Abstract
Securing mechanisms for space access devices, such as an audio signal transmitting device, include a plurality of outwardly projecting members that are configured to transition from a relaxed state to a securing state when the space access device is inserted into an internal space or opening that has an inside diameter smaller than an outside diameter of the outwardly projecting members in the relaxed state. The outwardly projecting members securely engage a surface of the internal space and conform to the shape and size of the internal space. A sound blocking portion can be provided to substantially prevent air/sound flow past the sound blocking portion of the securing mechanism.
