REGMET electrical components German REGMET models REGMET prices

REGMET electrical components are products whose raw material molecular composition is not altered during factory processing, and can be referred to as components. Components belong to devices that do not require an energy source. They include: resistors, capacitors, and inductors. Circuit-type components include diodes and resistors; connection-type components include connectors, sockets, connecting cables, and printed circuit boards (PCB). Devices are products whose raw material molecular structure is altered during factory production and processing. Devices are divided into active devices and discrete devices. The main characteristic of active devices is that they generate or consume electrical energy and require an external power supply. Discrete devices are divided into bipolar junction transistors, field-effect transistors, thyristors, semiconductor resistors, and capacitors. shi

REGMET electrical component functions

Antennas radiate radio waves and also receive radio waves. However, what the transmitter feeds into the antenna via the feed line is not radio waves, nor can the receiving antenna directly feed radio waves into the receiver via the feed line; an energy conversion process must occur in between. Below, we take radio communication equipment as an example to analyze the signal transmission process, thereby illustrating the energy conversion role of the antenna. At the transmitting end, the modulated high-frequency oscillating current (energy) generated by the transmitter is input to the transmitting antenna via the feeding device (the feeding device may transmit current waves or electromagnetic waves directly, depending on frequency and form). The transmitting antenna converts the high-frequency current or guided wave (energy) into radio waves—free electromagnetic waves (energy)—radiating them into the surrounding space. At the receiving end, radio waves (energy) are converted by the receiving antenna into high-frequency current or guided wave (energy), which is transmitted to the receiver via the feeding device. From the above process, it can be seen that the antenna is not only a device for radiating and receiving radio waves, but also an energy converter, serving as the interface device between the circuit and space.

REGMET electrical component structure

Common electrodynamic cone paper-cone loudspeakers. Electrodynamic cone loudspeakers were formerly commonly referred to as paper-cone loudspeakers. Although the diaphragm is still primarily made of paper cone, many polymer material diaphragms and metal diaphragms have emerged, making the term "cone loudspeaker" more accurate. A cone paper-cone loudspeaker generally consists of three major parts: the magnetic circuit system (permanent magnet, core pole, magnetic plate), the vibration system (paper cone, voice coil), and the support auxiliary system (centering spider, basket, surround). 1. Voice coil: The voice coil is the drive unit of the cone paper-cone loudspeaker. It is made of very fine copper wire wound in two layers around a paper tube, typically with dozens of turns, also known as a coil. It is placed in the magnetic gap formed by the magnetic core pole and the magnetic plate. The voice coil is fixed to the paper cone. When an audio current signal is applied to the voice coil, the vibration of the voice coil drives the vibration of the paper cone. 2. Paper cone: There are many types of materials used for the cone diaphragm of cone paper-cone loudspeakers, generally falling into two categories: natural fibers and synthetic fibers. Natural fibers often include cotton, wood, wool, and silk, while synthetic fibers include rayon, nylon, and fiberglass. Since the paper cone is the sound-radiating element of the loudspeaker, it largely determines the acoustic performance of the loudspeaker. Therefore, regardless of the type of paper cone, it must be lightweight and have good rigidity, and must not deform due to changes in ambient temperature or humidity. 3. Surround: The surround is designed to ensure the axial movement of the paper cone along the loudspeaker axis and restrict lateral movement, while also preventing air leakage between the front and rear of the paper cone. In addition to materials commonly used for paper cones, the surround may also use plastics and natural rubber, which are thermally bonded to the paper cone. 6. Centering spider: The centering spider supports the junction of the voice coil and the paper cone, ensuring it remains vertical and not skewed. The centering spider has many concentric rings, allowing the voice coil to move freely up and down in the magnetic gap without lateral movement, ensuring the voice coil does not touch the magnetic plate. The dust cap on the centering spider prevents external dust from entering the magnetic gap, avoiding friction between dust and the voice coil, which could cause abnormal sounds from the loudspeaker. A typical loudspeaker consists of a magnet, frame, centering spider, molded surround, and cone paper cone.

REGMET electrical component characteristics

Resolution refers to the ability of a sensor to detect the smallest change in the measured quantity. That is, if the input changes slowly from a non-zero value, the sensor's output will not change when the input change does not exceed a certain value, meaning the sensor cannot resolve this change in the input. Only when the change in the input exceeds the resolution will the output change. Typically, the resolution at various points within the full-scale range of a sensor is not identical. Therefore, the maximum change in input within the full scale that causes a step change in the output is commonly used as the indicator for measuring resolution. If the above indicator is expressed as a percentage of the full scale, it is called resolution. Resolution has a negative correlation with sensor stability.
