Modular Acoustic Systems

A removable acoustic module comprising:

• an acoustic module housing configured to removably engage with a head-worn peripheral device such that, when engaged with the head-worn peripheral device, the removable acoustic module is arranged to provide acoustic energy proximate a user's ear;
• and,
• first circuitry arranged within the acoustic module housing, the first circuitry comprising acoustic circuitry and an acoustic transducer, the acoustic circuitry arranged to produce a first electrical signal, the first electrical signal utilized by the acoustic transducer to produce the acoustic energy proximate the user's ear,
• wherein the acoustic module housing is arranged to magnetically couple to the head-worn peripheral device such that, in a resting, coupled position, respective components of magnetic retention force are provided in at least two axial directions that are orthogonal to each other.
