Abstract:
1. A method of using an audio device for improving a user's listening experience, the audio device having a transducer for producing output sound, the method comprising the steps of: driving the transducer to produce an output sound, wherein the transducer is a mono loudspeaker; and placing the audio device against the body of the user so that the user experiences a physical response to the sound while simultaneously listening to the audio device, wherein the audio device has a second transducer for producing output sound and wherein the second transducer is a dipole loudspeaker; and driving the second transducer to produce an output sound, wherein the dipole loudspeaker lies adjacent and spaced apart from the mono loudspeaker in substantially the same plane as the mono loudspeaker and the dipole loudspeaker is disposed in a cavity which divides the dipole loudspeaker into a first portion and a second portion each of which serves as a duct, and the first portion is above the dipole loudspeaker and the second portion is below the dipole loudspeaker wherein the transducer is arranged to produce a resonance in a chest cavity of the user's body.
