摘要： The present disclosure discloses a diaphragm for radiating sound, including: a dome; a suspension surrounding the dome, including a first connecting portion adjacent to the dome and having a first surface and a second surface, a suspending portion extending from and surrounding the first connecting portion, and a second connecting portion extending from and surrounding the suspending portion. The suspending portion includes a concave part recessed along a direction from the first surface to the second surface, an inner edge connecting to the first connecting portion, and an outer edge connecting to the second connecting portion. The diaphragm further includes a stiffening layer located on the first surface of the first connecting portion, extending from the inner edge toward the dome. The present disclosure further includes a speaker incorporating the diaphragm.

摘要： The invention discloses a substrate material and a preparation method thereof, and a diaphragm. The substrate material comprises a first adhesive layer, a second adhesive layer, a first polymer material layer made of polymer material, a second polymer material layer made of polymer material, and a porous damping material layer made of porous damping material. The porous damping material layer comprises a first side surface and a second side surface arranged opposite to each other, the first polymer material layer is glued to the first side surface through the first adhesive layer, the second polymer material layer is glued to the second side surface through the second adhesive layer. The vibration amplitude of products using the substrate material of the present invention has a smaller deviation with increasing temperature, which improves stability of product performance.

摘要： The present disclosure discloses a diaphragm for radiating sound, includes: a dome part and a suspension part surrounding the dome part. The suspension part includes a first subgroup, a second subgroup, and a third subgroup arranged in a sequence, the first subgroup being close to the dome part, the third subgroup away from the dome part, and the second subgroup between the first and third subgroups. Each of the first, second, and third subgroups includes a number of patterns arranged along a circumference direction of the dome part. Selected patterns in the second subgroup are opposite to corresponding patterns in the first subgroup, and selected patterns in the second subgroup are opposite to corresponding patterns in the third subgroup; and each corner of the suspension part is provided with the first subgroup, the second subgroup and the third subgroup.
