Abstract:
Implementations of the subject technology provide vented audio transducers such as vented speakers. A speaker assembly may define a first volume under a dome of the speaker and a second volume under a surround of the speaker. The first volume and the second volume may be separated by a speaker structure such as a voice coil. By venting the first volume to the second volume, the disclosed vented speakers can provide a flatter response at high frequencies and lower distortion relative to conventional speakers, by equalizing the pressure under the diaphragm during operation.
