ELECTRONIC DEVICE HAVING A MODE DAMPED DIAPHRAGM

摘要

The present disclosure generally provides an apparatus and method of forming an audio speaker that has an improved sound quality over conventional audio speaker designs and has a low manufacturing cost. In an effort to overcome the shortcomings of conventional sealed speaker designs that typically have diaphragms that generate undesirable levels of distortion, one or more of the embodiments of the disclosure provided herein include a speaker diaphragm that is formed from a mode damped diaphragm design. In general, a mode damped diaphragm is configured to damp the various mode shapes generated during the delivery of an acoustic output from the speaker assembly. It is believed that one or more of the embodiments of the disclosure provided herein could be used in any audio speaker application, but may provide additional advantages when used in various headphone, headset, earphone or in-ear monitor type applications.

主权项

1. An audio speaker assembly, comprising:
an enclosure comprising one or more first walls that at least partially enclose a first internal region; a sealing feature that is coupled to the enclosure, and having a sealing surface that forms an enclosed acoustic region when placed in contact with at least a portion of a user; and a speaker that is coupled to the one or more first walls, wherein the speaker comprises:
a mode damped diaphragm, wherein the mode damped diaphragm is disposed between the first internal region and the enclosed acoustic region; anda voice coil that is configured to drive the mode damped diaphragm to generate an acoustic pressure in the enclosed acoustic region and the first internal region, wherein the voice coil and mode damped diaphragm are configured to deliver an acoustic output across a first acoustic range.
