ACOUSTIC MESH AND METHODS OF USE FOR ELECTRONIC DEVICES

摘要

An acoustically permeable material is disposed within an aperture of an electronic device to provide aesthetic appeal for the electronic device and protection for an acoustic device mounted within the electronic device. A stiffener is used in conjunction with the acoustically permeable material to improve its ability to resist permanent mechanical deformation from external forces. In some embodiments the stiffener may have multiple cavities enabling improved isolation between multiple acoustic devices within the same aperture. Other methods of employing acoustically permeable materials are disclosed that improve the aesthetic appeal, acoustic performance and/or manufacturability of the electronic device.

主权项

1. An electronic device comprising:
a housing having an outer surface opposite and adjacent to an inner surface; an aperture disposed within the housing and having an inner wall extending from the outer surface to the inner surface; an acoustic mesh having a flange portion disposed adjacent the inner surface, a vertical portion disposed within the aperture adjacent the inner wall extending from the inner surface towards the outer surface, and a horizontal portion extending across the aperture; and a stiffener having a horizontal flange disposed along the flange portion of the acoustic mesh compressing the acoustic mesh against the inner surface, and a vertical wall disposed adjacent to the vertical portion of the acoustic mesh such that the acoustic mesh is disposed between the vertical wall of the stiffener and the inner wall of the aperture.
