音声出力装置Audio output device
　本発明は、内部音源と外部音源とを切り替えることができる音声出力装置に関する。 The present invention relates to an audio output device capable of switching between an internal sound source and an external sound source.
　種々の音声出力装置は従来から開発されている。音声出力装置として、例えば、音声信号を増幅するアンプ及び当該アンプから出力される増幅音声信号に基づいて音声出力を行うスピーカを備えるスピーカ装置、音声出力のみならず映像出力も行うテレビジョン装置、電子楽器などを挙げることができる。 Various audio output devices have been developed. As an audio output device, for example, a speaker device including an amplifier that amplifies an audio signal and a speaker that outputs audio based on the amplified audio signal output from the amplifier, a television device that outputs video as well as audio, electronic You can list musical instruments.
　また、音声出力装置には、内部音源と外部音源とを切り替えることができるタイプのものがある（例えば特許文献１参照）。 Also, there is a type of audio output device that can switch between an internal sound source and an external sound source (see, for example, Patent Document 1).
特開平６－８３３３８号公報JP-A-6-83338 特開２００１―３４６１０１号公報Japanese Patent Laid-Open No. 2001-346101
　特許文献１で開示されている電子楽器は、操作性の向上を図るために、音色選択スイッチの１回の操作により、内部音源と外部音源との切り替えを可能にしている。しかしながら、内部音源と外部音源との切り替えを手動で切り替えていることに変わりはない。 The electronic musical instrument disclosed in Patent Document 1 enables switching between an internal sound source and an external sound source by a single operation of a timbre selection switch in order to improve operability. However, there is no change in manually switching between the internal sound source and the external sound source.
　電子楽器の演奏において演奏者が自己の意思で内部音源と外部音源との切り替えを行う場合などには、特許文献１のような手動での切り替えが適しているが、例えば、スピーカ装置やテレビジョン装置などでは、手動での切り替えは手間がかかるので好ましくない。 When the performer switches between an internal sound source and an external sound source with his / her own intention when playing an electronic musical instrument, manual switching as in Patent Document 1 is suitable. For example, a speaker device or a television is used. In an apparatus or the like, manual switching is not preferable because it takes time.
　例えば、音声出力装置において内部音源の出力があるときは外部音源よりも内部音源を優先して利用しようとする場合、内部音源の出力があるときに使用者が手動で内部音源に切り替える必要があり、非常に手間がかかる。 For example, when there is an internal sound source output in the audio output device, if the internal sound source is used in preference to the external sound source, the user must manually switch to the internal sound source when there is an internal sound source output. It takes a lot of work.
　なお、特許文献２には自動で入力切り替えを行う入力切り替え装置が開示されているが、特許文献２で開示されている入力切り替え装置は入力信号の有無に基づいて入力切り替えを行っているので、外部音源の音声信号も内部音源の音声信号も存在するときには、外部音源から内部音源への切り替えを自動で行うことができない。 Patent Document 2 discloses an input switching device that automatically performs input switching. However, since the input switching device disclosed in Patent Document 2 performs input switching based on the presence or absence of an input signal, When there are both an external sound source audio signal and an internal sound source audio signal, switching from the external sound source to the internal sound source cannot be performed automatically.
　本発明は、上記の状況に鑑み、外部音源から内部音源への切り替えに手間がかからない音声出力装置を提供することを目的とする。 In view of the above situation, an object of the present invention is to provide an audio output device that does not require time and effort to switch from an external sound source to an internal sound source.
　本発明に係る音声出力装置は、音声信号に基づいて音声出力を行う音声出力部と、音声データを含み得るコンテンツデータを再生するコンテンツ再生部と、前記コンテンツ再生部がコンテンツデータを再生しているときは、前記コンテンツ再生部の出力信号を選択して前記音声出力部に供給し、前記コンテンツ再生部がコンテンツデータを再生していないときは、外部入力信号を選択して前記音声出力部に供給する選択部とを備える構成とする。なお、前記選択部が前記コンテンツ再生部の出力信号を選択して前記音声出力部に供給する場合、前記コンテンツ再生部の出力信号の一部（映像音声信号の一部である音声信号）を選択して前記音声出力部に供給してもよい。 An audio output apparatus according to the present invention includes an audio output unit that outputs audio based on an audio signal, a content reproduction unit that reproduces content data that can include audio data, and the content reproduction unit that reproduces content data. When the content reproduction unit is not reproducing content data, the external input signal is selected and supplied to the audio output unit when the output signal of the content reproduction unit is selected and supplied to the audio output unit. And a selection unit to be configured. When the selection unit selects the output signal of the content reproduction unit and supplies it to the audio output unit, a part of the output signal of the content reproduction unit (an audio signal that is a part of the video / audio signal) is selected. And you may supply to the said audio | voice output part.
　本発明に係る音声出力装置によると、内部音源の出力があるときは自動的に内部音源に切り替わり、外部音源よりも内部音源が優先され、内部音源の出力に基づく音声出力が行われる。したがって、外部音源から内部音源への切り替えに手間がかからない。 The audio output device according to the present invention automatically switches to the internal sound source when the internal sound source is output, the internal sound source is prioritized over the external sound source, and the sound output based on the output of the internal sound source is performed. Therefore, it does not take time to switch from the external sound source to the internal sound source.

To do. The switching circuit 4 can also send the audio / video signal output from the tuner 1 or the external input signal from the external input terminal 2 to the optical disc recording / reproducing unit 3.
　信号処理回路５は、切替回路４から出力される信号に対して各種の信号処理を施して映像信号及び／又は音声信号を生成して出力する。信号処理回路５から出力される音声信号はアンプ６によって増幅され、スピーカ７によって音声に変換される。これにより、スピーカ７から音声が発せられる。表示部８は、信号処理回路５から出力される映像信号に応じた映像を表示画面に表示する。 The signal processing circuit 5 performs various kinds of signal processing on the signal output from the switching circuit 4 to generate and output a video signal and / or an audio signal. The audio signal output from the signal processing circuit 5 is amplified by the amplifier 6 and converted into audio by the speaker 7. Thereby, sound is emitted from the speaker 7. The display unit 8 displays a video corresponding to the video signal output from the signal processing circuit 5 on the display screen.
　ＣＰＵ９は、ユーザーによるキー操作を受け付ける本体操作部１２から出力される操作コマンドあるいはユーザーによるキー操作を受け付けるリモコン送信機４００から送信されるリモコン赤外線信号を受光するリモコン受光部１１から出力される操作コマンドに応じて、テレビジョン装置１００の各種制御を行う。メモリ１０は、ＣＰＵ９がテレビジョン装置１００の各種制御を行うために必要な各種プログラム及び各種データを不揮発的に記憶している。 The CPU 9 outputs an operation command output from the main body operation unit 12 that receives a key operation by the user or an operation command output from the remote control light receiving unit 11 that receives a remote control infrared signal transmitted from the remote control transmitter 400 that receives a key operation by the user. In response to this, various controls of the television device 100 are performed. The memory 10 stores various programs and various data necessary for the CPU 9 to perform various controls of the television device 100 in a nonvolatile manner.
　図２は、本実施形態に係る音声出力装置の一動作例を示すフローチャートである。本実施形態に係る音声出力装置（テレビジョン装置１００）が電源オン状態になったときに、図２に示すフローチャート動作が開始される。 FIG. 2 is a flowchart showing an operation example of the audio output device according to the present embodiment. When the audio output device (television device 100) according to the present embodiment is turned on, the flowchart operation shown in FIG. 2 is started.
　図２に示すフローチャート動作が開始されると、まず始めにＣＰＵ９は、光ディスク記録再生部３がコンテンツデータを再生しているか否かを判定する（ステップＳ１０）。 2 is started, first, the CPU 9 determines whether or not the optical disc recording / reproducing unit 3 is reproducing content data (step S10).
　光ディスク記録再生部３がコンテンツデータを再生していれば（ステップＳ１０のＹＥＳ）、ＣＰＵ９の制御に従って、切替回路４は光ディスク記録再生部３の出力信号を選択して信号処理回路５に供給し（ステップ２０）、その後ステップＳ４０に移行する。 If the optical disc recording / reproducing unit 3 is reproducing the content data (YES in step S10), the switching circuit 4 selects the output signal of the optical disc recording / reproducing unit 3 and supplies it to the signal processing circuit 5 according to the control of the CPU 9 ( Step 20), and then the process proceeds to step S40.
　光ディスク記録再生部３がコンテンツデータを再生していなければ（ステップＳ１０のＮＯ）、ＣＰＵ９の制御に従って、切替回路４はチューナ１から出力される映像音声信号（外部入力信号）又は外部入力端子２からの外部入力信号を選択して信号処理回路５に供給し（ステップ３０）、その後ステップＳ４０に移行する。 If the optical disc recording / reproducing unit 3 is not reproducing the content data (NO in step S10), the switching circuit 4 is controlled by the video / audio signal (external input signal) output from the tuner 1 or the external input terminal 2 according to the control of the CPU 9. The external input signal is selected and supplied to the signal processing circuit 5 (step 30), and then the process proceeds to step S40.
　ステップＳ４０において、スピーカ７はアンプ６から供給される音声信号（増幅音声信号）に基づいて音声出力を行い、その後ステップＳ１０に戻る。 In step S40, the speaker 7 performs audio output based on the audio signal (amplified audio signal) supplied from the amplifier 6, and then returns to step S10.
　このような構成によると、光ディスク記録再生部３がコンテンツデータを再生しているとき、すなわち内部音源の出力があると想定されるときは、切替回路４が光ディスク記録再生部３の出力信号を選択して信号処理回路５に供給するので、自動的に内部音源に切り替わり、外部音源よりも内部音源が優先され、スピーカ７において内部音源の出力に基づく音声出力が行われる。したがって、外部音源から内部音源への切り替えに手間がかからない。 According to such a configuration, when the optical disc recording / reproducing unit 3 is reproducing the content data, that is, when there is an output of the internal sound source, the switching circuit 4 selects the output signal of the optical disc recording / reproducing unit 3 Therefore, the signal is automatically switched to the internal sound source, the internal sound source is prioritized over the external sound source, and the speaker 7 performs sound output based on the output of the internal sound source. Therefore, it does not take time to switch from the external sound source to the internal sound source.
　ただし、光ディスク記録再生部３がコンテンツデータを再生しているときに必ず内部音源の出力があるわけではない。光ディスク記録再生部３が音声データを含まないコンテンツデータ（例えば静止画像データ）を再生している場合には、光ディスク記録再生部３がコンテンツデータを再生しているにもかかわらず内部音源の出力がない状態となる。 However, when the optical disc recording / reproducing unit 3 is reproducing the content data, the internal sound source is not always output. When the optical disc recording / reproducing unit 3 reproduces content data (for example, still image data) that does not include audio data, the output of the internal sound source is output even though the optical disc recording / reproducing unit 3 reproduces the content data. No state.
　そこで、例えば図３に示すように、ステップ１０とステップＳ２０との間にステップＳ１５を設け、光ディスク記録再生部３がコンテンツデータを再生していれば（ステップＳ１０のＹＥＳ）、光ディスク記録再生部３によって再生されているコンテンツデータに音声データが含まれているか否かをＣＰＵ９が判定するようにし（ステップＳ１５）、光ディスク記録再生部３によって再生されているコンテンツデータに音声データが含まれていれば（ステップＳ１５のＹＥＳ）、ステップＳ２０へ進み、光ディスク記録再生部３によって再生されているコンテンツデータに音声データが含まれていなければ（ステップＳ１５のＮＯ）、ステップＳ３０へ進むようにすればよい。 Therefore, for example, as shown in FIG. 3, if step S15 is provided between step 10 and step S20 and the optical disc recording / playback unit 3 plays back content data (YES in step S10), the optical disc recording / playback unit 3 The CPU 9 determines whether or not the audio data is included in the content data being reproduced by (step S15), and if the audio data is included in the content data being reproduced by the optical disc recording / reproducing unit 3 (YES in step S15), the process proceeds to step S20. If the audio data is not included in the content data reproduced by the optical disc recording / reproducing unit 3 (NO in step S15), the process may proceed to step S30.
　図３に示すフローチャート動作によると、音声データが含まれていないコンテンツデータの再生と、外部音源の出力に基づく音声出力とを両立させた利用形態が可能となり、利便性が向上する。この場合、切替回路４を音声信号専用の切替回路と映像信号専用の切替回路とを設け、音声信号専用の切替回路の切り替えと映像信号専用の切替回路の切り替えとが独立して制御されるようにすればよい。 According to the flowchart operation shown in FIG. 3, it is possible to achieve a usage mode in which playback of content data not including audio data and audio output based on the output of an external sound source are compatible, and convenience is improved. In this case, the switching circuit 4 is provided with a switching circuit dedicated to the audio signal and a switching circuit dedicated to the video signal so that switching of the switching circuit dedicated to the audio signal and switching of the switching circuit dedicated to the video signal are controlled independently. You can do it.

　ＣＰＵ２６がコンテンツデータを再生していれば（ステップＳ１０のＹＥＳ）、ＣＰＵ２６の制御に従って、切替回路２３はＣＰＵ２６の出力信号を選択してアンプ２４に供給し（ステップ２０）、その後ステップＳ４０に移行する。 If the CPU 26 is reproducing the content data (YES in step S10), the switching circuit 23 selects the output signal of the CPU 26 and supplies it to the amplifier 24 (step 20) according to the control of the CPU 26, and then proceeds to step S40. .

　このような構成によると、ＣＰＵ２６がコンテンツデータを再生しているとき、すなわち内部音源の出力があると想定されるときは、切替回路２３がＣＰＵ２６の出力信号を選択してアンプ２４に供給するので、自動的に内部音源に切り替わり、外部音源よりも内部音源が優先され、スピーカ２５において内部音源の出力に基づく音声出力が行われる。したがって、外部音源から内部音源への切り替えに手間がかからない。 According to such a configuration, when the CPU 26 is reproducing the content data, that is, when there is an output of the internal sound source, the switching circuit 23 selects the output signal of the CPU 26 and supplies it to the amplifier 24.
