Bone Conducting Transducer 22 x 14mm Overview Dayton Audio BCE exciters produce sound through direct vibration of the bones in the head or are capable of converting surfaces into speakers via vibration when placed on materials such as desks, walls, doors, and many other materials. Highlights - Creates sound using bone conduction - Leaves ears free for increased listener safety - Can be used as a mini tactile transducer when attached to substrates - Wide 300 to 19,000 Hz frequency response - 8 ohm impedance with 1W power handling Dayton Audio BCE-1 22 x 14mm Bone Conducting Exciter Unlike conventional transducers that use moving air to produce sound around you, Dayton Audio BCEs (bone conducting exciters) convert the electrical signal into mechanical vibrations so clean, that the brain interprets the vibrating stimulus as excellent sound. Listener's ears are left free to remain aware of their surroundings, increasing personal safety. When used against materials such as cardboard, wood, steel, and plastics, the BCE operates much like a surface exciter, capable of moving mass to produce robust sound output; much like an invisible speaker! BCEs are excellent for unique OEM sound applications and for the experimenter, where conventional speakers and exciters cannot be used due to size constraints.
