Flat type speaker having vibration-lead plate attached on top of vibration plate

Abstract

A flat-type speaker includes a voice coil plate, a pair of magnetic bodies having a magnet and a yoke formed side by side, separated at a predetermined interval; the voice coil plate being in a space between the magnetic bodies, and having printed thereon a voice coil with a spiral pattern; a vibration-lead plate having physically separated first and second vibration-lead plates, each having +, − terminals formed on the front ends thereof, the first and the second vibration-lead plates 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 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.

The invention claimed is: 
     
       1. A flat type speaker having damper-lead plates mounted on a vibration plate, comprising:
 a pair of magnetic bodies spaced apart from each other at a specific interval, formed side by side, and each having a magnet and yoke formed therein; 
 a voice coil plate inserted into an interval between the magnetic bodies and having a voice coil spirally patterned and printed formed therein; 
 a vibration plate brought in contact with a top of the voice coil plate and vibrated in response to a vibration of the voice coil plate; and 
 first and second damper-lead plates adhered to a top of a main body of the vibration plate and arranged in parallel, each of the first and second damper-lead plates comprising a vibration plate spline having a slim and long plate form, and one or more wing splines having one end connected to the vibration plate spline and having a slim and long plate form. 
 
     
     
       2. The flat type speaker of  claim 1 , wherein:
 a lead block having a ‘ ’ form is formed at one end of the vibration plate spline, 
 the lead blocks are configured to penetrate vibration plate holes formed in the vibration plate and connected to the voice coil by soldering, and 
 a + or − terminal is formed at one end of the wing spline. 
 
     
     
       3. The flat type speaker of  claim 1 , wherein:
 a pair of the wing splines are extended from the vibration plate spline and bent in opposite directions, and 
 a + or − terminal is formed at a front end of each of the pair of the wing splines. 
 
     
     
       4. The flat type speaker of  claim 1 , wherein the wing spline is placed on an edge of the vibration plate. 
     
     
       5. The flat type speaker of  claim 1 , wherein:
 the first and the second damper-lead plates are made of conductive and metallic materials, and 
 the second damper-lead plate has a symmetrical structure rotated by 180 degrees from the first damper-lead plate. 
 
     
     
       6. The flat type speaker of  claim 1 , wherein:
 the first and the second damper-lead plates are made of insulating materials and formed of one body, and 
 the first and the second damper-lead plates are coated with conductive materials in such a way as to be electrically separated.
