HINTERGRUND DER ERFINDUNGBACKGROUND OF THE INVENTION
1. Gebiet der Erfindung1. Field of the invention
Die vorliegende Erfindung betrifft einen Dünntyp-Lautsprecher und insbesondere einen Dünntyp-Lautsprecher mit einem Dämpfer.The The present invention relates to a thin-type speaker, and more particularly a thin type speaker with a damper.
2. Beschreibung des Stands der Technik2. Description of the stand of the technique
Ein
herkömmlicher,
dynamischer Lautsprecher
Bei
Einspeisung von elektrischem Strom in die Schwingspule
Der vorstehende Entwurf kann jedoch einfach bei Lautsprechern mit großem Maßstab verwendet werden. Bei einem Dünntyp-Lautsprecher, der in einer mobilen elektronischen Vorrichtung verwendet werden soll, kann der begrenzte innere Raum lediglich die Schwingungsmembran und den Elektromagnet-Satz unterbringen und kein Raum für die vorstehend erwähnte Ausrüstung mit dem Dämpfer liegt vor. Deshalb sind herkömmliche Dünntyp-Lautsprecher nicht für eine hohe Leistungsabgabe geeignet.Of the However, the above design is easy to use with large-scale speakers become. For a thin type speaker, used in a mobile electronic device should, the limited internal space can only the vibration membrane and accommodate the electromagnet set and no room for the above mentioned equipment with the damper is available. That's why conventional Slim type speakers not for a high power output suitable.
ZUSAMMENFASSUNG DER ERFINDUNGSUMMARY THE INVENTION
Die primäre Aufgabe der vorliegenden Erfindung ist die Bereitstellung eines Dünntyp-Lautsprechers, der den begrenzten Innenraum nutzt, um einen Dämpfer für eine hohe Leistungsabgabe zu enthalten.The primary Object of the present invention is to provide a Thin type speaker, the The limited interior uses a damper for a high power output to contain.
Zum Lösen dieser Aufgabe der vorliegenden Erfindung umfasst der Dünntyp-Lautsprecher ein Gehäuse mit einer oben offenen Aufnahmekammer, einen Elektromagnetsatz, der in der oben offenen Aufnahmekammer angebracht ist, und eine Schwingungsmembran. Der Elektromagnet-Satz weist auf, ein Joch, einen Magnet, einen Polschuh und eine Schwingspule. Die Schwingungsmembran ist peripher mit der Peripherie der oben offenen Aufnahmekammer verbunden und weist einen Dämpfer an dem Zentrum davon auf. Der Dämpfer weist einen gerippten Querschnitt und ein Zentrumsteil auf, das mit dem Elektromagnetsatz fest verbunden ist. Die Schwingspule des Elektromagnetsatzes ist an einer Seite der Schwingungsmembran, die der oben offenen Aufnahmekammer zugewandt ist, bereitgestellt und mit der Peripherie des Dämpfers verbunden.To the Solve this Object of the present invention, the thin-type speaker includes a housing with an open-topped receiving chamber, a solenoid set, the is mounted in the open-topped receiving chamber, and a vibration membrane. The electromagnet set indicates a yoke, a magnet, a pole piece and a voice coil. The vibrational membrane is peripheral to the periphery of the top connected open receiving chamber and has a damper the center of it. The damper has a ribbed cross-section and a center part which is firmly connected to the electromagnetic set. The voice coil of the Electromagnet set is on one side of the vibration membrane, the the upper open receiving chamber facing, provided and with the periphery of the damper connected.

Weiterhin kann ein erfindungsgemäßer Lautsprecher vom Papierkonus-Serien- (paper cone series) oder allgemein vom Ferrit-Typ sein, der in einer runden, rechteckigen oder ovalen Form hergestellt ist.Farther can a speaker according to the invention from the paper cone series or generally from the ferrite type be made in a round, rectangular or oval shape.
Zur Bereitstellung vieler Auswahlmöglichkeiten für die Leistungsabgabe und zur Erleichterung einer Herstellung können die Schwingungsmembran und der Dämpfer getrennt aus verschiedenen Materialien hergestellt werden und dann fest aneinander befestigt werden. Dieses Herstellungsverfahren erreicht die gleichen vorstehend genannten Wirkungen.to Providing many choices for the Power output and to facilitate production, the Vibration diaphragm and damper be made of different materials separately and then firmly attached to each other. This manufacturing process achieved the same effects mentioned above.
