    • A headphone has a speaker unit with a diaphragm and a driving source that vibrates the diaphragm along a driving axis that passes through the speaker unit. The speaker unit has a first face and an opposing second face along the driving axis. The diaphragm and the driving source are installed in the speaker unit between the first and second faces. First and second weighting members are fixed as being in contact with the first and second faces, respectively. The speaker unit and the weighting members are installed in a hosing. At least either of the weighting members is fixed to the housing. The speaker unit is installed in the housing via the weighting members so that the speaker unit is not in direct contact with the housing. The weighting members have a higher specific gravity than the housing.
    • 耳机具有具有隔膜的扬声器单元和驱动源,其沿着穿过扬声器单元的驱动轴使隔膜振动。 扬声器单元具有沿驱动轴线的第一面和相对的第二面。 隔膜和驱动源安装在第一和第二面之间的扬声器单元中。 第一和第二加权构件分别固定为与第一和第二面接触。 扬声器单元和称重构件安装在一个软管中。 至少任一个加权构件固定在壳体上。 扬声器单元经由加重构件安装在壳体中,使得扬声器单元不与壳体直接接触。 加权构件具有比壳体更高的比重。
