〔産業上の利用分野〕
本発明け、携帯用音響機器の音量調整手段の改良に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an improvement in volume adjustment means for portable audio equipment.
従来の携帯用音響機器祉、周囲の騒音にかかわらず音量
は一定である。With conventional portable audio equipment, the volume remains constant regardless of surrounding noise.
このため利用者は、音量を周囲の騒音の状況によルその
つと調整しなければならないという不便さがあった。ま
た、−変音量を大きくすると、周囲が静かであることに
気が付かずに周囲の人間に迷惑をかけてしまうという欠
点があった。Therefore, the user has the inconvenience of having to adjust the volume depending on the surrounding noise situation. Furthermore, if the -variable volume is increased, the user may not notice that the surrounding area is quiet and may disturb other people.
本発明の目的は、音量調整を自動化することにより、利
用者の音量調整のわずられしさをなくし、常に快適に利
用できる携帯用音響機器を提供するものである。An object of the present invention is to provide a portable audio device that can be used comfortably at all times by automating the volume adjustment so that the user does not have to worry about adjusting the volume.
本発明によれば、本体に、外部の騒音を検知する手段を
取）付けて、それにより音量を自動的に調整する携帯川
音４１ｉｌＩａ器を得る。According to the present invention, a portable Kawaon 41ilIa device is provided in which a means for detecting external noise is attached to the main body, thereby automatically adjusting the volume.
次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.
第１図は本発明の一実施例のブロック図であり、１は外
音センサ、２は音量調整器、３は増幅器。FIG. 1 is a block diagram of an embodiment of the present invention, in which 1 is an external sound sensor, 2 is a volume adjuster, and 3 is an amplifier.
４はヘッドホーン、５＃′ｉカセツト・デツキ部（音響
機器）である。4 is a headphone, and 5#'i is a cassette deck section (acoustic equipment).
音量調整器２は外音センサ１により、外音を検知しその
値が以前の値よシ太きければ増幅器３によりヘッドホー
ン４の出力を犬きくする。また、外音が以前の値よりも
ｌＪＸさければ出力を小さくするように働らく。この外
音センサ１には人間の聴感特性に合わせた沖波器を備え
ておくと、音量調節が大変自然に感じる。The volume adjuster 2 uses an external sound sensor 1 to detect an external sound, and if the value is greater than the previous value, the amplifier 3 increases the output of the headphones 4. Also, if the external sound is lJX lower than the previous value, it works to reduce the output. If this external sound sensor 1 is equipped with an oscillator that matches the human hearing characteristics, volume adjustment will feel very natural.
本発明によれば、利用者は周囲の騒音にかかわらす常に
快適な音量で携帯川音Ｗ機器を利用することができる。According to the present invention, the user can always use the portable Kawaon W device at a comfortable volume regardless of surrounding noise.
