摘要

The housing for a loud speaker or the like is such that the housing, or at least the cover placed in front of the loud speaker in the sound emission direction, is made of an open pore metal foam material. The housing may have a lining or insert which fills the space behind the loud speaker in the housing and embeds the loud speaker. This is also made of an open pore metal foam material.
