Abstract

An apparatus including an air-conduction transducer and a bone conduction transducer. The air-conduction transducer is configured to convert a first frequency band component of an electrical audio signal into acoustic energy to be delivered to an ear canal of a user. The bone conduction transducer is configured to convert a second, at least partially different, frequency band component of the electrical audio signal into mechanical energy to be delivered to a skull of the user. The apparatus is configured to deliver both forms of the energies to the user at a substantially same time to provide a combined audio delivery result to the user.
