【発明の詳細な説明】
本発明はヘッドホンで聞く携帯式受信機に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a portable receiver for listening through headphones.
最近、歩きながらラジオ放送を聞く携帯式受信機やカセ
ットテープを再生して聞く携帯式カセットが商品として
出まわっている。このような商品ではヘッドホン専用で
聞くものが多い。Recently, products such as portable receivers for listening to radio broadcasts while walking and portable cassettes for playing cassette tapes have become available. Many of these products are designed exclusively for listening with headphones.
ところで、従来のこの種の受信機では音量ボリュームが
かなり大の位置にセットされている状態でヘッドホンを
耳に装着しながら電源スィッチをONすると、同特に強
烈な音が耳に飛び込み不快を感じることがある。このよ
うなことは−間約な衝撃だけでなく輝聴の言回にもなり
得る。By the way, with conventional receivers of this type, if you turn on the power switch while wearing headphones with the volume set to a very high position, the same particularly strong sound will reach your ears and cause discomfort. There is. This kind of thing can be not only a temporary shock, but also a brilliant statement.
本発明はこのような欠点を解決したもので、電源スイツ
チON直後に音量ボリューム設定の音量が即時に出力さ
れず、その音量に徐々に立上る機能を持つことを特徴と
している。The present invention solves these drawbacks, and is characterized by having a function in which the volume setting volume is not immediately outputted immediately after the power switch is turned on, but gradually increases to that volume.
第1図は本発明の実施回路例であり、ブロック図的に示

ィッチ9をONした直後に電源ON検出回路10が動作
し、その信号で音量制御回路12が作動し、小さい音量
から徐々に大きくなり数秒程度で音量ボリューム12の
設定値に至る。この音量と時間の関係を第2図に示した
。上記動作を電源スイツチ9をONする毎に繰り返す。FIG. 1 shows an example of a circuit for implementing the present invention, which is shown in a block diagram. In the figure, numerals 1 to 6 are general circuit configurations of a receiver ranging from an antenna to a low frequency amplification circuit. Headphones 7 are connected to the low frequency amplification circuit B. Immediately after the power switch 9 is turned on, the power ON detection circuit 10 is activated, and the volume control circuit 12 is activated in response to the signal, and the volume gradually increases from a low volume until it reaches the set value of the volume volume 12 in about a few seconds. The relationship between volume and time is shown in Figure 2. The above operation is repeated every time the power switch 9 is turned on.
このような機能を持つ本発明の受信機ではヘッドホンを
装着した状態で電源スィッチをONしても徐々に音量が
増大していくので、その間にボリュームの大きいことに
気がついたり、急激なショックからのがれられるので不
快感や健康上大きな効果を持つ。With the receiver of the present invention, which has such a function, even if you turn on the power switch while wearing headphones, the volume will gradually increase, so you may notice that the volume is high during that time, or you may be worried about sudden shocks. Since it can be removed, it causes discomfort and has great health benefits.
