  • Patent number: 9414154
    Abstract: A water-repellent earphone is formed of a main body and a water-repellent breathable member. The main body includes a receiving space for accommodating a speaker. The speaker partitions the receiving space to make a rear chamber. The main body includes a drainage tunnel communication with a first opening and a second opening, both of which are located on an external surface of the main body. The main body further includes a venthole communicating with the drainage tunnel and the rear chamber. The water-repellent breathable member is formed and located at the venthole. In light of the structure mentioned above, the drainage tunnel can help the earphone quickly expel the moisture to prevent the moisture from damage to the speaker and to boost the frequency response and acoustic performance within the low-frequency range.

  • Publication number: 20090136074
    Abstract: An earphone and its method of making are disclosed. The earphone comprises a first shell and a second shell joined thereto to form a housing. A sound pressure releasing path is defined in the housing. A loudspeaker is disposed in the housing. A strain relief collar is securely clasped between the first and second shells, and the strain relief collar has an inner molded body and an outer molded body. The inner molded body having a hardness, and the outer molded body has a hardness lesser than that of the inner molded body. A cord has an end connected to the loudspeaker, a portion encompassed by the strain relief collar and a portion extended out of the strain relief collar, wherein the sound pressure releasing path allows sound air waves to exit the earphone to the atmosphere when the loudspeaker imposes sound to the ear.
