Document Type and Number:
WIPO Patent Application WO/2021/206212
Kind Code:
A1
Abstract:
A high-performance slim speaker according to the present invention is a speaker comprising a magnetic field unit and a vibration field unit. The magnetic field unit may comprise: a lower frame that covers the lower part of the speaker and has an opening in the vertical direction; a yoke that is positioned on the lower frame and covers the opening of the lower frame; an internal magnetic body positioned on the yoke; an inner plate positioned on the inner magnetic body; an external magnetic body positioned on the yoke and disposed adjacently along the lateral circumference of the internal magnetic body; and an outer plate positioned on the external magnetic body and disposed adjacently along the lateral circumference of the inner plate, and the vibration field unit may comprise: an upper frame that covers the upper part of the speaker and has an opening in the vertical direction; a cone paper unit including a cover covering the upper frame and cone paper formed along the outer circumference of the cover; a voice coil including a bobbin coupled to the cover and a coil wound around the outer circumferential surface of the bobbin, the voice coil interposed between the internal magnetic body and the external magnetic body; a damper having one end attached to the lower part of the cone paper unit and the other end fitted and coupled to the upper frame; and a tinsel wire unit that connects the coil and a terminal receiving power and an acoustic signal from the outside so as to transmit the acoustic signal to the voice coil, wherein the damper is disposed outside the outer circumference of the magnetic field unit when viewed from the speaker in the horizontal direction so as to secure a larger free space for vertical vibration.
