AI Technical Summary

Problems solved by technology

In the scenario where multiple speakers are applied, the magnetic field strength generated by the magnetic circuit system in a conventional single speaker is limited, and it is difficult to continue to improve the loudness and other performance of the speaker after it has been improved to a certain extent; and when some speakers are damaged or do not work, When only a single speaker is working, the magnetic circuit system of the non-working speaker is idle, resulting in a waste of resources

Abstract

The present invention relates to a magnetic circuit system and a sound producing device. The magnetic circuit system comprises: a bowl-shaped frame provided with a support portion at a central location thereof; a first magnet and a first top plate sequentially disposed at a surface of the support portion; and a second magnet and a second top plate sequentially disposed at a surface of the support portion facing away from the first magnet, the S pole of the first magnet opposing the N pole of the second magnet. The bowl-shaped frame further has a side wall located at the periphery of the support portion and there is a gap between the side wall and each of the first magnet and the second magnet. Outer surfaces of the first top plate and the second top plate do not extend beyond end surfaces of the bowl-shaped frame enclosed and defined by the side wall.

Description

technical field [0001] The invention belongs to the technical field of acoustic-electric transduction, and more specifically, the invention relates to a magnetic circuit system and a sound generating device. Background technique [0002] The loudspeaker is a transducing device that converts electrical signals into acoustic signals. Audio power uses electromagnetic, piezoelectric or electrostatic effects to make the cone or diaphragm vibrate and resonate with the surrounding air to produce sound. The loudspeaker is the weakest part in the audio equipment, but it is the most important part for the sound effect. [0003] In order to improve the shape of the internal magnetic force lines, the existing loudspeakers usually adopt the washer and pot frame structure. The washer is usually bonded to the magnet, and the pot frame has the functions of correcting the magnetic force line and supporting the magnet. In the scenario where multiple speakers are applied, the magnetic field s...
