Patent abstract
Electrical signals corresponding to sound are received at a wire, and sound is generated at a speaker connected to the wire. The sound is resonated in a cavity of a shell housing the speaker, and then passed along a transmission tube toward a pinna of a user's ear without directing the sound directly toward the user's ear canal.
