Mylar diaphragm and plastic frame, plus a strong Neodymium magnet, for high output from an incredibly tiny driver.

The Commercial Engineering (CE) series of speaker drivers from Dayton Audio provides engineers, designers, and integrators with a line of economical small drivers that fit the diverse range of applications found in consumer electronics and audio-enabled electronic projects.


It’s so tiny! The CE20-14M-8 micro speaker is the smallest driver in Dayton Audio’s CE Series. Featuring a racetrack-shaped, lightweight Mylar diaphragm and neodymium magnet, the CE20-14M achieves useful levels of audio output from a speaker that’s only ½” wide and ¾” long, for the very smallest audio applications. Its uses include telephone handsets, tablet PCs, and even miniature on-ear headphones.
