出し、これを計数して作動することにある。 A feature of the present invention is that it operates by detecting and counting a plurality of intermittent sounds (audio waves or ultrasonic waves) such as applause or hitting sounds.

受けて負荷１１にかかる電源電圧を開閉する。 The sound block detected by the microphone 1 is amplified by the low frequency amplifier 2. The frequency characteristics of the low frequency amplifier 2 must be appropriately designed depending on whether the target sound is an audio wave or an ultrasonic wave. Also,
It is desirable to have a volume controller so that the sensitivity can be adjusted depending on the installation location, surrounding environment, etc. Exchange-
The DC converter 3 includes a rectifier and a smoother, and performs so-called envelope detection to convert the waveform as shown in FIG. The voltage comparator 4 compares the voltage of the reference power source 5 with the peak value of the detected waveform in the AC-DC converter 3, and outputs an output when the peak value of the detected waveform is larger, as shown in FIG. It comes out nicely formatted. Note that a Schmitt circuit may be used instead of the voltage comparator 4. If the interval between the audio blocks is too short, the first monostable multicircuit 6 will not be able to output two signals within the set time of the first monostable multicircuit 6.
pulses coming in, resulting in a single pulse output. The second monostable multi-circuit 7 has a longer set time than the first monostable multi-circuit 6, and is used to set the gate time of the gate circuit 8. If the interval between audio blocks is too long, the second pulse will not arrive within the gate time. The counting control circuit 9 commands opening/closing operation when two pulses are received. The load drive circuit 10 receives commands from the counting control circuit 9 to open and close the power supply voltage applied to the load 11 .

作が少い。 FIG. 3 is a configuration diagram showing another embodiment of the present invention, and FIGS. 4A to 4C are diagrams showing the respective waveforms,
The gate pulse produced by the second monostable multicircuit 7 is triggered at the falling edge of the pulse of the first audio block. Therefore, in the gate circuit 8, there is no output when the interval between two audio blocks is too short or too long, and one output is output only when it is appropriate. In this embodiment, a counting control circuit is not required, and the load drive circuit is operated by the output pulse of the gate circuit 8. Note that this load drive circuit is equipped with maintenance means. This second embodiment is a voice switch that is operated only by two voice blocks of a predetermined volume or higher emitted at a predetermined time interval, and has an extremely simple structure and is less likely to malfunction.

く範囲に設置する工事が不要となる。 As described above, the present invention operates only when a predetermined number of sounds exceeding a predetermined volume are emitted at an appropriate repetition rate, and there are extremely few malfunctions. Using the voice switch of the present invention is extremely convenient when opening and closing a light switch in a dark place, or when opening and closing a switch in a place that is out of reach. Therefore, there is no need for construction work to install the switch within easy reach.
