Title: Capacitor microphone output circuit
Inventor: ENDO OSAMU
IPC: H04R3/00
Filed: 1986-07-16
Abstract: PURPOSE:To decrease a noise and to hold a circuit highly stably by making the constant voltage of a constant voltage circuit into an operating voltage, supplying it to a capacitor microphone unit and impressing it to an FET as a bias voltage. CONSTITUTION:A constant voltage outputted from a constant voltage circuit 10 is impressed through a high resistance 11 as one edge of a capacitor microphone unit (CMU) 12 and the bias voltage of an FET 13. The CMU 12 outputs the signal of a electrostatic capacity change to the gate terminal of the FET 13 corresponding to the sound wave to be inputted, and to the source terminal of the FET 13, the impedance-converted electric signal is outputted. The electric signal is converted by a transformer 16 and outputted from an output terminal 17. Thus, since a coupling capacitor is not needed and one high resistance is sufficient, the noise can be suppressed and the stable output can be obtained.

IPC: G01P3/64
Filed: 1982-09-27
Abstract: PURPOSE:To detect the finger attack speed stably at a high accuracy with a compact construction by employing a digital arithmetic circuit equivalent to a time constant circuit with a resistance and a capacity. CONSTITUTION:When a switch S1 is closed in response to finger attacking, a pulse corresponding to the keying timing is outputted to a data selection circuit 6 through an FF1, an FF3, a NOT circuit 4, an AND gate 5 and the like to select a numeral N which is memorized into a memory circuit 7. The multiplication of the memory contents by a specific coefficient with a multiplier 8, the selection of results of the multiplier 8 with the circuit 6 and the memory of selected output with the circuit 7 are done circularly to perform a digital computation equivalent of a time constant circuit with a resistance and capacity. The results of the computation are memorized into a memory circuit 9 whose latching is controlled with the FF2 for detecting the closing of a switch S2 delayed from the switch S1 in the keying and detected depending on the keying speed. Thus, the detection of the finger attack speed can be done stably at a high accuracy with a small LSI structure requiring none or such resistance, capacity and the like.
