Electronic language model entertaining circuit circuit diagram
The circuit consists of a one-shot trigger and a language integrated audio circuit. 555 and R1, C2, etc. form a one-shot trigger. When the visitor touches the metal piece A, the 555 circuit is set, and the 3rd pin is high level, triggering IC2. IC2 is a language integrated circuit CIC5603. When the pin 2 has a trigger level signal, its internal memory is activated and a sound is heard through the speaker. At the same time, the two LEDs shimmer.
Monocrystalline silicon is an infrared material with excellent comprehensive cost performance. It can be divided into transmission grade and mirror grade. As a transmission grade material, optical grade Czochralski silicon (OCZ SI) is widely used in the mid infrared (1-6um) band, with an infrared transmittance of more than 50%. Zone fused monocrystalline silicon can be used in wider band (1-14um), and high-purity zone fused monocrystalline silicon (hpfz SI) can even be used in far-infrared band (greater than 30um).
Silicon single crystal is also an excellent laser mirror material. Compared with other mirror materials such as copper and molybdenum, silicon single crystal is the preferred substrate material for CO2 laser mirror because of its good thermal conductivity, excellent thermal stability, low coefficient of thermal expansion, relatively low density, low cost and easy precision processing.
