Description

この発明は無線機器に係わり、特に、そのマイクロホンの防水構造に関する。   The present invention relates to a wireless device, and more particularly to a waterproof structure of the microphone.

従来の携帯電話機等の無線機器内部に配置されるマイクロホンの防水構造の例を図５に示す。図５に示すフロントケース１には音通過孔１ａが設けられ音通過孔１ａの内部にコンデンサマイクロホン２（ＥＣＭ）が配置されている。フロントケース１とコンデンサマイクロホン２の間にはゴム製のパッキング８が介装されている。   FIG. 5 shows an example of a waterproof structure of a microphone disposed inside a wireless device such as a conventional mobile phone. The front case 1 shown in FIG. 5 is provided with a sound passage hole 1a, and a condenser microphone 2 (ECM) is disposed inside the sound passage hole 1a. A rubber packing 8 is interposed between the front case 1 and the condenser microphone 2.

パッキング８に設けられたループ状のリブ８ａ、８ｂは夫々フロントケース１の音通過孔１ａの周縁およびコンデンサマイクロホン２に圧接されており、無線機器内部に水が侵入することを防止する。   The loop-shaped ribs 8a and 8b provided in the packing 8 are in pressure contact with the periphery of the sound passage hole 1a of the front case 1 and the condenser microphone 2, respectively, and prevent water from entering the wireless device.

また、フロントケース１の音通過孔１ａを塞ぐようにメッシュシート３がフロントケース１に張り付けられ、コンデンサマイクロホン２の音通過孔１ａと対向する面には防水布４が張り付けられていた。   Further, the mesh sheet 3 is attached to the front case 1 so as to close the sound passage hole 1a of the front case 1, and the waterproof cloth 4 is attached to the surface of the condenser microphone 2 facing the sound passage hole 1a.

音通過孔１ａの正面から図示の矢印で示す方向に水圧がかかる場合には、メッシュシート３で水勢をある程度和らげ、さらに、防水布４でコンデンサマイクロホン２内に水が入るのを防止する。   When water pressure is applied from the front of the sound passage hole 1a in the direction indicated by the arrow in the drawing, the water force is moderated to some extent by the mesh sheet 3, and further, the waterproof cloth 4 prevents water from entering the condenser microphone 2.

上記した従来のマイクロホンの防水構造によると、多少の水が外側からかかる程度であればよいが、多量の水噴流がかかる場合や、機器が水没した場合には急激な水圧変化に防水布が耐えられずマイクロホンが破損する恐れがあった。   According to the waterproof structure of the conventional microphone described above, it is sufficient that some amount of water is applied from the outside. The microphone could be damaged.

また、水没した状態から機器を取り出した場合に、メッシュシート３と防水布４との間のマイクロホン前面空間に水の表面張力により水が溜まり音圧が著しく低下する傾向があった。   Further, when the device is taken out from the submerged state, water has accumulated in the space in front of the microphone between the mesh sheet 3 and the waterproof cloth 4 due to the surface tension of the water, and the sound pressure tends to decrease remarkably.

特開２００２−１６３７４号公報に示された携帯電話機の音響部品の防水構造ではケース本体１の音響部品６前面に設けられた放音孔２を塞ぐように防水膜３が張り付けられている。   In the waterproof structure of an acoustic component of a mobile phone disclosed in Japanese Patent Application Laid-Open No. 2002-16374, a waterproof film 3 is attached so as to close the sound emitting hole 2 provided on the front surface of the acoustic component 6 of the case body 1.

上記した特開２００２−１６３７４号公報に示された防水構造では放音孔２から音響部品６の側に水が侵入することが防水膜３により防ぐことができるが、防水膜３をケース本体１に張り付ける工程が必要であり、製造コストが高くなるという問題があった。
特開平２０００−１６３７４号公報、段落００１２、図２ In the waterproof structure disclosed in Japanese Unexamined Patent Application Publication No. 2002-16374 described above, water can be prevented from entering the sound component 6 from the sound emitting hole 2 by the waterproof film 3. There is a problem that a process of attaching to the substrate is necessary and the manufacturing cost is increased.
Japanese Patent Laid-Open No. 2000-16374, paragraph 0012, FIG.

この発明は上記した点に鑑みてなされたものであって、その目的とするところは、ケースとマイクロホンとの間にパッキングを介装するだけで、水噴流がかかる場合や、機器が水没した場合にもマイクロホンへの水の侵入を防止でき、また、マイクロホン前面空間に水が溜まることを防止できるマイクロホンの防水構造を提供することにある。   The present invention has been made in view of the above points, and the object of the present invention is when a water jet is applied or a device is submerged just by inserting a packing between the case and the microphone. It is another object of the present invention to provide a waterproof structure for a microphone that can prevent water from entering the microphone and prevent water from accumulating in the front space of the microphone.

この発明の無線機器内部に配置されるマイクロホンの防水構造は、ケースに設けられた音通過孔の周縁に圧接するように前記ケースとマイクロホンとの間に介装されるパッキングに弁を一体に形成し、前記音通過孔から水圧が印加されるとその水圧により前記弁が弾性変形して前記前記音通過孔を塞ぐように構成したものである。   The waterproof structure of the microphone disposed inside the wireless device according to the present invention is such that a valve is integrally formed in a packing interposed between the case and the microphone so as to be pressed against the periphery of the sound passage hole provided in the case. When the water pressure is applied from the sound passage hole, the valve is elastically deformed by the water pressure to close the sound passage hole.

また、前記マイクロホンの防水構造において、前記弁が観音開き構造に構成されているものである。   Further, in the waterproof structure of the microphone, the valve is configured in a double door structure.

また、同マイクロホンの防水構造において、前記弁が前記パッキングに設けられた弁座に圧接されるものである。   In the waterproof structure of the microphone, the valve is pressed against a valve seat provided in the packing.

また、前記マイクロホンの防水構造において、前記弁の縁が前記弁座に近接するように傾斜した傘形状に形成されているものである。   Further, in the waterproof structure of the microphone, it is formed in an umbrella shape that is inclined so that an edge of the valve is close to the valve seat.

また、前記各マイクロホンの防水構造において、前記パッキングに前記ケースに設けられた音通過孔の周縁に圧接されるループ状のリブを設けたものである。   In the waterproof structure of each of the microphones, a loop-shaped rib that is pressed against the periphery of a sound passage hole provided in the case is provided on the packing.

また、前記各マイクロホンの防水構造において、前記音通過孔にメッシュシートを配置したものである。   Further, in the waterproof structure of each microphone, a mesh sheet is disposed in the sound passage hole.

この発明のマイクロホンの防水構造によれば、マイクロホンへの水の侵入が防止できる。従って、防水性能を高めたマイクロホンを用いることなく、通常のマイクロホンを使用できる。   According to the waterproof structure of the microphone of the present invention, water can be prevented from entering the microphone. Therefore, a normal microphone can be used without using a microphone with improved waterproof performance.

さらに、多量の水噴流や水没による水圧がかかってもマイクロホン前面空間に水が多量に溜まることがなく、音圧の低下が防止される。   Furthermore, even when a large amount of water jets or water pressure due to submergence is applied, a large amount of water does not accumulate in the front space of the microphone, and a decrease in sound pressure is prevented.

以下この発明を実施するための最良の形態を実施例に即して説明する。   The best mode for carrying out the present invention will be described below with reference to examples.

図１はこの発明の実施例１である無線機器のマイクロホンの防水構造を示す断面図である。図１に示すフロントケース１には音通過孔１ａが設けられ音通過孔１ａの内部にコンデンサマイクロホン２（ＥＣＭ）が配置されている。フロントケース１とコンデンサマイクロホン２の間にはゴム製のパッキング５が介装されている。   1 is a cross-sectional view showing a waterproof structure of a microphone of a wireless device which is Embodiment 1 of the present invention. The front case 1 shown in FIG. 1 is provided with a sound passage hole 1a, and a condenser microphone 2 (ECM) is disposed inside the sound passage hole 1a. Between the front case 1 and the condenser microphone 2, a rubber packing 5 is interposed.

パッキング５に設けられたループ状のリブ５ａ、５ｂは夫々フロントケース１の音通過孔１ａの周縁およびコンデンサマイクロホン２に圧接されており、無線機器内部に水が侵入することを防止する。   The loop-shaped ribs 5a and 5b provided in the packing 5 are in pressure contact with the periphery of the sound passage hole 1a of the front case 1 and the condenser microphone 2, respectively, and prevent water from entering the wireless device.

また、フロントケース１の音通過孔１ａを塞ぐようにメッシュシート３がフロントケース１に張り付けられている。パッキング５の前側には音通過孔１ａと対向する位置に弾性変形可能な観音開き形状の弁５ｃ、５ｃが形成されている。   A mesh sheet 3 is attached to the front case 1 so as to close the sound passage hole 1 a of the front case 1. Formed on the front side of the packing 5 are double-opened valves 5c and 5c that are elastically deformable at positions facing the sound passage holes 1a.

上記構成において、音通過孔１ａの正面から図示の矢印で示す方向に水圧がかかる場合には、メッシュシート３で水勢をある程度和らげ、さらに、弁５ｃ、５ｃが矢印で示す方向に変形して点線で示す位置となり水の侵入経路を塞ぎ水の侵入が完全に防止される。   In the above configuration, when water pressure is applied from the front of the sound passage hole 1a in the direction indicated by the arrow in the figure, the water force is moderated to some extent by the mesh sheet 3, and the valves 5c and 5c are deformed in the direction indicated by the arrow to indicate the dotted line. It becomes the position shown by and the water intrusion route is blocked, and the invasion of water is completely prevented.

弁５ｃ、５ｃが水の侵入経路を閉じた状態から水圧が除かれると、弾力により弁５ｃ、５ｃが実線に示す位置となり音通過孔１ａが開かれる。このようにマイクロホン前面空間への水の侵入を防止されるのでマイクロホン前面空間に水の表面張力により水が溜まり、音圧が低下することが防止できる。この例ではパッキング５の成形が容易であり製造コストが安くなる。また、弁５ｃ、５ｃの変形量が小さくても広い音道を確保できる。   When the water pressure is removed from the state in which the valves 5c and 5c close the water intrusion path, the valves 5c and 5c are moved to the positions indicated by the solid lines by elasticity, and the sound passage hole 1a is opened. In this way, water can be prevented from entering the microphone front space, so that it is possible to prevent water from accumulating due to the surface tension of water in the microphone front space and lowering the sound pressure. In this example, the packing 5 can be easily formed and the manufacturing cost is reduced. Further, a wide sound path can be secured even if the deformation amount of the valves 5c and 5c is small.

図２はこの発明の実施例２である無線機器のマイクロホンの防水構造を示す断面図である。図２に示すフロントケース１には音通過孔１ａが設けられ音通過孔１ａの内部にコンデンサマイクロホン２が配置されている。フロントケース１とコンデンサマイクロホン２の間にはゴム製のパッキング６が介装されている。   2 is a cross-sectional view showing a waterproof structure of a microphone of a wireless device according to a second embodiment of the present invention. The front case 1 shown in FIG. 2 is provided with a sound passage hole 1a, and a condenser microphone 2 is disposed inside the sound passage hole 1a. Between the front case 1 and the condenser microphone 2, a rubber packing 6 is interposed.

パッキング６に設けられたループ状のリブ６ａ、６ｂは夫々フロントケース１の音通過孔１ａの周縁およびコンデンサマイクロホン２に圧接されており、無線機器内部に水が侵入することを防止する。   The loop-shaped ribs 6a and 6b provided in the packing 6 are in pressure contact with the periphery of the sound passage hole 1a of the front case 1 and the condenser microphone 2, respectively, and prevent water from entering the wireless device.

また、フロントケース１の音通過孔１ａを塞ぐようにメッシュシート３がフロントケース１に張り付けられている。パッキング６の前側には音通過孔１ａと対向する位置に弾性変形可能な弁６ｃ、６ｃが形成されている。また、弁６ｃ、６ｃと対向する位置に弁座６ｄがパッキング６と一体に形成されている。   A mesh sheet 3 is attached to the front case 1 so as to close the sound passage hole 1 a of the front case 1. On the front side of the packing 6, valves 6c and 6c that can be elastically deformed are formed at positions facing the sound passage hole 1a. A valve seat 6d is formed integrally with the packing 6 at a position facing the valves 6c, 6c.

上記構成において、音通過孔１ａの正面から図示の矢印で示す方向に水圧がかかる場合には、メッシュシート３で水勢をある程度和らげ、さらに、弁６ｃ、６ｃが矢印で示す方向に変形して点線で示す位置となり弁座６ｄと密接して水の侵入経路を塞ぎ水の侵入が完全に防止される。   In the above configuration, when water pressure is applied from the front of the sound passage hole 1a in the direction indicated by the arrow in the figure, the water force is moderated to some extent by the mesh sheet 3, and the valves 6c and 6c are deformed in the direction indicated by the arrow to indicate the dotted line. In the position indicated by, the intrusion path of water is closed by close contact with the valve seat 6d, and the invasion of water is completely prevented.

弁６ｃ、６ｃが水の侵入経路を閉じた状態から水圧が除かれると弾力により弁６ｃ、６ｃが実線に示す位置となり音通過孔が開かれる。このようにマイクロホン前面空間への水の侵入を防止されるのでマイクロホン前面空間に水の表面張力により水が溜まり音圧が低下することが防止できる。   When the water pressure is removed from the state in which the valves 6c and 6c close the water intrusion path, the valves 6c and 6c are moved to the positions indicated by the solid lines by elasticity, and the sound passage holes are opened. In this way, water can be prevented from entering the front space of the microphone, so that it is possible to prevent water from accumulating due to the surface tension of water in the front space of the microphone and lowering the sound pressure.

図３はこの発明の実施例３である無線機器のマイクロホンの防水構造を示す断面図である。図３に示すフロントケース１には音通過孔１ａが設けられ音通過孔１ａの内部にコンデンサマイクロホン２が配置されている。フロントケース１とコンデンサマイクロホン２の間にはゴム製のパッキング７が介装されている。   3 is a cross-sectional view showing a waterproof structure of a microphone of a wireless device which is Embodiment 3 of the present invention. The front case 1 shown in FIG. 3 is provided with a sound passage hole 1a, and a condenser microphone 2 is disposed inside the sound passage hole 1a. A rubber packing 7 is interposed between the front case 1 and the condenser microphone 2.

パッキング７に設けられたループ状のリブ７ａ、７ｂは夫々フロントケース１の音通過孔１ａの周縁およびコンデンサマイクロホン２に圧接されており、無線機器内部に水が侵入することを防止する。   Loop-like ribs 7a and 7b provided in the packing 7 are in pressure contact with the periphery of the sound passage hole 1a of the front case 1 and the condenser microphone 2, respectively, and prevent water from entering the inside of the wireless device.

また、フロントケース１の音通過孔１ａを塞ぐようにメッシュシート３がフロントケース１に張り付けられている。パッキング７の前側には音通過孔１ａと対向する位置に弾性変形可能な弁７ｃが形成されている。弁７ｃは縁が下方に傾斜した傘形となっている。また、弁７ｃと対向する位置に弁座７ｄ、７ｄがパッキング７と一体に形成されている。   A mesh sheet 3 is attached to the front case 1 so as to close the sound passage hole 1 a of the front case 1. On the front side of the packing 7, a valve 7c that can be elastically deformed is formed at a position facing the sound passage hole 1a. The valve 7c has an umbrella shape with an edge inclined downward. Further, valve seats 7d and 7d are formed integrally with the packing 7 at a position facing the valve 7c.

上記構成において、音通過孔１ａの正面から図示の矢印で示す方向に水圧がかかる場合には、メッシュシート３で水勢をある程度和らげ、さらに弁７ｃが矢印で示す方向に変位して傘形の縁が弁座７ｄと密接して水の侵入経路を塞ぎ水の侵入が完全に防止される。弁７ｃと弁座７ｄとの圧接面積が小さいので圧接圧力が大きく水漏れが防止される。   In the above configuration, when water pressure is applied from the front of the sound passage hole 1a in the direction indicated by the arrow shown in the figure, the water force is moderated to some extent by the mesh sheet 3, and the valve 7c is displaced in the direction indicated by the arrow to cause an umbrella-shaped edge. However, it closes the valve seat 7d and closes the water intrusion route, so that the invasion of water is completely prevented. Since the pressure contact area between the valve 7c and the valve seat 7d is small, the pressure contact pressure is large and water leakage is prevented.

弁７ｃが水の侵入経路を閉じた状態から水圧が除かれると弁７ｃの支持部の弾力により弁７ｃが図３に示す位置となり音道が開かれる。このようにマイクロホン前面空間への水の侵入を防止されるのでマイクロホン前面空間に水の表面張力により水が溜まり音圧が低下することが防止できる。   When the water pressure is removed from the state where the valve 7c closes the water intrusion path, the elastic force of the support portion of the valve 7c brings the valve 7c into the position shown in FIG. 3 and the sound path is opened. In this way, water can be prevented from entering the front space of the microphone, so that it is possible to prevent water from accumulating due to the surface tension of water in the front space of the microphone and lowering the sound pressure.

図４はこの発明の実施例４である無線機器のマイクロホンの防水構造を示す断面図である。図４に示すフロントケース１には音通過孔１ａが設けられ音通過孔１ａの内部にコンデンサマイクロホン２が配置されている。フロントケース１とコンデンサマイクロホン２の間にはゴム製のパッキング８が介装されている。   4 is a cross-sectional view showing a waterproof structure of a microphone of a wireless device according to a fourth embodiment of the present invention. The front case 1 shown in FIG. 4 is provided with a sound passage hole 1a, and a condenser microphone 2 is disposed inside the sound passage hole 1a. A rubber packing 8 is interposed between the front case 1 and the condenser microphone 2.

パッキング８に設けられたループ状のリブ８ａ、８ｂは夫々フロントケース１の音通過孔１ａの周縁およびコンデンサマイクロホン２に圧接されており、無線機器内部に水が侵入することを防止する。   The loop-shaped ribs 8a and 8b provided in the packing 8 are in pressure contact with the periphery of the sound passage hole 1a of the front case 1 and the condenser microphone 2, respectively, and prevent water from entering the wireless device.

また、フロントケース１の音通過孔１ａを塞ぐようにメッシュシート３がフロントケース１に張り付けられている。パッキング８の前側には音通過孔１ａと対向する位置に平板状の弁８ｃが弾性変形可能に形成されている。また、弁８ｃと対向する位置に弁座８ｄ、８ｄがパッキング８と一体に形成されている。   A mesh sheet 3 is attached to the front case 1 so as to close the sound passage hole 1 a of the front case 1. A flat valve 8c is formed on the front side of the packing 8 so as to be elastically deformable at a position facing the sound passage hole 1a. Further, valve seats 8d and 8d are formed integrally with the packing 8 at a position facing the valve 8c.

上記構成において、音通過孔１ａの正面から図示の矢印で示す方向に水圧がかかる場合には、メッシュシート３で水勢をある程度和らげ、さらに弁８ｃが矢印で示す方向に変位して弁座８ｄと密接して水の侵入経路を塞ぎ水の侵入が完全に防止される。   In the above configuration, when water pressure is applied from the front of the sound passage hole 1a in the direction indicated by the arrow in the drawing, the water force is moderated to some extent by the mesh sheet 3, and the valve 8c is displaced in the direction indicated by the arrow to The water intrusion route is tightly closed and water intrusion is completely prevented.

弁８ｃが水の侵入経路を閉じた状態から水圧が除かれると弁８ｃの支持部の弾力により弁８ｃが図４に示す位置となり音道が開かれる。このようにマイクロホン前面空間への水の侵入を防止されるのでマイクロホン前面空間に水の表面張力により水が溜まり音圧が低下することが防止できる。   When the water pressure is removed from the state in which the valve 8c closes the water intrusion path, the elastic force of the support portion of the valve 8c brings the valve 8c into the position shown in FIG. 4 and the sound path is opened. In this way, water can be prevented from entering the front space of the microphone, so that it is possible to prevent water from accumulating due to the surface tension of water in the front space of the microphone and lowering the sound pressure.

実施例は以上のように構成されているが発明はこれに限られず、例えば、パッキングをゴムで形成する代わりに、合成ゴム等のゴム弾性を有する材料で作ることも可能である。   The embodiment is configured as described above, but the invention is not limited to this. For example, instead of forming the packing from rubber, the packing can be made of a material having rubber elasticity such as synthetic rubber.
