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.

Abstract: Aspects of the subject technology relate to stiffness reduction for audio transducers, such as speakers. Stiffness reduction can be provided using one or more magnetic structures configured to move with a voice coil and/or a diaphragm of the speaker, and assist in the motion of the voice coil and/or diaphragm via magnetic interaction with one or more magnets of the speaker. In one or more implementations, the one or more magnetic structures may form a tri-stable system with the one or more magnets.

Abstract: Aspects of the subject technology relate to a device comprising a moving-coil speaker including a diaphragm to play low-frequency signals from an audio-signal source, and a piezoelectric transducer coupled to the diaphragm to play high-frequency signals from the audio-signal source. A coupler couples the diaphragm to a housing of the device.

Abstract: Aspects of the subject technology relate to electronic devices having speakers. An electronic device may operate a pair of speakers to in a way that mitigates electromagnetic interference with a display of the electronic device. For example, the speakers may be operated acoustically and mechanically in phase, and electrically out of phase, to mitigates interference with a display of the electronic device.
