Compression driver is a common type of speaker unit for high-frequency sound reproduction. The working principle of a compression driver is to compress the audio signal through a small compression driver, which then transmits the signal to a small compression chamber. In the chamber, the sound waves are compressed and transmitted to a small diaphragm, which is typically made of thin metal or polyester film. The diaphragm begins to vibrate and produce high-frequency sound waves, which are then transmitted to the acoustic lens of the horn and amplified and radiated through the horn's mouth.
Compression drivers have the following advantages:
High efficiency: Compression drivers typically have higher efficiency than other types of high-frequency drivers, as they can produce greater sound output.
Low distortion: Since the diaphragm is made of lightweight material, it can vibrate faster, reducing distortion and dispersion.
High reliability: Compression drivers are usually more durable than other types of high-frequency drivers, as they have lower mechanical motion and thermal stress.
Overall, compression drivers are a high-performance and reliable type of speaker unit suitable for high-quality audio equipment.
