What Is a Vibratory Plate?
A vibratory plate is a component used for the conversion of sound waves or electrical signals.
Vibratory plates are broadly classified into two main types: air vibratory plates and solid vibratory plates. Air vibratory plates use various materials, including paper, metal, and ceramic, each possessing distinct characteristics. Paper is lightweight and easy to process, making it suitable for small speakers and microphones. Metal exhibits superior strength and durability, making it suitable for large speakers and microphones. Ceramic is lightweight with high rigidity, making it suitable for high-quality speakers and microphones.
Solid vibratory plates utilize materials such as piezoelectric ceramics, piezoelectric films, and piezoelectric elements. These materials exhibit the property of generating charges under pressure, and they are applied in devices such as piezoelectric speakers and piezoelectric microphones.
