The invention relates to an ear plug to be inserted into the auditory meatus of an ear, having an exterior member of a soft flexible material and an interior tubular member which extends through the exterior member from one end thereof, and having manually operable means, operatively connected with the exterior as well as the interior member, operable to cause an expansion of the exterior member and thereby engage the exterior member firmly against the wall of the auditory canal.
An ear plug to be inserted into the external auditory canal, having a compressible sleeve member and a core member attached therein, the improvement in which plural projections or a single projection are formed intermittently or continuously on an exterior of the core member, and vent is formed through or along the projection to make the external auditory canal communicate with the external atmosphere when inserted into the external auditory canal. A communicating passage or vent to an effective degree for remarkably decreasing the pressure difference between the inside of the external auditory canal and the external atmosphere as well as preventing leakage of sound causing so-called howling.
An ear clean button for cleaning and absorbing the wax and the moisture in a person's ear including a narrow insertion portion for inserting into the person's ear and an enlarged portion to limit the insertion of the insertion portion into the person's ear. An opening extends centrally through the button, and a wax collector is disposed within the opening adjacent to an end surface of the insertion portion for collecting the removed wax. The wax collector includes a hollow cone, a mouth of the cone being disposed at the end surface of the insertion portion with peripheral side walls of the mouth engaging the side walls of the opening, where the closed end of the cone is disposed within the opening. A handle-like introducer is provided for supporting the button, where an end portion of the introducer is removably inserted into the opening of the button from the end surface of the enlarged portion of the button. The end portion of the introducer is provided with an end opening therethrough to receive the cone therein. The introducer has a reduced portion so that the end portion of the introducer can be bent. Preferably, the button is fabricated from a sponge material, and the introducer is fabricated from a plastic material.
A hollow earpiece has a bulbous section for insertion into the ear canal and a flange section joined to the bulbous section by a neck with an opening in the tip of the bulbous section to allow water from the ear canal to enter into the bulbous section and an elongated hollow tube coupled to the earpiece at the earpiece neck with one open end of the tube located within the bulbous section and the other open end adaptable for applying a suction to remove water from the user's ear.
An earpiece which takes the form of a pouch made of a plastics foil which surrounds a less pliant plastics tube in an airtight manner and is filled with a sluggishly moving jelly-like paste. A not readily movable compression ring provided with a funnel shaped portion which is clear of the tube ensures that the pouch is filled in such a way that during use the pouch perfectly engages with the inner wall of the auditory canal.
A hearing protector has a body made of a suitable material and matching the shape of the auricle or ear shell and/or the auditory canal of the user. The body is provided with a canal which, in the condition wherein the body is placed within an ear of the wearer, provides communication between the auditory canal and a free space of the body. The body includes a second canal which, like the first canal, extends between the auditory-canal end and the free-space end of the body. An adjustable damping member is provided in or on the first canal for damping sound to suit the wearer's comfort in conditions in which the device is used.
