Abstract:
An earphone with adjustable volume of a rear chamber between a speaker and a housing is provided, which includes a speaker unit, a housing and a movable element. The speaker is disposed within the housing, and the housing includes a chamber formed behind the speaker unit. The chamber has a volume, and the movable element is disposed on the housing and moves correspondingly with the chamber, so as to adjust the volume of the chamber. Therefore, the frequency response of the voice sent by the speaker unit is changed according to the of the volume of the chamber.
Abstract:
An earphone with adjustable volume of a front chamber between a speaker and a housing is provided, which includes a speaker unit, a housing and a movable element. The speaker unit is disposed within the housing, and the housing includes an earplug formation formed in front of the speaker unit. A chamber within the earplug formation has a volume, and the movable element is disposed on the housing and moves correspondingly with the chamber, so as to adjust the volume of the chamber. Therefore, the frequency response of the sound sent by the speaker unit varies depending upon the variation of the volume of the chamber.
Abstract:
An earphone with a sound guiding tube is provided. The sound guiding tube has an external chamber beside the ear. Compared with a conventional earphone which transmits sound directly into the ear, the earphone of the present invention has a external chamber which forms sound field outside the ear and then transmits the sound into the ear through a sound guiding tube in a particular angle. The earphone of the invention is suitable for stereo sound source or multiple-channel sound sources and will reduce damage caused by wearing the earphone for a long time.
Abstract:
An adjustable earphone with a microphone has a hook, a speaker, and a microphone, in which the hook is used for comfortably mounting the earphone on a user's ear. The speaker is mounted in a speaker chamber that connects to the hook by an outrigger wherein the speaker can be firmly fixed on the user's exterior acoustic meatus. The microphone is mounted in a microphone chamber that connects to the hook by a boom, and the microphone chamber can be fixed near the user's mouth. A speaker signal-wire used for transmitting the signal extends from the speaker chamber, passes through the hook, and then couples to the audio signal manager. A microphone signal-wire used for transmitting the signals extends from the microphone chamber, passes by the boom, and then couples to the audio signal manager.
Abstract:
An in-cord detachable ear hanger for an in-ear phone is provided. The ear hanger can protect the in-ear phone from being pulled off position from the user's ear when the user or any nearby person accidentally pulls the cable connected to the earphone set in a jerked manner. The ear hanger includes a shank body, a substantially hook-like portion, and a cable grasping means in substantially anchor-like shape. The hook-like portion is shaped in such a manner as to snugly fit to the back of a user's ear. The cable grasping means can grasp a selected portion of the cable, by which a margin length of the cable is left between the ear hanger and the speaker element inserted in the user's ear. During use of the in-ear phone, when any part of the cable other than the margin length is pulled in a jerked manner, the ear hanger would be pulled off the ear, but in most of the cases the speaker element would still stay in position in the user's ear.
