    Abstract: An acoustic transducer includes a base plate, a vibrating membrane and a back plate. The vibrating membrane covers an opening of the base plate and has a plurality of conjoint vibratile portions and a plurality of elastic structures. The elastic structures are concentrically arranged along peripheries of the vibratile portions. The acoustic transducer further has a connecting portion extending from the back plate to a boundary between each two of the adjacent vibratile portions so as to allow the vibratile portions to generate vibration independently. The elastic structures include a first elastic structure and a second elastic structures arranged alongside of the boundary, and a third elastic structure arranged along an outer periphery of the vibrating membrane. The vibratile portions are geometrically different from each other and different in rigidity, and the vibratile portions can vibrate independently to respond to various sound pressure levels.

  • Publication number: 20170257708
    Abstract: An acoustic transducer includes a base plate, a vibrating membrane and a back plate. The vibrating membrane covers an opening of the base plate and has a plurality of conjoint vibratile portions. The acoustic transducer further has a connecting portion that is connected to a boundary between each two of the adjacent vibratile portions so as to allow the vibratile portions to generate vibration independently. The vibratile portions are geometrically different. Thereby, the vibratile portions can vibrate independently. This allows a designer to easily enhance the dynamic range of the acoustic transducer by geometrically modifying the vibrating membrane without increasing the total area of the vibrating membrane while maintaining a certain good degree of sensitivity and signal-to-noise ratio.
