制御部２１３は、給電用プラグ２１２を介してＤＡＰ１１とデータ送受信を行う。例えば、ＤＡＰ１１から音声データを受信し、切替部２１４に供給する。切替部２１４に供給された音声データは、サウンドユニット２１５または無線通信部２１７に供給される。制御部２１３は、切替部２１４の切り替え態様を制御する。例えば、充電アダプタ２１にユーザ操作用の操作部（スイッチ等）を設けた場合、ユーザがスピーカ２１６から音声を放音するように設定指示すると、制御部２１３は切替部２１４に音声データをサウンドユニット２１５に供給するよう指示する。また、後述のように、通常時は音声データをサウンドユニット２１５に供給し、無線通信部２１７が他の電子機器と通信を確立した場合に音声データを他の電子機器に供給するように構成することも可能である。   The control unit 213 performs data transmission / reception with the DAP 11 via the power supply plug 212. For example, audio data is received from the DAP 11 and supplied to the switching unit 214. The audio data supplied to the switching unit 214 is supplied to the sound unit 215 or the wireless communication unit 217. The control unit 213 controls the switching mode of the switching unit 214. For example, when the operation unit (switch or the like) for user operation is provided in the charging adapter 21, when the user gives a setting instruction to emit sound from the speaker 216, the control unit 213 sends the sound data to the switching unit 214 as a sound unit. 215 is instructed to supply. Further, as will be described later, the audio data is normally supplied to the sound unit 215, and the audio data is supplied to the other electronic device when the wireless communication unit 217 establishes communication with the other electronic device. It is also possible.

サウンドユニット２１５に供給された音声データは、デコード処理、アナログ変換がされ、増幅された音声信号としてスピーカ２１６に供給され、音声として放音される。無線通信部２１７に供給された音声データは、当該無線通信部２１７により他の電子機器（ＰＣ等）に供給される。ＰＣ等に供給された音声データは、その電子機器において放音される。   The audio data supplied to the sound unit 215 is subjected to decoding processing and analog conversion, supplied to the speaker 216 as an amplified audio signal, and emitted as audio. The audio data supplied to the wireless communication unit 217 is supplied to another electronic device (such as a PC) by the wireless communication unit 217. Audio data supplied to a PC or the like is emitted by the electronic device.

無線通信部２１７は、Ｂｌｕｅｔｏｏｔｈ、Ｗｉ−Ｆｉ（登録商標）、ＦＭトランスミッタ等の通信機能を有するモジュールであり、上記のようにＤＡＰ１１から制御部２１３および切替部２１４を介して受信したデータを他の電子機器に送信する。また、他の電子機器から受信したデータを、切替部２１４および制御部２１３を介してＤＡＰ１１に送信する。   The wireless communication unit 217 is a module having a communication function such as Bluetooth, Wi-Fi (registered trademark), FM transmitter, etc., and receives data received from the DAP 11 via the control unit 213 and the switching unit 214 as described above. Send to electronic device. In addition, data received from another electronic device is transmitted to the DAP 11 via the switching unit 214 and the control unit 213.

無線通信部２１７は、上記の通信機能を用いて他の電子機器と通信を確立した場合、制御部２１３にその旨を示す情報を送信する。また、他の電子機器と通信できない場合（通信可能エリアに他の電子機器が存在しない、ネゴシエーションできない、等）、制御部２１３にその旨を示す情報を送信する。制御部２１３は、他の電子機器と通信を確立した旨を示す情報を受信した場合、音声データを無線通信部２１７に送信するように切替部２１４に指示する。これによりスピーカ２１６の放音を停止する。また、他の電子機器と通信を確立できない旨を示す情報を受信した場合、音声データをサウンドユニット２１５に送信するように切替部２１４に指示する。この場合、通常時は充電アダプタの付属スピーカで楽音を聞くことができ、他の電子機器との接続が確立された場合には他の電子機器を用いてより高音質で楽音を聞くことができる。よって、ユーザはどのような場所でも楽音を聞くことができる。   When the wireless communication unit 217 establishes communication with another electronic device using the communication function, the wireless communication unit 217 transmits information indicating that to the control unit 213. When communication with another electronic device is not possible (no other electronic device exists in the communicable area, negotiation is not possible, etc.), information indicating that is transmitted to the control unit 213. When the control unit 213 receives information indicating that communication with another electronic device has been established, the control unit 213 instructs the switching unit 214 to transmit the audio data to the wireless communication unit 217. Thereby, the sound emission of the speaker 216 is stopped. In addition, when information indicating that communication cannot be established with another electronic device is received, the switching unit 214 is instructed to transmit audio data to the sound unit 215. In this case, you can usually listen to the music with the speaker attached to the charging adapter, and if you have established a connection with another electronic device, you can listen to the music with higher quality using the other electronic device. . Therefore, the user can listen to the musical sound anywhere.

制御部２１３は、上記のような動作を行うため、充電池２１８またはＤＡＰ１１から電力供給を受ける。ＤＡＰ１１から電力供給を受ける場合、充電用ポート１１２および給電用プラグ２１２を介して電力供給を受ける（３．５Ｖライン）。   The control unit 213 receives power supply from the rechargeable battery 218 or the DAP 11 in order to perform the operation as described above. When receiving power supply from the DAP 11, the power supply is received via the charging port 112 and the power supply plug 212 (3.5V line).

ここで、制御部２１３は、充電池２１８の容量に応じて、充電池２１８からの電力供給とＤＡＰ１１からの電力供給を切り替える。すなわち、制御部２１３は、定常時は充電池２１８から電力供給を受けるように設定するとともに充電池２１８の充電量を監視しており、この充電量が所定容量以下となった場合にＤＡＰ１１から電力供給を受けるように設定する。   Here, the control unit 213 switches between power supply from the rechargeable battery 218 and power supply from the DAP 11 according to the capacity of the rechargeable battery 218. That is, the control unit 213 is set to receive power from the rechargeable battery 218 in a steady state and monitors the charge amount of the rechargeable battery 218. When the charge amount becomes a predetermined capacity or less, the control unit 213 receives power from the DAP11. Set to receive supply.

さらに、制御部２１３は、充電池２１８が所定容量以下となった場合、音声データを受信している途中であるかを判断し、次に音声データが途切れるまで切り替えを待機する。音声データが途切れた場合に電源供給を切り替える。   Furthermore, when the rechargeable battery 218 becomes less than or equal to the predetermined capacity, the control unit 213 determines whether the audio data is being received and waits for switching until the audio data is interrupted next time. Switch power supply when audio data is interrupted.

このように、充電アダプタ２１を駆動するための内蔵充電池２１８が切れる間際に、音声データの供給が途切れている間にＤＡＰ１１から電力供給を受けるように切り替えることで、切り替え時のノイズ発生を防止することができる。なお、音声データの供給が途切れる場合とは、ＤＡＰ１１の電源がオフされたとき、再生曲が変更されたとき（曲間）、等である。   In this way, when the built-in rechargeable battery 218 for driving the charging adapter 21 is about to run out, switching to receive power from the DAP 11 while the supply of audio data is interrupted prevents the occurrence of noise during switching. can do. Note that the case where the supply of audio data is interrupted is when the power of the DAP 11 is turned off, when the reproduction music is changed (between music), or the like.

次に、図３は、電子機器システムの他の例を示す外観図である。図３に示す電子機器システム２は、ＤＡＰ１１と、ＤＡＰ１１に接続される充電アダプタ４１と、充電アダプタ４１を保持する充電台５１と、からなる。   Next, FIG. 3 is an external view showing another example of the electronic device system. The electronic device system 2 shown in FIG. 3 includes a DAP 11, a charging adapter 41 connected to the DAP 11, and a charging stand 51 that holds the charging adapter 41.

なお、図３に示す電子機器システムにおいて、充電アダプタ４１の内部構成は上記充電アダプタ２１と同様であり、同一の機能を有する。そのため、充電アダプタ４１の内部構成のブロック図を省略し、その説明を省略する。   In the electronic device system shown in FIG. 3, the internal configuration of the charging adapter 41 is the same as that of the charging adapter 21 and has the same function. Therefore, the block diagram of the internal configuration of the charging adapter 41 is omitted, and the description thereof is omitted.

充電アダプタ４１は、上記充電アダプタ２１と同様、高さ方向に長い薄型の略直方体形状の筐体からなり、筐体下部側の一部が前面方向に張り出したＬ字型形状となっている。この前面方向に張り出した部分（受け部）４３の上面側に給電用プラグ４１２が設けられている。また、充電アダプタ４１では、この受け部４３の側面側の２箇所にプラス側の受電用接触端子４１１およびマイナス側の受電用接触端子４１３が設けられている。この受け部４３の上面と、筐体の前面部４２でＤＡＰ１１を保持するようになっている。なお、同図では、左側面（紙面右側）の１箇所にマイナス側の受電用接触端子４１３が設けられ、右側面の１箇所（紙面左側で図示していない箇所）にプラス側の受電用接触端子４１１が設けられている。   Like the charging adapter 21, the charging adapter 41 is formed of a thin, substantially rectangular parallelepiped housing that is long in the height direction, and has an L-shape in which a part on the lower side of the housing projects in the front direction. A power supply plug 412 is provided on the upper surface side of the portion (receiving portion) 43 protruding in the front direction. Further, in the charging adapter 41, a positive power receiving contact terminal 411 and a negative power receiving contact terminal 413 are provided at two positions on the side surface side of the receiving portion 43. The DAP 11 is held by the upper surface of the receiving portion 43 and the front surface portion 42 of the housing. In the figure, a negative power receiving contact terminal 413 is provided at one location on the left side (right side of the paper), and a positive power receiving contact is provided at one location on the right side (not shown on the left side of the paper). A terminal 411 is provided.

また、充電アダプタ２１と同様、筐体の前面部４２には、桶形状にくり抜いたくり抜き部４４が設けられており、この桶形状のくり抜き部４４に円盤部４５がらせん挿入（スクリュー）されるようになっている。円盤部４５をらせん挿入することで筐体前面の高さ（当該円盤部４５の前面方向への張り出し具合）を自由に設定することができるようになっている。これにより、ＤＡＰ１１を強固に保持することができる。   Similarly to the charging adapter 21, the front surface portion 42 of the housing is provided with a punched-out portion 44 cut into a bowl shape, and the disk portion 45 is spirally inserted (screwed) into the punched-out portion 44 of the bowl shape. It is like that. By inserting the disk portion 45 in a spiral manner, the height of the front surface of the housing (how the disk portion 45 projects in the front direction) can be freely set. Thereby, DAP11 can be held firmly.

充電台５１は、充電アダプタ４１の筐体が収まる中空構造の円環形状の筐体からなる。円環形状の筐体の外側面には、延長部５１２が設けられており、この延長部５１２に電源ケーブル５１５が接続されている。この電源ケーブル５１５を宅内コンセントに接続することで、電力供給を受けることができる。宅内コンセントから受けた電力は、上記接触端子を介して充電アダプタ４１に供給され、充電アダプタ４１からＤＡＰ１１に供給されるようになっている。   The charging stand 51 is formed of an annular casing having a hollow structure in which the casing of the charging adapter 41 is accommodated. An extension part 512 is provided on the outer surface of the annular casing, and a power cable 515 is connected to the extension part 512. By connecting the power cable 515 to a home outlet, power can be supplied. The electric power received from the home outlet is supplied to the charging adapter 41 via the contact terminal, and is supplied from the charging adapter 41 to the DAP 11.

充電台５１は、円環部分の内側面の１箇所にプラス側の給電用接触端子５１１が設けられ、その反対側の内側面にマイナス側の給電用接触端子５１３が設けられている。これらの給電用接触端子が設けられている箇所は、内側面が平面上にえぐられており、この平面部分に上記直方体形状の充電アダプタ４１がはめこまれる。そのため、充電アダプタ４１を強固に保持するとともに、受電用接触端子４１１と給電用接触端子５１１が接触し、受電用接触端子４１３と給電用接触端子５１３が接触するようになっている。なお、充電アダプタ４１は、上下方向には容易に移動させることが可能である。   The charging stand 51 is provided with a plus-side power supply contact terminal 511 at one location on the inner surface of the annular portion, and a minus-side power supply contact terminal 513 on the opposite inner surface. The locations where these contact terminals for power feeding are provided have an inner surface that is cut out on a plane, and the rectangular parallelepiped charging adapter 41 is fitted into this plane portion. Therefore, the charging adapter 41 is firmly held, the power receiving contact terminal 411 and the power feeding contact terminal 511 are in contact with each other, and the power receiving contact terminal 413 and the power feeding contact terminal 513 are in contact with each other. Note that the charging adapter 41 can be easily moved in the vertical direction.

次に、図４は、電子機器システムのさらに他の例を示す外観図である。図４に示す電子機器システム３は、ＤＡＰ１１と、ＤＡＰ１１に接続される充電アダプタ６１と、充電アダプタ６１を保持する充電台７１と、からなる。   Next, FIG. 4 is an external view showing still another example of the electronic device system. The electronic device system 3 illustrated in FIG. 4 includes a DAP 11, a charging adapter 61 connected to the DAP 11, and a charging stand 71 that holds the charging adapter 61.

なお、図４に示す電子機器システム３において、充電アダプタ６１の内部構成は上記充電アダプタ２１、充電アダプタ４１と同様であり、同一の機能を有する。そのため、充電アダプタ６１の内部構成のブロック図を省略し、その説明を省略する。   In the electronic device system 3 shown in FIG. 4, the internal configuration of the charging adapter 61 is the same as that of the charging adapter 21 and the charging adapter 41, and has the same function. Therefore, the block diagram of the internal configuration of the charging adapter 61 is omitted, and the description thereof is omitted.

充電アダプタ６１は、幅方向に長い薄型の略直方体形状の筐体からなり、上面に給電用プラグ（不図示）が設けられている。同図に示す電子機器システム３では、ＤＡＰ側の受電用ポートと充電アダプタ側の給電用プラグとの接続によりＤＡＰと充電アダプタが保持されるようになっている。そのため、筐体がコンパクトで持ち運びし易くなっている。   The charging adapter 61 is formed of a thin, substantially rectangular parallelepiped casing that is long in the width direction, and a power supply plug (not shown) is provided on the upper surface. In the electronic device system 3 shown in the figure, the DAP and the charge adapter are held by connecting the power reception port on the DAP side and the power supply plug on the charge adapter side. Therefore, the housing is compact and easy to carry.

また、充電アダプタ６１には、側面のうちいずれか１箇所にプラス側の受電用接触端子６１１が設けられており、反対側の側面にマイナス側の受電用接触端子６１３が設けられている。また、これらの受電用接触端子は、高さ方向で異なる位置に設けられている。なお、プラス側の受電用接触端子６１１とマイナス側の受電用接触端子６１３は、筐体の高さ方向で異なる位置に設けられていればよく、側面の同じ側に設けられていてもよい。   Further, the charging adapter 61 is provided with a positive power receiving contact terminal 611 at any one of the side surfaces, and a negative power receiving contact terminal 613 is provided on the opposite side surface. Further, these power receiving contact terminals are provided at different positions in the height direction. Note that the plus-side power receiving contact terminal 611 and the minus-side power receiving contact terminal 613 may be provided at different positions in the height direction of the housing, or may be provided on the same side of the side surface.

充電台７１は、充電アダプタ６１の筐体が収まる中空構造の円環形状の筐体からなる。円環形状の筐体の外側面には、延長部７１２が設けられており、この延長部７１２に電源ケーブル７１５が接続されている。この電源ケーブル７１５を宅内コンセントに接続することで、電力供給を受けることができる。宅内コンセントから受けた電力は、上記接触端子を介して充電アダプタ６１に供給され、充電アダプタ６１からＤＡＰ１１に供給されるようになっている。   The charging stand 71 is formed of a hollow ring-shaped casing in which the casing of the charging adapter 61 is accommodated. An extension 712 is provided on the outer surface of the annular housing, and a power cable 715 is connected to the extension 712. By connecting the power cable 715 to a home outlet, power can be supplied. The electric power received from the home outlet is supplied to the charging adapter 61 via the contact terminal, and is supplied from the charging adapter 61 to the DAP 11.

充電台７１は、円環部分の内側面の１箇所にプラス側の給電用接触端子７１１が設けられ、その反対側の内側面にマイナス側の給電用接触端子７１３が設けられている。これらの給電用接触端子は、円環の内側面に沿って設けられている。また、プラス側の給電用接触端子７１１と、マイナス側の給電用接触端子７１３とは、高さ方向で異なる位置に設けられている。同図の例では、充電アダプタ６１のプラス側の受電用接触端子６１１が高さ方向で上側に設けられ、マイナス側の受電用接触端子６１３が高さ方向の下側に設けられている。そのため、充電台７１のプラス側の給電用接触端子７１１も高さ方向で上側に設けられ、マイナス側の給電用接触端子７１３も高さ方向で下側に設けられている。   The charging stand 71 is provided with a positive-side power supply contact terminal 711 at one location on the inner surface of the annular portion, and a negative-side power supply contact terminal 713 on the opposite inner surface. These power supply contact terminals are provided along the inner surface of the ring. Further, the positive-side power supply contact terminal 711 and the negative-side power supply contact terminal 713 are provided at different positions in the height direction. In the example of the figure, the positive power receiving contact terminal 611 of the charging adapter 61 is provided on the upper side in the height direction, and the negative power receiving contact terminal 613 is provided on the lower side in the height direction. Therefore, the plus-side power supply contact terminal 711 of the charging stand 71 is also provided on the upper side in the height direction, and the minus-side power supply contact terminal 713 is also provided on the lower side in the height direction.

そのため、充電アダプタ６１を保持するとともに、受電用接触端子と給電用接触端子が接触するようになっている。また、プラス側の端子が上側、マイナス側の端子が下側となり、高さが異なるような接触端子となっていることで、プラス側受電用接触端子６１１とマイナス側給電用接触端子７１３が接触することなく、同様にマイナス側受電用接触端子６１３とプラス側給電用接触端子７１１が接触することもない。そのため、充電アダプタ６１をどのような載せ方をしてもショートすることがない。なお、プラス側受電用接触端子６１１とマイナス側受電用接触端子６１３が側面の同じ側に設けられている場合、プラス側給電用接触端子７１１とマイナス側給電用接触端子７１３も内側面の同じ側に設けられているものとする。   Therefore, while holding the charging adapter 61, the power receiving contact terminal and the power feeding contact terminal come into contact with each other. Further, the positive terminal is the upper side, the negative terminal is the lower side, and the contact terminals have different heights so that the positive power receiving contact terminal 611 and the negative power feeding contact terminal 713 are in contact with each other. Similarly, the minus-side power receiving contact terminal 613 and the plus-side power feeding contact terminal 711 are not in contact with each other. Therefore, there is no short circuit regardless of how the charging adapter 61 is placed. When the plus side power receiving contact terminal 611 and the minus side power receiving contact terminal 613 are provided on the same side of the side surface, the plus side power feeding contact terminal 711 and the minus side power feeding contact terminal 713 are also on the same side of the inner side surface. Shall be provided.

以上のように、本実施形態の電子機器システムでは、ＤＡＰと充電台との間に、給電用プラグと受電用接触端子を備えた充電アダプタを設け、ＤＡＰをこの充電アダプタに接続しておくことで、単に載せ置きするだけの操作で充電をすることができる。また、充電アダプタに無線通信機能を内蔵しておくことで、ＤＡＰを充電台に載せなくともＰＣと通信を行うことができる。   As described above, in the electronic device system of the present embodiment, a charging adapter including a power feeding plug and a power receiving contact terminal is provided between the DAP and the charging stand, and the DAP is connected to the charging adapter. Thus, it can be charged by simply placing it. In addition, by incorporating a wireless communication function in the charging adapter, communication with a PC can be performed without placing the DAP on the charging stand.

なお、充電アダプタと充電台の形状は上記例に限るものではない。例えば、充電アダプタは、ＤＡＰの全体を覆うようなケース状の筐体とすることも可能である。また、本実施形態では、充電アダプタにスピーカ２１６を内蔵する例を示したが、マイクや録音部等、その他の構成、機能を内蔵していてもよい。マイクを内蔵する場合、収音した音声をＤＡＰに送信し、ＤＡＰを録音機として用いることが可能である。   In addition, the shape of a charging adapter and a charging stand is not restricted to the said example. For example, the charging adapter may be a case-shaped housing that covers the entire DAP. In this embodiment, an example in which the speaker 216 is built in the charging adapter has been shown, but other configurations and functions such as a microphone and a recording unit may be built in. When a microphone is incorporated, the collected sound can be transmitted to the DAP, and the DAP can be used as a recorder.

さらに、本実施形態では、電子機器としてＤＡＰの例を示したが、無論デジタルカメラ等、他の電子機器であっても本発明を適用することが可能である。   Furthermore, in this embodiment, an example of DAP is shown as an electronic device, but it goes without saying that the present invention can be applied to other electronic devices such as a digital camera.
