ELECTRO-ACOUSTIC DRIVER

A bobbin for an electro-acoustic driver includes an outer surface, a substantially planar surface at an end of the bobbin, and a bobbin axis that is substantially coaxial with a housing axis. The bobbin is disposable inside a housing and configured to move along the bobbin axis. The substantially pl...

Beschreibung
Zusammenfassung:	A bobbin for an electro-acoustic driver includes an outer surface, a substantially planar surface at an end of the bobbin, and a bobbin axis that is substantially coaxial with a housing axis. The bobbin is disposable inside a housing and configured to move along the bobbin axis. The substantially planar surface at the end of the bobbin is securable to an acoustic diaphragm. The bobbin includes one or more of (a) legs extending from the outer surface to the substantially planar surface, (b) a wall which extends about substantially all of a perimeter of the planar surface, and (c) a plurality of through holes in the substantially planar surface.
