Abstract: The present utility model relates to the technical field of acoustoelectric conversion. Provided is a speaker, which comprises: a vibration system, a magnetic circuit system, and a basket. The vibration system comprises a diaphragm fixedly provided on the basket, a voice coil inserted into a magnetic gap, and a frame connected between the diaphragm and the voice coil. The voice coil is provided with a voice coil lead. The speaker also comprises a flexible circuit board fixed on the basket and connecting the voice coil to an external circuit. The frame is extended towards the voice coil to form a connecting plate. The voice coil is provided above the connecting plate. The flexible circuit board is provided below the connecting plate. An avoidance hole is provided on the connecting plate. The voice coil is electrically connected to a solder pad of the flexible circuit board via the avoidance hole. The speaker is characterized in that the frame also comprises a baffle provided as bent and extended from the side of the connecting plate away from the flexible circuit board and arranged beside the voice coil lead. The present technical solution is used for solving the problem in the prior art in which a voice coil lead becomes disconnected and fails due to being vibrated by a voice coil, and further solving the technical problem of a voice coil and a diaphragm vibrating out of sync.
