Abstract: Provided is an earphone with an open-close type enclosure in which it is possible to open or close the communicating hole of the enclosure so as to reinforce the high-pitched tones or low-pitched tones of the sound being listened to. The earphone includes a sound wave generation means 150 that generates sound waves depending on electric signals, a body 100 including an enclosure which encloses the back of the sound wave generation means, and a worn portion 200 in which a sound wave path for transmitting a sound wave to the external auditory canal is formed, and which is worn in the external auditory canal.

Abstract: An earphone has an ear cushion mounted thereon to be freely tiltable. The body includes an outer case enclosing a sound wave generating means, and a ball joint provided at an end portion of the outer case that has a sound wave path that propagates sound waves out of the body and having an opening communicating with the sound wave path. An operation holder mounted on the outer circumference of the ball joint includes a frictional ball seat whose inner surface contacts with the outer circumference of the ball joint so as to combine an internal passage communicating with the inner space of the frictional ball seat, and a periphery for the ear cushion. Thus, the earphone becomes sturdier because the body and its outer portion are not structurally weakened. Productivity improves by process simplification. The assembly of the sliding portion is done only on the outside of the body.

Abstract: An earphone minimizes the design elements for importing sound. It operates without a battery, is lightweight, harmonizes the design and ventilation of the paths for sound transmission, insulation and exhaust, and for augmenting and/or alleviating speaker vibration, and has its outer sound path and transmission path tilted. The earphone comprises a speaker, a body with a cover, a speaker sound path in the body to transmit sound toward the external auditory canal, and a worn portion including a cushion in a holder enclosing the speaker path worn in the external auditory canal. The body includes an outer sound path which imports sound. The worn portion includes a transmission path that receives the sound from the outer sound path and transmits it toward the external auditory canal. The outer sound path and transmission paths are insulated from sound from the speaker and the speaker sound path, respectively.
