OBZOR electrical components Germany OBZOR model OBZOR price

OBZOR electrical components are transducers that convert electrical signals into acoustic signals. The performance of the speaker greatly affects sound quality. In audio equipment, the speaker is the weakest component, yet it is the most critical for audio performance. There are many types of speakers with significant price differences. Audio electrical energy causes the paper cone or diaphragm to vibrate through electromagnetic, piezoelectric, or electrostatic effects, resonating with the surrounding air to produce sound. Plastic speaker enclosures, due to their thin walls and inability to overcome resonance, offer poor sound quality (although some well-designed plastic speakers are far superior to low-quality wooden ones); wooden enclosures reduce coloration caused by box resonance, generally providing better sound quality than plastic ones. Multimedia speakers typically use a two-way, two-unit design: a smaller speaker handles mid-to-high frequencies, while a larger one handles mid-to-low frequencies. When selecting speakers, consider the materials of these drivers: the tweeters in active multimedia speakers mainly use soft dome designs (such as titanium film domes for analog sources), which pair with digital sources to reduce the harshness of high-frequency signals, providing a cool, delicate, and ethereal sound. Current multimedia speakers mostly use soft dome tweeters with higher-quality silk films and lower-cost PV films.

OBZOR electrical component principle

The main principle of a diode is the unidirectional conductivity of the PN junction; adding leads and encapsulation to the PN junction forms a diode. A crystal diode consists of a PN junction formed by P-type and N-type semiconductors. A space charge layer forms on both sides of the interface, establishing a built-in electric field. When no external voltage is applied, the diffusion current caused by the carrier concentration difference across the PN junction equals the drift current caused by the built-in electric field, resulting in electrical equilibrium. When a forward bias voltage is applied, the mutual cancellation of the external and built-in electric fields increases the carrier diffusion current, causing a forward current. When a reverse bias voltage is applied, the external and built-in electric fields reinforce each other, forming a reverse saturation current within a certain reverse voltage range that is independent of the reverse bias voltage value. When the applied reverse voltage reaches a certain level, the electric field strength in the space charge layer of the PN junction reaches a critical value, triggering a carrier multiplication process that generates a large number of electron-hole pairs and a significant reverse breakdown current, known as diode breakdown. Reverse breakdown of the PN junction is classified into Zener breakdown and avalanche breakdown.

OBZOR electrical component applications

Basic circuits in analog integrated circuits include current sources, single-stage amplifiers, filters, feedback circuits, and current mirrors. Higher-level basic circuits composed of these include operational amplifiers and comparators, while even higher-level circuits include switched-capacitor circuits, phase-locked loops, and ADC/DAC. Based on the response relationship between output and input signals, analog integrated circuits are divided into linear and non-linear categories. The former exhibits a linear response, where the output signal shape resembles the input but is amplified by a fixed coefficient. Non-linear integrated circuits exhibit a non-linear response, such as square or logarithmic relationships, hence the term non-linear circuits. Common non-linear circuits include oscillators, timers, and phase-locked loops. Typical applications of analog integrated circuits are shown below: external natural signals collected by various sensors (temperature, humidity, optical, piezoelectric, acoustic, etc.) or antennas are pre-processed by analog circuits and converted into suitable digital signals for input into digital systems; signals processed by the digital system are then post-processed by analog circuits and converted into analog outputs such as sound, images, or radio waves.

OBZOR electrical component applications

Light-emitting diodes are widely used in many fields. The following outlines their main applications: (1) Applications in consumer electronics: Light-emitting diodes are generally used in consumer electronics as backlight sources for screens or for display and lighting purposes. From large LCD TVs and computer monitors to media players MP3, MP4, and mobile phones, light-emitting diodes are used as screen backlights. (2) Applications in automobiles and heavy machinery: Light-emitting diodes are extensively used in automobiles and heavy machinery. Turn signals, interior lighting, instrument panel lighting, headlights, indicator lights, brake lights, and tail lights in automobiles and heavy machinery all utilize light-emitting diodes. This is mainly because light-emitting diodes offer fast response times and long service life (the lifespan of light-emitting diodes is generally longer than that of automobiles and heavy machinery). (3) Applications in coal mines: Due to characteristics such as high efficiency, low energy consumption, long lifespan, and high luminous intensity compared to conventional light-emitting devices, light-emitting diodes are used in miner's lamps and underground lighting equipment. Although not yet fully widespread, they will soon see broad adoption, and light-emitting diodes will replace conventional light-emitting devices in coal mining applications. (13) Urban decorative lighting: In today's bustling commercial era, neon lights are an important symbol of urban prosperity, but they have many drawbacks, such as insufficient lifespan. Therefore, replacing neon lights with light-emitting diodes offers many advantages. Compared to neon lights, light-emitting diodes not only have a longer lifespan but also feature energy savings, simple drive and control, and maintenance-free operation. The replacement of neon lights with light-emitting diodes is an inevitable trend in the development of lighting equipment.
