Abstract (en)
[origin: WO2018039883A1] A suspension arm used in a speaker, such as an ultra slim speaker, is provided. The suspension arm includes a peripheral portion, a central portion and a connection portion connecting the peripheral portion to the central portion. The connection portion includes at least one smooth curve segment, and a voice coil protrudes from a hole defined by the central portion. The central portion is designed to have relatively large area to enable area of the voice coil to be larger, so as to avoid mechanical touch and obtain a greater power.
