Snoring, saying sleep therapy device circuit diagram
This circuit can effectively stop snoring or sleepy words during sleep, use a period of time to form a conditioned reflex, and gradually eliminate these problems. As soon as the snoring person screams or the dreamer speaks a word, the circuit emits a pulse like acupuncture and electroacupuncture, which awakens the person and stops snoring or dreaming. Snoring, telling sleep therapy circuit working principle: Ont, namely optical network equipment, is a product in the xpon network access solution.

The circuit is shown in the figure. After the microphone MIC picks up the click or speech, it is amplified by a composite amplifier composed of VT1 and VT2, and the signal voltage is boosted by T, and then output by the RP.
See the figure for component selection:
Microphone MIC uses ordinary electret condenser microphone, T uses portable radio output transformer core winding, primary with Φ0.15mm enameled wire wound 80åŒ, secondary with Φ0.08mm enameled wire around 5000åŒ. The RP is a 47k potentiometer with a switch. The power supply uses two No. 5 batteries. The electrode is welded with two thin insulated wires with a thickness of about 0.5-1 mm, and the copper piece is bent into a ring around the two fingers that are not adjacent.
When using, first learn the sound from the microphone 30-5cm, adjust the RP, so that the degree of electric anesthesia between the two fingers is appropriate, then it can be put into use.
Generally speaking, an ONT is an ONU, which is an optical network terminal used at the user end.
Strictly speaking, ONT should belong to part of ONU.
The difference between an ONT and an ONU is that an ONT is an optical network terminal and is directly located at the user end, while an ONU is an optical network unit, and there may be other networks, such as Ethernet, with the user.
The ONU can be connected to the gateway device of xDSL (adsl, vdsl) or Ethernet access port, and then connected to the network terminal.
Ethernet is a computer local area network technology. The IEEE 802.3 standard organized by the IEEE establishes the technical standard for Ethernet, which specifies the content of the physical layer wiring, electronic signals, and media access layer protocol. Ethernet is currently the most commonly used LAN technology, replacing other LAN technologies such as token ring, FDDI and ARCNET.
Ethernet is the most common computer network in the real world. There are two types of Ethernet: the first type is classic Ethernet, and the second type is switched Ethernet, which uses a device called a switch to connect different computers. Classic Ethernet is the original form of Ethernet, and its operating speed ranges from 3 to 10 Mbps. Switched Ethernet is a widely used Ethernet that can run at high speeds such as 100, 1000, and 10000 Mbps. NET, Gigabit Ethernet and 10 Gigabit Ethernet.
The standard topology of Ethernet is a bus topology, but the current Fast Ethernet (100BASE-T, 1000BASE-T standards) in order to reduce conflicts, maximize the network speed and use efficiency, and use switches for network connection and organization. In this way, the topology of the Ethernet becomes a star; but logically, the Ethernet still uses the bus topology and CSMA/CD (Carrier Sense Multiple Access/Collision Detection). Bus technology.
Ethernet realizes the idea of sending information from multiple nodes in the radio system on the network. Each node must obtain a cable or channel to transmit information. It is sometimes called Ether. (The name comes from the electromagnetic radiation medium-optical ether assumed by physicists in the 19th century. Later studies proved that optical ether does not exist.) Each node has a globally unique 48-bit address, which is the MAC address assigned to the network card by the manufacturer , To ensure that all nodes on the Ethernet can identify each other. Because Ethernet is so common, many manufacturers integrate Ethernet cards directly into computer motherboards.
