Description

本発明は、骨伝導式のスピーカ及びこれを用いた眼鏡に関する。   The present invention relates to a bone conduction type speaker and spectacles using the same.

従来、頭部の骨、例えば頭骸骨等に機械的な振動を加えることによって音を伝えるようにした、いわゆる骨伝導式のスピーカが広く知られている。このような骨伝導スピーカＳＰは、例えば、図８（Ａ）に示されるヘッドセットＨＳのように、ヘッドバンド１の両端に取り付けられたり、又、図８（Ｂ）に示される眼鏡ＧＳのように、つる２の端部に組み込まれ、その振動面が頭部に当接するように配置される（例えば、特許文献１参照。）。   2. Description of the Related Art Conventionally, a so-called bone-conducting speaker that transmits sound by applying mechanical vibration to a bone of a head, such as a skull, has been widely known. Such a bone conduction speaker SP is attached to both ends of the headband 1 like the headset HS shown in FIG. 8A, or like the glasses GS shown in FIG. 8B, for example. In addition, it is incorporated at the end of the temple 2 and arranged so that its vibration surface comes into contact with the head (see, for example, Patent Document 1).

図９に示される従来公知の骨伝導スピーカ３は、ハウジング４を備え、このハウジング４内には、ヨーク５の中心磁極５Ａに巻回されたボイスコイル６と、このボイスコイル６の外周部に配置された磁石７と、この磁石７の上部に配置された振動板８が収容されている（特許文献２参照。）。骨伝導スピーカ３は、ヘッドセットＨＳや眼鏡ＧＳ等を介して、ハウジング４の振動面４Ａが頭部に当接するように配置される。   A conventionally known bone conduction speaker 3 shown in FIG. 9 includes a housing 4, in which a voice coil 6 wound around a central magnetic pole 5 A of a yoke 5 and an outer periphery of the voice coil 6 are provided. The magnet 7 arranged and the diaphragm 8 arranged above the magnet 7 are accommodated (see Patent Document 2). The bone conduction speaker 3 is disposed such that the vibration surface 4A of the housing 4 comes into contact with the head via the headset HS, the glasses GS, and the like.

この骨伝導スピーカ３のボイスコイル６に音声信号やオーディオ信号が入力されると、この信号に応じて振動板８が上下方向に振動する。そして、この振動がハウジング４に伝達される結果、ハウジング４の振動面４Ａが頭部を叩くようにして頭部の骨を振動し、骨伝導によって音が伝えられる。   When an audio signal or an audio signal is input to the voice coil 6 of the bone conduction speaker 3, the diaphragm 8 vibrates in the vertical direction according to the signal. As a result of this vibration being transmitted to the housing 4, the vibration surface 4A of the housing 4 vibrates the bone of the head as if hitting the head, and sound is transmitted by bone conduction.

しかしながら、この従来公知の骨伝導スピーカ３において感度を高めるには、振動面４Ａの面積を広げることによって頭部との接触面積を広くする必要がある。このため、装置が大型化しやすく、装着時に目立ちやすくなってしまう上に、広範囲に渡って頭部に所定の圧力が断続的に加えられることになるため、長時間使用した場合には、接触面において痛感を感じる場合があった。   However, in order to increase sensitivity in this conventionally known bone conduction speaker 3, it is necessary to increase the contact area with the head by expanding the area of the vibration surface 4A. For this reason, the device tends to become large and easily noticeable when worn, and a predetermined pressure is intermittently applied to the head over a wide range. There was a case of feeling pain.

Thus, the same problem as described above is solved by providing a bone conduction speaker having a magnetostrictive member that vibrates the bone of the head.

なお、本発明における「質量部材」とは、骨伝導スピーカの振動を受止めることができる、一定の質量を有する部材といい、例えば、眼鏡やヘッドセット等が該当する。   Note that the “mass member” in the present invention is a member having a certain mass capable of receiving the vibration of the bone conduction speaker, and includes, for example, glasses and a headset.

以下、本発明の実施例１、実施例２を図面に基づいて詳細に説明する。   Embodiments 1 and 2 of the present invention will be described below in detail with reference to the drawings.

図１〜図３に示されるように、本発明の実施例１に係る骨伝導スピーカ１０は、眼鏡ＧＳ１のつる１１の端部に連結された略円筒形状のアルミ製のケース１２を備えている。   As shown in FIGS. 1 to 3, the bone conduction speaker 10 according to the first embodiment of the present invention includes a substantially cylindrical aluminum case 12 connected to the end of the vine 11 of the glasses GS <b> 1. .

このケース１２内には、その中央位置近傍に配置された第１バイアス磁石１４と、この第１バイアス磁石１４を挟むように軸方向に分割して配置された超磁歪部材１６（１６Ａ、１６Ｂ）と、この超磁歪部材１６の更に軸方向外側に配置された第２、第３バイアス磁石１８、２０と、超磁歪部材１６の外周を囲むように配置された駆動コイル２２が収容されると共に、ケース１２の一端側に嵌められたネジ２４によって固定されている。   In the case 12, a first bias magnet 14 disposed in the vicinity of the central position thereof, and a giant magnetostrictive member 16 (16A, 16B) disposed in the axial direction so as to sandwich the first bias magnet 14 are disposed. And the second and third bias magnets 18 and 20 disposed further outside in the axial direction of the super magnetostrictive member 16 and the drive coil 22 disposed so as to surround the outer periphery of the super magnetostrictive member 16, and It is fixed by a screw 24 fitted to one end side of the case 12.

この骨伝導スピーカ１０は、耳裏近傍に、超磁歪部材１６の振動方向Ｘが頭部に対して略平行となるように配置される。   The bone conduction speaker 10 is disposed near the back of the ear so that the vibration direction X of the giant magnetostrictive member 16 is substantially parallel to the head.

超磁歪部材１６は、超磁歪素子を材料として用いている。ここで、「超磁歪素子」とは、希土類元素および／または特定の遷移金属などを主成分（例えば、テルビウム、ジスプロシウム、鉄など）とする粉末焼結合金あるいは単結晶合金から作られた磁歪素子をいい、外部から磁界が加えられると大きな変位を生じる性質を有している。   The giant magnetostrictive member 16 uses a giant magnetostrictive element as a material. Here, the “super magnetostrictive element” is a magnetostrictive element made of a powder sintered alloy or a single crystal alloy containing a rare earth element and / or a specific transition metal as a main component (eg, terbium, dysprosium, iron, etc.). It has the property of causing large displacement when a magnetic field is applied from the outside.

駆動コイル２２には、リード線２６を介してジャック２８が取り付けられている。この駆動コイル２２は、ジャック２８に接続される補聴器やオーディオ再生機器等からの音声信号やオーディオ信号に応じて、超磁歪部材１６の軸方向の磁界を変化させる。   A jack 28 is attached to the drive coil 22 via a lead wire 26. The drive coil 22 changes the magnetic field in the axial direction of the giant magnetostrictive member 16 in accordance with an audio signal or an audio signal from a hearing aid or an audio playback device connected to the jack 28.

次に、骨伝導スピーカ１０の作用について説明する。   Next, the operation of the bone conduction speaker 10 will be described.

リード線２６を介して、駆動コイル２２に音声信号やオーディオ信号が入力されると、これらの信号に応じた駆動電流によって駆動コイル２２のコイル磁界が変化する。このコイル磁界の変化に伴って、超磁歪部材１６が軸方向に伸縮し、ケース１２が頭部を擦るようにしてＸ方向に頭部の骨を振動する。そして、この振動が頭部の骨を介して脳に伝えられ、使用者は音声を認識することになる。   When an audio signal or an audio signal is input to the drive coil 22 via the lead wire 26, the coil magnetic field of the drive coil 22 is changed by a drive current corresponding to these signals. With the change of the coil magnetic field, the giant magnetostrictive member 16 expands and contracts in the axial direction, and the case 12 vibrates the bone of the head in the X direction so as to rub the head. This vibration is transmitted to the brain via the bone of the head, and the user recognizes the voice.

本発明の実施例１に係る骨伝導スピーカ１０によれば、振動方向の一方が眼鏡ＧＳ１（質量部材）に固定され、且つ、頭部を擦るようにして頭部の骨を振動させる超磁歪部材（振動子）１６を有してなるため、小型化を実現しつつ、同時に、頭部との接触面積を広くすることができ、装着時に目立ちにくい上に、感度を向上することができる。又、頭部に圧力が加えられることがなく、長時間使用した場合でも快適な装着感を維持することができる。   According to the bone conduction speaker 10 according to the first embodiment of the present invention, one of the vibration directions is fixed to the glasses GS1 (mass member), and the giant magnetostrictive member vibrates the bone of the head so as to rub the head. Since the (vibrator) 16 is provided, the contact area with the head can be increased at the same time while realizing miniaturization, and the sensitivity can be improved while being less noticeable at the time of wearing. In addition, no pressure is applied to the head, and a comfortable wearing feeling can be maintained even when used for a long time.

特に、振動子は超磁歪部材からなるため、より一層の小型化及び感度の向上が可能であると共に、細長い形状に成形することができ、眼鏡のつる等に容易に適用することができる。   In particular, since the vibrator is made of a giant magnetostrictive member, it is possible to further reduce the size and improve the sensitivity, and it can be formed into an elongated shape and can be easily applied to a temple of glasses.

更に、骨伝導スピーカ１０を耳裏近傍に配置しているため、骨伝導による感度を更に向上することができる上に、正面から見た場合に、装着が目立ちにくい。   Furthermore, since the bone conduction speaker 10 is disposed in the vicinity of the back of the ear, the sensitivity due to bone conduction can be further improved, and the wearing is less noticeable when viewed from the front.

次に、本発明の実施例２に係る骨伝導スピーカ３０について説明する。   Next, the bone conduction speaker 30 according to the second embodiment of the present invention will be described.

図４及び図５に示されるように、この骨伝導スピーカ３０は、超磁歪部材の振動方向が頭部に対して略垂直（図５中のＹ方向）となるように配置されており、骨伝導スピーカ３０が頭部を叩くようにして頭部の骨を振動するようになっている。又、この骨伝導スピーカ３０は、眼鏡ＧＳ２のつる３１の一部を構成している。なお、構造自体は実施例１に係る骨伝導スピーカ１０と同様であるため、その説明は省略する。   As shown in FIGS. 4 and 5, the bone conduction speaker 30 is arranged so that the vibration direction of the giant magnetostrictive member is substantially perpendicular to the head (Y direction in FIG. 5). The conduction speaker 30 vibrates the bones of the head as if hitting the head. Further, the bone conduction speaker 30 constitutes a part of the temple 31 of the glasses GS2. Since the structure itself is the same as that of the bone conduction speaker 10 according to the first embodiment, the description thereof is omitted.

本発明の実施例２に係る骨伝導スピーカ３０によれば、振動方向の一方が眼鏡ＧＳ２（質量部材）に固定され、且つ、頭部を叩くようにして頭部の骨を振動させる超磁歪部材を有してなるため、小型化及び感度の向上が可能であると共に、細長い形状に成形することができる。そのため、頭部を叩くように振動させるタイプの骨伝導スピーカでありながら、頭部との接触面積を広げることなく感度を向上することができる。又、実施例１に係る骨伝導スピーカ１０と同様に、長時間使用した場合でも快適な装着感を維持することができる上に、装着時に目立ちにくい。   According to the bone conduction speaker 30 according to the second embodiment of the present invention, one of the vibration directions is fixed to the glasses GS2 (mass member), and the giant magnetostrictive member that vibrates the bone of the head so as to strike the head. Therefore, it is possible to reduce the size and improve the sensitivity, and to form an elongated shape. Therefore, the sensitivity can be improved without increasing the contact area with the head, although the bone conduction speaker vibrates as if hitting the head. In addition, as with the bone conduction speaker 10 according to the first embodiment, a comfortable wearing feeling can be maintained even when used for a long time, and it is less noticeable when worn.

又、骨伝導スピーカ３０自体が眼鏡ＧＳ２のつる３１の一部を構成しているため、骨伝導スピーカ３０を、より一層目立たなくすることができる。   Further, since the bone conduction speaker 30 itself constitutes a part of the vine 31 of the glasses GS2, the bone conduction speaker 30 can be made even less conspicuous.

更に、骨伝導スピーカ３０は眼鏡ＧＳ２のつる３１の端部近傍に配置されているため、振動をより増大させることができる。   Furthermore, since the bone conduction speaker 30 is disposed in the vicinity of the end of the temple 31 of the glasses GS2, vibration can be further increased.

なお、本発明に係る骨伝導スピーカは、上記実施例１、実施例２における骨伝導スピーカ１０、３０の形状や構造等に限定されるものではなく、例えば、感度をそれほど高める必要がない場合には、超磁歪部材１６の代わりに磁歪部材を適用してもよい。又、実施例１においては、圧電セラミック等の圧電部材を振動子に適用してもよい。更に、ケース１２はアルミ製のものに限定されるものではない。なお、ケース１２は超磁歪部材１６の振動を伝達する役割を果たすため、振動伝達性に優れる弾性を有した非磁性部材で形成するのが好ましい。   The bone conduction speaker according to the present invention is not limited to the shape and structure of the bone conduction speakers 10 and 30 in the first and second embodiments. For example, when it is not necessary to increase the sensitivity so much. May employ a magnetostrictive member instead of the giant magnetostrictive member 16. In the first embodiment, a piezoelectric member such as a piezoelectric ceramic may be applied to the vibrator. Further, the case 12 is not limited to an aluminum one. Since the case 12 plays the role of transmitting the vibration of the giant magnetostrictive member 16, it is preferably formed of a nonmagnetic member having elasticity excellent in vibration transmission.

又、上記実施例１においては、骨伝導スピーカ１０を眼鏡ＧＳ１のつる１１の端部に取り付けた例を、更に、上記実施例２においては、骨伝導スピーカ３０が眼鏡ＧＳ２のつる３１の一部を構成するようにした例をそれぞれ示したが、本発明に係る骨伝導スピーカを用いた眼鏡はこれに限定されるものではない。   In the first embodiment, the bone conduction speaker 10 is attached to the end of the temple 11 of the glasses GS1, and in the second embodiment, the bone conduction speaker 30 is a part of the temple 31 of the glasses GS2. However, the glasses using the bone conduction speaker according to the present invention are not limited thereto.

従って、例えば、図６に示される眼鏡ＧＳ３のように、つる３２の端部を外耳道の側壁に当接するようにすれば、つる３２を介して外耳道からも骨伝導によって音を伝えることができ、更に感度を向上させることができる。   Therefore, for example, like the glasses GS3 shown in FIG. 6, if the end of the temple 32 is brought into contact with the side wall of the ear canal, sound can be transmitted from the ear canal via the temple 32 by bone conduction, Furthermore, the sensitivity can be improved.

更に、図７に示される眼鏡ＧＳ４のように、無線通信手段である無線通信装置３４を備え、つる３６が無線通信装置３４のアンテナを兼ねるようにすれば、補聴器やオーディオ再生機器等からの音声信号やオーディオ信号を無線で受信することができるようになる。   Furthermore, if a wireless communication device 34 as wireless communication means is provided as in the glasses GS4 shown in FIG. 7, and the vine 36 also serves as an antenna of the wireless communication device 34, sound from a hearing aid, an audio reproduction device, or the like will be provided. Signals and audio signals can be received wirelessly.

本発明に係る骨伝導スピーカ及びこれを用いた眼鏡は、補聴器やオーディオ再生機器等のスピーカとして適用することができる。   The bone conduction speaker according to the present invention and the glasses using the same can be applied as a speaker for a hearing aid, an audio playback device, or the like.
