Description

本発明は、画像再生装置を遠隔操作するリモコン及びそのリモコンを有する視聴システムに関する。   The present invention relates to a remote controller for remotely operating an image playback device and a viewing system having the remote controller.

深夜の視聴等で周囲に迷惑をかけたくない場合など、テレビ受像機などの画像再生装置の音を消して、画像再生装置に接続されたヘッドフォンを装着してテレビ放送や再生映像等を視聴する場合がある。このとき、画像再生装置からヘッドフォンまでのコードの引き回しにより、物や人が移動する際に引っ掛かってしまったり、コードの長さによって視聴者の移動範囲が自ずと限定されてしまったりする。   If you don't want to disturb your surroundings at night, for example, you can turn off the sound of an image playback device such as a television receiver and wear headphones connected to the image playback device to watch TV broadcasts and playback videos. There is a case. At this time, the cord is routed from the image playback device to the headphone, so that an object or person is caught when moving, or the moving range of the viewer is naturally limited by the length of the cord.

このため、視聴者の身近におかれるリモコンにヘッドフォン端子をつけたものがある(例えば、特許文献1参照)。
図1は、ヘッドフォン端子付きのリモコンを示す図である。テレビ受像機1の送信部5より搬送波に乗せた音声信号を送信し、リモコン2の受信部6で受信した後、リモコン2のヘッドフォン端子7に接続されたヘッドフォン3で音声を聞くことができる。

The remote controller 21 receives an audio signal from the television receiver 22 and recognizes the sound by the vibration of the bone conduction speaker 31 incorporated in the remote controller 21 directly transmitting the sound to the cochlea of the inner ear through the human skull. it can.

図3は、本実施の形態のリモコンを有する視聴システム100について示したブロック図である。本実施例のリモコンを有する視聴システム100は、テレビ受像機22と、リモコン21とで構成される。   FIG. 3 is a block diagram showing a viewing system 100 having a remote control according to the present embodiment. A viewing system 100 having a remote control according to the present embodiment includes a television receiver 22 and a remote control 21.

まず、テレビ受像機22について説明する。
テレビ受像機22は、リモコン21からの赤外線等による制御信号を受信する受信デバイス64(赤外線受光器等)と、この制御信号によってチャンネルの切り替えや音量の制御などを行う制御部68と、放送波80を受信する受信アンテナ63と、ビデオ入力等種々の電化製品と接続する外部入力65と、搬送波に乗せて変調された放送波80を復調する復調部55と、を有しており、画像信号70および音声信号66を画像処理部56と音声処理部54に分けて処理を行っている。
First, the television receiver 22 will be described.
The television receiver 22 includes a receiving device 64 (infrared light receiver or the like) that receives a control signal by infrared rays or the like from the remote controller 21, a control unit 68 that performs channel switching or volume control using the control signal, and a broadcast wave. 80, a receiving antenna 63 for receiving 80, an external input 65 connected to various electric appliances such as a video input, and a demodulator 55 for demodulating a broadcast wave 80 modulated on a carrier wave. 70 and the audio signal 66 are divided into the image processing unit 56 and the audio processing unit 54 for processing.

画像処理部56は、復調部55から取り出した画像信号70または外部入力65からの画像信号71のうちユーザーが選択しているものを出力し、この画像出力信号72に基づいて表示デバイス57(例えば、CRT,液晶ディスプレイ,PDP等)によって画像が表示される。   The image processing unit 56 outputs the image signal 70 taken out from the demodulation unit 55 or the image signal 71 selected by the user from the external input 65, and the display device 57 (for example, based on the image output signal 72) , CRT, liquid crystal display, PDP, etc.).

音声処理部54は、復調部55から取り出した音声信号66または外部入力65からの音声信号67のうちユーザーが選択しているものを出力し、この音声出力信号73をプリアンプ58およびパワーアンプ59で増幅した後、テレビ受像機22に備えられたスピーカ60によって音声が再生される。また、プリアンプ58で音声出力信号73を増幅した後、ヘッドフォンアンプ61で増幅しヘッドフォン端子62へ出力再生することも可能である。   The audio processing unit 54 outputs the audio signal 66 taken out from the demodulation unit 55 or the audio signal 67 selected by the user from the external input 65, and this audio output signal 73 is output by the preamplifier 58 and the power amplifier 59. After amplification, the sound is reproduced by the speaker 60 provided in the television receiver 22. It is also possible to amplify the audio output signal 73 by the preamplifier 58, amplify it by the headphone amplifier 61, and output and reproduce it to the headphone terminal 62.

音声出力信号73は、骨伝導スピーカ31の再生能力に応じた所定の周波数帯域だけを取り出す帯域フィルタ53でフィルタリングされ、フィルタリングされた音声信号74を変調部52で搬送波に乗せ、送信デバイス51(アンテナあるいは赤外線発光器等)から電波あるいは赤外線等の電磁波81として外部へ送信される。例えば、帯域フィルタ53は300Hz〜3kHz程度の帯域で骨伝導スピーカ31用の音声信号を伝達するものが好ましい。なお、この300Hz〜3kHz程度の帯域であればセリフなどの人の声を明瞭に聴くことが可能である。   The audio output signal 73 is filtered by a band filter 53 that extracts only a predetermined frequency band corresponding to the reproduction capability of the bone conduction speaker 31, and the filtered audio signal 74 is put on a carrier wave by the modulation unit 52, and the transmission device 51 (antenna Alternatively, it is transmitted to the outside as an electromagnetic wave 81 such as radio waves or infrared rays from an infrared light emitter or the like. For example, the band filter 53 is preferably one that transmits an audio signal for the bone conduction speaker 31 in a band of about 300 Hz to 3 kHz. Note that it is possible to clearly hear the voice of a person such as a speech in the band of about 300 Hz to 3 kHz.

次に、リモコン21について説明する。
リモコン21は、テレビ受像機22からの電波あるいは赤外線等の電磁波81を受信する受信デバイス35(アンテナあるいは赤外線受光器等)と、搬送波に乗せて変調された電磁波81をもとの信号に戻す復調部34と、復調部34から取り出した復調信号75を骨伝導スピーカ31の特性に合わせた周波数に補正するイコライザー33と、骨伝導スピーカ31の音量調整を行うことができる出力制御部32と、音声信号76を機械的な振動に変換する骨伝導スピーカ31と、操作部36と、制御部37と、制御部37からの制御信号78を送信する送信デバイス41(赤外線発光器等)と、リモコン21が人体に接触しているかを検知する人検知部90とを有している。
Next, the remote controller 21 will be described.
The remote controller 21 receives a reception device 35 (antenna or infrared receiver) that receives electromagnetic waves 81 such as radio waves or infrared rays from the television receiver 22, and demodulation that returns the electromagnetic waves 81 that are modulated on a carrier wave to the original signals. 34, an equalizer 33 that corrects the demodulated signal 75 extracted from the demodulator 34 to a frequency that matches the characteristics of the bone conduction speaker 31, an output control unit 32 that can adjust the volume of the bone conduction speaker 31, and an audio A bone conduction speaker 31 that converts the signal 76 into mechanical vibration, an operation unit 36, a control unit 37, a transmission device 41 (such as an infrared light emitter) that transmits a control signal 78 from the control unit 37, and the remote controller 21. And a human detection unit 90 that detects whether or not the human body is in contact with the human body.

イコライザー33は、ノーマルモードとセリフモードを有し、ユーザーはどちらかのモードを選択することがでる。セリフモードではノーマルモードに対して言葉の発音に重要な1.5kHz〜3kHz帯域を3dB程度増幅させることができる。このため、セリフモードは、会話が多い番組等の視聴に適している。   The equalizer 33 has a normal mode and a speech mode, and the user can select either mode. In the serif mode, the 1.5 kHz to 3 kHz band, which is important for the pronunciation of words, can be amplified by about 3 dB compared to the normal mode. For this reason, the speech mode is suitable for viewing a program or the like with much conversation.

また、リモコン21の内部に出力制御部32を設けたことで、骨伝導スピーカ31の音量調整を行うことができる。
これにより、スピーカ60からの音声と骨伝導スピーカ31の音声を同時に聞く場合において、スピーカ60の音量と骨伝導スピーカ31からの音量とのバランスの調整ができるので、室内環境や視聴者の好みに柔軟に対応させることができる。
Further, by providing the output control unit 32 inside the remote controller 21, the volume of the bone conduction speaker 31 can be adjusted.
Thereby, when listening to the sound from the speaker 60 and the sound from the bone conduction speaker 31 at the same time, the balance between the volume of the speaker 60 and the volume from the bone conduction speaker 31 can be adjusted. It can be flexibly handled.

人検知部90は、(+)電極43と、(−)電極44と、人検知部42とを有し、両電極間の抵抗値を人検知部42で監視している。抵抗値が所定値以上と測定されると制御部37によってリモコン21は机上等に置かれた状態(人が持っていない状態)と判断し、制御部37は受信デバイス35、イコライザー33、出力制御部32、骨伝導スピーカ31へ動作停止命令を送信する。   The human detection unit 90 includes a (+) electrode 43, a (−) electrode 44, and a human detection unit 42, and the resistance value between both electrodes is monitored by the human detection unit 42. When the resistance value is measured to be a predetermined value or more, the control unit 37 determines that the remote controller 21 is placed on a desk or the like (a state that a person does not have), and the control unit 37 controls the receiving device 35, the equalizer 33, and the output control. The operation stop command is transmitted to the unit 32 and the bone conduction speaker 31.

これにより机上等での不快な振動を防止するとともにリモコン21の無駄な電力消費を防ぐことができる。なお、人間の抵抗値が1MΩ程度であることを考慮すれば、制御部37が両電極間の抵抗は余裕を持たせて約3MΩ以上と測定した場合に動作停止命令を送信するように設定するのが好ましい。   As a result, unpleasant vibration on the desk or the like can be prevented, and wasteful power consumption of the remote controller 21 can be prevented. In consideration of the human resistance value of about 1 MΩ, the control unit 37 is set to transmit an operation stop command when the resistance between both electrodes is measured to be about 3 MΩ or more with a margin. Is preferred.

また、ユーザーがリモコン21が人体から僅かに離れただけでその動作を停止すると、視聴者が動く度に動作が停止して使いづらいため、所定の時間以上離れた場合にのみ動作を停止させることが好ましい。   In addition, if the user stops the operation of the remote controller 21 only slightly away from the human body, the operation stops every time the viewer moves and is difficult to use. Therefore, the operation is stopped only when the user is away from the predetermined time. Is preferred.

このため、制御部37は、マイコン38の他、タイマー39を有している。タイマー39は両電極間の抵抗値が所定値以上と測定されると時間測定を開始する。そして、この測定時間が予め設定された所定時間以上になったとき、骨伝導スピーカ31の動作を停止するよう設定する。   Therefore, the control unit 37 has a timer 39 in addition to the microcomputer 38. The timer 39 starts time measurement when the resistance value between both electrodes is measured to be equal to or greater than a predetermined value. And when this measurement time becomes more than predetermined time set beforehand, it sets so that operation of bone conduction speaker 31 may be stopped.

さらに、タイマー39による測定時間が所定時間を越えたとき、制御部37がテレビ受像機22に電源オフ信号を送信することにより、テレビ受像機22の電源をオフにすることもできる。なお、テレビ受像機22の電源オフのための所定時間は、前記の骨伝導スピーカ31の動作を停止させる所定時間とは異なるものでもよい。   Furthermore, when the measurement time by the timer 39 exceeds a predetermined time, the control unit 37 can also turn off the power of the television receiver 22 by transmitting a power off signal to the television receiver 22. Note that the predetermined time for turning off the power of the television receiver 22 may be different from the predetermined time for stopping the operation of the bone conduction speaker 31.

図4は、本実施の形態のリモコンを有する視聴システムにおいて、人検知部90とタイマー39とを組み合わせて作動させた場合の動作フローを示すフローチャートである。
以下、本実施の形態のリモコンを有する視聴システムの動作フローを説明する。
FIG. 4 is a flowchart showing an operation flow when the human detection unit 90 and the timer 39 are operated in combination in the viewing system having the remote control according to the present embodiment.
Hereinafter, an operation flow of the viewing system having the remote control according to the present embodiment will be described.

まず、テレビ受像機22の電源をON(ステップS1)した後、リモコン21の電源をONする(ステップS2)。   First, after turning on the power of the television receiver 22 (step S1), the power of the remote controller 21 is turned on (step S2).

人検知部42が(+)電極43と、(−)電極44との間の抵抗値を監視する(ステップS3)。マイコン38によって両電極間の抵抗値が3MΩ以上と測定された場合(ステップS4)にタイマー39が時間測定を開始する(ステップS5)。   The human detection unit 42 monitors the resistance value between the (+) electrode 43 and the (−) electrode 44 (step S3). When the resistance value between both electrodes is measured by the microcomputer 38 to be 3 MΩ or more (step S4), the timer 39 starts time measurement (step S5).

一方、マイコン38によって両電極間の抵抗値が3MΩ以上と測定されなかった場合(ステップS4)は、引き続き両電極間の抵抗値を監視する(ステップS3)。   On the other hand, if the resistance value between the two electrodes is not measured by the microcomputer 38 to be 3 MΩ or more (step S4), the resistance value between the two electrodes is continuously monitored (step S3).

タイマー39が時間測定を開始後、予め設定された所定時間を経過すると、制御部37は骨伝導スピーカ31へ動作停止命令を送信し、骨伝導スピーカ31を停止させる(ステップS7)。   When a predetermined time elapses after the timer 39 starts measuring time, the control unit 37 transmits an operation stop command to the bone conduction speaker 31 and stops the bone conduction speaker 31 (step S7).

なお、マイコン38は、時間測定中でも両電極間の抵抗値を監視しているため時間測定開始後、所定時間経過していない場合(ステップS6)は、ステップS3→ステップS4→ステップS5→ステップS6→ステップS3→ステップS4・・・のようにループ制御を行っている。   Since the microcomputer 38 monitors the resistance value between both electrodes even during time measurement, if the predetermined time has not elapsed after the start of time measurement (step S6), step S3 → step S4 → step S5 → step S6. → Step S3 → Step S4...

また、骨伝導スピーカ31の停止とともに、テレビ受像機22の電源をOFFにするように制御することもできる。すなわち、制御部37は送信デバイス41からから動作停止命令の信号を送信し(ステップS9)、この動作停止命令の信号をテレビ受像機22の受信デバイス64が受信して、テレビ受像機の制御部68に送り、制御部68の制御によりテレビ受像機22の電源がOFFになる(ステップS10)。   Further, it is possible to control the television receiver 22 to be turned off as the bone conduction speaker 31 is stopped. That is, the control unit 37 transmits an operation stop command signal from the transmission device 41 (step S9), and the reception device 64 of the television receiver 22 receives the operation stop command signal, so that the control unit of the television receiver is received. The power of the television receiver 22 is turned off under the control of the control unit 68 (step S10).

次に、本実施の形態のリモコンの構造について、具体的な実施例を挙げて説明する。
(実施例1)
図5は、実施例1に係るリモコンの外観斜視図である。(a)は上面斜視図であり、(b)は底面斜視図である。
Next, the structure of the remote controller according to the present embodiment will be described with reference to specific examples.
Example 1
FIG. 5 is an external perspective view of the remote controller according to the first embodiment. (A) is a top perspective view, (b) is a bottom perspective view.

リモコン21は、略立方形状を有し、長手方向と直角方向の一側面中央にはリモコン21とテレビ受像機22との間で電波や赤外線等の電磁波を送受信する略楕円形状の送信デバイス41と受信デバイス35が設けられている。本実施形態においては1つの略楕円形状デバイスが送信デバイス41、受信デバイス35の2つの役割を兼ねている。   The remote control 21 has a substantially cubic shape, and a substantially elliptical transmission device 41 that transmits and receives electromagnetic waves such as radio waves and infrared rays between the remote control 21 and the television receiver 22 at the center of one side surface in a direction perpendicular to the longitudinal direction. A receiving device 35 is provided. In the present embodiment, one substantially elliptical device serves as both the transmitting device 41 and the receiving device 35.

リモコン21の上面側には複数の突起したボタンが設けられている。これらは、テレビ受像機22を遠隔制御するためのボタンであり、電源ボタン25、音量調節ボタン26、チャンネル切り替えボタン27、ファンクションボタン28等から構成され全体で操作部36をなしている。   A plurality of protruding buttons are provided on the upper surface side of the remote controller 21. These are buttons for remotely controlling the television receiver 22, and are composed of a power button 25, a volume control button 26, a channel switching button 27, a function button 28, and the like, and constitute an operation unit 36 as a whole.

リモコン21の底面側には中央よりやや送信デバイス41および受信デバイス35側に、ドーナツ形の金属板からなる(−)電極44と、ドーナツ形の金属板の中にドーナツ形より直径が小さい円形の金属板からなる(+)電極43が設けられている。これら(−)電極44と(+)電極43は互いに接触することなく配置されている。   The remote control 21 has a (−) electrode 44 made of a doughnut-shaped metal plate on the bottom side of the remote control 21 slightly on the transmission device 41 and the reception device 35 side, and a circular shape having a smaller diameter than the donut shape in the donut-shaped metal plate. A (+) electrode 43 made of a metal plate is provided. The (−) electrode 44 and the (+) electrode 43 are arranged without contacting each other.

また、上面側の送信デバイス41および受信デバイス35の反対側の端には、リモコン21の作動に必要な電池の挿入口を覆うように長方形状の蓋23が装着されている。   In addition, a rectangular lid 23 is attached to the opposite ends of the transmission device 41 and the reception device 35 on the upper surface side so as to cover a battery insertion slot necessary for the operation of the remote controller 21.

さらに、リモコン21の筐体の外側、例えば底面側の4隅にはゴム材やスポンジ材等の弾性部材からなる円形の振動吸収部材24が設けられている。リモコン21に内蔵された骨伝導スピーカ31の作動中にリモコン21を机上等に置いても、これら振動吸収部材24が骨伝導スピーカ31の振動を吸収するので不快な音をたてることがない。   Furthermore, circular vibration absorbing members 24 made of an elastic member such as a rubber material or a sponge material are provided on the outside of the casing of the remote controller 21, for example, at the four corners on the bottom side. Even if the remote controller 21 is placed on a desk or the like while the bone conduction speaker 31 incorporated in the remote controller 21 is in operation, the vibration absorbing member 24 absorbs the vibration of the bone conduction speaker 31 and thus does not make an unpleasant sound.

なお、リモコン21は、図2に示すように頬に密着するようにあてると骨伝導スピーカ31の振動が頭骨に伝わりやすく効果的な使用ができる。そして、音声を聴いている間は、底面側にある電極44および電極43を頬に密着させておけば骨伝導スピーカ31が突然停止することはないため、ストレスなくテレビ放送の音声を聞くことができる。   Note that the remote control 21 can be effectively used because the vibration of the bone conduction speaker 31 is easily transmitted to the skull when it is placed in close contact with the cheek as shown in FIG. And while listening to the audio, if the electrode 44 and the electrode 43 on the bottom side are in close contact with the cheek, the bone conduction speaker 31 will not stop suddenly. it can.
