音声出力装置Audio output device
　本発明は、スピーカユニット等の出力部から出力される音波を反射させる反射板を備える音声出力装置に関する。 The present invention relates to an audio output device including a reflector that reflects sound waves output from an output unit such as a speaker unit.
　テレビ受像機やオーディオ機器等の音波（以下、単に「音」と称す）を出力することができる機器を構成する、音を出力するスピーカユニット等の出力部が接続されてなる音声出力装置には、出力部と当該音声出力装置の利用者との位置関係から利用者が音を聴き取り難いという理由で、出力部から出力される音を反射させる反射板を備えるものがある（例えば、特許文献１、２参照）。 An audio output device connected to an output unit such as a speaker unit that outputs sound, which constitutes a device capable of outputting sound waves (hereinafter simply referred to as “sound”) such as a television receiver or an audio device. Some of them include a reflector that reflects the sound output from the output unit because it is difficult for the user to hear the sound because of the positional relationship between the output unit and the user of the audio output device (for example, Patent Documents). 1 and 2).
　特許文献１に記載の音声出力装置は、テレビ受像機のキャビネット内に設置され、このテレビ受像機の側方外向きに音を出力する。テレビ受像機のキャビネットの側面には、後端部に回動軸を備えた反射板が装着されており、反射板の反射板本体が回動軸によって回動する。反射板本体に形成されている突起部と、反射板が備える第２差込部の凹部とを係合することによって、反射板本体が位置決め保持される。 The audio output device described in Patent Document 1 is installed in a cabinet of a television receiver, and outputs sound outward from the side of the television receiver. On the side surface of the cabinet of the television receiver, a reflection plate having a rotation shaft at the rear end is mounted, and the reflection plate body of the reflection plate is rotated by the rotation shaft. The reflecting plate main body is positioned and held by engaging the protrusion formed on the reflecting plate main body with the concave portion of the second insertion portion provided in the reflecting plate.
　特許文献２に記載の音声出力装置は、電子楽器のキャビネット内に設置され、電子楽器の上方に向けて音を出力する。電子楽器のキャビネットの上面には、音反射板が後部の支点を中心として前端が上下可動に支持されている。音反射板の下部に反射板持ち上げバネが配されており、音反射板は常に上方へ向かって力を受けている。 The audio output device described in Patent Document 2 is installed in an electronic musical instrument cabinet and outputs sound toward the upper side of the electronic musical instrument. On the upper surface of the cabinet of the electronic musical instrument, a sound reflecting plate is supported so that the front end is movable up and down around a fulcrum at the rear. A reflection plate lifting spring is disposed below the sound reflection plate, and the sound reflection plate always receives a force upward.
　一方、音声出力装置には、残響を付加することで音場拡大を図るために、出力された音を反射させる反射板を備えるものもある（例えば、特許文献３参照）。特許文献３に記載の音声出力装置は、テレビ受像機等から独立したスピーカのバッフル板内に設置され、スピーカの斜め前方へ向けて音を出力する。バッフル版のスピーカに対向する位置には、回動可能に、且つ所望のところで制止できるように反射板が取り付けられており、反射板によって出力された音がスピーカの後方に反射される。 On the other hand, some audio output devices include a reflector that reflects the output sound in order to expand the sound field by adding reverberation (see, for example, Patent Document 3). The audio output device described in Patent Document 3 is installed in a baffle plate of a speaker independent from a television receiver or the like, and outputs sound toward a diagonally forward direction of the speaker. A reflection plate is attached at a position facing the baffle speaker so that it can rotate and can be stopped at a desired position, and the sound output by the reflection plate is reflected to the rear of the speaker.

　ところで、音声出力装置から出力される音は、例えば音声出力装置がテレビ受像機に設置されている場合、ニュース、映画、コンサート等の音楽又はスポーツ等の様々なジャンルに分類された放送番組のコンテンツを構成する。分類されたジャンルの種類によって、適切な音響の度合い（音場）は異なるものの、ジャンルの種類に対応して音場を変化させ得る音声出力装置はない。 By the way, the sound output from the audio output device is broadcast program content classified into various genres such as music such as news, movies, concerts, or sports when the audio output device is installed in a television receiver, for example. Configure. Although the appropriate degree of sound (sound field) differs depending on the type of categorized, there is no audio output device that can change the sound field corresponding to the type of genre.
　特許文献１乃至３の音声出力装置は、利用者が音を良好に聴くために、又は、残響を付加するために、反射板によって音を反射させるので、音響を変化させ得るが、ジャンルの種類に対応して自動的に音響を変化させることはできない。 The sound output devices of Patent Documents 1 to 3 can change the sound because the sound is reflected by the reflector so that the user can listen to the sound satisfactorily or add reverberation. The sound cannot be changed automatically in response to
　本発明は上記背景より、出力される音を含むコンテンツのジャンルに対応して自動的に音響を変更することができる音声出力装置を提案するものである。 The present invention proposes an audio output device that can automatically change the sound in accordance with the genre of the content including the output sound from the above background.

（実施の形態１）
　以下、図面を用いて本発明を実施するための最良の形態を説明する。図１に、本発明の音声出力装置１がテレビ受像機Ｘに適用されている具体例を示す。最初にテレビ受像機Ｘの全体的な構造について説明する。なお、本発明の音声出力装置１は、テレビ受像機Ｘの他に、オーディオ機器やパーソナルコンピュータのモニタ等の出力手段、電子楽器等の音を出力する機能を有する機器に適用することが可能である。図２では、音声出力装置１は、テレビ受像機Ｘの映像出力部を構成する、液晶ディスプレイやプラズマディスプレイのパネル２の下方に設置されているが、音声出力装置１の位置はこれに限られず、この他に例えば、パネル２の側方に設置されることも可能である（図１２参照）。 (Embodiment 1)
Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. FIG. 1 shows a specific example in which the audio output device 1 of the present invention is applied to a television receiver X. First, the overall structure of the television receiver X will be described. In addition to the television receiver X, the audio output device 1 of the present invention can be applied to audio equipment, output means such as a monitor of a personal computer, and equipment having a function of outputting sound such as an electronic musical instrument. is there. In FIG. 2, the audio output device 1 is installed below the liquid crystal display or plasma display panel 2 constituting the video output unit of the television receiver X, but the position of the audio output device 1 is not limited to this. In addition to this, for example, it can be installed on the side of the panel 2 (see FIG. 12).
　また、図２では、音声出力装置１は、音が出力される（音源となる）出力部である複数のスピーカユニット１Ｂ（図２において３個）と、スピーカユニット１Ｂから出力された音を反射させる反射装置１Ａとを備える。反射装置１Ａ及びスピーカユニット１Ｂはテレビ受像機Ｘのキャビネット３に収容されている。 In FIG. 2, the audio output device 1 reflects a plurality of speaker units 1 </ b> B (three in FIG. 2) that are output units that output sound (becomes sound sources) and the sound output from the speaker unit 1 </ b> B. And a reflecting device 1A. The reflection device 1A and the speaker unit 1B are accommodated in the cabinet 3 of the television receiver X.
　図２に示すように、音源が複数のスピーカユニット１Ｂで構成される場合、各スピーカユニット１Ｂは、例えばウーファー（低音用）、スコーカー（中音用）又はツイーター（高音用）等の帯域毎に分割された各種のスピーカユニットが組み合わされてなる。音源が単数のスピーカユニット１Ｂで構成される場合（図示せず）、フルレンジスピーカー（中音域を中心に低音域及び高音域の特性を確保する機能を有する）であることが望ましい。広範囲な可聴域の音（音声、音楽、効果音等）を提供することができるからである。スピーカユニット１Ｂの個数は、コスト等の諸条件に応じて適宜に設計される。 As shown in FIG. 2, when the sound source is composed of a plurality of speaker units 1B, each speaker unit 1B is provided for each band such as a woofer (for low sounds), a squawker (for medium sounds), or a tweeter (for high sounds). Various divided speaker units are combined. When the sound source is composed of a single speaker unit 1B (not shown), it is desirable that the sound source is a full-range speaker (having a function of ensuring the characteristics of the low sound range and the high sound range centering on the middle sound range). This is because a wide range of audible sounds (voice, music, sound effects, etc.) can be provided. The number of speaker units 1B is appropriately designed according to various conditions such as cost.
　反射装置１Ａを構成する制御装置２０は、例えばテレビ受像機Ｘが放送局等から発信された放送信号Ｓ０を直接にあるいは間接に受信することによって、放送信号Ｓ０を構成する番組情報を読み取り、番組情報に含まれる、分類された番組のジャンルを表す情報（以下、ジャンル情報という）に応じて反射板１１を駆動制御する（図８参照）。反射板１１は、読み取ったジャンル情報に応じて、例えば図３（ａ）～（ｄ）に示すような態様で駆動する。 The control device 20 constituting the reflection device 1A reads the program information constituting the broadcast signal S0, for example, when the television receiver X receives the broadcast signal S0 transmitted from a broadcasting station or the like directly or indirectly, The reflector 11 is driven and controlled according to information (hereinafter referred to as genre information) representing the genre of the classified program included in the information (see FIG. 8). The reflecting plate 11 is driven in a manner as shown in FIGS. 3A to 3D, for example, according to the read genre information.
　放送信号Ｓ０は、地上デジタル放送、ＢＳデジタル放送、１１０度ＣＳ放送を行う放送局より送信される、利用者が視聴するコンテンツに関する信号であって、映像信号Ｓ４、音声信号Ｓ５及びコンテンツの内容に関する情報の信号（以下、番組情報信号Ｓ６という）が時分割複合化された多重化信号である。図８に示すように、放送局から送信された放送信号Ｓ０は、テレビ受像機Ｘのアンテナ２１によって直接受信され、チューナ２２を介して、復調処理される。 The broadcast signal S0 is a signal related to the content viewed by the user, transmitted from a broadcasting station that performs terrestrial digital broadcasting, BS digital broadcasting, and 110-degree CS broadcasting, and is related to the content of the video signal S4, the audio signal S5, and the content. This is a multiplexed signal in which an information signal (hereinafter referred to as program information signal S6) is time-division combined. As shown in FIG. 8, the broadcast signal S0 transmitted from the broadcast station is directly received by the antenna 21 of the television receiver X and demodulated through the tuner 22.
　本実施の形態では、テレビ受像機Ｘがそのアンテナ２１によって放送信号Ｓ０を受信する形態であるが、例えば、テレビ受像機Ｘが録音再生装置（図示せず）に電気的に接続されており、録音再生装置が放送信号Ｓ０を受信して、テレビ受像機Ｘが録音再生装置を介して間接に放送信号Ｓ０を受信する形態であってもよい。 In the present embodiment, the television receiver X is configured to receive the broadcast signal S0 through the antenna 21. For example, the television receiver X is electrically connected to a recording / playback apparatus (not shown). The recording / playback apparatus may receive the broadcast signal S0, and the television receiver X may receive the broadcast signal S0 indirectly via the recording / playback apparatus.
　また、本実施の形態では、コンテンツが放送番組であるので音響制御パターンは放送信号Ｓ０の番組情報に含まれているが、例えばコンテンツがコンパクトディスク（ＣＤ）やデジタルヴァーサタイルディスク（ＤＶＤ）等の記憶媒体に記憶されている曲目である場合には、音響制御パターンはコンテンツを表す音声信号に含まれるようにすることも可能である。 In this embodiment, since the content is a broadcast program, the sound control pattern is included in the program information of the broadcast signal S0. For example, the content is a compact disc (CD), a digital versatile disc (DVD), or the like. When the music is stored in the storage medium, the acoustic control pattern can be included in the audio signal representing the content.
　図３（ａ）では、制御装置２０による制御が完了した時点で反射板１１は、反射板１１の下端部とスピーカユニット１Ｂの上端部とが略一致する程度まで上昇した状態で保持されるので、スピーカユニットＢの前方は開放される。したがって、出力された音はそのまま直接前方へ進むので、音響が小さい。つまり、この図３（ａ）が示す反射板１１とスピーカユニット１Ｂとの最終的な位置関係は、コンテンツのジャンルが、当該番組の主要素が台詞であるニュース等の場合に適切である。 In FIG. 3A, when the control by the control device 20 is completed, the reflecting plate 11 is held in a state where it is raised to the extent that the lower end portion of the reflecting plate 11 and the upper end portion of the speaker unit 1B substantially coincide. The front of the speaker unit B is opened. Therefore, since the output sound goes directly forward as it is, the sound is small. That is, the final positional relationship between the reflector 11 and the speaker unit 1B shown in FIG. 3A is appropriate when the content genre is news or the like in which the main element of the program is dialogue.
　図３（ｂ）では、制御装置２０による制御が完了した時点で反射板１１は、スピーカユニット１Ｂの下部の前方が開放される程度まで上昇した状態、かつ、反射板１１の背面側から正面側へかけて上昇する傾斜状態で保持される。したがって、スピーカユニット１Ｂの下部から出力される音は、図３（ａ）の場合と同様に、そのまま直接前方へ進む。 In FIG. 3B, when the control by the control device 20 is completed, the reflector 11 is raised to the extent that the front of the lower part of the speaker unit 1B is opened, and from the back side to the front side of the reflector 11 It is held in an inclined state that rises toward the top. Therefore, the sound output from the lower part of the speaker unit 1B proceeds directly forward as it is, as in the case of FIG.
　一方、スピーカユニット１Ｂの上部から出力された音は、例えば、反射板１１に反射し、パネル２等のテレビ受像機Ｘの正面に反射して、前方へ斜め上向きで進むので、スピーカユニット１Ｂの下部から出力された音より遅れて利用者に到達する。反射板１１の傾斜角度、あるいは反射板１１とパネル２との水平間距離の状況によっては、反射板１１に反射された音は、反射板１１とパネル２との間を複数回反射され続けて斜め前方へ進むこともあり得る。したがって、この図３（ｂ）が示す反射板１とスピーカユニット１Ｂとの最終的な位置関係は、コンテンツのジャンルが、台詞と音楽等で構成される映画等の場合に適切である。 On the other hand, the sound output from the upper part of the speaker unit 1B is reflected, for example, on the reflection plate 11, reflected on the front of the television receiver X such as the panel 2, and proceeds forward obliquely upward. It reaches the user later than the sound output from the lower part. Depending on the inclination angle of the reflecting plate 11 or the horizontal distance between the reflecting plate 11 and the panel 2, the sound reflected by the reflecting plate 11 continues to be reflected between the reflecting plate 11 and the panel 2 a plurality of times. It is possible to go forward diagonally. Therefore, the final positional relationship between the reflector 1 and the speaker unit 1B shown in FIG. 3B is appropriate when the content genre is a movie or the like composed of dialogue and music.
　図３（ｃ）では、制御装置２０による制御が完了した時点で反射板１１は、スピーカユニット１Ｂの上部の前方が開放される程度まで下降した状態、かつ、反射板１１の背面側から正面側へかけて下降する傾斜状態で保持される。したがって、スピーカユニット１Ｂの上部から出力された音は、図３（ａ）の場合と同様に、そのまま直接前方へ進む。 In FIG. 3C, when the control by the control device 20 is completed, the reflector 11 is lowered to the extent that the front of the upper part of the speaker unit 1B is opened, and from the back side to the front side of the reflector 11 It is held in an inclined state that descends toward the top. Therefore, the sound output from the upper part of the speaker unit 1B proceeds directly forward as it is, as in the case of FIG.
　一方、スピーカユニット１Ｂの下部から出力された音は、例えば、反射板１１に反射してテレビ受像機Ｘの背面側に進むので、スピーカユニット１Ｂの上部から出力された音より遅れて利用者に到達する。ここで、反射板１１に反射された音が利用者に到達するまでの時間は、テレビ受像機Ｘの背面側の状況等に起因する。 On the other hand, the sound output from the lower part of the speaker unit 1B is reflected by the reflecting plate 11 and proceeds to the rear side of the television receiver X, for example, so that the user is delayed from the sound output from the upper part of the speaker unit 1B. To reach. Here, the time until the sound reflected by the reflecting plate 11 reaches the user is caused by the situation on the back side of the television receiver X or the like.
　つまり、反射板１１とテレビ受像機Ｘの背面側に形成された壁や家具等の音が反射可能な面との水平距離が長ければ、反射板１１に反射された音と反射板１１に反射していない音との、利用者に到達する時間差が大きくなるので、音響は大きくなる。当該テレビ受像機Ｘが設置されている空間の臨場感が増大する。したがって、この図３（ｃ）が示す反射板１とスピーカユニット１Ｂとの位置関係は、コンテンツのジャンルが、実況等の台詞が含まれるスポーツや音楽番組等の場合に適切である。 In other words, if the horizontal distance between the reflecting plate 11 and a surface formed on the back side of the television receiver X that can reflect sound, such as a wall or furniture, is long, the sound reflected by the reflecting plate 11 and the reflecting plate 11 are reflected. Since the time difference to reach the user with the sound that has not been made increases, the sound increases. The presence of the space in which the television receiver X is installed increases. Therefore, the positional relationship between the reflector 1 and the speaker unit 1B shown in FIG. 3C is appropriate when the genre of the content is a sport or music program that includes a dialogue such as a live commentary.
　また、反射板１１の傾斜角度、あるいは反射板１１とパネル２との水平間距離の状況によっては、反射板１１に反射された音は、反射板１１とパネル２との間を複数回反射され続けて斜め後方へ進むこともあり得る。 Depending on the inclination angle of the reflecting plate 11 or the horizontal distance between the reflecting plate 11 and the panel 2, the sound reflected by the reflecting plate 11 is reflected between the reflecting plate 11 and the panel 2 a plurality of times. It is also possible to continue to go diagonally backward.
　図３（ｄ）では、制御装置２０による制御が完了した時点で反射板１１は、前方へ平行移動した状態で保持される。したがって、スピーカユニット１１Ｂから水平に対して傾斜する方向に出力された音は反射板１１とスピーカ１Ｂの前面等との反射を複数回繰り返して、斜め前方上向き又は下向きに進む。よって、図３（ａ）～（ｃ）の場合に比して、当該空間内の音響が大きくなる。この図３（ｄ）が示す反射板１とスピーカユニット１Ｂの最終的な位置関係は、コンテンツのジャンルが、様々な方向から音が聞こえる演劇やコンサートの場合に適切である。 In FIG. 3D, when the control by the control device 20 is completed, the reflecting plate 11 is held in a state of being translated forward. Therefore, the sound output from the speaker unit 11B in a direction inclined with respect to the horizontal is reflected a plurality of times by the reflection plate 11 and the front surface of the speaker 1B, and proceeds obliquely upward or downward. Therefore, the sound in the space becomes larger than in the case of FIGS. 3 (a) to 3 (c). The final positional relationship between the reflector 1 and the speaker unit 1B shown in FIG. 3D is appropriate when the genre of the content is a play or concert in which sound can be heard from various directions.
　このように、反射板１１を駆動させて、反射板１１の位置又は反射板１１の水平に対する角度を変化させるという簡易な方法によって、音響、つまりは音の演出方法を変更することができる。例えば、スピーカーボックス等をテレビ受像機Ｘが設置された空間の様々な場所に設置することによって、音響効果の高い５．１ｃｈサラウンドでコンテンツを聴くことが可能ではあるが、この場合、スピーカーボックスの配線等のスピーカーボックスの設置作業に手間を要すると共に、設備費用が高価である。一方、反射板１１の駆動による音響の変更によれば、利用者の設置作業が不要であると共に、設備費用が低廉である。 Thus, the sound, that is, the sound production method can be changed by a simple method of driving the reflecting plate 11 and changing the position of the reflecting plate 11 or the angle of the reflecting plate 11 with respect to the horizontal. For example, by installing speaker boxes or the like in various places in the space where the television receiver X is installed, it is possible to listen to content in 5.1ch surround with a high acoustic effect. Installation work of the speaker box such as wiring is troublesome and the equipment cost is expensive. On the other hand, according to the change of the sound by driving the reflecting plate 11, the user's installation work is unnecessary and the equipment cost is low.
　次に、反射装置１Ａの構造について説明する。図１に示すように、反射装置１Ａの反射板１１は支持部材１２に支持されている。図１では、支持部材１２は、反射板１１の両端部下側で反射板１１に接続されている下支持部材１２Ａと、反射板１１の両端部上側で反射板１１に接続されている上支持部材１２Ｂとからなる。図面では、各支持部材１２Ａ、１２Ｂは反射板１１の両端部で接続されているが、この接続箇所はスピーカユニット１Ｂの配置等のテレビ受像機Ｘの設計によって適宜に変更される。 Next, the structure of the reflection device 1A will be described. As shown in FIG. 1, the reflection plate 11 of the reflection device 1 </ b> A is supported by a support member 12. In FIG. 1, the support member 12 includes a lower support member 12 </ b> A that is connected to the reflector 11 at the lower side of both ends of the reflector 11, and an upper support member that is connected to the reflector 11 at the upper ends of the reflector 11. 12B. In the drawing, the support members 12A and 12B are connected at both ends of the reflector 11, but this connection location is appropriately changed depending on the design of the television receiver X such as the arrangement of the speaker unit 1B.
　下支持部材１２Ａ、１２Ａ及び上支持部材１２Ｂ、１２Ｂは一端部において、それぞれ連結軸１４Ａ、１４Ｂによって連結されている。この連結軸１４Ａ、１４Ｂは、例えば反射板１１に固定されたヒンジ１７に連結軸１４Ａ、１４Ｂの周方向に回動自在に挿通している。すなわち、両支持部材１２Ａ、１２Ｂは、反射板１１に連結軸１４Ａ、１４Ｂの周方向に回動自在に接続されている。 The lower support members 12A, 12A and the upper support members 12B, 12B are connected at one end by connecting shafts 14A, 14B, respectively. The connecting shafts 14A and 14B are inserted into, for example, a hinge 17 fixed to the reflecting plate 11 so as to be rotatable in the circumferential direction of the connecting shafts 14A and 14B. That is, both support members 12A and 12B are connected to the reflecting plate 11 so as to be rotatable in the circumferential direction of the connecting shafts 14A and 14B.
　上支持部材１２Ｂ、１２Ｂは他端部においても連結軸１５によって連結されている。連結軸１５は、例えばテレビ受像機Ｘのキャビネット３の背面側の内面に固定されたヒンジ１８に挿通することで、キャビネット３に連結軸１５の周方向に回動自在に支持されている。 The upper support members 12B and 12B are also connected by the connecting shaft 15 at the other end. The connecting shaft 15 is supported by the cabinet 3 so as to be rotatable in the circumferential direction of the connecting shaft 15 by being inserted into a hinge 18 fixed to the inner surface on the back side of the cabinet 3 of the television receiver X, for example.
　一方、下支持部材１２Ａは他端部で、下支持部材１２Ａを回転させるためのモータ１６の回転軸１６ａに直交して連結されている。したがって、モータ１６が駆動して回転軸１６ａが回転すると、下支持部材１３Ａは背面側の端部を回転中心として回転する。下支持部材１３Ａと上支持部材１３Ｂとが反射板１１を介して連結されているので、下支持部材１３Ａの回転に連動して、上支持部材１３Ｂも背面側の端部を回転中心として回転する。 On the other hand, the lower support member 12A is connected to the other end at a right angle to the rotation shaft 16a of the motor 16 for rotating the lower support member 12A. Therefore, when the motor 16 is driven to rotate the rotating shaft 16a, the lower support member 13A rotates around the end portion on the back side. Since the lower support member 13A and the upper support member 13B are connected via the reflecting plate 11, the upper support member 13B also rotates around the end on the back side in conjunction with the rotation of the lower support member 13A. .
　また、両支持部材１２Ａ、１２Ｂの長さが同一、且つ両支持部材１２Ａ、１２Ｂの回転中心が鉛直方向の同一直線上に配設されている。つまり、両支持部材１２Ａ、１２Ｂの正面側先端部（連結軸１４Ａ、１４Ｂに連結されている位置）は、鉛直方向の同一直線上に並設されたモータ１６の回転軸１６ａと連結軸１５とをそれぞれの回動（回転）中心として同一の回動半径で回動する。 Further, the lengths of both support members 12A and 12B are the same, and the rotation centers of both support members 12A and 12B are arranged on the same straight line in the vertical direction. That is, the front end portions (positions connected to the connecting shafts 14A and 14B) of the support members 12A and 12B are connected to the rotating shaft 16a and the connecting shaft 15 of the motor 16 arranged on the same straight line in the vertical direction. Are rotated at the same rotation radius with each rotation (rotation) center.
　図１では反射装置１Ａは初期状態にあり、上支持部材１２Ｂと下支持部材１２Ａとは平行に保持され、両連結軸１４Ａ、１４Ｂが鉛直方向の同一直線上に位置しているので、モータ１６が駆動すると、反射板１１が水平に直交した状態で両支持部材１２Ａ、１２Ｂが回動する。ここで、初期状態とは反射装置１１が未使用である状態、すなわち、反射板１１がパネル２の下部に配設されて、スピーカユニット１Ｂの前方を塞いでいる状態のことをいう（図４（ａ）、図５（ａ）、図６（ａ）、図７（ａ）参照）。 In FIG. 1, the reflecting device 1A is in an initial state, the upper support member 12B and the lower support member 12A are held in parallel, and the connecting shafts 14A and 14B are positioned on the same straight line in the vertical direction. Is driven, both support members 12A and 12B rotate in a state where the reflector 11 is orthogonal to the horizontal. Here, the initial state refers to a state in which the reflection device 11 is not used, that is, a state in which the reflection plate 11 is disposed in the lower part of the panel 2 and closes the front of the speaker unit 1B (FIG. 4). (See (a), FIG. 5 (a), FIG. 6 (a), FIG. 7 (a)).
　また、両支持部材１２Ａ、１２Ｂの材軸方向の一区間には、その材軸方向の長さを変更するためのアクチュエータ１３Ａ、１３Ｂが介在されている。アクチュエータ１３Ａ、１３Ｂは、圧電アクチュエータや電磁アクチュエータ等の様々な型式のアクチュエータからなり、諸条件等に応じて適宜に設定される。 Further, actuators 13A and 13B for changing the length in the material axis direction are interposed in one section in the material axis direction of both support members 12A and 12B. The actuators 13A and 13B are composed of various types of actuators such as a piezoelectric actuator and an electromagnetic actuator, and are appropriately set according to various conditions.
　本実施の形態では、アクチュエータ１３Ａ、１３Ｂは電圧が印加されることによって、両支持部材１２Ａ、１２Ｂの材軸方向に変位（伸縮）する。アクチュエータ１３Ａ、１３Ｂは、その電圧値に応じて支持部材１２Ａ、１２Ｂの材軸方向に微少に伸縮する。 In the present embodiment, the actuators 13A and 13B are displaced (expanded) in the direction of the material axes of the support members 12A and 12B when a voltage is applied. The actuators 13A and 13B slightly expand and contract in the material axis direction of the support members 12A and 12B according to the voltage value.
　例えば、上支持部材１２Ｂ、１２Ｂのアクチュエータ１３Ｂ、１３Ｂが同一長さ延びると、反射板１１は連結軸１４Ｂを介して上支持部材１２Ｂ、１２Ｂから正面側へ力を受けるので、固定されている連結軸１４Ａを中心に回転し、背面側から正面側へかけて上昇する傾斜状態になる。このとき、上支持部材１２Ｂ、１２Ｂの正面側先端部は連結軸１４Ａに拘束されるので、回転自在な連結軸１５を中心にその周方向に回転する（図５（ｂ）参照）。 For example, when the actuators 13B, 13B of the upper support members 12B, 12B extend the same length, the reflector 11 receives a force from the upper support members 12B, 12B to the front side via the connection shaft 14B, so that the fixed connection is established. It rotates about the shaft 14A and enters an inclined state that rises from the back side to the front side. At this time, the front-side front ends of the upper support members 12B and 12B are constrained by the connecting shaft 14A, and thus rotate in the circumferential direction about the rotatable connecting shaft 15 (see FIG. 5B).
　一方、下支持部材１２Ａ、１２Ａのアクチュエータ１３Ａ、１３Ａが同一長さ延びると、反射板１１は連結軸１４Ａを介して下支持部材１２Ａ、１２Ａから正面側へ力を受けるので、連結軸１４Ｂを中心にその周方向に回転し、背面側から正面側へかけて下降する傾斜状態になる。ここで、モータ１６が停止していれば、連結軸１４Ａの鉛直位置は変化しないので、上支持部材１２Ｂ、１２Ｂの正面側先端部は連結軸１４Ａに拘束される。したがって、連結軸１４Ｂは反射板１１を介して反力を受けて、上支持部材１２Ａ、１２Ａと共に、連結軸１５を中心にその周方向に回転する（図６（ｂ）参照）。 On the other hand, when the actuators 13A, 13A of the lower support members 12A, 12A extend the same length, the reflecting plate 11 receives a force from the lower support members 12A, 12A to the front side via the connection shaft 14A. Rotate in the circumferential direction, and incline to descend from the back side to the front side. Here, if the motor 16 is stopped, the vertical position of the connecting shaft 14A does not change, so the front end portions of the upper support members 12B and 12B are restrained by the connecting shaft 14A. Therefore, the connecting shaft 14B receives a reaction force through the reflecting plate 11, and rotates in the circumferential direction around the connecting shaft 15 together with the upper support members 12A and 12A (see FIG. 6B).
　このように、下支持部材１２Ａ及び上支持部材１２Ｂは、回動自在であると共に、その材軸方向に伸縮自在に構成されているので、この回動と伸縮を組み合わせることで、両支持部材１２Ａ、１２Ｂに連結されている反射板１１は様々な形態の運動をすることができる。よって、反射板１１はスピーカユニット１Ｂに対して様々な位置形態で保持され得る。 As described above, the lower support member 12A and the upper support member 12B are configured to be rotatable and extendable in the direction of the material axis. , 12B can be moved in various forms. Therefore, the reflecting plate 11 can be held in various positions with respect to the speaker unit 1B.
　次に、図３（ａ）～（ｄ）に示す反射板１１の動作を詳細に説明する。反射板１１を図３（ａ）の状態にするには、図４（ａ）に示す初期状態から、例えば、下支持部材１２Ａ、１２Ａのアクチュエータ１３Ａ、１３Ａ及び上支持部材１２Ｂ、１２Ｂのアクチュエータ１３Ｂ、１３Ｂを同一長さ延ばすことで反射板１１を前方へ平行移動させて、下支持部材１２Ａ、１２Ａの正面側先端部が上昇するようにモータ１６を回転駆動させて、上支持部材１２Ｂ、１２Ｂ及び下支持部材１２Ａ、１２Ａを一体的に回転させる。この結果、反射板１１の下端部とパネル２の下端部とが鉛直方向において略同一位置になる。 Next, the operation of the reflector 11 shown in FIGS. 3A to 3D will be described in detail. In order to bring the reflector 11 into the state shown in FIG. 3A, for example, from the initial state shown in FIG. 4A, the actuators 13A and 13A of the lower support members 12A and 12A and the actuator 13B of the upper support members 12B and 12B are used. , 13B are extended by the same length to translate the reflector 11 forward, and the motor 16 is rotationally driven so that the front end portions of the lower support members 12A, 12A are raised, and the upper support members 12B, 12B And lower support member 12A, 12A is rotated integrally. As a result, the lower end portion of the reflecting plate 11 and the lower end portion of the panel 2 are substantially in the same position in the vertical direction.
　両アクチュエータ１３Ａ、１３Ｂの伸長と、両支持部材１２Ａ、１２Ｂの回転とを段階的に行う必要はなく、両支持部材１２Ａ、１２Ｂ及びアクチュエータ１３Ａ、１３Ｂの運動を同時に行うことも可能である。この場合、反射板１１の所望の位置への移動を迅速に行うことができるので、好適である。 It is not necessary to perform the extension of both actuators 13A and 13B and the rotation of both support members 12A and 12B in stages, and the movement of both support members 12A and 12B and actuators 13A and 13B can be performed simultaneously. In this case, it is preferable because the reflecting plate 11 can be quickly moved to a desired position.
　反射板１１を図３（ｂ）の状態にするには、図５（ａ）の初期状態から、例えば、上支持部材１２Ｂ、１２Ｂを同一長さ延ばすことで反射板１１を背面側から正面側へかけて上昇する傾斜状態にして、下支持部材１２Ａ、１２Ａが上昇するようにモータ１６を回転駆動させて、上支持部材１２Ｂ、１２Ｂ及び下支持部材１２Ａ、１２Ａを一体に回転させる。 In order to bring the reflecting plate 11 into the state of FIG. 3B, for example, the upper supporting members 12B and 12B are extended from the initial state of FIG. The motor 16 is rotationally driven so that the lower support members 12A and 12A are lifted, and the upper support members 12B and 12B and the lower support members 12A and 12A are rotated integrally.
　反射板１１を図３（ｃ）の状態にするには、図６（ａ）の初期状態から、例えば、下支持部材１２Ａ、１２Ａを同一長さ延ばすことで反射板１１を背面側から正面側へかけて下降する傾斜状態にして、下支持部材１２Ａ、１２Ａが下降するようにモータ１６を回転駆動させて、上支持部材１２Ｂ、１２Ｂ及び下支持部材１２Ａ、１２Ａを一体的に回転させる。 In order to bring the reflecting plate 11 into the state shown in FIG. 3C, for example, the lower supporting members 12A and 12A are extended by the same length from the initial state shown in FIG. The motor 16 is rotationally driven so that the lower support members 12A and 12A are lowered, and the upper support members 12B and 12B and the lower support members 12A and 12A are integrally rotated.
　反射板１１を図３（ｄ）の状態にするには、図７（ａ）の初期状態から、例えば、下支持部材１２Ａ、１２Ａ及び上支持部材１２Ｂ、１２Ｂを同一長さ延ばすことで、反射板１１を前方へ平行移動させる。このように、テレビ受像機Ｘの音声出力装置１は、コンテンツ信号を受けて反射板１１を可動させることによって、スピーカユニット１Ｂから出力される音の音響を変化させることが可能である。 In order to bring the reflector 11 into the state of FIG. 3D, the lower support members 12A and 12A and the upper support members 12B and 12B are extended from the initial state of FIG. The plate 11 is translated forward. Thus, the audio output device 1 of the television receiver X can change the sound of the sound output from the speaker unit 1B by moving the reflector 11 in response to the content signal.
　次に、テレビ受像機Ｘがコンテンツ信号としての放送信号Ｓ０を受けて反射板１１の可動を制御する方法を説明する。先ず、図８に基づいて、テレビ受像機Ｘの電気的な構成を説明する。制御装置２０は、中央処理装置（ＣＰＵ）、デジタルシグナルプロセッサ（ＤＳＰ）、シーケンサ等の演算手段を有し、記憶装置２３に記憶されているプログラムによる命令によって、その命令に基づいた処理を実行し、テレビ受像機Ｘを制御する。 Next, a method in which the television receiver X receives the broadcast signal S0 as the content signal and controls the movement of the reflector 11 will be described. First, the electrical configuration of the television receiver X will be described with reference to FIG. The control device 20 has arithmetic means such as a central processing unit (CPU), a digital signal processor (DSP), a sequencer, and the like, and executes processing based on the instructions according to the instructions stored in the storage device 23. The TV receiver X is controlled.
　記憶装置２３は、ＲＡＭやＲＯＭ、あるいはフラッシュメモリとの半導体メモリからなり、制御装置２０が実行するプログラムや、ユーザが操作装置２４を操作することにより読み込んだ情報等が記憶される。また、記憶装置２３は、制御装置２０が所定の処理を実行する際に作業用の記憶領域として使用される。 The storage device 23 includes a RAM, a ROM, or a semiconductor memory such as a flash memory, and stores a program executed by the control device 20, information read by the user operating the operation device 24, and the like. The storage device 23 is used as a work storage area when the control device 20 executes a predetermined process.
　操作装置２４は、例えば遠隔操作機器（リモコン：リモートコントローラー）、テレビ受像機Ｘの本体に設置された操作機器及び両操作機器から発信される信号を受信する受信部からなる。受信部は、例えば利用者が所望の事項を指示するために遠隔操作機器を操作する場合、遠隔操作機器からの赤外線パルスの操作信号（図示せず）を受信し、電気信号の操作信号Ｓ２に変換して制御装置２０に供給する。一方、利用者が本体に設置された操作機器を操作する場合、その操作に応じて受信部へ送信された電気信号を制御装置２０に操作信号Ｓ２として供給する。 The operation device 24 includes, for example, a remote operation device (remote controller: remote controller), an operation device installed in the main body of the television receiver X, and a receiving unit that receives signals transmitted from both operation devices. For example, when the user operates the remote control device in order to instruct a desired matter, the reception unit receives an infrared pulse operation signal (not shown) from the remote control device, and generates an electrical signal operation signal S2. The data is converted and supplied to the control device 20. On the other hand, when the user operates an operation device installed in the main body, an electric signal transmitted to the receiving unit in response to the operation is supplied to the control device 20 as an operation signal S2.
　チューナ２２は、アンテナ２１で受信された各種の放送信号Ｓ０の中から、利用者が操作装置２４を操作することによって選局したチャンネルの放送信号Ｓ０について、制御装置２０から供給される制御信号Ｓ１に基づいて、多重化されたトランスポートストリーム信号ＴＳへのデジタル復調処理及び誤り訂正処理を実行する。チューナ２２は、トランスポートストリーム信号ＴＳをデマルチプレクサ２５に送信する。 The tuner 22 uses the control signal S1 supplied from the control device 20 for the broadcast signal S0 of the channel selected by the user operating the operation device 24 from among the various broadcast signals S0 received by the antenna 21. Based on the above, digital demodulation processing and error correction processing are performed on the multiplexed transport stream signal TS. The tuner 22 transmits the transport stream signal TS to the demultiplexer 25.
　デマルチプレクサ２５は、制御装置２０から供給される制御信号Ｓ１に基づいて、チューナ２１から送信されたトランスポートストリーム信号ＴＳを、圧縮符号化された映像信号Ｓ４、音声信号Ｓ５及び番組情報信号Ｓ６等に分離、抽出して、映像信号Ｓ４及び音声信号Ｓ５をデコーダ２６へ、番組情報信号Ｓ６をＥＰＧ生成部２７へ送信する。 The demultiplexer 25 compresses and encodes the transport stream signal TS transmitted from the tuner 21 based on the control signal S1 supplied from the control device 20, the video signal S4, the audio signal S5, the program information signal S6, and the like. The video signal S4 and the audio signal S5 are transmitted to the decoder 26, and the program information signal S6 is transmitted to the EPG generation unit 27.
　デコーダ２６は、制御装置２０から供給される制御信号Ｓ１に基づいて、受信した映像信号Ｓ４を映像データＶＤに復号して、映像を表示部に出力するための映像出力部２８に送信すると共に、受信した音声信号Ｓ５を音声データＡＤに復号して、音声をスピーカユニット１Ｂから出力させるための音声出力部２９へ送信する。 The decoder 26 decodes the received video signal S4 into video data VD based on the control signal S1 supplied from the control device 20, and transmits the video data VD to the video output unit 28 for outputting the video to the display unit. The received audio signal S5 is decoded into audio data AD and transmitted to the audio output unit 29 for outputting audio from the speaker unit 1B.
　ＥＰＧ生成部２７は、制御装置２０から供給される制御信号Ｓ１に基づいて、番組情報信号Ｓ６を受信して、この番組情報信号Ｓ６が表す、番組のジャンルやチャンネル名等の番組に関する情報を、内部に設けられているＥＰＧ記憶領域２７Ａに記憶すると共に、この番組情報信号Ｓ６に対応するチャンネルについてＥＰＧを構築あるいは更新する。さらに、ＥＰＧ生成部２７は、番組情報信号Ｓ６が表す番組情報に含まれる番組のジャンル情報を抽出して、ジャンル情報を表すジャンル信号Ｓ７を制御装置２０に送信する。 The EPG generation unit 27 receives the program information signal S6 based on the control signal S1 supplied from the control device 20, and displays information related to the program such as the program genre and channel name represented by the program information signal S6. The EPG is stored in the EPG storage area 27A provided inside, and the EPG is constructed or updated for the channel corresponding to the program information signal S6. Further, the EPG generation unit 27 extracts the genre information of the program included in the program information represented by the program information signal S6, and transmits the genre signal S7 representing the genre information to the control device 20.
　また、ＥＰＧ生成部２７は、利用者が操作装置２４を操作することでＥＰＧのパネル２への表示を指示して、制御装置２０からその指示を表す制御信号Ｓ１が供給される場合には、ＥＰＧ記憶領域２７Ａに記憶されたＥＰＧに基づいて、パネル２にＥＰＧをＯＳＤ（Ｏｎ　Ｓｃｒｅｅｎ　Ｄｉｓｐｌａｙ）表示形式で表示するために必要なＥＰＧテーブル（ＥＰＧＴ）を生成して映像出力部２８に供給する。 Further, the EPG generation unit 27 instructs the display of the EPG on the panel 2 by the user operating the operation device 24, and when the control signal S1 representing the instruction is supplied from the control device 20, Based on the EPG stored in the EPG storage area 27A, an EPG table (EPGT) necessary for displaying the EPG in the OSD (On Screen Display) display format on the panel 2 is generated and supplied to the video output unit 28.
　制御装置２０は、ジャンル信号Ｓ７を受信することによって、反射板１１を可動させるアクチュエータ１３Ａ、１３Ｂ及びモータ１６からなる駆動装置を制御するための演算処理を実行する。このとき、駆動装置を制御する情報（以下、駆動制御情報という）を求め、この駆動制御情報を表す、アナログ信号又はデジタル信号からなる駆動制御信号Ｓ８を、アクチュエータ１３Ａ、１３Ｂ及びモータ１６に通信的に接続された駆動回路３０に送信する。駆動制御情報とは、アクチュエータ１３Ａ、１３Ｂ及びモータ１６に印加される電圧値に関する情報のことをいう。 The control device 20 receives the genre signal S7 and executes arithmetic processing for controlling the driving device including the actuators 13A and 13B that move the reflecting plate 11 and the motor 16. At this time, information for controlling the drive device (hereinafter referred to as drive control information) is obtained, and a drive control signal S8 composed of an analog signal or a digital signal representing the drive control information is communicated to the actuators 13A and 13B and the motor 16. To the drive circuit 30 connected to the. The drive control information refers to information regarding voltage values applied to the actuators 13A and 13B and the motor 16.
　駆動回路３０は、上側に配設されたアクチュエータ１３Ｂを駆動制御するための上アクチュエータ駆動回路３０Ａ、下側に配設されたアクチュエータ１３Ａを駆動制御するための下アクチュエータ回路３０Ｂ及びモータ１６を駆動制御するためのモータ駆動回路３０Ｃからなる。 The drive circuit 30 drives and controls the upper actuator drive circuit 30A for driving and controlling the actuator 13B disposed on the upper side, and the lower actuator circuit 30B and the motor 16 for driving and controlling the actuator 13A disposed on the lower side. The motor drive circuit 30C for this is comprised.
　駆動回路３０は、駆動制御信号Ｓ８が表す電圧値を制御用の電圧値に変換する。駆動回路３０は変換した制御用の電圧値の電圧を駆動装置に印加する。 The drive circuit 30 converts the voltage value represented by the drive control signal S8 into a control voltage value. The drive circuit 30 applies the voltage of the converted control voltage value to the drive device.
　制御装置２０は、例えばアクチュエータ１３Ａ、１３Ｂやモータ１６に実際に印加される電圧値の範囲が「０Ｖ～１５０Ｖ」である場合、一旦「０Ｖ～５Ｖ」の範囲に換算された電圧値（駆動制御情報）を表す、アナログ信号（又はデジタル信号）からなる駆動制御信号Ｓ８を駆動回路３０に出力する処理を行う。 For example, when the range of voltage values actually applied to the actuators 13A and 13B and the motor 16 is “0V to 150V”, the control device 20 once converts the voltage value (drive control) to the range of “0V to 5V”. A process of outputting a drive control signal S8 made up of an analog signal (or digital signal) representing information) to the drive circuit 30 is performed.
　この場合、駆動回路３０は、駆動制御信号Ｓ８が表す電圧値を、アクチュエータ１３Ａ、１３Ｂ及びモータ１６を稼動させるための実際の電圧値に変換し、駆動回路３０が構成する可変抵抗器（図示せず）を介して電圧をアクチュエータ１３Ａ、１３Ｂ及びモータ１６に印加する。 In this case, the drive circuit 30 converts the voltage value represented by the drive control signal S8 into an actual voltage value for operating the actuators 13A and 13B and the motor 16, and a variable resistor (not shown) configured by the drive circuit 30. The voltage is applied to the actuators 13A and 13B and the motor 16 via
　アクチュエータ１３Ａ、１３Ｂ及びモータ１６が駆動制御信号Ｓ８に応じて稼動することによって、反射板１１が可動するので、スピーカユニット１Ｂから出力された音の進む向きが変化し、音響が変更する。 When the actuators 13A and 13B and the motor 16 are operated according to the drive control signal S8, the reflector 11 is moved, so that the sound traveling direction output from the speaker unit 1B is changed, and the sound is changed.
　制御装置２０がジャンル信号Ｓ７を受信して駆動装置２０を制御するための演算処理を実行する際には、ジャンル信号Ｓ７が表すジャンル情報と音響制御情報（音響制御に係る情報）とが関連付けられたジャンル情報－音響制御テーブルを参照する（図９参照）。このジャンル情報－音響制御テーブルは予めＲＡＭに記憶されており、制御装置２０は受信したジャンル信号Ｓ７からジャンル情報を読み込んで、ジャンル情報に対応した音響制御情報を求め、音響制御情報に対応した駆動制御信号Ｓ８を駆動回路３０に送信する。 When the control device 20 receives the genre signal S7 and executes arithmetic processing for controlling the driving device 20, the genre information represented by the genre signal S7 and the acoustic control information (information related to acoustic control) are associated with each other. The genre information-acoustic control table is referred to (see FIG. 9). The genre information-acoustic control table is stored in advance in the RAM, and the control device 20 reads the genre information from the received genre signal S7, obtains the acoustic control information corresponding to the genre information, and drives corresponding to the acoustic control information. A control signal S8 is transmitted to the drive circuit 30.
　図９にジャンル情報－音響制御テーブルの具体例を示す。例えば、放送番組が分類されるジャンル情報として、ニュース等、映画・ドラマ等、スポーツ・音楽番組等及びコンサート・演劇等がある。そして、これらのジャンル情報に対応して、各ジャンルに適した音響制御情報が関連付けられており、ここでは音響制御情報は音響制御パターンによって「無（Ａ）」、「小（Ｂ）」、「中（Ｃ）」、「大（Ｄ）」に分けられている。「無」、「小」、「中」、「大」とは、音響の度合いを表現しているが、音響の度合いの代わりに、音響の度合いを達成するための反射板１１の動作等を用いることも可能である。 FIG. 9 shows a specific example of the genre information-acoustic control table. For example, genre information into which broadcast programs are classified includes news and the like, movies and dramas, sports and music programs, and concerts and plays. Corresponding to these genre information, acoustic control information suitable for each genre is associated. Here, the acoustic control information is “None (A)”, “Small (B)”, “ It is divided into “Medium (C)” and “Large (D)”. “None”, “small”, “medium”, and “large” express the degree of sound, but instead of the degree of sound, the operation of the reflector 11 to achieve the degree of sound, etc. It is also possible to use it.
　音楽制御情報は音響制御パターンを達成するための反射板１１の動作、すなわち駆動装置の駆動制御態様に関する情報（以下、駆動制御情報という）を有する。制御装置２０は、ジャンル情報を読み取って、ジャンル情報に基づく音響制御パターンに対応した、駆動装置を制御するプログラムを選択し、そのプログラムが起動することによって、駆動回路３０に駆動制御信号Ｓ８を送信する。 The music control information includes information regarding the operation of the reflector 11 for achieving the acoustic control pattern, that is, the drive control mode of the drive device (hereinafter referred to as drive control information). The control device 20 reads the genre information, selects a program for controlling the drive device corresponding to the acoustic control pattern based on the genre information, and transmits the drive control signal S8 to the drive circuit 30 when the program is activated. To do.
　続いて、制御装置２０の演算手段に反射装置１Ａの動作を制御させるプログラムの構成の具体例を図１０に示す。このプログラムは例えば、制御装置２０内に設けられているＲＯＭに記憶されている。メイン制御プログラムＰｍは、各プログラムＰ１～Ｐ５による命令を統括して制御するメインプログラムである。制御装置２０はメイン制御プログラムＰｍによって各プログラムＰ１～Ｐ５の命令による処理を実行する。 Subsequently, FIG. 10 shows a specific example of the configuration of a program for causing the calculation means of the control device 20 to control the operation of the reflection device 1A. For example, this program is stored in a ROM provided in the control device 20. The main control program Pm is a main program that controls the commands by the programs P1 to P5 in an integrated manner. The control device 20 executes processing according to instructions of the programs P1 to P5 by the main control program Pm.
　ジャンル信号入力プログラムＰ１は、ＥＰＧ生成部２７が送信したジャンル信号Ｓ７を読み込んでＲＡＭに一旦記憶する処理を行うプログラムである。 The genre signal input program P1 is a program that reads the genre signal S7 transmitted by the EPG generation unit 27 and temporarily stores it in the RAM.
　音響制御パターン選択プログラムＰ２は、ジャンル信号入力プログラムＰ２によって読み込まれたジャンル信号Ｓ７に基づいて、ジャンル情報－音響制御テーブルを参照して、ジャンル情報に対応する音響制御パターンを求め、ＲＡＭに記憶する処理を行うプログラムである。 The acoustic control pattern selection program P2 obtains an acoustic control pattern corresponding to the genre information by referring to the genre information-acoustic control table based on the genre signal S7 read by the genre signal input program P2, and stores it in the RAM. It is a program that performs processing.
　反射板制御プログラムＰ３は、反射板１１を可動させる駆動装置を稼動させるためのプログラムであり、ＲＡＭに記憶された音響制御パターンに対応した駆動制御信号Ｓ８を駆動回路３０に送信する。 The reflector control program P3 is a program for operating the drive device that moves the reflector 11, and transmits a drive control signal S8 corresponding to the acoustic control pattern stored in the RAM to the drive circuit 30.
　すなわち、反射板制御プログラムＰ３は、本実施の形態においては、反射板１１の可動態様に対応したスライドプログラムＰ３１、上プッシュプログラムＰ３２、下プッシュプログラムＰ３３及び両プッシュプログラムＰ３４で構成されるサブプログラムを有しており、ＲＡＭに記憶された音響制御パターンを読み取って、サブプログラムの中から音響制御パターンに対応したプログラムを選択する。選択されたサブプログラムＰ３１～Ｐ３４のいずれかは、ジャンル情報－音響制御テーブルを参照して、音響制御パターンに対応した駆動制御情報を求め、その駆動制御情報に対応した駆動制御信号Ｓ８を駆動回路３０に送信する。 That is, in the present embodiment, the reflector control program P3 is a subprogram composed of a slide program P31, an upper push program P32, a lower push program P33, and both push programs P34 corresponding to the movable mode of the reflector 11. And reading a sound control pattern stored in the RAM and selecting a program corresponding to the sound control pattern from the subprograms. Any of the selected subprograms P31 to P34 refers to the genre information-acoustic control table to obtain drive control information corresponding to the acoustic control pattern, and outputs a drive control signal S8 corresponding to the drive control information to the drive circuit. 30.
　例えば、図３（ａ）又は図４（ａ）～（ｃ）に示す例では、反射板制御プログラムＰ３によって、制御装置２０はジャンル信号Ｓ７に基づいて音響制御パターン「Ａ」を求め、スライドプログラムＰ３１を選択する。次いで、制御装置２０は、スライドプログラムＰ３１によって、音響制御パターン「Ａ」に対応する駆動制御情報を求め、アクチュエータ１３Ａ、１３Ｂを所定の長さ延ばすこと、及び、モータ１６を所定の角度回転させることを示す駆動制御信号Ｓ８を駆動回路３０に送信する（図９参照）。 For example, in the example shown in FIG. 3A or FIGS. 4A to 4C, the control device 20 obtains the acoustic control pattern “A” based on the genre signal S7 by the reflector control program P3, and the slide program Select P31. Next, the control device 20 obtains drive control information corresponding to the acoustic control pattern “A” by the slide program P31, extends the actuators 13A and 13B by a predetermined length, and rotates the motor 16 by a predetermined angle. Is transmitted to the drive circuit 30 (see FIG. 9).
　図３（ｂ）又は図５（ａ）～（ｃ）に示す例では、反射板制御プログラムＰ３によって、制御装置２０は、ジャンル信号Ｓ７に基づいて音響制御パターン「Ｂ」を求め、上プッシュプログラムＰ３２を選択する。次いで、制御装置２０は、上プッシュプログラムＰ３２によって、音響制御パターン「Ｂ」に対応する駆動制御情報を求め、アクチュエータ１３Ｂを所定の長さ延ばすこと、及び、モータ１６を所定の角度回転させることを示す駆動制御信号Ｓ８を駆動回路３０に送信する（図９参照）。 In the example shown in FIG. 3B or FIG. 5A to FIG. 5C, the control device 20 obtains the acoustic control pattern “B” based on the genre signal S7 by the reflector control program P3, and the upper push program Select P32. Next, the control device 20 obtains drive control information corresponding to the acoustic control pattern “B” by the upper push program P32, extends the actuator 13B by a predetermined length, and rotates the motor 16 by a predetermined angle. The drive control signal S8 shown is transmitted to the drive circuit 30 (see FIG. 9).
　図３（ｃ）又は図６（ａ）～（ｃ）に示す例では、反射板制御プログラムＰ３によって、制御装置２０は、ジャンル信号Ｓ７に基づいて音響制御パターン「Ｃ」を求め、下プッシュプログラムＰ３３を選択する。次いで、制御装置２０は、下プッシュプログラムＰ３３によって、音響制御パターン「Ｃ」に対応する駆動制御情報を求め、アクチュエータ１３Ａを所定の長さ延ばすこと、及び、モータ１６を所定の角度回転させることを示す駆動回路３０に送信する（図９参照）。 In the example shown in FIG. 3C or FIG. 6A to FIG. 6C, the control device 20 obtains the acoustic control pattern “C” based on the genre signal S7 by the reflector control program P3, and the lower push program Select P33. Next, the control device 20 obtains drive control information corresponding to the acoustic control pattern “C” by the lower push program P33, extends the actuator 13A by a predetermined length, and rotates the motor 16 by a predetermined angle. It transmits to the drive circuit 30 shown (refer FIG. 9).
　図３（ｄ）又は図６（ａ）～（ｃ）に示す例では、反射板制御プログラムＰ３によって、制御装置２０は、ジャンル信号Ｓ７に基づいて音響制御パターン「Ｄ」を求め、両プッシュプログラムＰ３４を選択する。次いで、制御装置２０は、両プッシュプログラムＰ３４によって、アクチュエータ１３Ａ、１３Ｂを所定の長さ延ばすことを示す駆動制御信号Ｓ８を駆動回路３０に送信する（図９参照）。 In the example shown in FIG. 3D or FIGS. 6A to 6C, the control device 20 obtains the acoustic control pattern “D” based on the genre signal S7 by the reflector control program P3, and both push programs Select P34. Next, the control device 20 transmits to the drive circuit 30 a drive control signal S8 indicating that the actuators 13A and 13B are extended by a predetermined length by both push programs P34 (see FIG. 9).
　ジャンル情報比較プログラムＰ４は、ＥＰＧ生成部２７のＥＰＧ記憶領域２７Ａに記憶されているジャンル情報と、ＥＰＧ生成部２７がジャンル信号Ｓ８を新たに受信することによって得られたジャンル情報とを比較する。両ジャンル情報を比較した結果、ジャンル情報が相違している場合に限り、その情報をＥＰＧ記憶領域２７Ａに読み込む（更新する）。これは、放送信号Ｓ０は一定間隔でテレビ受像機Ｘに送信されることから、受信される放送信号Ｓ０のチャンネルが変化されていないのであれば、放送信号Ｓ０が送信される都度、反射板１１を可動させる必要はないからである。 The genre information comparison program P4 compares the genre information stored in the EPG storage area 27A of the EPG generation unit 27 with the genre information obtained when the EPG generation unit 27 newly receives the genre signal S8. Only when the genre information is different as a result of comparing both genre information, the information is read (updated) into the EPG storage area 27A. This is because the broadcast signal S0 is transmitted to the television receiver X at regular intervals. Therefore, if the channel of the received broadcast signal S0 is not changed, the reflector 11 is transmitted each time the broadcast signal S0 is transmitted. It is because it is not necessary to move.
　初期状態プログラムＰ５は、ジャンル情報を新たにＥＰＧ記憶領域２７Ａに読み込んだときに、一旦反射板１１を初期状態に戻す処理を行うためのプログラムである。具体的には、反射板制御プログラムＰ３の各サブプログラムＰ３１～Ｐ３４によって実行される駆動装置の駆動態様と逆の態様で駆動装置を稼動させる。つまり、制御装置２０は、初期状態プログラムＰ５によって、選択されたサブプログラムＰ３１～Ｐ３４が求めた駆動制御情報とは逆の駆動態様を表す初期状態信号Ｓ９を駆動回路３０に送信する。 The initial state program P5 is a program for performing processing for temporarily returning the reflecting plate 11 to the initial state when genre information is newly read into the EPG storage area 27A. Specifically, the drive device is operated in a mode opposite to the drive mode of the drive device executed by the subprograms P31 to P34 of the reflector control program P3. That is, the control device 20 transmits to the drive circuit 30 an initial state signal S9 representing a driving mode opposite to the drive control information obtained by the selected subprograms P31 to P34 by the initial state program P5.
　続いて、制御装置２０が上記したプログラムにより、反射板１１の駆動を制御する手順の一例を、図１１に基づいて説明する。図１１は、制御装置２０がＥＰＧ生成部２７からジャンル信号Ｓ８を受信したときに、メイン制御プログラムＰｍが反射板１１の駆動を制御する手順を示すフローチャートである。 Subsequently, an example of a procedure in which the control device 20 controls the driving of the reflecting plate 11 by the above-described program will be described with reference to FIG. FIG. 11 is a flowchart illustrating a procedure in which the main control program Pm controls the driving of the reflecting plate 11 when the control device 20 receives the genre signal S8 from the EPG generation unit 27.
（ステップＳ１）
　ＥＰＧ生成部２７に送信されたジャンル信号Ｓ８を復号化して新たに読み取ったジャンル情報と、ＥＰＧ記憶領域２７Ａに記憶されているジャンル情報とが同一か否かを判定する。この判定の結果、両ジャンル情報が「同一」と判定されると、同判定を繰り返す。一方、両ジャンル情報が「相違」と判定されると、ステップＳ２に進む。 (Step S1)
It is determined whether or not the genre information newly decoded by decoding the genre signal S8 transmitted to the EPG generation unit 27 is the same as the genre information stored in the EPG storage area 27A. As a result of this determination, when it is determined that both genre information is “same”, the same determination is repeated. On the other hand, if it is determined that both genre information is “difference”, the process proceeds to step S2.
（ステップＳ２）
　駆動回路３０に初期状態信号Ｓ９を送信し、反射板１１を初期状態に戻す処理を行い、ステップＳ３に進む。 (Step S2)
An initial state signal S9 is transmitted to the drive circuit 30, a process for returning the reflector 11 to the initial state is performed, and the process proceeds to step S3.
（ステップＳ３）
　ジャンル情報－音響制御テーブルを参照して、新たに読み取ったジャンル情報に対応する音響制御パターンを求める処理を行い、ステップＳ４に進む。 (Step S3)
A process for obtaining an acoustic control pattern corresponding to the newly read genre information is performed with reference to the genre information-acoustic control table, and the process proceeds to step S4.
（ステップＳ４）
　求めた音響制御パターンに基づいて、いずれかのサブプログラムＰ３１～Ｐ３４を選択し、選択されたサブプログラムＰ３１～Ｐ３４に対応する駆動制御信号Ｓ８を駆動回路３０に送信し、ステップＳ５に進む。 (Step S4)
Based on the obtained acoustic control pattern, one of the subprograms P31 to P34 is selected, a drive control signal S8 corresponding to the selected subprograms P31 to P34 is transmitted to the drive circuit 30, and the process proceeds to step S5.
（ステップＳ５）
　駆動回路３０は、受信した駆動制御信号Ｓ８を、制御用の電圧値に変換し、その電圧値に基づいて駆動装置に電圧を印加する。この結果、駆動装置、すなわちアクチュエータ１３Ａ、１３Ｂ及びモータ１６が稼動するので、反射板１１が駆動する。その後、ステップＳ１の待機状態になる。 (Step S5)
The drive circuit 30 converts the received drive control signal S8 into a control voltage value, and applies a voltage to the drive device based on the voltage value. As a result, the driving device, that is, the actuators 13A and 13B and the motor 16 are operated, so that the reflecting plate 11 is driven. Then, it will be in the standby state of step S1.
