Abstract

Disclosed are a vibration diaphragm, a vibration diaphragm assembly and a loudspeaker. A centering support sheet comprises an inner fixing portion, an outer fixing portion and a connection arm, wherein the inner fixing portion and the outer fixing portion are arranged at an interval; the connection arm is provided between the inner fixing portion and the outer fixing portion; the connection arm comprises a main body portion, a first bending connection portion provided at one end of the main body portion, and a second bending connection portion provided at the other end of the main body portion; and the first bending connection portion is connected to the inner fixing portion, and the second bending connection portion is connected to the outer fixing portion. A vibration diaphragm comprises a center portion, a curved ring folding portion provided around the center portion, and a fixing portion provided around the ring folding portion, wherein the highest point of a part of the ring folding portion corresponding to the first bending connection portion is offset towards the inner fixing portion, and the highest point of a part of the ring folding portion corresponding to the second bending connection portion is offset towards the outer fixing portion. The solution of the present application uses an avoidance design for the ring folding portion, so that sufficient vibration space is provided for the ring folding portion of the vibration diaphragm, thereby satisfying the acoustic performance of a loudspeaker.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a diaphragm, a diaphragm assembly and a loudspeaker. Background technique [0002] Loudspeaker is an important acoustic component in portable electronic equipment, which is used to convert sound wave electric signal into sound signal output, and is an energy conversion device. [0003] A loudspeaker usually includes a vibration system, a magnetic circuit system and an auxiliary system, and the vibration system and the magnetic circuit system are accommodated in the auxiliary system. The vibration system generally includes a diaphragm, a strut and a voice coil combined together, wherein the diaphragm and the strut together form a diaphragm assembly, and the strut is used to connect the diaphragm and the voice coil as a whole to ensure sound The ring is vertical without skewing, which can effectively prevent the polarization of the diaphragm. At the same time, the centering s...
