Abstract

Disclosed is a moving magnet loudspeaker, comprising an enclosure (12; 10), wherein a diaphragm and a vibrator are provided in the enclosure (12; 10), the vibrator comprises a voice coil (34), and a driving magnet (24) is fixed at one side of the vibrator; the voice coil (34) is fixed on a frame (30), and an elastic support member (39) is respectively fixed at two ends of the frame (30); the side of the vibrator away from the diaphragm is provided with a motor magnet (26); and an electromagnetic induction force between the motor magnet (26) and the voice coil (34) drives the vibrator to vibrate in a horizontal direction.

Description

technical field [0001] The invention relates to the technical field of electroacoustic products, in particular to a moving magnet loudspeaker. Background technique [0002] The loudspeaker is an important acoustic component of portable electronic equipment. It is used to complete the conversion between electrical signals and sound signals. It is an energy conversion device; the linear vibration motor is a kind of motor and an important part of portable electronic equipment. To realize the function of vibration reminder. With the development of portable electronic devices, the volume requirements are getting smaller and smaller. In order to meet the above requirements, two-in-one speakers have emerged. It is to package the speaker and the vibration motor into one casing to reduce the volume of the electronic equipment. Most of the existing two-in-one speakers are dynamic speakers, and the dynamic speakers usually assemble motor magnets on the diaphragm. Limited by the vibr...
