Description

本発明は、通話用のマイクを内蔵したリモコン装置に関するものである。 The present invention relates to a remote control device having a built-in microphone for telephone calls.

従来より、この種のリモコン装置においては、特許文献１のように、プラスチック製のリモコンケース内に電気部品を装着するための銅配線が施された基板と、キー入力を認識するためのタクトキーと、このタクトキーに操作者の指の押圧を伝えるボタンを有し、操作者の指がボタンを操作したときに、リモコンケースとボタンの隙間から静電気が侵入して基板や電気部品を破壊することを防止するために、基板の表面に絶縁シートを貼り付けたり、基板とボタンの距離を大きくとることで、静電気が原因の故障を防止するものであった。（例えば、特許文献１参照） Conventionally, in this type of remote control device, as in Patent Document 1, a substrate on which copper wiring is provided for mounting electrical components in a plastic remote control case and a tact key for recognizing a key input are used. This tact key has a button that transmits the pressure of the operator's finger, and when the operator's finger operates the button, static electricity invades through the gap between the remote control case and the button and destroys the board and electrical parts. In order to prevent this, an insulating sheet is attached to the surface of the substrate or the distance between the substrate and the button is increased to prevent a failure caused by static electricity. (See, for example, Patent Document 1)

また、図7の従来例のように、前記ボタンに比較して使用者が触れる頻度は少ないが、通話用のマイク孔ａからマイクｂを介して基板ｃに静電気が侵入すること防止する必要がある。そこで、前記マイク孔ａを備える前ケースｄと前記マイクｂの間に内部カバーｅを設けることで、前記マイク孔ａから侵入する静電気を中間に位置する内部カバーｅに逃がして、マイクｂから基板ｃへ静電気が侵入することを防止するものであった。 Further, as in the conventional example of FIG. 7, the user touches the button less frequently than the button, but it is necessary to prevent static electricity from entering the substrate c from the microphone hole a for a call via the microphone b. be. Therefore, by providing the inner cover e between the front case d provided with the microphone hole a and the microphone b, the static electricity entering from the microphone hole a is released to the inner cover e located in the middle, and the substrate is released from the microphone b. It was intended to prevent static electricity from entering c.

ところが、この種のリモコン装置は、奥行き寸法を薄くしてコンパクト化することで、外観を向上すると共に、コストダウンを行う課題がある。前者のように、絶縁シートを使用すればコストの大幅な上昇を招く。また、後者のように、内部カバーｅを使用したり、基板とボタン（前ケースｄ）の距離を大きくすれば、コストの上昇だけでなく、奥行き寸法が厚くなりコンパクト化や外観の向上の妨げとなるものだった。 However, this type of remote controller has a problem of improving the appearance and reducing the cost by reducing the depth dimension and making it compact. As in the former case, the use of an insulating sheet causes a significant increase in cost. Further, as in the latter case, if the inner cover e is used or the distance between the board and the button (front case d) is increased, not only the cost increases but also the depth dimension becomes thicker, which hinders compactness and improvement of appearance. It was something that became.

本発明は上記課題を解決するため、マイクをリモコンケースに内蔵したリモコン装置において、前記リモコンケースは前ケースと後ケースで形成し、前記マイクの前面略中央には受信部を有し、前記前ケースの前面にマイク孔を有し、前記マイク孔の後部に円筒状のマイク取付壁を立設し、前記マイク取付壁内に、前記マイクの周囲を包囲するマイクパッキンを有し、前記受信部前方のマイクパッキン前面にはパッキン孔を形成し、前記マイク孔は前記パッキン孔よりも下方に連通して設け、マイク取付壁の後方には電子部品を取り付ける基板を備え、マイクパッキンに対向する前ケースの裏面に逆Ｕ字型のリブを立設し、リブによって形成する空間の上部にパッキン孔を、リブによって形成する空間の下部にマイク孔を形成し、リブと基板の間に、マイクパッキンで包囲したマイクを押圧して固定する。
In order to solve the above problems, in a remote control device in which a microphone is built in a remote control case, the remote control case is formed of a front case and a rear case, and has a receiving unit substantially in the center of the front surface of the microphone. The receiver has a microphone hole on the front surface of the case, a cylindrical microphone mounting wall is erected behind the microphone hole, and a microphone packing that surrounds the microphone is provided in the microphone mounting wall. A packing hole is formed on the front surface of the front microphone packing, the microphone hole is provided so as to communicate below the packing hole, and a substrate for mounting an electronic component is provided behind the microphone mounting wall before facing the microphone packing. An inverted U-shaped rib is erected on the back surface of the case, a packing hole is formed in the upper part of the space formed by the rib, and a microphone hole is formed in the lower part of the space formed by the rib. in fixed to press the siege and microphone.

リモコン装置の奥行き寸法を薄くしても、マイク孔からの静電気の侵入を防止して、外観を向上すると共に、コストダウンを行うことができる。 Even if the depth dimension of the remote controller device is reduced, it is possible to prevent static electricity from entering through the microphone hole, improve the appearance, and reduce the cost.

次に、本発明の一実施形態を、インターホン機能付給湯機で使用するリモコン装置で、図面に基づいて説明する。 Next, an embodiment of the present invention will be described with reference to the drawings with a remote control device used in a water heater with an intercom function.

リモコン装置１は、内蔵部品の前面側を覆う樹脂製の前ケース２と、後面側を覆う樹脂製の後ケース３とで構成される薄い箱状のリモコンケース４に、液晶表示部５や通話スイッチを含む複数のスイッチ６などの電子部品を装着するための銅配線が施された電装基板７やスピーカー８、マイク９等を内蔵し、前ケース２の前面側には複数の操作キー１０を押圧自在に嵌め込んで取り付けられている。 The remote controller 1 includes a thin box-shaped remote controller case 4 composed of a resin front case 2 that covers the front side of the built-in components and a resin rear case 3 that covers the rear surface side, and a liquid crystal display unit 5 and a call. It has a built-in electrical board 7, speaker 8, microphone 9, etc. with copper wiring for mounting electronic components such as a plurality of switches 6 including a switch, and has a plurality of operation keys 10 on the front side of the front case 2. It is attached by fitting it freely.

前ケース２は左端下隅裏面に直径３ｍｍのマイク孔１１を備え、このマイク孔１１の後部に円筒状のマイク取付壁１２を立設し、このマイク取付壁１２内に背面側から円盤状の前記マイク９が固定される。このマイク９の背面または側面からはリード線１３が半田付けで接続され、このリード線１３の他端には端子１４を有している。この端子１４は前記基板7の背面に備えたコネクタ１５に接続している。前記マイク９は前面の略中心に音声を検出する受信部１６を有している。 The front case 2 is provided with a microphone hole 11 having a diameter of 3 mm on the back surface of the lower left corner, and a cylindrical microphone mounting wall 12 is erected at the rear portion of the microphone hole 11, and the disk-shaped front case is formed in the microphone mounting wall 12 from the back side. The microphone 9 is fixed. A lead wire 13 is soldered from the back surface or the side surface of the microphone 9, and a terminal 14 is provided at the other end of the lead wire 13. The terminal 14 is connected to a connector 15 provided on the back surface of the substrate 7. The microphone 9 has a receiving unit 16 that detects sound at a substantially center of the front surface.

１７は前記マイク９の周囲を柔軟なゴムで包囲するマイクパッキンで、マイク９の前面側に位置し、背面が凹状の前パッキン１８と、マイク９の背面側に位置し、筒状の前面内にマイク９を装着する後パッキン１９を、連結部２０で連結して一体に一部品として成型されている。また、前記受信部１６前方の前記前パッキン１８にはパッキン孔２１を形成することで、受信部１６の前方を開口している。また、後パッキン１９にマイク９を装着後に前パッキン１８を被せてマイク９の周囲を包囲する。また、後パッキン１９の側面には前記リード線１３を引き出すためのパッキン切欠き２２を備えている。 Reference numeral 17 denotes a microphone packing that surrounds the microphone 9 with a flexible rubber. The front packing 18 is located on the front side of the microphone 9 and has a concave back surface, and the front packing 18 is located on the back side of the microphone 9 and has a tubular front surface. After mounting the microphone 9 on the back, the packing 19 is connected by the connecting portion 20 and integrally molded as one part. Further, the front of the receiving unit 16 is opened by forming a packing hole 21 in the front packing 18 in front of the receiving unit 16. Further, after the microphone 9 is attached to the rear packing 19, the front packing 18 is covered to surround the microphone 9. Further, a packing notch 22 for pulling out the lead wire 13 is provided on the side surface of the rear packing 19.

２３は前記前ケース２裏面のマイク取付壁１２内側に逆Ｕ字型に立設したリブで、前記マイク孔１１とパッキン孔２１の間を連通する空間２４を形成する。これによって、マイク孔１１から侵入する静電気を図６の破線矢印で示すように下方から上方へ蛇行させることで、静電気がマイク９から侵入することを防止する。また、マイク孔１１とパッキン孔２１の間を連通する空間２４を直線状にするこで、通話性能を向上することができる。また、前ケース２の成型時に前ケース２前面側に発生するヒケ（窪み）を少なくすることができる。 Reference numeral 23 denotes an inverted U-shaped rib erected inside the microphone mounting wall 12 on the back surface of the front case 2, forming a space 24 communicating between the microphone hole 11 and the packing hole 21. As a result, the static electricity entering through the microphone hole 11 meanders from the bottom to the top as shown by the broken line arrow in FIG. 6, thereby preventing the static electricity from entering through the microphone 9. Further, by making the space 24 communicating between the microphone hole 11 and the packing hole 21 linear, the call performance can be improved. Further, it is possible to reduce sink marks (dents) generated on the front side of the front case 2 when the front case 2 is molded.

組み立て手順について説明すれば、まずマイク９のリード線１３位置を後パッキン１９のパッキン切欠き２２に合わせて後パッキン１５に嵌め込む。次に、前パッキン１４をマイク９の前方を覆って嵌め合わせればマイクパッキン１７によってマイク９が包囲される。次に、マイクパッキン１７で覆ったマイク９のパッキン孔２１がマイク孔１１側（前方）になるようにマイク取付壁１２に押し込めば、マイク孔１１とパッキン孔２１の間を連通する空間２４を形成する。このとき、リード線１３とマイクパッキン１７の連結部２０はマイク取付壁１２に２箇所備える壁切欠き２５によってマイク取付壁１２の側面から引き出したり、突出することでマイクパッキン１７とマイク取付壁１２を密着させる。 To explain the assembly procedure, first, the lead wire 13 of the microphone 9 is aligned with the packing notch 22 of the rear packing 19 and fitted into the rear packing 15. Next, if the front packing 14 is fitted so as to cover the front of the microphone 9, the microphone 9 is surrounded by the microphone packing 17. Next, if the packing hole 21 of the microphone 9 covered with the microphone packing 17 is pushed into the microphone mounting wall 12 so as to be on the microphone hole 11 side (front), the space 24 communicating between the microphone hole 11 and the packing hole 21 is created. Form. At this time, the connecting portion 20 of the lead wire 13 and the microphone packing 17 is pulled out from the side surface of the microphone mounting wall 12 or protrudes from the side surface of the microphone mounting wall 12 by the wall notches 25 provided at two points on the microphone mounting wall 12, so that the microphone packing 17 and the microphone mounting wall 12 are connected. In close contact.

次に、端子１４を基板７のコネクタ１５に差し込んだ後、前ケース２の裏面にスピーカー８と共にネジ止め等でセットし、後ケース３を前ケース２にネジ止めまたは嵌合等によって取り付ければ、後パッキン１５の背面を基板７の前面が押圧してマイク９を正しい位置にセットして組み立てが完了する。 Next, after the terminal 14 is inserted into the connector 15 of the board 7, it is set on the back surface of the front case 2 together with the speaker 8 by screwing or the like, and the rear case 3 is attached to the front case 2 by screwing or fitting. The front surface of the substrate 7 presses the back surface of the rear packing 15, and the microphone 9 is set in the correct position to complete the assembly.

このように、本件発明によれば、リモコン装置の奥行き寸法を薄くしても、マイク孔１１からの静電気の侵入を防止して、外観を向上すると共に、コストダウンを行うことができる。また、後パッキン１５の背面を基板７の前面が押圧しマイク９を密着してセットすることができる。 As described above, according to the present invention, even if the depth dimension of the remote controller device is reduced, it is possible to prevent the intrusion of static electricity from the microphone hole 11, improve the appearance, and reduce the cost. Further, the back surface of the rear packing 15 is pressed by the front surface of the substrate 7, and the microphone 9 can be set in close contact with the microphone 9.

なお、本発明は上記一実施形態に限定されるものではなく、発明の要旨を変更しない範囲で改変可能なものである。 The present invention is not limited to the above embodiment, and can be modified without changing the gist of the invention.
