Description

照明器具付きスピーカSpeaker with lighting equipment
　本発明は、スピーカに関し、特に照明器具を備えたものに関する。 The present invention relates to a speaker, and more particularly to a speaker equipped with a lighting fixture.
　スピーカには、例えば特許文献１に開示されているような天井内に埋め込まれる天井スピーカがある。また、天井に埋め込まれる照明器具として、例えば特許文献２に開示されているようなダウンライトがある。 There is a ceiling speaker embedded in the ceiling as disclosed in Patent Document 1, for example. Moreover, as a lighting fixture embedded in the ceiling, there is a downlight as disclosed in Patent Document 2, for example.
特許第３４６７３２６号Japanese Patent No. 3467326 特開２００８－１６４１７号JP 2008-16417 A
　インテリア照明としてダウンライトを複数配置しているような場所で、例えばバックグランドミュージックを流すことがある。このような場合、複数のダウンライトの中に天井スピーカを配置すると、ダウンライトと天井スピーカの天井面に露出している形状が異なるので、空間の意匠性が損なわれる。そこで、ダウンライトに似た外観を持つ天井スピーカ、例えばダウンライトの筐体内に、ライトに代えてスピーカユニットを設けたものを配置することも考えられる。しかし、このスピーカでは、音しか出ないので、このスピーカの近傍にいる人に故障したダウンライトと勘違いされたり、スピーカの近傍だけ空間の明るさが弱いと感じられたりして、人に違和感を与える可能性がある。このようなことはダウンライトだけでなく、天井付近に他の照明器具、例えばスポットライトを複数設けた状態において、この照明器具の筐体を利用してスピーカを設置すれば生じ得る。このように、天井に照明器具とスピーカとを混在させる空間では、意匠性はもちろん、近傍にいる人に与える違和感が問題となる。 For example, background music may be played in a place where multiple downlights are arranged as interior lighting. In such a case, when a ceiling speaker is arranged in a plurality of downlights, the shape exposed on the ceiling surface of the downlight and the ceiling speaker is different, so that the design of the space is impaired. Therefore, it is also conceivable to arrange a ceiling speaker having an appearance similar to that of a downlight, for example, a speaker provided with a speaker unit in place of the light in the casing of the downlight. However, since this speaker only produces sound, it can be mistaken for a downlight by a person in the vicinity of this speaker, or it can be felt that the brightness of the space is weak only in the vicinity of the speaker. There is a possibility to give. Such a situation may occur when a speaker is installed using the casing of the lighting fixture in a state where a plurality of other lighting fixtures, for example, spotlights, are provided in the vicinity of the ceiling in addition to the downlight. In this way, in a space where a lighting fixture and a speaker are mixed on the ceiling, not only design properties but also a sense of discomfort given to people in the vicinity becomes a problem.
　本発明は、天井またはその付近に設置される照明器具と共に使用しても、空間の意匠性を損なわず、近傍にいる人に違和感を与えることのない照明付きスピーカを提供することを目的とする。 An object of the present invention is to provide an illuminated speaker that does not impair the design of a space and does not give a sense of incongruity to people in the vicinity even when used with a lighting fixture installed on or near the ceiling. .
　本発明の一態様の照明付きスピーカは、収容部を有している。収容部は、開口部を備え、この開口部に連なる内部が中空のものである。収容部としては、例えば円筒状、角筒状のものや、椀状のものを使用することができ、例えば天井内に埋め込むものや天井付近に設置するものとすることができる。この収容部の内部にスピーカユニットが設けられている。このスピーカユニットは、前記開口部側に向けて放音するように、放音部が前記開口部側に位置する。前記スピーカユニットの近傍に位置するように前記収容部内に光源が設けられている。光源として１つの光源を設けることもできるし、複数の光源を設けることもできる。光源としては、ＬＥＤ、電球、蛍光灯等を使用することができる。前記収容部内における前記スピーカと前記開口部との間に通過部が設けられている。この通過部は、前記スピーカユニットの放音部から放音される音と、前記光源から放射される光とを、前記開口部側に向けて通過させる。 The illuminated speaker of one embodiment of the present invention has a housing portion. The accommodating portion includes an opening, and the inside connected to the opening is hollow. As the accommodating portion, for example, a cylindrical shape, a rectangular tube shape, or a bowl shape can be used. For example, it can be embedded in the ceiling or installed near the ceiling. A speaker unit is provided inside the housing portion. In this speaker unit, the sound emitting part is positioned on the opening side so that sound is emitted toward the opening side. A light source is provided in the housing portion so as to be positioned in the vicinity of the speaker unit. One light source can be provided as the light source, or a plurality of light sources can be provided. As the light source, an LED, a light bulb, a fluorescent lamp, or the like can be used. A passage portion is provided between the speaker and the opening in the housing portion. The passage portion allows the sound emitted from the sound emission portion of the speaker unit and the light emitted from the light source to pass toward the opening.
　このように構成された照明付きスピーカでは、スピーカからの音を、通過部を介して収容部の開口部から外部に放音することができる。さらに、光源からの光も通過部を介して収容部の開口部から放射され、外部を照明する。収容部の外観を、ダウンライトやスポットライトのような天井内または天井付近に配置されている照明器具と類似の形状とすることによって、空間の意匠性を損なうことがなく、また、照明器具と似て照明機能を発揮するため、近傍にいる人に違和感を与えない。 In the illuminated speaker configured as described above, sound from the speaker can be emitted to the outside from the opening of the housing portion through the passage portion. Furthermore, the light from the light source is also emitted from the opening of the housing through the passage and illuminates the outside. By making the appearance of the housing part similar to a lighting fixture arranged in or near the ceiling, such as a downlight or a spotlight, the design of the space is not impaired, and the lighting fixture Since the lighting function is demonstrated in the same way, it does not give a sense of incongruity to people in the vicinity.
　前記光源を、前記スピーカユニットの周囲に設けることができる。この場合、光源は１つだけ設けることもできるし、複数の光源を設けることもできる。１つの光源を使用する場合には、環状の光源をスピーカの周囲に配置することができる。複数の光源を使用する場合には、スピーカの周囲を包囲するように複数の光源を配置することができる。前記通過部は、前記スピーカの放音部の周囲と前記開口部との間に配置される。通過部としては、スピーカの放音部の周囲に、スピーカからの音声を通過させる開口を有するものを使用する。この場合、通過部は、光を透過させる材質、例えば半透明や透明な樹脂で全体が構成されたものとすることもできるし、非透過性の材質のもの、例えば金属にメッシュを構成したものとすることもできる。このように構成すると、スピーカからの音は、通過部の開口から収容部の開口部を介して外部に放音することができる。さらに、スピーカユニットの周囲にある光源からの光が通過部を介して収容部の開口部から放射され、外部を照明する。 The light source can be provided around the speaker unit. In this case, only one light source can be provided, or a plurality of light sources can be provided. When one light source is used, an annular light source can be arranged around the speaker. When a plurality of light sources are used, the plurality of light sources can be arranged so as to surround the speaker. The passage portion is disposed between the periphery of the sound emitting portion of the speaker and the opening portion. As the passage portion, a passage portion having an opening through which sound from the speaker is passed is used around the sound emitting portion of the speaker. In this case, the passage part may be made of a material that transmits light, for example, a translucent or transparent resin, or a non-transparent material, for example, a metal mesh. It can also be. If comprised in this way, the sound from a speaker can be emitted outside through the opening part of an accommodating part from the opening of a passage part. Furthermore, the light from the light source around the speaker unit is emitted from the opening of the housing through the passage and illuminates the outside.
　前記収容部には、内外に貫通する放熱孔を設けることができる。このように構成することによって、光源が発生する熱を収容部の外部に効果的に排出することができ、スピーカユニットの特性に熱が悪影響を与えることを防止できる。 The housing part may be provided with a heat radiating hole penetrating in and out. With this configuration, the heat generated by the light source can be effectively discharged to the outside of the housing portion, and it is possible to prevent the heat from adversely affecting the characteristics of the speaker unit.
　前記通過部よりも奥の前記収容部内に、前記光源からの光を反射させるための反射手段を設けることもできる。このように反射手段を設けることによって、光源よりも収容部の奥に放射された光を反射して、通過部を介して収容部の開口部から放射することができ、効率的に照明することができる。 Reflecting means for reflecting the light from the light source may be provided in the housing part behind the passage part. By providing the reflecting means in this way, the light radiated to the back of the housing part can be reflected from the light source, and can be radiated from the opening of the housing part through the passage part. Can do.
　また、前記光源を、前記スピーカユニットの放音部の前方に配置することができる。この場合、前記通過部は、前記光源の周囲と前記収容部の開口部との間に配置されている。光源を放音部の前方に配置することで、より明度の高い照明器具付きスピーカを提供できる。 Further, the light source can be arranged in front of the sound emission part of the speaker unit. In this case, the passage portion is disposed between the periphery of the light source and the opening portion of the housing portion. By arranging the light source in front of the sound emitting unit, it is possible to provide a speaker with a lighting fixture having higher brightness.
　前記通過部は、前記光源の周囲から前記開口部に至るまでの所定の地点に設けられた折り返し点までは、もっぱら前記放音部から放音される音を通過させる第１通過部分と、折り返し点から折り返されて前記開口部に至るまでは、前記音と前記光源から放射される光とを通過させる第２通過部分とを、有するものとできる。このように構成すると、スピーカユニットからの音は、第１通過部分を介して、第２通過部分に到達し、第２通過部分によって拡散することを防止されて、収容部の開口部から外部に伝搬される。また、光源からの光は第２通過部分によって拡散することを防止されて、収容部の開口部から外部に放射される。 The passing portion is a first passing portion that allows the sound emitted from the sound emitting portion to pass through to the turning point provided at a predetermined point from the periphery of the light source to the opening, and the turning portion. From the point until it reaches the opening, it can have a second passage portion that allows the sound and the light emitted from the light source to pass therethrough. With this configuration, the sound from the speaker unit reaches the second passage portion through the first passage portion and is prevented from diffusing by the second passage portion, and is transmitted to the outside from the opening of the housing portion. Propagated. Further, the light from the light source is prevented from diffusing by the second passage portion, and is emitted to the outside from the opening of the housing portion.
　更に、前記第２通過部分に反射手段を設けることもできる。これによって、光源からの光は更に拡散することが防止されて、収容部の開口部から外部に放射され、明度を高めることができる。 Furthermore, a reflecting means can be provided in the second passage part. Accordingly, the light from the light source is prevented from further diffusing, and is emitted to the outside from the opening of the housing portion, so that the brightness can be increased.
　前記光源は、前記通過部が有する支持部に支持されているものとすることができる。この場合、支持部は、筒状に形成され、その内面に前記光源が配置され、前記支持部の内面に、前記光源からの光を反射させるための反射手段が設けられている。このように構成すると、光源からの光のうち支持部の内面に向かった光は、反射手段によって反射され、収容部の開口部に向かい、外部に放射される。従って、効率的に照明することができる。 The light source may be supported by a support part included in the passage part. In this case, the support portion is formed in a cylindrical shape, the light source is disposed on the inner surface thereof, and reflection means for reflecting light from the light source is provided on the inner surface of the support portion. If comprised in this way, the light which went to the inner surface of a support part among the lights from a light source will be reflected by a reflection means, will go to the opening part of an accommodating part, and will be radiated | emitted outside. Therefore, it can illuminate efficiently.
　前記スピーカユニットを、コーンスピーカユニットとすることができる。この場合、前記コーンスピーカユニットの鳴動時の振動によって生じる前記コーンスピーカユニットのコーンの最大振幅よりも長い距離を隔てて前記コーンスピーカユニットの放音部と前記光源とが位置している。このように構成すると、コーンスピーカユニットを最大の入力音で鳴動させたときでもコーンが光源にぶつかることを防ぐことができ、音を適切に開口部まで通過させることができる The speaker unit can be a cone speaker unit. In this case, the sound emission part of the cone speaker unit and the light source are located at a distance longer than the maximum amplitude of the cone of the cone speaker unit caused by vibration when the cone speaker unit rings. With this configuration, the cone can be prevented from hitting the light source even when the cone speaker unit is ringed with the maximum input sound, and the sound can be appropriately passed to the opening.
　光源をＬＥＤとすることもできる。このように構成することにより、光源を小型化することができ、スピーカと光源とを収容部内に容易に配置することができ、収容部を、ダウンライトやスポットライトの外部形状とほぼ同じ大きさにすることが可能となり、空間の意匠性をより確実に保つことができる。また、ＬＥＤは光源となる他の照明部材よりも発熱量が小さいため、光源から発せられる熱がスピーカユニットの特性に悪影響を与えることを抑えることができる。 The light source can be an LED. With this configuration, the light source can be reduced in size, the speaker and the light source can be easily disposed in the housing, and the housing is approximately the same size as the external shape of the downlight or spotlight. And the design of the space can be more reliably maintained. Further, since the LED generates a smaller amount of heat than other illumination members that serve as the light source, it is possible to suppress the heat generated from the light source from adversely affecting the characteristics of the speaker unit.
　以上のように、本発明による照明器具付きのスピーカによれば、天井またはその付近に設置される照明器具と共に使用しても、空間の意匠性を損なうことがない。 As described above, according to the speaker with a lighting fixture according to the present invention, the design of the space is not impaired even when used with a lighting fixture installed on or near the ceiling.

　本発明の第１実施形態の照明器具付きスピーカは、例えば商業施設において、複数のダウンライトが取り付けられているような場所に使用されるもので、図１に示すように、収容部２を有している。収容部２は、筒状体、例えば円筒状の周壁部４を有し、その一方の端部が開口部６とされ、他方の端部が内奥壁８によって閉じられている。開口部６の周縁には環状フランジ１０が形成されている。この収容部２は、例えば天井１２に形成された孔内に、開口部６が天井１２の表面側に位置し、フランジ１０が天井１２の表面に接するように、孔内に取り付けられている。この取り付けられた状態において、収容部２が、同じ天井１２に取り付けられているダウンライトと同じに見えるように、開口部６の形状や寸法は、選択されている。 The speaker with a lighting apparatus according to the first embodiment of the present invention is used in a place where a plurality of downlights are attached, for example, in a commercial facility. As shown in FIG. is doing. The accommodating part 2 has a cylindrical body, for example, a cylindrical peripheral wall part 4, one end of which is an opening 6, and the other end is closed by an inner back wall 8. An annular flange 10 is formed on the periphery of the opening 6. The accommodating portion 2 is attached in the hole, for example, in a hole formed in the ceiling 12 so that the opening 6 is located on the surface side of the ceiling 12 and the flange 10 is in contact with the surface of the ceiling 12. In this attached state, the shape and dimensions of the opening 6 are selected so that the accommodating portion 2 looks the same as the downlight attached to the same ceiling 12.
　この収容部２内の中心軸線上の内奥壁８側によった位置に、コーンスピーカユニット１４が配置されている。コーンスピーカユニット１４は、本発明のスピーカユニットの一例である。コーンスピーカユニット１４は、その放音部、例えばコーンスピーカユニット１４のコーンの先端にある放音開口１６が、開口部６側を向くように収容部２内に取り付けられている。 The cone speaker unit 14 is arranged at a position on the inner back wall 8 side on the central axis in the housing portion 2. The cone speaker unit 14 is an example of the speaker unit of the present invention. The cone speaker unit 14 is mounted in the accommodating portion 2 such that a sound emitting portion, for example, a sound emitting opening 16 at the tip of the cone of the cone speaker unit 14 faces the opening 6 side.
　収容部２の周壁部４の内面及び内奥壁８の内面には、反射手段、例えば反射膜１８ａ、１８ｂが取り付けられている。この周壁部４の反射膜１８ａ上に、コーンスピーカユニット１４を包囲するように、複数の光源、例えばＬＥＤ２０が取り付けられている。これらＬＥＤ２０は、反射膜１８ａ上に取り付けた環状の帯状体１９上に、その周方向に所定の間隔をそれぞれあけて配置されている。各ＬＥＤ２０は、発光面２１を有し、この発光面２１と反対側の面が帯状体１９に取り付けられている。実際には、帯状体１９上に各ＬＥＤ２０を取り付けた後、帯状体１９を環状にして、反射膜１８ａ上に取り付ける。これによって、発光面２１が、コーンスピーカユニット１４側を向いている。各ＬＥＤ２０は、取り付けられた状態において、発光面２１から開口部６側に向かう光、コーンスピーカユニット１４側及び内奥壁８側に向かう光を放射するように構成されている。このコーンスピーカユニット１４方向及び内奥壁８側に放射された光は、図に示すように反射膜１８ａ、１８ｂによって反射されて、開口部６に向かう。このように、直接に開口部６側に放射される光以外の光も反射させて、開口部６から放射するので、開口部６から均一に光を放射することができる。 Reflecting means, for example, reflecting films 18 a and 18 b are attached to the inner surface of the peripheral wall portion 4 and the inner inner wall 8 of the housing portion 2. A plurality of light sources, for example, LEDs 20 are attached on the reflective film 18 a of the peripheral wall 4 so as to surround the cone speaker unit 14. These LEDs 20 are arranged on the annular strip 19 attached on the reflective film 18a at predetermined intervals in the circumferential direction. Each LED 20 has a light emitting surface 21, and a surface opposite to the light emitting surface 21 is attached to the belt 19. Actually, after each LED 20 is mounted on the strip-shaped body 19, the strip-shaped body 19 is formed into a ring shape and mounted on the reflective film 18a. As a result, the light emitting surface 21 faces the cone speaker unit 14 side. Each LED 20 is configured to emit light from the light emitting surface 21 toward the opening 6 and light toward the cone speaker unit 14 and the inner back wall 8 in the attached state. The light radiated in the direction of the cone speaker unit 14 and the inner back wall 8 is reflected by the reflection films 18 a and 18 b toward the opening 6 as shown in the figure. Thus, since light other than the light radiated directly to the opening 6 side is also reflected and emitted from the opening 6, the light can be emitted uniformly from the opening 6.
　これらＬＥＤ２０よりも開口部６側によった位置に、通過部、例えば光透過部２２が設けられている。具体的には、光透過部２２は、コーンスピーカユニット１４の放音開口１６の周縁に、放音開口１６の周縁にほぼ一致する開口２３を有し、この開口２３から、開口部６の周縁まで伸延し、開口部６側の面がパラボラ反射鏡状に湾曲させて形成されている。この構成により、光透過部２２が、コーンスピーカユニット１４の放音開口１６から発せられる音の伝搬を助ける音道としても機能し、コーンスピーカユニット１４からの音は良好に開口部６から外部に伝搬する。光透過部２２は、例えば半透明材料によって構成されている。従って、ＬＥＤ２０からの直接の光や、反射膜１８ａ、１８ｂによって反射された光は、この半透明の光透過部２２を透過して、柔らかい光となって、開口部６から放射される。また、光透過部２２を透過した光には、直接に開口部６から放射されるものの他に、図に符号Ａで示すように光透過部２２を透過した後に、この透過した位置とは別の位置の光透過部２２の表面で一部が反射されて、開口部６から放射されるものがある。一般のダウンライトにおいても、反射部を設けて光を反射させているので、開口部６からの光は、通常のダウンライトからの光と同様になる。 A passage part, for example, a light transmission part 22 is provided at a position closer to the opening part 6 than these LEDs 20. Specifically, the light transmission part 22 has an opening 23 that substantially coincides with the periphery of the sound emission opening 16 at the periphery of the sound emission opening 16 of the cone speaker unit 14. The surface on the side of the opening 6 is curved in a parabolic reflector shape. With this configuration, the light transmitting portion 22 also functions as a sound path that assists the propagation of the sound emitted from the sound emission opening 16 of the cone speaker unit 14, and the sound from the cone speaker unit 14 is satisfactorily transmitted from the opening 6 to the outside. Propagate. The light transmission portion 22 is made of, for example, a translucent material. Therefore, the direct light from the LED 20 and the light reflected by the reflection films 18 a and 18 b are transmitted through the translucent light transmission part 22 and become soft light and are emitted from the opening 6. In addition to the light directly radiated from the opening 6, the light transmitted through the light transmission part 22 is transmitted through the light transmission part 22 as indicated by a symbol A in FIG. Some of the light is reflected from the surface of the light transmitting portion 22 at the position and is emitted from the opening 6. Even in a general downlight, since the light is reflected by providing the reflecting portion, the light from the opening 6 is the same as the light from the normal downlight.
　また、内奥壁８の周縁部には、ＬＥＤ２０が発生する熱を、外部に排出するための複数の放熱孔２４が内外を貫通するように設けられている。放熱孔２４としては円孔とすることもできるし、長孔とすることもできる。 Further, a plurality of heat radiation holes 24 for exhausting heat generated by the LEDs 20 to the outside are provided in the peripheral portion of the inner back wall 8 so as to penetrate inside and outside. The heat dissipation hole 24 can be a circular hole or a long hole.
　このように構成された照明付きスピーカでは、天井に埋め込まれた収容部２の開口部６から音が放出されると共に、開口部６からダウンライトと同様に光が放射されるので、他にダウンライトが使用されているような状況で使用しても、空間の意匠性を損なうことがなく、また、ダウンライトと似た照明機能を発揮するため、このスピーカの近傍にいる人に違和感を与えることがない。特に、光透過部２２を使用しているので、ＬＥＤ２０は、コーンスピーカユニット１４の周囲に配置することができ、通常のダウンライトと同じような大きさの収容部２を使用しても、光源としてのＬＥＤ２０とコーンスピーカユニット１４とを無理なく収容することができる。また、放熱孔２４を設けてあるので、ＬＥＤ２０が発生する熱は放熱孔２４から天井１２内に効果的に排出され、コーンスピーカユニット１４の特性が、ＬＥＤ２０の発熱の影響を受けにくくなる。 In the illuminated speaker configured as described above, sound is emitted from the opening 6 of the housing 2 embedded in the ceiling, and light is emitted from the opening 6 in the same manner as the downlight. Even if it is used in a situation where a light is used, it will not impair the design of the space, and it will exhibit a lighting function similar to that of a downlight, giving a sense of discomfort to people in the vicinity of this speaker There is nothing. In particular, since the light transmitting portion 22 is used, the LED 20 can be disposed around the cone speaker unit 14, and even if the accommodating portion 2 having the same size as a normal downlight is used, the light source The LED 20 and the cone speaker unit 14 can be accommodated without difficulty. Further, since the heat radiating hole 24 is provided, the heat generated by the LED 20 is effectively discharged from the heat radiating hole 24 into the ceiling 12, and the characteristics of the cone speaker unit 14 are less affected by the heat generated by the LED 20.
　本発明の第２実施形態の照明器具付きスピーカを図２及び図３に示す。第２実施形態の照明器具付きスピーカも、第１実施形態の照明器具付きスピーカと同様な収容部１０２を備えている。収容部１０２は、筒状体、例えば円筒状の周壁部１０４と、開口部１０６と、内奥壁１０８と、環状フランジ１１０とを有している。この収容部１０２も、例えば天井に形成された孔内に、第１実施形態の収容部１０２と同様に取り付けられ、この取り付けられた状態において、収容部１０２が、同じ天井に取り付けられているダウンライトと同じに見えるように、開口部１０６の形状や寸法が、選択されている。 2 and 3 show a speaker with a lighting fixture according to a second embodiment of the present invention. The speaker with the luminaire of the second embodiment also includes a housing portion 102 similar to the speaker with the luminaire of the first embodiment. The accommodating part 102 has a cylindrical body, for example, a cylindrical peripheral wall part 104, an opening part 106, an inner back wall 108, and an annular flange 110. The housing portion 102 is also attached to, for example, a hole formed in the ceiling in the same manner as the housing portion 102 of the first embodiment. In this attached state, the housing portion 102 is attached to the same ceiling. The shape and size of the opening 106 is selected so that it looks the same as the light.
　この収容部１０２内の中心軸線上の内奥壁１０８側によった位置に、スピーカユニット、例えばコーンスピーカユニット１１４が配置されている。コーンスピーカユニット１１４は、その放音部、例えばコーンスピーカユニット１４のコーンの先端にある放音開口１１６が、開口部１０６側を向くように収容部１０２内に取り付けられている。この取り付け状態において、コーンスピーカユニット１１４は、その外周縁部が周壁部１０４に接するように取り付けられている。 A speaker unit, for example, a cone speaker unit 114 is disposed at a position on the inner back wall 108 side on the central axis in the housing portion 102. The cone speaker unit 114 is mounted in the accommodating portion 102 so that a sound emitting portion thereof, for example, a sound emitting opening 116 at the tip of the cone of the cone speaker unit 14 faces the opening portion 106 side. In this attached state, the cone speaker unit 114 is attached such that the outer peripheral edge thereof is in contact with the peripheral wall 104.
　このコーンスピーカユニット１１４の前方の収容部１０２内に、収容部１０２の中心軸線上に位置するように支持部１３０が設けられている。支持部１３０は、コーンスピーカユニット１１４よりもかなり小さい筒状、例えば円筒状に形成され、それの開口部１０６側の端部１３２が開口したものである。支持部１３０の内面全域に反射手段、例えば反射膜１３４が形成されている。 A support portion 130 is provided in the accommodating portion 102 in front of the cone speaker unit 114 so as to be positioned on the central axis of the accommodating portion 102. The support portion 130 is formed in a cylindrical shape that is considerably smaller than the cone speaker unit 114, for example, a cylindrical shape, and an end portion 132 on the opening portion 106 side thereof is opened. Reflecting means, for example, a reflective film 134 is formed on the entire inner surface of the support portion 130.
　この支持部１３０の内奥壁にソケット１３６が取り付けられ、このソケット１３６に光源、例えばＬＥＤ１２０が取り付けられている。ＬＥＤ１２０は電球型のもので、支持部１３０の端部１３２から光を開口部１０６側に放射するものである。また、ＬＥＤ１２０からの光は、反射膜１３４側にも放射され、反射膜１３４で反射された光も、支持部１３２の端部１３３から開口部１０６側に放射される。なお、符号１３８で示すのは、ソケット１３６の端子で、これは図示していないリード線を介して収容部１０２の外部に設けられた電源部（図示せず）に接続されている。 A socket 136 is attached to the inner back wall of the support portion 130, and a light source, for example, an LED 120 is attached to the socket 136. The LED 120 is of a light bulb type, and emits light from the end portion 132 of the support portion 130 toward the opening portion 106 side. The light from the LED 120 is also emitted to the reflective film 134 side, and the light reflected by the reflective film 134 is also emitted from the end 133 of the support part 132 to the opening 106 side. Reference numeral 138 denotes a terminal of the socket 136, which is connected to a power supply unit (not shown) provided outside the housing unit 102 via a lead wire (not shown).
　支持部１３０の外周から収容部１０２の開口部１０６にわたって通過部１３０が配置されている。通過部１３０は、支持部１３０の外周から収容部１０２の内周面の近傍の折り返し点１４０まで、コーンスピーカユニット１１４の放音開口１１６と略平行に延伸している第１通過部分１４２を有し、折り返し点１４０で折り返されて、開口部１０６にかけて延伸する第２通過部分１４４を有している。 The passage part 130 is arranged from the outer periphery of the support part 130 to the opening part 106 of the accommodating part 102. The passage portion 130 has a first passage portion 142 extending from the outer periphery of the support portion 130 to the turning point 140 in the vicinity of the inner peripheral surface of the housing portion 102 and extending substantially parallel to the sound emission opening 116 of the cone speaker unit 114. The second passage portion 144 is folded at the folding point 140 and extends toward the opening 106.
　第１通過部分１４２には、図３に示すように複数の支持腕１４６が、互いに間隔をあけて、例えば等しい間隔をあけて、支持部１３２と一体に設けられ、支持部３２を支持している。これら支持腕１４６は、直線状に収容部１０２の内面側に向かって折り返し点１４０まで伸びている。各支持腕１４６の間の空間には、図２に示すように音を通過させるためのメッシュ１４８が設けられている。なお、図３では、メッシュ１４８を省略してある。第１通過部分１４２において、各支持腕１４６の間の空間をメッシュ１４８を介してコーンスピーカユニット１１４から拡声された音声が通過して、開口部１０６から外部に伝搬する。なお、支持部１３０の内奥の外面は、コーンスピーカユニット１１４が備えるコーンの最大振幅（図２に破線で示す）の頂点位置よりもコーンスピーカユニット１１４から離れた位置に位置している。つまり、支持部１３０とコーンスピーカユニット１１４とは図２中の矢印で示す距離よりも離間して配置されている。なお、コーンの最大振幅とは、許容される最大の音声信号が入力されて鳴動する際に振動するコーンの振動幅である。 As shown in FIG. 3, a plurality of support arms 146 are provided in the first passage portion 142 at an interval, for example, at an equal interval, and are integrally provided with the support portion 132 to support the support portion 32. Yes. These support arms 146 extend linearly toward the inner surface side of the accommodating portion 102 to the turning point 140. In the space between the support arms 146, a mesh 148 for passing sound is provided as shown in FIG. In FIG. 3, the mesh 148 is omitted. In the first passage portion 142, the sound amplified from the cone speaker unit 114 passes through the space between the support arms 146 via the mesh 148 and propagates to the outside from the opening 106. The outer surface of the inner part of the support portion 130 is located at a position farther from the cone speaker unit 114 than the apex position of the maximum cone amplitude (shown by a broken line in FIG. 2) of the cone speaker unit 114. That is, the support part 130 and the cone speaker unit 114 are arranged apart from the distance indicated by the arrow in FIG. Note that the maximum amplitude of the cone is the vibration width of the cone that vibrates when the maximum allowable audio signal is input and sounded.
