  • Patent number: 10045108
    Abstract: An earphone device is provided. The earphone device includes a pair of earphone modules. At least one of the earphone modules includes a microphone, a speaker, and a housing configured to accommodate the microphone and the speaker in an inner space thereof. The housing includes a path hole to allow the inner space to communicate outside of the housing to facilitate sound outside of the housing to enter the microphone or sound generated by the speaker to travel outside of the housing, and a partition element to partition the path hole of the housing into a first passageway and a second passageway, the first and second passageways being isolated from each other. The microphone or the speaker is housed inside the partition element. The speaker is spaced apart from the microphone at a predetermined interval and arranged to be side by side with the microphone.

  • Publication number: 20140252890
    Abstract: A vibration generation device is provided. The device includes a casing configured to have a receiving space in the casing, a coil received in a receiving space of the casing and configured to have an externally supplied current flow through the coil, a vibrator received in the receiving space of the casing, configured to comprise a magnet and a yoke surrounding the magnet, and disposed over the coil so that the vibrator is vibrated under an influence of a magnetic field through an interaction with the coil, and an elastic member received in the receiving space of the casing, disposed under the vibrator, and configured to elastically support the vibrator. There are advantages in that biased vibration can be improved because the elastic member and the yoke can be fixed at several places, a sufficient space where the elastic member can be vibrated can be secured because the elastic member is configured under the magnetic circuit.
