An earphone comprising:
- an earphone housing having a body portion, the body portion having an acoustic output opening to output sound from a driver positioned therein into an ear of a user;
- and
- an acoustic tuning member positioned within the body portion, the acoustic tuning member having (a) an open front portion that opens toward the driver and a back portion that defines a back volume chamber for the driver and (b) an acoustic pathway acoustically coupled to an acoustic output slot formed in the acoustic tuning member.
An earphone comprising:
- an earphone housing having a body portion, the body portion forming a first chamber and a second chamber around opposing faces of a driver positioned within the body portion, and wherein the earphone housing further comprises an acoustic output opening to output sound from the first chamber into an ear of a user;
- and
- an acoustic tuning member positioned within the second chamber, the acoustic tuning member having a casing that defines a back volume chamber of the driver and an acoustic output slot formed inwardly from an edge of the casing.
An acoustic tuning member dimensioned for insertion within an earphone housing, the acoustic tuning member comprising:
