Publication number: 20240064479Abstract: A balanced armature receiver can include a motor disposed in a case. The motor can include an armature having a first portion fixed to and extending from a yoke and a second portion extending through a coil tunnel. The second portion can have a free end-portion movably disposed in a magnet gap. The balanced armature receiver can include a damping compound-locating structure disposed on one or both of the armature and another portion of the receiver proximate the armature. The balanced armature receiver can include damping compound contacting the damping compound-locating structure and located between the armature and another portion of the receiver.Type: ApplicationFiled: August 16, 2022Publication date: February 22, 2024Inventors: Christopher L. Monti, Thomas E. Miller, Charles B. King, Kalyan Nadella, Mohammad Mohammadi

Patent number: 11438702Abstract: 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.Type: GrantFiled: December 26, 2020Date of Patent: September 6, 2022Assignee: Knowles Electronics, LLCInventors: Kalyan Nadella, Thomas Miller, Shehab Albahri, Yahui Zhang
