Abstract

The invention discloses a centering disk, which is of a multi-layer structure formed by compounding a plurality of material layers or a multi-layer structure formed by compounding a plurality of material layers and a glue layer, and comprises a conductive layer positioned in a central area. The centering disk comprises a connecting cantilever, the connecting cantilever is connected with a first fixing part, the connecting cantilever comprises root parts and a cantilever body, the root parts are located at the two ends of the cantilever body, the first fixing part is connected with the root part of one end of the cantilever body, and the conducting layer of the root part is provided with a hollow area. Compared with the prior art, the centering disk has the advantages that the problems thatan integral copper layer is large in root rigidity, maximum in stress borne by the root and prone to fatigue fracture failure are solved, the structural rigidity of the root area is reduced, stress is reasonably distributed, the maximum stress borne by the root is reduced, and the anti-fatigue performance of the centering disk is improved.

Description

technical field

[0001] The invention relates to a centering strut and a loudspeaker with the same, belonging to the field of electroacoustic technology. Background technique

[0002] The existing ultra-linear loudspeaker includes: auxiliary system, magnetic circuit system and vibration system, the magnetic circuit system is provided with a magnetic gap, the vibration system includes a diaphragm, a centering strut and a voice coil combined with the diaphragm, and the voice coil is arranged on In the magnetic gap, the current change in the voice coil arranged in the magnetic gap causes the voice coil to vibrate under the action of the magnetic field force, driving the diaphragm to vibrate and produce sound. The centering strut is one of the basic components of the super linear loudspeaker. Its function is mainly to ensure the correct position of the voice coil in the magnetic gap, to keep the voice coil under force, and the vibration system only reciprocates along the axial di...
