Description

Stereo earphone device, earphone and earphone insertion method {A STEREOPHONIC EARPHONE APPARATUS}

The present invention relates generally to the field of stereophonic earphone apparatus. In particular, a preferred embodiment of the present invention relates to a stereo earphone device for insertion into an ear canal of a user.

As is known to those skilled in the art, various earphone devices have been proposed for positioning in the vicinity of the user's ear canal openings. Thus, a recognized problem of the prior art is that such earphones are not comfortable. Needless to say, there is a need for earphones that can be worn for a long time without the wearer feeling uncomfortable.

Various means have been proposed for supporting the earphones so that the earphones fit comfortably in the user's ears. However, these prior art devices have not been successful in achieving this goal.

In addition, in the earphone device of the prior art, noise from the outside leaks through the earphone into the ear hole of the user, and thus tends to reduce the quality of the reproduced sound waves.

In summary, the present invention relates to a stereo earphone device for insertion into a user's ear hole. The apparatus includes a housing having a first end and a second end. The housing defines an enclosure for receiving an electroacoustic transducer therein. A diaphragm is disposed in a seal adjacent to the transducer, which defines a flange of the outer circumferential surface that is connected to the housing to allow the diaphragm to operatively cooperate with the transducer for generating sound waves. The cover is secured to the second end of the housing such that the diaphragm is disposed between the cover and the transducer.

The elastic anchor has a first extreme end and a second extreme end, the first extreme end being removably fixed to the lid and extending from the lid. The anchor is made of hydrophilic urethane foam with a leather covered outer surface to allow insertion of the anchor into the ear canal when the anchor is compressed. After the anchor is inserted into the ear hole, the foam gradually expands so that the foam-covered surface is in close contact with the ear hole. In this way, the device is firmly supported in the ear canal.

The anchor is generally conical in shape and tapers inwardly from the first extreme to the second extreme. The anchor also defines a longitudinal passage having a first termination and a second distal end, the first distal end being disposed adjacent the cover and the first extreme end of the anchor. The tube extends from the cover and is disposed in the passageway. The tube has an inner side and an outer side, and this arrangement allows the outer side of the tube to extend closely along the passageway, thereby preventing the closure of the passageway while allowing the transfer of sound waves from the diaphragm to the ear canal.

The present invention includes a method for inserting an earphone into an ear hole of a user, the method comprising: compressing an elastic foam anchor between a user's fingers; Successively inserting the anchor into the ear canal; Finally, the foam anchor gradually expands such that the outer surface covered with the leather of the foam becomes a shape close to the shape of the ear canal, such that the anchor and its attached housing are comfortably secured to the user's ear.

The effect of the present invention is to improve the transmission of sound waves from the transducer to the ear canal of the user. It is a first object of the present invention to provide a device that is comfortable to wear. It is a further object of the present invention to provide a unique device that allows for comfortable accommodation of an elastic anchor in the user's ear hole in order to provide a high fidelity sonic connection between the device and the user's ear hole.

Another object of the present invention is to provide an earphone device which optimizes the natural acoustic response of the device and provides its precise frequency response.

These and other aspects and objects of the present invention will be better understood and understood when referring to the following description and the accompanying drawings. However, it will be understood that the following description represents preferred embodiments of the present invention but is for purposes of illustration and not limitation.

Dotted line 68 shows a comparison graph of a typical commercial foam earplug listening protector. Also, a reference diagram of the noise is shown.

In the operation of the device according to the invention, the user compresses the elastic anchor 30 between the fingers of the user and then slowly inserts the anchor into the ear hole 12 as best shown in FIG. 2. Subsequently, the foam 36 gradually expands so that the outer surface 38 covered with the leather of the foam is shaped to approximate the shape of the ear hole 12, so that the anchor and the housing 14 attached thereto are most likely to have the shape shown in FIG. As shown well, it is comfortably supported on the user's ear.

In addition, heat from the user's ears is passed through the leather-covered surface 38 to the foam 36, thereby softening the foam near the inner surface of the ear canal. Thus, the anchor 30 is supported much more comfortably in the ear canal. Furthermore, noise from outside the outer surface is sealed from the ear canal by close matching of the ear hole 12 and the leather-covered surface 38.

The present invention provides a unique stereo earphone device that fits comfortably in a user's ear hole and provides improved frequency response and improved low range frequency performance.

Moreover, the individual components of the device need not be formed or assembled in the shape shown, the device being provided in substantially any shape and substantially any shape so that it can be combined with other devices and integrated with the device. The furnace can also be assembled.

The appended claims are intended to cover all such additions, changes, and rearrangements. Exemplary embodiments of the invention are differentiated by the appended dependent claims.

The foam expands gradually after the anchor is inserted into the ear hole, so that the leather-covered surface comes in close contact with the ear hole, allowing the earpiece to comfortably fit in the ear and providing a seal that blocks noise from the outside into the ear hole. It can optimize response, provide precise frequency response, and especially excellent extreme low range frequency performance.
