Title:
SPEAKER AND ELECTRONIC TERMINAL
Document Type and Number:
WIPO Patent Application WO/2022/088277
Kind Code:
A1
Abstract:
A speaker and an electronic terminal, comprising a basket provided with an accommodating space, a vibration system fixed on the basked, a magnetic circuit used to drive the vibration system, and a flexible circuit board used for electrical connection with the vibration system. The basket comprises a steel ring that forms an accommodating space and a plurality of welding plates fixed on the steel ring. The welding plates extend at least partially towards the accommodating space and/or the welding plates extend at least partially away from the accommodating space, and the flexible circuit board is welded to the welding plates. Because the welding plates extend at least partially toward the accommodating space and/or the welding plates extend at least partially away from the accommodating space and the flexible circuit board is welded to the welding plates, the area where the welding plates can be welded to the flexible circuit board is therefore greater than the area of a single steel ring in contact with the flexible circuit board. Thus, the flexible circuit board can be stably welded on the welding plate and the rate of dry joints is greatly reduced, causing the sound quality of the loudspeaker to be more stable.
