Abstract
Sound-producing acoustic receivers are disclosed. The acoustic receiver includes a housing, a first diaphragm, and a motor. The housing has an internal volume separated by the first diaphragm into a first front volume and a first back volume such that the first front volume has a first sound outlet. The first diaphragm includes a first paddle movable about a first hinge. The motor is disposed in the housing and includes an armature mechanically coupled to the first paddle. The first hinge is located between opposite ends of the first paddle such that actuation of the armature pivots both ends of the first paddle about the hinge.
