When the earphone microphone is inserted in the external acoustic meatus, the first opening is communicated with the external acoustic meatus while the second opening is communicated with outside of the main body case other than the external acoustic meatus.

Provided is a sound processing system and a sound processing device, which are capable of detecting attachment/detachment of an earphone microphone without adding a signal wire for detection. The sound processing system includes an earphone microphone and a sound processing device. The earphone microphone includes a speaker and a microphone. The speaker outputs an output sound. The microphone outputs a collected sound signal corresponding to collected sounds, and collects echo sound of the output sound echoed in an external acoustic meatus in a state where the earphone microphone is placed in the external acoustic meatus. The sound processing device includes an attachment determinator, which determines whether or not the earphone microphone is placed in the external acoustic meatus based on a variation of the collected sound signal.

A two-way communication earpiece, which is a small and comfortable. The ear-piece is comprised of a main body, a sound delivery probe, and a micro probe for sound pick up. The sound delivery probe, which is extended from main body, is configured to be inside of the external acoustic meatus of a user. The main body is attached to lobule of ear of the user like an ear ring. The sound delivery probe is coated with silicon for hygiene of the external acoustic meatus of the user. The micro probe for sound pick up is attached to a junction point of user's skin that locates behind the ear of the user, where rear surface of the antihelix, rear surface of the lobule, and neck skin of the user meets. At that point the microprobe picks up the voice of the user from the vibration of the skin.

A headphone device includes: a driver unit held in the vicinity of the external acoustic meatus of an ear; and an arm in a predetermined shape formed integrally with the driver unit and extending from the driver unit, wherein an end of the arm is kept abutting on a part of the auricle near the base the auricle on a back side thereof to support the device at two support points provided by the driver unit and the end of the arm.

Briefly, in accordance with one or more embodiments, a headphone device, comprises at least one ear muff comprising a structure to hold the at least one ear muff against an ear of a user, and at least one driver disposed in the at least one ear muff An earbud comprises an earbud housing having a protrusion to fit into an external acoustic meatus or ear canal of a user, and a driver disposed in the earbud housing. The driver comprises an electrostatic acoustic transducer comprising a substrate comprising a first material to function as a first electrode, a dielectric layer coupled with the first material, wherein the dielectric layer has one or more cavities formed therein, and a membrane coupled with the dielectric layer to cover the one or more cavities and to function as a second electrode.

The invention discloses traditional Chinese medicine powder for treating otitis media. The otitis media can be caused by a plurality of diseases or trauma, and is diversified in pathogenesis, for example, certain boundedness existing in treatment by simply using antibiotics or steroid, and risks of resistance to drugs and side effects existing in use of the antibiotics.
