pulsotronic electrical components Germany pulsotronic model pulsotronic price

pulsotronic electrical components are transducers that convert electrical signals into acoustic signals. The performance of the speaker greatly affects sound quality. Speakers are the weakest component in audio equipment, yet they are the most critical for sound effects. There is a wide variety 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.
