Abstract
A speaker includes a frame, and a vibration system and a magnetic circuit system that are fixed on the frame. The vibration system includes a first vibration diaphragm fixed to the frame, a voice coil disposed on a side of the first vibration diaphragm and configured to drive the first vibration diaphragm to vibrate to produce sound, and an elastic support part for the elastic support coil. The elastic support part includes a flexible printed circuit board connecting the voice coil to an external circuit.
Claims8
A speaker, comprising:
- a frame;
- a magnetic circuit system fixed to the frame;
- a vibration system fixed to the frame, comprising:
- a first diaphragm fixedly connected to the frame;
- a voice coil disposed on a side of the first diaphragm and configured to drive the first diaphragm to vibrate to produce sound;
- and
- an elastic support part disposed on a side of the voice coil distal from the first diaphragm and configured to elastically support the voice coil, the elastic support part comprising a flexible printed circuit board, the flexible printed circuit board connecting the voice coil to an external circuit, wherein the flexible printed circuit board comprises an inner ring connected to the voice coil, an outer ring connected to the frame, a first elastic arm and a second elastic arm, both ends of the first elastic arm and the second elastic arm being connected to the inner ring and the outer ring respectively, the first elastic arm and the second elastic arm being oppositely disposed, a first conductive region electrically connected to the voice coil being disposed in the inner ring, a second conductive region electrically connected to the external circuit being disposed in the outer ring, a first conductive path is disposed in the first elastic arm, a second conductive path being disposed in the second elastic arm, and both ends of the first conductive path and the second conductive path being electrically connected to the first conductive region respectively and the second conductive region to form two conductive channels.
