摘要： A multi-input-driving loudspeaker including a frame, a diaphragm arranged on the frame, and a plurality of input driving mechanisms. Each input driving mechanism includes a voice coil and a magnetic circuit assembly for driving the voice coil to vibrate. A plurality of magnetic circuit mounting holes are arranged on the frame. A plurality of voice coil mounting holes are arranged on the diaphragm. Each of the input driving mechanisms further includes a damper. Each of the voice coils is sleeved with one of the dampers. The frame has a plurality of flanges surrounding the magnetic circuit mounting holes. Each of the dampers and each of the flanges cooperate with each other so that each damper is embedded between an inner walls of the flange corresponding therewith.

摘要： Disclosed is a multi-cone loudspeaker, including a cone assembly. The a cone assembly includes a central cone and a plurality of outer cones successively arranged in a circumferential direction of the central cone. The central cone is driven by a central driving mechanism to vibrate and sound, each of the plurality of outer cones is driven by one of outer driving mechanism to vibrate and sound. The central driving mechanism includes a central voice coil connected to the central cone, and a central magnetic driving system for driving the central voice coil, and each of the plurality of outer driving mechanism includes an outer voice coil connected to one of the plurality of outer cones, an outer damper sleeved on the outer voice coil, and an outer magnetic driving system for driving the outer voice coil.

摘要： Disclosed is a dual-cone loudspeaker, including: a frame; a cone assembly arranged on the frame and including a central cone and an outer cone; a central drive mechanism for driving the central cone to vibrate; and a plurality of outer driving mechanisms for driving the outer cone to vibrate. The outer driving mechanisms are arranged around the central drive mechanism. The central drive mechanism includes a central voice coil connected to the central cone, and a central magnetic driving system for driving the central voice coil. Each of the plurality of outer driving mechanisms comprises an outer voice coil connected to the outer cone, an outer damper sleeved on the outer voice coil, and an outer magnetic driving system for driving the outer voice coil.

摘要： The present disclosure relates to a pedestrian alert device for an electric vehicle, comprising an accelerator pedal mechanism, a controller, and a sound producing mechanism. The controller is electrically connected to the accelerator pedal mechanism and the sound producing mechanism respectively, and is disposed on the accelerator pedal mechanism. The accelerator pedal mechanism comprises an installation box, an installation base fixedly connected to the installation box, and an accelerator pedal disposed on the installation base, the installation box has a chamber, and the controller is disposed in the chamber of the installation box. The controller is electrically connected to the sound producing mechanism by a wire, and the installation box is provided with a through-hole for the wire to pass through. The pedestrian alert device for an electric vehicle has low cost and a compact structure.
