(A SPEAKER HAVING BOBBIN WOUND HEXAGONAL SECTION VOICE COIL) having a bobbin member in which a voice coil of a hexagonal section is wound.

摘要

The present invention relates to a speaker having a voice coil having a hexagonal cross section, in which a voice coil coiled on a bobbin is formed in a hexagonal section so that a gap between the voice coils is removed so that a suddenly high level signal from the outside is applied to the voice coil , The force applied to the voice coil is dispersed and the coupling between the voice coils is strengthened to prevent the voice coil from being released, thereby improving the reliability of the speaker.
