    • The present invention concerns an acoustic transducer capable of converting a sound signal into an electric signal. The transducer comprises a mobile element that is movable under the effect of the sound signal, a fixed element opposite the mobile element, a recess (4), and a dissipative element (3) interposed between the mobile element and the fixed element. The coupled system formed in this way has a natural frequency corresponding to a resonance frequency of the transducer at which the sensitivity of same is at a maximum. The mobile element, the fixed element, the dissipative element and the recess are configured such that the quality factor of the acoustic transducer is greater than two. The recess (4) has a straight prismatic or cylindrical or frustoconical general shape, the mobile element forming a first base of the prism, cylinder or frustum, the fixed element being disposed inside said prism, cylinder or frustum, over the second base of the prism, cylinder or frustum. Such a transducer also incorporates an analogue filtering function for filtering the signal around the natural frequency of same.

    • A speaker (308) comprises a support structure (560) having a circumferentially extending rim (562), a vibration member (556) configured to be displaced relative to the support structure (560) during operation of the speaker (308), and a suspension member (552) suspending the vibration member (556) relative to the support structure (560). The suspension member (552) includes a radially outer portion (702) attached to the rim (562) of the support structure (560), a radially inner platform portion (704) attached to the vibration member (556), and a plurality of beams (708). Each beam (708) of the plurality of beams (708) may extend from the radially outer portion (702) to the radially inner platform portion (704). The plurality of beams (708) is configured such that a resonant frequency of the vibration member (556) attached to the radially inner platform portion (704) of the suspension member (552) scales linearly with a beam width of the beams (708) of the plurality of beams (708).
    • 一种扬声器(308)包括支撑结构(560),其具有沿圆周延伸的边缘(562),配置成与扬声器(308)的手术过程中相对于所述支撑结构(560)移位的振动部件(556),和一个 悬挂构件(552)暂停所述振动部件(556)相对于所述支撑结构(560)。 悬挂构件(552)包括附连到所述支撑结构(560)的轮辋(562)的径向外部部分(702),附连到振动部件(556)的径向内平台部分(704),以及多个 梁(708)。 束的多元性(708)中的每一个光束(708)可从所述径向外部分(702)与径向内平台部分(704)延伸。 光束多个(708)被配置成搜索没有附接到所述悬挂构件(552)的径向内平台部分(704)的振动部件(556)的谐振频率与所述光束的光束宽度线性缩放(708) 束多个(708)。
