<p>An audio apparatus including a housing and a piezoelectric transducer mounted in the housing so that the transducer is adjacent a user's pinna. The transducer excites vibration in the pinna to cause it to transmit an acoustic signal from the transducer to a user's inner ear. The apparatus further including a coupler coupling the transducer to the housing with the coupler approximating to a simple support for the transducer.</p> |
