Abstract:
Disclosed is a noise cancelling earset having an acoustic filter. The earset includes a dynamic driver unit configured to generate a sound, and an acoustic filter configured to cover a back hole formed in a back of the dynamic driver unit, so that the acoustic filter allows air to pass, but does not allow extraneous noise to pass. The acoustic filter includes filter layers selectively formed with a through-hole and a sound passage, and plates with a through-hole selectively communicating with the through-hole and the sound passage. The filter layers and the plates are alternatively disposed on each other, and the through-holes of the plates communicate with the through-holes or the sound passages of the filter layers.

Claim (Index 9):
The noise cancelling earset according to  claim 8 , wherein the dynamic driver unit includes\n a conical hollow frame, a conical hollow vibrating diaphragm vibrating in the frame, an edge surround elastically supporting a front end of the vibrating diaphragm at a front end of the frame, a bobbin with a front end adhered to a center portion of the vibrating diaphragm from a rear side of the vibrating diaphragm, a damper with an outer peripheral portion fixed to the frame and an inner peripheral portion adhered to the bobbin, a voice coil wound around the bobbin, a spider supporting the voice coil, a ring-shaped permanent magnet disposed around the voice coil, a ring-shaped front plate firmly disposed between the frame and the permanent magnet, a ring-shaped rear plate covering a lower portion of the permanent magnet, a ring-shaped pole piece protruding in the bobbin from the rear plate, with a vibration space where the bobbin vibrates up and down being provided between the permanent magnet and the front plate, and a dust cap disposed at a center of the vibrating diaphragm.
