Description
Die Erfindung betrifft einen Lautsprecher mit einem Magneten, einem in diesem axial beweglichen Spulenträger und einer mit dem Spulenträger verbundenen, wenigstens im wesentlichen konusförmigen ersten Membran.The The invention relates to a loudspeaker with a magnet, a in this axially movable coil carrier and one connected to the coil carrier, at least substantially cone-shaped first membrane.
Derartige sogenannte elektrodynamische Lautsprecher sind seit Langem in verschiedener Ausgestaltung bekannt. Bei Beaufschlagung der von dem Spulenträger getragenen Spule bewegt sich dieser und veranlasst die sich konisch erweiternde Membran zu einer entsprechenden Bewegung, wodurch in einen Raum abgegebener Schall erzeugt wird.such so-called electrodynamic speakers have long been in different Design known. Upon application of the carried by the bobbin Coil moves this and causes the flared diaphragm to a corresponding movement, which is discharged into a room Sound is generated.
Bei derartigen Lautsprechern ist die Glättung und Verbreiterung des Frequenzganges von erheblicher Bedeutung. Diese Glättung und Verbreiterung des Frequenzganges soll durch die Erfindung weiter verbessert werden.at such speakers is the smoothing and broadening of the Frequency response of considerable importance. This smoothing and Broadening of the frequency response is to be further improved by the invention become.
Erfindungsgemäß wird diese Aufgabe gelöst durch eine von der ersten Membran aufgenommene zweite Membran, die wenigstens im Wesentlichen kugelabschnittsförmig ist, mit der Stirnfläche des Spulenträgers verbunden ist, im Bereich ihres feinen Umfangsrings mit der ersten Membran verbunden ist, und zwischen ihrer Verbindung mit dem Spulenträger und dem Bereich des freien Umfangsrings über eine Stützverbindung mit der ersten Membran verbunden ist.According to the invention this Task solved by a received by the first membrane second membrane, at least essentially spherical segment-shaped is, with the face of the bobbin is connected, in the region of its fine peripheral ring with the first Membrane is connected, and between its connection to the coil carrier and the region of the free peripheral ring via a support connection with the first Membrane is connected.
Die Steifigkeit der zweiten Membran wird bei einer Ausbildung mit einer dieser kristallartigen Struktur gebenden Prägungen verbessert.The Stiffness of the second membrane is in a training with a this embossment giving this crystal-like structure improved.
Eine bevorzugte Ausführungsform zeichnet sich dadurch aus, dass die beiden Membranen aus unterschiedlichen Werkstoffen gebildet sind, wobei die erste Membran vorzugsweise aus Papier oder Pappe und die zweite Membran aus einer Metallfolie gefertigt ist.A preferred embodiment is characterized by the fact that the two membranes of different Materials are formed, wherein the first membrane is preferably made of paper or cardboard and the second membrane made of a metal foil is.
Die Erfindung wird im Folgenden anhand einer Zeichnung erläutert. Dabei zeigt:The Invention will be explained below with reference to a drawing. there shows:
