Technical Examples

An acoustic structure of seat back in which speaker units are provided in a padding of the seat back. The padding includes: a frontal backrest surface area which is recessed backwardly of the seat back; and securing holes formed in that frontal backrest surface area. An enclosure of each speaker unit, in which each speaker is securely accommodated, is secured in each of the securing holes. A sound-conductive cushion element is juxtaposed on the foregoing recessed frontal backrest surface area of padding so as to lie on a frontal side of each of the speaker units. The sound-conductive cushion element may be of a network structure to not only provide an improved back support touch, but also achieve an improved conductivity of sounds from the speaker units to a user's back portion. Those padding and sound-conductive cushion element are covered with a trim cover assembly.
