Abstract
In a voice receiving mechanism and a handset, an ear pad and a speaker are secured to a ball of a ball joint, and a grip portion supports a ball holder of the ball joint. Therefore, the ear pad, and so on are swingable in any direction relative to the grip portion, and the ear pad, can be brought into close contact with the ear. Further, a leaf spring applies a braking force to the ball. So that, even after the ear pad is separated from the ear, the orientation (direction and angle) of the ear pad, can be kept so that the ear pad can come into close contact with the ear.
