Title:
MOVING MAGNET-TYPE LOUDSPEAKER
Document Type and Number:
WIPO Patent Application WO/2018/170939
Kind Code:
A1
Abstract:
Disclosed is a moving magnet-type loudspeaker, comprising a housing (12a; 10b), which housing (10a; 10b) accommodates a vibrating diaphragm and a vibrator arranged in parallel with the vibrating diaphragm, with the vibrator comprising a voice coil (34a), wherein a driving magnet (24a) is fixed on the vibrating diaphragm; the voice coil (34a) forms an electromagnet after being powered on, and generates an interactive force with the driving magnet (24a) so as to drive the vibrating diaphragm to vibrate and emit sound; a position, corresponding to the driving magnet (24a), on the vibrating diaphragm, is provided with a vertical penetrating hole (200), with the driving magnet (24a) being mounted in the vertical penetrating hole (200); a motor magnet (26a) is also fixed on the housing; the voice coil (34a) is fixed on a basket (30a), with an elastic support member (39) respectively fixed at two ends of the basket (30a),, the elastic support member (39) being provided with an elastic deformation space in a horizontal direction; and a magnetic induction line of the motor magnet (26a) cuts the voice coil (34a), thereby pushing the vibrator to vibrate in a horizontal direction. The moving magnet-type loudspeaker has a good high-frequency transient response, can conveniently adjust the vibrating space of the vibrating diaphragm, and is high in terms of space utilization rate.
