    Abstract: A motion inducing system for playing sounds over a gramophone is provided. An electrical signal such as that from a digital music player is converted to lateral movement of a surface using a linear motion transducer. The lateral movement moves the stylus of a gramophone, and the music from the digital music source is played through the horn of the gramophone.

    Abstract: A capacitive force transducer, particularly suited for use as a microphone or as a phonograph needle pick-up cartridge, comprises a diaphragm electrode insulatively held to a lip portion of a recess in a second electrode, thereby forming a capacitive detector. The lip structure of the second electrode structure has a capacitive face region diverging from a virtual pivot region at the lip where the diaphragm is pivotably affixed to the recessed electrode. In this manner, the quiescent capacitance is defined predominantly by the capacitance near the lip, which is relatively small and defined and the change in capacitance for a given deflection of the diaphragm is relatively large, thereby improving the sensitivity of the transducer. In the case of a phonographic pick-up cartridge, the pick-up needle is coupled to the diaphragm so that vibrations induced in the needle produce corresponding vibrations of the diaphragm. A batch method of fabricating the transducers comprises recessing a semiconductive wafer through a major face to define a plurality of capacitive regions around the margins of the recesses. The diaphragm is conveniently formed by a layer deposited over an insulative layer deposited on the non recessed face of the wafer. The wafer is diced to provide a batch of the transducers.

    Abstract translation: 特别适合用作麦克风或作为留声机针拾取盒的电容式力传感器包括隔离电极，绝缘地保持在第二电极中的凹部的唇部，从而形成电容式检测器。 第二电极结构的唇缘结构具有从唇部处的虚拟枢转区域发散的电容面区域，其中隔膜可枢转地固定到凹陷电极。 以这种方式，静态电容主要由边缘附近的电容限定，其相对较小并被限定，并且隔膜的给定偏转的电容变化相对较大，从而提高了换能器的灵敏度。 在拾音卡盒的情况下，拾音针被连接到隔膜，使得在针中产生的振动产生相应的隔膜振动。 制造换能器的分批方法包括通过主面凹入半导体晶片以在凹部的边缘周围限定多个电容区域。 膜片方便地由沉积在晶片的非凹面上的绝缘层上沉积的层形成。 切片晶片以提供一批换能器。
