Patent ID: 10924865

Abstract:
The present disclosure provides a speaker including a frame having an accommodating space, a vibration system and a magnetic circuit system that are accommodated in the accommodating space. The vibration system includes a first diaphragm configured to vibrate and produce sound, a voice coil located below the first diaphragm and configured to drive the first diaphragm to vibrate and produce sound, a flexible circuit board electrically connected to the voice coil and elastically supporting the voice coil, and a second diaphragm fixed to the flexible circuit board. The flexible circuit board includes a first fixing portion connected to the voice coil, a second fixing portion disposed opposite to and separately from the first fixing portion, and an elastic arm connecting the first fixing portion and the second fixing portion. An orthogonal projection of the elastic arm toward the second diaphragm is partially located within a range of the second diaphragm.
