  • Timbre modulation circuit for electronic musical instruments
    Patent number: 4492142
    Abstract: A timbre modulation circuit for an electronic musical instrument having an automatic rhythm accompaniment system. The timbre modulation circuit is provided in a musical scale tone signal path and includes a means for generating a control pulse series synchronized with an automatic rhythm sound generation timing and a variable timbre circuit responsive to the control pulse series whereby the timbre characteristics are caused to vary in response to the control pulse series thereby modulating the timbre of the musical scale tones.

  • Methods of fabricating a miniature high frequency coil assembly or transformer
    Patent number: 4425702
    Abstract: An external core member is mounted on a dielectric substrate. The external core member is made of a magnetic material and is formed with a through bore. A coil member is disposed on the substrate and within the through bore. An elastic material casting is formed in the through bore and about the coil member, and having a core receiving bore formed therein. The core receiving bore is arranged coaxially with the longitudinal axis of the coil member so as to extend through the coil member at its center portion. A movable core of a magnetic material is movably retained in the core receiving bore.

  • Control circuitry for a voltage-controlled type electronic musical instrument
    Patent number: 4012980
    Abstract: This invention discloses control circuitry for an electronic musical instrument including a keyboard, a voltage divider circuit coupled to the keyboard to provide a pitch determining voltage signal corresponding to a depressed key, a storage capacitor for storing the pitch determining voltage signal, voltage-controlled tone signal generating means responsive to the pitch determining voltage signal and adapted to produce a tone signal corresponding to the depressed key, and control voltage waveform generating means responsive to a trigger signal and adapted to produce a control voltage waveform which is coupled to the voltage-controlled tone signal generating means so as to control the tone signal to be generated thereby.
