The utility model discloses a piezoelectric ceramics double-frequency bass enhanced earphone, comprising an earphone housing, a moving-coil loudspeaking assembly, and a piezoelectric ceramics loudspeaking assembly. The earphone housing comprises a sound-out hole. The moving-coil loudspeaking assembly comprises a moving-coil loudspeaker and a circuit adapter unit. The circuit adapter unit is electrically connected with the moving-coil loudspeaker. The piezoelectric ceramics loudspeaking assembly is between the sound-out hole and the moving-coil loudspeaking assembly. The piezoelectric ceramics loudspeaking assembly comprises a piezoelectric ceramic piece and a conductive piece. The conductive piece is connected with the piezoelectric ceramic piece and the circuit adapter unit. The piezoelectric ceramic piece comprises a plurality of sound transmitting holes. Through combining the piezoelectric ceramics loudspeaking assembly and the moving-coil loudspeaking assembly, auditory effect of low-frequency sound waves surrounding high-frequency sound waves is achieved. Since analysis of high-pitch audio frequency is improved, a user can feel effect of enhanced bass audio frequency.
