The invention provides a method for automatically adjusting ringtone volume of a terminal. A time section and a ringtone volume value corresponding to the time section are saved in the terminal; the terminal acquires a present time value and judges whether the ringtone volume value corresponding to the time section which the present time value belongs to is identical to the present ringtone volume value of the terminal; if not identical, the ringtone volume value of the terminal is adjusted to be the ringtone volume value that is corresponding to the time section which the present time value belongs to; and if identical, the present ringtone volume value of the terminal is retained. The invention also provides the terminal for automatically adjusting the ringtone volume. The method and the terminal can automatically adjust the ringtone volume of the terminal and promote user experience.

The invention discloses a variable-volume additional air chamber of a constant internal pressure air spring in a vehicle air suspension system. An inner cavity of a cylinder body is uniformly divided into eight layers of cavities by separation plates in the axial direction of the cylinder body, a lug boss extends from the side wall of the cylinder body, a plunger piston which is not communicated with the cavity of the cylinder body is arranged in the lug boss, the bottom of the plunger piston is provided with a sealing cover which seals the bottom of the lug boss, and the sealing cover is connected with a main air chamber of the air spring through a pipeline; the plunger piston axially penetrates to the outside of the top of the lug boss in the axial direction of the lug boss and is connected with a stepping motor at the top, and an angle sensor is arranged on the top end surface of the plunger piston; the side surface of the plunger piston is circumferentially and uniformly distributed with eight semicircular grooves which correspond to the eight layers of cavities in length, small identical holes with eight centers on the same straight line are arranged on the side surface of the cylinder body, and the eight small holes are respectively communicated with the corresponding eight semicircular grooves and the eight layers of cavities; the angle sensor is connected with a controller after being electrically connected with a modulate circuit; and the controller is electrically connected with the stepping motor. The automatic fast change of the volume of the additional air chamber is achieved, thus the air spring obtains a wider rigidity variation range.

A high-speed wire spring forming apparatus capable of easily adjusting a coil diameter is provided that includes: a wire feeder having a pair of feeding rollers for feeding a wire to a spring forming stage via a quill serving as a wire guide; a revolving mechanism for revolving the feeding rollers about the axis of the wire to twist the wire fed out of the leading end of the quill to change the circumferential position, or angular position, of the wire; and a multiplicity of spring forming tools arranged radially on a spring forming stage, each of the spring forming tools movable in a direction substantially perpendicular to the axis of the wire.
