ABSTRACT:
The present invention relates to a structure of speaker which includes a disk body directly connected to the opening of a sound coil in a speaker. The disk body has a couple of reinforcing heat-sinking rings, and the opening edge of disk body is connected with the belly plate of speaker. The speaker of such structure is effective to radiate heat produced from the sound coil through the direct connection of the disk body with the sound coil and due to the light-weighted and thin metallic disk body having effective heat radiation so as to prolong the duration of play as well as the life span of the speaker. The end of the disk body projecting in the sound coil and the other end connected to the belly plate increases the capacity of resistance of the vibration wave and therefore one single speaker may provide an output as a tweeter and a woofer. The disk body directly connecting to the sound coil may give high fidelity of the vibration wave arising from movement of sound coil so as to improve sound quality.
