  • Patent number: 9193581
    Abstract: An MEMS microphone package structure includes a substrate, a carrier and an acoustic transducer. The carrier covers the substrate from above and connects to the substrate. The carrier has an n-shaped cross section and includes a flat plate portion, a sidewall connected to the flat plate portion, and two oblique blocks protruded from the inner surface of the sidewall. The oblique blocks each have an inclined surface for connecting the flat plate portion and the bottom surface of the sidewall. The acoustic transducer is posited on the bottom surface of the flat plate portion and electrically connected to the substrate through a plurality of electrical conduction paths passing through the inclined surfaces. The electrical conduction paths are conducive to simplification of wirings of the substrate and the thinning of the substrate. Therefore, simplify the manufacturing process to reduce the manufacturing time and cost.

  • Publication number: 20150304751
    Abstract: A chip-stacked microphone includes a cover, an acoustic wave transducer module, an application-specific integrated circuit chip (ASIC) and a substrate arranged in proper order from top to bottom. The cover is connected to the substrate and covered over the acoustic wave transducer module, providing a sound hole. The application-specific integrated circuit chip (ASIC) is electrically connected to the substrate. The acoustic wave transducer module is electrically connected to the application-specific integrated circuit chip (ASIC) using a 3D packaging technology, allowing an acoustic wave to pass therebetween. Thus, the invention greatly reduces the area for footprint and fully utilizes the space between the cover and the two modules for back chamber to maintain the overall performance of the microphone.

  • Patent number: 9162869
    Abstract: A MEMS microphone package structure having a non-planar substrate includes the non-planar substrate, a cover plate, and a sound wave transducer. The non-planar substrate has a carrying bottom portion and a sidewall. The carrying bottom portion has a sound hole. The cover plate covers the non-planar substrate from above and connects to the sidewall. Both the cover plate and the sidewall have a metal layer for shielding the microphone from electromagnetic interference. The sound wave transducer is located corresponding to the sound hole. Hence, the sidewall reinforces the non-planar substrate, such that the carrying bottom portion is thinned without weakening the non-planar substrate, so as to increase the capacity of a back chamber of the microphone without changing the appearance and dimensions of the package structure.

  • Patent number: 9036838
    Abstract: A dual-diaphragm acoustic transducer includes a substrate defining an opening, an inner diaphragm and an outer diaphragm concentrically mounted at one same side of the substrate corresponding to the opening of the substrate, and a plurality of elastic supporting members connected between the outer perimeter of the inner diaphragm and the inner perimeter of the outer diaphragm. Thus, when a sound wave enters the opening of the substrate, the sound wave pressure forces the outer diaphragm to displace and to carry the inner diaphragm to move, and the inner diaphragm itself will also be forced by the sound wave pressure to have a larger displacement than the outer diaphragm, enhancing the sensitivity. Further, using the inner and outer diaphragms to respond to different sound wave pressures can enhance the sound wave pressure sensing range.

  • Publication number: 20150109889
    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.
