Abstract

PURPOSE:To prevent sounds of a speaker unit from reaching user's ears directly and obtain a sufficient acoustic pressure of the low sound, by providing a folded horn part in the housing. CONSTITUTION:A folded horn part 5 is formed in the front of a speaker unit 2 in a housing 3. Thus, the distance of the speaker unit 2 from user's ears is held in a certain degree, and sounds reaching them directly are reduced, and therefore, a natural aural impression is obtained. Further, resonance of the horn is used to obtain a sufficient acoustic pressure of the low sound.
