Description

情報端末装置Information terminal equipment
　本発明は、各種情報通信に使用される携帯電話、ＰＤＡ、ゲーム機等の情報端末装置に関する。 The present invention relates to an information terminal device such as a mobile phone, a PDA, or a game machine used for various information communications.
　近年、画像が表示される位置と音が放射される位置とを同じにした情報端末装置が実現されている。特に、携帯電話は、小型化、薄型化の要求が高く、特許文献１に記載されている携帯電話では画像を表示する表示部と音を出力するスピーカとが近接して配置されている。また、特許文献２に記載されている携帯電話では、透明なタッチパネルを設け、タッチパネルが押下されると、押下された部分が振動する。また、特許文献３に記載されている入力装置では、タッチパネルが押下された場合に、振動装置が密封された空間の空気を振動させて、タッチパネルに振動を与える。 In recent years, information terminal devices have been realized in which the position where an image is displayed and the position where sound is emitted are the same. In particular, mobile phones are highly demanded for miniaturization and thinning. In the mobile phone described in Patent Document 1, a display unit that displays an image and a speaker that outputs sound are arranged close to each other. Moreover, in the mobile phone described in Patent Document 2, a transparent touch panel is provided, and when the touch panel is pressed, the pressed part vibrates. Further, in the input device described in Patent Document 3, when the touch panel is pressed, the vibration device vibrates the air in the sealed space, and gives vibration to the touch panel.
　しかし、画像が表示される位置と音が放射される位置とを同じにすることと、透明なパネルをタッチパネルにしてこのタッチパネルが押下された場合に押下された部分に振動を与えることとを両立した情報端末装置では、ユーザが、パネルのうちスピーカを覆う部分を押すと、急激な圧力変化によってスピーカが破損してしまう。特に、小型化、薄型化の要求が強い携帯電話では、透明なパネルとスピーカとの間の密閉空間の間隔があまり確保されていないので、破損しやすい。 However, both the position where the image is displayed and the position where the sound is radiated are made the same, and when the touch panel is pressed with a transparent panel as a touch panel, vibration is applied to the pressed part. In the information terminal device, when the user presses a portion of the panel that covers the speaker, the speaker is damaged by a sudden pressure change. In particular, mobile phones that are strongly demanded for miniaturization and thinning are not easily secured because the space between the transparent panel and the speaker is not sufficiently secured.

A pattern such as a logo may be drawn on the upper surface 7A of the opaque portion 7.
　透明部６はユーザが操作できるタッチパネルである。そのタッチパネルは静電式や抵抗式のいずれの方式でもよい。上ケース２２の内部に搭載された制御部１２は、ユーザがタッチパネルである透明部６に入力操作したことを認識する。 The transparent part 6 is a touch panel that can be operated by the user. The touch panel may be either an electrostatic type or a resistance type. The control unit 12 mounted inside the upper case 22 recognizes that the user has performed an input operation on the transparent unit 6 that is a touch panel.

An operation menu icon is displayed on the image display unit 10 by the control unit 12. The operation menu icon displayed on the image display unit 10 is visible to the user outside the upper case 22 through the transparent unit 6.
　制御部１２はスピーカ１１を制御する。画像表示部１０に表示された操作メニューアイコンに対応する透明部６の部分をユーザが押圧すると、制御部１２は透明部６の押圧された部分の位置を認識する。そして、制御部１２は、認識した位置に対応する操作メニューを選択し、選択された操作メニューに対応する画像を画像表示部１０に表示する。さらに、制御部１２はスピーカ１１から出力する音を変化させる。例えば、制御部１２は、透明部６の押圧された部分の位置にかかわらず、押圧された部分でのパネル８の振動の振幅と周波数が一定になるようにスピーカ１１から出力される音を制御する。これにより、透明部６のうち、スピーカ１１から遠い部分にも振動を与えることができる。スピーカ１１からの距離に関係なく一定の強さの振動を透明部６に与えることができるので、ユーザは違和感を感じることなくタッチパネルである透明部６を操作することができる。また、制御部１２は、押圧する位置によってパネル８が振動する間隔や周期を変化させるようにスピーカ１１を制御してもよい。これによって、ユーザが透明部６に映し出された画像表示部１０の画面を視認しなくても、特定のメニューを選択したことをユーザが認識することができる。また、制御部１２は、スピーカ１１の最低共振周波数ｆ０よりも低い周波数の信号でスピーカ１１を駆動することが望ましい。これにより、パネル８が振動する際に、ユーザに音が聞こえないようにするとともに、大きな振幅と大きな時間間隔を確保して、ユーザの指先に確実に振動を伝えることができる。また、制御部１２は、スピーカ１１に入力可能な最大値よりも小さい入力信号でスピーカ１１を駆動することが望ましい。これにより、スピーカ１１の故障を防止することができる。さらに、制御部１２は、正弦波信号で前記スピーカを駆動することが望ましい。これにより、ユーザの指先に心地よい振動をスムースに確実に伝えることができる。 The control unit 12 controls the speaker 11. When the user presses the portion of the transparent portion 6 corresponding to the operation menu icon displayed on the image display portion 10, the control portion 12 recognizes the position of the pressed portion of the transparent portion 6. Then, the control unit 12 selects an operation menu corresponding to the recognized position, and displays an image corresponding to the selected operation menu on the image display unit 10. Further, the control unit 12 changes the sound output from the speaker 11. For example, the control unit 12 controls the sound output from the speaker 11 so that the amplitude and frequency of vibration of the panel 8 at the pressed part are constant regardless of the position of the pressed part of the transparent part 6. To do. Thereby, vibration can be given to a portion of the transparent portion 6 far from the speaker 11. Since the vibration with a certain strength can be given to the transparent portion 6 regardless of the distance from the speaker 11, the user can operate the transparent portion 6 which is a touch panel without feeling uncomfortable. Moreover, the control part 12 may control the speaker 11 so that the space | interval and period which the panel 8 vibrates may be changed with the position to press. Thus, the user can recognize that he / she has selected a specific menu without visually recognizing the screen of the image display unit 10 displayed on the transparent unit 6. In addition, the control unit 12 desirably drives the speaker 11 with a signal having a frequency lower than the lowest resonance frequency f0 of the speaker 11. Thus, when the panel 8 vibrates, it is possible to prevent the user from hearing a sound, and to ensure a large amplitude and a large time interval, thereby reliably transmitting the vibration to the user's fingertip. Further, it is desirable that the control unit 12 drives the speaker 11 with an input signal smaller than the maximum value that can be input to the speaker 11. Thereby, failure of the speaker 11 can be prevented. Furthermore, it is desirable that the control unit 12 drives the speaker with a sine wave signal. Thereby, a pleasant vibration can be smoothly and reliably transmitted to the user's fingertip.
　スピーカ１１が外部から視認可能になると、ユーザは、パネルのうちスピーカを覆う部分を、ボタンと間違えて押したり、気になって押してしまったりしてしまう。パネル８のうちスピーカ１１を覆う部分が押されると、急激な圧力変化によってスピーカ１１が破損してしまう。特に、小型化、薄型化の要求が強い情報携帯端末１では、透明なパネルとスピーカ１１との間の密閉空間の間隔があまり確保されていないので、破損しやすい。 When the speaker 11 is visible from the outside, the user pushes the part of the panel that covers the speaker by mistake as a button or pushes it. If the part which covers the speaker 11 among the panels 8 is pushed, the speaker 11 will be damaged by rapid pressure change. In particular, in the portable information terminal 1 that is strongly demanded to be reduced in size and thickness, the clearance between the transparent panel and the speaker 11 is not secured so much and is easily damaged.
　不透明部７は塗装や印刷等の手段で不透明にされてもよい。不透明部７がスピーカ１１を覆っているので、ユーザに見せる必要のないスピーカ１１が外部から隠される。これにより、ユーザが、パネル８のうちスピーカ１１を覆う部分をボタンと間違えて押したり、スピーカ１１が気になってその部分を押してしまったりすることを防止することができる。スピーカ１１を覆うパネル８がユーザに押されない不透明部７であるので、急激な圧力変化によってスピーカ１１が破損することを防止し、スピーカ１１の品質を維持することができる。 The opaque portion 7 may be made opaque by means such as painting or printing. Since the opaque portion 7 covers the speaker 11, the speaker 11 that does not need to be shown to the user is hidden from the outside. Thereby, it can prevent that a user presses the part which covers the speaker 11 among the panels 8 by mistake with a button, or the speaker 11 cares about and presses the part. Since the panel 8 that covers the speaker 11 is the opaque portion 7 that is not pressed by the user, the speaker 11 can be prevented from being damaged by a sudden pressure change, and the quality of the speaker 11 can be maintained.
　スピーカ１１から放出される音は、透明部６や不透明部７からなるパネル８を介して上ケース２２の外部に放出される。したがって、ユーザは、透明部６で画像を視認できるとともに、透明部６から音が放出されるように感じることができる。 The sound emitted from the speaker 11 is emitted to the outside of the upper case 22 through the panel 8 including the transparent portion 6 and the opaque portion 7. Therefore, the user can visually recognize the image with the transparent portion 6 and can feel that sound is emitted from the transparent portion 6.
