Abstract: A vibrating element includes a diaphragm and a voice coil. The diaphragm has a first surface and a second surface opposite to each other, in which the first surface includes a first conductive region and a second conductive region separated from the first conductive region. The voice coil is disposed at the first surface of the diaphragm, in which two ends of the voice coil are respectively electrically connected to the first conductive region and the second conductive region, and the two ends of the voice coil are located within a region circled by the voice coil on the first surface.

Abstract: An earphone including a housing, a speaker unit, and a gasket is provided. The speaker unit is disposed inside the housing and having a front cover. The gasket is attached between the front cover and the housing. A space inside the housing is divided into a front chamber and a rear chamber by the gasket and the speaker unit together. The front cover has a sound-output opening and a sound-leakage opening. The sound-output opening communicates the front chamber and a space inside the speaker unit. The sound-leakage opening communicates the rear chamber and a space inside the speaker unit.

Abstract: A headphone including two earphone cups, a main strap and a decorating strap is provided. Two ends of the main strap are connected to the earphone cups. Two ends of the decorating strap are detachably connected to the earphone cups or the main strap and rotatable corresponding to the earphone cups or the main strap.

Abstract: An earphone including a housing, a speaker, a tuning mechanism and an acoustic damper is provided. The housing has a sound-output opening. The speaker is disposed at the sound-output opening. The speaker and the housing together define a compartment. The speaker has an inner chamber and a through hole for communicating the inner chamber and the compartment. The tuning mechanism is movably disposed at the housing and extended into the compartment. The acoustic damper is disposed between the tuning mechanism and the speaker, and located at the through hole. The tuning mechanism is configured to move to compress or release the acoustic damper for adjusting the air permeability of the acoustic damper.

Abstract: An earphone including a housing, a speaker, a plurality of porous materials and a tuning mechanism is provided. The housing has a containing space, a sound-output opening and a plurality of tuning holes, wherein the containing space communicates with outside of the housing through the tuning holes. Areas of the tuning holes are substantially the same. The speaker is disposed at the sound-output opening and located in the containing space. The air permeability of each porous material are different, and the porous materials cover the tuning holes correspondingly. The tuning mechanism is disposed at the housing and shields at least one of the tuning holes selectively.

Abstract: An ear tip including a tube portion and an outer-umbrella portion is provided. The tube portion has a first end and a second end opposite to the first end, so that a sound output tube of an insert-type earphone may be inserted into the tube portion from the first end of the tube portion. Besides, when the ear tip is placed into an ear canal of a user, the second end of the tube portion enters the ear canal at first. The outer-umbrella portion extends from an outer surface of the tube portion and surrounds an axial direction of the tube portion. The second end of the tube portion protrudes from a top of the outer-umbrella portion.

Abstract: An ear tip including an inner-tube portion, an outer-flange portion and a bump portion is provided. The inner-tube portion is configured to be mounted to an audio output tube of an insert-type earphone. The outer-flange portion is extended from a side of the inner-tube portion, surrounds the inner-tube portion, and has a smooth outer surface. The bump portion is disposed on the smooth outer surface, so as to maintain an air-leaking channel at periphery of the bump portion when the ear tip is inserting into a canal of a user.
