    摘要: The sound generator applies an envelope to the note signal. Current to the sound producing element is controlled by a series transistor whose base is driven with a signal having a frequency corresponding to the musical note. The driving voltage applied to the base has a voltage amplitude corresponding to the voltage stored in a capacitor connected through a resistor and discharging through said resistor and the base of the transistor controlling the current to the sound producer.

    摘要: A variable frequency oscillator circuit adapted for stabilization of its free-running frequency comprises a first signal synthesizing circuit, first voltage-controlled oscillator, a phase-locked loop and reference signal generator, the phase-locked loop consisting of a second signal synthesizing circuit, second voltage-controlled oscillator, phase comparator and low-pass filter. The first and second signal synthesizing circuits have the same characteristics, and the first and second voltage-controlled oscillators have the same characteristics. The reference signal and output of the second voltage-controlled oscillator are input to the phase comparator. The comparator output is applied to the first and second signal synthesizing circuits. An external signal is applied to the first signal synthesizing circuit, and the output of the first voltage-controlled oscillator acts as the output of the variable frequency oscillator circuit.The principles are applied to reading data pulses from a floppy disk.

    摘要: An electronic timepiece with voice memory includes an auto start circuit which senses the presence of an input voice and automatically controls the start of recording. Voices inputted from the outside are coded and the coded data is stored in memory. An output means reads out the memory contents and transforms the coded contents into an analog voice signal. When the incoming voice exceeds a predetermined level, the recording means is automatically started by an output from a level detector. Memory is divided into at least two regions. The first region stores coded voice data before the auto-start circuit operates and later coded voice data is recorded in the second region after the autostart circuit operates so that the initial portions of speech are not lost.
