Abstract
A hair leather diaphragm for a loudspeaker. The acoustic impedance of the hair leather diaphragm is lower than several existing loudspeaker diaphragms and closer to the acoustic impedance of air. As a result, there is improved energy transfer from the loudspeaker to yield higher sound pressure level (SPL). The hair leather diaphragm is tough which prevents deformation caused by mechanical pressure and is thus not easily torn.
