    • An acoustic pickup transducer device for converting sounds produced by a musical instrument into electrical signals proportional in amplitude and frequency to the instrument sounds includes a housing which has protruding therefrom a suction cup for removably attaching the device to an instrument, and a microphone interconnected through interface circuitry including a volume control potentiometer within the housing to an audio output signal jack. In a preferred embodiment, the microphone is fastened to the outer end of a flexible “gooseneck” stalk which extends from the housing at an angle adjustable by manually bending the stalk to a desired shape, which is retained by a bent wire within the stalk, thus enabling adjustment of the direction of peak sound responsivity or directivity over a wide range of angles. Preferably, the microphone is an electret type supplied with a D.C. bias voltage by a coin-cell battery within the housing.
    • 一种用于将由乐器产生的声音转换为与振动和频率成正比的乐器声音的声学拾音传感器装置包括:一个外壳,其具有从其上突出的用于将该装置可移除地附接到仪器的吸盘,以及通过接口互连的麦克风 电路包括在外壳内的音量控制电位器到音频输出信号插孔。 在一个优选实施例中,麦克风被紧固到柔性“鹅颈管”杆的外端,该弹性杆从壳体以一定的角度延伸,该角度可通过手动将杆弯曲成所需的形状,所述形状由茎内的弯曲线保持, 从而能够在宽的角度范围内调整峰值声音响应性或方向性的方向。 优选地,麦克风是由壳体内的纽扣电池提供的直流偏压的驻极体类型。

    • A passive feedback mechanism by which sound produced by a musical instrument is enhanced by utilizing the reverberations from the sound to dynamically and passively alter the magnetic field in the vicinity of an electronic pickup is disclosed. This is accomplished by utilizing a component or material adhered to the instrument with the property to alter the magnetic field as the material vibrates in response to sound reverberation, one embodiment being a ferromagnetic surface coating. An electromagnetic pickup, sensitive to these variations in the magnetic field, is installed on or within the instrument. The changes in the magnetic field, in response to the music, are captured by the pickup and transformed into an electric signal with thus produce a unique and enhanced sound.
    • 公开了通过利用来自声音的混响来动态地和被动地改变电子拾音器附近的磁场来增强乐器产生的声音的无源反馈机制。 这是通过利用粘附到仪器的组件或材料来实现的,该材料具有当材料响应于声音混响而振动时改变磁场的性质,一个实施例是铁磁性表面涂层。 对磁场中这些变化敏感的电磁拾取器安装在仪器上或仪器内部。 响应于音乐,磁场的变化由拾取器捕获并转换成电信号,从而产生独特和增强的声音。
