Abstract

The present disclosure relates to a vibration transmission plate, a bone conduction sounding assembly, and an earphone. The vibration transmission plate includes: an inner ring portion; an outer ring portion; and a plurality of connecting rods connected between the inner ring portion and the outer ring portion. The connecting rod includes a rod body, a first connection portion, and a second connection portion, one end of the rod body is connected to the inner ring portion via the first connection portion. The vibration transmission plate includes a major axis and a minor axis intersecting each other, a size of the vibration transmission plate along the major axis is greater than a size along the minor axis. The vibration transmission plate further includes a first reference point located at a connection between the first connection portion and the rod body, a second reference point located at a connection between the second connection portion and the rod body, and a first reference line defined by the first reference point and the second reference point. The rod body is divided by the first reference line into a first portion and a second portion located on two sides of the first reference line, and an area ratio of the first portion to the second portion is between 0.8 and 1.2. With the above configuration, the present disclosure can reduce air conduction noise generated by the vibration transmission plate and improve a sound effect of the bone conduction sounding assembly.
