Mobile wireless communications device with slidable configuration providing hearing aid compatibility features and related methods

A mobile wireless communications device comprising:

• an upper housing and a lower housing being slidably connected together for sliding relative to one another between a retracted position and an extended use position, said upper and lower housings each having respective top and bottom ends, the top end of said upper housing being further separated from the bottom end of said lower housing when in the extended use position as compared to the retracted position;
• an audio output transducer carried by said upper housing and accessible to an ear of a user adjacent the top end of said upper housing;
• an audio input transducer carried by said lower housing and accessible to a mouth of the user adjacent the bottom end of said lower housing;
• and
• an antenna carried by said lower housing adjacent the bottom end thereof so that the ear of the user is further separated from said antenna when said upper and lower housings are in the extended use position.

A method for making a mobile wireless communications device for a user wearing an electronic hearing aid adjacent an ear of the user, the method comprising:

• slidably connecting an upper housing and a lower housing together for sliding relative to one another between a retracted position and an extended use position, the upper and lower housings each having respective top and bottom ends, the top end of the upper housing being further separated from the bottom end of the lower housing when in the extended use position as compared to the retracted position;
• positioning an audio output transducer adjacent the top end of the upper housing to be accessible to the electronic hearing aid of the user;
• positioning an audio input transducer adjacent the bottom end of the lower housing to be accessible to a mouth of the user;
• and
• positioning an antenna adjacent the bottom end of the lower housing so that the electronic hearing aid of the user is further separated from the antenna when the upper and lower housings are in the extended use position to thereby reduce undesired coupling from the antenna to the electronic hearing aid.
