Original Abstract Submitted
A coaxial speaker box includes a housing, a speaker unit, and a sound guide channel for guiding sound outside. The speaker unit includes a frame, a magnetic circuit system, a first vibration system, and a second vibration system. The first vibration system is disposed in the frame. The second vibration system is disposed on an outer side of the frame. A front cavity is formed among the first vibration system, the second vibration system, and the housing. The first vibration system includes a first vibrating diaphragm and a first voice coil. A coaxial full-band speaker is formed by the bass and the high pitch of the coaxial speaker box to provide high-quality sound effects. The high pitch and the bass share a side sound guide channel, and form a front cavity resonance in a bass channel to improve high-frequency sound effects.
