摘要

PURPOSE: A loud speaker for a vehicle is provided to remotely sound pressure to a remote place without the decrease of the sound pressure.;CONSTITUTION: A drive unit(21) generates sound pressure by vibrating air, and a horn(22) widely diffuses the sound pressure generated in the drive unit. An equalizer(23) balances and magnifies the sound pressure inside the horn. A waveguide plate(24) transmits the sound pressure between the drive unit and the horn to a remote place. The entire length of the waveguide plate is long.;COPYRIGHT KIPO 2011
