ここで、所望の報知音を録音する方法について説明する。一般に、スピーカ本体１０は天井や壁面などの高所に設置されて使用されるので、報知音を録音する際には取付ベース２３からケース２０を取り外し、録音作業のやり易い場所に移動させて録音を行う。なお、ケース２０を取付ベース２３から取り外して使用する際は、主電源部１８と回路基板２６との間を接続するケーブル２７を外し、ケース２０の後面側に設けた電池ボックス２９に電池Ｂを取り付け、電池Ｂを電源として動作させる。
【００２９】
報知音を録音する際には、先ずモード切替スイッチＳ１の操作摘み３１を下側の切換位置にスライドさせて動作モードを録音モードに切り替える。尚、上述のように発光ダイオードＬＤ２は動作モードに応じて発光色が変化し、通常モードでは赤色、再生モードではオレンジ色、録音モードでは緑色で点灯する。
【００３０】
ここで、録再回路１３に音声信号を入力する方法としては、内蔵のマイクＭＣ１で音声を電気信号に変換して入力する方法、外部マイクからの音声信号をマイク入力部ＭＣ２を介して入力する方法、ＡＶ機器からの音声信号をライン入力部ＡＶＸを介して入力する方法の３通りの方法がある。マイク入力部ＭＣ２又はライン入力部ＡＶＸにプラグが接続されていなければ、内蔵のマイクＭＣ１からの音声信号が録再回路１３に入力される。一方、マイク入力部ＭＣ２又はライン入力部ＡＶＸにプラグが接続されると、マイクＭＣ１からの入力が自動的に切り離されて、外部マイク又はＡＶ機器からの音声信号がマイク入力部ＭＣ２又はライン入力部ＡＶＸを通じて録再回路１３に自動的に入力され、さらに入力された音声信号がスピーカＳＰから出力されるようになっている。
【００３１】
動作モードが録音モードに切り替えられると、録再回路１３に内蔵されたレベルメータ（図示せず）が動作を開始し、入力信号の信号レベルを検出して、発光ダイオードＬＤ３の表示色で信号レベルを表示するようになっている。発光ダイオードＬＤ３は、入力信号の音量が小さい場合は黄色、最適であれば緑色、大きい場合は赤色で点灯するようになっており、入力信号の音量の大小を視覚的に確認することができる。而してユーザが、上述した３通りの方法の何れかで録音したい音（音声メッセージやメロディ音など）を入力して、発光ダイオードＬＤ３の発光色を見ながら、入力信号の音量を調整して録音レベルを最適値に設定した後、リモコン設定器５０の操作キーＫ５〜Ｋ１２により録音したいボックス番号を入力すると、制御部５１が送信部５３からボックス番号を示す信号を送信させる。この時、スピーカ本体１０の受信部１５がリモコン設定器５０から送信された信号を受信し、制御部１１が受信信号に基づいて発光ダイオードＬＤ２を１秒周期で５秒間緑色で点滅させた後、発光ダイオードＬＤ２を緑色点灯させるとともに、録再回路１３の録音動作を開始させる。その後、ユーザがリモコン設定器５０の操作キーＫ０を押操作すると、制御部５１は送信部５３から録音動作を終了させる信号を送信させ、スピーカ本体１０では受信部１５がこの信号を受信して、制御部１１が録再回路１３の録音動作を終了させ、音声メモリ１４の指定されたボックスに音声信号を記録させる。
【００３２】
ここで、発光ダイオードＬＤ２の点滅中に別のボックス番号に対応した操作キーＫ５〜Ｋ１２が押操作された場合は、後に押された操作キーＫ５〜Ｋ１２を優先して、キー操作に応じてリモコン送信器５０から送信された信号を受信した時点から５秒間、制御部１１が発光ダイオードＬＤ２を点滅させた後、後に押された操作キーで指定されたボックスに、入力された音声信号を録音させる。また、発光ダイオードＬＤ２が点灯状態に切り替わった後に何れかの操作キーＫ５〜Ｋ１２が押された場合、そのキー入力は無視する。なお、各ボックスに録音可能な音声信号の時間（録音可能時間）は予め決められており、録音動作を開始してからリモコン設定器５０の操作キーＫ０が押されるまでの間にこのボックスに録音可能な時間が経過すると、制御部１１は録再回路１３の録音動作を終了させるとともに、スピーカＳＰから警告音を出力させる。
【００３３】
ところで、録音するボックスを指定する際に操作キーＫ０〜Ｋ４が押された場合、０番及び１番〜４番までのボックスは固定音用であり、ユーザ側で録音できないため、制御部１１は録再回路１３を用いてスピーカＳＰから警告音を出力させる。また、録音モードに切り換えられた状態で数字を表す操作キーＫ０〜Ｋ１２以外のキーが押操作された場合にはその入力を無視し、録再回路１３を用いてスピーカＳＰから警告音を出力させる。またリモコン設定器５０には、ユーザ側で録音可能な５番から１２番までのブロック（記憶ブロック）の録音内容を消去するキーが用意されておらず、先に録音した音声信号を消去したい場合はそのブロックに上書きすることで音声信号を消去すれば良い。
【００３４】
上述のように本実施形態の人体検知機能付スピーカ装置は所望の報知音を録音する機能を有し、この録音機能を利用してお店の雰囲気に合わせた音声や音楽、建物内の案内用の音声、警戒監視用の音声などをスピーカ６から出力させることも可能であり、多用途に展開でき、設置場所も建物の出入口だけでなく、建物内に設定することや屋外で設置することも可能である。なお、メーカ側で想定される使用状況に合わせた音声メッセージ（日本語および外国語による挨拶や警告）、効果音（小鳥のさえずりや波の音といった自然の音や鈴、鐘の音など）、メロディ音、警報音及び呼出音を録音したコンパクトディスクを用意し、このコンパクトディスクを出荷時に添付しておけば、このコンパクトディスクに録音された音をコンパクトディスクプレイヤーで再生し、ライン入力部ＡＶＸを通じて録再回路１３に入力させることで、コンパクトディスクに録音された音の中から所望の音を報知音として録音させることができ、汎用性が高くなる。
【００３５】
また、このスピーカ本体１０は天井や壁面などの造営面に設置されて使用されるため、頻繁に行う設定操作を本体側で行うのは困難であるから、リモコン設定器５０を用いて各種の設定操作を行うようにしている。
【００３６】
ここで、リモコン設定器５０を用いて、音声メモリ１４の１２個のボックスに登録された報知音の中から人体検知時に再生させる報知音の組合せを選択する方法について説明する。本実施形態では、人体が方向Ｄ１に移動する時の報知音と方向Ｄ２に移動する時の報知音とを１つの組（パターン）として複数パターン（本実施形態では例えば２パターン）選択できるようになっており、２つのパターンをそれぞれパターンＰ１、パターンＰ２と呼ぶ。
【００３７】
例えばパターンＰ１の方向Ｄ１における報知音として７番のボックスに録音された報知音を選択する場合、ケース２０を取付ベース２３に取り付けている状態でリモコン設定器５０の操作キーＫ３１を押すと、送信部５３から動作モードを通常モードに切り替える信号が送信され、この信号を受けてスピーカ本体１０の制御部１１が動作モードを通常モードに切り替えるとともに、発光ダイオードＬＤ２を赤色で点灯させる。その後、リモコン設定器５０の操作キーＫ２１を押すと、送信部５３からパターンＰ１の方向Ｄ１を指定する信号が送信され、この信号を受けてスピーカ本体１０の制御部１１は内部タイマ（図示せず）のカウント動作を開始させる。そして、内部タイマによるカウント時間（例えば５秒）のカウント動作が終了するまでの間に、選択するボックス番号（７番）に対応した操作キー（Ｋ７）が押されると、送信部５３から７番のボックス番号を指定する信号が送信され、この信号を受けてスピーカ本体１０の制御部１１は内部タイマのカウント動作をリセットして再度開始させる。その後、内部タイマによるカウント時間（例えば５秒）のカウント動作が終了するまでの間に、リモコン設定器５０の操作キーＫ３７が押されると、送信部５３から報知音を登録する信号が送信され、この信号を受けて設定手段たるスピーカ本体１０の制御部１１は指定されたボックスに録音された報知音をスピーカＳＰから出力させるとともに、この報知音をパターンＰ１の方向Ｄ１における報知音として設定する。ここで、制御部１１の内部タイマがカウント動作を終了するまでの間にリモコン設定器５０からの信号送信がなければ、報知音の選択処理を終了する。また、指定されたボックスに報知音が録音されていない場合や０番のボックスが指定された場合には報知音が無音になり、その方向に移動する人を検知しても報知音が出力されなくなる。なお、他の報知音についても上述と同様の手順で選択することができる。表２及び表３は報知音の設定例を示しており、表２に示す例ではパターンＰ１が選択されている場合に方向Ｄ１に人体が移動していれば報知音ａを、方向Ｄ２に人体が移動していれば報知音ｂを出力させ、パターンＰ２が選択されている場合に方向Ｄ１に人体が移動していれば報知音ｃを、方向Ｄ２に人体が移動していれば報知音ｄを出力させる。
【００３８】
【表２】

【００３９】
【表３】

【００４０】
上述のようにして音声メモリ１４に設けた複数のボックスに所望の報知音を録音し、パターンＰ１，Ｐ２の方向Ｄ１，Ｄ２における報知音として、各ボックスに録音された報知音を選択できるのであるが、リモコン設定器５０の操作キーＫ３３を用いて出力パターンをパターンＰ１とパターンＰ２とに交互に切り替えることができる。リモコン設定器５０の操作キーＫ３３を押すと、制御部５１は送信部５３から出力パターンを反転させる信号を送信させる。この信号をスピーカ本体１０の受信部１５が受信すると、制御部１１が、受信部１５の受信した信号に基づいて再生する報知音の出力パターンをパターンＰ１又はＰ２に交互に切り替えており、方向Ｄ１及び方向Ｄ２の報知音を１セットで切り替えることができる。尚、リモコン設定器５０の操作キーＫ３３を用いる代わりに、スピーカ本体１０のパターン切替スイッチＳ２を用いてパターンを切り替えることもでき、パターン切替スイッチＳ２の操作釦３２を押す毎にパターンＰ１又はＰ２に交互に切り替えることができる。
【００４１】
また更に、スピーカ本体１０の設定状態をリモコン設定器５０の操作キーＫ３６を用いて確認することができる。設定確認時には、先ずリモコン設定器５０の操作キーＫ３１を押して、リモコン設定器５０から再生モードに切り替える信号を送信させる。スピーカ本体１０では、この信号を受けて制御部１１が動作モードを再生モードに切り替えるとともに、発光ダイオードＬＤ２をオレンジ色で発光させる。この状態でリモコン設定器５０の操作キーＫ３６（第１の操作手段）を押すと、制御部５１は送信部５３から設定状態を確認する設定確認信号を送信させる。この設定確認信号をスピーカ本体１０の受信部１５が受信すると、制御部１１が、録再回路１３を制御し、「現在の動作環境の確認をします」という音声メッセージに続けて、方向Ｄ１のときの報知音と、方向Ｄ２のときの報知音とをスピーカＳＰから出力させ、さらに連続鳴動機能がオンの場合は「連続鳴動オンです」、オフの場合は「連続鳴動オフです」という音声メッセージをスピーカＳＰから出力させる。なお、方向Ｄ１又はＤ２の報知音として無音が設定されている場合には、録再回路１３は「無音です」というメッセージをスピーカＳＰから出力させている。そして、設定状態を確認した後にリモコン設定器５０の操作キーＫ３１を押すと、リモコン設定器５０から通常モードに切り替える信号が送信され、この信号を受けてスピーカ本体１０の制御部１１が動作モードを通常モードに切り替える。このように、リモコン設定器５０を用いて現在の報知音の設定を確認することができるので、スピーカ本体１０が天井や壁面などの高所に設置されている場合でも確認作業を容易に行うことができる。
【００４２】
また、リモコン設定器５０を用いて各ブロックに録音されている報知音を実際に鳴動させて確認することもできる。ケース２０が取付ベース２３に保持されている場合は、モード切替スイッチＳ１により動作モードを通常モードに切り替えた後、リモコン設定器５０の操作キーＫ３１を押すと、リモコン設定器５０から再生モードに切り替える信号が送信され、この信号を受けてスピーカ本体１０の制御部１１が動作モードを再生モードに切り替えるとともに、発光ダイオードＬＤ２をオレンジ色で発光させる。また、ケース２０を取付ベース２３から取り外して電池駆動させた場合には、スピーカ本体１０の動作モードが自動的に再生モードに切り替えられる。このようにスピーカ本体１０の動作モードを再生モードに切り替えられた状態で、リモコン設定器５０の何れかの操作キーＫ１〜Ｋ１２（第２の操作手段）を押操作すると対応するブロック番号の報知音を再生させる報知音再生信号が送信部５３から送信される。この報知音再生信号をスピーカ本体１０の受信部１５が受信すると、制御部１１が録再回路１３を用いて指定された登録番号の報知音を再生させ、スピーカＳＰから出力させており、各ブロックに録音されている音声信号の内容をリモコン設定器５０を用いて確認することができる。そして、設定状態を確認した後にリモコン設定器５０の操作キーＫ３１を押すと、リモコン設定器５０から通常モードに切り替える信号が送信され、この信号を受けてスピーカ本体１０の制御部１１が動作モードを通常モードに切り替える。なお、リモコン設定器５０の背面に図１３に示すようなシール６１を貼り付けて、１〜１２番のボックスに録音された音の種類を表示することにより、目で見て確認できるようにしても良い。
【００４３】
また、リモコン設定器５０の操作キーＫ３２により連続鳴動機能をオン／オフすることができる。操作キーＫ３２を押操作すると、リモコン設定器５０から連続鳴動機能をオン又はオフさせる信号が送信され、この信号を受けてスピーカ本体１０の制御部１１が連続鳴動機能をオン又はオフする。ここに、連続鳴動機能がオフされると、人体を１度検知して報知音を出力した場合、一定時間内（例えば約２０秒以内）は報知音を出力しなくなるので、複数の人間が連続して出入りする場合や人が立ち止まった場合に報知音が鳴り続けるのを防止できる。
【００４４】
また、リモコン設定器５０の操作キーＫ３４，Ｋ３５又はスピーカ本体１０のスイッチＳ３，Ｓ４を用いてスピーカＳＰの音量を変化させることができる。スピーカＳＰの音量は無音状態を含めて７段階に切り替えることができる。動作モードが通常モードに設定されている状態で、操作キーＫ３４又はスイッチＳ３を１回押操作すると、録再回路１３は１段階大きな音量で現在選択されているパターンの両方向の報知音をスピーカＳＰから出力させ、操作キーＫ３５又はスイッチＳ４を１回押操作すると、録再回路１３は１段階小さな音量で現在選択されているパターンの両方向の報知音をスピーカＳＰから出力させる。一方、動作モードが再生モードに設定されている状態で、操作キーＫ３４又はスイッチＳ３を１回押操作すると、録再回路１３は最後に出力した報知音を１段階大きな音量でスピーカＳＰから出力させ、操作キーＫ３５又はスイッチＳ４を１回押操作すると、録再回路１３は最後に出力した報知音を１段階小さな音量でスピーカＳＰから出力させる。なお、スピーカＳＰの音量の最大値は、ユーザが録音した報知音を約８５ｄＢ以上の音量で再生できるような音量に設定されている。
【００４５】
以上説明したように、本実施形態の人体検知機能付スピーカ装置では、人体を検知していない場合でも、リモコン設定器５０を用いて報知音などの設定状態や、音声メモリ１４に記憶された報知音を音声で出力させることができるから、確認作業を容易に行えるという利点がある。また、スピーカ本体１０は一般に天井面や壁面などの高所に設置されているが、リモコン設定器５０を用いて離れた場所から確認作業が行えるので、スピーカ本体１０を設置場所から取り外して確認作業を行う必要がなく、確認作業を容易に行えるという利点もある。
【００４６】
尚、本実施形態ではリモコン設定器５０を用いて報知音などの設定状態を確認しているが、スピーカ本体１０に設定状態を確認するためのスイッチを設け、このスイッチの操作に応じて報知音などの設定状態や、音声メモリ１４に記憶された報知音を音声で出力させるようにしても良い。
【００４７】
【発明の効果】
上述のように、請求項１の発明は、検知エリア内で人体を検知するとともに、その人体の移動方向を検知する検知手段、人体の各移動方向に対応した報知音を記憶する記憶手段、前記記憶手段に記憶された報知音を再生する再生手段、外部よりワイヤレス信号で送信される設定確認信号を受信する受信手段、及び前記検知手段が人体を検知するとその移動方向に応じた報知音を再生手段により再生させるとともに、前記受信手段が設定確認信号を受信すると記憶手段に記憶された各移動方向の報知音を再生手段により音声で出力させる制御手段を有するスピーカ本体と、記憶手段に記憶された各移動方向の報知音を再生手段から音声で出力させるための操作を行う第１の操作手段、第１の操作手段の操作に応じて外部へワイヤレス信号にて設定確認信号を送信する送信手段を有するリモコン設定器とを備え、上記記憶手段には、報知音をそれぞれ記憶する記憶ブロックが複数設けられ、各記憶ブロックに報知音を録音させる録音手段と、各記憶ブロックに記憶された報知音の中から各移動方向に対応して再生する報知音を設定する設定手段とをスピーカ本体に設けるとともに、上記リモコン設定器に、上記記憶手段の個別の記憶ブロックを指定して、当該記憶ブロックに記憶された報知音を強制的に再生させるための操作を行う第２の操作手段を設け、送信手段は、第２の操作手段の操作に応じて外部へワイヤレス信号にて報知音再生信号を送信させており、上記制御手段は、受信手段の受信した報知音再生信号に基づいて指定された記憶ブロックの報知音を再生手段により再生させることを特徴とし、リモコン設定器の第１の操作手段を操作すると、送信手段がワイヤレス信号にて設定確認信号を送信し、この設定確認信号を受信したスピーカ本体では、制御手段が、設定確認信号に応じて各移動方向の報知音を再生手段により音声で出力させているので、人体を検知していない状態でも報知音を強制的に再生でき、リモコン設定器を用いて離れた場所から報知音を音声で容易に確認できるという効果がある。
【００４８】
また更に、録音手段を用いて記憶手段の各記憶ブロックに所望の報知音を録音させることができ、且つ設定手段を用いて各記憶ブロックに録音させた報知音の中から所望の報知音を各移動方向に対応して設定できるから、使用状況に応じた報知音を再生できるという効果がある。

[0023]
FIG. 12 is a circuit block diagram of the power supply unit including the main power supply unit 18 and the auxiliary power supply unit 19. The main power supply unit 18 converts the power supply voltage of the AC power supply AC input via the power switch SW and the fuse F. After being stepped down by Tr and full-wave rectified by a full-wave rectifier DB, it is stabilized by a 5V power supply circuit 18a using a power supply IC such as a three-terminal regulator. The main power supply unit 18 is arranged on the front side of the mounting base 23 and is electrically connected to the circuit board 26 via the cable 27, and the main power supply unit 18 is in a state where the case 20 is held by the mounting base 23. To the circuit board 26 via the cable 27. Connectors 27a are connected to both ends of the cable 27, and are connected to receiving-side connectors 28 and 28 provided on the main power supply unit 18 and the circuit board 26, respectively. The power switch SW of the main power supply unit 18 is formed of a push button switch. When the case 20 is attached to the mounting base 23, the push button of the power switch SW is pressed against the mounting base 23 side by the case 20 and becomes conductive. The power supply unit 18 is energized.
[0024]
The auxiliary power supply unit 19 includes a 5V power supply unit 19a that generates a constant voltage of about 5V using the battery B (battery) as a power supply.

[0025]
Next, the operation of the speaker device with a human body detection function will be described. FIG. 2 shows detection areas of the two human sensors 12a and 12b held by the human sensor unit 25. The detection areas A1 and A2 of the human sensors 12a and 12b are the movements of the human bodies M1 and M2. They are arranged side by side in the direction (vertical direction in FIG. 2). When the human body M1 moves from the lower side to the upper side in FIG. 2 (this direction is referred to as direction D1), the human body M1 passes through the detection area A1 of the human sensor 12a and the detection area A2 of the human sensor 12b. The human body M1 is detected in the order of the human sensor 12a → the human sensor 12b. On the other hand, when the human body M2 moves from the upper side to the lower side in FIG. 2 (this direction is referred to as the direction D2), the human body M2 is detected in the order of the human sensor 12b → the human sensor 12a. To do. As described above, since the timing of sensing the human body is different between the two human sensors 12a and 12b in accordance with the moving directions D1 and D2 of the human body, the control unit 11 of the speaker body 10 uses both human sensors 12a and 12b. The moving direction of the human body can be determined based on the human body detection signal, and the notification sound associated with each of the moving directions D1 and D2 is reproduced by the recording / reproducing circuit 13 and output from the speaker SP.
[0026]
By the way, a plurality of areas (hereinafter referred to as boxes) for storing the notification sound are prepared in the audio memory 14, and consecutive box numbers from 0 to 12 are assigned to each box. Table 1 shows the alarm sounds stored in each box. No sound is recorded in the 0th box (silence), and the 1st to 4th boxes are "Welcome". Four kinds of notification sounds such as "Thank you", "Ping Pong" and "Pororon" are recorded in advance. At the time of shipment, the notification sound is not recorded in the boxes No. 5 to No. 12, and the user can record the desired notification sound.
[0027]
[Table 1]

[0028]
Here, a method for recording a desired notification sound will be described. In general, since the speaker body 10 is installed and used at a high place such as a ceiling or a wall surface, when recording a notification sound, the case 20 is removed from the mounting base 23 and moved to a place where the recording work can be easily performed. I do. When the case 20 is detached from the mounting base 23 and used, the cable 27 for connecting the main power supply unit 18 and the circuit board 26 is removed, and the battery B is placed in the battery box 29 provided on the rear side of the case 20. Attach and operate battery B as power source.
[0029]
When recording the notification sound, first, the operation knob 31 of the mode switch S1 is slid to the lower switching position to switch the operation mode to the recording mode. As described above, the light emitting diode LD2 changes its emission color according to the operation mode, and lights up in red in the normal mode, orange in the reproduction mode, and green in the recording mode.
[0030]
Here, as a method of inputting an audio signal to the recording / reproducing circuit 13, a method of inputting an audio signal by converting the audio into an internal microphone MC1, and an audio signal from an external microphone are input via the microphone input unit MC2. There are three methods: a method and a method of inputting an audio signal from an AV device via the line input unit AVX. If no plug is connected to the microphone input unit MC2 or the line input unit AVX, an audio signal from the built-in microphone MC1 is input to the recording / playback circuit 13. On the other hand, when the plug is connected to the microphone input unit MC2 or the line input unit AVX, the input from the microphone MC1 is automatically disconnected, and the audio signal from the external microphone or AV device is transmitted to the microphone input unit MC2 or the line input unit. The audio signal is automatically input to the recording / reproducing circuit 13 through AVX, and the input audio signal is output from the speaker SP.
[0031]
When the operation mode is switched to the recording mode, a level meter (not shown) built in the recording / playback circuit 13 starts to operate, detects the signal level of the input signal, and displays the signal level with the display color of the light emitting diode LD3. Is displayed. The light emitting diode LD3 is lit in yellow when the volume of the input signal is low, green when it is optimal, and red when it is high, so that the volume of the input signal can be visually confirmed. Thus, the user inputs a sound (voice message, melody sound, etc.) to be recorded by any one of the three methods described above, and adjusts the volume of the input signal while watching the light emission color of the light emitting diode LD3. After setting the recording level to the optimum value, when the box number to be recorded is input by the operation keys K5 to K12 of the remote controller setting device 50, the control unit 51 causes the transmission unit 53 to transmit a signal indicating the box number. At this time, the receiving unit 15 of the speaker body 10 receives the signal transmitted from the remote control setting device 50, and the control unit 11 causes the light emitting diode LD2 to blink green for 5 seconds at a cycle of 1 second based on the received signal. The light emitting diode LD2 is lit in green and the recording operation of the recording / reproducing circuit 13 is started. Thereafter, when the user presses the operation key K0 of the remote controller setting device 50, the control unit 51 transmits a signal for ending the recording operation from the transmission unit 53, and the reception unit 15 receives this signal in the speaker body 10, The control unit 11 ends the recording operation of the recording / reproducing circuit 13 and records the audio signal in the designated box of the audio memory 14.
[0032]
Here, when the operation keys K5 to K12 corresponding to other box numbers are pressed while the light emitting diode LD2 is blinking, the operation keys K5 to K12 pressed later are given priority, and the remote controller is operated according to the key operation. After the control unit 11 blinks the light emitting diode LD2 for 5 seconds from the time when the signal transmitted from the transmitter 50 is received, the input audio signal is recorded in the box designated by the operation key pressed later. . If any of the operation keys K5 to K12 is pressed after the light emitting diode LD2 is switched to the lighting state, the key input is ignored. Note that the time of the audio signal that can be recorded in each box (recordable time) is determined in advance, and recording is performed in this box after the recording operation is started until the operation key K0 of the remote control setting device 50 is pressed. When a possible time elapses, the control unit 11 ends the recording operation of the recording / reproducing circuit 13 and outputs a warning sound from the speaker SP.
[0033]
By the way, when the operation keys K0 to K4 are pressed when the recording box is designated, the boxes No. 0 and No. 1 to No. 4 are for fixed sounds and cannot be recorded by the user side. A warning sound is output from the speaker SP using the recording / reproducing circuit 13. Further, when a key other than the operation keys K0 to K12 representing numbers is pressed in the state of switching to the recording mode, the input is ignored and a warning sound is output from the speaker SP using the recording / playback circuit 13. . In addition, the remote controller setting unit 50 does not have a key for erasing the recorded contents of the blocks (memory blocks) from No. 5 to No. 12 that can be recorded by the user, and wants to erase the previously recorded audio signal. Can be deleted by overwriting the block.
[0034]
As described above, the speaker device with a human body detection function of the present embodiment has a function of recording a desired notification sound, and uses this recording function for voice and music adapted to the atmosphere of the store, for guidance in the building Can be output from the speaker 6 and can be used for various purposes, and the installation location can be set not only at the entrance / exit of the building but also within the building or installed outdoors. Is possible. Voice messages (greetings and warnings in Japanese and foreign languages), sound effects (natural sounds such as birdsongs and waves, bells, bells, etc.) If a compact disc with melody sound, alarm sound and ringing tone is prepared and this compact disc is attached at the time of shipment, the sound recorded on this compact disc can be played back on a compact disc player, through the line input section AVX. By inputting to the recording / reproducing circuit 13, a desired sound can be recorded as a notification sound from among the sounds recorded on the compact disc, and versatility is enhanced.
[0035]
Further, since the speaker main body 10 is used by being installed on a construction surface such as a ceiling or a wall surface, it is difficult to perform setting operations frequently performed on the main body side. The operation is performed.
[0036]
Here, a method of selecting a combination of notification sounds to be reproduced at the time of detecting a human body from notification sounds registered in twelve boxes of the voice memory 14 using the remote controller setting device 50 will be described. In the present embodiment, the notification sound when the human body moves in the direction D1 and the notification sound when the human body moves in the direction D2 can be selected as one set (pattern) so that a plurality of patterns (for example, two patterns in this embodiment) can be selected. The two patterns are called a pattern P1 and a pattern P2, respectively.
[0037]
For example, when the notification sound recorded in the number 7 box is selected as the notification sound in the direction D1 of the pattern P1, when the operation key K31 of the remote control setting device 50 is pressed while the case 20 is attached to the attachment base 23, transmission is performed. A signal for switching the operation mode to the normal mode is transmitted from the unit 53. Upon receiving this signal, the control unit 11 of the speaker body 10 switches the operation mode to the normal mode, and the light emitting diode LD2 is lit in red. Thereafter, when the operation key K21 of the remote controller setting device 50 is pressed, a signal for designating the direction D1 of the pattern P1 is transmitted from the transmission unit 53, and the control unit 11 of the speaker body 10 receives this signal and an internal timer (not shown). ) To start counting. Then, when the operation key (K7) corresponding to the box number (7) to be selected is pressed before the counting operation by the internal timer (for example, 5 seconds) is completed, the transmitter 53 starts the 7th operation. In response to this signal, the control unit 11 of the speaker body 10 resets and restarts the count operation of the internal timer. Thereafter, when the operation key K37 of the remote control setting device 50 is pressed before the counting operation of the counting time (for example, 5 seconds) by the internal timer is completed, a signal for registering the notification sound is transmitted from the transmission unit 53, Upon receiving this signal, the control unit 11 of the speaker main body 10 serving as setting means causes the notification sound recorded in the designated box to be output from the speaker SP and sets the notification sound as the notification sound in the direction D1 of the pattern P1. Here, if there is no signal transmission from the remote control setting device 50 until the internal timer of the control unit 11 finishes the counting operation, the notification sound selection processing is ended. In addition, when the notification sound is not recorded in the designated box or when the 0th box is designated, the notification sound becomes silent, and the notification sound is output even if a person moving in that direction is detected. Disappear. Other notification sounds can be selected in the same procedure as described above. Tables 2 and 3 show notification sound setting examples. In the example shown in Table 2, when the human body is moving in the direction D1 when the pattern P1 is selected, the notification sound a is displayed, and the human body is displayed in the direction D2. When the pattern P2 is selected, the notification sound b is output. When the pattern P2 is selected, the notification sound c is output when the human body is moving in the direction D1, and the notification sound d is output when the human body is moving in the direction D2. Is output.
[0038]
[Table 2]

[0039]
[Table 3]

[0040]
As described above, desired notification sounds are recorded in a plurality of boxes provided in the voice memory 14, and the notification sounds recorded in each box can be selected as notification sounds in the directions D1 and D2 of the patterns P1 and P2. However, the output pattern can be alternately switched between the pattern P1 and the pattern P2 by using the operation key K33 of the remote controller setting device 50. When the operation key K33 of the remote controller setting device 50 is pressed, the control unit 51 causes the transmission unit 53 to transmit a signal for inverting the output pattern. When the receiving unit 15 of the speaker body 10 receives this signal, the control unit 11 alternately switches the output pattern of the notification sound to be reproduced based on the signal received by the receiving unit 15 to the pattern P1 or P2, and the direction D1 The notification sound in the direction D2 can be switched in one set. Instead of using the operation key K33 of the remote controller setting device 50, the pattern can be switched by using the pattern changeover switch S2 of the speaker body 10, and each time the operation button 32 of the pattern changeover switch S2 is pressed, the pattern P1 or P2 is changed. It can be switched alternately.
[0041]
Furthermore, the setting state of the speaker body 10 can be confirmed using the operation key K36 of the remote control setting device 50. When confirming the setting, first, the operation key K31 of the remote controller setting device 50 is pressed to transmit a signal for switching from the remote control setting device 50 to the reproduction mode. In the speaker main body 10, upon receiving this signal, the control unit 11 switches the operation mode to the reproduction mode, and causes the light emitting diode LD2 to emit light in orange. When the operation key K36 (first operation means) of the remote controller setting device 50 is pressed in this state, the control unit 51 causes the transmission unit 53 to transmit a setting confirmation signal for confirming the setting state. When the receiving unit 15 of the speaker main body 10 receives this setting confirmation signal, the control unit 11 controls the recording / playback circuit 13 to follow the voice message “Check the current operating environment” in the direction D1. The sound message for the time and the direction sound for the direction D2 are output from the speaker SP. Furthermore, when the continuous sound function is on, the sound is “continuous sound is on”, and when it is off, the sound message is “continuous sound is off”. Is output from the speaker SP. If silence is set as the notification sound in the direction D1 or D2, the recording / playback circuit 13 outputs a message “no sound” from the speaker SP. Then, when the operation key K31 of the remote control setting device 50 is pressed after confirming the setting state, a signal for switching to the normal mode is transmitted from the remote control setting device 50, and the control unit 11 of the speaker body 10 receives the signal to change the operation mode. Switch to normal mode. As described above, since the current notification sound setting can be confirmed using the remote controller setting device 50, the confirmation work can be easily performed even when the speaker body 10 is installed at a high place such as a ceiling or a wall surface. Can do.
[0042]
It is also possible to confirm by actually sounding the notification sound recorded in each block using the remote controller setting device 50. When the case 20 is held on the mounting base 23, the operation mode is switched to the normal mode by the mode changeover switch S1, and then the operation key K31 of the remote control setting device 50 is pressed to switch from the remote control setting device 50 to the reproduction mode. Upon receiving this signal, the control unit 11 of the speaker body 10 switches the operation mode to the reproduction mode and causes the light emitting diode LD2 to emit light in orange. Further, when the case 20 is detached from the mounting base 23 and driven by the battery, the operation mode of the speaker body 10 is automatically switched to the reproduction mode. When one of the operation keys K1 to K12 (second operation means) of the remote controller setting device 50 is pressed in the state in which the operation mode of the speaker body 10 is switched to the reproduction mode in this way, the notification sound of the corresponding block number is displayed. Is transmitted from the transmission unit 53. When the receiving unit 15 of the speaker main body 10 receives the notification sound reproduction signal, the control unit 11 reproduces the notification sound of the registration number designated by using the recording / playback circuit 13 and outputs it from the speaker SP, and each block The contents of the audio signal recorded in the can be confirmed using the remote controller setting device 50. Then, when the operation key K31 of the remote control setting device 50 is pressed after confirming the setting state, a signal for switching to the normal mode is transmitted from the remote control setting device 50, and the control unit 11 of the speaker body 10 receives the signal to change the operation mode. Switch to normal mode. A sticker 61 as shown in FIG. 13 is pasted on the back of the remote control setting device 50, and the type of sound recorded in the boxes 1 to 12 is displayed so that it can be visually confirmed. Also good.
[0043]
Further, the continuous ringing function can be turned on / off by the operation key K32 of the remote controller setting device 50. When the operation key K32 is pressed, a signal for turning on or off the continuous ringing function is transmitted from the remote controller setting device 50, and the control unit 11 of the speaker body 10 turns on or off the continuous ringing function in response to this signal. Here, when the continuous sound function is turned off, when a human body is detected once and a notification sound is output, the notification sound is not output within a certain time (for example, within about 20 seconds), so that a plurality of humans are continuously connected. Thus, it is possible to prevent the notification sound from continuously sounding when the person goes in and out or when a person stops.
[0044]
Further, the volume of the speaker SP can be changed by using the operation keys K34 and K35 of the remote controller setting device 50 or the switches S3 and S4 of the speaker body 10. The volume of the speaker SP can be switched between seven levels including the silent state. When the operation key K34 or the switch S3 is pressed once while the operation mode is set to the normal mode, the recording / playback circuit 13 outputs the notification sound in both directions of the currently selected pattern at a louder level by one speaker SP. When the operation key K35 or the switch S4 is pressed once, the recording / playback circuit 13 causes the speaker SP to output a notification sound in both directions of the currently selected pattern with a small volume. On the other hand, when the operation mode is set to the playback mode, when the operation key K34 or the switch S3 is pressed once, the recording / playback circuit 13 causes the loudspeaker SP to output the last output notification sound from the speaker SP with one level louder. When the operation key K35 or the switch S4 is pressed once, the recording / playback circuit 13 causes the speaker SP to output the last output notification sound from the speaker SP with a small volume. Note that the maximum value of the volume of the speaker SP is set so that the notification sound recorded by the user can be reproduced with a volume of about 85 dB or more.
[0045]
As described above, in the speaker device with a human body detection function according to the present embodiment, even when a human body is not detected, a setting state such as a notification sound using the remote control setting device 50 or a notification stored in the voice memory 14 is used. Since the sound can be output by voice, there is an advantage that the confirmation work can be easily performed. The speaker body 10 is generally installed at a high place such as a ceiling surface or a wall surface. However, since the confirmation work can be performed from a remote place using the remote controller setting device 50, the confirmation work is performed by removing the speaker body 10 from the installation place. There is also an advantage that the confirmation work can be easily performed.
[0046]
In the present embodiment, the setting state of the notification sound or the like is confirmed using the remote controller setting device 50, but a switch for confirming the setting state is provided in the speaker body 10, and the notification sound is determined according to the operation of this switch. The notification state stored in the voice memory 14 may be output by voice.
[0047]
