You need to configure the MP3 encoder options for LAME to reduce the bitrate. Unfortunately I don't have Audacity on this machine to tell you the exact menu options, but I think it's under "Configure".

Ideally you would not only reduce the bit rate, but also enable Variable Bit Rate (VBR) encoding, assuming your target device supports it. Unfortunately I haven't found out how to do this through Audacity yet.

In Audacity 1.2.6 click on ....

Edit (menu)
Preferences
File Formats
MP3 Export Setup - Bitrate - Select a value from 16 to 320 (thousand bits per second)
OK


Audacity will remember the selected bitrate for all future mp3 exports, until you change it again.
Selecting a small value such as 32 will reduce mp3 file sizes, but will also reduce the mp3 sound quality.
