The dome is provided with a through hole in communication with the first surface and the second surface, and the through hole is adjacent to edges of the dome but does not reach the edges of the dome. The present disclosure further provides a speaker including the diaphragm. The diaphragm and the speaker according to the present disclosure have the advantages of ensuring the strength of the dome while ensuring the leakage of the glue inside the speaker.
