    Abstract: Implementations of the subject technology provide an acoustic module with fins integrated within the acoustic module to reduce acoustic noise. Airflow caused by pressure changes due to an oscillating diaphragm can be diverted by the fins within the acoustic module. The diverted airflow provide a more uniform airflow distribution within the acoustic module, which leads to a lower peak velocity and less unwanted noise. Fins may include a curved or crescent shape and may be spaced in a certain manner to divert the airflow.

    Abstract: Implementations of the subject technology provide an acoustic module with a dampening component integrated within the acoustic module to reduce deflection of a wire for a voice coil. The dampening component can take the form of an adhesive or a semisolid. During operation of the audio module, the wire vibrates and deflects in an oscillating manner. However, the dampening component can reduce the magnitude of deflection, while allowing the audio module to function in a desired manner, i.e., generate acoustical energy. By reducing the magnitude of deflection, the dampening component reduces the likelihood of mechanical fatigue of the wire, thus reducing the likelihood of damage to the wire.
