LOUDSPEAKER UNIT AND LOUDSPEAKER MODULE
Document Type and Number:
WIPO Patent Application WO/2023/217150
Kind Code:
A1
Abstract:
The present invention relates to a loudspeaker unit, comprising a first magnet, wherein a second magnet and a third magnet are respectively arranged on two sides of the first magnet, a first dome is arranged above the first magnet, the surface of the first magnet close to the first dome is arranged parallel to the first dome, and a bass cavity is formed by the first magnet and the first dome; a second dome is arranged on the side of the second magnet away from the first magnet, and the first dome has a larger area than the second dome; and a treble cavity is formed by the second magnet and the second dome, and the second magnet is also used for providing a magnetic field for the treble cavity. According to the technical solution provided by the embodiments of the present application, a small-sized combined loudspeaker unit having both a bass cavity and a treble cavity is formed, and the two cavity units jointly emit sound, so that the frequency response performance of high and low frequency bands can be mutually compensated, and the high sound quality of a full frequency band is thus realized. The present disclosure further provides a loudspeaker module comprising the loudspeaker unit.
