Abstract: A transducer assembly comprising: an air motion transformer having a magnet assembly operable to provide a magnetic field and a folded diaphragm having conductive traces and operable to expand or contract in a first direction and emit a sound in a second direction perpendicular to the first direction; and a ferromagnetic assembly comprising a number of fixed members arranged within folds of the folded diaphragm to provide a closed loop magnetic circuit that drives the expansion or contraction of the folded diaphragm.

Abstract: Systems of the present disclosure include an electronic device with a chassis and a speaker assembly. The speaker assembly can include a speaker support surrounding a speaker and coupled to the chassis via a spring element. The spring element can be monolithically formed with a main body of the speaker support and be configured to reduce transmission of vibrations from the speaker to the chassis. For example, the spring element can include an arm that extends within an opening of the main body to connect the main body to a fastener secured to the chassis. The spring element can be provided with features that facilitate wide distribution of loads and relative movement between the speaker assembly and the chassis.
