    • The invention relates to a low-frequency diaphragm speaker comprising a housing (10) whose sides (13, 14, 15) enclose a space (25) which is embodied at the rear of a diaphragm (3). An opening (23) is situated in a surface of the sides (13, 14, 15) delimiting the space (25). The space (25) is so small that the resonance frequency at which the vibrations of the amplifier correspond to those of the diaphragm (3) in terms of amplitude is above 200 Hz (hertz), notably above 1,000 Hz (hertz), and thus in the frequency range of a midrange or high-frequency loudspeaker. The opening (23) is configured such that at each frequency of the low-frequency diaphragm speaker air exits the space at high air speed.
    • 隔膜型低音扬声器具有壳体(10),其在它的隔膜(3)的背面所形成的壳体壁(13,14,15)封闭的容积(25)。 在限定容积(25)的壳体壁(13,14,15)的区域中存在开口(23)。 体积(25)非常小,使得放大器的振荡在尺寸方面与振动膜(3)的振动相对应的谐振频率在200Hz(赫兹)以上,特别是在1000Hz(赫兹)以上, 从而在中频或高频扬声器的频率范围内定位。 在这种情况下,开口(23)形成为使得在低频振膜的每个频率处扬声器空气以高风速离开音量。
