<p>PROBLEM TO BE SOLVED: To provide a loudspeaker converter that can be built in an audio product of smaller or thinner form, while achieving a desired acoustic output and high fidelity.SOLUTION: A thin loudspeaker converter 10a includes a frame 11, which is coupled with a T yoke 12 to form a ventilation pole piece opening 22. A diaphragm 18 has a convex dome in the frame 11 via a surround suspension 16, coupled with a voice coil former 21 via a coupler 20, and the coupler 20 is connected between the diaphragm 18 and voice coil former 21. The diaphragm 18 is attached to a spider suspension 17 that is attached to a top plate 14 and also suspended by the spider suspension 17, and arranged in a plane above the surround suspension 16, so as to attain the stability for minimizing the oscillation of a voice coil 19.</p> |
