Description

Sprechmaschine. Gegenstand der Erfindung ist eine Sprechmaschine, bei der die schallerzeugenden und schallübertragenden Teile mit alleiniger Ausnahme des Schallstiftes, des Schallhebels und seines Lagers aus nichtmetallischen Stoffen bestehen. Diesem Bekannten gegenüber beruht die Neuerung gemäß der Erfindung darin, daß das Schalldosengehäuse, die Membran, der Tonarm, das Verbindungsstück und der Schalltrichter, also alle diese Teile gleichzeitig aus Celluloseestern bestehen. Es hat sich gezeigt, daß hierdurch die unerwünschten Klirr- und Kratzgeräusche, die bei bekannten Sprechmaschinen auftreten, stark unterdrückt werden und ein voller, wohlklingender Ton bei der Wiedergabe erzielt wird.Talking machine. The subject of the invention is a speaking machine, in the case of the sound-generating and sound-transmitting parts with the sole exception the sound pen, the sound lever and its bearing made of non-metallic materials exist. In relation to this acquaintance, the innovation according to the invention is based on that the sound box, the diaphragm, the tonearm, the connector and the Bell, so all these parts consist of cellulose esters at the same time. It has been shown that this causes the undesirable clanking and scratching noises, which occur in known speaking machines, are strongly suppressed and a full, good-sounding sound is achieved during playback.

Es ist schon vielfach versucht worden, die unerwünschten Klirr- und Kratzgeräusche dadurch zu vermeiden, daß Einzelteile von Sprechmaschinen aus nichtmetallischen Stoffen hergestellt worden sind. So hat man beispielsweise versucht, den Schalltrichter oder die Membran oder die Schalldose oder den Tonarm aus. nichtmetallischen Stoffen, wie Holz, Gelluloid, Cellulo.seester, Glas u. dgl. zu erzeugen; auch Gummi, Papiermache und Gelatineleim sind für diesen Zweck bereits versucht worden. Es sind auch Sprechmaschinen bekannt, bei denen die Schalldose, der Schalltrichter und der Tonarm aus Holz bestehen, aber eine Glimmermembran verwandt ist. Es genügt aber nicht, wenn nur der eine oder andere oder auch mehrere Einzelteile, wie der Tonarm und der Schalltrichter oder der Schalldosenkörper, aus nichtmetallischen Stoffen hergestellt werden. Erst wenn alle diese Teile ausnahmslos aus Ce11u-1o;seestern bestehen. und nur für den Schallstift, seinen Hebel und dessen Lager z. B. Metall verwendet ist, wird, wie Versuche ergeben haben, gemäß der Erfindung der gewünschte Erfolg erreicht.Many attempts have been made to eliminate the undesirable distortion and Avoid scratching noises by making individual parts of speaking machines made of non-metallic Fabrics have been manufactured. For example, attempts have been made to use the bell or the membrane or the sound box or the tonearm. non-metallic substances, such as wood, gelluloid, cellulosic ester, glass and the like; also rubber, paper mache and gelatin glue have been tried for this purpose. They are also talking machines known, in which the sound box, the bell and the tonearm are made of wood, but a mica membrane is related. But it is not enough if only one or other or several individual parts, such as the tonearm and the bell or the silencer body, are made of non-metallic materials. Only when all of these parts consist without exception of Ce11u-1o; starfish. and only for the sound pen, its lever and its camp z. B. Metal is used, as experiments show have achieved the desired success according to the invention.
