摘要： A speaker structure comprises a main speaker, an auxiliary speaker, a first driving mechanism, and a second driving mechanism. The auxiliary speaker is connected to the main speaker and displaceable relative to the main speaker. The first drive mechanism is configured to drive the main speaker to reciprocate in a first direction, and the second driving mechanism is configured to drive the auxiliary speaker to reciprocate in a second direction relative to the main speaker. The first driving mechanism is arranged in the main speaker, and the second driving mechanism is arranged in the main speaker. An output end of the second driving mechanism extends out of the main speaker and connected to the auxiliary speaker.
