PIEZOELECTRIC CERAMIC DUAL-FREQUENCY EARPHONE STRUCTURE |
摘要 |
A piezoelectric ceramic dual-frequency earphone structure includes an earphone housing, a dynamic transducer, a piezoelectric ceramic transducer and a circuit board. The piezoelectric ceramic transducer is installed in the receiving region. The piezoelectric ceramic transducer is connected to the dynamic transducer via a support unit and a positioning unit. The circuit board is assembled in the receiving region and connected to acoustic signal cables. The acoustic signal cables are connected to a dynamic voice coil of the dynamic transducer and the piezoelectric ceramic transducer. When electric signals are applied to a ceramic membrane of the piezoelectric ceramic transducer, a metal sheet of the piezoelectric ceramic transducer is vibrated to generate high frequency sound, and the high frequency sound are then mixed with the sound from the dynamic transducer. |
