Abstract

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.

Claims (18)

1. A vibration-lead plate mounted between a voice coil plate for a flat panel type speaker and a vibration plate, wherein:

the vibration-lead plate is mounted between the voice coil plate having a voice coil of a spiral track form formed therein and the vibration plate vibrated in response to a movement of the voice coil plate, thus generating sound,

a plurality of splines is coupled together and formed in the vibration-lead plate, and

a central part of the vibration-lead plate is adhered to a top of the voice coil plate, and in a state in which one or more of an outside and inside of the vibration-lead plate are adhered to the vibration plate and one of the outside and inside of the vibration-lead plate is fixed, the other of the outside and inside of the vibration-lead plate fluctuates in a sheet spring or damper form.

2. A vibration-lead plate mounted between a voice coil plate for a flat panel type speaker and a vibration plate,

wherein the vibration-lead plate is mounted between the voice coil plate having a voice coil of a spiral track form formed therein and the vibration plate vibrated in response to a movement of the voice coil plate, thus generating sound, and

the vibration-lead plate comprises:

a coil plate-spline formed in a central part of the vibration-lead plate and adhered to the voice coil plate,

an edge-spline connected to one side of the coil plate-spline, connected to an edge of the vibration plate, and variably moved in response to vibration of the vibration plate, and

a vibration plate outside-spline connected to one side of the edge-spline and adhered to an outside part of the edge of the vibration plate.

3. The vibration-lead plate according to claim 2 , wherein terminals connected to power supply terminals formed in a base frame that forms an external appearance are formed at both ends of the vibration plate outside-spline.

4. The vibration-lead plate according to claim 2 , wherein:

a pair of the vibration-lead plates are formed and physically separated from each other, and

the other vibration-lead plate is symmetrical to the one vibration-lead plate based on the one vibration-lead plate and rotated 180 degrees.

5. The vibration-lead plate according to claim 4 , wherein terminals connected to power supply terminals formed in a base frame that forms an external appearance are formed at both ends of the vibration plate outside-spline of each of the pair of vibration-lead plates.

6. The vibration-lead plate according to claim 4 , wherein the coil plate-spline, the edge-spline, and the vibration plate outside-spline of each of the pair of vibration-lead plates are leaned toward one side based on a center point in a length direction and formed.

7. The vibration-lead plate according to claim 4 , wherein in a state in which the pair of the vibration-lead plates are located and arranged, the pair of the vibration-lead plates are symmetrical to each other left and right and up and down based on a center line of each of horizontal and vertical directions.

8. The vibration-lead plate according to claim 2 , wherein the vibration-lead plate further comprises a vibration plate inside-spline adhered to an inside part of the vibration plate edge.
