Description

本発明は、スピーカブロックとバスレフポートとを備えたバスレフ型スピーカユニットの前面を、複数の開口部を有する前面カバーにて覆った水廻りスピーカ構造及びこれを用いたスピーカ内蔵便器に関するものである。   The present invention relates to a water speaker structure in which a front surface of a bass reflex type speaker unit including a speaker block and a bass reflex port is covered with a front cover having a plurality of openings, and a toilet with a built-in speaker using the same.

近年、トイレ室にスピーカを設置して、流水音等の擬音を発生させたり、好みの音楽を楽しんだりすることが増えてきている（例えば、特許文献１参照）。   In recent years, a speaker is installed in a toilet room to generate a false sound such as running water and enjoy favorite music (for example, see Patent Document 1).

また、狭いスペースの設置に適したスピーカとして、小型で且つ低音再生が可能なバスレフ型スピーカユニットが好適に用いられている（例えば、特許文献２参照）。   Further, as a speaker suitable for installation in a narrow space, a bass reflex type speaker unit that is small and capable of reproducing a low sound is suitably used (for example, see Patent Document 2).

ところで、トイレ室内の清掃時には、ホースによる水かけ洗いや小水の飛散などが十分想定される。このため、浸水によるスピーカの故障を防ぐために前面カバーを取り付けるなどの防水対策が不可欠である。ただし一定の音質を確保するためには前面カバーに開口部を設ける必要があり、図７にその一例を示す。   By the way, at the time of cleaning the toilet room, water washing with a hose or scattering of small water is sufficiently assumed. For this reason, waterproofing measures such as attaching a front cover are indispensable in order to prevent the speaker from being damaged due to water immersion. However, in order to ensure a certain sound quality, it is necessary to provide an opening in the front cover, and an example is shown in FIG.

ところが図７に示すようなスリット構造の開口部５では、水の浸入が容易に起こり得る。また例えば、図８のように前面カバー４´及びスピーカユニット１´を傾けて水が浸入しにくくした場合でも、前面カバー４´にかかった水が開口部５に飛散して、図８の実線矢印→破線矢印で示すように、水の飛沫がバスレフポート（音響共鳴管）３内部を通じてスピーカブロック２内部に浸入するという課題がある。   However, in the opening portion 5 having the slit structure as shown in FIG. 7, water can easily enter. Further, for example, even when the front cover 4 ′ and the speaker unit 1 ′ are tilted as shown in FIG. 8 to make it difficult for water to enter, the water applied to the front cover 4 ′ scatters into the opening 5, and the solid line in FIG. As indicated by arrows → broken arrows, there is a problem that water splash enters the speaker block 2 through the bass reflex port (acoustic resonance tube) 3.

これを解決するためには、コーティングされた防水タイプのスピーカユニットを使用することも考えられるが、この場合、一般のコーティングされていないスピーカと比べて使用頻度が極端に低いこともあり、コストが高くつくという課題があり、さらにバスレフポート３は空気振動しているため防水構造にすることが困難であるという課題もある。
特開平８−２２８９６５号公報 特開平１１−４１６８０号公報 To solve this, it is conceivable to use a waterproof waterproof speaker unit that is coated. However, in this case, the frequency of use may be extremely low compared to a general uncoated speaker, and the cost is low. There is a problem that it is expensive, and there is also a problem that it is difficult to make a waterproof structure because the bass reflex port 3 vibrates with air.
JP-A-8-228965 Japanese Patent Laid-Open No. 11-41680

本発明は上記の従来の問題点に鑑みて発明したものであって、前面カバーの開口部からの水浸入を防止しつつ音質劣化を防ぐことができ、しかもコーティングされた防水タイプのスピーカを使用する必要がなく、低コストの水廻りスピーカ構造及びこれを用いたスピーカ内蔵便器を提供することを課題とするものである。   The present invention has been invented in view of the above-described conventional problems, and can prevent deterioration of sound quality while preventing water intrusion from the opening of the front cover, and uses a coated waterproof type speaker. Therefore, it is an object of the present invention to provide a low-cost water speaker structure and a speaker built-in toilet using the same.

前記課題を解決するために本発明の水廻りスピーカ構造は、スピーカブロック２とバスレフポート３とを備えたバスレフ型スピーカユニット１の前面を、複数の開口部５を有する前面カバー４にて覆った水廻りスピーカ構造であって、前面カバー４の開口部５は、スピーカブロック２の前方Ｈに位置するスピーカ側開口部６と、バスレフポート３の前方Ｈに位置するポート側開口部７とで構成され、スピーカ側開口部６を水浸入を防止しつつ高音域の音質劣化を防止し得る許容開口幅ｄにすると共に、ポート側開口部７の後端開口幅ｅをスピーカ側開口部６の許容開口幅ｄよりも狭くし且つポート側開口部７の少なくとも下面部８にその下面部前端８ａの高さが下面部後端８ｂよりも低くなるような前下がりの勾配Ｆを形成したことを特徴としている。   In order to solve the above problems, the water speaker structure of the present invention covers the front surface of the bass reflex type speaker unit 1 having the speaker block 2 and the bass reflex port 3 with the front cover 4 having a plurality of openings 5. In the water speaker structure, the opening 5 of the front cover 4 is composed of a speaker side opening 6 located in front H of the speaker block 2 and a port side opening 7 located in front H of the bass reflex port 3. In addition, the speaker-side opening 6 has an allowable opening width d that can prevent deterioration of the sound quality in the high sound range while preventing water from entering, and the rear-end opening width e of the port-side opening 7 is set to be allowable for the speaker-side opening 6. A front-falling gradient F is formed so as to be narrower than the opening width d and so that the height of the lower surface front end 8a is lower than the lower surface rear end 8b on at least the lower surface 8 of the port side opening 7. When To have.

このような構成とすることで、スピーカ側開口部６において水浸入を防止しつつスピーカブロック２から発せられる指向性の強い高周波成分の低下をなくすことができるようになり、一方、ポート側開口部７において、低周波を増長するバスレフポート３からの低音域の音質劣化を防止しつつ、水の飛沫を下面部８の前下がりの勾配Ｆに沿って外部に排水できるようになり、スピーカユニット１の故障の恐れを減じることができるようになる。   By adopting such a configuration, it is possible to eliminate a decrease in high-directivity high-frequency components emitted from the speaker block 2 while preventing water intrusion in the speaker-side opening 6, while the port-side opening 7, water droplets can be drained to the outside along the front-falling gradient F of the lower surface portion 8 while preventing deterioration of the sound quality in the bass range from the bass reflex port 3 that increases the low frequency. The risk of malfunctions can be reduced.

また、上記ポート側開口部７の前下がりの下面部８と対向する上面部９に、その上面部前端９ａの高さが上面部後端９ｂよりも高くなるような前上がりの勾配Ｇを形成するのが好ましく、この場合、ポート側開口部７において水の飛沫を外部に逃がす排水除去効果をより高めることができる。   Further, a forwardly rising gradient G is formed on the upper surface portion 9 facing the front lowering lower surface portion 8 of the port side opening 7 such that the height of the upper surface front end 9a is higher than that of the upper surface rear end 9b. In this case, it is possible to further enhance the drainage removal effect of escaping water splashes to the outside at the port side opening 7.

また、上記前面カバー４の上端縁４ａがその下端縁４ｂよりも前方Ｈに突出するように、前面カバー４全体を傾斜させるのが好ましく、この場合、水浸入防止効果をより高めながら、外観向上を図ることができる。   Further, it is preferable to incline the entire front cover 4 so that the upper end edge 4a of the front cover 4 protrudes forward H from the lower end edge 4b. In this case, the appearance is improved while further enhancing the water penetration preventing effect. Can be achieved.

さらに本発明の上記水廻りスピーカ構造を用いたスピーカ内蔵便器は、上記前面カバー４を樹脂製便器１０のスカート部１１に形成した穴部１２に取り付けると共に、スカート部１１の内側に前面カバー４に面してバスレフ型スピーカユニット１を設置したことを特徴としている。   Further, the toilet with built-in speaker using the above-mentioned water speaker structure according to the present invention attaches the front cover 4 to the hole portion 12 formed in the skirt portion 11 of the resin toilet 10, and attaches the front cover 4 to the inner side of the skirt portion 11. The bass reflex type speaker unit 1 is installed.

このような構成とすることで、樹脂製便器１０のスカート部１１内に、水浸入防止効果及び音質劣化防止効果に優れた前面カバー１４付きバスレフ型スピーカユニット１を一体化できるようになる。   With such a configuration, the bass reflex speaker unit 1 with the front cover 14 that is excellent in the effect of preventing water intrusion and the effect of preventing deterioration in sound quality can be integrated into the skirt portion 11 of the resin toilet 10.

本発明に係る水廻りスピーカ構造は、バスレフ型スピーカユニットの前面を覆う前面カバーの２種類の開口部（ポート側開口部、スピーカ側開口部）からの水浸入を防止しつつ音質劣化を防ぐことができるので、バスレフ型スピーカユニットの信頼性が向上すると共に、コーティングされた防水タイプのスピーカを使用する必要がなく、水廻りスピーカ構造の低コスト化を実現できるものである。   The water speaker structure according to the present invention prevents deterioration of sound quality while preventing water from entering from two types of openings (port side opening and speaker side opening) of the front cover that covers the front surface of the bass reflex type speaker unit. Therefore, the reliability of the bass-reflex type speaker unit is improved, and it is not necessary to use a coated waterproof type speaker, so that the cost of the water speaker structure can be reduced.

また本発明に係るスピーカ内蔵便器は、水浸入防止効果及び音質劣化防止効果に優れた水廻りスピーカ構造を樹脂製便器に対して容易に組み込むことができる。   Moreover, the toilet bowl with a built-in speaker according to the present invention can easily incorporate a water speaker structure excellent in an effect of preventing water intrusion and an effect of preventing deterioration of sound quality into a resin toilet bowl.

以下、本発明を添付図面に示す実施形態に基いて説明する。   Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

図１（ａ）（ｂ）は、本発明の一実施形態に用いるバスレフ型スピーカユニット１及び前面カバー４の一例を示し、図２は樹脂製便器１０の一例を示し、図３は該樹脂製便器１０のスカート部１１の内側にバスレフ型スピーカユニット１を収納する場合の一例を示す図である。   1A and 1B show an example of a bass-reflex speaker unit 1 and a front cover 4 used in an embodiment of the present invention, FIG. 2 shows an example of a resin toilet 10, and FIG. It is a figure which shows an example in the case of accommodating the bass-reflex type speaker unit 1 inside the skirt part 11 of the toilet bowl.

樹脂製便器１０は、ボウル部１３と、ボウル部１３の後部上面に付設された温水洗浄便座装置１４とを備えている。ボウル部１３の下端外周はスカート部１１で覆われている。   The resin toilet 10 includes a bowl portion 13 and a hot water cleaning toilet seat device 14 attached to the upper surface of the rear portion of the bowl portion 13. The outer periphery of the lower end of the bowl portion 13 is covered with a skirt portion 11.

上記スカート部１１の前面の左右両サイドには、一対のバスレフ型スピーカユニット１がそれぞれ内蔵されている。これらバスレフ型スピーカユニット１は、例えば、温水洗浄便座装置１４に設けた操作部（図示せず）にて操作され、操作の内容に応じて、好みの音楽や、水洗洗浄音の擬音、さらに音声による温水洗浄便座装置の使い方の説明などを適宜再生するものであり、より快適で便利なトイレ空間を提供できるようになっている。   A pair of bass reflex type speaker units 1 are respectively built in the left and right sides of the front surface of the skirt portion 11. These bass reflex type speaker units 1 are operated by, for example, an operation unit (not shown) provided in the warm water washing toilet seat device 14, and depending on the contents of the operation, favorite music, imitation of washing water washing sound, and voice The explanation of how to use the warm water washing toilet seat device is reproduced as appropriate, and more comfortable and convenient toilet space can be provided.

上記バスレフ型スピーカユニット１は、図１に示すように、スピーカブロック２と、低周波を増長するバスレフポート（音響共鳴管）３と、これらを収納するエンクロージャーと称される筐体１５とで構成されている。   As shown in FIG. 1, the bass reflex type speaker unit 1 includes a speaker block 2, a bass reflex port (acoustic resonance tube) 3 for increasing a low frequency, and a housing 15 called an enclosure for housing these. Has been.

本例では筐体１５の前面下部にスピーカブロック２が取り付けられ、その上部にポート部３が開口している。ここで、スピーカブロック２の背面に放射される音は前面に放射される音に対して位相が１８０°ずれているが、背面に放射される音が筐体１５内のバスレフポート３内を通じて前面から放射されるようになり、このときスピーカブロック２の前面から放射される音と位相が揃い、低音特性が増強されることで、バスレフポート３の前面部において低音再生域が拡大されるものである。なお本例では、スピーカブロック２の上にバスレフポート３を配置した例を示しているが、両者の位置関係はこれに限定されるものではなく、またスピーカブロック２とバスレフポート３の数も特に限定されるものではない。   In this example, the speaker block 2 is attached to the lower part of the front surface of the housing 15, and the port part 3 is opened above the speaker block 2. Here, the sound radiated to the back surface of the speaker block 2 is 180 degrees out of phase with the sound radiated to the front surface. However, the sound radiated to the back surface is transmitted through the bass reflex port 3 in the housing 15 to the front surface. At this time, the sound is radiated from the front of the speaker block 2 in phase with the sound, and the bass characteristic is enhanced, so that the bass reproduction area is expanded in the front part of the bass reflex port 3. is there. In this example, the bass reflex port 3 is arranged on the speaker block 2, but the positional relationship between the two is not limited to this, and the number of the speaker block 2 and the bass reflex port 3 is particularly limited. It is not limited.

上記バスレフ型スピーカユニット１の前面は前面カバー４にて覆われる。この前面カバー４は、樹脂製便器１０のスカート部１１に形成した穴部１２に取着されている。前面カバー４には、スピーカユニット１の発した音を前面カバー４の外部に通過させると共に水等の浸入を防止し得る複数の開口部５が穿設されている。この開口部５は、横方向に長く且つ上下に扁平なスリット構造を有しており、スピーカブロック２の前方Ｈに位置するスピーカ側開口部６と、バスレフポート３の前方Ｈに位置するポート側開口部７との２種類に分類されている。本例ではスピーカ側開口部６を水平スリットで構成し、ポート側開口部７を傾斜スリットで構成している。   The front surface of the bass reflex type speaker unit 1 is covered with a front cover 4. The front cover 4 is attached to a hole 12 formed in the skirt portion 11 of the resin toilet 10. The front cover 4 is provided with a plurality of openings 5 that allow the sound generated by the speaker unit 1 to pass outside the front cover 4 and prevent water and the like from entering. The opening 5 has a slit structure that is long in the horizontal direction and flat in the vertical direction. The opening 5 on the speaker side located at the front H of the speaker block 2 and the port side located at the front H of the bass reflex port 3. It is classified into two types, the opening 7. In this example, the speaker side opening 6 is constituted by a horizontal slit, and the port side opening 7 is constituted by an inclined slit.

ここで、上記スピーカブロック２の前方Ｈに位置するスピーカ側開口部６において、水浸入・異物侵入を防ぐ内部保護を想定した場合に、図４（ａ）のように最大許される上限値ｄを維持している。この上限値ｄがスピーカ側開口部６において水浸入を防止しつつ高音域の音質劣化を防止し得る許容開口幅となる。   Here, in the speaker-side opening 6 located in front H of the speaker block 2, when assuming internal protection to prevent water intrusion and entry of foreign matter, the maximum allowable upper limit value d as shown in FIG. Is maintained. This upper limit d is an allowable opening width that can prevent deterioration of sound quality in the high sound range while preventing water intrusion at the speaker-side opening 6.

一方、バスレフポート３の前方Ｈに位置するポート側開口部７において、水浸入・異物侵入を防ぐ内部保護を想定した場合に、スピーカ側開口部６と比べて開口形状のバスレフポート３では水の飛沫が浸入しやすいため、スピーカ側開口部６よりも狭める必要がある。そこで、本発明では、ポート側開口部７の後端開口幅ｅを前記スピーカ側開口部６の許容開口幅ｄよりも狭くし、且つ、ポート側開口部７の下面部８に、その下面部前端８ａの高さが下面部後端８ｂよりも低くなるような前下がりの勾配Ｆを形成している。これにより図５の矢印で示すように、水の飛沫を外部に逃がす排水除去効果が得られるようになっている。さらに本例では図４（ｃ）に示すように、ポート側開口部７の前下がりの下面部８と対向する上面部９に、その上面部前端９ａの高さが上面部後端９ｂよりも高くなるような前上がりの勾配Ｇを形成してある。これにより、ポート側開口部７はその後端から前端に行く程上下に幅広となり、前端開口幅ｆはスピーカ側開口部６の許容開口幅ｄとほぼ同じ程度となっている。これにより勾配Ｆ，Ｇによって水の飛沫を外部に跳ね返すことができると共に、バスレフポート３からの低音域の音質劣化を防止できるようになっている。つまり、バスレフポート３から発せられる音は主に低周波域で指向性が弱いため、ポート側開口部７の後端開口幅ｅをスピーカ側開口部６の許容開口幅ｄよりも狭くした場合でも、バスレフポート３からの低音域の音質劣化がないものである。   On the other hand, in the port side opening 7 located in front H of the bass reflex port 3, assuming internal protection to prevent water intrusion and entry of foreign matter, the bass reflex port 3 having an opening shape as compared with the speaker side opening 6 has water. Since it is easy for the splash to enter, it is necessary to make it narrower than the opening 6 on the speaker side. Therefore, in the present invention, the rear end opening width e of the port side opening 7 is made narrower than the allowable opening width d of the speaker side opening 6, and the lower surface portion of the port side opening 7 is provided on the lower surface portion thereof. A front-falling gradient F is formed such that the height of the front end 8a is lower than that of the lower surface rear end 8b. As a result, as shown by the arrows in FIG. 5, a drainage removing effect for escaping water splashes to the outside can be obtained. Further, in this example, as shown in FIG. 4 (c), the height of the upper surface front end 9a is higher than that of the upper surface rear end 9b on the upper surface portion 9 facing the front lower surface 8 of the port side opening 7. A rising slope G is formed so as to increase. As a result, the port-side opening 7 becomes wider in the vertical direction from the rear end to the front end, and the front-end opening width f is approximately the same as the allowable opening width d of the speaker-side opening 6. As a result, the splashes of water can be rebounded to the outside by the gradients F and G, and the sound quality deterioration in the low sound range from the bass reflex port 3 can be prevented. That is, the sound emitted from the bass reflex port 3 is weak in directivity mainly in the low frequency range, so even if the rear end opening width e of the port side opening 7 is narrower than the allowable opening width d of the speaker side opening 6. The sound quality in the bass range from the bass reflex port 3 is not deteriorated.

ちなみに、スピーカ側開口部６の許容開口幅ｄをポート側開口部７と同様に狭めると、スピーカブロック２から発せられる指向性の強い高周波成分が低下して音質が明確に劣化してしまうことになる。そこで、本発明では、スピーカ側開口部６では、図４（ａ）のように勾配をつけずに、水浸入及び高音域の劣化を防止し得る許容開口幅ｄで開口させるようにしている。   Incidentally, if the allowable opening width d of the speaker-side opening 6 is narrowed in the same manner as the port-side opening 7, the high directivity high-frequency component emitted from the speaker block 2 is reduced and the sound quality is clearly degraded. Become. Therefore, in the present invention, the speaker-side opening 6 is opened with an allowable opening width d that can prevent water intrusion and deterioration of the treble range without providing a gradient as shown in FIG.

しかして、上記構成のように、前面カバー４の開口部５をポート側開口部７とスピーカ側開口部６の２種類に分類することで、開口部５からの水の飛沫等の浸入防止を図ることができると共に、音の通過性への影響はほとんどなく、これにより、前面カバー４の前面方向から音の高音域および低音域を十分に聞き取ることができ、バスレフ型による音質向上を図ることが可能となる。しかも、前面カバー４の開口部５の開口幅等を設計変更をするだけで、コーティングされた防水タイプのスピーカを用いる必要がなくなり、安価な構成部品で、充分な防水対策を行うことができる。   As described above, the opening 5 of the front cover 4 is classified into two types, that is, the port-side opening 7 and the speaker-side opening 6, thereby preventing intrusion of water droplets and the like from the opening 5. In addition to being able to plan, there is almost no effect on the sound passage property, so that the high and low frequencies of the sound can be sufficiently heard from the front direction of the front cover 4 and the sound quality is improved by the bass reflex type. Is possible. Moreover, it is not necessary to use a coated waterproof type speaker by simply changing the design of the opening width of the opening 5 of the front cover 4, and sufficient waterproofing measures can be taken with inexpensive components.

また本例では樹脂製便器１０のスカート部１１にバスレフ型スピーカユニット１を組み込むことによって、既設の樹脂製便器１０に対して低コストで付加的に設置可能となる。   Further, in this example, by incorporating the bass reflex speaker unit 1 into the skirt portion 11 of the resin toilet 10, it can be additionally installed at low cost with respect to the existing resin toilet 10.

さらに本例ではポート側開口部７の後端開口幅ｅを狭くできるので、外部からポート側開口部７を通してバスレフポート３の開口形状が透視されにくくなり、外観が良好になる利点もある。   Furthermore, in this example, since the rear end opening width e of the port side opening 7 can be narrowed, the opening shape of the bass reflex port 3 is hardly seen from the outside through the port side opening 7, and there is an advantage that the appearance is improved.

なお、前記実施形態では、ポート側開口部７の上下両面に勾配Ｆ，Ｇを設けた場合を説明したが、他の実施形態として、水の飛散が上方からの飛散だけを想定した場合は、図６（ａ）に示すように、ポート側開口部７の下面部８のみに前下がりの勾配Ｆを形成した片側勾配のスリット構造としてもよい。この場合、水浸入防止効果をより高めることができる構造となり、さらに図６（ｂ）に示すように、前面カバー４の上端縁４ａが下端縁４ｂよりも前方Ｈに突出するように、前面カバー４全体を傾斜させると共に、この前面カバー４と同じ角度、同じ向きにバスレフ型スピーカユニット１全体を傾斜させるようにしてもよく、これにより音質の劣化を更に軽減しつつ、前面カバー４による水浸入防止効果、外観向上効果をより一層高めることができる。   In the above-described embodiment, the case where the gradients F and G are provided on the upper and lower surfaces of the port-side opening 7 has been described. However, as another embodiment, when the scattering of water is assumed to be only scattering from above, As shown in FIG. 6A, a slit structure with a one-sided gradient in which a gradient F with a downward slope is formed only on the lower surface portion 8 of the port-side opening 7 may be used. In this case, the front cover is structured such that the effect of preventing water intrusion can be further enhanced, and further, as shown in FIG. 6B, the upper end edge 4a of the front cover 4 protrudes forward H from the lower end edge 4b. The entire bass reflex speaker unit 1 may be tilted at the same angle and in the same direction as the front cover 4, thereby further reducing the deterioration of sound quality and allowing water to enter the front cover 4. The prevention effect and the appearance improvement effect can be further enhanced.

本発明の水廻りスピーカ構造は、樹脂製便器に適用されるだけでなく、トイレ室内の水廻り、さらにトイレ室以外の住宅設備の水廻りに広範囲に適用可能である。   The water speaker structure of the present invention is not only applied to a resin toilet, but can be applied to a wide range of water in a toilet room and further in a housing facility other than a toilet room.
