    摘要： A miniaturized speaker apparatus including a cabinet to which a first speaker unit for reproducing a low frequency range is installed; second speaker units for reproducing a medium frequency range and/or a high frequency range; and supporting members for supporting the second speaker units on their tip end sides, the supporting members being supported by the cabinet so as to rotatably move between a first position, where the second speaker units are spaced apart from the cabinet, and a second position, where the second speaker units are positioned on the cabinet side making the speaker apparatus convenient for carrying.

    摘要： A speaker system has a first baffle (2) supporting a first speaker unit for producing sounds in a first frequency range (low frequencies), at least one second baffle (27L), (27R) supporting a second speaker unit for producing sounds in a second frequency range which is higher than the first frequency range (middle and/or high frequencies), the second baffles (27L), (27R) being smaller than the first baffles (2). The second baffle (27L), (27R) are spaced a predetermined distance from the first baffle (2). The speaker system has a reduced baffle effect, and increases direct sounds radiated directly from the speaker units, as compared with indirect sounds radiated backwards from a baffle, thereby improving frequency characteristics in the middle frequencies and providing excellent sound image localization.
