A bone conduction audio apparatus includes at least one ear hook assembly. A main circuit board is provided in the ear hook assembly. Each ear hook assembly includes an operating unit, a line concentrator and a bone conduction transducer. Each operating unit is electrically connected with corresponding line concentrator by contact springs or connecting wires, and connected with the main circuit board via the line concentrator. Each bone conduction transducer is electrically connected with the main circuit board via corresponding line concentrator. A controller of the main circuit board receives touch signals from all operating units to determine and initiate relating earphone operating. The bone conduction audio apparatus adopts bilateral triggering interaction mechanism. The line concentrator is combined with the suspended bone conduction transducer.

A gearbox assembly includes a housing, a cover, a screw rod inserted through the housing along a first direction, a worm wheel integrally formed on the screw rod, and a worm arranged in the housing along a second direction perpendicular to the first direction. The worm is driven into rotation by a driving shaft, so that the worm drives the worm wheel and the screw rod into rotation through a kinetic pair. The screw rod moves a lifting mechanism attached to the screw rod in a vertical direction through screw transmission. A stop pin is arranged on the housing and positioned in the direction of extension of a free end of the driving shaft of the worm against the free end.
