    • A speaker apparatus is configured such that a speaker unit including a single magnetic circuit system, a plurality of vibration systems and a case is housed inside a speaker box. In the speaker unit, magnetic gaps having a magnetic field of the same magnitude are defined by a magnet holder, a magnet and a yoke in each of the vibration systems. In one vibration system and the other vibration system, voice coils are wound around voice coil bobbins in directions reverse to each other. Consequently, the vibration systems are moved in directions opposite to each other by the same force by applying the same electric signal to the voice coil in each of the vibration systems from an amplifier. Therefore, acoustic waves are radiated in the directions opposite to each other.
    • 扬声器装置被配置为使得包括单个磁路系统,多个振动系统和壳体的扬声器单元容纳在扬声器箱内。 在扬声器单元中,具有相同幅度的磁场的磁隙由每个振动系统中的磁体保持器,磁体和磁轭限定。 在一个振动系统和另一个振动系统中,音圈以相反的方向缠绕在音圈线轴上。 因此,通过对来自放大器的每个振动系统中的音圈施加相同的电信号,通过相同的力使振动系统彼此相反的方向移动。 因此,声波沿彼此相反的方向辐射。
