发明名称 AIR CONDUCTION HEARING DEVICE
摘要 A two-piece hearing aid with a soft flexible snap-on covering (10) with a plurality of folding sections which contribute to the proper fit, comfort, ease of maintenance and prevention of earwax build-up interference. The end of the snap-on insert has a thin sound permeable membrane (16) which does not allow earwax into the hearing aid. In addition a directional winddramp (5) redirects wind away from the microphone opening (6) to greatly reduce ambient wind noise.
