Abstract: An acoustic device includes a housing, a loudspeaker, a terminal provided for the housing, an identifying section that specifies an external unit mounted on the terminal, and a control section that determines a control content corresponding to the external unit identified by the identifying section and controls the loudspeaker according to the determined control content.

Abstract: To reduce the transmission of vibrations from a body frame to a rotary switch, thereby preventing any trouble in the rotary switch and reliably maintaining the function and performance of the rotary switch. A side stand device includes a side stand bracket mounted on the body frame. A side stand is rotatably mounted through a pivot shaft to the bracket, and a rotary switch is provided in coaxial relationship with the pivot bolt through a securing bolt. A sheet is interposed between the rotary switch and the pivot bolt, and a tube and a sheet are interposed between the rotary switch and the securing bolt. The sheets and the tube are formed from rubber members. A cushion member is interposed between an engaging member of an inner rotor in the rotary switch and a locking hole of the side stand. The cushion member is formed from a rubber member.

Abstract: An apparatus for controlling an ignition timing of an engine is capable of reducing or preventing occurrences of backfires. The apparatus includes a no-load deceleration state detector for detecting that an engine is in a no-load deceleration state. An engine speed detector detects an engine speed. An advanced timing setting unit sets an advanced ignition timing (retard amount) in situations where the occurrence of backfires are likely, such as during the no-load deceleration state. A converter 105 determines an ignition angle &thgr;ig on the basis of an output pulse of a pulse generator and an advance amount provided by the advanced ignition timing setting unit.
