Schallpegelmeßgerät, eingebaut in CD- HülleSound level meter built into CD case
Es ist bekannt, daß CD- Hüllen aus durchsichtigem klären oder farbigen Kunststoff hergestellt werden. Es ist weiterhin bekannt, daß immer mehr CD- Hüllen bewegliche, mechanische Teile enthalten, die zum Kauf anreizen sollen, einfach dekorativen Zwecken dient oder die auf der zur CD- Hülle dazugehörigen CD entsprechende Musik optisch unterstützt. Bei Benutzung der CD bleibt die Hülle meistens unbeachtet. Die heutige Musik wird jedoch auch je nach Art {Rock-, Pop- und besonders Technomusik) extrem laut gehört. Gehörprobleme sind diesbezüglich oft der Fail.It is known that CD cases are made of transparent or colored plastic. It is also known that more and more CD cases contain moving, mechanical parts that are intended to encourage purchase, are simply decorative or visually support the music on the CD that comes with the case. When the CD is in use, the case is usually ignored. However, today's music is also listened to extremely loudly, depending on the type (rock, pop and especially techno music). Hearing problems are often the cause of this.
Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, eine CD-Hüile zu schaffen, die anstelle einer einfachen Schutzfunktion auch eine elektronische optisch- technische, insbesonders vor zu hoher Lautstärke warnende Funktion übernimmt.The invention specified in claim 1 is based on the problem of creating a CD case which, instead of a simple protective function, also performs an electronic optical-technical function, in particular warning against excessive volume.
Diese Problem wird mit den in Schutzanspruch 1 aufgeführten Merkmalen gelöst.This problem is solved with the features listed in claim 1.
Mit der Erfindung wird erreicht, daß bei optischem Sichtkontakt zwischen Erfindung und Musikhörer dieser, ebenfalls optisch, durch die Leuchtdioden, je nach Anzahl der aufleuchtenden Leuchtdioden, vor einem zu hohem Lautstärkepegel gewarnt wird.The invention achieves that when there is visual contact between the invention and the music listener, the latter is also visually warned by the LEDs, depending on the number of LEDs that light up, of an excessively high volume level.
Eine vorteilhafte Ausgestaltung der Erfindung ist in Schutzanspruch 2 angegeben.
Ein Ausführungsbeispiei der Erfindung wird anhand der Figuren A und B erläutert.An advantageous embodiment of the invention is specified in claim 2.
An embodiment of the invention is explained with reference to Figures A and B.

FIGUR B CD- Hülle mit eingebauter elektronischer SchaltungFIGURE B CD case with built-in electronic circuit
Über das Mikrofon (1) werden Schallwellen aus der Umgebung aufgenommen. Diese Schallwellen werden in elektrische Impulse umgewandelt und der elektronischen Verstärkerstufe (2) zugeführt. Eine anschließende elektronische Treiberschaltung (3) läßt dann je nach vorhandener Schalistärke am Mikrofon (1) mehr oder weniger Leuchtdioden (4) aufleuchten. Zweckmäßigerweise sollte die Leuchtdiodenkette (4) (d. h. Anzahl der Leuchtdioden) mindestens drei Leuchtdioden umfassen. Das gesamte elektronische System (5) wird über den Schalter (6) ein- bzw. ausgeschaltet, über die Knopfbatterien (7) versorgt und kann in den derzeitigen Standart- CD- Hüllen eingesetzt werden. Figur B zeigt die CD- Hülle (8) mit der eingebauten Elektronik aus der Draufsicht und (9) zeigt die Seitenansicht.Sound waves from the environment are picked up via the microphone (1). These sound waves are converted into electrical impulses and fed to the electronic amplifier stage (2). A subsequent electronic driver circuit (3) then lights up more or fewer LEDs (4) depending on the sound intensity at the microphone (1). Ideally, the LED chain (4) (i.e. number of LEDs) should include at least three LEDs. The entire electronic system (5) is switched on and off via the switch (6), is powered by the button batteries (7) and can be used in the current standard CD cases. Figure B shows the CD case (8) with the built-in electronics from above and (9) shows the side view.
