Speaker apparatus and sound reproduction apparatus |
摘要 |
A speaker apparatus includes a speaker unit, a passive radiator unit, and a front baffle on which the speaker unit and the passive radiator unit are mounted to form a portion of a speaker box and a back plate. A closed front chamber is formed by the front baffle for coupling the sound output generated from the back of the speaker unit with the passive radiator unit. A closed rear chamber is formed by the front baffle and the back plate for confining sound output generated from the front of the speaker unit. The speaker unit is disposed in a direction opposite to the direction of passive radiator unit, or in a direction approximately opposite.
