Description

【0001】
【発明の属する技術分野】
本発明は、電池残量通知装置及び通知方法に係り、特に電池で駆動する携帯型音声再生装置において、電池残量の検出結果が所定の値以下になった際、再生音声の音量や音律を変化させる、あるいは再生音声に電池残量を通知する音声を割り込ませる装置及び方法に関するものである。
【0002】
【従来の技術】
従来、携帯型のコンパクトカセットプレーヤなど電池で駆動するアナログ音声再生装置では、磁気テープに記録された音声データを、内部のモータを回転させ、記録メディアを動かすことにより読み取っていたので、電池の残量が減ってくると電流、電圧などが下がり、その結果モータの回転数が下がる等の要因で音声の再生速度が遅くなることがあった。そこで、最後まで同じ速度(以下テンポと記す)や音律(以下ピッチと記す)で音声を再生することが目標とされ現在では、最後までモータの回転数を落とさない技術や、デジタル化された音声データを内蔵のバッファメモリに先取りして読み込んでおく技術等の進歩で、最後まで音声のテンポやピッチを変えずに再生ができるようになった。
【0003】
また、スマートメディア(登録商標)等に代表されるメモリカードや内蔵メモリなど駆動力の要らない記録媒体に記録した音声データの再生装置では、モータなどの駆動部が不要なので、最後まで音声のテンポやピッチを変えずに再生ができるようになっている。
従って、ユーザが音声や音楽を聞いている際、電池の残量がなくなると突然再生が終わってしまうという問題があった。
【0004】
そこで、ユーザが電池すなわち再生時間の残量を知るために、携帯型音声再生装置あるいはリモコン装置に液晶画面などの表示部を設け、その色や明るさを変えたり、電池残量が減るにつれて残量目盛りの表示を切り替えていったり、警告表示で示すなど、何らかの方法で電池残量を表示部に表示することが行われている(例えば、特許文献1参照。)。
【0005】

特開2002−32980公報(第2−4頁、第3−6図)
【0006】
【発明が解決しようとする課題】
ところで、このような携帯型音声再生装置を用いて、ユーザが音声や音楽を聞く場合、衣服のポケットあるいはバッグの中に携帯型音声再生装置を置き、音声ケーブルを介しヘッドフォンで聞くという形態をとり、常に表示部を見ているわけではない。リモコン装置も同様に、衣服のポケットあるいは襟等に挟み込みそこからさらに音声ケーブルを介しヘッドフォンで聞くという形態をとり、やはり常に表示部を見ているわけではない。
【0007】
従って、ユーザが電池残量を知る方法は表示部を見る以外になく、ユーザが電池残量を知りたい、後でまた音声を再生したいから再生時間すなわち電池残量を残しておきたいなどの理由で電池残量を気にする場合、いちいち携帯型音声再生装置を取り出し表示部を見て確認するか、リモコン装置の表示部を見て確認しなければならないことが問題であった。
【0008】
本発明は、以上の点に鑑みなされたもので、電池で駆動する携帯型音声再生装置において音楽データの再生中、電池残量の検出結果が所定の値以下になった際、再生音声のテンポ、ピッチ、音量を変化させたり、再生音声中に電池残量を知らせる情報を再生音声に割り込ませたりすることで、その表示部の残量表示をいちいち見なくても、電池残量を知らせることができる電池残量通知装置を提供する。
【0009】
【課題を解決するための手段】
本発明は、上記課題を解決するために、以下に記載の手段よりなる。
すなわち、
電池で駆動する携帯型音声再生装置において、
電池残量を検出する電池制御部と、
前記検出した電池残量に応じて再生音声の速度や音律、音量を制御し、または再生音声以外の通知音声を割り込ませ、前記電池残量を通知するための再生音声調整部と、
を有することを特徴とする携帯型音声再生装置の電池残量通知装置。
【0010】
【発明の実施の形態】
以下、本発明の電池残量通知装置の発明の実施の形態につき、好ましい実施例により説明する。
図1は、本実施例に適用される携帯型音声再生装置10の概略ブロック図である。携帯型音声再生装置10は、ユーザが音声データの再生や停止、早送り、巻戻しをしたり、複数の音声データがある場合の再生順をプログラムしたり、出力音声の音量調整をするなどの各種操作を行う操作部101、現在再生している音声データの情報や、音量、電池残量などを表示する表示部102、音声再生や再生装置10の各部の電源となる電池を備えた電池部103、前記電池部の電池残量を検出したり、その他電池に関する制御をしたりする電池制御部104、再生装置10全体を制御する装置制御部105、音声データの記録させた内蔵メモリまたはCD、MD、DVDやメモリカードなどの外部記憶メディアである音声データ記憶部106、前記音声データ記憶部106から音声データを読み取る音声データ読み取り部107、前記音声データを一時的に記憶するバッファメモリ108、前記音声データをD/A変換するD/A変換部109、再生する音声データのテンポやピッチ、音量などを変更する再生音声調整部110、音声を出力するスピーカやヘッドホン、イヤホンなどの音声出力部111を備えている。
【0011】
次に、上記構成による携帯型音声再生装置10の動作につき図2のフローチャートを用いて詳細に説明する。
携帯型音声再生装置10で音声データを再生する場合(S101でYes)、操作部101から装置制御部105に再生命令を送る。再生しない場合(S101でNo)は終了する。再生する場合、装置制御部105は電池部103からの電力を元に起動し、装置制御部105から音声データ読み取り部107に、音声データ記憶部106から音声データを読み取るよう命令を送る。音声データ記憶部106から読み取られた音声データはバッファメモリ108に一旦記憶する。同時に、またはこの前後に装置制御部105は電池制御部104に電池部103の電池の残量を検出するよう命令を送り、電池制御部104は電池部103の電圧や電流、温度、その他電池に関して得られる情報を元に電池残量を調べる。
【0012】
電池残量が十分ある場合(S102で「十分」)、バッファメモリ108からD/A変換部109へ前記音声データを送り、D/A変換後、元の音声データをそのまま通常通り再生し、音声出力部111から出力する(S103)。
【0013】
電池残量が所定容量以下であれば(S102で「所定容量以下」)、バッファメモリ108からD/A変換部109音声データを送り、D/A変換後に再生音声調整部110で音声のピッチやテンポ、音量を変更した後、もしくは再生音声調整部110で音声のピッチやテンポ、音量を変更した後にD/A変換し、変更後の音声データを音声出力部111から出力する。
【0014】
この時、表示部102が電池残量を表示する機能を持っていれば電池残量を表示する(S105)。そして、操作部101から装置制御部105に再生停止命令が来なければこのまま再生を続行し(S107)、再びS102に戻り同じステップを繰り返す。操作部101から再生停止命令が送られてきたら(S106でNo)音声の出力及び音声の読み込みを停止し、再生を終了する(S108)。
【0015】
ここで予め、電池残量が不足してきた時の通知の有無や、電池残量(再生時間の残り)がどの程度になったら通知するか、複数の通知方法がある場合はどの方法で通知するかを操作部101で操作して装置制御部105で設定しておくことができるようにすれば、必要な時だけ電池残量の通知をするようにできる。
【0016】
ここで複数の通知方法とは、音声のテンポを遅くまたは早く変更する、ピッチを高くまたは低く変更する、音量を小さくするなどのことである。そして、ユーザが音声を聞いていて気が付くような音声の変化であればこれ以外であっても良い。また、通知は電池残量が所定容量以下になった場合ずっと行い続けてもよいが、通知後、一定時間だけまたは操作部101から通知停止命令が来るまでにしてもよい。
【0017】
また、再生音声調整部110において、元の音声データを変化させる際(S104)、再生する音声データのテンポやピッチ、音量などを変えるのではなく、例えば通知音として「ピッピッ」という電子音や、「電池残量が少なくなりました」と言う人の声などの別の音声を合成し、元の音声データと一緒に音声出力部111から出力する。これにより、音声データの再生中に別の音声の割り込みは入るが、元の音声データのピッチやテンポや音量を変えることなく、電池残量が少なくなったことが通知可能になる。
【0018】
さらに、通知音を入れる場合に、再生音声の音声データの音量を小さくし通知音を割り込ませるよう両方を組合わせて構成して、よりユーザがわかりやすくするようにしてもよい。
【0019】
【発明の効果】
本発明は、ユーザが電池で駆動する携帯型音声再生装置において音楽や音声データの再生中、電池残量の検出を行いその結果に応じ、再生速度、音律、音量を変化させたり、再生音声中に再生音声とは別の電池残量の通知を知らせる音声情報を割り込ませたりすることで、携帯型音声再生装置の表示部の残量表示をいちいち見なくても、電池残量を知ることができ、利便性が向上するという効果がある。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a battery remaining amount notification device and a notification method, and in particular, in a portable audio playback device driven by a battery, when the detection result of the battery remaining amount becomes a predetermined value or less, the volume and tone of the playback sound are adjusted. The present invention relates to a device and a method for changing the sound or interrupting the sound for notifying the remaining battery level in the reproduced sound.
[0002]
[Prior art]
Conventionally, in a battery-driven analog audio reproducing device such as a portable compact cassette player, audio data recorded on a magnetic tape is read by rotating an internal motor and moving a recording medium. When the amount decreases, the current, voltage and the like decrease, and as a result, the speed of sound reproduction may decrease due to factors such as a decrease in the number of revolutions of the motor. Therefore, the goal is to reproduce the sound at the same speed (hereinafter referred to as tempo) or tonality (hereinafter referred to as pitch) until the end. At present, the technology that does not reduce the rotation speed of the motor until the end, the digitized sound Advances in technologies such as pre-reading data into the built-in buffer memory and reading data have made it possible to reproduce audio without changing the tempo or pitch until the end.
[0003]
Also, in a playback device for audio data recorded on a recording medium that does not require a driving force, such as a memory card typified by SmartMedia (registered trademark) or a built-in memory, a drive unit such as a motor is not required, so that the audio tempo is not completed. It can be played without changing the pitch or pitch.
Therefore, when the user is listening to voice or music, there is a problem that the reproduction is suddenly terminated when the remaining battery power is exhausted.
[0004]
Therefore, in order to allow the user to know the remaining amount of the battery, that is, the remaining amount of the playback time, a display unit such as a liquid crystal screen is provided in the portable audio playback device or the remote control device, and the color or brightness is changed or the remaining amount decreases as the remaining battery amount decreases. The display of the remaining battery level on the display unit has been performed by some method, such as switching the display of the amount scale or displaying a warning (for example, see Patent Document 1).

[Problems to be solved by the invention]
By the way, when a user listens to voice or music using such a portable audio reproducing apparatus, the user puts the portable audio reproducing apparatus in a pocket or a bag of clothes and listens to it with headphones via an audio cable. However, the user does not always look at the display unit. Similarly, the remote control device takes a form of being inserted into a pocket or a collar of clothes, and then listening through headphones through an audio cable, and does not always look at the display unit.
[0007]
Therefore, there is no other way for the user to know the remaining battery level than to look at the display unit. However, when the user is concerned about the remaining battery power, the user must take out the portable audio playback device and check the display unit or check the display unit of the remote control device.
[0008]
SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and when a battery-powered portable audio reproducing apparatus is playing music data, when the detection result of the remaining battery level falls below a predetermined value, the tempo of the reproduced audio is reduced.

[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention for a battery remaining amount notification device of the present invention will be described with reference to preferred examples.
FIG. 1 is a schematic block diagram of a portable audio reproduction device 10 applied to the present embodiment. The portable audio reproduction device 10 is used for various types of operations such as a user's reproduction, stop, fast forward, and rewind of audio data, programming of a reproduction order when there are a plurality of audio data, and volume adjustment of output audio. An operation unit 101 for performing an operation, a display unit 102 for displaying information of audio data currently being reproduced, a volume, a remaining battery level, and the like, and a battery unit 103 including a battery serving as a power supply for each unit of the audio reproduction and reproduction device 10 A battery control unit 104 for detecting the remaining battery level of the battery unit and controlling other batteries; a device control unit 105 for controlling the entire playback device 10; a built-in memory or a CD or MD for recording audio data; Data storage unit 106 which is an external storage medium such as a DVD or a memory card, and a voice data reading unit 107 which reads voice data from the voice data storage unit 106 A buffer memory 108 for temporarily storing the audio data, a D / A converter 109 for D / A converting the audio data, a reproduction audio adjustment unit 110 for changing the tempo, pitch, volume and the like of the audio data to be reproduced; Is provided with an audio output unit 111 such as a speaker, a headphone, or an earphone for outputting the sound.
[0011]
Next, the operation of the portable audio reproduction device 10 having the above configuration will be described in detail with reference to the flowchart of FIG.
When audio data is reproduced by the portable audio reproduction device 10 (Yes in S101), a reproduction command is sent from the operation unit 101 to the device control unit 105. When the reproduction is not performed (No in S101), the process ends. When reproducing, the device control unit 105 starts up based on the power from the battery unit 103 and sends a command to the audio data reading unit 107 to read the audio data from the audio data storage unit 106 from the device control unit 105. The audio data read from the audio data storage unit 106 is temporarily stored in the buffer memory 108. At the same time, or before and after this, the device control unit 105 sends a command to the battery control unit 104 to detect the remaining amount of the battery of the battery unit 103, and the battery control unit 104 checks the voltage, current, temperature, Check the remaining battery level based on the information obtained.
[0012]
When the battery level is sufficient ("sufficient" in S102), the audio data is sent from the buffer memory 108 to the D / A conversion unit 109, and after D / A conversion, the original audio data is reproduced as it is, and the audio data is reproduced. Output from the output unit 111 (S103).
[0013]
If the remaining battery level is equal to or less than the predetermined capacity (“less than or equal to the predetermined capacity” in S102), the D / A conversion unit 109 sends audio data from the buffer memory 108, and after the D / A conversion, the reproduction audio adjustment unit 110 uses After changing the tempo and volume, or after changing the pitch, tempo, and volume of the sound by the reproduced sound adjusting unit 110, D / A conversion is performed, and the changed sound data is output from the sound output unit 111.
[0014]
At this time, if the display unit 102 has a function of displaying the remaining battery level, the remaining battery level is displayed (S105). Then, if the reproduction stop command is not sent from the operation unit 101 to the device control unit 105, the reproduction is continued as it is (S107), and the process returns to S102 again to repeat the same steps. When a playback stop command is sent from the operation unit 101 (No in S106), the output of the voice and the reading of the voice are stopped, and the playback is ended (S108).
[0015]
Here, the presence or absence of a notification when the remaining battery power becomes insufficient, the amount of remaining battery (remaining playback time) to be notified, and the notification method when there are a plurality of notification methods are provided. By operating the operation unit 101 and setting the same in the device control unit 105, it is possible to notify the remaining battery level only when necessary.
[0016]
Here, the plurality of notification methods refer to changing the tempo of the sound slower or faster, changing the pitch higher or lower, and decreasing the volume. Any other sound change that the user may notice while listening to the sound may be used. In addition, the notification may be continuously performed when the remaining battery power becomes equal to or less than the predetermined capacity. However, the notification may be performed for a fixed time after the notification or until a notification stop command is received from the operation unit 101.
[0017]
When changing the original audio data (S104), the reproduction audio adjustment unit 110 does not change the tempo, pitch, volume, or the like of the audio data to be reproduced. For example, an electronic sound such as "beep" as a notification sound, Another voice such as a voice of a person saying "the battery level is low" is synthesized and output from the voice output unit 111 together with the original voice data. As a result, an interruption of another sound is input during the reproduction of the audio data, but it is possible to notify that the remaining battery level is low without changing the pitch, tempo, or volume of the original audio data.
[0018]
Further, when a notification sound is input, both may be configured so that the volume of the audio data of the reproduced sound is reduced and the notification sound is interrupted, so that the user can more easily understand.
[0019]
【The invention's effect】
The present invention provides a portable audio reproducing apparatus driven by a battery, which detects the remaining battery level during music or audio data reproduction, changes the reproduction speed, the tone, and the volume according to the result, or reproduces the audio during reproduction. The battery level can be known without having to look at the remaining level on the display of the portable audio playback device by interrupting the voice information that notifies the remaining battery level separately from the playback audio. This has the effect of improving convenience.
