The speaker cord is equipped with signal wire for supplying an electric signal to the speaker body, a fall prevention wire for preventing the speaker body from falling, a cover material for covering both the signal wire and the fall prevention wire, and an attachment part for attaching the signal wire and the fall prevention wire through the cover material to an external body structure. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

本発明は、スピーカ及びスピーカ用コードに関する。   The present invention relates to a speaker and a speaker cord.

従来、例えば、スピーカコードを天井にあるフックに掛けることでスピーカ本体を支持するスピーカが知られている（例えば特許文献１参照）。しかしながら、スピーカコードのみでスピーカ本体を支えているので、万が一スピーカコードが破断してしまうと、そのままスピーカ本体が落下することになっていた。
これを防止すべく、近年ではスピーカコードとは別体の落下防止用ワイヤをスピーカ本体に取り付けたスピーカが開発されている。具体的に、スピーカ１００には、図９に示すようにスピーカ本体１０１の裏面には、スピーカコード１０２と、落下防止用ワイヤ１０３とが接続されている。スピーカコード１０２は、アンプに接続されていて、アンプから出力された電気信号をスピーカ本体１０１に供給するようになっている。一方、落下防止用ワイヤ１０３は、その先端部に固定リング１０４が設けられていて、その固定リング１０４にネジ１０５を挿通し壁１０６に螺合することで、落下防止用ワイヤ１０３が壁１０６に固定されるようになっている。これにより、スピーカ本体１０１が落下防止用ワイヤ１０３を介して壁１０６に連結されて、スピーカ本体の落下が防止されることになる。
実開平２−１０６８７号公報 Conventionally, for example, a speaker that supports a speaker body by hanging a speaker cord on a hook on a ceiling is known (see, for example, Patent Document 1). However, since the speaker body is supported only by the speaker cord, if the speaker cord is broken, the speaker body is to be dropped as it is.
In order to prevent this, a speaker in which a fall prevention wire separate from the speaker cord is attached to the speaker body has been developed in recent years. Specifically, as shown in FIG. 9, a speaker cord 102 and a fall prevention wire 103 are connected to the speaker 100 on the back surface of the speaker body 101 as shown in FIG. 9. The speaker cord 102 is connected to an amplifier, and supplies an electrical signal output from the amplifier to the speaker body 101. On the other hand, the fall prevention wire 103 is provided with a fixing ring 104 at its tip, and a screw 105 is inserted into the fixation ring 104 and screwed into the wall 106 so that the fall prevention wire 103 is attached to the wall 106. It is supposed to be fixed. As a result, the speaker main body 101 is connected to the wall 106 via the fall prevention wire 103, and the speaker main body is prevented from falling.
Japanese Utility Model Publication No. 2-10687

ところで、上述したようにスピーカコードと、落下防止用ワイヤとがそれぞれ設けられていると、スピーカコードだけが設けられたものと比べても配線が煩雑となってしまっていた。特に、スピーカの設置時にスピーカコードだけを取り付ければ音は鳴るので、ユーザによっては落下防止用ワイヤを取り付けないことも考えられ、落下防止機能を発揮できないおそれもある。   By the way, if the speaker cord and the fall prevention wire are respectively provided as described above, the wiring becomes complicated as compared with the case where only the speaker cord is provided. In particular, if only the speaker cord is attached at the time of installing the speaker, a sound is produced. Therefore, depending on the user, it may be possible not to attach the fall prevention wire, and the fall prevention function may not be exhibited.

そこで本発明の課題は、配線の見栄えをよくしつつも、スピーカの落下防止機能を高めることである。   Accordingly, an object of the present invention is to enhance the fall prevention function of the speaker while improving the appearance of the wiring.

また、取付部は、外部の構造体に取り付けなければ信号線が導通しない構造となっているため、スピーカから音を出すには取付部の固定が必須となる。したがって、落下防止ワイヤを確実に機能させることができる。 According to the present invention, since the signal wire and the fall prevention wire are integrated together by the cover material, the wiring can be simplified and the appearance is improved. Furthermore, by attaching the speaker cord to the speaker main body, the signal wire and the fall prevention wire are securely attached to the speaker main body. If the speaker cord is attached to the external structure by the attachment portion, the fall prevention function can be exhibited. Here, the fall prevention wires are integrated together with the signal wires, so even if the speaker body drops from a fixed position, it is more surely prevented from falling than the speaker cords that consist only of signal wires. can do.
In addition, since the attachment portion has a structure in which the signal line does not conduct unless attached to an external structure, the attachment portion must be fixed in order to emit sound from the speaker. Therefore, the fall prevention wire can function reliably.

図３は線材保持部３６の概略構成を示す正面図であり、図４は側断面図、図５は線材保持部３６の内部構成を示す正面図である。これら図３〜５に示すように、線材保持部３６には、基台３８と、基台３８の正面側を覆う蓋部３９とが設けられている。   3 is a front view showing a schematic configuration of the wire holding unit 36, FIG. 4 is a side sectional view, and FIG. 5 is a front view showing an internal configuration of the wire holding unit 36. As shown in FIG. As shown in FIGS. 3 to 5, the wire holding unit 36 is provided with a base 38 and a lid 39 that covers the front side of the base 38.

基台３８には、信号用線材３１，３２及び落下防止用ワイヤ３３が固定される基板４０と、基板４０の周囲から立設する壁部４１と、基板４０に形成された貫通孔４２とが備えられている。
基板４０は、絶縁性の樹脂等から形成されていて、その表面には、一対の導電部４３，４４が貼付されている。一対の導電部４３，４４は離間していて、互いに絶縁されている。また、基板４０の表面には、＋極用の信号用線材３１が導電部４３，４４に導通しないように配線されている。一方、−極用の信号用線材３２は分断されており、一方の端部３２ａが導通部４３に導通されていて、他方の端部３２ｂが導通部４４に導通されている。つまり、このままの状態であると−極用の信号用線材３２は絶縁された状態となっている。
基板４０の裏面には、貫通孔４２と連続する貫通孔４５を有する金属板４６が取り付けられている。この金属板４６にはワイヤ固定リング４７が重ねられており、金属板４６とワイヤ固定リング４７とで落下防止用ワイヤ３３の先端部を挟持している。また、前述したように、基板４０は絶縁性の樹脂等から形成されているため、基板４０の表面に配線された信号用線材３１，３２は家屋の壁や落下防止用ワイヤ３３から絶縁されることになる。 The base 38 includes a substrate 40 to which the signal wires 31 and 32 and the fall prevention wire 33 are fixed, a wall portion 41 standing from the periphery of the substrate 40, and a through hole 42 formed in the substrate 40. Is provided.
The substrate 40 is made of an insulating resin or the like, and a pair of conductive portions 43 and 44 are attached to the surface thereof. The pair of conductive portions 43 and 44 are separated from each other and insulated from each other. In addition, the positive electrode signal wire 31 is wired on the surface of the substrate 40 so as not to conduct to the conductive portions 43 and 44. On the other hand, the negative electrode signal wire 32 is divided, and one end portion 32 a is conducted to the conducting portion 43 and the other end portion 32 b is conducted to the conducting portion 44. That is, in this state, the negative electrode signal wire 32 is insulated.
A metal plate 46 having a through hole 45 continuous with the through hole 42 is attached to the back surface of the substrate 40. A wire fixing ring 47 is overlaid on the metal plate 46, and the metal plate 46 and the wire fixing ring 47 sandwich the tip of the fall prevention wire 33. Further, as described above, since the substrate 40 is formed of an insulating resin or the like, the signal wires 31 and 32 wired on the surface of the substrate 40 are insulated from the wall of the house and the fall prevention wire 33. It will be.

蓋部３９は開口４８を有していて、基台３８の壁部４１に取り付けられると開口４８により基台３８の貫通孔４２及び一対の導電部４３，４４を露出するようになっている。   The lid portion 39 has an opening 48. When the lid portion 39 is attached to the wall portion 41 of the base 38, the through hole 42 and the pair of conductive portions 43 and 44 of the base 38 are exposed through the opening 48.

固定部３７は、図２に示すように、開口４８に進入する固定片５１と、固定片５１に取り付けられ、貫通孔４２，４５を介して家屋等の壁に螺合するネジ５２とを備えている。   As shown in FIG. 2, the fixing portion 37 includes a fixing piece 51 that enters the opening 48, and a screw 52 that is attached to the fixing piece 51 and screwed into a wall of a house or the like through the through holes 42 and 45. ing.

図６は、固定片５１の概略構成を示す斜視図である。図６に示すように固定片５１には、ネジ５２が貫通する貫通孔５３と、貫通孔５３を挟んで対向する一対の導電層５４，５５が設けられている。この導電層５４，５５は、固定片５１が開口４８内に進入し、固定片５１の裏面と基板４０の表面とが接触すると、図４及び図５の点線Ｔに示す通り導電部４３，４４の両者に接触して、−極用の信号用線材３２を絶縁状態から導通状態に切り替えるようになっている。   FIG. 6 is a perspective view showing a schematic configuration of the fixed piece 51. As shown in FIG. 6, the fixing piece 51 is provided with a through-hole 53 through which the screw 52 passes and a pair of conductive layers 54 and 55 facing each other with the through-hole 53 interposed therebetween. When the fixed piece 51 enters the opening 48 and the back surface of the fixed piece 51 comes into contact with the front surface of the substrate 40, the conductive layers 54 and 55 are electrically conductive portions 43 and 44 as shown by the dotted line T in FIGS. The negative electrode signal wire 32 is switched from the insulated state to the conductive state.

次に、本実施形態の作用について説明する。
スピーカ１の設置時、スピーカ本体２とスピーカ用コード３とを接続する際には、ユーザはスピーカ用コード３の信号用線材３１，３２をスピーカ本体２の音声用端子２１，２２及びアンプに取り付け、落下防止用ワイヤ３３を落下防止用端子２３に取り付ける。
その後、ユーザは取付部３５を家屋等の壁に固定する。このとき、取付部３５の固定片５１の裏面が基板４０の表面に接触するまでネジ５２が締結されることで、導電部４３，４４と導電層５４，５５とが接触して、−極用の信号用線材３２が導通状態に切り替わる。これにより、スピーカ本体２と、アンプとが導通可能となる。 Next, the operation of this embodiment will be described.
When connecting the speaker body 2 and the speaker cord 3 when the speaker 1 is installed, the user attaches the signal wires 31 and 32 of the speaker cord 3 to the audio terminals 21 and 22 and the amplifier of the speaker body 2. Then, the fall prevention wire 33 is attached to the fall prevention terminal 23.
Thereafter, the user fixes the attachment portion 35 to a wall such as a house. At this time, the screws 52 are fastened until the back surface of the fixing piece 51 of the mounting portion 35 comes into contact with the surface of the substrate 40, so that the conductive portions 43 and 44 and the conductive layers 54 and 55 are in contact with each other. The signal wire 32 is switched to the conductive state. Thereby, the speaker main body 2 and the amplifier can be electrically connected.

以上のように、本実施形態によれば、信号用線材３１，３２と落下防止用ワイヤ３３とがカバー材３４によって一体的にまとめられているので、配線を簡素化することができ、見栄えがよくなる。さらに、スピーカ用コード３をスピーカ本体２に取り付けることで、信号用線材３１，３２と落下防止用ワイヤ３３とが確実にスピーカ本体２に取り付けられることになる。   As described above, according to the present embodiment, since the signal wires 31 and 32 and the fall prevention wire 33 are integrated together by the cover material 34, the wiring can be simplified and the appearance is improved. Get better. Furthermore, by attaching the speaker cord 3 to the speaker body 2, the signal wires 31 and 32 and the fall prevention wire 33 are securely attached to the speaker body 2.

さらに、固定部３７が、線材保持部３６を家屋等の壁に固定すると、信号用線材３２の絶縁状態を導通状態に切り替えるので、取付部３５を前記壁に取り付けなければ、スピーカ本体２とアンプとが導通しない状態のままとなる。つまり、スピーカ１を設置する際には取付部３５は必然的に壁に取り付けられることになるため、落下防止用ワイヤ３３も壁に固定され、落下防止機能が確実に発揮されることになる。   Furthermore, when the fixing part 37 fixes the wire holding part 36 to the wall of a house or the like, the insulation state of the signal wire 32 is switched to the conductive state. Therefore, if the attachment part 35 is not attached to the wall, the speaker body 2 and the amplifier And do not conduct. That is, when the speaker 1 is installed, the attachment portion 35 is inevitably attached to the wall, so that the fall prevention wire 33 is also fixed to the wall, and the fall prevention function is reliably exhibited.

なお、本発明は上記実施形態に限らず適宜変更可能であるのは勿論である。
例えば、本実施形態では、外部の構造体として家屋等の壁を例示して説明したが、車両等であってもよい。この場合、車両のトリム等に取付部を取り付けることになる。ここで、トリム等に取り付ける際には、図７に示すように取付部３５ａの金属板４６ａを下方が開放した断面視コ字状のものとして、その開放部分にトリム７０を挿入しネジ５２と金属板４６ａとで挟持するようにしている。なお、車両アース等を兼ねたトリムに取り付けられる場合であっても、基板４０によって信号用線材３１，３２がトリム７０や落下防止用ワイヤ３３から絶縁されているために、信号用線材３１，３２の絶縁性が確保されることになる。
また、上記実施形態では、−極用の信号用線材３２を分断し、絶縁状態と導電状態とを切り替える構成としたが、＋極用の信号用線材３１を分断して絶縁状態と導電状態とを切り替える構成としてもよいことは言うまでもない。 Of course, the present invention is not limited to the above-described embodiment and can be modified as appropriate.
For example, in the present embodiment, a wall such as a house is exemplified as an external structure, but a vehicle or the like may be used. In this case, the attachment portion is attached to the trim or the like of the vehicle. Here, when attaching to a trim or the like, as shown in FIG. 7, the metal plate 46a of the attachment portion 35a is formed in a U-shape in cross section with the lower part opened, and the trim 70 is inserted into the open part and the screw 52 and The metal plate 46a is sandwiched. Even when it is attached to a trim that also serves as a vehicle ground or the like, since the signal wires 31 and 32 are insulated from the trim 70 and the fall prevention wire 33 by the substrate 40, the signal wires 31 and 32 are used. Insulating properties are ensured.
Moreover, in the said embodiment, although it was set as the structure which divides | segments the signal wire | line 32 for negative electrodes, and switches an insulation state and a conductive state, it divides | segments the signal wire | line material 31 for + poles, and has an insulation state and a conductive state. Needless to say, the configuration may be changed.

また、上記実施形態では、固定片５１が−極用の信号用線材３２を絶縁状態から導電状態に切り替える場合を例示して説明したが、図８に示すように、ネジ５２によって−極用の信号用線材３２を絶縁状態から導電状態に切り替える構成であってもよい。この場合、導電部４３ａ，４３ｂが外部に露出していて、ネジ５２を締結した際、当該ネジ５２の頭部５２ａが点線部Ｔ１のように導電部４３ａ，４３ｂに接触して−極用の信号用線材３２を絶縁状態から導電状態に切り替えるようになっている。   In the above embodiment, the case where the fixing piece 51 switches the signal wire 32 for the negative electrode from the insulated state to the conductive state has been described as an example, but as shown in FIG. The signal wire 32 may be configured to be switched from an insulated state to a conductive state. In this case, when the conductive portions 43a and 43b are exposed to the outside and the screw 52 is fastened, the head 52a of the screw 52 comes into contact with the conductive portions 43a and 43b as indicated by the dotted line portion T1, and is used for the negative electrode. The signal wire 32 is switched from the insulated state to the conductive state.
