米島フエルト産業 List of Products and Services

Our company's vibration membranes are developed in collaboration with various film manufacturers, allowing us to propose composite materials tailored to specific development purposes. For high-output overseas smartphone and tablet speaker vibration membranes, we can offer materials with higher heat resistance, and for improving sound pressure in the low-frequency range, we can suggest softer materials. This time, we would like to introduce a case where we addressed a request from an acoustic manufacturer. 【Challenge】 The acoustic manufacturer requested a film that could attenuate vibrations for both high and low sounds. 【Proposal】 Since different films are required for high and low frequencies, we proposed a combination of two types of films. 【Result】 We were able to produce the desired sound for both high and low frequencies, achieving a high attenuation effect that greatly pleased the acoustic manufacturer. *For more details, please download the PDF or contact us.
