20140233766 | FLAT-TYPE SPEAKER HAVING A PLURALITY OF CONSECUTIVELY CONNECTED MAGNETIC CIRCUITS - The present invention relates to a flat-type speaker, and more particularly, to a flat-type speaker in which a plurality of magnetic circuits are consecutively connected in series or in parallel so as to constitute one speaker. In the flat-type speaker in which the plurality of magnetic circuits are consecutively connected, two or more voice coil plates, on each of which voice coils are printed, are successively arranged, and two or more vibrating-reed plates in the form of a thin film are arranged on the upper ends of the two or more voice coil plates, respectively, such that said vibrating-reed plates are electrically isolated from each other. Also, said voice coils and said two or more vibrating-reed plates are electrically connected together. | 08-21-2014 |
20140219494 | FLAT TYPE SPEAKER COMBINING N MAGNET AND N+1 VOICE COIL PLATE - The present invention relates to a flat-type speaker, and more particularly, to a flat-type speaker having one magnet for transferring vibration into a diaphragm and two voice coil plates in one magnetic circuit, wherein the voice coil plates are coupled to both sides of the magnet. The flat-type speaker in which n magnets and n+1 voice coil plates are coupled to each other consists essentially of: the magnet positioned on a central portion; a pair of yoke plates having magnetic bodies spaced a predetermined distance apart from the magnet, such that the magnet is between the yoke plates; two voice coil plates having voice coils inserted between the magnet and one of the yoke plates and between the magnet and the other yoke plate; and a diaphragm vibrated by receiving the vibration of the voice coil plates in a state where the diaphragm contacts upper ends of the voice coil plates. | 08-07-2014 |
20140161303 | FLAT-TYPE SPEAKER HAVING PLURALITY OF MAGNETIC CIRCUITS WHICH ARE HORIZONTALLY CONNECTED - The present invention relates to a flat-type speaker, and more specifically, to a flat-type speaker in which a plurality of magnetic circuits are horizontally connected in serial or in parallel such that one speaker is formed. According to the present invention, a flat-type speaker in which a plurality of magnetic circuits are horizontally connected is constituted by: a horizontal connection structure in which two or more pairs of independent magnetic bodies having different polarities are equipped; on said two or more magnetic bodies, enabling two or more voice coil plates, on which voice coils are printed, to be vertically arranged between the respective magnetic bodies in a horizontal direction; enabling the stream of currents of said two or more voice coil plates to maintain the same direction; allowing two or more thin film-shaped vibration-lead plates to be positioned on the upper end of said two or more voice coil plates such that the plates are electrically separated from each other; and allowing said voice coils and said two or more vibration-lead plates to be electrically connected with each other. | 06-12-2014 |
20140044287 | FLAT TYPE SPEAKER HAVING DAMPER-LEAD PLATE OF PCB VOICE COIL PLATE - The present invention relates to a flat type speaker, and more particularly, to a flat type speaker having a damper-lead plate of a PCB voice coil plate, which improves the quality deterioration due to the reduction of production process and the disconnection of a lead wire, by being attached to the top of a voice coil plate, increases vibration efficiency, and eliminates the lead wire connection of the voice coil. The flat type speaker having a damper-lead plate of a PCB voice coil plate according to the present invention comprises: a pair of magnetic bodies having a magnet and a yoke formed side by side, separated at a predetermined interval; a voice coil plate inserted in the space between the magnetic bodies, and having formed thereon a voice coil with a spiral pattern printed thereon; a damper-lead plate having a first damper-lead plate and a second damper-lead plate, which are physically separated, each having +, − terminals formed on the front ends thereof, wherein the first and the second damper-lead plates are each equipped with a coil plate spline, which adheres to the upper end of the voice coil plate, and at least one wing spline having one end thereof connected to the coil plate spline and the other end connected to the + or − terminals; and a vibration plate, which vibrates from the vibration received from the voice coil plate, while being contacted to the upper end portion of the damper-lead plate. | 02-13-2014 |
20140037114 | FLAT TYPE SPEAKER HAVING VIBRATION-LEAD PLATE ATTACHED ON TOP OF VIBRATION PLATE - The present invention relates to a flat type speaker, and more particularly, to a flat type speaker of a vibration-lead plate of a voice coil plate, improving the quality deterioration due to the reduction of production process and the disconnection of a lead wire, by being attached to the top of a voice coil plate, increasing vibration efficiency, and eliminating the lead wire connection of the voice coil. The flat type speaker of a vibration-lead plate of a voice coil plate according to the present invention comprises: a pair of magnetic bodies having a magnet and a yoke formed side by side, separated at a predetermined interval; a voice coil plate inserted in the space between the magnetic bodies, and having formed thereon a voice coil with a spiral pattern printed thereon; a vibration-lead plate having a first vibration-lead plate and a second vibration-lead plate, which are physically separated, each having +, − terminals formed on the front ends thereof, wherein the first and the second vibration-lead plates are each equipped with a coil plate spline, which adheres to the upper end of the voice coil plate, and at least one wing spline having one end thereof connected to the coil plate spline and the other end connected to the + or − terminals; and a vibration plate, which vibrates from the vibration received from the voice coil plate, while being contacted to the upper end portion of the vibration-lead plate. | 02-06-2014 |
20130161122 | VIBRATION-LEAD PLATE FOR FLAT TYPE SPEAKER, MOUNTED BETWEEN VOICE COIL PLATE AND VIBRATION PLATE - A vibration-lead plate for a flat speaker is mounted between a voice coil plate and a vibration plate for increasing vibrational efficiency and removing the lead wire of a voice coil. The vibration-lead plate includes: a coil plate-spline, mounted between a voice coil plate having a voice coil formed in the shape of a spiral track and a vibration plate to vibrate according to the movement of the voice coil plate for generating sound, and formed in the center so as to be adhered to the voice coil plate; an edge-spline, connected to one side of the coil plate-spline and the edge of the vibration plate so as to variably correspond to vibrations; and a vibration plate outside portion, connected to one side of the edge-spline and adhered to the outside portion of the edge of the vibration plate. | 06-27-2013 |
20130089232 | VOICE FILM OF MULTI-LAYERED STRUCTURE FOR FLAT TYPE SPEAKER - The present invention relates to a voice film having a multi-layered structure for a flat panel speaker, including a PCB configured to have permanent magnets disposed on the left and right sides thereof, to have a voice coil patterned therein and disposed between the permanent magnets on the left and right sides so that the voice coil is vibrated up and down, and to have a PCB structure of a stack structure and coil patterns formed on surfaces of the highest PCB, one or more intermediate layer PCBs, and the lowest PCB in the form of a consecutive spiral track, wherein the start points of coil patterns of adjacent PCBs formed in layers, from among the coil patterns, are shorted through a via hole and are bonded to the respective end points of the coil patterns of the adjacent PCBs at the end points of the coil patterns. | 04-11-2013 |
