The present invention relates to dual-frequency and bass-enhanced earphones using piezoelectric ceramic materials. According to the present invention, the dual-frequency and bass-enhanced earphones using piezoelectric ceramic materials include: an earphone case; a movable coil type speaker unit, and a piezoelectric ceramic speaker component. The earphone case includes a sound hole. The movable coil type speaker unit includes a movable coil type speaker and a circuit connection unit. The circuit connection unit and the movable coil type speaker are electrically connected. The piezoelectric ceramic speaker component is arranged between the sound hole and the movable coil type speaker unit. The piezoelectric ceramic speaker component includes a piezoelectric ceramic plate and an electrically conductive component. The electrically conductive component, piezoelectric ceramic plate, and circuit connection unit are connected. The piezoelectric ceramic plate includes multiple sound passing holes and realizes a sound effect of surrounding high sound with low sound through a combination of the piezoelectric ceramic speaker component and the movable coil type speaker unit. The present invention enables high sound definition and enables users to experience sound effects with enhanced low sound. |
