The present invention relates in general to ear muffs and in particular to an ear muff for headphones for portable radios and cassette players and the like, which may be easily removed or exchanged. The ear muff is constructed with a support cup that is covered by fabric, wool or other material which engages, and at least partially surrounds the ear of the wearer to keep it warm in cold weather. The band or strap for the headphone speaker is captured by two overlapping flaps that extend over the band or strap which are preferably locked together by mating plastic loop and hook type fasteners.
A spring biased earmuff, having a flexible and generally ring-shaped frame (2) covered on an outer side and on an inner side by a fabric material (3), the frame being flexible between an open position wherein an ear may be inserted through an elongate hole (4) from the inner side of the earmuff such that the earmuff covers the ear on the outside and on the back side, and a snap on position wherein the frame exerts a biaising force for holding the earmuff to the ear, the frame having a frame front member (5) and a frame back member (6). An earphone (L) is supported by the frame, the ear phone being covered by the fabric material on the outer side of the earmuff. The earphone is removably attached to the frame (2) in a portion thereof, from where the earphone is supported outside the auditory canal of the ear in a user position of the ear muff. The frame exerts a biaising force on the earphone, away from the ear, in the hold position of the earmuff.
A disposable device for absorbing perspiration that can be placed into the forehead area of a variety of styles and sizes of headwear. The invention consists of a flexible, liquid absorbent pad made from a material such as cloth having an absorbent nap, such as terry cloth, or absorbent paper, which may be cut by the user to fit the forehead area of the headwear. The absorbent pad may be of varying degrees of thickness. The absorbent pad is coated on one side with an adhesive, which temporarily but firmly adheres the absorbent pad to the headwear. After the absorbent pad becomes soiled, the invention can be removed from headwear by the user, disposed of, and replaced with a new absorbent pad. The non-adhesive side of the absorbent pad may be readily printable, so that advertising, slogans or other messages may be printed thereon.
A headphone assembly adapted for engaging a user's head includes an adjustable headband having first and second ends. A right ear piece is attached to a first end, and a left ear piece is attached to a second end of the headband. Each ear piece is substantially semi-circular shaped, and has a substantially inverted U-shaped shell having an inverted U-shaped inner wall. The U-shaped inner wall defines an acoustic cavity having a bottom end opening for receiving approximately the top half of the user's ear. A rear wall of the acoustic cavity has a number of holes extending therethrough behind which a speaker is mounted. An inverted U-shaped chamber is provided about the acoustic cavity and the outer perimeter of the ear piece. The right ear piece chamber will hold the electronic circuitry necessary for a cordless receiver. The left ear piece has a similar chamber which accepts a power board for holding a plurality of batteries which provides the power source for the electronic circuitry mounted in the opposite ear piece. A dome-shaped cover plate covers each of the speaker elements and the respective power board and circuit board, to create a cordless headphone wherein the user's ear is only partially enclosed by the ear piece. Foam pads mounted on the ear pieces contact the user's head to provide comfort to the user.

A dome-shaped cover plate covers each of the speaker elements and the respective power board and circuit board, with the user's ear only partially enclosed by the ear piece. Alternatively, a planar cover plate covers each of the speaker elements and the respective circuit board, and a lower ear piece is pivotally attached to the upper ear piece for movement between an open position and a closed position. The lower ear piece also includes an acoustic cavity and has an open upper end for communicating with the bottom end opening of the U-shaped inner wall.
The headband unit includes two enlarged fabric pockets disposed to overlie and cover the ears of the person wearing the unit. Each pocket is formed between two layers of fabric and contains an audio speaker support in the form of a strip of flexible plastic secured around its edges to the layer of fabric that engages the ear of the person wearing the unit, and having therein a plurality of spaced openings or slots each of which is adapted to receive and removably support an audio speaker in any of a plurality of different positions in the associated pocket so as to be registrable selectively with the ear of the person wearing the unit.
