Ultrasonic sound speaker cones made of paper
Paper is a cost-effective and generally available material. Paper cones were used in the majority of earlier speakers. Paper is a thin, lightweight substance that can follow the motions created by the coil. Paper is a low-cost material, especially for large speaker cones. Paper, on the other hand, absorbs moisture, which increases its mass while changing its damping properties. Paper cones are also prone to tearing when stressed. They are readily punctured.
Paper cones are essentially a mixture of many materials, particularly a combination of wood, wool, and felt. The paper compositions are also blended with a variety of chemicals to make them more robust and suitable for the production of speaker cones. As a result, depending on the manufacturer’s design, paper cones can be formed of various combinations.
During the production process, paper speaker cones are either pressed or unpressed. Non-pressed cones have a wider surface area, which allows them to push more air and produce louder sounds. Non-pressed paper cones are also more sensitive, which means they use less energy. Chemical treatment, on the other hand, makes non-pressed paper firmer. Pressed paper cones, on the other hand, have a lower surface area but are said to have fewer quality problems than non-pressed paper cones.
