1. An apparatus for audio signal output, comprising:
a bone conduction assembly configured to generate a bone conduction acoustic wave;
an air conduction assembly configured to generate an air conduction acoustic wave, wherein the air conduction assembly includes one or more vibration diaphragms physically connected with at least one of the bone conduction assembly or the housing, the air conduction acoustic wave generating based on the one or more vibration diaphragms and the vibration of the at least one of the bone conduction assembly or the housing when the bone conduction assembly generates the bone conduction acoustic wave, the bone conduction acoustic wave and the air conduction acoustic wave represent a same audio signal, and a phase difference between the bone conduction acoustic wave and the air conduction acoustic wave is smaller than a threshold; and
a housing configured to accommodate at least a portion of the bone conduction assembly and the air conduction assembly;
wherein at least one of the one or more vibration diaphragms includes a main portion physically connected with the bone conduction assembly and an auxiliary portion physically connected with the housing, the main portion including a base plate and a sidewall formed a sub-space to accommodate at least a portion of the bone conduction assembly; or,
at least one of the one or more vibration diaphragms includes an annular structure, an inner wall of the vibration diaphragm surrounds the bone conduction assembly, and an outer wall of the vibration diaphragm is physically connected with the housing.
