図３は、本実施例の携帯端末機器１０１と着せ替えパネル１０３の構成を示すブロック図である。図３に示すように、携帯端末本体１０１内には、ユーザが操作可能なキー２５、キー操作に応じた操作内容や映像を表示するＬＣＤ２４、キー操作によるユーザからの命令を処理するＣＰＵ（Central Processing Unit）２３、音データなどのユーザデータを保持するメモリ２２、ＣＰＵ２３により処理された命令を物理的に処理させるための制御回路２１、音データを復号するためのデコーダ１１、デコーダ１１で復号されたデータをアナログ変換するＤ／Ａ（Digital/Analog）コンバータ１２、アナログ変換されたアナログデータの振幅（つまり、音量）を調整するボリューム回路１３、アナログデータを増幅させるスピーカアンプ１４、音声等を機器外に出力する内蔵スピーカ１５、内蔵スピーカ１５と外部スピーカ１７とを切り替えるためのアナログＳＷ（Switch）１６、アナログＳＷ１６から分岐し、外部スピーカ１７と接続するための端子Ａ、が備えられている。また、着せ替えパネル１０３には、端子Ａと接続するための端子Ｂ、内蔵スピーカ１５と同等もしくはより最大許容定格の大きいスピーカ１７、が備えられている。   FIG. 3 is a block diagram illustrating a configuration of the mobile terminal device 101 and the dressing panel 103 according to the present embodiment. As shown in FIG. 3, in the mobile terminal body 101, a key 25 that can be operated by the user, an LCD 24 that displays operation contents and video according to the key operation, and a CPU (Central Processing Unit) that processes commands from the user by key operation. Processing Unit) 23, memory 22 for storing user data such as sound data, control circuit 21 for physically processing instructions processed by CPU 23, decoder 11 for decoding sound data, and decoder 11 for decoding A D / A (Digital / Analog) converter 12 that converts analog data into analog data, a volume circuit 13 that adjusts the amplitude (that is, volume) of analog data after analog conversion, a speaker amplifier 14 that amplifies analog data, audio, and the like Built-in speaker 15 that outputs to the outside, an analog for switching between built-in speaker 15 and external speaker 17 A terminal A for branching from the switch SW 16 and the analog SW 16 and connecting to the external speaker 17 is provided. The dressing panel 103 includes a terminal B for connection to the terminal A and a speaker 17 that is equivalent to or larger in maximum allowable rating than the built-in speaker 15.

なお、図３、図７では図示を省略しているが、ステレオスピーカ方式に対応するためには、Ｄ／Ａコンバータ１２、ボリューム回路１３、スピーカアンプ１４、アナログＳＷ１６、端子Ａ、及び端子Ｂはそれぞれ、Ｒ（ライト）側とＬ（レフト）側を備える必要があり、これは一般的な周知技術である。   Although not shown in FIGS. 3 and 7, in order to support the stereo speaker system, the D / A converter 12, the volume circuit 13, the speaker amplifier 14, the analog SW 16, the terminal A, and the terminal B are Each needs to have an R (right) side and an L (left) side, which is a common and well-known technique.

次に、図３、図４、及び図５を参照しながら、本実施例の動作について説明する。   Next, the operation of this embodiment will be described with reference to FIG. 3, FIG. 4, and FIG.

図４は、ユーザ操作による音量設定値と、スピーカ出力レベル（つまり、音圧もしくは音量）との関係を示した相関図である。図４では、内蔵スピーカの使用時に比べ、外部スピーカの使用時は、スピーカの最大定格の許容範囲を大きくすることが可能なため、より大きな音量を設定できることを示している。   FIG. 4 is a correlation diagram showing a relationship between a volume setting value by a user operation and a speaker output level (that is, sound pressure or volume). FIG. 4 shows that a larger volume can be set because the allowable range of the maximum rating of the speaker can be increased when using an external speaker than when using an internal speaker.

図１、図３に示すキー２５からのキー操作により選択された音量設定値は、制御回路２１を介し、ＣＰＵ２３にて、適切なスピーカボリューム値へ変換され、ボリューム回路１３へ設定される。なお、音量設定は、そのハードウェアの構成によっては、ボリューム回路１３のみの設定ではなく、音声経路の途中で他手段でも構成することは一般的に知られているので、この限りではない。   The volume setting value selected by the key operation from the key 25 shown in FIGS. 1 and 3 is converted into an appropriate speaker volume value by the CPU 23 via the control circuit 21 and set in the volume circuit 13. Note that the volume setting is not limited to the setting of only the volume circuit 13 depending on the configuration of the hardware, and is generally configured by other means in the middle of the audio path.

そして、図５に示すように、着せ替えパネル１０３が携帯端末機器１０１に装着された後（ステップＳ１）、ユーザによって外部スピーカ１７に切り替える操作（ユーザは、所定のメニュー画面等で、キー２５の操作により「外部スピーカへ切り替え」を選択する）が行われたかどうかを判断する（ステップＳ２）。外部スピーカへの切り替え操作が行われた場合（ステップＳ２／ＹＥＳ）、アナログＳＷ１６を外部スピーカ１７へ切り替える。その後、ユーザによって音量設定操作（ユーザは、所定のメニュー画面等で、キー２５の操作により外部スピーカ１７から出力される音量の値を設定する）が行われたかどうかを判断する（ステップＳ４）。音量設定操作が行われた場合（ステップＳ４／ＹＥＳ）、設定された音量設定値に調整制御する（ステップＳ５）。   Then, as shown in FIG. 5, after the dress-up panel 103 is attached to the mobile terminal device 101 (step S <b> 1), the user switches to the external speaker 17 (the user selects the key 25 on a predetermined menu screen or the like). It is determined whether or not “select to switch to external speaker” has been performed (step S2). When the switching operation to the external speaker is performed (step S2 / YES), the analog SW 16 is switched to the external speaker 17. Thereafter, it is determined whether or not the user has performed a volume setting operation (the user sets a volume value output from the external speaker 17 by operating the key 25 on a predetermined menu screen or the like) (step S4). When the volume setting operation is performed (step S4 / YES), adjustment control is performed to the set volume setting value (step S5).

よって、内蔵スピーカ１５利用時は例えば音量設定が６までしか設定できない場合でも、外部スピーカ１７へ切り替えることにより、音量設定が例えば９まで選択できるようになる。   Therefore, when the built-in speaker 15 is used, even when the volume setting can be set only up to 6, for example, by switching to the external speaker 17, the volume setting can be selected up to 9, for example.

従来、例えば上記特許文献１記載の発明では、背面パネルの大きさが携帯電話機の筐体の大きさに合わせたものであるので、背面パネルに設置可能なスピーカの大きさが、携帯電話機の背面の面積内に限定されてしまい、音楽やテレビの音を聴くための音量や音質は不十分となる可能性があったが、本実施例によれば、実装上の制約が少ない着せ替えパネルにスピーカを構成するため、実装するスピーカの大きさは携帯端末機器の筐体の面積に制限されることがなく、また、携帯端末機器自体に大型スピーカを持たせずに済み、さらには、携帯端末機器本体を大型化せずに、高出力の音を聞くことができる。特に、携帯端末機器で音楽を聴いたり、テレビを見たりする場合、臨場感のある音を聞くことができるようになることや、着せ替えパネルのカスタマイズ化により、エンドユーザの利用方法にバリエーションが広がるという効果が得られる。また、本実施例の着せ替えパネルは、実装上の制約が携帯端末機器に比べ少ないことから、着せ替えパネルに周波数別の複数のスピーカを備えることで、より高音質な音を楽しむことも可能となる。   Conventionally, in the invention described in Patent Document 1, for example, the size of the rear panel matches the size of the casing of the mobile phone. The volume and sound quality for listening to music and TV sound may be insufficient, but according to the present embodiment, the dressing panel has few restrictions on mounting. Since the speaker is configured, the size of the speaker to be mounted is not limited by the area of the casing of the mobile terminal device, and it is not necessary to have a large speaker in the mobile terminal device itself. You can hear high-powered sound without increasing the size of the device. In particular, when listening to music on a mobile terminal device or watching TV, there will be variations in how the end user will be able to hear realistic sounds and by customizing the dress-up panel. The effect of spreading is obtained. In addition, since the dress-up panel of this embodiment has fewer restrictions on mounting than mobile terminal devices, it is possible to enjoy higher-quality sound by providing multiple speakers for different frequencies on the dress-up panel. It becomes.

また、従来、ヘッドセットコネクタへ接続可能な外部スピーカが実用化されているが、ヘッドセットアンプはスピーカアンプに比べ出力レベルが小さいため、外部スピーカ側にアンプが必要であった。そのため、外部スピーカ側に電源回路を設けてアンプで増幅しなければいけなかったが、本実施例のスピーカつき着せ替えパネルには、スピーカとその配線のみで構成されるため、能動措素子を持たない。そのため、本実施例では、容易で安価な高出力のスピーカを構成した着せ替えパネルを提供することができる。また、本実施例によれば、携帯端末機器を持ち運んでいる場合には通常の着せ替えパネルを装着し、自宅など落ちついた場所ではスピーカ付き着せ替えパネルに着せ替えて、高出力スピーカで音楽やテレビを楽しむといったことが可能となる。   Conventionally, external speakers that can be connected to the headset connector have been put into practical use. However, since the headset amplifier has a lower output level than the speaker amplifier, an amplifier is required on the external speaker side. For this reason, a power circuit must be provided on the external speaker side and amplified by an amplifier. However, since the dressing panel with a speaker of this embodiment is composed only of a speaker and its wiring, it has an active device. Absent. Therefore, in this embodiment, it is possible to provide a dress-up panel that constitutes an easy and inexpensive high-power speaker. In addition, according to the present embodiment, when carrying a mobile terminal device, a normal dressing panel is attached, and in a calm place such as at home, a dressing panel with a speaker is worn, and music or You can enjoy TV.

また、従来、携帯端末機器のスピーカが筐体の背面に実装されているような場合（又は、上記特許文献１記載の発明のように、スピーカが背面パネルに設置される場合）、例えばＴＶ電話やＴＶ視聴等のＴＶ機能を使用する時に、正面側に備えられた表示画面に表示される映像と、背面側に備えられたスピーカから出力される音とが、正反対の方向に出力されてしまうため、音声が聞こえづらいという問題があったが、本実施例の着せ替えパネルを使用することで、携帯端末機器本体（又は、背面パネル）の実装に依存せずに、スピーカの向きを任意の方向に実装できるため、ＴＶ機能を使用する時にも音声が聞き取りやすいという効果もある。   Conventionally, when a speaker of a mobile terminal device is mounted on the back of a housing (or when the speaker is installed on the back panel as in the invention described in Patent Document 1), for example, a video phone When using TV functions such as TV viewing and TV viewing, the video displayed on the display screen provided on the front side and the sound output from the speaker provided on the back side are output in opposite directions. Therefore, there was a problem that it was difficult to hear the sound. However, by using the dress-up panel of this embodiment, the orientation of the speaker can be set to an arbitrary direction without depending on the mounting of the mobile terminal device body (or the rear panel). Since it can be mounted in the direction, there is also an effect that it is easy to hear sound even when using the TV function.

本発明の実施例２について、図６及び図７を参照して以下に説明する。
図６は、実施例２の着せ替えパネル１０３の外観イメージ図である。図６に示すように、本実施例の着せ替えパネル１０３は、実施例１の着せ替えパネルの構成（図２参照）に加え、携帯端末機器１０１が着せ替えパネル１０３の装着を自動的に検出する際に用いられる検出用端子Ｄ、Ｆを備えることを特徴とする。なお、本実施例の携帯端末機器１０１には、検出用端子Ｄ、Ｆと接続可能な検出用端子Ｃ、Ｅを備える。 A second embodiment of the present invention will be described below with reference to FIGS.
FIG. 6 is an external view of the dressing panel 103 according to the second embodiment. As shown in FIG. 6, in the dress-up panel 103 of this embodiment, in addition to the configuration of the dress-up panel of Embodiment 1 (see FIG. 2), the mobile terminal device 101 automatically detects the wearing of the dress-up panel 103. It is characterized by comprising detection terminals D and F used in the process. Note that the mobile terminal device 101 of this embodiment includes detection terminals C and E that can be connected to the detection terminals D and F.

図７は、本実施例の携帯端末機器１０１と着せ替えパネル１０３の構成を示すブロック図である。図７に示すように、実施例１と異なる点を説明すると、携帯端末機器１０１に具備される端子ＥはＧＮＤ（GrouND）に接続されている。また、端子Ｃは、端子Ｃの電位に基づいて着せ替えパネル１０３の装着の有無を自動検出させるため、制御回路２１に接続される。着せ替えパネル１０３には、端子Ｃと接続される端子Ｄと、端子Ｅと接続される端子Ｆとを具備し、端子Ｄと端子Ｆは電気的に接続されている。   FIG. 7 is a block diagram illustrating a configuration of the mobile terminal device 101 and the dress-up panel 103 according to the present embodiment. As illustrated in FIG. 7, the differences from the first embodiment will be described. A terminal E included in the mobile terminal device 101 is connected to GND (GrouND). Further, the terminal C is connected to the control circuit 21 in order to automatically detect whether or not the dressing panel 103 is mounted based on the potential of the terminal C. The dressing panel 103 includes a terminal D connected to the terminal C and a terminal F connected to the terminal E, and the terminal D and the terminal F are electrically connected.

図８は、実施例２の動作を示すフローチャートである。
着せ替えパネル１０３が携帯端末機器１０１に装着されると、図７に示すように、端子Ｃと端子Ｄ、端子Ｅと端子Ｆがそれぞれ接続されるが、これら各端子同士の接続に基づいて、制御回路２１が、着せ替えパネル１０３が携帯端末機器１０１に装着されたかどうかを検出する（ステップＳ１１）。着せ替えパネル１０３の装着を検出した場合（ステップＳ１１／ＹＥＳ）、制御回路２１はアナログＳＷ１６に外部スピーカ１７に切り替えるように要求し、外部スピーカ１７に接続されるように切り替わる（ステップＳ１２）。その後、ユーザによって音量設定操作（ユーザは、所定のメニュー画面等で、キー２５の操作により外部スピーカ１７から出力される音量の値を設定する）が行われたかどうかを判断する（ステップＳ１３）。音量設定操作が行われた場合（ステップＳ１３／ＹＥＳ）、設定された音量設定値に調整制御する（ステップＳ１４）。 FIG. 8 is a flowchart illustrating the operation of the second embodiment.
When the dress-up panel 103 is attached to the portable terminal device 101, as shown in FIG. 7, the terminal C and the terminal D and the terminal E and the terminal F are connected, respectively. Based on the connection between these terminals, The control circuit 21 detects whether the dress-up panel 103 is attached to the mobile terminal device 101 (step S11). When the attachment of the dressing panel 103 is detected (step S11 / YES), the control circuit 21 requests the analog SW 16 to switch to the external speaker 17 and switches to be connected to the external speaker 17 (step S12). Thereafter, it is determined whether or not the user has performed a volume setting operation (the user sets a volume value output from the external speaker 17 by operating the key 25 on a predetermined menu screen or the like) (step S13). When the volume setting operation is performed (step S13 / YES), adjustment control is performed to the set volume setting value (step S14).

よって、内蔵スピーカ１５利用時は例えば音量設定が６までしか設定できない場合でも、外部スピーカ１７へ切り替えることにより、音量設定が例えば９まで選択できるようになる。
なお、音量設定上限値を、その回路構成により任意に設計できることは、ここでは敢えて言及しない。 Therefore, when the built-in speaker 15 is used, even when the volume setting can be set only up to 6, for example, by switching to the external speaker 17, the volume setting can be selected up to 9, for example.
It should be noted that the volume setting upper limit value can be arbitrarily designed according to the circuit configuration, and is not mentioned here.

本発明の実施例３について、図９を参照して説明する。
図９に示すように、着せ替えパネル１０３の外部スピーカ１７の実装位置を変更し、着せ替えパネル１０３を小型にしたことを特徴とする。この着せ替えパネル１０３の機能、動作は、上記実施例１及び２と同様である。 A third embodiment of the present invention will be described with reference to FIG.
As shown in FIG. 9, the mounting position of the external speaker 17 on the dressing panel 103 is changed to make the dressing panel 103 smaller. The function and operation of the dress-up panel 103 are the same as those in the first and second embodiments.
