Composite Speaker Unit

Strongness and Stiffness

The basalt fiber provides high tensile strength and rigidity to enhance the durability of the speaker cone.
This means that it is more robust and durable than paper or PP cone.
Vibration Resistance

The basalt fiber has excellent vibration resistance, allowing cleaner and more accurate sound reproduction.
Paper cones have low vibration resistance, and PP cones are intermediate.
Heat resistance

Thermoplastic composite materials have high thermal resistance, so their performance is maintained even in high-temperature environments.
Paper cones are weak in heat, and PP cones have lower thermal resistance than thermoplastic composite materials.
Humidity and corrosion resistance

The basalt fiber is resistant to humidity and corrosion, so the performance of the speaker cone is maintained even in humid environments.
Paper cones are weak in humidity, and PP cones perform better in these environments.
Lightness

The thermoplastic basalt composite material provides light weight while maintaining strength.
This increases the efficiency of the speaker.
Environmentally Friendly

Basalt is a natural resource, and its use is less harmful to the environment On the other hand, PP is a synthetic resin, which may have a greater environmental impact.
