A headphone supported at the ear position for reproducing sound comprises (a) an oscillating member for sound reproduction, (b) a frame to support the oscillating member, (c) at least one opening constituting a path from the space, defined by the inside of the oscillating member, an ear pad and the ear to the free space on the outside of the oscillating member, and (d) an acoustic resistance member disposed in the opening.
A speaker system which has a speaker unit with a diaphragm and an acoustic path provided on the front side of the diaphragm so as to guide sound waves emitted from the diaphragm. The acoustic path is defined by a sound absorbing member. The space in the acoustic path and the sound absorbing member is separated by a partition member which is disposed in such a manner that at least a portion of the sound absorbing member is exposed to the space in the acoustic path, except that the portion of the sound absorbing member just adjacent the diaphragm is not exposed to the acoustic path. This arrangement eliminates peaks and troughs of resonance determined by the length of the acoustic path, so that flat sound pressure frequency characteristics can be obtained over a wide range up to high-pitch tone region.
In one embodiment, a cushioned extension for a telephone earpiece has bodies connectable to the male threads on a standard telephone handpiece. In a second embodiment the cushioned extension partially surrounds the handle portion of the handpiece and is anchored thereto by plates overlying the inner portion of the handpiece handle. A cushioned extension for the earpiece of a telephone handset has upper portions which extend outward from the earpiece and which terminate outwardly in a radially extending flap arcuate rim. A cushion having two similar arcuate parts is connected to the outward extension of the body and to the rim in each embodiment. A first part of the cushion overlies the rim for contacting the head of a user in an area surrounding an upper part of the pinna of an ear. The inner cushion part fits within the body extension for resting softly against an earlobe of the user without pressing the earlobe against the user's skull. The cushions are attached to the rim and to the body by micro hook and loop-type fasteners connected to the inner cushion and to the inner surface of the body extension and to the rim and flap of a covering of the outer cushion.
A cushion for application to a telephone handset. The cushion is made from a low density, high resiliency flexible foam to make the telephone's receiver or transmitter more comfortable when pressed against the ear or mouth of the user. The cushion has a main body which defines a funnel shaped channel for guiding sound between the handset and the user. A diaphragm with sound ports completely cover the channel to dampen the sounds passing between the handset and the user. The cushion is shaped to match the receiver or transmitter of the telephone handset and can include a groove to allow the cushion to hang from a wall mounted base and tabs to conduct electricity from recharging pins to rechargeable batteries in the handset. A variety of coverings can be placed over the cushion for aesthetic or functional purposes.
