本発明はスピーカユニット取付け構造および車両前部座席用シートに関する。 The present invention relates to a speaker unit mounting structure and a vehicle front seat .

自動車の車室内においては、音楽、放送、各種センサーからの注意喚起のための警報、ナビゲーション装置の案内音声などの各種音響情報が発せられる。
これらを聴取する手段として、一般に、図１のようにスピーカＳをドアＡやダッシュボードＢなどに取り付けている。ウーハなど容積を確保する必要がある場合は、座席の下やラッゲージＣなどに設置している。また、近年、ＤＶＤ5．1ｃｈ技術などの導入により、ルーフの中央部分Ｄに設置されることもある。 Various kinds of acoustic information such as music, broadcasting, alarms for alerting from various sensors, and guidance voices of navigation devices are emitted in the interior of a car.
As means for listening to these, a speaker S is generally attached to a door A, a dashboard B or the like as shown in FIG. When it is necessary to secure a volume such as a woofer, it is installed under the seat or in the luggage C. In recent years, it may be installed in the central portion D of the roof by introducing DVD 5.1ch technology or the like.

しかし、スピーカ設置位置は前部座席に座る者の耳位置とそもそも距離があり、後部座席に座っている者にとってはなおさら距離が遠く、しかも前部座席で音がかなり遮られるので、聴取効率、音響効果、臨場感などの点で十分とはいえなかった。こうした点を改善しようとしても、スピーカの設置には制約が非常に大きく、近い場所へのスピーカの配置は困難であった。
特開平８−３１０３１１号公報 However, the speaker installation position has a distance from the ear position of the person sitting on the front seat in the first place, farther away for those sitting on the rear seat, and the sound is considerably blocked by the front seat, so the listening efficiency, It was not enough in terms of sound effects and presence. Even if it was going to improve such a point, the installation of the speaker was very limited, and it was difficult to arrange the speaker in a close place.
JP-A-8-310311

The seat back board 4 is preferably made of synthetic resin, wood fiber board, metal plate, etc. having a large mass and rigidity, and a speaker mounting hole is provided at a required position, in this example, a portion relatively close to the seat. ing.

５はスピーカユニットであり、この例ではコーン型スピーカが使用され、出力面５０を後部座席に向けて前記シートバックボード４に取り付けられている。
すなわち、出力面５０の周りを取り囲むフランジ５ａをスピーカ取付け孔の外面に着座させ、残部を背もたれ部２Ａ内に挿入し、フランジ５ａに配したビス孔を通してねじをシートバックボード４にねじ込むことでスピーカユニット５を固定している。 Reference numeral 5 denotes a speaker unit. In this example, a cone-type speaker is used, and is attached to the seat back board 4 with the output surface 50 facing the rear seat.
That is, the flange 5a surrounding the output surface 50 is seated on the outer surface of the speaker mounting hole, the remaining portion is inserted into the backrest portion 2A, and the screw is screwed into the seat back board 4 through the screw hole arranged in the flange 5a. The unit 5 is fixed.

７は着座者の背面に接する側に張設された表皮であり、空気や音の透過性のよい材料、たとえばネットや織地，編地などで構成されている。 7 is a skin stretched on the side in contact with the back of the seated person, and is made of a material having good air and sound permeability, such as a net, a woven fabric, and a knitted fabric.

８は前記シートバックボード４と表皮７の間に充填されている空気層を十分に持ったクッション材であり、空気層を十分に持ったクッション材は、たとえば、ポリプロピレンなどの合成樹脂の網構造クッションなどで代表される軟質多孔性中空体からなっている。性状は成形体、不定形体など任意である。 8 is a cushioning material having a sufficient air layer filled between the seat back board 4 and the skin 7 , and the cushioning material having a sufficient air layer is, for example, a net structure of a synthetic resin such as polypropylene. It consists of a soft porous hollow body represented by a cushion. The properties are arbitrary, such as a molded body and an indefinite shape.

図４のように、背もたれ部２Ａの後部座席に臨むシートバックボード４にスピーカユニット５をその出力面５０を後部座席に向けて取り付けているが、背もたれ部２Ａには、スピーカユニット５に対応する位置に背もたれ部厚さ方向を貫通する穴２０を設け、ここにスピーカユニット５の内挿部分を囲繞する筒状空間部を構成するようにダクト部材９を埋め込んでいる。
前記ダクト部材９は質量，剛性の大きな合成樹脂、木質繊維板、金属板などからなっており、後端部すなわち表皮７に面する側に空気や音が漏れぬよう密閉する閉止部９０が設けられている。閉止部９０は前記スピーカユニット出力面５０と反対側の背部に対向しているが、本発明は前記閉止部９０の一部に厚さ方向を貫通する穴９００を設けている。 As shown in FIG. 4 , the speaker unit 5 is attached to the seat back board 4 facing the back seat of the backrest portion 2 </ b> A with the output surface 50 facing the back seat. The backrest portion 2 </ b> A corresponds to the speaker unit 5. A hole 20 penetrating in the thickness direction of the backrest portion is provided at the position, and the duct member 9 is embedded therein so as to constitute a cylindrical space portion surrounding the insertion portion of the speaker unit 5.
The duct member 9 is made of synthetic resin, wood fiber board, metal plate, etc. having a large mass and rigidity, and a closing portion 90 is provided on the rear end portion, that is, the side facing the skin 7 so as to prevent air and sound from leaking. It has been. The closing portion 90 faces the back portion opposite to the speaker unit output surface 50. In the present invention, a hole 900 penetrating in the thickness direction is provided in a part of the closing portion 90.

なお、スピーカユニット５は１個でなく、２個あるいはそれ以上取り付けてもよく、スピーカの種類も、コーン型に限らず、フラットパネル型、マイクロ型など各種のものを用いることができる。
スピーカユニット５の背もたれ部高さ方向での位置は、腰に近い部位が好適であるが、そのほか、肩に近い部位など適宜選定すればよい。 Note that the number of speaker units 5 is not limited to one, but two or more may be attached, and the type of speaker is not limited to the cone type, and various types such as a flat panel type and a micro type can be used.
The position of the speaker unit 5 in the height direction of the backrest part is preferably a part close to the waist, but in addition, a part close to the shoulder may be appropriately selected.

本発明においては、スピーカユニット５はバッフルとしてのシートバックボード４に出力面側がしっかりと固定される。しかも、ダクト部材９を用いるので、背もたれ部２の内部材質に影響されずに、また、背もたれ部２Ａに加えられる外力に対して安全にしかも後方に十分な振動用空間を確保しつつスピーカユニット５を最適位置に組み込むことができる。   In the present invention, the output surface side of the speaker unit 5 is firmly fixed to the seat back board 4 as a baffle. In addition, since the duct member 9 is used, the speaker unit 5 is not affected by the internal material of the backrest 2 and is safe from external force applied to the backrest 2A while ensuring a sufficient vibration space at the rear. Can be incorporated at the optimum position.

そして、スピーカの音響出力を後部座席３に向けて効率よく放射することができ、後部座席に座るものは、直近位置から迫力のある音響情報をダイレクトに聴取することができる。しかも、スピーカユニット５の背部に生じた振動がダクト部材９の空気を振動させて、スピーカユニット背部と対向する閉止部９０の厚さ方向を貫通する穴９００から放出されるので、前部に座っている者の背中に心地よい低音を刺激的に体感させ、臨場感にあふれた迫力のある音楽等の聴取を行うことができ、したがって、前部座席と後部座席を含めて効果を発揮することができる。 And the sound output of a speaker can be efficiently radiated | emitted toward the back seat 3, and what sits on a back seat can hear powerful acoustic information directly from the nearest position. Moreover, the vibration generated in the back portion of the speaker unit 5 vibrates the air in the duct member 9 and is emitted from the hole 900 penetrating the thickness direction of the closing portion 90 facing the speaker unit back portion, so that it sits in the front portion. It is possible to experience a pleasant bass sound on the back of a person who is living, and to listen to powerful music that is full of realism, so it can be effective including the front seat and the rear seat. it can.
