| titleOfInvention | Condenser type speaker |
| abstract | The disclosed condenser speaker is coated with an electrode forming conductor on one surface of a polymer film to form a conductor coating layer, and an aerogel is coated on the other surface of the polymer film to form an airgel layer, and a spaced distance from the diaphragm. An insulator formed at a central portion of a bipolar plate forming an anode together with a diaphragm, a PCB electrically connected to the diaphragm and the bipolar plate to apply an external AC voltage, and a receiving hole in which the diaphragm and the bipolar plate are accommodated. And it includes a case for receiving and fixing each of the above components and a negative pressure outlet formed on one surface.n n n According to the present invention described above, by using a single diaphragm structurally simplifying the low range by the damping effect of the diaphragm in which the airgel layer is formed, it is possible to improve the sound quality of the low frequency band. |
