发明名称 WAX RESISTANT EARPIECE TIP
摘要 A wax-resistant earpiece tip has one or more sound openings and a torturous path to inhibit wax from reaching a receiver mountable therein. The tip may further include a folded acoustical horn. A chamber may be formed in the tip to collect debris. The tip may include a stop bar to prevent the tip from collapsing against a receiver sound port.
