    • A speaker apparatus includes a speaker unit including a magnet configured to provide a magnetic field; and a membrane disposed in the magnet field, configured to be vibratable in a first direction, and configured to emit a sound in a second direction perpendicular to the first direction; and a blocking unit disposed at the membrane, configured to block a first region of the membrane having a first height along the first direction from being exposed and configured to expose a second region of the membrane having a second height, a sum of the first and the second heights corresponds to a total height of the membrane, wherein the first height of the membrane blocked by the blocking unit is less than a half of a wavelength corresponding to a maximum frequency in a frequency domain of the sound emitted from the membrane.
    • 扬声器装置包括:扬声器单元,包括被配置为提供磁场的磁体; 以及设置在所述磁场中的膜,被配置为可沿第一方向振动,并且被配置为沿垂直于所述第一方向的第二方向发出声音; 以及设置在所述膜处的阻挡单元,被配置为阻挡具有沿着所述第一方向的第一高度的所述膜的第一区域被暴露并且被配置为暴露具有第二高度的所述膜的第二区域, 第二高度对应于膜的总高度,其中被阻挡单元阻挡的膜的第一高度小于对应于从膜发出的声音的频域中的最大频率的波长的一半。
