Abstract: Embodiments of the present disclosure relate to the technical field of signal transmission, and in particular to a printed circuit board and a signal transmission system. In the printed circuit board, a first signal line (140) extends, by means of passing through a second hole segment (135) and a fourth hole segment (137), from one first differential signal hole pair (121) of a first column structural unit (120) to the side of a second column structural unit (130) that is away from the first column structural unit; or, a first signal line (340) extends, by means of passing through two adjacent second ground holes (332), from one first differential signal hole pair (321) of a first column structural unit (320) to the side of a second column structural unit (330) that is away from the first column structural unit (320).

Abstract: A voice playing method, a voice transmission method, a voice playing apparatus, and a voice transmission apparatus are provided. The voice playing method includes displaying a game image of a game and a voice playing object on a first user equipment to which a first account in an online game system logs on; controlling, based on the first account selecting to spectate in the game, the voice playing object to be in an on state, in which the first user equipment is enabled to play a second voice generated in association with a second account participating in the game in the online game system; and playing the second voice in the first user equipment, based on the voice playing object being in the on state and based on setting information of the second account indicating that the first account is allowed to listen to the second voice.

Abstract: Provided in embodiments of the present disclosure are a cable connection structure, a cable connection component, and an electrical interconnection system. The cable connection structure includes a conductive part and a fixing part for fixing the conductive part. The conductive part includes at least one pair of first signal conductors arranged at an interval in a first direction, and at least one pair of second signal conductors arranged at an interval in a second direction. The first signal conductor is electrically connected to a first-type cable. The second signal conductor is electrically connected to a second-type cable with a diameter greater than that of the first-type cable. The first signal conductors are electrically connected to the second signal conductors in one-to-one correspondence. A width of the first signal conductor in the first direction is less than a width of the second signal conductor in the second direction.
