Abstract
An electronic device having several speaker modules that are acoustically in-phase and mechanically out-of-phase is disclosed. Embodiments include a pair of speaker modules mounted at respective ends of a lateral link, and the lateral link may be supported relative to a housing of the electronic device. The speaker modules may receive a same audio signal, and the audio signal may drive a first voicecoil in a first direction and a second voicecoil in a second direction. Accordingly, the speaker modules may be driven in mechanically different directions by the same audio signal, such that reactive forces cancel and/or mechanical energy is dissipate in the lateral link between the speaker modules. Other embodiments are also described and claimed.
