Abstract
Aspects of the subject technology relate to electronic devices having speakers with resonators, such as Helmholtz resonators, acoustically coupled to the front volume of the speaker. A speaker module for an electronic device may include multiple resonators, including a first resonator that is acoustically separate from, and at least partially disposed within a second resonator. An acoustic barrier between the first resonator and the second resonator may have a liquid resistance that is different from a liquid resistance that is provided between the first resonator and a back volume of the speaker module and/or between an external environment of the speaker. In one or more implementations, a third resonator may be provided, that is spatially separated from first and second nested and/or adjacent resonators.
