High Frequency (HF): Different specifications of high frequency voice coils are distinguished by the diameter of the diaphragm, and common sizes include:
1 inch = 25mm (25 cores)
1.4 inches = 36mm (36 cores)
1.75 inches = 44mm (44 cores)
2 inches = 50mm (50 cores)
2.5 inches = 65mm (65 cores)
3 inches = 75mm (75 cores)
The high-frequency driver is a type of audio unit in a speaker system that is used to produce high-pitched sounds. These drivers typically use small diaphragms to vibrate and generate high-frequency sound waves. The diaphragms are often made of lightweight materials such as silk, polyester film, aluminum, titanium, and so on.
High-frequency drivers are characterized by a high frequency response and can typically produce a frequency range of 2 kHz to 20 kHz. They also have high sensitivity, which means they can produce relatively loud sound with relatively low electrical power. In addition, high-frequency drivers can typically produce brighter and clearer sound, which helps to enhance the detail and accuracy of the audio.
When selecting a high-frequency driver, several parameters need to be considered, including driver size, material, design, sensitivity, rated power, and impedance, among others. Different high-frequency drivers can produce different sound effects and have different tonal characteristics.
In summary, high-frequency drivers are an important component of speaker systems and can produce high-quality high-frequency sound. Choosing the right high-frequency driver can provide better audio performance and a more excellent listening experience for a speaker system.
