Description
本発明は、自動車のドア等に装着されて使用される車載用スピーカに係り、特に、スピーカの前面と車両の内装板等との間をシールするシール構造に関するものである。 The present invention relates to a vehicle-mounted speaker that is used by being mounted on an automobile door or the like, and more particularly to a seal structure that seals between a front surface of a speaker and an interior plate of a vehicle.
自動車のドア内にスピーカを取り付ける場合、ガラス窓と車体の隙間から塵埃や雨水等がドア内に侵入するので、これら塵埃や雨水等がドアの内装板を通過して車室内へ入り込むのを防止するために、スピーカの前面とドアの内装板との間をシールするというシール構造が広く採用されている。 When installing a speaker in the door of a car, dust and rainwater enter the door through the gap between the glass window and the vehicle body, thus preventing these dust and rainwater from entering the vehicle interior through the door interior panel. In order to achieve this, a sealing structure that seals between the front surface of the speaker and the interior plate of the door is widely adopted.
このようなシール構造の従来例として、特許文献１に記載されているように、ドアのインナに固定されるスピーカボックスにスピーカの構成部材であるフレームの鍔部をねじ止めし、このスピーカボックスにフレームの鍔部を囲むように突出する環状隔壁を形成すると共に、環状隔壁の前面にリング状のクッション部材を貼着したものが提案されている。 As a conventional example of such a seal structure, as described in Patent Document 1, a flange portion of a frame, which is a constituent member of a speaker, is screwed to a speaker box fixed to an inner door, and the speaker box is attached to the speaker box. An annular partition that protrudes so as to surround the flange of the frame is formed, and a ring-shaped cushion member is attached to the front surface of the annular partition.
また、他の従来例として、特許文献２に記載されているように、フレームの鍔部の前面側と裏面側にそれぞれリング状のクッション部材を貼着すると共に、これらクッション部材よりも内周側に位置する鍔部に貫通孔を穿設し、この貫通孔に挿通した取付ねじを用いてフレームを車両の支持部材に固定するようにしたものが提案されている。 As another conventional example, as described in Patent Document 2, ring-shaped cushion members are attached to the front surface side and the back surface side of the flange portion of the frame, respectively, and the inner peripheral side of these cushion members. There has been proposed a structure in which a through-hole is formed in a collar portion located at a position, and a frame is fixed to a vehicle support member using an attachment screw inserted into the through-hole.
特許文献１に記載されたスピーカのシール構造では、スピーカを環状隔壁の内側にねじ止めした状態でスピーカボックスがドア内に装着されると、ドアの内装板に形成された開口の縁部とスピーカボックスの環状隔壁との間でリング状のクッション部材が挟まれて圧縮状態となるため、このクッション部材によってスピーカを完全にシールすることができるようになっている。 In the speaker sealing structure described in Patent Document 1, when the speaker box is mounted in the door with the speaker screwed to the inside of the annular partition wall, the opening edge formed on the door interior plate and the speaker are mounted. Since the ring-shaped cushion member is sandwiched between the annular partition walls of the box and is in a compressed state, the speaker can be completely sealed by this cushion member.
特許文献２に記載されたスピーカのシール構造では、取付パネルにフレームをねじ止めした状態でスピーカがドア内に装着されると、取付パネルと鍔部の背面との間で裏面側のクッション部材が挟まれて圧縮状態になると共に、内装板の開口縁部と鍔部の前面との間で前面側のクッション部材が挟まれて圧縮状態になるため、これら両クッション部材によってスピーカを完全にシールすることができるようになっている。 In the speaker seal structure described in Patent Document 2, when the speaker is mounted in the door in a state where the frame is screwed to the mounting panel, a cushion member on the back surface side is provided between the mounting panel and the back surface of the flange. While being sandwiched and compressed, the front cushion member is sandwiched between the opening edge of the interior panel and the front surface of the collar, and the speaker is completely sealed by both cushion members. Be able to.
しかし、特許文献１に記載された前者の従来例では、スピーカを包囲するスピーカボックスの環状隔壁にリング状のクッション部材を貼着し、このクッション部材によってスピーカをシールするようにしているため、ドア内の限られたスペースに大型なスピーカボックスを固定する必要があり、スピーカの設置スペースが大きく制約を受けたり、部品コストが高騰する等の問題があった。 However, in the former conventional example described in Patent Document 1, a ring-shaped cushion member is attached to an annular partition wall of a speaker box surrounding the speaker, and the speaker is sealed by this cushion member. There is a problem that a large speaker box needs to be fixed in a limited space, and the installation space of the speaker is greatly restricted, and the cost of parts increases.
また、特許文献２に記載された後者の従来例では、ねじ挿通用の貫通孔が穿設された鍔部に対して、貫通孔よりも外周側にクッション部材が貼着されているため、フレームの鍔部に予めクッション部材が貼着されていても、クッション部材の内周側に露出する貫通孔を利用してスピーカをねじ止めすることができる。しかし、フレームの外径寸法の制約等によって貫通孔の外周側にクッション部材を貼着するスペースを確保することが困難な場合は、クッション部材を貼着しない状態でスピーカをねじ止めした後に、貫通孔の上から鍔部にクッション部材を貼らなければならないため、スピーカを取り付ける作業者がクッション部材を貼ることとなる。すなわち、オプションタイプのスピーカの場合はディーラーがクッション部材を貼り付け、市販タイプのスピーカの場合は一般ユーザがクッション部材を貼り付けることになるが、クッション部材は柔らかくて変形しやすい材料で形成されており、このようなクッション部材を両面テープを用いてフレームの鍔部に貼り付けるのは面倒であるため、スピーカの取付作業が煩雑になるという問題が発生する。 Further, in the latter conventional example described in Patent Document 2, a cushion member is attached to the outer peripheral side of the through hole with respect to the collar portion in which the through hole for screw insertion is formed. Even if a cushion member is attached in advance to the flange portion, the speaker can be screwed using a through hole exposed on the inner peripheral side of the cushion member. However, if it is difficult to secure a space for attaching the cushion member to the outer periphery of the through-hole due to restrictions on the outer diameter of the frame, etc., the speaker is screwed in without attaching the cushion member. Since the cushion member has to be pasted from the top of the hole to the buttocks, the operator who attaches the speaker will paste the cushion member. That is, in the case of an optional type speaker, the dealer attaches the cushion member, and in the case of a commercially available type speaker, the general user attaches the cushion member, but the cushion member is made of a soft and easily deformable material. In addition, since it is troublesome to attach such a cushion member to the flange portion of the frame using a double-sided tape, there arises a problem that the task of attaching the speaker becomes complicated.
本発明は、このような従来技術の実情に鑑みてなされたもので、その目的は、車両への取付作業が簡単で高いシール性を確保できる車載用スピーカを提供することにある。 The present invention has been made in view of the actual situation of the prior art, and an object thereof is to provide a vehicle-mounted speaker that can be easily attached to a vehicle and can ensure high sealing performance.
上記の目的を達成するために、本発明の車載用スピーカは、前側で振動板を支持し後側で磁気回路を支持するフレームの前端部に円環状の鍔部が設けられていると共に、この鍔部に取付ねじを挿通させるための貫通孔が設けられており、前記フレームが前記取付ねじを用いて車両の支持部材に取り付けられる車載用スピーカにおいて、前記フレームは前記鍔部の内周側で前方に向かって突出する支持壁部を有し、前記鍔部の前面に前記貫通孔を露出させるように本体クッション部材が分断部を有して環状に貼着されていると共に、前記支持壁部に前記分断部を塞ぐように補助クッション部材が貼着されており、前記補助クッション部材を変形させることによって前記貫通孔が露出可能となるようにした。 In order to achieve the above object, the vehicle-mounted speaker according to the present invention is provided with an annular flange at the front end of the frame that supports the diaphragm on the front side and the magnetic circuit on the rear side. In the vehicle-mounted speaker in which a through-hole for allowing a mounting screw to pass through the flange is provided, and the frame is mounted to a vehicle support member using the mounting screw, the frame is located on the inner peripheral side of the flange. A support wall portion protruding forward, and a main body cushion member having a dividing portion so as to expose the through hole on the front surface of the flange portion, and being annularly attached, and the support wall portion An auxiliary cushion member is attached so as to block the dividing portion, and the through hole can be exposed by deforming the auxiliary cushion member.
このように構成された車載用スピーカでは、予めフレームの鍔部に本体クッション部材が分断部を有して環状に貼着されており、その分断部の内底面に取付ねじを挿通させるための貫通孔が設けられていると共に、鍔部の内周側から前方に突出する支持壁部に分断部を塞ぐように補助クッション部材が貼着されているため、補助クッション部材をめくって貫通孔を露出させた状態で、この貫通孔に取付ねじを挿通してフレームをドアのインナ等の支持部材に取り付けた後に、補助クッション部材を再び分断部に嵌め込めば、鍔部の前面に本体クッション部材と補助クッション部材がリング状に連続したシール構造を形成することができる。したがって、スピーカを取り付ける作業者が面倒な本体クッション部材の貼着作業を行わなくて済み、補助クッション部材をめくってねじ止めしてから元に戻すという簡単な作業により、スピーカの前面と車両の内装板との間を確実にシールすることができる。 In the vehicle-mounted speaker configured in this way, the main body cushion member has a dividing portion in advance on the collar portion of the frame and is attached in an annular shape, and a through-hole for inserting a mounting screw into the inner bottom surface of the dividing portion A hole is provided and an auxiliary cushion member is attached to the support wall that protrudes forward from the inner peripheral side of the buttock so as to close the dividing portion. In this state, after inserting a mounting screw into this through hole and attaching the frame to a support member such as an inner door, the auxiliary cushion member is fitted into the dividing portion again. A seal structure in which the auxiliary cushion member is continuous in a ring shape can be formed. Therefore, the operator who installs the speaker does not have to perform the troublesome sticking work of the main body cushion member, and the front of the speaker and the interior of the vehicle can be obtained by a simple operation of turning the auxiliary cushion member and screwing it back. The space between the plates can be reliably sealed.
上記の構成において、本体クッション部材と補助クッション部材が断面同一形状の弾性シール材料であると、長尺状の弾性シール材料を異なる長さで切断することにより、同じ弾性シール材料から本体クッション部材と補助クッション部材を形成することができて好ましい。 In the above configuration, when the main body cushion member and the auxiliary cushion member are elastic seal materials having the same cross-sectional shape, the main body cushion member and the main body cushion member are separated from the same elastic seal material by cutting the long elastic seal material with different lengths. An auxiliary cushion member can be formed, which is preferable.
本発明の車載用スピーカによれば、わざわざ面倒な本体クッション部材の貼着作業を行わなくても、補助クッション部材をめくってねじ止めしてから元に戻すというという簡単な作業によって、スピーカの前面に高いシール性を確保することができる。 According to the vehicle-mounted speaker of the present invention, the front surface of the speaker can be obtained by a simple operation of turning the auxiliary cushion member, screwing it, and then returning it to the original position without performing bothersome work of attaching the body cushion member. High sealing performance can be ensured.
発明の実施の形態について図面を参照して説明すると、図１に示すように、本発明の実施形態例に係る車載用スピーカ１は、自動車のドア内に取り付けられて車室内へ再生音を放出するというものである。このスピーカ１は、磁気ギャップを有する磁気回路２と、磁気ギャップに配置されて通電時に電磁相互作用で駆動されるボイスコイル３と、ボイスコイル３に連動して振動する略円錐形状の振動板４と、これらボイスコイル３および振動板４を弾性的に支持している円環状のダンパー５と、振動板４の外周部およびダンパー５の外周部を保持しているフレーム６とによって主に構成されており、フレーム６は磁気回路２の構成部材であるヨークに締結固定されている。 An embodiment of the invention will be described with reference to the drawings. As shown in FIG. 1, an in-vehicle speaker 1 according to an embodiment of the present invention is mounted in a door of an automobile and emits reproduced sound into the vehicle interior. It is to do. The speaker 1 includes a magnetic circuit 2 having a magnetic gap, a voice coil 3 disposed in the magnetic gap and driven by electromagnetic interaction when energized, and a substantially conical diaphragm 4 that vibrates in conjunction with the voice coil 3. And an annular damper 5 that elastically supports the voice coil 3 and the diaphragm 4 and a frame 6 that holds the outer periphery of the diaphragm 4 and the outer periphery of the damper 5. The frame 6 is fastened and fixed to a yoke that is a component of the magnetic circuit 2.
フレーム６の前端部には円環状の鍔部７が一体的に設けられており、図２や図４に示すように、この鍔部７の一部は径方向の外方へ突出する拡張部７ａとなっている。鍔部７の内周側にはリング状の支持壁部７ｂが前方に向かって突設されており、この支持壁部７ｂの外周側における鍔部７には３つの貫通孔８が約１２０度の等間隔を保って設けられている。３つの貫通孔８のうちの１つは拡張部７ａに設けられているが、残り２つの貫通孔８は鍔部７に形成された凹部７ｃの底面に設けられており、これら凹部７ｃの内周面に支持壁部７ｂの一部が連続している。各貫通孔８はスピーカ固定用の取付ねじ９よりも幾分大径のばか孔となっており、詳細については後述するが、取付ねじ９を各貫通孔８に挿入して車両の支持部材１０にねじ止めすることにより、スピーカ１は自動車のドア内に取り付けられるようになっている（図１参照）。 An annular flange portion 7 is integrally provided at the front end portion of the frame 6, and as shown in FIGS. 2 and 4, a part of the flange portion 7 protrudes outward in the radial direction. 7a. A ring-shaped support wall 7b protrudes forward on the inner peripheral side of the flange 7, and the three through holes 8 are approximately 120 degrees in the flange 7 on the outer periphery of the support wall 7b. Are provided at equal intervals. One of the three through-holes 8 is provided in the extended portion 7a, but the remaining two through-holes 8 are provided in the bottom surface of the recess 7c formed in the flange portion 7, and the inside of these recesses 7c. A part of the support wall 7b is continuous with the peripheral surface. Each through-hole 8 is a flawed hole having a diameter slightly larger than that of the mounting screw 9 for fixing the speaker. As will be described in detail later, the mounting screw 9 is inserted into each through-hole 8 to support the vehicle support member 10. The speaker 1 can be mounted in the door of the automobile by screwing to (see FIG. 1).
鍔部７の前面には２つの本体クッション部材１１Ａ，１１Ｂが両面テープ１２を用いて貼り付けられており、これら本体クッション部材１１Ａ，１１Ｂは凹部７ｃの真上に位置する分断部Ｓを有して環状に連続している。すなわち、一方の凹部７ｃから拡張部７ａの外側を通って他方の凹部７ｃに至る領域に長い方の本体クッション部材１１Ａが貼り付けられていると共に、２つの凹部７ｃで挟まれた円弧状の領域に短い方の本体クッション部材１１Ｂが貼り付けられており、これら両本体クッション部材１１Ａ，１１Ｂの端面間にそれぞれ分断部Ｓが形成されている。 Two main body cushion members 11A and 11B are affixed to the front surface of the collar portion 7 using a double-sided tape 12, and the main body cushion members 11A and 11B have a dividing portion S positioned immediately above the recess 7c. In a ring. That is, the longer main body cushion member 11A is attached to a region extending from one recessed portion 7c to the other recessed portion 7c through the outside of the extended portion 7a, and an arc-shaped region sandwiched between the two recessed portions 7c. The shorter main body cushion member 11B is affixed to each other, and a dividing portion S is formed between the end surfaces of both the main body cushion members 11A and 11B.
凹部７ｃと対向する支持壁部７ｂの内周面には補助クッション部材１３が両面テープ１４を用いて貼り付けられており、分断部Ｓはこの補助クッション部材１３によって塞がれている。補助クッション部材１３は支持壁部７ｂを固定端としてめくり上げることが可能であり、このように補助クッション部材１３をめくり上げて分断部Ｓを開放すると、分断部Ｓ内に凹部７ｃと貫通孔８が露出した状態となる。 An auxiliary cushion member 13 is affixed to the inner peripheral surface of the support wall portion 7b facing the concave portion 7c using a double-sided tape 14, and the dividing portion S is closed by the auxiliary cushion member 13. The auxiliary cushion member 13 can be turned up with the support wall portion 7b as a fixed end. When the auxiliary cushion member 13 is turned up in this way and the dividing portion S is opened, the recessed portion 7c and the through hole 8 are formed in the dividing portion S. Will be exposed.
補助クッション部材１３は本体クッション部材１１Ａ，１１Ｂと長さ寸法を異にするだけで断面形状や材料は同じであり、これら本体クッション部材１１Ａ，１１Ｂと補助クッション部材１３は、いずれも発泡ウレタン等からなる断面角形の長尺状の弾性シール材料を所定長さで切断したものからなる。なお、分断部Ｓの径方向の長さに対して補助クッション部材１３の方が若干長めに設定されているため，補助クッション部材１３は本体クッション部材１１Ａ，１１Ｂの外周面から僅かに突出しており、この突出部分によって補助クッション部材１３をめくり易くしている。また、分断部Ｓの周方向の長さに対して補助クッション部材１３の方が幾分大きめに設定されているため、補助クッション部材１３を分断部Ｓ内に挿入すると、補助クッション部材１３は周方向に圧縮された状態で本体クッション部材１１Ａ，１１Ｂの端面に接触することになる。 The auxiliary cushion member 13 is the same in cross-sectional shape and material as the main body cushion members 11A and 11B, but the length and dimensions are different. The main body cushion members 11A and 11B and the auxiliary cushion member 13 are made of urethane foam or the like. A long elastic sealing material having a square cross section is cut to a predetermined length. Since the auxiliary cushion member 13 is set slightly longer than the radial length of the dividing portion S, the auxiliary cushion member 13 slightly protrudes from the outer peripheral surface of the main body cushion members 11A and 11B. The auxiliary cushion member 13 is easily turned by this protruding portion. Further, since the auxiliary cushion member 13 is set somewhat larger than the circumferential length of the dividing portion S, when the auxiliary cushion member 13 is inserted into the dividing portion S, the auxiliary cushion member 13 is It will contact the end faces of the main body cushion members 11A and 11B in a state compressed in the direction.
したがって、図４に示すように、ドアに取り付ける前のスピーカ１を前方から見ると、本体クッション部材１１Ａ，１１Ｂで挟まれた２つの分断部Ｓがそれぞれ補助クッション部材１３によって塞がれ、これら２本の本体クッション部材１１Ａ，１１Ｂと２つの補助クッション部材１３がリング状に連結された状態となっている。そして、各補助クッション部材１３によって２つの貫通孔８が覆われていると共に、残り１つの貫通孔８が長い方のクッション部材１１Ａよりも内側の拡張部７ａに露出した状態となっている。 Therefore, as shown in FIG. 4, when the speaker 1 before being attached to the door is viewed from the front, the two divided portions S sandwiched between the main body cushion members 11A and 11B are respectively closed by the auxiliary cushion members 13, and these 2 The main body cushion members 11A and 11B and the two auxiliary cushion members 13 are connected in a ring shape. Each auxiliary cushion member 13 covers the two through holes 8 and the remaining one through hole 8 is exposed to the extended portion 7a on the inner side of the longer cushion member 11A.
前述したように、本実施形態例に係る車載用スピーカ１は、その製造工程で予めフレーム６の鍔部７の前面に本体クッション部材１１Ａ，１１Ｂが分断部Ｓを介して環状に貼着されていると共に、鍔部７の内周側から前方に突出する支持壁部７ｂに補助クッション部材１３が貼着されており、この補助クッション部材１３が分断部Ｓ内に挿入されているため、分断部Ｓの内底面に設けられた２つの貫通孔８はそれぞれ補助クッション部材１３によって覆い隠され、残り１つの貫通孔８が長い方の本体クッション部材１１Ａで包囲された拡張部７ａに露出している。 As described above, the in-vehicle speaker 1 according to the present embodiment has the body cushion members 11A and 11B attached in a ring shape to the front surface of the flange portion 7 of the frame 6 via the dividing portion S in advance in the manufacturing process. In addition, the auxiliary cushion member 13 is attached to the support wall portion 7b that protrudes forward from the inner peripheral side of the collar portion 7, and the auxiliary cushion member 13 is inserted into the divided portion S. The two through holes 8 provided on the inner bottom surface of S are each covered with an auxiliary cushion member 13, and the remaining one through hole 8 is exposed to the extended portion 7a surrounded by the longer main body cushion member 11A. .
次に、このように構成された車載用スピーカ１を自動車のドア内に取り付ける手順について、図１と図５を参照しつつ説明する。 Next, a procedure for mounting the vehicle-mounted speaker 1 configured as described above in the door of the automobile will be described with reference to FIGS. 1 and 5.
まず、内装板１５を取り外して作業スペースを確保した状態でスピーカ１をドア内に挿入し、ドアのインナ等の支持部材１０に弾性スペーサ１６を介して鍔部７の背面を押し付ける。このとき、図５（ａ）に示すように、鍔部７の凹部７ｃに設けられた貫通孔８は補助クッション部材１３によって覆い隠されている。次に、図５（ｂ）に示すように、補助クッション部材１３をめくり上げて貫通孔８を露出させ、この状態で鍔部７の前方から貫通孔８に取付ねじ９を挿入した後、取付ねじ９をドライバー等の治具１７で締め付けてねじ止めする。その際、補助クッション部材１３は分断部Ｓの径方向の長さに対して若干長めに設定されており、本体クッション部材１１Ａ，１１Ｂの外周面から補助クッション部材１３が僅かに飛び出しているため、補助クッション部材１３の位置を容易に確認することができると共に、補助クッション部材１３を容易にめくり上げることができる。 First, the speaker 1 is inserted into the door in a state where the interior plate 15 is removed and a work space is secured, and the back surface of the flange portion 7 is pressed against the support member 10 such as the inner of the door via the elastic spacer 16. At this time, as shown in FIG. 5A, the through hole 8 provided in the concave portion 7 c of the flange portion 7 is covered with the auxiliary cushion member 13. Next, as shown in FIG. 5 (b), the auxiliary cushion member 13 is turned up to expose the through hole 8, and the mounting screw 9 is inserted into the through hole 8 from the front of the flange portion 7 in this state. The screw 9 is tightened with a jig 17 such as a screwdriver and screwed. At that time, the auxiliary cushion member 13 is set slightly longer than the radial length of the dividing portion S, and the auxiliary cushion member 13 slightly protrudes from the outer peripheral surface of the main body cushion members 11A and 11B. The position of the auxiliary cushion member 13 can be easily confirmed, and the auxiliary cushion member 13 can be easily turned up.
しかる後、めくり上げた補助クッション部材１３を元に戻して分断部Ｓ内に嵌め込むと、図３に示すように、取付ねじ９が補助クッション部材１３によって覆い隠された状態となり、２本の本体クッション部材１１Ａ，１１Ｂと２つの補助クッション部材１３が再びリング状に連結される。その際、補助クッション部材１３は分断部Ｓの周方向の長さに対して幾分大きめに設定されており、分断部Ｓ内で補助クッション部材１３は圧縮された状態で本体クッション部材１１Ａ，１１Ｂの端面と接するため、本体クッション部材１１Ａ，１１Ｂと補助クッション部材１３間の気密性が高められると共に、分断部Ｓに対する補助クッション部材１３の保持力が高められて外れにくくなる。なお、拡張部７ａに設けられた貫通孔８については、そのまま鍔部７の前方から貫通孔８に取付ねじ９を挿入し、この取付ねじ９を締め付けてねじ止めする。 Thereafter, when the auxiliary cushion member 13 that has been turned up is returned to the original position and fitted into the dividing portion S, the mounting screw 9 is covered with the auxiliary cushion member 13 as shown in FIG. The main body cushion members 11A and 11B and the two auxiliary cushion members 13 are connected in a ring shape again. At this time, the auxiliary cushion member 13 is set to be slightly larger than the circumferential length of the divided portion S, and the auxiliary cushion member 13 is compressed in the divided portion S in the main body cushion members 11A and 11B. Therefore, the airtightness between the main body cushion members 11A and 11B and the auxiliary cushion member 13 is enhanced, and the holding force of the auxiliary cushion member 13 with respect to the dividing portion S is increased, so that it is difficult to come off. In addition, about the through-hole 8 provided in the expansion part 7a, the attachment screw 9 is inserted in the through-hole 8 from the front of the collar part 7 as it is, and this attachment screw 9 is tightened and screwed.
そして、このように本体クッション部材１１Ａ，１１Ｂの分断部Ｓを補助クッション部材１３で塞いだ後、図１に示すように、ドアに内装板１５を取り付けてスピーカ１の前方を覆うと、内装板１５に設けられた環状突起１５ａが本体クッション部材１１Ａ，１１Ｂと補助クッション部材１３に食い込むため、スピーカ１の前面とドアの内装板１５との間が本体クッション部材１１Ａ，１１Ｂと補助クッション部材１３によって完全にシールされる。なお、内装板１５には振動板４の前方を覆うグリル１８が設けられているため、スピーカ１からの再生音はグリル１８を通過して車室内へ放出される。 Then, after the divided portion S of the main body cushion members 11A and 11B is closed with the auxiliary cushion member 13 as shown in FIG. 1, the inner plate 15 is attached to the door to cover the front of the speaker 1 as shown in FIG. Since the annular protrusion 15a provided on 15 bites into the body cushion members 11A and 11B and the auxiliary cushion member 13, the space between the front surface of the speaker 1 and the interior panel 15 of the door is between the body cushion members 11A and 11B and the auxiliary cushion member 13. Fully sealed. Since the interior plate 15 is provided with a grill 18 that covers the front of the diaphragm 4, the reproduced sound from the speaker 1 passes through the grill 18 and is released into the vehicle interior.
以上説明したように、本実施形態例に係る車載用スピーカ１では、自動車に取り付ける前の製造工程で予めフレーム６の鍔部７の前面に本体クッション部材１１Ａ，１１Ｂが分断部Ｓを介して環状に貼着され、この分断部Ｓの内底面に取付ねじ９を挿通させるための貫通孔８が設けられていると共に、鍔部７の内周側から前方に突出する支持壁部７ｂに補助クッション部材１３が貼着され、この補助クッション部材１３が分断部Ｓ内に挿入されて貫通孔８を覆っているため、補助クッション部材１３をめくって貫通孔８を露出させた状態で、取付ねじ９を貫通孔８に挿通してフレーム６をドアのインナ等の支持部材１０に取り付けた後に、補助クッション部材１３を元に戻して分断部Ｓに嵌め込めば、鍔部７の前面に本体クッション部材１１Ａ，１１Ｂと補助クッション部材１３がリング状に連続したシール構造を形成することができる。したがって、スピーカ１を取り付ける作業者にとって面倒なクッション部材の貼着作業が不要となり、補助クッション部材１３をめくってねじ止めしてから元に戻すという簡単な作業により、スピーカ１の前面と車両の内装板１５との間を確実にシールすることができる。 As described above, in the vehicle-mounted speaker 1 according to the present embodiment, the main body cushion members 11A and 11B are annularly connected to the front surface of the flange portion 7 of the frame 6 via the dividing portion S in the manufacturing process before being attached to the automobile. A through-hole 8 is provided on the inner bottom surface of the dividing portion S to allow the mounting screw 9 to be inserted, and an auxiliary cushion is provided on the support wall portion 7b protruding forward from the inner peripheral side of the flange portion 7. Since the member 13 is affixed and the auxiliary cushion member 13 is inserted into the dividing portion S and covers the through hole 8, the mounting screw 9 is exposed in a state in which the auxiliary cushion member 13 is turned to expose the through hole 8. Is inserted into the through-hole 8 and the frame 6 is attached to a support member 10 such as an inner door, and then the auxiliary cushion member 13 is returned to its original position and fitted into the dividing portion S. 11 , 11B and the auxiliary cushion member 13 can form a sealing structure which is continuous in a ring shape. Therefore, the work of attaching the cushion member, which is troublesome for the operator who installs the speaker 1, is unnecessary, and the front surface of the speaker 1 and the interior of the vehicle can be obtained by a simple operation of turning the auxiliary cushion member 13 and screwing it back. The space between the plates 15 can be reliably sealed.
また、本体クッション部材１１Ａ，１１Ｂと補助クッション部材１３は断面角形の弾性シール材料を所定長さで切断したものであるため、同じ弾性シール材料から本体クッション部材１１Ａ，１１Ｂと補助クッション部材１３を形成することができ、部品コストの低減化が図られている。 Further, since the main body cushion members 11A and 11B and the auxiliary cushion member 13 are formed by cutting an elastic seal material having a square cross section at a predetermined length, the main body cushion members 11A and 11B and the auxiliary cushion member 13 are formed from the same elastic seal material. The cost of parts can be reduced.
なお、上記実施形態例では、フレーム６の鍔部７に３本の取付ねじ９に対応する３つの貫通孔８を設け、そのうちの２つを本体クッション部材１１Ａ，１１Ｂで挟まれた２箇所の分断部Ｓの内底面に露出させ、残り１つを本体クッション部材１１Ａの内側の拡張部７ａに露出させた場合について説明したが、貫通孔８を露出させる分断部Ｓは少なくとも１箇所あれば良く、例えば、１つの貫通孔８だけを分断部Ｓの内底面に露出させたり、３つ全ての貫通孔８を分断部Ｓの内底面に露出させるようにしても良い。 In the above-described embodiment, three through holes 8 corresponding to the three mounting screws 9 are provided in the flange portion 7 of the frame 6, and two of them are sandwiched between the body cushion members 11A and 11B. Although the case where it was exposed to the inner bottom face of the parting part S and the remaining one was exposed to the extended part 7a inside the main body cushion member 11A was described, the parting part S that exposes the through hole 8 may be at least one place. For example, only one through hole 8 may be exposed on the inner bottom surface of the dividing portion S, or all three through holes 8 may be exposed on the inner bottom surface of the dividing portion S.
また、フレーム６を支持部材１０に固定する取付ねじ９の数は３本に限定されず、例えば、１本の取付ねじと複数のフックを用いてフレーム６を支持部材１０に固定することも可能である。その場合、鍔部７の前面に分断部Ｓが１箇所だけできるように本体クッション部材を貼着し、この分断部Ｓの内底面にのみ貫通孔８を露出させると共に、鍔部７の背面に支持部材１０と係脱可能なフック等を設ければ良い。 Further, the number of mounting screws 9 for fixing the frame 6 to the support member 10 is not limited to three. For example, the frame 6 can be fixed to the support member 10 using one mounting screw and a plurality of hooks. It is. In that case, the main body cushion member is stuck on the front surface of the collar portion 7 so that only one part S is formed, and the through hole 8 is exposed only on the inner bottom surface of the part S, and on the rear surface of the collar portion 7. What is necessary is just to provide the hook etc. which can be engaged / disengaged with the support member 10. FIG.
また、上記実施形態例では、補助クッション部材１３が貼着される支持壁部７ｂをリング状に形成しているが、この支持壁部７ｂは少なくとも貫通孔８と対向する位置に形成されていれば良い。すなわち、支持壁部７ｂは貫通孔８の内側にのみ立設されて断続的に形成されていても良い。 In the above embodiment, the support wall portion 7b to which the auxiliary cushion member 13 is attached is formed in a ring shape, but the support wall portion 7b is formed at a position facing at least the through hole 8. It ’s fine. That is, the support wall portion 7 b may be formed intermittently by being erected only inside the through hole 8.
