい、かつ音放射面３４１の中軸線３４２と前記鉛直線５０との間の角度閘２が３５度以下である。
重低音拡声器３５は中間拡声器３３の下方に位置するようにハウジング内に装着される。
本実施例は前後方拡声器の配置角度を変えることにより放射された音波の伝送径路を臨場のサラウンド音場に近づけ、迫真的な音響効果を得る。 The rear loudspeaker 34 is mounted in the housing so as to correspond to the rear of the ear, and its sound emitting surface 341 faces the back surface 42 of the contour 40 of the ear, and the central axis 342 of the sound emitting surface 341 and the vertical line 50 The angle 閘 2 between is 35 degrees or less.
The heavy bass loudspeaker 35 is mounted in the housing so as to be positioned below the intermediate loudspeaker 33.
In the present embodiment, by changing the arrangement angle of the front and rear loudspeakers, the transmission path of the radiated sound wave is brought close to the actual surround sound field, and a realistic acoustic effect is obtained.

またハウジング内に振動器３６を配置することが可能である。特に中間拡声器３２の後方に配置し、重低音拡声器３５と組み合わせればイヤホンに振動効果を生成させることが可能である。例えば重低音周波数が１２０Ｈｚ以下であれば振動波が生じる。また同時に重低音の出力音量が所定の値に達すれば振動波が生じるように設定することも可能である。本実施例によるイヤホンは低音を聞く場合、静止状態を保持し、音量が設定値以上、重低音周波数が所定の周波数以下である場合、音の出力に伴い振動効果を生成し、よりいっそう良好な臨場感を達成することが可能である。
本実施例は前後方拡声器の配置角度のみを変えるものであるが、音源を正確にする効果を得ることが可能であるため、視聴者に良好な定位感を与えることが可能となる。また本実施例によるイヤホンは前述の振動器を配置するとこにより視聴者が極上の音響を享受することを可能にする。 It is also possible to arrange a vibrator 36 in the housing. In particular, if it is arranged behind the intermediate loudspeaker 32 and combined with the deep bass loudspeaker 35, the earphone can generate a vibration effect. For example, if the heavy bass frequency is 120 Hz or less, a vibration wave is generated. At the same time, it is possible to set so that a vibration wave is generated when the output volume of the heavy bass reaches a predetermined value. The earphone according to the present embodiment maintains a stationary state when listening to a bass, generates a vibration effect with the output of sound when the volume is equal to or higher than a set value and the heavy bass frequency is equal to or lower than a predetermined frequency, and is even better. It is possible to achieve a sense of reality.
In the present embodiment, only the arrangement angle of the front and rear loudspeakers is changed, but since an effect of making the sound source accurate can be obtained, it is possible to give the viewer a good sense of localization. In addition, the earphone according to the present embodiment enables the viewer to enjoy the finest sound by arranging the above-described vibrator.
