As a result, the AV amplifier 1 can provide a good sound reproduction environment (sound field) to the user. When the AV amplifier 1 detects a speaker that does not respond as a result of the measurement, or a speaker having extremely different characteristics from other speakers, the AV amplifier 1 may stop using the speaker. As a result, the AV amplifier 1 can avoid the necessary sound from being output from the speaker 2 by allocating a signal to such a speaker.
- the control unit 105 determines whether there is a change in the installation position of the speaker 2 with respect to the AV amplifier 1 (step S107).
- the change of the installation position of 2 is detected. Whether or not there is a change in the installation position of the speaker 2 with respect to the AV amplifier 1 in the control unit 105 may be determined by referring to the value of the movement flag associated with each speaker 2. For example, the control unit 105 determines that the installation position of the speaker 2 corresponding to the movement flag whose value is set to “1” has been changed, and corresponds to the movement flag whose value is set to “0”. What is necessary is just to determine with the speaker 2 to perform that the installation position is not changed.
- step S107 If it is determined that the installation position of the speaker 2 has been changed (YES in step S107), the control unit 105 determines that “the speaker has been moved. A message prompting to start the measurement of the speaker installation position, such as “Do you want to measure?” Is displayed on the screen of the television 6 (step S108).
- control unit 105 executes the processes of steps S104 to S106.
- step S104 When a speaker position measurement start instruction is not input after the message is displayed (NO in step S104), after the speaker position measurement process (step S106) is executed, or when the installation position of the speaker 2 is not changed (NO in step S107), the acoustic system 10 performs a normal operation.
- a movement flag may be associated with each of the plurality of speakers 2, or a single movement flag may be associated with the plurality of speakers 2.
- the control unit 105 performs the speaker position measurement process only for the speaker 2 corresponding to the movement flag whose value is set to “1”. The time required for the processing can be shortened.
- the AV amplifier 1 updates the installation position of the speaker 2 by measuring the current installation position of the speaker 2 whose installation position has changed as described above, and reflects it in the audio signal adjustment processing in the audio processing unit 102. As a result, it is possible to maintain a favorable sound reproduction environment.
- the sensor 202 When the sensor 202 detects that the speaker 2 has been moved, the sensor 202 notifies the control unit 105 of a sensor signal indicating that the installation position of the speaker 2 has been moved.
- the control unit 105 acquires the sensor signal from the sensor 202 of the speaker 2, the position of the speaker 2 is moved by setting the value of the movement flag corresponding to the moved speaker 2 from “0” to “1”. Record what has been done.
- the sensor 202 of the speaker 2 detects whether or not the own apparatus has moved during a period when the AV amplifier 1 is not activated (the power is OFF), and the detection result is sent to a recording unit (not shown) of the speaker 2. It may be recorded (for example, when movement is detected, the value of the movement flag of the recording unit may be set from “0” to “1”).

- the delay time due to other factors other than the time during which the sound propagates through the space can be considered, it is preferable to consider in advance the addition of the delay time due to the other factors. Further, since the sound speed varies depending on the temperature, it is more preferable to provide a temperature sensor to correct the sound speed.
- the measurement unit 106 analyzes each signal from the plurality of microphone units 301 built in the microphone 3 and obtains a delay time. As described above, since each microphone unit 301 has a spatially dispersed arrangement, the distance between each microphone unit 301 and the speaker 2 can be obtained. Thereby, the measurement unit 106 can obtain the relative position of the speaker 2 with respect to the microphone 3 and can obtain the installation position of the speaker 2.

Do not measure position. Therefore, the AV amplifier 1 can prevent omission of the measurement of the position of the speaker 2 when the position of the speaker 2 changes, and can prevent the position of the speaker 2 from being measured more than necessary.
- the measurement of the position of the speaker 2 requires the reproduction of the measurement audio signal, and further, the measurement requires a certain amount of time. If measurement of the position 2 is required, the user is stressed. In addition, when measuring the position of the speaker 2, the user must reproduce the measurement sound. During the measurement, the user cannot reproduce the sound desired by the user. There are many restrictions, such as the need to avoid building up. However, as described above, since the AV amplifier 1 does not measure the position of the speaker 2 more than necessary, it is possible to reduce such stress on the user.

Abstract
Description
以下、本発明の一実施形態について、詳細に説明する。但し、この実施形態に記載されている構成は、特に特定的な記載がない限り、この発明の範囲をそれのみに限定する趣旨ではなく、単なる説明例に過ぎない。
まず、本実施形態に係る音響システム10の構成の概要について、図1を参照して説明する。図1は、本実施形態に係る音響システム10の構成の概要を示すブロック図である。図1に示すように、本実施形態に係る音響システム10は、AVアンプ1(音響装置)、スピーカ2(スピーカ機器)、マイク3、再生装置5、及び、テレビ6を備えている。
次に、本実施形態に係るAVアンプ1の構成について説明する。AVアンプ1は、複数のスピーカ2の各々に音声信号を供給する音響装置として機能する。また、AVアンプ1は、図1に示すように、入出力部101、音声処理部102(調整部)、増幅部103、操作部104、制御部105(検知部)、及び、測定部106(検知部)を備えている。
ここで、本実施形態に係るマイク3の構成について、図2を参照して説明する。図2は、本実施形態に係るマイク3の構成を模式的に示す図である。図2(a)は、マイク3の備えるマイクユニット301の斜視図であり、(b)は正面図(X軸正方向から見た図)であり、(c)は上面図(Z軸正方向から見た図)であり、(d)は右側面図(Y軸負方向から見た図)である。
次に、音響システム10全体の処理(動作)について、図3を参照して説明する。図3は、本実施形態に係る音響システム10における処理の流れを示すフローチャートである。
音響システム10の使用を終えると、ユーザは、AVアンプ1にスピーカ2、マイク3、再生装置5、及びテレビ6などを接続したままで、音響システム10の電源を切る(以降では、電源をOFFにする、とも記載する)。このとき、AVアンプ1の制御部105及び操作部104は、その一部の機能を起動させたまま(すなわち、待機モード)、ユーザの操作を待つ。また、制御部105は、増幅部103を経由してスピーカ2に内蔵されたセンサ202との通信を継続する。なお、本実施形態において、音響システム10の電源を切るとは、例えば、AVアンプ1又はテレビ6などの電源をOFFすることにより、連動して音響システム10に含まれる他の機器の電源をOFFにすることを指すが、もちろん、各機器の電源をそれぞれ独立してOFFにしてもよい。
次に、音響システム10におけるスピーカ位置測定処理について説明する。
次に、本発明の他の実施形態について、図4から図7を参照して説明する。図4は、本実施形態の音響システム20の構成の概要を模式的に示す外観図である。図4に示すように、本実施形態に係る音響システム20は、再生装置5、テレビ7(音響装置、テレビジョン受像機)、及び、複数の無線スピーカ8(スピーカ機器)を備えている。
本実施形態に係るテレビ7の構成について、図5を参照して説明する。図5は、本実施形態に係るテレビ7の構成の概要を示すブロック図である。
次に、本実施形態に係る無線スピーカ8の構成について、図6を参照して説明する。図6は、本実施形態に係る無線スピーカ8の構成の概要を示すブロック図である。
次に、音響システム20全体の処理(動作)について、図7を参照して説明する。図7は、本実施形態に係る音響システム20における処理の流れを示すフローチャートである。
ユーザは操作部707を操作して、テレビ7の電源をOFFにする操作を行う。操作部707からの信号を受け付けると、制御部708は、テレビ7の各部に電源断の指示を出すとともに、無線通信部711を経由して無線スピーカ8に対しても電源断の指示を出力する。なお、無線通信部711は、無線スピーカ8に対しても電源断の指示を出力した後に電源断となることが好ましい。
次に、ユーザがテレビ7を視聴中に無線スピーカ8を移動した場合、及び、及び電源断の状態で無線スピーカ8を移動させ、起動後に測定を行わなかった場合の処理について説明する。
AVアンプ1の各ブロック(特に、制御部105、測定部106、音声処理部102)、テレビ7の制御部の各ブロック(特に、制御部708、測定部709、音声処理部702)、並びに、無線スピーカ8の各ブロック(特に、制御部806、音声処理部802)などは、集積回路(ICチップ)等に形成された論理回路(ハードウェア)によって実現してもよいし、CPU(Central Processing Unit)を用いてソフトウェアによって実現してもよい。
