Abstract
An electro-acoustic communications unit (20) may include an acoustic driver (22) which, when operated, emits acoustic waves in two directions. A hermetically sealed container (24) attached to the acoustic driver may include a gas other than air. The gas may transport acoustic waves generated by the acoustic driver.

An electro-acoustic communications unit, for mounting in a cellular phone, comprising:
- an acoustic driver which, when operated, emits acoustic waves in two directions;
- and
- a hermetically sealed, flexible container directly attached to the acoustic driver and comprising a gas other than air, which gas transports acoustic waves generated by the acoustic driver, wherein a portion of the hermetically sealed container forms a membrane of an acoustic signal generating element of the acoustic driver.
An electro-acoustic communications unit for mounting in a cellular phone, comprising:
- an acoustic driver which, when operated, emits acoustic waves in two directions;
- and
- a hermetically sealed, flexible container directly attached to the acoustic driver and comprising a gas other than air, which gas transports acoustic waves generated by the acoustic driver, wherein the acoustic driver comprises an acoustic signal generating element that includes a first side of a membrane and a second side of a membrane, where the second side of the membrane is directly attached to the hermetically sealed container.
A portable electronic device comprising an electro-acoustic communications unit comprising:
- an acoustic driver which, when operated, emits acoustic waves in two directions;
