More Information
Summary:An earphone with a drainage tunnel includes a body and a waterproof ventilation part. An accommodation space is established inside the body for accommodating a speaker, and a back cavity is defined in the accommodation space. In addition, the body also includes a drainage tunnel connected to a first opening and a second opening on an outer surface of the body. A ventilation hole that connects to the drainage tunnel and the back cavity is set inside the body. The waterproof ventilation part is formed on the ventilation hole. As a result, the drainage tunnel is able to drain the water out of the earphone rapidly to prevent damaging the speaker, and also enhance the frequency response and the sound output performance at low frequencies of the earphone.
