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.
