Abstract
The present invention relates to a hybrid speaker, having a high-frequency tweeter and a low-frequency woofer formed on the same axis, for improving sound quality by separately emitting a high-frequency sound generated by the high-frequency tweeter and a low-frequency sound generated by the low-frequency woofer. A device according to the present invention comprises: a woofer part for generating a low-frequency sound; a tweeter part for generating a high-frequency sound; a substrate for supplying an electrical signal to coils of the woofer part and the tweeter part; a lower frame for accommodating constituent components on the same axis; and an upper frame coupled to the lower frame to form a speaker housing, and separately having a low-frequency sound emission port for emitting the low-frequency sound of the woofer part and a high-frequency sound emission port for emitting the high-frequency sound of the tweeter part. Since the hybrid speaker, according to the present invention, has a hybrid structure in which the high-frequency tweeter and the low-frequency woofer formed on the same axis are coupled, and the high-frequency tweeter and the low-frequency woofer have respective sound…
